Resolute Mining Limited (ASX/LSE: RSG) (Resolute or the Company) is pleased to announce an updated Mineral Resource Estimate and ongoing exploration success at Tabakoroni which has enabled the completion of a Pre-Feasibility Study (PFS or the Study) to assess the potential for a new underground gold mine at Tabakoroni to augment gold production from the Company's Syama Gold Mine in Mali (Syama).
The Tabakoroni Mineral Resource has been upgraded to 7.4 million tonnes (Mt) at 4.4 grams per tonne (g/t) gold (Au) at a 1.5g/t Au cut off for a total of 1.04 million ounces (Moz), an increase of 22% over the previous estimate (see ASX Announcement dated 29 April 2019). The Study has established a mining schedule, consisting of Indicated and Inferred Resources, of 2.4Mt at 4.9g/t containing 387koz (see Note 1 below). Gold production is expected to average approximately 80,000oz per annum over an initial four-year mine life. The All-In Sustaining Cost (AISC) is calculated to be US$974/oz. The Tabakoroni underground deposit remains open both along strike and at depth and ongoing exploration success is expected to expand Mineral Resources and extend mine life.
Managing Director and CEO, Mr John Welborn, welcomed the Study, which provides support for the ambition of establishing underground operations at Tabakoroni which will enable total production from Syama to be sustained at approximately 250koz per annum going forward:
"Tabakoroni has been a highly successful Syama satellite open pit oxide mining operation for Resolute, producing approximately 400,000 ounces of gold over the past three years. We expect our ongoing exploration success and feasibility studies will confirm a future underground operation at Tabakoroni."
"Exploration and evaluation of the Tabakoroni underground mine potential will continue during the remainder of 2020 and into 2021. The timeline on development is supported by our contemporaneous exploration efforts to define further surface oxide mineralisation. We now have more than 500,000 ounces of oxide resources from in ground satellite deposits and oxide ore stockpiles. Our immediate ambition is to use this oxide material, and further satellite oxide resource targets we are exploring, to maintain our Syama oxide production going forward at approximately 80,000 ounces per annum."
"The Tabakoroni underground Study provides confidence that we will be able to transition current Syama Oxide gold production, based on Syama satellite open pit mining, to similar annual levels of production based on a Tabakoroni underground operation. Further detail on our plans for Syama will be published in an updated Syama Life-of-Mine plan which will be completed during the current quarter."

1 Note that the Mining Inventory of 2.4Mt at 4.9g/t contains both Indicated (54%) and Inferred (46%) Mineral Resources. 46% of the production target ounces referred to in this document is based on Inferred Mineral Resources. There is a lower level of geological confidence associated with Inferred Mineral Resources and there is no certainty that further exploration work will result in the determination of indicated mineral resources or that the production target itself will be realised.

Updated Tabakoroni Underground Mineral Resource Estimate
Geology and Mineralisation
Gold mineralisation at Tabakoroni is hosted within the 5 to 25m thick Tabakoroni Main Shear Zone (TMSZ), a brittleductile shear zone developed in carbonaceous shale and siltstone rocks and localised along the eastern margin of Syama Formation basalt-dolerite flows and interflow sediments. The TMSZ gold mineralisation is associated with pyritic and carbonaceous fault gouge. Adjacent sandstone and siliceous siltstone display stockwork quartz-carbonate veins with pyrite disseminated throughout. Stylolitic quartz reefs are developed along the length of the TMSZ.
Drilling to date has identified high grade gold mineralisation over a strike length of 1.8km with better gold grades seen where the shear intersects the basalt sediment contact. North of the Namakan pit the basalt is absent in the hanging wall and better grades are associated with felsic porphyry intrusives within the TMSZ.
Resource Estimation and Classification
Resolute published the maiden underground resource at Tabakoroni on 29 April 2019 comprising 5.2Mt @ 5.1g/t Au for 850,000oz. Since that time diamond drilling has continued uninterrupted with the focus on infill and extensional drilling to increase the confidence in the geological model and to improve continuity in the mineralisation. Interim results from this drilling was reported on 12 December 2019 with numerous high-grade intersections confirming the width and grade of the underground mineralisation. The drilling program was completed to a nominal drill density of 50m and the resource was subsequently re-estimated in the second quarter of 2020.
The underground resource at Tabakoroni was updated to underpin the Study. The resource was estimated by wireframe constrained Ordinary Kriged (OK) methodology, as used in the previous estimate in April 2019.

