Increases in Mineral Resources and Ore Reserves from Ex loration Success p

Highlights

• Mineral Resources increased by 1.7 million ounces (Moz) to 11.2 Moz of gold, net of depletion

• Ore Reserves have increased by 0.6 Moz to 4.6 Moz, net of depletion

• Syama Mineral Resources increased significantly following exploration success at Syama North

• Mineral Resources at Syama North increased to 3.2 Moz and Ore Reserves increased to 854 koz, with 10% (85koz) of oxide material

• Further 126 koz of Mineral Resources at Syama Underground converted to Ore Reserves due to improved mining productivities

• Mako Ore Reserves and Mineral Resources reduced in line with mining depletion

Resolute Mining Limited (ASX/LSE: RSG, Resolute or the Company) is pleased to announce the Company’s Annual Ore Reserve and Mineral Resource Statement at 31 December 2022.

Ore Reserves have increased to 4.6 Moz of gold and Mineral Resources have increased to 11.2 Moz of gold after accounting for the effects of mining depletion, improved productivities underground and exploration success.

A detailed breakdown of the Company’s Ore Reserves and Mineral Resources at 31 December 2022 representing the Syama and Mako operations is presented in the tables below. The 2022 Annual Ore Reserve Statement is included at Table 3 of this announcement and the 2022 Annual Mineral Resource Statement is included at Table 4.

At 31 December 2022 Resolute’s direct share of Ore Reserves was 3.8 Moz and Mineral Resources of 9.1 Moz.

The exploration success at Syama North has added 2 million ounces of gold to the Mineral Resource this year and added 850,000oz to the Ore Reserve

All tonnes and grade information have been rounded to reflect the relative uncertainty of the estimate, small differences may be present in the totals.

Resolute’s Chief Executive Officer, Mr Terry Holohan, commented:

“The continued success of the drilling program at Syama North over the second half of 2022 exceeded our expectations. The drill rigs are still turning on this contiguous strike discovery of over 6km which remains open at depth. At this stage the 850 koz of Syama North Ore Reserves focus only on the widest sections of the A21 pit, thus we expect further updates later this year as in-fill drilling continues delineating additional economic mineralisation. It is also worth noting that the 10% oxides delineated at Syama North now represent some of the highest grades of oxides at Syama such that they will get processing preference once mining starts in earnest.

“I am extremely proud of the 31 December 2022 Mineral Resource and Ore Reserve Statement, which incorporates these significant additions to our business, demonstrating our exploration team's achievements.

Also due to recent sustainable efficiency improvements at the Syama underground operation over 2022, the Company was able to convert a further 126 koz of the existing Mineral Resource Estimate to Ore Reserves.

“The company now turns its focus to the Syama North pre-feasibility study (PFS), which is intended to be the first step in exploiting the sulphide reserve, due for publication in the middle of 2023. Significant additions to our Mineral Resources and Ore Reserves, such as Syama North clearly demonstrate that the Syama Belt is surprisingly under-explored and justifies the need for further exploration work to be undertaken along the prospective >85 km of strike.”

Ore Reserves as at 31 December 2022 on a 100% basis total 4.6 Moz after mining depletion with the increase coming from the new reserve at Syama North.

In Mali, the Ore Reserves at the Syama Gold Mine (Syama) increased due to an expansion in the Ore Reserves at Syama North. Overall 40% of the Measured and Indicated Mineral Resources were converted into Ore Reserves. We expect the Ore Reserve to increase this year as we continue to convert Inferred Resources to the Indicated category. Exploration success at Syama North in 2022 led to a significant increase in Mineral Resources after completing intensive drilling programs throughout the year. The large increase in Measured and Indicated Mineral Resources led to a substantial increase in Ore Reserves at Syama North to 10.6 million tonnes (Mt) at 2.5g/t Au for 854,000oz. Drilling is continuing at Syama North with the expectation of significant increases in the Ore Reserves during the year.

Underground Ore Reserves at Syama only decreased slightly as inventory increases in the cave flow modelling, due to productivity improvements offset mining depletion reductions.

Ore Reserves at the Mako Gold Mine (Mako) decreased in line with mining depletion.

Resolute’s asset ownership is 80% of Syama (Mali Government 20%), 90% of Tabakoroni (Mali Government 10%), 90% of Mako (Senegalese Government 10%). As such, the Company’s fully attributable Ore Reserves position net government interests, is 3.8 Moz of gold.

Mineral Resources (inclusive of Ore Reserves) at 31 December 2022, on a 100% basis, contain 11.2 Moz of gold. The Company’s fully attributable Mineral Resources position, net of government interests is 9.1 Moz of gold.

In Senegal, the Mineral Resources at Mako decreased in line with mining depletion. At Syama the Mineral Resources increased significantly in 2022 following the addition of 2 Moz discovered at Syama North during the year.

The highly successful drilling programs in 2021 and 2022 at Syama North have outlined a company significant Mineral Resource which has the potential to transform the mining operation at Syama. During 2022 the Syama North Mineral Resource increased to 34Mt @ 2.9g/t Au for 3.2 Moz an increase of 2 Moz.

Summary of Mineral Resource Parameters

A summary of JORC Table 1 is provided below for compliance regarding the Mineral Resources reported within and in-line with the requirements of ASX Listing Rule 5.8.1. There has been a material change to Syama Satellite Mineral resource as detailed in the ASX release dated January 2023. Syama Mineral Resources increased significantly following exploration success at Syama North.

Geology and geological interpretation

The Syama Project is found on the northern margin of the Achaean-Proterozoic Leo Shield which forms the southern 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 a narrow belt of interbedded basalt and argillite. The Kadiolo terrane comprises polymictic conglomerate and sandstone 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.

Sampling and sub-sampling techniques

Diamond core has been sampled at 1m intervals and cut in half to obtain a 2-4kg sample.

Reverse circulation samples were collected on 1m intervals by riffle split (dry) or by scoop (wet) to obtain a 2-4kg sample (Syama) or 1-3kg sample.

Sample preparation for diamond core and RC samples includes oven drying, crushing to 10mm and splitting, pulverising to 85% passing -75um. These preparation techniques are deemed to be appropriate to the material and element being sampled.

Drill core coarse duplicates were split by the laboratory after crushing at a rate of 1:20 samples. Reverse circulation field duplicates were collected by the company at a rate of 1:20 samples.

Drilling techniques

Drill types used include diamond core of HQ and NQ sizes. Core is oriented at 3m down hole intervals using a Reflex Act II RD Orientation Tool and more recently using a Reflex north seeking gyro instrument.

