KANYIKA NIOBIUM PROJECT
PROJECT FEASIBILITY AND ECONOMICS
Globe Metals & Mining Limited (ASX: GBE , Globe or the Company ) is extremely pleased to provide an overview of the Kanyika Niobium Project Feasibility and Economics following the grant of a Large-Scale Mining Licence for the Kanyika Niobium Project in Malawi to Globe’s wholly owned Malawian subsidiary Globe Metals & Mining (Africa) Limited.
The results of the Feasibility Study highlight a robust project with strong financial returns.
STUDY HIGHLIGHTS:
-
Kanyika Niobium Project is positioned to be the first niobium mine in Africa and the first new producer in 50 years.
-
Over 90% of niobium is used in the manufacture of High Strength Alloy Steels. Steel production is growing year on year. Intensity of usage in steel is rising rapidly as markets, and in particular China, moves towards the manufacture of higher quality steels.
-
Niobium’s unique characteristics make it central to many of the world’s past, present and future technologies with scientists and manufacturers only now beginning to imagine the range of technological applications for niobium.
-
Niobium is critical to military, aerospace, space and medical industries and becoming increasingly important in quantum electronics, in the manufacture of semiconductors and in the electrical vehicle industry.
-
Globe will target high-end, high-value applications for niobium.
-
A mine life of ~ 23 years with capability to extend mine life to 38 years subject to the conversion of inferred resources through further drilling.
-
The Feasibility Study is based on material assumptions outlined in this announcement. Globe considers the material assumptions to be based on reasonable grounds, there is no certainty that they will prove correct or that the range of outcomes indicated will be achieved.
-
Average annual production of 3,250 tonnes of niobium and 140 tonnes of tantalum.
-
High metal recoveries of ~75% for niobium and ~73% for tantalum
-
Patented metallurgical advancements ( commercial in confidence ) provide competitive advantage allowing substantially simpler beneficiation with greater recovery and lower process OPEX.
-
Pre-production capital costs of ~USD250m.
-
KNP will generate revenues of USD5.6B over its 23-year mine life, valued at a base price of US$55/kg for Nb2O5 and US$410/kg for Ta2O5 mostly as Tantalum K-Salts.
-
Net Present Value of US$1B (pre-tax) at a discount rate of 8% per annum.
-
Internal Rate of Return of ~50% (pre-tax).
-
Payback period of ~ 1.5 years (from first production).
-
All approvals in place to immediately commence construction upon funding and relocation of affected persons.
The Kanyika Niobium Project promises to be a world-leading project, utilising state-of-the-art technology for a state-of-the-art metal. It is projected to employ and train thousands of local staff over its life, and through the many community programs envisaged, it can be expected to improve the lives of the Kanyika community and make for a better Malawi.

EXTRACT OF FEASIBILITY STUDY
OVERVIEW
This feasibility study was undertaken to establish the most appropriate configuration for the Kanyika Niobium Project ( KNP or Project ) and to determine its economic feasibility.
The KNP is geographically located in central Malawi, approximately 250 km north of the capital Lilongwe. The mine will produce about 260,000 tonnes of niobium and tantalum concentrate over the 23-year life of operations and on average about 11,300 tonne per annum. Concentrate will be transported to a refinery for processing into a marketable product. The refinery will produce high-purity and high-quality niobium and tantalum products to customer specification.
Key Aspects:
-
The 2018 Mineral Resource estimate (MRE), that is consistent with the JORC Code guidelines (2012), consists of 68.3 million tonnes of mineralisation with a grade of 2,830 ppm Nb2O5 and 135 ppm Ta2O5.
-
The feasibility study has resulted in a mineral mining inventory (Ore Reserve) of 33.8 Mt at a grade of 3,038 ppm Nb2O5 and 141 ppm Ta2O5 and supports a mine life of 23 years.
-
Mining will involve conventional open pit mining, consisting of drill-and-blast followed by load-haul using 70 tonne shovels and 40 tonne off-road articulated haul trucks. The life of mine average strip ratio is 1.54 waste to 1 ore (SR W:O 1.54:1).
-
Mineral processing of ore will involve comminution at a rate of 1.5 million tonne per annum;
-
Comminution involves crushing, followed by Semi-Autogenous Grinding (SAG) and ball milling in a closed circuit with Derrick screen classifiers.
-
Concentration involves magnetic separation, flotation beneficiation and gravity separation to produce a (niobium/tantalum) pyrochlore mineral concentrate.
-
Mineral concentrate from the mine is transported by road, rail, and ship to the refinery.
-
Construction of supporting infrastructure at the mine site is needed to allow a continuous highavailability operation, including a river diversion, roads, a tailings storage facility, camp and general buildings, water supply, and grid power connection.
-
The initial capital investment for the Kanyika mine site is forecast at US$200M expended over a 24-month development period. Refinery capital investment is estimated at US$50M. Mine site sustaining and deferred capital of US$80M will be deployed over the life of operations funded from cash flow and US$20M for the refinery over the life mine.
-
Revenue from refinery sales is valued at a base price of US$55/kg for Nb2O5 and US$410/kg for Ta2O5 generating revenue, with by-products, of US$5.6B.
-
Total operating costs average US$70 million per annum with logistics, sales, and marketing costs to average US$13M per annum.
-
Total environmental management costs during operations and for post operations rehabilitation total US$48m.
-
Marketing studies evaluating the sale of niobium and tantalum products remain works-in-progress at the time of this study with pricing sourced from research reports and communication with marketing specialist groups. The current business case for Kanyika mine involves the sale and export of all mineral concentrate.

PROJECT DETAILS
CAPITAL INVESTMENT
The projected capital investment requirement of US$250 million[1] comprises the major components detailed below:
-
US$200M for Plant Property and Equipment “PPE” and community relocation,
-
US$50M for refinery property, plant and equipment,
-
10% each for both EPCM and contingency;
-
and US$10M of owner development team management costs.
Additional costs are associated with:
-
US$15M for head office and administrative management over three years of development,
-
US$20M for working capital on commencement of production.
The quality of the engineering studies for a large proportion of the plant design qualifies the project as a Class 3, FEL3 standard under AACE[2] practices with components at Class 4, FEL2. Since the study has been completed a significant time has passed related to the negotiations on the Development Agreement with the Government, resulting in the associated quotations and related cost estimates being outdated. Parts of the plant where intellectual property has enhanced project metrics are at prefeasibility status where a capital estimate has been allocated but the quantum is not significant to total capital costs but is material to operations. The Company will progress the project to Front-End Engineering Design (FEED) and complete associated marketing and financing agreements and can upgrade the study to an AACE Class 2 FEL4 bankable engineering estimation standard in time.
Working capital of US$30M covers the capital required to fund the operation for less than +90-day payment terms. Sustaining and deferred capital is $100M, which allows for mining, maintenance of essential infrastructure and tailings storage facility expansion and refinery maintenance.

REVENUES
Price expectations for the KNP are based upon market intelligence, details of which can be found in press and or in publications, whether printed or on the internet. Examples of such press include Asian Metal, Argus, Platts and CRU Price Services or other websites where pricing is relevant. Price expectations can be expected to vary as market dynamics change in the lead up to production commencing and during the life cycle of the project.
Historically, the prices for niobium have been very stable, having a 20-year period of rising prices and no downside. There is a marginal commodity volatility cycle. Tantalum is subject to greater volatility. Niobium contributes 85% to revenue and Tantalum 15%. Presently, the price outlook for niobium is stable with little or no downside risk and significant upside. The price outlook for tantalum is most likely sustainable but volatile. Utilising the current price of niobium and tantalum as the basis of price expectations is regarded as a base case scenario. Revenues do not consider periods of higher prices typical of a commodity price cycle.

Zircon is a rejected mineral from the concentration process. The zircon produced is elevated in both uranium and iron resulting in an undervalued product with poor marketability. The Kanyika project study is based on stockpiling the zircon for later reprocessing and sale should a viable market emerge.

CASH FLOW
The initial project capital cost estimate (CAPEX) and operating costs (OPEX) estimations for mine plant and processing equipment were prepared and compiled by Wood plc engineers based on inputs from the various subconsultants and Wood plc databases and modified and reviewed by Globe. Orology Mine Consulting undertook mining studies including capital and operating cost estimation.
Valuation methodology uses the net present value and internal rate of return on real costs and revenue. A simple life of consolidated operations cash flow curve based on the project EBITDA is presented below.
==> picture [502 x 266] intentionally omitted <==
SENSITIVITIES
The project economics have a high sensitivity to revenue and operating costs, while being relatively insensitive to CAPEX. The high ratio of operating cost to capital cost means the overall profitably of the mine is reliant on minimising costs and maximising revenues throughout the operational phase.
Major outgoings, particularly in energy purchases and reagents, have a major impact on project value. The effect of revenue is equivalent to reduction in operating cost. The sensitivity to cash flow has a significant impact on the project risk profile and the mine becomes a relatively high economic risk proposition sensitive to variation in commodity pricing, and costs of energy and flotation reagents, leaving the project exposed to pricing fluctuation risks. The price stability of niobium, representing 85% of the project revenue, significantly reduces this risk profile. A significant milestone for the operation is to be connected to a regenerative power system, which would significantly reduce risks associated with diesel supply and power generation cost.

ASSUMPTIONS
The material assumptions to be based on reasonable grounds, there is no certainty that they will prove correct or that the range of outcomes indicated will be achieved.
The material assumptions applied in the Feasibility Study include, but are not limited to, the following:
| Financing: | To achieve the range of outcomes outlined in the Study, funding in the order |
|---|---|
| of US$350M over the life of the Project, inclusive of working capital, is likely | |
| to be required. Investors should note that there is no certainty that Globe will | |
| be able to raise that amount of funding when needed. It is also possible that | |
| such funding may only be available on terms that are dilutive or otherwise | |
| affect Globe’s existing shares. | |
| Currency and exchange rates: | Cost estimates are made in United States dollars. Where the cost is |
| denominated in a foreign currency they have been converted on exchange | |
| rates current at July 2020. Costs denominated in currencies other than United | |
| States dollars account for less than 10% of overall costs. | |
| Capital costs: | Capital estimates have been based on quoted budget prices or known factors |
| and industry standard unit costs provided predominantly by specialist | |
| suppliers as well as current knowledge and industry experience where | |
| applicable. | |
| Revenue factors: | The study assumes a base price of US$55/kg for Nb2O5and US$410/kg for |
| Ta2O5$55/kg mostly as Tantalum K-Salts and that all product manufactured | |
| by Globe is sold. | |
| Operating costs: | Mining costs are based on industry standard unit rates. Processing operating |
| cost estimates are from industry standard unit rates, and first principles. | |
| Transport and shipping costs are based on industry standard unit rates. | |
| Power, gas and water costs are based on industry standard rates, and first | |
| principles. | |
| Royalties and taxes: | Royalties payable to the Malawi government and to the Kanyika community |
| are in accordance with Malawi legislation. Taxes payable to the Malawi | |
| government are based on projected profits and the rates applicable as set out | |
| in Malawi tax legislation. | |
| Market assessment: | Whilst the international market for niobium is based on individual supplier |
| vendor negotiations, Globe staff and its industry specialist advisors have a | |
| good understanding of market volumes and prices and this information has | |
| been used in the Study. | |
| Economic: | A financial model of the Project has been prepared by Globe using input |
| factors outlined herein. The model shows the Project is comfortably | |
| economically viable with a low initial capex, short payback, high NPV and high | |
| IRR. A discount rate of 8% to 16% has been used in the NPV analysis, and the | |
| inflation rate has been assumed at 0%, with fixed costs and product prices | |
| through LOM. Sensitivity of the Project to changes in the key drivers of sales | |
| prices, operating costs (mining and processing costs) was carried out and | |
| showed the Project NPV to be most sensitive to significant changes in sales | |
| prices. The Study uses both a pre-tax and after-tax basis, and a 100% Project | |
| basis for the financial assessment. |

RISK
The project has certain risks with mitigation required in several key areas. The main sources of risks are associated with operations, marketing and location. A non-exhaustive list of key areas is summarised below:
-
Technical risk due to the relatively complex nature of processing.
-
- Located in a relatively remote area in a country with minimal mining experience.
-
Operating cost very sensitive to energy.
-
Requires a technically competent workforce and extensive training of local workforce.
-
Aggressive acid and flammable liquids used in the refinery requires a highly specialised and technically competent personnel working in a highly automated operating environment (staff requirement are low).
-
Sovereign and social risk due to the large, long term Investment in a country with a limited history of mining:
-
Social risks associated with a potentially agitated local community with significant influence of NonGovernment Organisations (NGO’s) resistant to mining projects,
-
Slow Government and poorly coordinated bureaucratic processes; and
-
Community unrest and legal contention,
-
GlobalEdge (2020) country risk rating of “D” equating to “High Risk” for political and economic conditions and a very difficult business environment,
-
GlobalEdge (2020) Business Climate Risk of “D” equating to “High Risk” where the legal system makes debt collection unpredictable, institutional frameworks has serious weakness, and intercompany and interdepartmental government management is difficult to manage.
-
The GlobalEdge (2020) corruption index is 123 out of 198 and ease of doing business is 136 out of 161.
-
Marketing and Revenue Risk:
-
the products are bouquet specialty metals that lack market transparency.
-
a few (3) dominant players in the niobium industry with little known market dynamics.
-
the niobium market is a small market at about 100,000 tonne per annum (tpa), and the project will produce about ~2.5% of global demand and is unlikely to impact price; and
-
the tantalum market is a small market of about 2,200 tpa and KNP will produce up to 5% of global demand. It is unlikely that this will impact price, but lithium producers that have tantalum concentrate by-products are likely in time to create oversupply in the concentrate market.
STRATEGIC DEVELOPMENT
The Company has made the judgement that because of practical, technical, and logistical factors, as well as the lack of any advanced chemical industries in Malawi, the mine site will be the location for the production of pyrochlore (niobium and tantalum bearing) concentrate to be transported and processed at a refinery proximal to an advanced chemical manufacturing facility where highly skilled technical staff can be sourced globally.

MINE TENURE
The Company applied for a mining license (designated AML0026) within the original exploration licence area of the original EPL1008. The conversion of AML0026 to a mining licence (ML) occurred on 13 August 2021 with the grant of a Large-Scale Mining Licence No. LML0216/21 by the Honourable Rashid Abdul Gaffar, Minister of Mines, pursuant to the Mines and Minerals Act (Act No.8 of 2019) – see Appendix B.
Coordinates for the licence area are listed below under ARC1950 grid coordinate system.