Table 1: Tabakoroni Underground Mineral Resources
Mineralisation wireframes for underground were created with a cut-off grade of 1.5 g/t Au with a minimum downhole thickness of 2m. Five domains have been identified at Tabakoroni. The main domain is the TMSZ which is a steeply dipping shear mineralised over 1.8km of strike. A second domain was created for the parallel lodes adjacent to the TMSZ, and there are a number of shear-parallel smaller lodes. Another domain was created for the shallow westerlydipping lodes in the southern portion of the deposit. These lodes are dipping at 45° and appear to overprint the TMSZ. A further domain created was the steeply dipping mineralisation in the north-eastern portion of the deposit, which strikes at 20° to the northeast. The final domain is referred to as Namakan Deeps which are shallow westerly-dipping lodes in the central portion of the deposit. These lodes appear to be veins with significant presence of arsenopyrite.
Gold, sulphide sulphur, organic carbon and arsenic was estimated into a three-dimensional block model using OK methodology with dynamic anisotropy to account for the undulating nature of main shear zone.
Top cutting was required to reduce the influence of outlier values. Variograms were generated for the mineralised 1 metre composites. Optiro carried out kriging neighbourhood analysis based upon the gold variograms to optimise the estimation parameters, and these parameters were used for ordinary kriging into the 5m x 10m x 5m parent cells.
Density was assigned based on weathering codes; 2,190 measurements were taken from diamond hole samples. These measurements suggested a density of 2.72g/m3 for the fresh, 2.38g/m3 for the transitional material and 2.12g/m3 for the oxide material.
The estimation was validated and then classified as Measured, Indicated and Inferred in accordance with the JORC Code (2012) reporting guidelines. The default classification for the mineralisation is an Inferred Mineral Resource. Measured Mineral Resources are defined by contiguous zones where the nominal drillhole density is 12.5m by 12.5m, while an Indicated Mineral Resource has been defined by zones where the nominal drillhole density is around 25m by 25m. The resource has been depleted for mining as of 31 March 2020.
Study Outcomes
The Study incorporates the updated underground Mineral Resource and multiple technical studies. The Study estimates include all capital and operating expenditure and royalties over the proposed Life-of-Mine plan (LOM). Ore mined comprises Indicated and Inferred Mineral Resources (See Note 1). Project capital is estimated to be US$118 million (m) with estimated start-up capital of US$86m. Project capital includes US$20.4m for conversion of the current Syama Oxide processing plant to also process sulphide material (retains the ability to process oxide material in the event of further exploration success) and US$12.6m for a new paste plant, power and underground infrastructure for the underground operation at the Tabakoroni site. All existing open pit infrastructure will be repurposed for the underground. Underground mining and ore haulage to the processing plant at Syama is planned to be undertaken by a contractor similar to current practice at Syama and Tabakoroni open pits, further diminishing the initial capital requirement and ensuring prompt access to ore.

Project Summary
Location
Tabakoroni is located within the Finkolo Permit, 35km south of the Syama Gold Mine (Syama) processing plant in southern Mali (refer to Figure 3). Tabakoroni is connected to Syama via a purpose-built all-weather unsealed haul road.

Figure 3: Tabakoroni project location map

History
Resolute completed the acquisition of the Finkolo Permit in April 2018 (see ASX Announcement dated 25 May 2018). Resolute's initial exploration focus at Tabakoroni was on identifying oxide resources. Open pit operations commenced at Tabakoroni in late 2018 with high grade oxide and transitional material currently being mined and processed through the 1.5Mtpa Syama oxide circuit. To date open pit operations at Tabakoroni have delivered 3.8 million tonnes of ore at 2.4g/t containing 288koz of recovered gold.
Resolute published a maiden underground resource for Tabakoroni on 29 April 2018. An internal conceptual study was completed in 2019 to identify areas of interest for further infill drilling, as well as extensional drilling. Drilling continued during 2019 and 2020, resulting in an updated underground resource model to support the Study.
Scope of the Study
The objectives of the Study included the following:
- Deliver PFS in September 2020 on Tabakoroni Underground potential
- Replace oxide gold production (~80 koz Au per year)
- Confirm a viable mine plan (mining method, design and schedule)
- Confirm an initial mine life (~ 5 years inventory)
- Confirm a reliable processing option (flow sheet, design and recovery)
- Consider the impact on all stakeholders (environmental, social, security, etc)