Classification criteria

Mineral Resources were classified in accordance with the Australasian Code for the Reporting of Exploration Results, Mineral Resources and Ore Reserves (JORC, 2012).

The deposit has been classified as Measured, Indicated, and Inferred Mineral Resource based on a combination of quantitative and qualitative criteria which include geologic continuity, confidence in volume models, data quality, sample spacing, lode continuity, and estimation parameters (number of informing composites, estimation pass number, kriging quality parameters, and minimum and average distance composites).

The Measured portion of the Resource was defined using areas populated on the first estimation pass, within 20m of informing composites; the kriging efficiency and slope of regression were generally >=0.7; and high confidence exists in lode continuity (strike and thickness).

The Indicated portion of the Resource was defined using areas populated on the first two estimation passes within 50m of informing composites; the kriging efficiency and slope of regression were generally >=0.7; and moderate to high confidence exists in lode continuity (strike and thickness).

Mineralisation that not classified by the above parameters has been classified as Inferred.

The input data is comprehensive in its coverage and does not favour or misrepresent the in situ mineralisation. The definition of the mineralised zones is based on a high level of geologic understanding from good quality

sample data, producing models of continuous mineralised lodes. Validation of the block model shows good correlation of the input data to the block estimated grades.

The Mineral Resource estimate appropriately reflects the view of the Competent Person

Sample analysis method

All samples were dispatched to ALS Bamako for gold analysis by 30g fire assay fusion with AAS instrument finish (method code Au-AA25). Over-range results were re-analysed and reported by 30g fire assay fusion with gravimetric finish (method code Au-GRA21). The analytical method was appropriate for the style of mineralisation.

No geophysical tools were used to determine elemental concentrations.

Quality control (QC) procedures included the use of certified standards (1:40), non-certified sand blanks (1:40), diamond core coarse duplicates (1:20) and reverse circulation field duplicates (1:20).

Laboratory quality control data, including laboratory standards, blanks, duplicates, repeats, grind size results and sample weights were also captured into the digital database.

Analysis of the QC sample assay results indicates that an acceptable level of accuracy and precision has been achieved.

Estimation methodology

Estimation of gold grade has been completed using Ordinary Kriging (OK).

The deposit mineralisation has been constrained by wireframes constructed using a combination of downhole gold assay and associated lithological logging. These lode wireframes have been used to define domain codes used for estimation. The drillholes have been flagged with the domain code and composited using the domain code to segregate the data.

Domain boundary analysis has been undertaken, with hard boundaries used for all domains.

Drillholes have been composited to 1m intervals using Leapfrog Geo 2021.2.5 with residual lengths distributed evenly across all composites. There are no residual samples.

The influence of extreme gold assays has been reduced by top-cutting across selected domains. Top-cuts have been determined using a combination of log probability, log histogram, and mean-variance plots. Topcuts have been reviewed and applied to the composites on a domain-by-domain basis.

Variography has been determined using Datamine Supervisor v.8.14 software using top-cut values. Where there is insufficient data in individual domains to generate meaningful variograms, domains have been grouped, or variograms borrowed from other similar domains.

Drillhole data spacing ranges from 10m spacing in areas of dense drilling to approximately 100m spacing in sparsely drilled, deeper areas.

The block model parent block size is 5m (X) by 10m (Y) by 5m (Z) with sub-blocks down to 0.3125m (X) by 0.625m (Y) by 0.3125m (Z), with the sub-blocks estimated at the scale of the parent block. The block size is considered appropriate for the drillhole spacing throughout the deposit.

Grade estimation has been completed in three passes:

Pass 1 estimation has been undertaken using a minimum and maximum number of sample composites (determined using Datamine Supervisor v.8.14 KNA tool) into a search ellipsoid with dimensions equal to half the variogram range of the domain.

Pass 2 estimation has been undertaken with the same minimum/maximum samples as Pass 1 into a search ellipsoid twice the first pass.

Pass 3 estimation has been undertaken with a minimum of 4 samples, and the same maximum number of samples as the first two passes into a search ellipsoid twice the second pass

ASX/LSE:RSG I rml.com.au

Page 8 of 108

At 31 December 2022

==> picture [16 x 12] intentionally omitted <==

A four drillhole limit has been applied to the passes.

Previous Mineral Resource estimates are comparable in size and scope when considering the additional extensional drilling included in the current estimate.

The Mineral Resource estimate has been validated using visual validation tools, mean grade comparisons between the block model and declustered composite grade means, and swath plots comparing the input composite grades and the block model grades by Northing, Easting, and RL

No selective mining units are assumed in the estimate. There will be no by-products recovered from mining. No additional or deleterious elements have been estimated. The model focuses on interpreting mineralisation beneath existing open pits. Historical reconciliation data is incomplete and has not been used.

Basis for selected cut-off grade

A cut-off grade of 1.0 g/t Au has been used for construction of mineralised wireframes, based on mining parameters of the nearby Syama and Tabakoroni deposits.

Mining and metallurgical methods and other material modifying factors

Extensive metallurgical investigations and reporting have been completed prior to the commencement of mining and milling at the nearby Syama deposit.

The processing method involves crushing, milling, flotation and roasting, followed by conventional CIL recovery.

There is no evidence to suggest that the metallurgical characteristics of ore extracted from Syama North would change from that encountered at Syama.

Summary of Ore Reserve Parameters

A summary of JORC Table 1 is provided below in Appendix for compliance regarding the Ore Reserves reported within and in-line with the requirements of ASX Listing Rule 5.9.1. There has been a material change to the Syama North Satellite Reserve; i.e, change in tonnes, grades, rock type (Oxide; Transistional and Fresh).

Material assumptions and the outcomes of the [preliminary] feasibility study

The Syama North deposit consist of A21, Beta, Alpha & Ba04 pits.

Feasibility Studies were completed for mining of Northern satellite deposits in 2009, and mining of satellite pits has been occurring since then. Recent drilling in Syama North has identified a significant resource in sulphide, spread across the Syama North region, an extension to the known oxide deposit. Additional drilling was completed targeting the A21 area and the resource model was updated in Dec 22 with additional information. Overall, 40% of the Measured and Indicated Mineral Resources were converted into Ore Reserves. Infill drilling is ongoing, and we expect the Ore Reserve to increase this year as we convert Inferred Resources to Indicated category.

Pit was reoptimized using the new resource model and redesigned to match the latest optimisation. All Reserves were declared as Probable as more test works and drilling is ongoing to firm up the modifying factors (geotechnical inputs).