MINE PROJECT SETTING
The site is serviced by a 29 km gravel road which accesses the main Malawian M1 highway at the trading centre of Chatoloma. The M1 provides good, fully sealed road access north to Tanzania and on to Dar es Salaam, or south through the capital of Lilongwe and on to Mozambique and Southern Africa. Dar es Salaam (Tanzania) and Nacala (Mozambique) are likely to be the principal ports of export and import, although significant trade directly with other neighbouring countries, especially the Republic of South Africa is anticipated. The location of Kanyika and the principal transport corridors is presented below.
The mine is located at 1,050 mASL approximately 60 kilometres to the west of Lake Malawi. After climbing the escarpment from the lake, the topography is moderate with small hills and incised streams and river valleys. The area surrounding the mine is generally flatter with a more undulating topography but interspersed with hills and bluffs. The area is well populated with extensive subsistence level agriculture and domestic cattle, chickens and goats and limited commercial cropping.
Mineralisation is orientated N-S along a low-lying ridge and extends across the Milenje River in the northern section and the Kanyika River in the south. Drainage flows towards the Milenje River cutting into the topography on the western and eastern sides of the mine area. The most prominent topographical feature in the area is Mphunju, a hill located approximately 5 km east of the ore body at a height of about 1,225 mASL.

Project Access and Transport Corridors
The area experiences a sub-tropical climate, which is relatively dry and strongly seasonal. The warm-wet season stretches from November to April, during which 95% of the annual precipitation occurs. A cool, dry winter season extends from May to August, and frost may occur in isolated areas in June and July. A hot, dry season lasts typically during September and October. The annual average rainfall, based on several stations in the Kasungu area since 1974, is about 800 mm.
Most of the mine envelope is located in degraded miombo-type woodland areas that have been extensively disturbed through various land use activities, most significantly by cultivation, harvesting of timber and grazing by livestock. Evidence of wood harvesting suggests a long history of deforestation. The area is broadly described as low, open canopy and scrub vegetation.
Malawi is within a seismically active belt of the East African Rift System and is characterised by moderate magnitude earthquakes (M ≤ 6.0). Historical records show minor earthquakes reported in various parts of the country, but no damage to property or loss of life had been recorded since the 2009 Karonga earthquake, in which four people died.

PROJECT GENERAL ARRANGEMENT
The following development criteria were used to establish the layout:
-
Mining will be carried out using open cut, drill and blast strategies and material haulage distances will be minimised. The access ramp will exit the pit to the east close to the plant and stockpiles.
-
A blasting safety zone of minimum 500 metres will be demarked.
-
The Milenje River passes through the northern portion of the ore body and will be diverted to the north to accommodate the mining operation.
-
Ore will be crushed, with grinding occurring in an initial semi-autogenous mill and subsequently in a ball mill at a throughput rate of 1.5 mtpa. The material will be beneficiated by magnetic separation and flotation beneficiation to produce a mineral concentrate.
-
The operation is a net water consumer. Hydrogeological and hydrological investigations have indicated groundwater resources in the granite host rock are insufficient, and surface water storage is necessary. An integrated river diversion and water storage facility will be constructed to the west of the pit on the confluence of the Milenje and Chimwa Rivers. Water will be directed around the pit in a diversion channel to re-join the existing river channel downstream.
-
Topography around the target mineralisation is generally undulating and elevated at about 1,050Masl. Ground conditions are generally favourable with up to 10-20 metre of competent clay-materials over bedrock.
-
The operations area will be fenced for safety and security. Villagers currently living in the area will be relocated when notice is provided (no notice has been provided).
-
The site layout was optimised to minimise civil works and maximise utilisation of natural materials and topography for the main project structures, including:
-
Tailings Storage Facility
-
Process plant
-
Pollution containment structures.
-
The prevailing wind is an easterly. To mitigate impact to the communities along Entandweni – Kanyika village axis, all development has been kept to the East of the pit thus allowing maximum buffer zones for abatement issues.
-
A bund wall of mined waste to the west of the open pit will be progressively built to abate noise downwind of operations.

CULTURAL CONTEXT
The Company will work closely with Government and Traditional Authorities (TA) to facilitate the relocation and resettlement of people within the mine area when it is appropriate to do so.
Kanyika inhabitants are mostly Christian-faith subsistence farmers with a preponderance of Ngoni people in the North and Chewa people to the south of the mine site. The mine area is in the Mzimba District and administered from Mzimba approximately 90 km to the north. The town of Kasungu, 55 km to the south-west is the regional and administrative centre of the Kasungu district. The predominant language of the area is Thumbuka and English is spoken by many people.
The mine site is administered under Traditional Authority delegated to the seven group village heads (GVHs) of Yobe Nhlane, Mberebere Ngwenya, Sotchangala, Chidyaki Sibande, Chinkhwagwa, Chombwe and Chibandauka. All this fall under Inkosi Mabulabo’s administrative area. The administrative control of the mine area resides with the District Commissioner resident in Mzimba.
Relocation and Resettlement
The Company has undertaken social, cultural and archaeological studies of the mining area to establish the scope and cost of the relocation activities required to prepare the area for construction and operations. All persons residing within the relocation area, defined within an exclusion zone surrounding the mine, will require relocation.
A census was undertaken by the Company and followed up with a detailed census conducted by the Malawian Department of Lands, in co-operation with the Mzimba District Commissioner’s office and the TA. These data together have been used to nominate the total relocation area which encompasses approximately 250 homesteads with an estimated total of about 1,400 people. The Company has prepared a relocation policy which was submitted as part of an Environmental and Social Impact Assessment (ESIA). Since the publication of the ESIA changes in Malawian legislation will result in a different process for relocation. The framework drafted considers the policy and commitments to be made by the Company in implementing the resettlement and the relocation plan sets out the detailed action plan and responsibilities for implementation of the resettlement process.
The relocation plan details the background of the resettlement area including a description of the affected area, land tenure and an initial description of the assets requiring relocation. It provides the legal framework for land acquisition, compensation and resettlement, and provides guiding principles and commitments by the Company for resettlement preparation and implementation. The relocation plan will culminate in an agreement with the affected persons to be resettled including the compensation required. The Company will ensure that in this process the rights of the affected persons are not compromised, and that compensation is fair to all persons.
Graveyards and Heritage
In accordance with the Malawi Monuments Act, 9th August 1965, a Heritage and Cultural Impact Assessment (HIA) was completed on the area enclosed by the mine fence. Features of high and medium heritage value include the remnants of 3 Iron Age smelting sites and an early Iron Age settlement which identified and these sites will be relocated to a community accessible location or preserved in-situ.
There are 7 recognized graveyards within the proposed relocation area and numerous individual gravesites. A cemetery is positioned on the actual resource and will be moved prior to commencement of mining. The Company commissioned a preliminary survey of gravesites by Mlambe Consulting of Malawi, and the Malawian Department of Antiquities (MDA) has been engaged to prepare a detailed inventory of graves and a relocation strategy. The MDA will manage the actual relocation of those graves that are exhumed for relocation which will only occur late in project implementation after extensive community consultations.

GEOLOGY
The Kanyika deposit is orientated in a N-S direction, is steeply dipping, and is open to the north and to the south. The deposit lies on the western flank of a regional fold associated with an alkali granite which can be traced for about 15 km and is several hundred meters wide.
The intrusion appears to be divided into two planar units separated by biotite-rich rock and;
-
contains pyrochlore and zircon mineralisation in disseminated zones;

has niobium and tantalum mineralization occurring within the mineral pyrochlore, with negligible tantalum minerals such as tantalite and microlite. Pyrochlore appears typically as a disseminated and a relatively non-metamict (absence of crystalline destruction) form within the alkaline granite, as well as in clustered aggregates forming centimetre wide bands; and
-
high-grade mineralisation features pyrochlore bands associated with euhedral centimetre size zircon crystals. Generally, zircon is not always directly associated with pyrochlore.
The Kanyika deposit is hosted within a NNE striking, westerly dipping, fractionated, grey-white, alkali granite in concordance with the surrounding biotite gneiss. The alkali granite crops out cover a strike length of 3.5 km with an average width of 200 m in the south and 50 m in the north.
The figure below displays an isometric 3D view of the intrusion together with drill-holes. The purple solid represents the intrusion model obtained from drill-hole information. The actual granite extends further in all directions, at depth and both to the north and to the south. The model boundaries to the south and north are respectively N8595150 and N8597250. The mineralised host generally dips to the west.

MINERAL RESOURCE ESTIMATE
The Company has completed two resource drilling campaigns reported in 2010 and 2012. Mr Michael Job of Quantitative Group was responsible for preparation and is the Competent Person for the 2012 Mineral Resource Estimate (MRE) as defined by the 2004 JORC Code. Mr Alistair Stephens, a Fellow of the Australasian Institute of Mining and Metallurgy and Mr Andrew Bewsher, a Member of the Australian Institute of Geoscientists, are subsequently responsible for the preparation and are the Competent Persons for the Mineral Resource Statement in 2018 as meeting the requirement of the 2012 JORC code.
The mineral resource reported above a 1500 ppm Nb2O5 cut-off and above a 3000 ppm Nb2O5 cut-off, are shown in the tables below.

Four mineralised zones have been modelled in this resource estimate, over a strike length of 2.25 kilometres represented below.
-
The Milenje Zone (red) is the northernmost and most extensive. This zone extends 2,200 metres from 5200 mN to 7400 mN along a NNE strike direction and remains open to the north.
-
The Entandweni Zone (orange) is located just west of the Milenje Zone and forms the hanging wall mineralised zone of the eastern sheet-like granitoid unit and is open to the south.
-
The Pangano Zone (green), is located on the western side of the central section of the deposit, and has an overall NNE strike. Uzambazi and Pangano Zones (from east to west) together make up the central/southern area.
-
The Uzambazi Zone (yellow) lies parallel to the Pangano Zone and forms the footwall mineralised zone of the western sheet-like granitoid unit and remains open to the south.
==> picture [427 x 198] intentionally omitted <==
Kanyika Mineralised Zones (Oblique long section)
Based on the outcomes from geological logging, examination and the subsequent testwork, Kanyika mineralisation has been classified into 3 vertical domains, based generally on degree of apparent oxidation:
-
Saprock comprised of decomposed saprolite (rock and fines) is generally homogenous across the mineralised body and usually constitutes no more than the upper 5m of the horizon, (up to 10 m).
-
Transition materials can be extensive. The unit can exhibit considerable variation in oxidation from weak to moderate and be distinguished on the degree of competency.
-
Fresh rock is characterized by a lack of oxidation. The rock is generally competent, highly siliceous with distinct veining of pyrochlore and zircon.
There are several sub-domains within each classification, including biotite, amphibolite and variable zircon. Some samples also exhibit hematite and goethite and other minor minerals. Typically, pyrochlore mineralisation remains constant through each domain and throughout the resource. The mineral particle size decreases moving from Milenjie to Uzambazi and the degree of pyrochlore compositing increases.

METALLURGY
Research and development-focused test work was undertaken to understand the metallurgy of the Kanyika mineralisation and thereby provide a technological foundation for development of the ensuing processing flowsheet. The Kanyika mineralisation is unique and not analogous to other niobium-tantalum projects and therefore the extensive effort has been focused to devise a process scheme suitable for a commercially favourable outcome.
The concentrator will produce a pyrochlore concentrate bearing niobium and tantalum.
The key steps in the devised Kanyika project metallurgical process are as follows:
-
a) Comminution (crushing and grinding) to a p80 size of ~106 µm (approx. 100% material below 175 µm) to liberate pyrochlore mineralisation,
-
b) Magnetic separation to remove gangue components and upgrade the pyrochlore,
-
c) Combination of flotation and magnetic beneficiation to further concentrate the pyrochlore concentrate such that it is suitable for transport and processing.
-
d) Filtration, drying and product packaging.
The Company undertook its own internal test work program for magnetic separation and developed a magnetic separation circuit that allowed rejection of waste material with minimal losses of Nb and Ta.
The optimisation program consisted largely of batch and locked-cycle flotation tests and focused on an organic acid reagent-based flotation scheme. Lock cycle tests for recovery-grade outcomes have been undertaken. The results demonstrated that the concentrate grade and niobium pentoxide (Nb2O5) recovery were approximately ~30% and 76% respectively, over a wide variety of samples.
MINING OPERATIONS
Ore production rates will ramp up from 1.0 Mtpa in the first year to 1.5 Mtpa (million tonne per annum) with the life-of-mine stripping ratio to average 1.54:1 (waste : ore). The final open pit dimensions are expected to be in the order of 250 m wide, 2.2 km long (north-south) and average 130 m deep.
Drill and Blast
Rock fragmentation will be undertaken by drilling and blasting based on the rock characteristics obtained during geotechnical drilling investigation. Weathered material makes up about 5% of the total ore material, therefore it is assumed that drill and blast will be used for all material types. It is anticipated that there will be minimal or no water issues for drilling and blasting controls.
A 500-metre blast exclusion zone will be maintained around the pit, with no permanently occupied residences or facilities within the zone. Approximately 250 tonnes of high-energy fuel (HEF) emulsion or ammonium nitrate (AN) will be stored in silos within a fenced compound along with magazines for packaged explosives, initiation devices and blasting accessories. Construction of the magazines will meet the criteria as specified in the Malawian Explosives Act (Cap 14:09) Subsidiary Legislation: Explosives Regulations, Part III: Construction of Magazines (Government of Malawi, 1986). Secondary movements will also occur with placement of waste rock as engineering fill in the tailing storage facility and for other engineering works.
18
==> picture [119 x 44] intentionally omitted <==
Load and Haul
Mining will involve the extraction of ore from several open pits from along a single longitudinal strike at a rate of +1.5 Mtpa mill feed, using conventional open pit methods; drill and blast followed by excavation and load and haul activities. The mining fleet will consist of hydraulic excavators, off-highway dump trucks, and standard open pit drilling and auxiliary equipment. All waste will be stockpiled in a dedicated waste dump to the southeast of the pit.
Process mill-feed and waste will be transported from the pit to either the Run of Mine (ROM) pad for immediate processing, or the low-grade stockpile for later re-handling and processing, and to the waste rock storage dump. During the early years of operation, low grade mill feed will be stockpiled adjacent to the ROM pad to maximise the high-grade feed at the start of operations. A dedicated network of haul roads will be built to separate light vehicles from the haul trucks. The roads will be graded and watered to mitigate dust generation.
Mill feed will be hauled to a single ROM pad located adjacent to the process plant and due east of the pit, with the bulk of the waste dumped to the south east of the main pit. There will be two stockpiling areas. One of the stockpiles will be adjacent to the waste dump and after depletion will be re-designated a waste dump. The arrangement of the main features of the mining program is shown below.
==> picture [408 x 229] intentionally omitted <==
Mining Infrastructure
Pre-Production and Site Establishment
The mining fleet will mobilise to site in the year prior to commencement of production for the pre-production period prior to when the process plant is commissioned. The mining operations will provide infrastructure including heavy vehicle workshops, explosives magazine, tyre change bay and other services necessary to complete the pre-production scope, establish the haul roads from pit to the ROM pad and waste dumping areas, generate sufficient waste to build any infrastructure items that are required for the operation of the mine, provide waste and low-grade mineralisation for the construction of the ROM pad, and have a stock of mill feed equivalent to about four (4) weeks mill feed ready for commissioning the process plant.