Key Study Elements
Mining
The Study identified long hole open stoping (LHOS) mining methods as the most suitable to the style of mineralisation and geotechnical conditions. A trade-off study of various underground methods was undertaken, and the selected mining methods were:
• The main mining method will be LHOS with cemented paste backfill. This method was applied to the TMSZ in the Northern Zone, and upper parts of the Namakan Zone where the mineralisation is 4m to 15m wide and near vertical. Preliminary test work conducted on Syama tailings and the highly weathered Tabakoroni open pit oxide waste indicated that both sources can successfully be used to make a cemented paste fill.

• In the western hangingwall of the Namakan Zone narrower (2m to 6m wide) and shallower dipping (45° to 60°) mineralisation parallel to the TMSZ are located in good ground conditions and lends itself to open stoping with pillars without fill.
The mine design covers a strike length of over 1km, located primarily below the Tabakoroni Namakan and North pits as shown in Figure 4. New surface infrastructure requirements are kept to the minimum by reutilising the current open pit infrastructure and positioning the portal in the Namakan Pit to avoid extensive box cutting through the weathered overburden layer. New infrastructure is limited to a new power plant for the underground (obsolete generators will be relocated from Syama as part of the Syama Power Plant upgrade project), a paste plant, a surface explosive magazine and some minor infrastructure modifications and additions to the existing open pit infrastructure as required for underground mining.

Figure 4: Tabakoroni surface infrastructure general arrangement
Primary stoping focuses on the ore located between 60,100mN and 61,000mN (local grid). Due to the strike length of the design and two higher grade zones naturally forming below the North Pit (Northern Zone) and Namakan Pit (Namakan Zone) respectively, two declines will be developed. The Northern Decline serves a strike length of approximately 300m of ore and the Namakan Decline approximately 600m strike length of ore. The planned mine design is shown in long-section in Figure 5.
Development dimensions have been designed to suit the selected equipment and expected geotechnical conditions. Declines will be 5.5m W x 5.8m H, positioned in the more competent basalt rock to the west and suitable in size for 55t to 63t trucks. Lateral development requiring truck access will have dimensions of 5.5m W x 5.5m H, and 4.5m W x 4.5m H in the ore drives. A 20m vertical level spacing was selected to ensure good ground control during drilling and blasting, especially in the shallower dipping stopes. Drill rigs capable of drilling 89mm diameter blastholes were selected.
Mine design was performed using Deswik Mineable Shape Optimiser (MSO) at a cut-off grade of 3.0 g/t Au. Geotechnical modelling identified ground conditions ranging from poor to good, for both hangingwall and footwall conditions. Modelled stope dilution of 0.5m (good) to 2.0m (poor) were included into the MSO analysis for each domain and separated for hangingwall and footwall based on modelled conditions. Maximum stope lengths were estimated at 10m to 50 m based on ground conditions. However, scheduling was done on maximum stope lengths of 20m until final grade control drilling can confirm localised ground conditions. Isolated stopes and sub-economic levels were removed, and sub-economic internal stopes were left insitu as regional support pillars. Declines were
positioned to provide early ore access, while taking potential future expansion into account as the mineralisation is still open both along strike and at depth.

Figure 5: Tabakoroni long section of mine design (looking east)
A detailed Deswik schedule was constructed to schedule development, production drilling, stoping and backfill. The following schedule priorities and sequence were then applied:
- Establish portal in Namakan Open Pit
- Develop decline access and primary ventilation on 270 mRL
- Develop the connection decline to connect North Zone and Namakan Zone, and connect paste fill lines and primary services networks from surface
- Develop Namakan Decline and North Decline independently. Some early opportunistic stoping is possible below South Pit
- Develop ore drives on each level to economic limits and retreat stoping back to level access in a top-down sequence
- Paste fill each stope prior to mining the next stope. Where mining conditions allow, mine stopes as open stopes without fill
- Figure 7 and Table 4 show a steady state production rate of 650ktpa to 750ktpa (160kt to 180kt per quarter).
Figures 6 to 8 illustrate the development schedule over the LOM, the anticipated ore production schedule and gold mined and recovered. It should be noted that Year 6 Quarter 1 in the production schedule consists of only one month's production and should not be viewed as a full quarter's production. Further mine plan optimisation programs and exploration success could alter the mine plan and could provide some investment upside.