ASX/LSE:RSG I rml.com.au

Page 9 of 108

At 31 December 2022

The work undertaken to date has addressed all material Modifying Factors required for the conversion of a Mineral Resources estimate into an Ore Reserve estimate and has shown material change where there is a significant increase in Measured and Indicated Mineral Resources. As a result, Ore Reserves at Syama North increases to 10.6 million tonnes (Mt) at 2.5g/t Au for 854,000oz. Drilling is continuing at Syama North with the expectation of significant increases in the Ore Reserves during the year.

Classification criteria

The Ore Reserves are based on the Mineral Resource estimate detailed in the ASX release dated January 2023.

Proved and Probable Ore Reserves were declared based on the Measured and Indicated Mineral Resources. None of the Measured Mineral Resource was converted to Proven Ore Reserves as the PFS study for plant expansion is underway and drilling is ongoing to firm up the geotechnical inputs.

Mining methodology

Mining is planned to be undertaken by conventional open pit methods of drill and blast, followed by load and haul. The Ore from Syama North will be trucked to Syama and treated through Syama Processing plant.

Detailed pit design work was completed based on pit optimisations result. Only Measured and Indicated Resources were used in the pit optimisation.

Processing method

Metallurgical test work was conducted on multiple samples. The tests indicated that, similarly to the Syama ore. The processing of the ore will be similar to that of the Syama sulphide circuit which has been in operation for several years and is well understood, consisting of the following stages:

• Crushing and grinding utilising the existing oxide process plant infrastructure

• Gravity gold recovery utilising the existing oxide gravity circuit

• Flotation to produce a sulphide rich concentrate

• Concentrate thickening

• Roasting, followed by calcine quench and wash

• Carbon-in-leach (CIL)

• Tailings disposal

A total gold recovery of 86%, 80% and 78%, has been assumed for Oxide, Transistional and Fresh Material respectively, based on test results to date. This is in line with similar ore being processed at Syama.

Basis for selected cut-off grade

The mill cut-off grade is used for Reserve Reporting. It is the derived from the long-term gold price, processing cost, mining dilution, royalty and selling costs. The above-mentioned economic parameters are the same as in the Financial Model 2022

Estimation methodology

The reported Ore Reserve estimates for Syama North are based on pit optimisations conducted using the Lerchs-Grossman (LG) algorithm utilizing the NPV Scheduler and reviewed in Whittle to calculate the optimal pit at specific input parameters and pit designs. Costs are based on existing contract mining and haulage rates and site costs which are understood with a high degree of accuracy.

Detailed pit design work was completed based on pit optimisations result. Only Measured and Indicated Resources were used in the pit optimisation.

Overall slope angles are dependent on rock type; approximately 34° for Oxide, 38° for Transisitional and 50° for Fresh as recommended by Geotechnical consultants and operational experience in mining other similar pits in same region.

A 5% dilution and 10 % mining loss factor applied. All Inferred material is treated as waste and is excluded from Reserve Reporting.

Inferred Mineral Resources are not included in the pit optimisation and pit design. A mining and production schedule were completed with Inferred Mineral Resource treated as waste. As a result, the conversion of Inferred Mineral Resource to processed product is not required for the overall financial viability of the project.

Material modifying factors

Detailed pit design work was completed based on pit optimisations result. Only Measured and Indicated Resources were used in the pit optimisation.

Overall slope angles are dependent on rock type; approximately 34° for Oxide, 38° for Transistional and 50° for Fresh as recommended by Geotechnical consultants and operational experience in mining other similar pits in same region.

A 5% dilution and 10 % mining loss factor applied. The Dilution and mining loss assumptions are derived from the reconciliation results at Syama. All Inferred material is treated as waste and is excluded from Reserve Reporting.

The Syama North pits are located within approximately 8km of Syama. Ore is trucked to Syama where it is processed at Syama. General and administration costs are shared between the oxide plant and the sulphide plant. As part of ongoing operations, capital and operating budgets are prepared from first principles and considering existing contractual agreements.

The processing plant produces gold doré (without problematic deleterious elements) that is subsequently refined offsite. Refining costs are not material.

A gold price of US$1,500/oz formed the basis of the Ore Reserves

Exchange rates used for planning purposes are from consensus forecasts provided by external corporate advisers.

Ad valorem Government royalties of 6% are payable on gold production.

No penalties are incurred, nor is any revenue received from co-products.

CRITERIA JORC CODE EXPLANATION	COMMENTARY Diamond core has been sampled at 1m intervals and cut in half to obtain a 2-4kg sample. Reverse circulation samples were collected on 1m intervals by riffle split (dry) or by scoop (wet) to obtain a 2-4kg sample. Sample preparation for diamond core and RC samples includes oven drying, crushing to 10mm and splitting, pulverising to 85% passing -75um. These preparation techniques are deemed to be appropriate to the material and element being sampled. Drill core coarse duplicates were split by the laboratory after crushing at a rate of 1:20 samples. Reverse circulation field duplicates were collected by the company at a rate of 1:20 samples. Resolute sampling, sample preparation and quality control protocols are of industry standard and all attempts were made to ensure an unbiased representative sample was collected. The methods applied in this process were deemed appropriate by the Competent Person. Sub-sampling techniques and sample preparation completed by previous owners is not known. All Resolute samples were analysed for gold by 30g fire assay fusion with AAS instrument finish. The analysis was performed by ALS Bamako or SGS Morila. The analytical method was appropriate for the style of mineralisation. No geophysical tools were used to determine elemental concentrations. Quality control (QC) procedures included the use of certified standards and blanks (1:20), non- certified sand blanks (1:20), diamond core coarse duplicates (1:20) and reverse circulation field duplicates (1:20). Laboratory quality control data, including laboratory standards, blanks, duplicates, repeats and grind size results were also captured into the digital database. Analysis of the QC sample assay results indicates that an acceptable level of accuracy and precision has been achieved. The assay techniques used by Randgold and BHP include fire assay fusion with AAS instrument finish and aqua regia with AAS. The majority of the samples were analysed at the onsite Syama laboratory. Due to the historical nature of the Randgold and BHP data the assay procedures are not known for all samples.
Sub-sampling techniques and sample preparation • If core, whether cut or sawn and whether quarter, half or all core taken. • If non-core, whether riffled, tube sampled, rotary split, etc. and whether sampled wet or dry. • For all sample types, the nature, quality and appropriateness of the sample preparation technique. • Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. • 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. • Whether sample sizes are appropriate to the grain size of the material being sampled.
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. • For geophysical tools, spectrometers, handheld XRF instruments, etc., the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. • 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.
Verification of sampling and assaying • The verification of significant intersections by either independent or alternative company personnel. • The use of twinned holes. • Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. • Discuss any adjustment to assay data.	Verification of significant intersections have been completed by company personnel and the competent person. No drill holes within the resource area were twinned. Drill holes were logged onto paper templates or Excel templates with lookup codes, validated and then compiled into a relational SQL 2012 database using DataShed data management software. The database has a variety of verification protocols which are used to validate the data entry. The drill hole database is backed up daily to the head office server. Assay result files were reported by the laboratory in PDF and CSV format and imported directly into the SQL database without adjustment or modification. Resolute has conducted extensive reviews, data validation and data verification on the historic data collected by the previous owners, Randgold and BHP.