Mine Schedule
The mine production schedule prepared by Orelogy Mining Consultants has been designed to produce 1.5 Mtpa of mill feed (see table below). Higher-grade material is treated initially to improve project economics and lowgrade material is stockpiled and rehandled in later years (overpage).

ORE RESERVE ESTIMATE
The Company has completed an ore reserve estimate based on modifying factors included in the feasibility report including but not limited to geology, mineralogy, resource estimate, metallurgy, mining, processing, capital costs, operating costs, environmental monitoring and rehabilitation, community, cultural issues, legal environment, marketing, logistics, water supply, power supply, waste disposal, product sales, market value and risk. These modifying factors were used to derive a mining inventory outlined below. Mr Alistair Stephens has been responsible for preparation of the Reserve Estimate and is the Competent Person for the Mineral Reserve Estimate as defined by the 2012 JORC Code.

CONCENTRATION
The operations process flowsheet was developed based on results from the extensive test work conducted on Kanyika mineralisation evaluating a range of beneficiation strategies. The concentrator incorporates conventional integrated crushing and grinding circuit and magnetic separation before using flotation and gravity concentration techniques to produce a pyrochlore concentrate (approximately +30% Nb2O5 and 1.0% Ta2O5). The process technique gives excellent results with mass yields less than 1% for over 75% recovery of niobium and tantalum. The process flow scheme is illustrated in the figure below.
==> picture [370 x 477] intentionally omitted <==
Concentrator Flowsheet Schematic
The concentrator process scheme is comprised of established unit operations and equipment, but with a unique configuration. The magnetic separation circuit is akin to an iron ore beneficiation circuit and the flotation concentration circuit is a relatively conventional oxide flotation scheme with moderate complexity comparable to other niobium producers.
23
==> picture [119 x 44] intentionally omitted <==
The flowsheet includes the following unit operations:
-
primary crushing to -150mm using a conventional Jaw crusher;
-
milling the crushed material in a semi-autogenous grinding – ball mill grinding circuit operating in closed circuit with Derrick screen classifiers. The mill circuit will target a P80 of 106 µm while minimising fines generation and maintaining a tight particle size distribution for optimum beneficiation;
-
the milled product will be treated by magnetic separation to remove magnetite and gangue mineralisation; and
-
the gravity and flotation plant will consist of gravity concentration to scalp coarse pyrochlore and flotation concentration to collect remaining pyrochlore in the form of an upgraded concentrate. The pyrochlore concentrate product is filtered, dried and packaged for shipment, while the tailings stream is thickened to immediately recover plant water and within the circuit, and the thickened paste (inert flotation residue) will be pumped to the tailings storage facility (TSF).
CONCENTRATOR – INTELLECTUAL PROPERTY
In developing the flow sheet for the concentrator process, various proprietary intellectual property was developed. The key areas of IP coverage are:
-
The flotation scheme for beneficiating pyrochlore mineralisation. This was devised in the course of testing and optimisation work undertaken at GIRCU. The scheme was patented (Patent No. AP 5248) and is held by Globe’s IP holding company.
-
A second highly confidential application has been lodged for an alternative process that reduces the environmental footprint of the project. Details will be released in due course.
TRANSPORTATION OF CONCENTRATE
The operation has been configured to produce a concentrate that is to be packaged and then shipped in sea containers from site to a port on the east coast of Africa.
==> picture [416 x 270] intentionally omitted <==
Transport Corridor Schematic
24
==> picture [119 x 44] intentionally omitted <==
The transportation of unpackaged (bulk loaded) concentrate in small volumes is not cost effective, and higher risk compared to product packed and stored into sea containers. In addition, containerised materials are widely used and are easy to handle and pose little threat of containment loss (eliminates dust emanation). The mineral concentrate product is a radioactive NORM (Naturally Occurring Radioactive Material) material and will classify as a Class 7 for transportation purposes. The packaged and containerised product will have no occupational radiation exposure risk. Transportation of packaged concentrate will require licencing permits to be issued for cross border purposes.
WASTE MANAGEMENT
Management of mining and process waste is a critical part of the mine with several significant post-operational, environmental, social and legacy issues to be managed. The operation will generate a number of residue products and where possible the materials will be recycled within the operation or within the community. The main waste management strategies to be employed are:
-
The tailings storage facility (TSF) will comprise a conventional soil-lined (low permeability) impoundment formed with an embankment constructed from mine waste located in the East of the Milenje Valley and designed in compliance with the ANCOLD[3] and ICOLD[4] standards.
-
The mine waste rock dump will contain approximately 53 million tonne of waste rock from operations. The waste rock has very low to negligible acid drainage potential and is not expected to provide a containment problem, however as best-practice run-off will be contained, and captured.
-
Domestic, medical and other waste will be stored in a conventional landfill and medical and selected industrial wastes will be burnt according to Incineration of Waste (Directive 2000/76/EC).
-
Recycling. Where possible materials from operations will be recycled.
The operations’ TSF is a critical part of the mine with several post-operational and potential legacy issues. A detailed options study was completed during the feasibility period and several potential sites were evaluated before selection.
The operation will produce approximately 33.4 million tonnes of inert tailings over the operating mine life. The solids will be placed in a separate TSF located to the east of the mineralised body. The tailings will comprise flotation tailings, and minor contributions from other areas of the plant. The tailings will be combined and thickened in a thickener before pumping to the TSF for deposition. Process water will be reclaimed from the TSF and pumped back to the plant process water pond for re-use in the process. The tailings have been assessed as non-acid forming and acid drainage or secondary leaching from the tails will not occur. The general arrangement of the TSF is shown below. It should be noted TSF Cell1 is capable of storing the current life of operations tailings and that TSF Cell2 is a concept should the mine life be extended in the future.

General Arrangement of the Tails Storage Facility
The TSF will be designed to survive a significant seismic event and the Company continues to evaluate the optimum TSF construction methodology. The embankment and starter dyke will be constructed using mine waste rock or borrowed material from within the TSF footprint area. The tailings area will discharge from the crest of the embankment to form a beach. The beach then becomes the foundation for a second perimeter dyke; this process continues as the embankment increases in height. The embankment has an overall downstream slope of 1:2.5 and an upstream slope of 1:1.5. The embankment will reach an ultimate overall height of 53 m constructed in four lifts.
The TSF has been designed in accordance with International Commission on Large Dams (ICOLD) and Australian National Committee on Large Dams (ANCOLD) design standards and guidelines for management and storage of mine tailings and complies with relevant Malawian regulations and standards. Site investigations and options studies indicate that the proposed location for the TSF is suitable. Engineering works within the basin and foundation areas will be required to prepare the facility for storage of tailings. Sufficient quantities of construction materials are anticipated to be available, predominantly from the open pit, but with the option to utilise borrow areas within the TSF basin area as required. To reduce embankment fill quantities the TSF embankments will be constructed using modified centreline methods. The TSF will be rehabilitated and capped with topsoil and revegetated to leave minimal long-term legacy issues.

WATER
The management of the water supply is a key operational and practical issue, governed by a number of important factors:
-
the operations will be a “zero-discharge” site to be designed to contain all discharges for events up to a 1:100 ARI rainfall event. Precipitation levels at that level will ensure no environmental impact occurs due to the high level of dilution that will be experienced;
-
significant water quantities used in processing will result in a negative water balance requiring a net input water supply to operations;
-
the hydro-geology rock types of the Kanyika area is dominantly granite resulting in low productivity aquifers in the immediate area, precluding the use of groundwater, and limiting groundwater ingress into the mining pit for use elsewhere;
-
there is indigenous uranium contamination of the groundwater in the area;
-
downstream users of the Milenje River will be protected from any potential pollutants or disruption of supply during both the construction and operational phases.
-
community social responsibility obligations will be undertaken to provide clean drinking water to various stakeholders especially those affected by the operations;
-
minimisation of all ecological effects and provision of positive impacts; and
-
facilitation of a responsible closure plan at the conclusion of operations.
The estimated overall water consumption is summarised below;
Overall Project Water Consumption
| Area | Consumption (m3/a) |
|---|---|
| Process Roads Watering Potable - CSR Targets Plant potable and consumable Camp domestic Total |
1,500,000 290,000 35,000 34,220 8,900 1,868,000 |
A series of hydrological and hydrogeological studies were carried out by specialist engineering contractors and consultants. The hydrogeological investigations have indicated that the Kanyika groundwater resource will be unable to provide sufficient water and a surface water impoundment or dam will be required, sized to meet the above demands, as well as losses through seepage and evaporation, for the whole of the dry season. The resulting capacity of the reservoir is 2.5 Mm[3] to spillway invert level.
The reservoir footprint is 58 ha at spillway invert level. The footprint will increase during the wet season and vary depending on the inflow from the Milenje. The diversion and dam are designed to contain flows and volumes of water resulting from an ARI[5] event. The existing Entandweni-Kanyika public road will be inundated by the reservoir and is to be rerouted over the crest of the new water storage facility (WSF) embankment. The WSF has been designed in accordance with International Commission on Large Dams (ICOLD) and Australian National

Kanyika Water Storage Facility
FUEL, LUBRICANTS SUPPLY & DISTRIBUTION
Overall diesel fuel consumption will be of the order of 1.7 million litres per annum for mining operations and 0.6 million litres per annum used in ROM pad and light vehicle usage. Fuel will be contained within a custom bonded storage facility (refer below). The fuel will then be issued to contractors and used for on-site operations. A high standard of inventory management will be required.
Diesel and lubricants will be trucked into the mine site with custody transfer occurring at the main fuel depot and stores warehouse. The Company will be the registered importer under a specific Malawian import licence recipient and will transfer fuel to registered internal end users as required. One 1 ML tank will be installed at the mining contractor’s facility, and diesel will be metered into bowsers and fuel trucks. The generator fuel will be metered to the power supply contractor’s tanks. A refuelling truck will also be utilized to provide refuelling to stationary or fixed consumers.

ELECTRICAL POWER
Estimated electrical power demand for the operation is based on the current equipment list indicates an installed electrical load of approximately 10 MW with an operating annual power draw of 80,000 MWh/a and a load of 19.5 MW. The current design and operating strategy include the supply input of all power needs from the Malawian electrical grid.

The Company has conducted a number of investigations to determine the optimum power supply model including the provision of an onsite power generation facility. The operations strategy is currently based on connection to the ESCOM transmission line to source power from the ESCOM grid and provide baseload power supply.
The Company has commenced discussions with third party contractors for regenerative power options as an alternative or supplementary system during development. These schemes are highly viable, and the Company is very confident a regenerative power solution, like solar with battery and diesel back-up, is highly probable.

WORKFORCE
The Company has undertaken to maximise the net benefit of the project to Malawi and a significant component of that undertaking will be to develop the human capital available with a structured human relations (HR) management approach.
Due to the need for skilled mining and processing labour, the operation will likely commence with a significant expatriate workforce where national skills are not available. A clear human resources objective is to reduce the expatriate component as logically as possible and replace selected labour with Malawian nationals in positions related to technology and management.
The overall workforce could potentially total up to 150 directly, 50 indirectly and a significant casual workforce. The workforce will be made up of the following components:
-
up to 150 personnel engaged directly by the Company;
-
up to 50 personnel employed by third party contractors or vendors; and
-
an additional budget allowance has been made to maintain a general local workforce of local peoples as a mobile workforce for low-skilled or semi-skilled “general jobs”. This is seen as necessary to maintain local participation requirements and to provide a pool of progressively trained and conditioned personnel to join the mine site workforce.
INDIRECT SOCIAL IMPACT
The Company has assessed that, using a total directly employed position of 400 people another 10,000 other jobs in Malawi will be generated by indirect association with the mine. In addition, another 30,000 people in the Kanyika community area, as defined in the Mines Act, will benefit from the Community Development Agreement royalty of 0.45%.
SOCIAL RESPONSIBILITY PROGRAMMES
The following programs and plans are developed for implementation:
“ Community Engagement Plan ” is the programme of the kind described at section 300 of the Mining Act, and the plan that provides strategies to conduct awareness programs and grievance mechanisms.

CLOSURE PLANNING AND REHABILITATION
The Company has scoped the plan and cost for sustainable closure of the project to ensure that every reasonable effort has been made to achieve rehabilitation closure objectives that will give effect to the following principles:
-
safety and health of people, flora and faunas are safeguarded from hazards resulting from the decommissioned mining operations;
-
environmental damage or residual environmental impacts are minimised to the extent that they are acceptable to all parties involved;
-
the land is rehabilitated to achieve a condition approximating its natural state or suitable to be handed over as agricultural land (either grazing or crop cultivation);
-
the physical and chemical stability of the remaining structures must be such that risk to the environment through naturally occurring forces is eliminated;
-
mine closure is achieved efficiently, cost effectively, and in compliance with the law;
-
the social impacts resulting from mine closure are managed in such a way that establishment of a socially stable community in line with the principles of sustainable development is facilitated; and
-
the closure plan will be undertaken with community consultation.
The closure plan is at a sufficient stage of development given the current status and long life of the operation and will be updated to a more advanced study during the first five years of operations.
FURTHER TECHNICAL WORK PROGRAMS
Additional work programs are planned prior to construction and include;
-
Front End Engineering Design (FEED) and engineering works leading to updated quotations for construction,
-
Studies for patentable technologies,
-
Regenerative power as a supplementary power system as an alternative to grid power, and
-
Studies for the equipment selection that will be needed to suit customer specification of products in sales contracts.

Risks
Operational: The key operational risk will be the successful operation of the proposed operations that is in part mitigated to some extent in the engineering works undertaken, and in that the process largely uses well proven individual components but subject to variation.
Capital: The capital has been costed within Africa as at 2018 using mostly locally sourced suppliers or engineering databases. It is therefore relevant at the date of publication but needs review during the lump sum turn key request for quotation process. Offtake: Contracts for niobium and tantalum for which binding agreements are not signed; this is critical given that the products provide all of the forecast revenue. The Company is pursuing offtake agreements that is also contingent on the Government of Malawi issuing export licenses.
Financing: Successful financing will rely on offtake agreements for at least part of the forecast pyrochlore concentrate production. The expected up front capital requirement is a major amount of funding for which there are no agreements in place. Permitting: The Company has an incomplete development agreement with the Government of Malawi. Signing this document, that has not yet eventuated, will clear the way for all permitting. Given the work to date the Company does not see obtaining permitting as a key risk, however there is the potential for permitting time frames to be longer than expected.
Market volatility: Mineral commodities are subject to market price volatility that the Company is unable to control unless structured into offtake agreements that the Company does not have.
Cost control: The operating and capital costs are current at the time of publication and subject to variation since the estimate was prepared. In the case of Kanyika there are no equivalent processing operations to benchmark costs against, and, although costs have been accurately calculated from first principals and using established estimation techniques, there may be some uncertainty and may need to be re-estimated prior to project implementation. The costs presented here may vary from those that will be realized when the project enters production.
Environmental, Community, Safety, Political: The project will be subject to these risks but cannot quantify when where or how they will impact operations if at all. No solicitation: Nothing in this document represents a solicitation for services or works to or from individuals, groups, businesses, or any Organisation.