1 Note that the Mining Inventory of 2.4Mt at 4.9g/t contains both Indicated (54%) and Inferred (46%) Mineral Resources. 46% of the production target ounces referred to in this document is based on Inferred Mineral Resources. There is a low level of geological confidence associated with Inferred Mineral Resources and there is no certainty that further exploration work will result in the determination of indicated mineral resources or that the production target itself will be realised.

Processing
Tabakoroni open pit ore is currently processed through a toll-treatment arrangement at Syama and forms the basis for processing the underground sulphide ore. The current Syama Oxide Processing plant has a throughput capacity of 1.5Mt per annum of oxide material.
Over the past 12 years, 39 samples from Tabakoroni have been metallurgically tested to determine the ideal processing route. Like Syama, the underground orebody is double refractory in nature. Unlike Syama, Tabakoroni also contains gravity recoverable gold. Consequently, the logical route is a gravity-float-roast-leach. Using test work and Syama plant data, average recovery of 83% has been determined. Further variability float-roast-leach test work is in progress to confirm and optimise this value.
The Syama operation currently consists of two processing trains: a 2.4Mtpa sulphide float-roast-leach circuit and a 1.5Mtpa oxide gravity-leach circuit. As oxide ore may be depleted by 2022, the existing 1.5Mtpa oxide comminution circuit can be utilised to crush and grind Tabakoroni ore. Comminution modelling conducted as part of the Study revealed the comminution circuit capacity to be 1.0Mtpa when processing the harder Tabakoroni sulphide ore. As this exceeds the planned Tabakoroni mining rate, Syama Underground ore could be blended to utilise this capacity.
Five processing options were reviewed as part of the Study; two options to upgrade the current Syama sulphide circuit to handle the combined Syama and Tabakoroni throughput and three options to convert the current oxide plant to process Tabakoroni sulphide ore. The preferred option for the Study, providing a balance between capital expenditure, recovery, circuit stability, operating cost and flexibility to retain capability to process future oxide ore is to convert the oxide plant for sulphide duty including flash flotation and dedicated float cells as shown in Figure 9. The modified flowsheet is shown in Figure 10, with changes highlighted. From here the concentrate will join the current Syama sulphide concentrate recovery circuit for processing sulphide ore.