Mineral tenement and land tenure status	• Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. • The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area. Drilling was conducted within the Malian Exploitation Concession Permit PE 93/003 which has an area of 200.6km2. Resolute Mining Limited has an 80% interest in the Syama project and the Exploitation Permit PE—93/003, on which it is based, through its Malian subsidiary, Sociêtê des Mines de Syama SA (SOMISY). The Malian Government holds a free carried 20% interest in SOMISY. The Permit is held in good standing. Malian mining law provides that all mineral resources are administered by DNGM (Direction Nationale de la Géologie et des Mines) or National Directorate of Geology and Mines under the Ministry of Mines, Energy and Hydrology.
Exploration done by other parties	• Acknowledgment and appraisal of exploration by other parties. The Syama deposit was originally discovered by a regional geochemical survey undertaken by the Direction National de Géologie et des Mines (DNGM) with assistance from the United Nations Development Program (UNDP) in 1985. There had also been a long history of artisanal activities on the hill where an outcropping chert horizon originally marked the present-day position of the open pit. BHP during 1987-1996 sampled pits, trenches, auger, RC and diamond drill holes across Syama prospects. Randgold Resources Ltd during 1996-2000 sampled pits, trenches, auger, RAB, RC and diamond drill holes across Syama prospects.
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 the southern 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 a narrow belt of interbedded basalt and argillite. The Kadiolo terrane comprises polymictic conglomerate and sandstone 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 volcano- sedimentary units of the Syama Formation. The major commodity being sought is gold.
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: o easting and northing of the drill hole collar. o elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar. o dip and azimuth of the hole. o down hole length and interception depth. o Whole 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. No new exploration results have been reported in this release. The listing of the entire drill hole database used to estimate the resource was not considered relevant for this release.

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. • 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. • The assumptions used for any reporting of metal equivalent values should be clearly stated. No new exploration results have been reported in this release. Metal equivalent values are not used in reporting.
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’). The mineralisation is steeply dipping at approximately 600 from the horizontal. Most of the drill holes are planned at local grid 0900at a general inclination of -600east to achieve as close to perpendicular to the ore zone as possible. At the angle of the drill holes and the dip of the ore zones, the reported intercepts will be slightly more than true width.
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. Relevant maps, diagrams and tabulations are included in the body of text.
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. Mineral Resources are being reported in this announcement. No new exploration results have been reported in this release.
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. No geophysical and geochemical data and any additional exploration information has been reported in this release, as they are not deemed relevant to the release.
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. Depth extension drilling is planned to test the down-dip potential of the Syama ore body at depth, and beneath the current limit of drilling.

Estimation was completed in Datamine Studio RM using Categorical Indicator (CI) approach to define the mineralised blocks followed by an Ordinary Kriged (OK) model to estimate the gold grade. Grades were estimated into parent block of 5mE by 12.5mN by 5mRL for Syama underground and 10mE by 25 mN by 10mRl for Syama South and Nafolo. Sub- celling down to 5mE by 12.5mN by 5mRL was employed for resolution of the mineralisation boundary at Nafolo.

The categorical model used a cut-off of 1 g/t gold once the mineralised blocks have been identified another categorical model within this mineralisation is carried out at a cut-off of 2 g/t to identify higher grade zones. A 5mE by 12.5mN by 5mRL block size was employed during the categorical process used to delineate mineralised regions.

After this process, the model was reblocked up to 5mE by 25mN by 10mRL for Nafolo while retaining the smaller size blocks as subcells at mineralisation boundaries.

The resource model included estimates for sulphide sulphur and organic carbon which assist with metallurgical characterisation. The sulphide sulphur is estimated via a categorical indicator approach with a cut-off grade of 1% to identify the higher grade blocks and then an OK estimation was carried out within these blocks. Organic carbon was just estimated without boundaries into the block model. There are reduced assays at depth of these two elements so there is some smoothing at depth.

Kriging neighbourhood analysis was performed to optimise the block size, sample numbers and discretisation levels with the goal of minimising conditional bias in the gold grade estimates.

A larger blocks size for Nafolo and Syama South was chosen based on this analysis than was employed in the previous resource estimate and the wider drill spacing.

A total of three search passes was used, with the first search pass set to the range of the variogram for each element. A minimum of 10 and a maximum of 30 samples were used. The search stayed the same for the second pass but was increased by a factor of 2 for the third and final pass. The minimum number of samples was reduced to 8 for the second pass and 6 for the third pass.

Semi-soft boundaries were used between the higher grade and lower grade domains and between the lower grade domain and the waste domain for Syama Main. Two samples either side of the mineralisation boundary were used in the OK estimation. Hard boundaries were utilised for the domains at Nafolo, Syama South and all of the domains for sulphide sulphur.

Un-estimated blocks (less than 1% for gold) were assigned the domain average grades. No deleterious elements were found in the ore.

No selective mining units have been assumed.

No assumptions have been made regarding the correlation of variables although it is noted that a broad positive correlation exists between gold and sulphur.

Estimation searches have been orientated to respect the orientation of the Syama Formation which hosts the mineralisation.

Top cuts were applied to reduce the variability of the data and to remove the outliers.

The estimated block model grades were visually validated against the input drillhole data and comparisons were carried out against the drillhole data and by northing and elevation slices. Global comparison between the input data and the block grades for each variable is considered acceptable (±10%).

It is always necessary as part of or assumptions 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 a green fields project, may not always be well advanced, the status of early consideration of these potential environmental impacts should be reported. Where these aspects have not been considered this should be reported with an explanation of the environmental assumptions made.