Appendix A
About the Kanyika Niobium Project
The Kanyika Niobium Project is geographically located in central Malawi, approximately 55 kilometres northeast of the regional centre of Kasangu and is secured by Large-Scale Mining Licence No. LML0216/21 (refer Appendix B) which grants the Company security of tenure and the right to mine niobium (Nb), tantalum (Ta), and deleterious uranium (U).
Drilling programs totalling 33.8 kilometres of percussion and core drilling have defined the extent of mineralisation. Structured and progressive engineering studies have resulted in the current (JORC 2012) Mineral Resource Estimate (refer below) and given rise to significant improvements and simplifications in the process flowsheet, from that first imagined.
In addition, Globe has undertaken substantial metallurgical optimisation work and commissioned a pilot plant to demonstrate and further optimise metallurgical processes. Metallurgical optimisations studies have improved recoveries from 62% in 2012 to 75% today, through simple novel patented metallurgical processes.
The Kanyika operations will produce a pyrochlore mineral concentrate that contains both niobium and tantalum in commercially valuable volumes to be shipped to a refinery for advanced processing into high purity materials.
A Mineral Resource Estimate for the Kanyika Niobium Project under the 2012 JORC guidelines was reported to ASX on 11 July 2018, as follows:

| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Sampling techniques |
Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc.). These examples should not be taken as limiting the broad meaning of sampling. |
The sampling of drill cuttings has been carried out on Reverse Circulation (RC) and diamond (D) drilling. All RC drilling used hammers with 5 ¼ or 5” drill bits with samples collected at one metre intervals through a cyclone. The vast majority were dry (< 0.3% being wet) and very few of these wet samples being significantly mineralised. Individual 1m composite samples generated from RC drilling were homogenised by a cyclone on the rig. For drilling campaigns prior to 2010, samples were weighed and then split by a 3-tier riffle splitter at 87.5/12.5 ratio. For the 2010 drilling program samples were passed through a single stage riffle splitter several times until the resultant weight of the split sample was two kilograms. Prior to 2010, diamond drilling was carried out at HQ size, with only one hole reduced to NQ. In the 2012 program the definition drilling was conducted with NQ2 drill bits, with HQ3 drilling reserved for geotechnical and metallurgical drilling. The core was orientated below the weathered and transitional zones. Prior to logging all driller’s core metreage markers were check for errors, core was re-pieced together; recovery was determined for runs between markers; metreage lines were drawn on the core; a continuous line was drawn along bottom-of-hole orientations and photographs of core were taken to facilitate future checking. The core was halved longitudinally by a diamond saw for sampling, which was generally on one metre intervals, although some sampling was **at different intervals to account forgeology. ** |
| Include reference to measures taken to ensure sample representation and the appropriate calibration of any measurement tools or systems used. |
Sampling was carried out under Company protocols and QAQC procedures as per industry best practice. See further details below. |
|
| Aspects of the determination of mineralisation that are Material to the Public Report. In cases where ‘industry standard’ work has been done this would be relatively simple (e.g. ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases, more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information. |
Total count scintillometer readings of the RC large sample bags were routinely taken and recorded in a standardised format, to provide an estimate pyrochlore content (by a relative ratio of uranium content) and prior to sample submission and analysis. |
|
| Drilling techniques |
Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc.) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc.). |
All RC drilling used face sampling hammers with 5 ¼ or 5” drill bits and were collected at one metre intervals through a cyclone. Prior to 2010, diamond drilling was carried out at HQ size, with only one hole reduced to NQ. In the 2012 program the definition drilling was conducted with NQ2 drill bits, with HQ3 drilling reserved for geotechnical and metallurgical drilling. The core was orientated below the weathered and transitional zones. |
| Drill sample recovery |
Method of recording and assessing core and chip sample recoveries and results assessed. |
In general, the RC drill holes were kept dry. The total sample was weighed (before splitting), and the data generated, indicated acceptable sample recoveries below the weathered and transitional zones. With diamond core, prior to logging all driller’s core metreage markers were check for errors, core was re-pieced together; recovery was determined for runs |

| between markers. Much of the core from the weathered and transitional zones (generally 20m to 30m down hole) is **broken but is noted to result withpoor recovery only occasionally. ** |
||
| Measures taken to maximise sample recovery and ensure representative nature of the samples. |
Individual 1m composite samples generated from RC drilling were homogenised by a cyclone on the rig. Prior to 2010, samples were weighed and then split by a 3-tier riffle splitter at 87.5/12.5 ratio. For the 2010 drilling program samples were passed through a single stage riffle splitter several times until the resultant weight of the split sample was about two kilograms. |
|
| Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. |
Sample recovery within the weathered zone at Kanyika was less than the fresh zone where excellent recoveries were possible. All sample material generated from RC drilling was weighed and investigated in terms of recoveries. It was noted that recovery in the fresh zone wasgood and was satisfactory in the weathered zone. |
|
| Logging | Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. |
All drill chips were geologically and geotechnically logged using the Company’s geological logging legend and protocols. Suitable petrology and other laboratory-based mineralogical investigations have been undertaken to support Mineral Resource estimation, mining studies and metallurgical studies. |
| Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc.) photography. |
Logging of RC chips records lithology, mineralogy, texture, oxidation, colour and sample quality. The logging of the diamond core makes observations on the characteristics described above as well as structural measurements of features within the core andgeotechnical discontinuities. |
|
| The total length and percentage of the relevant intersections logged | All holes are logged in full. | |
| Sub-sampling techniques and sample preparation |
If core, whether cut or sawn and whether quarter, half or all core taken. |
The core was halved longitudinally by a diamond saw for sampling, which was typically on one metre intervals, while some sampling was at different intervals to account for geology. A half core was taken for sampling. |
| If non-core, whether riffled, tube sampled, rotary split, etc. and whether sampled wet or dry. |
RC samples are collected through a cyclone and a three tiered (pre 2010) or single tiered splitter (2010). Most samples were kept dry. Wet and damp sample intervals are recorded on geological logs. |
|
| For all sample types, the nature, quality and appropriateness of the sample preparation technique. |
Samples were prepared at the Genalysis Laboratory Services in Johannesburg, South Africa. The entire sample pulverised to 85% passing -75 micron, and a sub-sample of approximately 150g retained. This pulp was air-freighted to Genalysis Perth Laboratory, and assays determined by ICP mass spectrometry following a sodiumperoxide fusion. |
|
| Quality control procedures adopted for all sub-sampling stages to maximise representation of samples. |
The sampling procedures were reviewed by Quantitative Group and it was stated that there were no drilling or recovery factors that might have resulted in sampling biases for RC and diamond drilling. The sampling procedures that were set up and followed have provided samples that adequately represent the drill hole. The choice of (typical) 1 metre sample intervals for the diamond holes provides adequate resolution considering the style of mineralisation and the geometric shape of mineralisation. |
|
| Measures taken to ensure that the sampling is representative of the in-situ material collected, including for instance results for field duplicate/second-half sampling. |
Field duplicates were collected with results captured in the database. | |
| Whether sample sizes are appropriate to the grain size of the material being sampled. |
Sample sizes are considered appropriate to give an indication of mineralisation given the particle size and the preference to keep the sample weight at a targeted 2-3kg mass. |
|
| Quality of assay data and laboratory tests |
The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. |
Samples were prepared at Genalysis (Johannesburg) and analysed at the Genalysis Perth Laboratory. The analytical method used was ICP mass spectrometry following a sodium peroxide fusion. The pertinent elements analysed were Nb, Ta, U and Zr with each reported in elemental ppm. Difficulty in analysing Nb and Ta was noted and is probably due to the concentration of hydrofluoric acid in the final digestion solution and the stability of metal complexes with time. Variable concentrations will affect the ability of the aliquot to retain Nb and Ta for an extended period for some sample matrices, which will result in variable degrees of Nb and Taprecipitation in different samples. |

Total count Scintillometer readings of the large RC bags were routinely taken and used as a field check for geological domains. |
|
| Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established. |
Standards, blanks and field duplicates have been routinely submitted on a ratio of one standard, one blank and one duplicate for every 20 drilled samples. Reference material CAN-1 and CAN-2 were prepared by Ore Research & Exploration Pty Ltd of Melbourne from two 125 kg bulk samples of representative mineralised alkali granitoid from Kanyika. Both standards were certified in a program with ten laboratories, for Nb, Ta, U, and Zr. CAN-1 is certified at 2,237ppm Nb and CAN2 as 7,144ppm Nb. |
|
| Verification of sampling and assaying |
The verification of significant intersections by either independent or alternative company personnel. |
The Company has not undertaken independent assay verification of intersections by independent persons however they have reviewed the geological nature of each domain relative to assay information provided by the Company. Company employed persons have reviewed all relevant materials. Prior to undertaking the Mineral Resource Estimate, further validation was undertaken with several drill holes examined by Quantitative Group to check original data with that exported electronically from the database. A summary of the data checks undertaken is as follows: • Original sample submission sheets with sample numbers and sampled intervals were checked against those in the database. There were no problems identified; • Hand-written geological logging checked against database. There were no problems with the drill holes checked; • Original downhole survey records checked against database. In general, the difference between magnetic and grid azimuth (4.6°) was applied, although some readings have been ‘smoothed’ where the influence of magnetic minerals may have affected the readings. In all instances examined, these corrections are logical; • Updated weathering logging for all holes checked against database output, with no errors; • Drill hole collar locations checked in the field as described above, with no errors; • Bulk density determinations checked, and erroneous values removed as described above. • Original electronic files supplied by the assay laboratory checked against the database. Conversions of elemental assays by the laboratories to oxide values were also validated. The quality assurance data was analysed systematically, and check and balances generated with the laboratory. Re- assaying of batches of samples were undertaken where significant deviation from standards. The comprehensive quality control and quality assurance programme undertaken included the use standards or reference materials, blanks (silica sand) and duplicates inserted. The blanks and standards were supplied with the batches of samples. Some 10g of standard and blanks were being submitted. The laboratory was requested to rifle split coarse reject for a field duplicate in the case of DD samples. The standards were not crushed or milled as they were sufficiently fine grained. Blanks (washed silica sand) were introduced in each batch submitted to the laboratory to provide evidence for contamination in the crushing process and pulverisation stages. Some 10g of blank material was supplied for each blank sample included in the sample batch. Difficulty with finding chemically appropriate commercial standards led Globe to replace the field standards used initially in the 2007 campaign with two custom standards of Kanyika material. |

Criteria JORC Code explanation Commentary CAN-1 and CAN-2 standards were manufactured and certified by Ore Research & Exploration Pty Ltd in February 2008. CAN-1 is a low-grade reference material, and CAN-2 is a high-grade reference material. The two standards were initially provided to Acme for use as routine laboratory standards to be inserted into each batch at their Vancouver facility. In subsequent drilling programs, CAN-1 and CAN-2 were routinely inserted as field standards. Comprehensive umpire assaying studies through independent laboratories were undertaken on both RC and diamond drill core material from the preceding drilling programs.

| All the drill hole collars in the Kanyika project area have been accurately positioned using the prevailing industry standards. Independent checking of drill hole collar locations in the field was undertaken by Quantitative Group in 2010 for ten drill holes by using a hand-held GPS unit. The holes were spaced widely across the project, and all checks using the hand-held GPS unit were within 2 metres of the final surveyed position, with most less than 1 metre different. This is considered acceptable give the precision of the handheld GPS unit used for the checks. Downhole surveying was performed by Globe using an electronic single-shot Reflex instrument up to and including 2010. This device relies on magnetism to determine the drill hole azimuth, so it is affected by magnetic minerals. Because there are few magnetic minerals at Kanyika project, the azimuths should be quite comparable. Anomalous readings were removed or smoothed. For the 2012 drilling program, downhole surveys were completed on all holes using a stacked gyro/gamma system. Readings were taken every 5 metres. The magnetic declination applied ispositive 4.62 degrees. |

| Specification of the grid system used. | Gridprojection is WGS 84(Zone 36S) as at 30 June 2018. | |
| Quality and adequacy of topographic control. | The surveying of drill hole collars by Differential GPS formed part of the topographic control. Supporting this dataset were elevation spot heights determined from satellite remote sensing. |
|
| Data spacing and distribution |
Data spacing for reporting of Exploration Results. | Drill spacing in the main part of the deposit is typically on 50m spaced northing lines, with holes spaced at 40m or less along line with significant areas where the drilling has been on 20m centres on 25m spaced lines. There are areas with the 50m spaced drilling, and two small areas of 100m spaced drilling between some 50m spaced data. Refer Table A. |
| Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. |
The spacing of drill holes within and between drill lines is sufficient to establish the degree of geological and grade continuity for this deposit. |
|
| Whether sample compositing has been applied. | No compositing has been undertaken. | |
| Orientation of data in relation to geological structure |
Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. |
Four mineralised zones have been identified. These strike 020° and dip to the WNW at ~40°-80°. Most of the drill holes defining the mineralisation are inclined -55° to the east. 18 scissor holes were drilled to the west to test downhole continuity. Consequently, the orientation of the sampling relative to the deposit geometry limits bias. |
| If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. |
This is not considered material. It is considered that drilling was appropriately oriented for the known strike and distribution of the mineralisation at Kanyika. |
|
| Sample security | The measures taken to ensure sample security. | Individual plastic bags containing samples were packed in large rice bags and sealed with cable ties. They were transported by four-wheel drive or 3-tonne hired trucks. Samples were delivered to Globe’s Lilongwe office and then to the Department of Mines for inspection and export permits. After inspection the truck travelled to the airport where the samples were offloaded and weighed again at the secure premises of Manica Freight. The samples were then loaded onto the aircraft for transport to Johannesburg and collection by Genalysis. A Company representative was always on hand to oversee the packing, transportation and delivery to Manica Freight. Genalysis (Johannesburg) handled the arrangements forpulps to be delivered to Genalysis Perth. |
| Audits or reviews | The results of any audits or reviews of sampling techniques and data. |
In 2010 Quantitative Group (QG) reviewed all the systems put in place by Globe to ensure representative samples are taken and then assayed as accurately as possible with maximum attention to quality, precision and security throughout the process. All the systems were implemented as described and were considered by QG to be of a good ‘modern’ industry standard. During a due diligence exercise, BMGS reviewed the data and database for the resource estimation. The review noted some spurious assays in legacy datasets but overall these had no significant effect on the resource estimation. |

| Exploration done by other parties |
Acknowledgment and appraisal of exploration by other parties. | From 1966 to 1967, the area was mapped at a scale of 1:250,000 by the Geological Survey of Malawi. Following mapping no work was completed in the area until the UNDP conducted a major airborne radiometric and magnetic survey over most of Malawi, at 1km line spacing, between 1984 and 1985. This survey led to the identification of a uranium and uranium-thorium anomaly, measuring approximately 3km by 1km at Kanyika. |