Capital Cost
The LOM capital costs associated with Study are summarised below in Table 5.
| Cost Category | Capital CostUS$m |
|---|---|
| Underground Mining | 30.3 |
| Treatment | 20.4 |
| Infrastructure (power, paste plant, etc) | 12.6 |
| Pre-production Operating Costs | 23.1 |
| Total Project Capital | 86 |
| Sustaining Capital | 32 |
| Total LOM Capital | 118 |
Table 5: Capital expenditure summary
Project capital expenditure estimates have been prepared by Resolute based on Study estimates provided by Outotec (treatment, paste plant) and similar capital projects completed at Syama. These capital estimates have been consolidated and built into an economic valuation model prepared by Practara for the Study.
A contractor operated model was assumed, based on current contracts in place for both Syama and Tabakoroni, reducing the upfront capital requirement for equipment. The current Tabakoroni open pit infrastructure, Syama camp and medical facilities will be utilised with daily commute to the Tabakoroni mine site. Temporary accommodation and emergency security and medical facilities will be provided at Tabakoroni. Further studies will evaluate the potential benefit of owner purchased equipment scenarios. The commercial production date has been estimated at 14 months after commencement of the decline development. Operating cost incurred prior to this date was capitalised. All capital expenditure incurred post commercial production consist of underground decline and infrastructure development and has been reported as sustaining capital.
Operating Cost
Mining Operating Cost
The mining cost estimate is based on quantities and timelines derived from the mining schedule and fixed and variable rates as per current operating and contract schedules from both Syama and Tabakoroni.
Costing has been based on the following assumptions:
- Contract mining and ore haulage to Syama for LOM
- Owner management and technical services for LOM
- Existing contract rates already in place for items such as explosives, diesel and cement
Costs have been estimated from:
- Contractor mining costs from Resolute's Syama Underground mine development contract
- Ore haulage costs from Tabakoroni open pit haulage contract
- Paste fill cost from Outotec study input and local binder costs
- Resolute input costs from personnel and key consumables such as diesel, electrical power and cement for paste fill
Mining operating costs are those associated with ore development, stoping and ore haulage. It also includes a portion of mining overheads split between capital and operating costs based on tonnes mined.
The total mining operating cost averages US$72.2/t ore mined and is an average between the two mining methods (paste fill stopes and open stopes mined with pillars), and excludes operating costs capitalised prior to commercial production.
Processing Operating Cost
Operating cost for the plant is based on an assumed throughput of 1.0Mtpa and has been determined from the current Syama sulphide and oxide processing plants costs. Total operating costs is estimated at $18.3/t for processing and $11.6/t for General and Administration.
Royalties
Government royalties and refining costs constitute approximately $29m over LOM, derived from the sale of gold.
Rehabilitation and Remediation
Rehabilitation and mine closure estimates have not been fully costed for the Study. Most of the surface rehabilitation has already been incorporated into the current open pit operation. In the economic evaluation model, it has been assumed that the sale of the mine site fixed plant will cover the remaining cost of rehabilitation and remediation work specific to the underground.
Further Exploration opportunities at Tabakoroni and Syama
Ongoing Tabakoroni Exploration
Drilling completed since the last resource estimate was predominantly an infill program which has resulted in an increase of 200,000oz in the updated underground resource detailed above.
The diamond drilling program at Tabakoroni has now moved focus to explore for extensions of the mineralisation down dip and along strike. Results to date from this drilling has confirmed extensions to the mineralisation with several encouraging high-grade gold intersections including bonanza grades of 5m @ 116.3g/t Au in hole TARD773W located deep underneath the Tabakoroni South open pit (refer to Figure 11). Other notable intersections include:
| TADD730 | 9m @ 9.6g/t Au from 185m |
|---|---|
| TADD732 | 4m @ 6.4g/t Au from 188m |
| TADD734 | 4m @ 72.8g/t Au from 209m |
| TADD778 | 17m @ 3.1g/t Au from 250m |
| TADD780 | 7m @ 10.5g/tAu from 405m |
| 7m @ 4.8g/t Au from 356m | |
| TADD781 | 9m @ 5.2g/tAu from 443m |
| TARD773W | 5m @ 116.3g/tAu from 222m |
These drill results prove the down dip extensions of the mineralisation at Tabakoroni is of sufficient grade to support an underground mining operation. Diamond drilling will continue throughout 2020 continuing to expand the mineral resources at Tabakoroni.

Syama Oxide Exploration
Resolute is undertaking an accelerated oxide exploration programs in 2020 to expand oxide resources which is expected to extend the mine life of the Syama oxide circuit.
Results from exploration in the first quarter this year were reported on 16 April 2020 with excellent drill intersections returned from the Syama Northern Pits area and oxide targets adjacent to Tabakoroni. Recent exploration efforts have followed up on the shallow results east of the Tabakoroni pit with continued success.
Tabakoroni Oxide Targets
RC drilling programs undertaken in the first quarter of 2020 identified zones of shallow oxide mineralisation to the east of the Tabakoroni pit and adjacent to the Tabakoroni "Porphyry Splay" pit. These encouraging results have been followed up with programs of infill RC drilling to provide sufficient hole density for resource estimation.
Recent drilling has continued the positive results in the area between the Tabakoroni pit and the "Porphyry Splay" pit (refer to Figure 12). Better results include:
| TARC767 | 8m @ 5g/t Au from 61m |
|---|---|
| TARC772 | 7m @ 6.7g/t Au from 33m |
| TARC788 | 17m @ 1.9g/t Au from 84m |
| TARC791 | 4m @ 52.5g/t Au from 49m |
| TARC795 | 5m @ 6.5g/t Au from 64m |
| TARC799 | 14m @ 2.5g/t Au from 21m |
| TARC803 | 4m @ 7.1g/t Au from 31m |
| TARC805 | 10m @ 4.2g/t Au from 104 |
Mining during 2020 at the "Porphyry Splay" pit extracted over 40,000oz from a small shallow open pit which was in excess of expectations. The mineralisation which was high-grade but discontinuous in resource drilling proved to be more coherent after grade control drilling was completed. This led to the overperformance of the pit in both tonnes and grade.
The overperformance of the open pit mining at the "Porphyry Splay" pit encouraged the exploration team to reevaluate the mineralisation interpretation of the Tabakoroni area and focus on resource remodelling. This work is in progress and the team is confident that the mineralisation footprint will be expanded sufficiently to support a restart to open pit mining activities.
It is expected that the small pit at "Porphyry Splay" will be deepened and expanded laterally to access newly modelled gold mineralisation. The ongoing drilling program continues to expand the mineralisation footprint around the current pits at Tabakoroni.