It is a requirement of Decree No.03-594/P-RM of 31 December 2003 of Malian law that an Environmental and Social Impact Study (Étude d’Impact Environmental et Social – EIES) must be undertaken to update the potential environmental and social impacts of the mine’s redevelopment. The EIES for the Syama Gold Mine was approved in November 2007 and an Environment Permit (07- 0054/MEA – SG) was issued by the Ministry of Environment and Sanitation on the 22 November 2007. The Ministry of Environment conduct timely reviews of the Syama Gold Mine to ensure that the Company maintains compliance with the EIES guidelines.

At Syama there are three key practices for disposal of wastes and residues namely, stacking of waste rock from open pit mining; storage of tailings from mineral processes; and “tallstack dispersion” of sulphur dioxide from the roasting of gold bearing concentrate. All waste disposal practices are in accordance with the guidelines in the EIES.

The Environmental and Social Impact Study – “Société des Mines de Syama, Syama Gold Mine, Mali, dated 2007 indicated there was minimal potential for acid mine drainage from waste rock due to the elevated carbonate content which buffers a potential acid generation. Resolute maintains a plan for progressive rehabilitation of waste 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 is flotation tailings where the sulphide minerals have already been removed from the host rock. Its mineralogy includes 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 tailing’s 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 and dissipation of the sulphur dioxide is modelled daily to predict the need to pause the roasting process to meet the air quality criteria set out in the Environmental and Social Impact Study.

COMMENTARY

Site personnel have completed numerous bulk density comparative estimates on HQ drill core to assess variability using the Archimedes method of dry weight versus weight in water. This method was used for 96% of the bulk density measurements.

Other tests were completed by SGS using the pycnometer method.

Based on the data collected the following SG estimates were applied to the model:

• Syama Formation 2.82

Classification

• The basis for the classification of the Mineral Resources into varying confidence categories.

• Whether appropriate account has been taken of all relevant factors (i.e. 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.

The Measured Mineral Resource classification is based on good confidence in the geology and gold grade continuity with less than 25m x 25m spaced drillhole density in the central part of the deposit directly below the current pit.

The Indicated Mineral Resource classification is based on good confidence in the geology and gold grade continuity with less than 75m x 75m 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 the deposit where drill spacing is more than 100m x 100m and the extents of mineralisation at depth. The Nafolo orebody to the south of Syama which is tested by wider drill spacing has also been classified as Inferred.

The validation of the block model has confirmed satisfactory correlation of the input data to the estimated grades and reproduction of data trends.

The Mineral Resource estimate appropriately reflects the view of the Competent Persons.

The outcomes of this work are part of a continuous improvement program that contributes to the waste rock dump management plans, annual reporting and consultation-committee meetings with government and community representatives.

Tailings storage for the life of mine is forecast to be impounded over the existing footprint area approved in the Environmental & Social Impact Study. Progressive raising of the tailings impoundments will occur to contain life-of-mine storage capacity. Routine progress on the monitoring is reported to government and at stakeholder meetings in concert with routine inspections by government representatives.

The Syama Project is mature in its operating life with environmental management permitted by an Environmental Authority and supported by an Environmental Management Plan. No impediments are anticipated to the development of the underground mine

Tabakoroni drilling was completed within the Finkolo-Tabakoroni Exploitation Licence PE 13/19. Resolute Mining Limited has an 90% interest in Exploitation Permit PE 13/19, through its Malian subsidiary, Sociêtê des Mines de Finkolo SA (SOMIFI). The Malian Government holds a free carried 10% interest in SOMIFI. The Permits are held in good standing. Malian mining law provides that all Mineral Resources are administered by DNGM (Direction Nationale de la Géologie et des Mines) or National Directorate of Geology and Mines under the Ministry of Mines, Energy and Hydrology.
Exploration done by other parties	•Acknowledgment and appraisal of exploration by other parties. Etruscan Resources Inc explored Tabakoroni during 2002-2003 by auger, aircore, RC and diamond drill hole tails. The Tabakoroni area was previously explored by BHP (1988-1990) and Barrick Gold (1990) by auger, pits, trenches, RAB and diamond core drilling.
Geology	•Deposit type, geological setting and style of mineralisation. The Tabakoroni deposit is hosted in upright tightly folded greenstone rocks of the Syama Formation, comprising interbedded basalt and sediment units, and an overlying complex sequence of deep marine and turbiditic sediments. The sequence overlying the basalts contains interbedded carbonaceous units (silts and shales) that are preferentially deformed, and which form the Tabakoroni Main Shear Zone (TMSZ) that lies along the approximate contact of the greenstone-sediment sequence. Gold mineralisation occurs within the TMSZ associated with quartz vein stockworks and stylolitic quartz reefs.
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: o easting and northing of the drill hole collar o elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar o dip and azimuth of the hole o down hole length and interception depth o Whole 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. All information, including easting, northing, elevation, dip, azimuth, coordinate system, drill hole length, intercept length and depth are measured and recorded in UTM Zone 29 WGS84. The Syama belt is mostly located on the Tengrela 1/200,000 topo sheet (Sheet NC 29-XVIII). The Tabakoroni local grid has been tied to the UTM Zone 29 WGS84 co-ordinate system. Spectrum Survey and Mapping from Australia established survey control at Tabakoroni using AusPos online processing to obtain an accurate UTM Zone 29 (WGS84) and ‘above geoid’ RL for the origin of the survey control points. Accuracy of the survey measurements is considered to meet acceptable industry standards. Drill hole information has been tabulated for this release in the intercepts table of the accompanying text. For completeness the following information about the drill holes is provided: • Easting, Northing and RL of the drill hole collars are measured and recorded in UTM Zone 29 (WGS84). • Dip is the inclination of the drill hole from horizontal. A drill hole drilled at -60° is 60° from the horizontal. • Down hole length is the distance down the inclination of the hole and is measured as the distance from the horizontal to end of hole. • Intercept depth is the distance from the start of the hole down the inclination of the hole to the depth of interest or assayed interval of interest.

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. •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. •The assumptions used for any reporting of metal equivalent values should be clearly stated. No new exploration results have been reported in this release. Metal equivalent values are not used in reporting.
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’). The majority of the Tabakoroni mineralisation is vertical. There is one domain which dips at 45oto the west. The majority of the drill holes are planned at a general inclination of -60 degrees east and as close to perpendicular to the ore zone as possible. At the angle of the drill holes and the dip of the ore zones, the reported intercepts will be slightly more than true width.
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. Relevant maps, diagrams and tabulations are included in the body of text.
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. Mineral Resources are being reported in this announcement. No new exploration results have been reported in this release.