| Criteria | JORC Code explanation | Commentary |

| A field program to investigate the Kanyika airborne radiometric anomaly was conducted by the Malawi Geological Survey in 1986. A total-count ground radiometric survey was completed over an area of 2 by 0.7km. Areas of high radiometric response correlated to foliated nepheline syenite. A total of 91 soil samples and 21 rock chip samples were taken and analysed for Nb, Zn and Pb. Chemical analyses returned Zn and Pb results that were at or near background. Nb assays up to 1.20% in soils and 0.13% in rocks was detected, although there was a poor correlation with anomalous radiometric zones. The analytical suite did not include U, Zr, Ta or REEs due to limitations on available analytical equipment. Following acquisition of the project by Globe Metals and Mining (Africa) Limited, reconnaissance field programs were initiated in 2006. A total-count ground radiometric survey defined two distinct, 020° striking parallel zones, over 2.5km strike length. Soil and rock-chip sampling showed an associated +100ppm U3O8 soil anomaly (peak 482ppm U3O8) and coincident strong Ta and Nb. Rock-chip samples up to 0.29% U3O8, 7.33% Nb2O5 and 0.63% Ta2O5 were returned. |

| Geology | Deposit type, geological setting and style of mineralisation. | Kanyika is an intrusion-hosted Pyrochlore-Zircon mineralized deposit. It lies within the Malawi Province of the Mozambique Orogenic Belt. It is almost entirely underlain by Precambrian and Lower Palaeozoic Basement Complex, predominantly gneiss metamorphic rocks. Most of the rocks in the region are para-gneiss originating from variable protoliths including pelites, sandstones and limestones. Several granitoid bodies of variable size have intruded the gneiss basement and may have originated wholly or in part by anatexis. A few small concordant bodies of alkaline syenite rocks containing nepheline are also present, including the strike-extensive body which hosts the Kanyika Pyrochlore-Zircon mineralization. Airborne radiometric anomalies and follow-up geochemical sampling programs led to the discovery of the Kanyika deposit. With good surface exposure and abundant drill data, the local geology at Kanyika is well known. The deposit is hosted within a NNE striking, westerly dipping alkaline granitoid, which has broadly concordant contacts with enclosing biotite gneiss. The host unit outcrops over 3.5 km strike length, and averages 200m wide at surface in the south and 50m in the north. Niobium and tantalum mineralization occur as the mineral pyrochlore. The pyrochlore mineralization occurs only within the alkali granitoid, in disseminated form as well as in clustered aggregates forming centimeter wide bands. Within the resource area, four broad mineralisation zones are associated with 2 separate sheets of the alkali granitoid that contain disseminated, pale yellow pyrochlore grains. Each of the four broad mineralized zones appear to correlate broadly to footwall and hangingwall zones of the two granitoid sheets. Higher-grade shoots appear to occur generally at slightly more shallowly dipping orientations and thus have a broadly echelon distribution. Zircon mineralization is associated with pegmatite zones spatially associated with these higher-grade shoots and is commonly, but not always, associated with pyrochlore mineralization in the disseminated and higher-grade forms. |

| Drill hole Information |
A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: ▪ easting and northing of the drill hole collar ▪ elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar ▪ dip and azimuth of the hole ▪ down hole length and interception depth ▪ hole length. If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. |
Refer Table A (attached) for drill survey information Refer Table B (attached) for drill hole assay intercept information |
| Data aggregation methods |
In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually Material and should be stated. |
There has been no exploration data included in this report. Only data relative to drilling and resource determination is stated. |
| Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. |
There has been no aggregation of data. | |
| The assumptions used for any reporting of metal equivalent values should be clearly stated. |
Metal equivalents are not used. | |
| Relationship between mineralisation widths and intercept lengths |
These relationships are particularly important in the reporting of Exploration Results. If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (e.g. ‘down hole length, true width not known’). |
Mineralisation widths in drill core have been modelled into true widths. |
| Diagrams | Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported. These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. |

| Balanced reporting |
Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. |
Data is presented from drilling data as received from analytical laboratories. |
| Other substantive exploration data |
Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. |
Bulk samples have been recovered for metallurgical test work. The location of these pits is recorded in Table A and results incorporated into metallurgical test work outcomes. Mineralogical test work has been undertaken to understand the nature of mineralization, the size of mineral assemblages and the nature of the distribution and associations. Niobium, tantalum and uranium is discretely associated with the mineral pyrochlore and zirconium with zircon minerals (with the absence of uranium). Pyrochlore and zircon are not necessarily mutually associated but commonly occur together. The remaining common gangue mineral assemblages are feldspars and minor quartz, biotite and magnetite. Pyrochlore has a dominant size range from 0.02mm to 0.5mm while zircon typically ranges in size from 0.2mm to 2.5mm and up to 20cm. Metamictisation (crystalline structural degradation) of pyrochlore is constrained due to the relatively young age of the host rock. The mineralogical composition of the Kanyika mineralization is therefore relatively simple and lacks complexity of other mineral assemblages that could interfere in metallurgical processes. Mineralogical assessment of pyrochlore and zircon have also been undertaken in various recovery techniques during metallurgical test work programs. Table 1, Section 3 of this report elaborates on metallurgical test work outcomes; bulk density characteristics: geotechnical characteristics are discussed in the section on mining andgroundwater in the section on environmental issues. |
| Further work | The nature and scale of planned further work (e.g. tests for lateral extensions or depth extensions or large-scale step-out drilling). Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive. |
At this stage no significant exploration or mineral resource development works are planned within EPL0421. The Company has been granted an exploration licence EPL0421/15 that covers an area of 308 KM2 to the east and north of the Kanyika project. Further exploration assessment is under consideration, the details of which will be released in due course. LML0216/21 has been granted as the Mining Licence for the Kanyika project. |

| Database integrity | • Measures taken to ensure that data has not been corrupted by, for example, transcription or keying errors, between its initial collection and its use for Mineral Resource estimation purposes. • Data validation procedures used. |
• All survey, geotechnical, logging and sampling data once collected was entered into a temporary Excel database on the project site and validated. It was then uploaded to an internet Sharefile system to be accessed and downloaded to the Perth database, which at the time was a Datamine Fusion database. In recent times the dataset has been stored in a Microsoft Access database and managed by staff of BMGS. • There is limited authorization to make changes to the database to protect integrity. Computers in the site office were all networked and routinely backed up. In addition, backups were routinely made onto external hard drives. Multiple destination backups are made daily at the Globe server. • Drill hole files generated have been compared against historically equivalent datasets as part of the validation process. |
| Site visits | • Comment on any site visits undertaken by the Competent Person and the outcome of those visits. • If no site visits have been undertaken indicate why this is the case. |
• Nil site visits have been conducted by Andrew Bewsher of BMGS, the Competent Person. • BMGS has only recently been involved in the project. During much of the drilling phase, Quantitative Group had a geologist provide independent oversight of the project. • Mr Michael Job, the Competent Person for the previous mineral resource estimation (JORC 2004) had undertaken site visits • Mr Alistair Stephens, the Competent Person for this mineral resource assessment (JORC 2012) has undertaken site visits. |

• Confidence in (or conversely, the uncertainty of) the geological interpretation of the mineral deposit. • Nature of the data used and of any assumptions made. • The effect, if any, of alternative interpretations on Mineral Resource estimation. • The use of geology in guiding and controlling Mineral Resource estimation. • The factors affecting continuity both of grade and geology. |
• Consistent logging of the lithology has correlated well with resultant assay values. • RC and diamond drilling data has been used in the estimation. • No alternative interpretations have been generated. • Geological logging was utilised for identification of the mineralised units and which in-turn guided the determination of bulk density. • No known factors have been identified to influence grade and/ or geological continuity of the deposit. |
| Dimensions | • The extent and variability of the Mineral Resource expressed as length (along strike or otherwise), plan width, and depth below surface to the upper and lower limits of the Mineral Resource. |
• The total strike length of the Kanyika mineral resource extends 2440 metres. At its widest the breadth of the mineralised system is 135 m. The maximum depth extent is 160m. |
| Estimation and modelling techniques |
• The nature and appropriateness of the estimation technique(s) applied and key assumptions, including treatment of extreme grade values, domaining, interpolation parameters and maximum distance of extrapolation from data points. If a computer assisted estimation method was chosen include a description of computer software and parameters used. • The availability of check estimates, previous estimates and/or mine production records and whether the Mineral Resource estimate takes appropriate account of such data. • The assumptions made regarding recovery of by-products. • Estimation of deleterious elements or other non-grade variables of economic significance(eg sulphurfor acid mine |

Directional variography, pairwise relative variography, correlograms and experimental variograms were generated by Isatis. These determined the nugget is moderate for Nb2O5, Ta2O5 and U3O8, but generally slightly higher for ZrSi04. Ranges are generally in the order of 100-200m although ZrSi04 in high grade shoots is significantly shorter. • Grade estimation was completed via Ordinary Kriging (OK) for all of the mineral domains. Seven domains were created, based on variable grade distribution and orientation of mineralisation. • The Mineral Resource estimates compares favourably with previous estimates. • Block size was determined via a quantitative kriging neighbourhood analysis, using Datamine software.

• Nil assumptions were noted regarding correlation between variables. • The geological interpretation was used to guide the estimation. Boundaries were designated as soft or hard by examining the average grade of the variable on either side of the boundary. If there is a pronounced change in the grade across the boundary then it is designated as a hard boundary. Otherwise a soft boundary is used. • The final estimate for the mineralised lodes and high-grade shoots does not use cut values. However, cut values were used for some of the mineralised waste domain estimated as there are some significant outliers at depth of the footwall. • Visual checks and a series of swath validation plots that spatially compare block grades to raw composite data was used as validation tools. In addition, global comparison of the model estimates against the raw and declustered drill hole sample statistics by domain were reviewed. • The block model consists of a non-regular block size with a primary block size of 10m x 25m x 10m and a minimum block size of 1m x 5m x 1m and then regularised into 5.0m x 12.5m x 2.5m sizes for mining modelling • Nil reconciliation data is available. • No financially significant by-products have been identified however, U308 and ZiSi04 could be considered co-existing and semi-collaborative accompanying elements respectively. • An assessment was made into the potential viability for the recovery of by-products other than niobium and tantalum. The economic assessment using metallurgical test work shows not significant value adding for the production and sale of by-products. • Nil deleterious elements have been identified and the resource is importantly low in antimony a material that is deleterious to some types of niobium products. • Raw data analysis supported with metallurgical testwork indicates they are no impacts of deleterious elements in the production of saleable products. |

| Moisture | • Whether the tonnages are estimated on a dry basis or with natural moisture, and the method of determination of the moisture content. |
• Tonnage has been estimation on a dry basis. Bulk density values are estimated based on the extensive collection of in-situ bulk density measurements. |
| Cut-off parameters |
• The basis of the adopted cut-off grade(s) or quality parameters applied. |
• The Mineral Resource Model is reported using a 1500 ppm Nb2O5 cut-off based on conservative commodity prices and costs: Nb2O5 at $US15/lb, Ta2O5 at $US60/lb, U3O8 at $US60/lb a 70% average recovery and at costs of recovery at US$85/tonne (includes open pit mining, processing to a concentrate and refining to bulk finished products). These input parameters have not been altered from the previous modelling and previous resource statement for consistency and that no significant changes in pricing and costs would affect the global position of the resource model. |
| Mining factors or assumptions |
• Assumptions made regarding possible mining methods, minimum mining dimensions and internal (or, if applicable, external) mining dilution. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider potential mining methods, but the assumptions made regarding mining methods and parameters when estimating Mineral Resources may not always be rigorous.

• A mining consultant was engaged to undertake a first pass assessment of a conceptual open pit using estimations for capital and operating costs for the determination and test of the likelihood of economic extraction. Scenarios were undertaken with mining costs of US$4.43 per (total) tonne mined inclusive of mobilisation and demobilisation, pre- production clearing and stripping, internal road establishment, load and haul, drill and blast, ore handling, dewatering, tailings waste overburden removal, overhead fixed costs and dayworks. Rock bulk density in the range of 2.3 to 2.7 tonne per cubic metre was used dependent on weathering type. • The initial design parameters are based on a mill throughput rate of 1Mtpa in the first year (to account for ramp-up |

Mining assumed a conventional open pit operation with mill feed material hauled to a ROM pad or stockpile and waste hauled to a waste rock dump. All material is to be mined on 2.5m flitches with a blasting bench height of 5.0m. A fleet selection for mine design parameters consisted of 50 tonne articulated trucks and excavators undertaken by a mining contractor with the owner conducting grade control, survey and mine planning functions. • The Company has undertaken extensive geotechnical testwork and uses geotechnical consultants determined parameters for pit wall design as 55 degree batters in the oxide zone, 60 degree batters in the transitional zone and 70 degree batters in fresh rock zone. • Only Measured and Indicated Resources have been used in the assessment of economic parameters and conversion to Ore Reserves. Inferred Resources have been excluded from the mining model. • A mining consultant was used to assess and determine mining dilution. Dilution of 4.3% and mineral zone and recovery of 97% have been incorporated into a mining block model based on the wide geometry of mineralisation that is up to 135m wide in areas. • Geotechnical consultants’ recommendations have been incorporated into geotechnical characteristics used for mine design: the uniaxial compressive strength for oxide was assessed to be very weak, for transitional as weak and for fresh rock as strong. Rock Mass strength for oxide, transitional and fresh rock types are respectively, 29° / 53kPa; 43° / 245kPa; and 50° / 1716kPa • Based on the geotechnical assessment criteria, batter heights are assessed to be 10m and 20m and berm widths of 6m to 15m with inter-ramp slope angles of 40° to 55° |
|
| Metallurgical factors or assumptions |
• The basis for assumptions or predictions regarding metallurgical amenability. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider potential metallurgical methods, but the assumptions regarding metallurgical treatment processes and parameters made when reporting Mineral Resources may not always be rigorous. Where this is the case, this should be reported with an explanation of the basis of the metallurgical assumptions made. |
• Various metallurgical investigations were undertaken to establish the most appropriate process route for recovering niobium and tantalum from Kanyika project mineralisation. The Company determined that the most effective process route was to concentrate the pyrochlore mineral (bearing niobium and tantalum) by flotation. • Regarding beneficiation and concentration processes, extensive bench-scale test-work was undertaken on trench samples, intervals of drill core samples and also test pit samples. This work was supplemented with metallurgical pilot plant testing on a 40-tonne sample of mineralisation taken from test pits at different locations within the mineralised zone. • Metallurgical testing of the mineral concentration scheme has shown that milling to a p80 of 106 µm (which equates to a p100 of 150 µm) is typically required for pyrochlore mineral liberation and effective mineral flotation. Flotation testing has demonstrated the production of a pyrochlore concentrate with grade usually ranging from 25-35% Nb2O5 – typically 30% Nb2O5 and 1% Ta2O5 – with niobium and tantalum recoveries of approximately 75%. The mass yield to concentrate is typically 1%. |
| Environmental factors or assumptions |
• Assumptions made regarding possible waste and process residue disposal options. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider the potential environmental impacts of the mining and processing operation. While at this stage the determination of potential environmental impacts, particularly for agreenfieldsproject, may not always be well |
• The Company has undertaken environmental studies and has certificates for the construction of road access to the project under EIA Certificate No. 41.7.4 and a certificate for the development of the Kanyika Project under Certificate No. 43A.4.5 issued under the Environment Management Act No. 23 of 1996. The project development has certain criteria for compliance that are expected to manageable and achievable. • The site plan includes road access upgrade, a location for the open pit mine, waste dumps of ex-mine material, a |