Syama Oxide Outlook
Gold production from the Syama oxide processing plant is currently sourced from stockpiles of oxide material which will be processed during 2021 and 2022. Open pit operations at Tabakoroni were concluded in May 2020 and will recommence in October 2020 at the Cashew, Tellem and Paysans satellite deposits located 5 to 10km south of the Syama processing infrastructure.
Resources at Cashew are currently approximately 100,000oz at 2g/t gold and at Paysans approximately 270,000oz at 1.7g/t gold (See ASX Announcement dated 17 January 2020).
As of 30 June 2020, oxide stockpiles at Syama are 3.4Mt @ 1.36g/t, containing 150,000oz of gold.
The results in this announcement and the continuing exploration program at Tabakoroni improves confidence in a likely restart of open pit mining operations at the Tabakoroni Porphyry Splay pit and the Gap zone in 2021.
The positive results from the exploration program at Syama North announced in April 2020 are being followed up with drilling programs with the aim of re-establishing open pit mining operations at the Syama northern Satellites.
Significant potential exists for further oxide deposits to be defined within the 85km strike length of Syama greenstones controlled by Resolute
Resolute's exploration programs in Mali are continuing and have been supported by the extensive measures the Company has implemented in response to the COVID-19 pandemic.
Environmental and Social Impact
Société des Mines de Finkolo SA (SOMIFI) operates Tabakoroni located in the Commune of Fourou, Cercle of Kadiolo and Administrative Region of Sikasso. The Tabakoroni open pit operation is a permitted operation (No. 2012- 0057 MEA-SG) with a permitted haul road (No. 2012-0058 MEA-SG) linking it to. Tabakoroni is comprised of four open pits, the Namakan, South, Splay and North pits and these are nearing end of life. The Study considered underground extensions below the current Namakan and North open pits.