Section 3 Estimation and Reporting of Mineral Resources

CRITERIA	JORC CODE EXPLANATION COMMENTARY
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. Data has been compiled into a relational SQL database; the setup of this database precludes the loading of data which do not meet the required validation protocols. The data is managed using DataShed© drill hole management software using SQL database techniques. Validation checks are conducted using SQL and DataShed© relational database standards. Data has also been checked against original hard copies for 100% of the data, and where possible, loaded from original data sources. Resolute completed the following basic validation checks on the data supplied prior to resource estimation: •Drill holes with overlapping sample intervals. •Sample intervals with no assay data or duplicate records. •Assay grade ranges. •Collar coordinate ranges. •Valid hole orientation data. There are no significant issues identified with the data.
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. Mrs Susan Havlin, an employee of Snowden Optiro Pty Ltd and a Member of the Australasian Institute of Mining and Metallurgy is the Competent Person who has visited this site in February and October 2019. All aspects of drilling, sampling and mining are considered by the Competent Persons to be of a high industry standard.
Geological interpretation	•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. The digital database used for the interpretation included logged intervals for the key stratigraphic zones of Tabakoroni. Detailed geological logs were available in hardcopy and digital and reviewed where necessary. There is a high level of confidence for the interpretation of the Tabakoroni Main Shear Zone (TMSZ) due to the close-spaced grade control drilling at surface and the confirmation of the position in the current oxide pits. Since an independent structural model was created there is high level of confidence in the geological interpretation of the minor lodes adjacent to the TMSZ. Wireframes used to constrain the estimation are based on drill hole intercepts and geological boundaries. All wireframes at Tabakoroni have been constructed to a 1g/t Au cut-off grade for shape consistency. The mineralisation in the TMSZ is generally quite consistent and drill intercepts clearly define the shape of the mineralised zones with limited options for large scale alternate interpretations.
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 mineral resource at Tabakoroni comprises four individual domains. The main zone is the TMSZ, which extends for approximately 1,800 metres along strike; the sub-vertical dipping gold mineralised zone width varies between 1.5 and 15 metres, with an average thickness of 5 metres. The Mineral Resource is limited in depth by drilling, which extends from surface to a maximum depth of approximately 450 metres vertically. There is a zone parallel to the TMSZ which is generally at depth and not as consistent; this is dominantly in the central part of the deposit. The northeast (NE) domain is a zone which is striking at 20° and is sub vertical in the north of the deposit. The southern lode is shallow westerly-dippinglodes in the southern and central

Estimation was completed in Datamine Studio RM using an Ordinary Kriged model to estimate the gold grade. Grades were estimated into parent block of 5 mE by 10 mN by 5 mRL with sub- celling down to 1mE by 2 mN by 1 mRL was employed for resolution of the mineralisation boundaries as defined by wireframes. The drill spacing at Tabakoroni varies from 12.5 by 12.5 metres for grade control to between 25 and 50 metres for the exploration holes.

Drillhole sample data was flagged using domain codes generated from three-dimensional mineralisation domains. The grade control samples and exploration samples were composited to 1 metre intervals.

Variogram orientations were largely controlled by the strike of the mineralisation and downhole variography. Variograms for estimation purposes were determined for each domain.

Kriging neighbourhood analysis was performed to optimise the block size, sample numbers and discretisation levels with the goal of minimising conditional bias in the gold grade estimates.

Mineralisation domains were treated as hard boundaries in the estimation process while oxidation surfaces were treated as soft boundaries for gold, sulphide sulphur and organic carbon. A hard boundary was utilised in the estimation of arsenic between fresh material and transitional material following a boundary analysis review.

Three search passes were used, with the first search pass set to the range of the variogram for each element. A minimum of 8 and a maximum of 30 samples were used. The search stayed the same for the second pass but was increased by a factor of 2 for the third and final pass. The minimum number of samples was reduced to 6 for the second pass and 4 for the third pass.

No deleterious elements were found in the ore.

No selective mining units have been assumed.

Top cuts were applied to reduce the variability of the data and to remove the outliers.

The estimated block model grades were visually validated against the input drillhole data and comparisons were carried out against the drillhole data and by northing and elevation slices. Global comparison between the input data and the block grades for each variable is considered acceptable (±10%).

Comparison with the mine production to date was carried out and was within an acceptable limit.

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 a green fields project, may not always be well advanced, the status of early consideration of these potential environmental impacts should be reported. Where these aspects have not been considered this should be reported with an explanation of the environmental assumptions made. It is a requirement of Decree No.03-594/P-RM of 31 December 2003 of Malian law that an Environmental and Social Impact Study (Étude d’Impact Environmental et Social – EIES) must be undertaken to update the potential environmental and social impacts of the mine’s redevelopment. The EIES for the Syama Gold Mine (including Tabakoroni) was approved in November 2007 and an Environment Permit (07- 0054/MEA – SG) was issued by the Ministry of Environment and Sanitation on 22 November 2007. The Ministry of Environment conducts timely reviews of the Syama Gold Mine to ensure that Company maintains compliance with the EIES guidelines. At Syama and Tabakoroni, there are three key practices for disposal of wastes and residues namely, stacking of waste rock from open pit mining; storage of tailings from mineral processes; and “tall-stack dispersion” of sulphur dioxide from the roasting of gold bearing concentrate. All waste disposal practices are in accordance with the guidelines in the EIES.

The Environmental and Social Impact Study – “Société des Mines de Syama, Syama Gold Mine, Mali”, dated 2007 indicated there was minimal potential for acid mine drainage from waste rock due to the elevated carbonate content which buffers a potential acid generation. Resolute maintains a plan for progressive rehabilitation of waste 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 is flotation tailings where the sulphide minerals have already been removed from the host rock. Its mineralogy includes 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 and dissipation of the sulphur dioxide is modelled daily to predict the need to pause the

He conducted a site visit to the project area in January 2022. Travel to site was restricted during the 2021 due to covid-19 travel restrictions, but weekly contact with site teams was maintained throughout the period.

The site visit reviewed the project site and proposed portal location in the mined out Namakan Pit western wall, a review of current operations at both Syama and Tabakoroni, existing open pit infrastructure available for immediate underground use, a review of selected drill core and various meetings were held with site personnel and key stakeholders to the study. A pit wall failure was noticed in the eastern wall of the Namakan pit. This failure was monitored since then through the past wet season and have stabilised at its natural angle of repose and does not pose further material risk to the proposed underground portal location.

Study status

• The type and level of study undertaken to enable Mineral Resources to be converted to Ore Reserves.