| Bulk density | • Whether assumed or determined. If assumed, the basis for the assumptions. If determined, the method used, whether wet or dry, the frequency of the measurements, the nature, size and representativeness of the samples. • The bulk density for bulk material must have been measured by methods that adequately account for void spaces (vugs, porosity, etc), moisture and differences between rock and alteration zones within the deposit. • Discuss assumptions for bulk density estimates used in the evaluation process of the different materials. |
Extensive in-situ bulk density measurements were made during drilling campaigns. 619 density measurements across the deposit were used to determine the density for 11 separate domains (inclusive of oxide, transitional and unweathered material). Measurements were taken on <15cm long clean, solid, core billets using an electronic scale accurate to 0.1g. The mass of the dry core billet was measured, then the mass of the core billet suspended in water in the cage below the scale. The relative density was calculated by the formula: RD = Md / (Md – Mw), where Md = weight in air and Mw = weight in water All readings were recorded on paper by a geotechnician and entered into a spreadsheet with handwritten records filed and retained. The scale was checked once a day against calibration weights supplied by the manufacturer. In order to estimate in-situ dry bulk density using relative density measurements the material to be measured must be non-porous. In the case of a weathered or vugg bearing sample, the core was dip into wax prior to measurement. • Determinations were taken every 5-10 metres downhole. 15 cm lengths of core were used, with weights recorded dry and in water. Oxide and porous samples were coated in wax prior to weighing. Samples with outlier values were checked by an independent geologist and removed if appropriate. All discarded results corresponded to samples within the weathered domain. • Bulk density for oxide material is measured to average 2.5 tonne per cubic metre and 2.7 tonne per cubic metre for transitional and unweathered material types. • There are no assumptions for bulk density estimates. |

| Classification | • The basis for the classification of the Mineral Resources into varying confidence categories. • Whether appropriate account has been taken of all relevant factors (ie relative confidence in tonnage/grade estimations, reliability of input data, confidence in continuity of geology and metal values, quality, quantity and distribution of the data). • Whether the result appropriately reflects the Competent Person’s view of the deposit. |
• Resource classification as Measured, Indicated or Inferred is based on drill-hole density. The slope of regression is also used as a guide for determining the classification. Where the drilling is spaced equivalent o or less than 25m x 20m, the classification is Measured. An Indicated classification is based on 50m x 40m drill spacing or less. An Inferred classification is based on 100m drill spacing and down dip extensions. In some places, material has also been classified as Indicated where the drill spacing is at 100m spacing but only relates to one region along strike of 50m spaced drilling in the upper part of the model. This is justified by the fact that where there has been infill drilling (to 50m spaced sections in this area), the interpretation, tonnes and grades have only changed slightly compared to that estimated from the broader spaced drilling. • Data integrity has been analysed and a high level of confidence has been placed on the dataset and resultant resource estimation. • Mr. Andrew Bewsher and Mr. Alistair Stephens retain a high degree of confidence in the result of the resource estimation.

| Discussion of relative accuracy/ confidence |
• Where appropriate a statement of the relative accuracy and confidence level in the Mineral Resource estimate using an approach or procedure deemed appropriate by the Competent Person. For example, the application of statistical or geostatistical procedures to quantify the relative accuracy of the resource within stated confidence limits, or, if such an approach is not deemed appropriate, a qualitative discussion of the factors that could affect the relative accuracy and confidence of the estimate. • The statement should specify whether it relates to global or local estimates, and, if local, state the relevant tonnages, which should be relevant to technical and economic evaluation. Documentation should include assumptions made and the procedures used. • These statements of relative accuracy and confidence of the estimate should be compared with production data, where available. |
• Visual checks and a series of swath validation plots that spatially compare block grades to raw composite data was used as validation tools. In addition, global comparison of the model estimates against the raw and declustered drill hole sample statistics by domain were reviewed. • Bulk sample pits taken validate mineralisation grades and validate recovery assumptions for section of the mineralisation |

| To identify ore and waste within the Kanyika deposit, the block value calculation was applied to all blocks within | |||
| the block model on a block by block basis. If the block value returned is greater than zero, then the block is flagged | |||
| as ore. This method was applied as: | |||
| • Kanyika is multi element deposit, therefore a single COG value cannot be determined, |
|||
| • The cost of concentrate transport is dependent on the block grade for Nb2O5, hence the concentrate |
|||
| transport costs are variable dependent upon feed grade. | |||
| Note: | |||
| 1. the variable costs associated with mining each block is excluded from the above calculations as the |
|||
| variable mining costs are considered as “sunk costs” for COG purposes. | |||
| 2. The optimisation process uses the variable mining costs to determine the shape of the ultimate pit shell, |

| and therefore the blocks can be considered as mined to the pit exit and then the decision toprocessthe | |||
| block or not is applied. | |||
| The two approximate break-even COG’s as shown in the table above are represented by the dashed lines in the | |||

| mineralised material with grades less than the dashed lines that have a combined grade greater than the solid | |||

| for each element individually, this material returns a positive cash-flow when the two elements are combined; |

The increase in slope design parameter is due to a re-interpretation of the rock strength and discontinuity shear strength determined from the new geotechnical data and updates in the modelled geological surfaces. 4) The risk profile of the recommended slope design parameters will be addressed in the report; it is appropriate for a FS level of reliability. 5) The slope design satisfies the limiting constraints i.e. Static case - minimum factor of safety (FOS) of 1.3 and Dynamic case - minimum FOS of 1.0 |

Criteria JORC Code explanation Commentary 6) The berm width design is based on Modified Ritchie's Criterion and the Martin-Piteau method to provide rock fall catch protection and to provide sufficient catch width to retain a bulked failure volume based on the interpreted controlling failure mechanism.
-
7) The inter-ramp slope angle for any given pit wall is measured from crest to crest between haul ramps legs 8) The overall slope angle is measured from the pit crest to the toe of the pit slope.
-
9) The batter slope design assumes batter faces are depressurised for groundwater. The stability of the overall/inter-ramp slope is sensitive to changes in the groundwater assumptions; a partly drained inter-ramp / overall slope has been assumed.
-
10) The stability analyses undertaken to determine the slope design parameters assume good blasting practices are adopted to minimise damage to pit slopes.
-
11) Slope design parameters have been determined for each domain and each weathering class.
-
12) For the transition/Fresh rock mass, the slope design is based on frequency distribution graphs of structure dip and cumulative frequency analyses for assessment of potential planar and wedge failure on foliation/contact/joints structures.
-
13) Diligent batter scaling will need to be employed every mining flitch to ensure that any developing instabilities are adequately addressed.

Waste Dumps
The waste dumps have been designed to the following criteria:
-
End dumping of waste by haul truck with minimal rehandling.
-
Swell factor of 30% (after compaction by traffic of dump trucks),
-
Maximum ex-pit dump height = 50m,
-
Construction lift height for ex-pit dumps = 10m,
-
Final ex-pit dump overall face slope = ~20°;
-
Ramp width = 25.0m and
-
Ramp grade = 1 in 10.
Approximately 20.7 million bcm of mine waste rock will be generated over the LOM. Based on a swell factor of 30%, after dump compaction, a WRD volume of approximately 27 million m³ will be required to store the mine waste rock. Some mine waste rock will be used in the construction of the ROM pad, pit abandonment and acoustic bund and stockpiles platform. No waste backfilling into the pit has been considered at this stage due to any future potential expansion of the mine.

Comminution
The following comminution parameters were quantified for comminution samples, which in turn dictated
sample masses required for testing:
• Grindability parameters – Bond rod mill work index, ball mill work index and abrasion index
• SAG milling amenability – SMC drop weight test
• Rock strength – unconfined compressive strength (UCS)
• True SG.
For the purposes of providing comparative hardness depth, Fresh ore has been arbitrarily sub-classified as
follows:
• “Fresh Upper” From the upper boundary with Transition material to the base of the initial drill holes at
around 40 m
• “Fresh Lower” Reflects hardness within the range 45 to 95 m, only limited sampling undertaken
• “Fresh Deeps” Reflects hardness at depths down to 118 m, only limited sampling undertaken.

Commentary Flotation
The philosophy adopted for sample compositing was similar to the comminution test work in that a measure of variability with oxidation type, with depth and down the length of the orebody, was the objective.
A total of 34 samples were selected from various sections of remaining drill cores (after comminution sample removal) to assess the impact of material variability on flotation. These selections generally corresponded with the fractions of drill cores selected to assess impact of material variability on comminution processes.

| used over the life of the project. Tailings settle rapidly typically within 1 hour of deposition with permeabilities of | ||||
| about 1x10-6 m/s giving rise to rapid release of underdrainage and supernatant. The tailings are non-acid forming | ||||
| with a negative Net Acid Producing Potential (NAPP) and Net Acid Generation (NAG) pH greater than 4.5 (and | ||||

| The Explosives Act (CAP 14.09) governs all aspects of the storage, handling, mixing, preparation and use of | ||
| explosives for blasting. All persons storing, preparing and using explosives must have a licence in terms of Section | ||
| 6 (1) of this Act. | ||
| The Kanyika Project will require exclusive use of land and plans to resettle resident people in the area before | ||
| fencing the area with a security fence for the duration of the project. As such the Company will comply with the | ||
| provisions of relevant Acts to negotiate with stakeholders to secure access to the land. The process of land | ||
| acquisition is compliant with the legislative requirements. The Kanyika Project area is currently classified as | ||
| customary land. | ||
| The Company has prepared a relocation plan to facilitate the re-settlement process. This process requires the | ||
| Company to compensate the Government (that then is provided to the people) for land and the people displaced. | ||
| Communities surrounding the project rely on rivers and community boreholes as the only water sources in the | ||
| area. Although geochemical analyses of mine waste have indicated a limited potential for metal contamination | ||
| from sources at the mine, the precautionary principle is applied where run-off from these areas is contained and | ||
| prevented from entering the environment. This is also important in the containment of sediment loads that are | ||
| detrimental to aquatic life as well as introducing a source of radioactivity into the environment. The monitoring | ||
| of the impact of dewatering on the availability within community boreholes is also required and actions will need | ||
| to be implemented to ensure that no member of the community is left without water. | ||
| The Water Resources Act (Cap 72:03) makes provision for the control, conservation, apportionment and use of | ||
| the water resources of Malawi and for purposes incidental thereto and connected therewith. The control of all | ||
| public water is vested in the Minister, where control will be exercised in accordance with provisions of the Act. | ||
| The following aspects are applicable to the Kanyika Project: | ||
| • Ownership of all public water (groundwater and water found flowing on surface, in rivers, streams, |

| lakes, springs, pans, swamps on private or public land) is vested in the President. | ||
| • Public water may not be dammed, stored, abstracted, diverted or used without a valid water right, |

| As | part of the infrastructure development for the project, the following changes and activities will be carried out | |||
| to | modify existing water resources. Mitigating activities are summarised below. | |||
| • Construction of a water storage facility to the west of the project – which will interrupt the flow of the |
||||
| Milenje River from the confluence of the Chimwa and Milenje Rivers to the junction with the Mthabua. | ||||
| Most of the affected area is within the resettlement zone but there are a small number of affected | ||||
| people between the fence and Mthabua. Globe will undertake the following mitigating strategies: | ||||
| - Maintenance of the water storage facility as a community resource including provision of irrigation |
||||
| facilities, fish stocking of the reservoir. | ||||
| - Reticulated potable water supply to downstream areas which are impacted by the project. |
||||
| - Reticulated potable water supply to community boreholes affected by dewatering operations |
||||
| within the pit. | ||||
| • Construction of the Milenje river diversion around the northern extension of the pit. This will have |
||||
| minimal impact on the amenity of the area but will be constructed to provide an on-going resource at | ||||
| the conclusion of the project. | ||||
| • Dewatering activities within the pit will create localised depletion of the aquifer and reduce flow to two |
||||
| community bores – a new reticulated system will be installed to maintain water supply to the users. | ||||
| The Company’s Community Social Responsibility (CSR) programs will focus on projects with community benefit. | ||||
| Upon completion of the Development Agreement, the Company will commence implementation of a Social | ||||
| Management Plan and Local Business Development Plan to build on the existing Social Impact Assessment which | ||||

| segments (including the ferro-niobium, superalloy and superconductive segments). Other major competitors in | |||
| the niobium market include Magres Niobec Mine and China Molydenum Catalao mine. | |||
| Niobium is listed as a strategic mineral by the EU and USA and the Boston’s Massachusetts Institute of | |||
| Technology (MIT) list it as one of the top ten minerals impacted by new technology. It is a strong metal, highly | |||
| resistant to heat and wear. Due to its relevance in aerospace and defence, Niobium has few or no substitutes | |||
| for the metal’s essential use and is regarded as one of the most highly critical. Supplies are considered | |||
| potentially at risk because only a few sources throughout the world produce the metal. Almost 90% of the | |||
| world supply comes from Brazil and nearly all of that comes from only one mine (Araxa). | |||
| Refractory metal alloys based on niobium find applications in the aerospace industries because of their high | |||
| melting points and high temperature strengths. They are generally produced by powder metallurgy techniques | |||
| due to their very high melting points. Niobium is the lightest refractory metal with a density close to nickel and | |||
| exhibits good thermal conductivity. Niobium can be alloyed to improve high temperature strength and | |||
| oxidation resistance. | |||
| A new emerging market for niobium exists with the development of the Toshiba SCiBTM rechargeable battery | |||
| that uses niobium and titanium (anode) as an ultra-rapid rechargeable lithium ion battery that provides high | |||
| power density, long life, low fire risk. Toshiba claim this to be a “game changing” development and the use is | |||
| proposed for applications that need high energy and rapid recharge like automobiles, buses, railroad cars, | |||
| elevators and power plants, (refer Toshiba press release 3 October 2017: at | |||
| https://www.toshiba.co.jp/about/press/2017_10/pr0301.htm ). | |||
| Tantalum | |||
| The electronics industry is by far the largest tantalum consumer, using tantalum powder and wire in the | |||
| manufacture of capacitors, which are used to store electrical energy in electric circuits. Technology has | |||
| facilitated a shift toward the miniaturization of electronic equipment, which has driven the demand for | |||
| tantalum-based capacitors in space-sensitive and high-end applications, including smartphones and storage | |||
| devices. Superalloys are high-performance alloys that exhibit excellent mechanical strength, resistance to | |||
| thermal creep deformation, strong surface stability and resistance to corrosion or oxidation. These properties | |||
| make them well-suited for use in aerospace applications. | |||
| The tantalum market is mainly comprised of companies that have a high degree of downstream vertical | |||
| integration (i.e. processing and fabrication). Some of these competitors do not mine raw materials, and thus | |||
| source their key inputs as concentrates. Major participants in the tantalum market include Global Advanced | |||
| Minerals Pty Ltd, Advanced Metallurgical Group (Netherlands) CNMC NingXia Orient Group Co Ltd., ULBA | |||
| Metallurgical Plant JSC, a Kazatomprom company in Kazakhstan, and H.C. Starck of Germany. |