Digby Wells was appointed to undertake a study to characterise the biophysical and socio-economic environment of the project area, provide early indication of potential environmental and social risks and impacts and determine the Terms of Reference (ToR) for an Environmental and Social Impact Assessment (ESIA) process that will be required as part of the environmental permitting process. The ESIA will be undertaken in accordance with Malian Law No. 2012-015 of 27 February 2012 (the Mining Code) and the ESIA process will be followed in accordance with Law No. 01-020 / P-RM of 30 May 2011 on Pollution and Nuisance as well as the associated Decrees. The ToR validation site visit request was lodged with the national authorities and the site visit is expected to be completed prior to the end of 2020.
The development and exploitation of the Tabakoroni open pits were the subject of an ESIA and permitting process that concluded in 2012 with receipt of an environmental permit (No. 2012-0057 MEA-SG) for the mining operations and a separate permit for the haul road (No. 2012-0058 MEA-SG). The Study recognises that SOMIFI's operation is already permitted and therefore the ESIA will only cover new activities as part of the underground extension. These activities will, pending future exploration success, remain within the currently permitted fence line of Tabakoroni.
New activities include the mining of the underground sulphide deposits below the Namakan and North open pits. This will require two declines entering from one portal location within the existing Namakan open pit. The underground infrastructure will include return airways, sumps, stockpiles and escapeway access and rises for each decline. An explosives magazine will be located on surface. A paste fill batch plant will need to be constructed to provide cemented paste fill to support tunnel excavations and backfill stopping voids and open pit voids. Waste rock will be disposed underground in mined out stopes, when viable. Excess water and waste rock will be stored in the South, Splay and North open pits – studies and test work are underway to confirm the potential beneficial use of this water. Power capacity will need to be increased and power will be sourced from diesel generators to be relocated from Syama for which a power shed will be erected.
Potential Study Enhancements
Additional Resources
Ongoing exploration success along strike and at depth has not been included into the Study, nor has underground potential below the Splay pit been assessed. On completion of the current drill program the Resource Estimate will be reviewed and will form the basis of future mining studies seeking to expand mining along strike and at depth. The current Study infrastructure is suitable to allow further expansion with minimal further investment.
Disposal of Underground Waste
There is an opportunity to dispose of waste underground, which was not incorporated into the haulage calculations. This has the potential to reduce mining costs and help to reduce the need to paste fill or use of open stopes.
Costs Estimation
The current evaluation model assumes contractor operating models. Further work is required to determine the benefit of owner operated scenarios.
Capital cost estimates were sourced from similar projects at Syama and Tabakoroni or were provided Study budget estimates by suppliers. Further refinement of these estimates could result in further improvements.
Operating cost estimates were sourced from current Syama and Tabakoroni contracts. Negotiation of Study specific operating and supply contracts could further enhance the operating cost estimates. Ongoing paste fill test work could further improve assumptions made in the study.
Mine Plan Optimisation
The repurposed oxide plant has a throughput capacity of 1.0Mtpa. The Study provides only 650ktpa to 750ktpa, which provides mining upside opportunity for Tabakoroni either through rescheduling, or through further exploration success.

Due to the relatively low mining production rate, there is ample spare capacity in the current equipment numbers, which could either be filled through further design or scheduling optimisation, or through additional exploration success providing additional mining areas.
Ground conditions continue to improve at depth, providing opportunity to increase both stope lengths and level spacing. Increased stope lengths increased production throughput and reduce slot rising and paste wall requirements. Increased level spacings reduce development requirements and can increase stope productivity. The basis of estimate for the study assumed a conservative 20m for both level spacing and maximum stoping length.
Process Enhancement
The spare capacity in the process plant could either be filled with additional Tabakoroni ore or by supplementing with Syama underground or open pit sulphide ore. These options have not been included in the Study.
Ongoing variability and process optimisation test could further enhance the process recovery estimate of 83% used in the Study. Test work have shown recoveries of up to 87%, with a large gravity recovery component.
Timeline and Investment Decision
Work is continuing to extend the Tabakoroni Underground Mineral Resources. This work is expected to allow for further refinements to the proposed mine plan and the delineation of an enlarged Ore Reserve for the Tabakoroni Underground. The results of this work will be published when available and will inform a future investment decision. The timing of any development of a Tabakoroni underground operation will be matched to the expected mine life of the existing Syama oxide operation and will be outlined in the Syama Life-of-Mine update to be completed and published during the current quarter.

| Geology | •Deposit type, geological setting and style of mineralisation. | The Syama Project is found on the northern margin of the Achaean-Proterozoic Leo Shield which forms thesouthern half of the West African Craton. The project area straddles the boundary between the Kadiana–Madinani terrane and the Kadiolo terrane. The Kadiana-Madinani terrane is dominated by greywackes and anarrow belt of interbedded basalt and argillite. The Kadiolo terrane comprises polymictic conglomerate andsandstone that were sourced from the Kadiana-Madinani terrane and deposited in a late-to syntectonic basin. |

| Prospects are centred on the NNE striking, west dipping, Syama-Bananso Fault Zone and Birimian volcanosedimentary units of the Syama Formation. The major commodity being sought is gold. | ||
|---|---|---|
| The Tabakoroni deposit is hosted in upright tightly folded greenstone rocks of the Syama Formation, comprisinginterbedded basalt and sediment units, and an overlying complex sequence of deep marine and turbiditicsediments. The sequence overlying the basalts contains interbedded carbonaceous units (silts and shales) thatare preferentially deformed, and which form the Tabakoroni Main Shear Zone (TMSZ) that lies along theapproximate contact of the greenstone-sediment sequence. Gold mineralisation occurs within the TMSZassociated with quartz vein stockworks and stylolitic quartz reefs. | ||