• The Code requires that a study to at least Pre-Feasibility Study level has been undertaken to convert Mineral Resources to Ore Reserves. Such studies will have been carried out and will have determined a mine plan that is technically achievable and economically viable, and that material Modifying Factors have been considered.

A Pre-Feasibility Study was completed on Tabakoroni Underground in late 2020.

Tabakoroni open pit has been in continuous mining operation since August 2018. During this time the performance of the open pit has shown a positive reconciliation between mineral resources and gold production and delivered positive cashflows. Data from the current open pit operations which also applies to the intended underground operation, such as existing infrastructure and ore haulage cost, were used as part of the underground study. The open pit reconciliation data was not considered as it relates to oxide ore only and the underground will focus on fresh ore only.

No underground operations have been undertaken at Tabakoroni yet. However, underground operations and processing of similar underground material have been undertaken for several years at the nearby Syama Mine where the Tabakoroni Underground ore will also be processed under the current toll treatment agreement, providing actual data to further support the Tabakoroni study assumptions.

Primary contributors to the study were:

• Optiro Pty Ltd – Mineral Resources.

• Solid Geology Pty Ltd – Structural Model.

• • AMC Consultants – mining geotechnical study and portal review.

• Piteau – dewatering.

• Digby Wells – environmental and social impact assessment.

• Outotec – backfill, concentrate roasting, floatation plant.

• Osprey – security assessment.

• Practara – economic evaluation.

• ALS – metallurgical variability testing.

• • Resolute Mining Ltd – mine design and scheduling, processing and overall study management.

• Cut-off • The basis of the cut-off grade(s) or quality parameters parameters applied.

A marginal cut-off grade (COG) of 2.5g/t gold has been applied for Tabakoroni Underground. This is based on long hole open stoping with paste fill at a gold price of U$1,500/oz, metallurgical recovery of 78%, and includes royalties of 6%.

Individual underground zones and levels were further tested to confirm each area achieves the required financial returns to offset the capital investment required to access that zone or level. Sub-economical areas were removed from the reserves.

• Mining factors or • The method and assumptions used as reported in the assumptions Pre-Feasibility or Feasibility Study to convert the Mineral Resource to an Ore Reserve (i.e. either by application of appropriate factors by optimization or by preliminary or detailed design).

• The choice, nature and appropriateness of the selected mining method(s) and other mining parameters including associated design issues such as pre-strip, access, etc.

• The assumptions made regarding geotechnical parameters (e.g. pit slopes, stope sizes, etc.), grade control and pre-production drilling.

• The major assumptions made and Mineral Resource model used for pit and stope optimization (if appropriate).

• The mining dilution factors used.

• The mining recovery factors used.

• Any minimum mining widths used.

• The manner in which Inferred Mineral Resources are utilized in mining studies and the sensitivity of the outcome to their inclusion.

• The infrastructure requirements of the selected mining methods.

The Tabakoroni mineralisation is mostly steeply dipping, between 80 to 90°, with an average width of 4m to 15m. Some mineralisation is located parallel to, and adjacent to the main Tabakoroni mineralisation. These shallower dipping zones are located predominantly in a competent basalt zone, ranging in dip between 40° and 80°, with an average width of 2m to 10m.

Long hole open stoping is considered the most suitable mining method to extract the underground deposit. Long term support will be providing by backfilling the stopes with cemented paste in the main mineralised zone, create by adding binder to a large supply of highly weathered oxide waste already available on site from the previous open pit mines. Shallower dipping zones in the competent basalt zones will also use open stoping with pillars, where appropriate.

Longitudinal sub-level caving and open stoping with rock fill were also reviewed but not considered appropriate methods. The mineralisation is too long and narrow to use sub-level caving and it would result in caving breaking through into the current open pit, increasing inrush risk for the underground. Paste fill was selected over waste fill as it provides a better cashflow with a top-down mining method, provides improved stability and in general there is a lack of suitable fresh rock to use as backfill material. It also improves the extraction of parallel mineralised zones which was not possible with open stopes and loose rock fill.

The reported Ore Reserve estimates for Tabakoroni are based on Deswik.SO (Mineable Shape Optimiser / MSO) results, followed by detailed mine design in Deswik.CAD and activity-based task and resource scheduling in Deswik.Sched. Economic modelling was performed in consultation with an external financial consultant experienced in Malian mining economic modelling.

Stope dilution is considered separately for hangingwall and footwall conditions as part of the MSO optimisation. Equivalent Linear Overbreak Slough (ELOS) is applied based on geotechnical domaining, resulting in 0.5m dilution in competent (basalt) ground to 2.0m in poor, highly structured zones. The average dilution considered is 0.5 to 1.0m, applied individually to both hangingwall and footwall conditions. A global mine recovery of 90% was applied.

Minimum Mining Width used was 3.0m, but average stoping widths range between 4.5m and 10.0m. Level spacings are selected at 20m vertical, floor to floor. Stope lengths of 10m to 50m are recommended based on the geotechnical modelling and chosen level spacing. The study conservatively limited stope lengths to 20m, which will be further optimised during actual operations. For the shallower dipping stopes a minimum footwall dip of 40° was selected to ensure blasted material can be moved effectively to the drawpoint for loading during production.

Costs are based on existing contract mining rates from the nearby Syama Operation with a contract proposal provided for the study to account for potential changes expected at Tabakoroni, contract haulage rates to the Syama process plant from the current Tabakoroni open pit operation, processing costs are based on the current Syama process plant and site costs which are understood with a high degree of accuracy from current operations.

Equipment for the underground were selected considering the selected mining method, planned production rate, existing experience and equipment in operation at Syama Underground. Loading will be done by 21t loaders from the development headings and stopes and hauled by 63t trucks to surface via a decline. From surface stockpiles ore will be hauled to the process plant at Syama using the current open pit truck haulage fleet and waste will dumped directly onto the existing open pit waste dumps.

The mine plan includes an insignificant amount of Inferred Resources, which is not material to the outcome of the Ore Reserves. Inferred Resources were considered when positioning life

of mine infrastructure but does not materially influence the outcome of the current reserves.

Existing open pit infrastructure and a dedicated haul road to Syama is available for immediate use by the underground operation. The only additional infrastructure consists of:

  - A power shed to house diesel generators for power generation. Existing diesel generators will be relocated from the current Syama operation as part of their power upgrades and the power shed is just for weather protection.

  - Paste plant for paste fill generation.

  - Explosives magazine (open pit operations did minimal blasting and did not establish an explosive magazine).

  - Underground primary ventilation fans.

  - Upgraded security control facilities.