| One of the main uses of tantalum is in the production of electronic components. An oxide layer which forms on | ||
| the surface of tantalum can act as an insulating (dielectric) layer. Because tantalum can be used to coat other | ||
| metals with a very thin layer, a high capacitance can be achieved in a small volume. This makes tantalum | ||
| capacitors attractive for portable electronics. | ||
| Tantalum causes no immune response and has found use in the production of surgical implants. It can replace | ||
| bone, it can connect nerves as foil or wire, and as woven gauze it binds abdominal muscle. It is very resistant to | ||
| corrosion and so is used in equipment for handling corrosive materials. It has also used as electrodes for neon | ||
| lights, AC/DC rectifiers and in glass for special lenses. Tantalum alloys can be extremely strong and have been | ||
| used for turbine blades, rocket nozzles and nose caps for supersonic aircraft. Tantalum is a speciality metal that | ||
| is predicted to grow at 3.2% CAGR. Approximately 62% of global supply originates in Africa (DRC, Rwanda, | ||
| Ethiopia). | ||
| Products | ||
| Tantalum and niobium are significant metals that render unique properties to the end products and have low | ||
| substitutability. Resources of tantalum and niobium exist in abundance relative to current consumption and | ||
| therefore, the risk of the geological availability of tantalum and niobium is typically low. The important factors | ||
| that affect the supply and demand of these two metals can be summarised as: | ||
| • Many geological occurrences of niobium are associated with complex mineralogy resulting in difficult |
||
| metallurgical recovery processes and expensive capital and or metamictisation (crystalline structural | ||
| degradation and destruction typically by uranium within the mineral lattice) rendering high grade deposits | ||
| with poor recovery or unrecoverable. Secondary weathering of these also complicates metallurgical | ||
| recovery processes. Careful selection on mineralogy is considered an extremely important metallurgical | ||
| factor. | ||
| • The installed capacity of niobium is not sufficient to meet the projected increases in its demand, and its |
||
| price is therefore expected to increase at a steady pace. | ||
| • The supply of tantalum is under stress and there is a shortage in supply because of the depletion of the |
||
| stockpiles, the cessation of operations in Australia and irregular and uncertain artisanal mining in Africa. | ||
| Tantalum refining bottlenecks are a key impediment to the tantalum supply chain. | ||
| • New lithium mines across the globe, especially Australia, may also have tantalum concentrate by-products. |
||
| An increase and possible oversupply of tantalum concentrates. It is possible that tantalum prices will come | ||
| under backwardation pressure in the future but balanced with tempered reality due to unrealistic | ||
| expectations of tantalum sales from lithium developers. The tantalum industry is refinery constrained and | ||
| no significant impact to refinery product pricing is seen in the market at this stage. | ||
| • The Commodity Supply Risk Index (Herfindahl-Hirschmann Index) for tantalum and niobium is 8,885 (out of |
||
| a scale up to 10,000) and implies that tantalum and niobium have a high supply risk due to the political |
82
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| instability in the producing countries (eg central African tantalum artisanal mines) or for niobium a high | ||
| centration of production to one country but with low political risk. | ||
| • The effectiveness and the performance of the substitute metals are found to be significantly poor and |
||
| therefore, the lack of suitable substitutes increases the supply risk for tantalum and niobium. In some | ||
| application niobium can be substituted for tantalum. | ||
| • The supply of tantalum and niobium is largely dependent on the primary sources as the recycling rate of |
||
| niobium is low at about 10-15% while the recycling rate of tantalum is about 20% (USGS, 2009). | ||
| • The emerging technologies in the electronic industries, especially in transport, will drive additional market |
||
| demand for both tantalum and niobium. By 2030 emerging technologies should increase the demand for | ||
| tantalum by a factor of 2.55 and the demand for niobium is expected to increase by a factor of 3.0. | ||
| Substitution | ||
| Substitution of a metal with other metals in any one of its application sectors can have an impact on the supply | ||
| of the metal. Supply stress in the case of tantalum and niobium can be reduced by substitution in select cases. | ||
| Aluminium and ceramics are substitutes of tantalum in the ceramic industry. Niobium, platinum and titanium | ||
| are used as substitutes for tantalum in corrosion-resistant equipment whereas zirconium, hafnium, iridium, | ||
| molybdenum, rhenium, and tungsten are some substitute metals that can be used in the high temperature | ||
| applications. Low alloy steels, molybdenum and vanadium are substitutes of niobium; titanium for tantalum in | ||
| stainless steel; and ceramics, molybdenum, tantalum and tungsten in high-temperature applications. However, | ||
| in each case the substitute is significantly poorer in quality. | ||
| Recycling | ||
| Recycling is a secondary source of tantalum and niobium. Data for the rate of recycling of niobium are not | ||
| available but are estimated to be about 10%-15% while the recycling rate of tantalum is about 20% (USGS, | ||
| 2009). Primary ores remain the largest source of tantalum and niobium supply at 80% and 85%-90%, | ||
| respectively (USGS, 2009) and therefore recycling as a source of metal for both tantalum and niobium currently | ||
| may have limited impacts. | ||
| Economic Significance | ||
| The availability of a metal that has high supply risk, and high economic importance is critical. In a study | ||
| prepared for the European Commission (2017), tantalum and niobium are determined to be critical elements | ||
| for the EU, and possibly Britain and the USA. The relative usage of niobium in Russia, India and China is | ||
| significantly below the global average, and while not assessed in the European Commission, logic would | ||
| determine that significant economic benefits and productivity could be realised by additional supply into these | ||
| countries. |

| Impact of Existing Technology A comparison between notebooks manufactured in 2003 and 2005 showed a changing trend in the use of capacitors away from the use of tantalum MnO2, tantalum polymer, and aluminium polymer capacitor technologies. The share of aluminium polymer capacitors had reduced from 14% in 2003 to 4% in 2005 while the share of tantalum MnO2 capacitors in PC notebooks had decreased from about 39% in 2003 to 25% in 2005. The replacement by more efficient tantalum polymer and niobium oxide capacitors increased market share from 47% in 2003 to about 70% in 2005. New materials are always being used to either replace rare materials or substitute for a superior material. The history suggests that there will always be impacts from changes to and replacement of materials in existing technology. Impact of Emerging Technology The supply of raw materials needs to be capable in meeting demand for emerging technological innovations to have effect. A study commissioned by the German Federal Ministry of Economics and Technology (BMWi) in 2010 on the raw materials including tantalum and niobium were studied in the fields of emerging technologies in micro capacitors, medical technology and ferroalloys. The demand from emerging technologies in 2030 is estimated to change by a factor of 3 for niobium (circa 180,000 tonne per annum) and by a factor of approximately 2.55 for tantalum (circa 3000 tonne per annum). The projected increase in demand for tantalum and niobium due to emerging technologies highlights the importance of the need for a secure supply network and that restricts supply will have an impact on technological growth. The impact of both existing and emerging technologies on the demand for tantalum and niobium, further stresses the importance of a steady supply that must be able to meet their changing demand levels. Demand level fluctuates with technological innovations and changes, and therefore the availability of the raw materials should also be sufficiently elastic to satisfy the demand at the right time. Impact of emerging Market Niobium trials as an additive to aluminium has demonstrated a 30% reduction in weight for no loss of strength of aluminium metals. The material has sound castablilty, lower porosity, increased mechanical properties, and better homogeneity. Use of niobium in the aluminium industry could substantially increase demand. Supply Analysis The supply of niobium is constrained to three operating mines and with growth demands of CAGR of about 8- 12%. Tantalum supply is highly diversified and low-cost supply from many alluvial mines in central Africa, however some of these Africa sources are designated as conflict minerals. Kanyika is low grade compared to other deposits but has two product revenue streams of niobium and tantalum, that help its competitiveness as well as higher recovery due to the mineralogical state of pyrochlore. Other niobium deposits are strategically interesting projects as sources of niobium, however some are in difficult legally and/or political situations and others are high capital costs. Tantalum concentrate supplies are likely to increase in volume and put downward pressure on price as new lithium mines look to market low grade tantalum concentrate by-products. |

VALMIN CODE 2015 Valuation Procedure
Effective 1 July 2016, it is a condition in the valuation of mineral assets or project valuations that the VALMIN Code (2015) (publication dated 30 January 2016) is used (effective 1 July 2016) for public reporting of technical assessments and valuations of mineral assets (prepared by the VALMIN Committee a joint committee for the AUSIMM and AIG). Under the VALMIN Code (2015), this report recognises consistency with Section 1 Introduction, Section 2 VALMIN Practitioners and complies with the following: Section 3 Code Principles of Competence, Materiality and Transparency and Section 4 of Reasonableness and Independence, Section 7 Technical Assessment, Section 8 Valuation, Section 9 Financial Modelling, Section 10 Risk and Opportunities, Section 11 Other, and Section 12 Declarations. Under Section 6, Commissioning a Public Report, the Company commissioned SRK Consulting (Johannesburg) to assist, prepare and report an independent valuation assessment. The Company complies with the methodology of Section 5, Public Reporting, and the Company

| applicable to Malawi and broad assumptions on deductible depreciation rates | ||||
| Profit after tax forecast is an estimate. Depreciation allowances in Malawi include a straight-line depreciation | ||||
| over the life of operations on non-saleable capital items and a 20% rate of diminishing value on saleable capital | ||||
| items as a broad approach to the Malawian Tax Act (2006). Globe’s financial model does not include an | ||||
| accurate depreciation schedule as a pre-production model can only broadly estimate the depreciation rates on | ||||
| taxable income. This in no way would account for the detail amortisation and depreciation schedules that | ||||
| would be implemented during operations. A profit forecast is therefore not an accurate reflection of profit | ||||
| during operations.. | ||||
| The | project valuation is based upon the following key assumptions: | |||
o |
Sales Volumes: it is assumed that the following volumes of finished product >99% quality can be sold: | |||
| - Nb2O5 3,250 tpa on average life of mine |
||||
| - Ta2O5 140 tpa on average life of mine |
||||
| Note: the projected sales of Nb2O5 represent less than 5% of global production. | ||||
o |
Pricing: it is assumed that the finished product +99% quality can be sold at the following prices (CIF Chinese or | |||
| European port) and discounted as a concentrate to market price in line with market practice. | ||||

Legal Action The Company and the Government of Malawi are currently defending in the High Court of Malawi an action by the local community who allege that mining has commenced and claim the defence has breached their constitutional rights by preventing rights to land and lifestyle and a claim for compensation, damages and resettlement. At this stage, in discussion with the community, the Company has a high degree of confidence that the court proceedings will not continue and that a settlement with mutual benefit will be forthcoming. The issue of a mining licence primarily solves the community claim for action on development, relocation and resettlement. Exploitation Pre-requisites The exploitation of the deposit is dependent on: • A signed Mine Development Agreement with the Government of Malawi • A Community Development Agreement on royalty payments governed by the Mines Act • An agreement on compensation and resettlement of affected persons, • Product Sales contracts, • Project Funding, • Board approval for a “decision to mine”, • Contracts for construction, development, operations and supply of materials. Risk Globe’s activities, as in any business, are subject to risks which may impact upon Globe’s business and future financial performance, and there can be no guarantee that Globe will achieve its stated objectives. While some risks can be mitigated by the use of safeguards and appropriate systems and actions, some are outside the control of Globe and cannot be mitigated. |