| The Environmental & Social Impact Study –"Société des Mines de Syama, Syama Gold Mine, Mali", dated 2007indicated there was minimal potential for acid mine drainage from waste rock due to the elevated carbonatecontent which buffers a potential acid generation. Resolute maintains a plan for progressive rehabilitation ofwaste rock landforms as part of ongoing mine development and waste rock dumping. | ||||
| The landform of tailings impoundments does not have a net acid generating potential. The largest volume isflotation tailings where the sulphide minerals have already been removed from the host rock. Its mineralogyincludes carbonates which further buffer any acid-formation potential from sulphides that may also be present. | ||||
| Cyanide levels in the leached-calcine tailings are typically less than 50 ppm in the weak acid dissociable form.Groundwater away from the tailings landform is intercepted by trenches and sump pumps. | ||||
| Sulphur dioxide is generated from the roasting of gold concentrate so that gold can be extracted and refined.Tall-Stack "dispersion" of the sulphur dioxide emission is monitored continuously. Prevailing weather anddissipation of the sulphur dioxide is modelled daily to predict the need to pause the roasting process to meet theair quality criteria set out in the Environmental & Social Impact Study. | ||||
| • | Whether assumed or determined. If assumed, the basis for theassumptions. If determined, the method used, whetherwet or dry,the frequency of the measurements, the nature, size andrepresentativeness of the samples. | Site personnel have completed numerous bulk density comparative estimates on HQ drill coreto assessvariability using the Archimedes method of dry weight versus weight in water. This method was used for 71% ofthe bulk density measurements. The other 29% is by unknown method. | ||
| Bulk density | • | The bulk density for bulk material must have been measured bymethods that adequately account for void spaces (vugs, porosity,etc), moisture and differences between rock and alteration zones | On the basis of the data collected the following SG estimates wereapplied to the model by weathering type: | |

| Classification | ••• | The basis for the classification of the Mineral Resources intovarying confidence categories.Whether appropriate account has been taken of all relevantfactors (i.e. relative confidence in tonnage/grade estimations,reliability of input data, confidence in continuity of geology andmetal values, quality, quantity and distribution of the data).Whether the result appropriately reflects theCompetent Person'sview of the deposit. | The Measured Mineral Resource classification is based on good confidence in the geology and gold gradecontinuity with 12.5 m x 12.5 m spaced drillhole density inthe central part of the deposit.The Indicated Mineral Resource classification is based on good confidence in the geology and gold gradecontinuity with less than 50 m x 50 m spaced drillhole density in the central part of the deposit.The Inferred Mineral Resource classification is applied to extensions of mineralised zones on the margins of thedeposit where drill spacing is more than 50 m x 50 m and the extents of mineralisation at depth.The validation of the block model has confirmed satisfactory correlation of the input data to the estimated gradesand reproduction of data trends.The Mineral Resource estimate appropriately reflects the view of the Competent Persons. |
|---|---|---|---|
| Audits orreviews | • | The results of any audits or reviews of MineralResourceestimates. | The Mineral Resource has been audited internally and in conjunction with resource consultants at Optiro Pty Ltdas part of the routine validation process. There has been no external review of the Mineral Resource estimate. |
| Discussion ofrelativeaccuracy/confidence | ••• | Where appropriate a statement of the relative accuracy andconfidence level in the Mineral Resource estimate using anapproach or procedure deemed appropriate by the CompetentPerson. For example, the application of statistical or geostatisticalprocedures to quantify the relative accuracy of the resource withinstated confidence limits, or, if such an approach is not deemedappropriate, a qualitative discussion of the factors that could affectthe relative accuracy and confidence of the estimate.The statement should specify whether it relates to global or localestimates, and, if local, state the relevant tonnages, which shouldbe relevant to technical and economic evaluation. Documentationshould include assumptions made and the procedures used.These statements of relative accuracy and confidence of theestimate should be compared with production data, whereavailable. | The relative accuracy of the Mineral Resource estimate is reflected in the reporting of Measured, IndicatedandInferred resource categories as defined by 2012 JORC Code guidelines.The estimate is considered to be relevant to an annual level of reporting of tonnage and grade.The estimation was compared with the production history at Tabakoroni and it is within 15% which is within thelimits for the relevant classifications. |