|---|---|---|---|
| Existing shareholders in Globe and potential investors should review announcements made by Globe to ASX (at | |||
| www.globemm.com or atwww.asx.com.au under the code “GBE”) in order to gain an appreciation of Globe’s | |||
| activities, operations, financial position, plans, prospects and opportunities. | |||
| This report does not make any opinion on securities however an investment in Globe’s securities should be | |||
| considered speculative. Securities carry no guarantee with respect to the payment of dividends, returns of | |||
| capital or the market value of those Securities. There are specific risks which relate directly to Globe’s business. | |||
| In addition, there are other general risks, many of which are largely beyond the control of Globe and its Directors. | |||
| The risks identified in this section, or other risk factors, may have a material impact on the financial performance | |||
| of Globe or its or financial condition and the market price of Globe’s securities. | |||
| The following is not intended to be an exhaustive list of the risk factors to which Globe is exposed. | |||
| 1.2 | Company specific | ||
| (a) Limited history | |||
| Globe has no operating history in terms of mining and refining and has limited historical performance. | |||
| Further, Globe has operated at a loss since its incorporation. No assurance can be given that Globe will | |||
| achieve profitability nor derive acceptable returns through the operation of the Kanyika Project. | |||
| Achievement of Globe’s objectives will depend on Globe’s ability to successfully implement its strategy. | |||
| There can be no assurance that Globe will be successful in implementing its strategy or that Globe will | |||
| be able to anticipate or meet the needs of the market generally. If Globe is unable to implement its | |||
| strategy, then there may be adverse effects on its results of operations or financial condition. | |||
| (b) Reliance on Key Personnel | |||
| Globe’s ability to successfully execute its business strategy will depend substantially on the performance | |||
| and expertise of its key personnel and their familiarisation with, and ability to operate, in the mining | |||
| industry as well as technology and marketing in the niobium and tantalum commodity markets. The loss | |||
| of services of one or more key personnel may have an adverse effect on Globe’s business. Furthermore, | |||
| if Globe is unable to attract, train and retain key individuals and other highly skilled employees and | |||
| consultants, the results of its Company’s operations or financial condition may be adversely affected. | |||
| (c) Competitors and new market entrants |
|||
| Globe operates in a competitive global industry. There is always a risk that existing operators could | |||
| expand or extend their operations, or new operators could enter the market, adversely affecting the | |||
| results of Globe’s operations or financial condition. | |||
| (d) Uncertainty of future profitability | |||
| The attainment of future profits is subject to multiple risks, including construction and mining risk, | |||
| financing risk, product risk and Globe’s ability to successfully operate. Further, Globe’s future profitability | |||
| will be impacted by its ability to successfully execute its strategy, economic conditions in the markets in |
94
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| which it operates, competitive factors and regulatory developments. Accordingly, the extent of any | ||
| future profits are uncertain. Moreover, the level of profitability cannot be reliably predicted. | ||
| (e) Commodity prices and exchange rates | ||
| If Globe achieves success leading to mineral production, the revenue it will derive through the sale | ||
| exposes the potential income of Globe to commodity price and exchange rate risks. Commodity prices | ||
| fluctuate and are affected by many factors beyond the control of Globe. Such factors include supply and | ||
| demand fluctuations for commodity prices for niobium and tantalum, technological advancements, | ||
| forward selling activities and other macro-economic factors. | ||
| There can be no assurance that the existing level of metals prices will be maintained in the future. Any | ||
| future declines in metals prices could adversely affect Globe’s business prospects and financial condition. | ||
| Furthermore, international prices of the majority of commodities are denominated in United States | ||
| dollars, whereas the income and expenditure of Globe are and will be taken into account in Australian | ||
| currency, exposing Globe to the fluctuations and volatility of the rate of exchange between the United | ||
| States dollar and the Australian dollar as determined in international markets. In addition, as Globe’s | ||
| Kanyika Project is located in Malawi, capital and operating costs will be incurred in United States dollars | ||
| and Malawi Kwacha. Accordingly, movements in the exchange rate between the Australian dollar and | ||
| the United States dollar and between the United States dollar and the Malawi Kwacha will affect these | ||
| costs. As such, movements in exchange rates may have an impact on Globe’s financial position and | ||
| performance. | ||
| (f) Environment |
||
| Although Globe intends on conducting all activities in an environmentally responsible manner, if it is | ||
| responsible for environmental damage it may incur substantial costs for environmental rehabilitation, | ||
| damage control and losses by third parties resulting from its operations, which may adversely effects the | ||
| results of its operations or financial condition | ||
| (g) Capital costs of construction of Facilities | ||
| Globe’s capital cost forecasts are based on the best available information at that time, independently | ||
| sourced, and certain assumptions in respect of cost and timing of planned development of Facilities, | ||
| receipt of design and development approvals and regulatory approvals, and the level of capital | ||
| expenditure required to undertake planned development and maintenance of the assets. Any significant | ||
| unforeseen increases in the capital costs or delays in receipt of approvals associated with Globe’s | ||
| planned activities may adversely impact its results of operations or financial condition. | ||
| (h) Additional capital requirements | ||
| Globe expects to have sufficient working capital to accelerate its business plan. If Globe incurs | ||
| unexpected costs additional funding may be required. There is no certainty regarding the ability of Globe | ||
| to raise sufficient funds to meet its needs into the future. Globe may need to raise additional capital from |
95
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| equity or debt sources due to unforeseen circumstances. There can be no assurance that Globe will be | ||
| able to raise such capital on favourable terms or at all. If adequate funds are not available on acceptable | ||
| terms Globe may not be able to develop its business and this may have an adverse impact on Globe’s | ||
| operations. | ||
| (i) Contractual disputes |
||
| Globe’s business model is dependent in part on contractual agreements with third parties. Whilst Globe | ||
| will have various contractual rights in the event of non-compliance by a contracting party, no assurance | ||
| can be given that all contracts to which Globe is a party will be fully performed by all contracting parties. | ||
| Additionally, no assurance can be given that is a contracting party does not comply with any contractual | ||
| provision, Globe will be successful in enforcing compliance. There are also counterparty insolvency, | ||
| fraud, management failure, creditor, termination and operational risks. Should a third party contract fail, | ||
| there is the potential for negative financial and brand damage for Globe. | ||
| (j) Litigation risks |
||
| Globe is exposed to possible litigation risks. Further, Globe may be involved in disputes with other parties | ||
| (including but not limited to customers, third party providers, business partners or employees) in the | ||
| future which may result in litigation. Any such claim or dispute if proven, may impact adversely on | ||
| Globe’s operations, financial performance and financial position. Globe is not currently engaged in any | ||
| litigation. | ||
| (k) Force majeure | ||
| Globe’s operations now or in the future may be adversely affected by risks outside the control of Globe | ||
| including labour unrest, civil disorder, war, subversive activities or sabotage, fires, floods, explosions or | ||
| other catastrophes, epidemics or quarantine restrictions. | ||
| (l) Doing business outside of Australia |
||
| Globe’s Kanyika Project is located in Malawi. For operational reasons Globe may also establish | ||
| operations in other jurisdictions. Wherever Globe sets up operations Globe is exposed to a range of multi- | ||
| jurisdictional risks such as risks relating to currency exchange rates, labour practices, environmental | ||
| matters, difficulty in enforcing contracts, changes to or uncertainty in the relevant legal and regulatory | ||
| regime (including in relation to taxation and foreign investment and practices of government and | ||
| regulatory authorities) and other issues in foreign jurisdictions in which Globe operates. Businesses that | ||
| operate across multiple jurisdictions face additional complexities from the unique business requirements | ||
| in each jurisdiction. Management experience will help to mitigate, but will not remove, this risk. | ||
| (m) Change in regulatory requirements | ||
| Globe is required to comply with laws, including the laws governing its operations, privacy, taxation and | ||
| business practices in each jurisdiction in which it operates. Globe may be subject to other laws in | ||
| jurisdictions in which it plans to operate, and the applicable laws may change from time to time. Globe’s | ||
| Kanyika Project is located in Malawi and is subject to the laws of Malawi. There is a risk that new laws |
96
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| and regulations in Malawi may be introduced or existing laws and regulations may be amended, or that | ||
| the regulator may form a different view to its current view at a future date. Any failure or perceived | ||
| failure by Globe to comply with laws, regulations, policies, legal obligations or industry standards may | ||
| result in governmental enforcement actions and investigations, including fines and penalties, | ||
| enforcement orders. Litigation and/or adverse publicity could cause suppliers, customers to lose trust in | ||
| Globe, which could have an adverse effect on Globe’s reputation and business. | ||
| (n) Mining Licence | ||
| The Kanyika Project’s mining licence in Malawi is subject to the laws and regulations of that jurisdiction. | ||
| Globe must therefore comply with all requirements under the relevant laws (including mining legislation) | ||
| of Malawi and comply with all licensing conditions. There is no assurance that the Government of Malawi | ||
| will not make material changes to laws that impact the mining licence, or that approvals or renewals will | ||
| be given as a matter of course or on similar economic terms. There is also additional risk that changes | ||
| to government policy could occur that could materially and adversely affect Globe’s rights and costs | ||
| associated with holding its mining licence. | ||
| (o) Community relations | ||
| Globe’s ability to undertake mining activities at the Kanyika Project will depend in part on its ability to | ||
| maintain good relations with the relevant local communities in Malawi. Any failure to adequately | ||
| manage community expectations in relation to land access, mining activity, employment opportunities, | ||
| impact on environment and local businesses and any other expectations may lead to disputes, | ||
| disruptions which may adversely impact Globe’s results of operations or financial condition. | ||
| (p) Sovereign risk | ||
| Malawi is a developing country and Globe’s operations in the country are subject to numerous risks | ||
| associated with operating in a developing country. These include economic, social and political | ||
| instability, changes of laws affecting foreign ownership, government participation, taxation, and | ||
| repatriation of income or return of capital. These risks may adversely impact Globe’s results of | ||
| operations or financial condition. | ||
| (q) Commodities superseded by new technology or changes in business practices | ||
| Globe’s business is based largely on the future sale of niobium and tantalum. Niobium is predominantly | ||
| used in the manufacture of steels and tantalum in various chemical, medical and steel applications (refer | ||
| marketing section). There is a risk that the demand for niobium or tantalum could decline or be displaced. | ||
| (r) Protection and ownership of intellectual property |
||
| Globe’s financial performance may depend on its ability to safeguard and commercially exploit its | ||
| intellectual property. Globe relies on patents to protect its proprietary intellectual property. A | ||
| substantial part of Globe’s commercial success will depend on its ability to maintain, establish, and | ||
| protect its intellectualproperty and operate without infringing theproprietary rights of thirdparties. |
97
| Criteria | JORC Code explanation | Commentary | Commentary |
|---|---|---|---|
| (s) Concentration of shareholding and liquidity |
|||
| At the time of this publication, Globe’s major shareholder holds approximately 53% of Globe’s total | |||
| issued share capital and is represented on the Board by Ms Alice Wong, Chairperson, and is in a position | |||
| to exert significant influence over matters in relation to Globe, including the strategic direction, | |||
| operations, funding, election of directors, the appointment of new management and matters submitted | |||
| for a vote to Shareholders. There is a risk that the interests of the existing major shareholder may be | |||
| different from the interests of current holders and potential investors in Globe. | |||
| (t) No market sector diversification |
|||
| Globe’s business is entirely exposed to the mining sector and specifically to the performance of the | |||
| Kanyika Project in Malawi. Globe’s results of operations or financial condition may be adversely affected | |||
| if the Kanyika Project does not perform as planned or expected. | |||
| 1.3 | Industry specific | ||
| (a) Resource and Reserve Estimations |
|||
| Globe has made estimates of its resources and reserves based on relevant reporting codes, where | |||
| required, and judgements based on knowledge, skills and industry experience. However, there is no | |||
| guarantee that estimates will prove to be accurate. Actual mining results may materially differ from | |||
| forecasts and estimates due to further findings and results not previously known or fluctuations in | |||
| operating costs, exchange rates and metal prices. | |||
| (b) Construction inherent risks |
|||
| If Globe is ultimately successful in obtaining the required funding achieving production at the Kanyika | |||
| Project The building of the Facilities, involving specialist mining plant and infrastructure, involves | |||
| significant risks and hazards which are inherent in construction, including, cost overrun, time overrun, | |||
| engineering design defects, faulty workmanship, personal injury or death. Globe will engage specialists | |||
| in relation to design, construction, equipment supply, installation, commissioning and operation of the | |||
| facilities. There is a risk that one or more of these third-party contractors will not perform its contractual | |||
| obligations properly or at all. Weather conditions are unpredictable and may also have a material | |||
| adverse effect on construction of the facilities, including on the delivery of supplies, equipment and fuel. | |||
| Should Globe experience a significant risk or hazard whilst building the facilities, Globe’s results of | |||
| operations or financial condition may be adversely impacted. | |||
| (c) Mining inherent risks |
|||
| If Globe is ultimately successful in achieving production at the Kanyika Project, its operations will be | |||
| subject to risks and hazards inherent in the mining industry. The development of mineral deposits |
98
| Criteria | JORC Code explanation | Commentary | Commentary |
|---|---|---|---|
| involves significant risks, including environmental hazards, industrial accidents, metallurgical | |||
| performance and variability, other processing problems, unusual or unexpected rock formations, | |||
| structure collapses or slides, flooding, fires and interruption due to hazardous weather conditions or | |||
| diseases. These risks could result in damage to, or destruction of, mineral properties, production facilities | |||
| or other properties, personal injury or death, environmental damage, delays in mining, increased | |||
| production costs, monetary losses and possible legal liability which would, were they to occur, likely | |||
| impact Globe’s business and financial performance. | |||
| (d) Insurance |
|||
| Globe seeks to maintain appropriate policies of insurance consistent with those customarily carried by | |||
| organisations in its industry sector. Insurance of all risks associated with Globe’s business may not always | |||
| be available and where available, the cost may be prohibitive. Any increase in the cost of the insurance | |||
| policies of Globe or the industry in which it operates could adversely affect Globe’s business, financial | |||
| condition and operational results. Globe’s insurance coverage may also be inadequate to cover losses it | |||
| sustains. Uninsured loss or a loss in excess of Globe’s insured limits could adversely affect Globe’s | |||
| business, financial condition and operational results. | |||
| 1.4 | General securities investment and market risks | ||
| (a) Economic risk |
|||
| General economic conditions in Australia, Malawi and internationally, movements in rates of | |||
| interest, inflation and currency exchange, variations in commodity prices, the global security | |||
| situation and the possibility of terrorist disturbances, changes to government regulation, policy or | |||
| legislation, changes which may occur to the taxation of companies as a result of changes in | |||
| Australian, Malawian and foreign taxation laws may have an adverse effect on Globe’s business | |||
| activities and future financial performance, and its ability to fund its activities. | |||
| (b) Market conditions |
|||
| Share market conditions may affect the value of Globe’s quoted securities regardless of Globe’s | |||
| operating performance. Share market conditions are affected by many factors such as: | |||
| • general economic outlook; |
|||
| • introduction of tax reform or other new legislation; |
|||
| • interest rate and inflation rate; |
|||
| • commodity price fluctuations; |
|||
| • changes in investor sentiment towards particular market sectors; |
|||
| • changes in financial outcomes estimated by securities analysts; |
|||
| • the demand for, and supply of, capital; |
|||
| • terrorism or other hostilities; and |
|||
| • other events or factors which may be beyond Globe’s control. |

| Criteria | JORC Code explanation | Commentary | |
|---|---|---|---|
| The market price of securities can fall as well as rise and may be subject to varied and unpredictable | |||
| influences on the market for equities and in particular, resources stocks. Neither Globe nor the | |||
| Directors warrant the future performance of Globe or any return on an investment in Globe. | |||
| (c) | Security investments | ||
| Investors should be aware that there are risks associated with any securities investment. | |||
| Securities listed on the stock market, and in particular securities of mining and exploration | |||
| companies have experienced extreme price and volume fluctuations that have often been | |||
| unrelated to the operating performance of such companies. These factors may materially | |||
| affect the market price of Globe’s securities regardless of Globe’s performance. | |||
| (d) | Liquidity risks | ||
| There may be relatively few buyers and sellers of securities on ASX at any given time. This may | |||
| affect the volatility of the market price of the securities and the prevailing market price at | |||
| which holders are able to sell their securities. This may result in holders receiving a market | |||
| price for their securities that is less or more than the price originally paid. | |||
| (e) | Speculative Nature of Investment | ||
| The above list of risk factors ought not to be taken as exhaustive of the risks faced by Globe or | |||
| by investors in Globe. The above factors, and others not specifically referred to above, may in | |||
| the future materially affect the financial performance of Globe and the value of Globe’s | |||
| securities trading on ASX. Globe cannot, and does not, provide any guarantee with respect to | |||
| the payment of dividends, returns of capital or the market value of its securities. Existing | |||
| holders and potential investors should consider that an investment in Globe s speculative and | |||
| should consult their professional advisers before making any decision. | |||
| (f) | Community and Indigenous Title Risks | ||
| It is also possible that, in relation to tenements which the Company has an interest in or will | |||
| in the future acquire such an interest, there may be areas over which legitimate law of native | |||
| title rights of peoples exist. If native title rights do exist, the ability of the Company to gain | |||
| access to tenements (through obtaining consent of any relevant landowner), or to progress | |||
| from the exploration phase to the development and mining phases of operations may be | |||
| affected. The Directors closely monitor the potential effect of native title rights involving | |||
| tenements in which the Company has or may have an interest. | |||
| (g) | Other | ||
| Other risk factors include those normally found in conducting business, including litigation | |||
| through breach of agreements or in relation to employees (through personal injuries, | |||
| industrial matters or otherwise) or any other cause, strikes, lockouts, loss of service of key |

| Audits or reviews • The results of any audits or reviews of Ore Reserve estimates. |
The Company has had the mining resource model and project operating and capital costs reviewed and compiled by independent professional firms and believes that this independence qualifies as satisfactory audits. SRK Consulting (Johannesburg) were engaged to provide and independent opinion of the feasibility study. There has been no independent review of the product marketing environment, but marketing material has been sourced by independent publications. A list of the companies participating in the feasibility study are listed below.