  - Float circuit modifications to allow the existing Syama Oxide plant to process sulphide ore.

• For minerals that are defined by a specification, has the ore reserve estimation been based on the appropriate mineralogy to meet the specifications?

Metallurgical test work was conducted on multiple samples, representative of the spatial and mineralogical distribution of the deposit. The tests indicated that, similarly to the Syama ore, the Tabakoroni ore can be double refractory in nature due to locking of gold within the sulphides and organic carbon. Processing of the ore will be similar to that of the Syama sulphide circuit which has been in operation for several years and is well understood, consisting of the following stages:

• Crushing and grinding utilising the existing oxide process plant infrastructure

• Gravity gold recovery utilising the existing oxide gravity circuit

• Flotation to produce a sulphide rich concentrate through a new flotation circuit, prior to blending with the current Syama concentrate circuit for further:

• Concentrate thickening.

• Roasting, followed by calcine quench and wash.

• o Carbon-in-leach (CIL). o Tailings disposal.

The oxide crushing and grinding circuit has an oxide capacity of 1.5Mtpa, with a modelled sulphide throughput capacity of up to 1.0Mtpa. The Syama roaster, CIL circuit and tailings storage facility has enough capacity to process the additional concentrate.

A number of metallurgical test work programmes have been conducted on a range of Tabakoroni ore samples to date. The most recent variability test programme, conducted as part of the PFS, focussed on optimising the flowsheet to then assess the metallurgical performance of the various mineralised domains to be encountered. A total gold recovery of 83% has been assumed based on test results to date. This is in line with similar ore being processed at Syama.

Environmental • The status of studies of potential environmental impacts of the mining and processing operation. Details of waste rock characterization and the consideration of potential sites, status of design options considered and, where applicable, the status of approvals for process residue storage and waste dumps should be reported.

The Tabakoroni mining area and haul road to Syama are covered under current environmental approval and permitting. An ESIA update and approval for the changes brought about by the new underground operation is currently being conducted by an experienced local consultant as per Malian regulations, with external specialist consulting input where required. The ESIA only considers the changes due to the existing Tabakoroni operation going underground as the current open pit operations and processing at Syama is already covered under existing approvals (Refer Section 3). A draft ESIA report for the changes has been submitted for approval and is pending government approval. No reasons are known to the Competent Person why this approval will not be granted.

An active waste rock characterisation program has been put in place for Tabakoroni open pit operation. Underground waste will be co-disposed underground with paste fill where possible, with the remainder being stored on the current open pit waste dump under the current waste rock management protocols to prevent potentially acid forming waste rock from contaminating water sources. The current waste dump has much more space than is required by the underground operation.

Ore Reserves from Tabakoroni will be processed at Syama and tailings storage will be impounded in existing footprint area approved in the current ESIA. Progressive raising of the tailings occurs regularly with the 9th lift completed in 2019. Routine progress on the monitoring is reported to government and at stakeholder meetings in concert with routine inspections by government representatives.

Arsenic is naturally occurring in the Tabakoroni mineralisation. A groundwater characterisation programme was conducted as part of the ESIA submission and did not identify any adverse impacts on water being discharged to the environment.

All required mining infrastructure is already in place at the Tabakoroni open pit mine and processing and camp facilities at Syama Mine, except for the additions required specifically for the Tabakoroni underground, consisting of:

• A power shed to house diesel generators for power generation. Existing diesel generators will be relocated from the current Syama operation as part of their power upgrades.

• • Paste plant for paste fill generation.

• Explosives magazine.

• Upgraded security control facilities.

• Minor fit-out to the existing open pit offices and workshops to comply with underground requirements, such as change rooms and lamp rooms.

• Float circuit modifications to allow the existing Syama Oxide plant to process Tabakoroni sulphide ore.

Tabakoroni is linked to the Syama Mine through a purpose built 35km haul road. The Syama Mine is located near the two major towns of Kadiola and Sikasso. Kadiola, 55km southeast, is the regional capital while Sikasso, approximately 85km to the northeast, is the second largest city in Mali and located close to the border with Burkina Faso.

Access is via formed gravel road off the sealed Sikasso to Côte d’Ivoire highway through Kadiola, and then from Fourou to site. Most consumables and supplies use this route as it can be approached either from Côte d’Ivoire through the border post at Zegoua or alternatively from Burkina Faso and Togo through Sikasso. The road north through Bananso to Farakala, on the main highway from Bamako to Sikasso, provides an alternate and shorter route to Bamako. This road is generally impassable during the wet season when the low level “bridge” at Bananso is covered with water.

The 70km section of road from Kadiola to the site was upgraded for the Syama Mine. In addition to the current open pit infrastructure left behind by open pit operations at Tabakoroni, the Syama Mine provides access to administration buildings, plant site buildings and accommodation for housing expatriate and senior national staff.

Tabakoroni site is serviced through a local telecommunications provider Orange. Provision is made in the study to allow have a dedicated link to Syama Mine, from where two Internet and mobile telecommunications providers (Sotelma & Orange) are available, in addition to a point to point satellite connection to Perth.

COMMENTARY

Cost estimates are based mostly on existing operations at Syama and Tabakoroni, with modifications where identified in the study. Current operations, and existing costs were used for:

• Ore haulage to Syama for processing under the current open pit haulage contract.

• Owner-operated processing, general and administration costs are shared between the oxide plant and the sulphide plant at Syama, which processes the current Syama UG orebody. These costs are well understood, and minor changes were included based on Tabakoroni specific metallurgical variability test work results.

• Power generation cost utilising the current Syama diesel generators.

• Development and production rates are based on the current Syama mining contract schedule of rates, with updated quotes provided by the contractor as required for mining method changes expected at Tabakoroni.

• Ground support consumables, fuel, explosives, bulk cement based on current Syama mining contract.

• Mine closure costs (existing open pit component).

• PFS level cost estimates were calculated for:

• Paste fill cost – based on locally supplied bulk cement prices and an independent paste fill study to determine consumption rate.

• Environmental and mine closure costs specific to underground.

The oxide plant produces gold doré (without problematic deleterious elements) that is subsequently refined offsite. Refining costs are allowed for as per current Syama Mine, but are not material.

Drilling at Syama was conducted within the Malian Exploitation Concession Permit PE 93/003 which covers an area of 200.6km2. Resolute Mining Limited has an 80% interest in the Syama project and the Exploitation Permit PE 93/003, on which it is based, through its Malian subsidiary, Sociêtê des Mines de Syama SA (SOMISY). The Malian Government holds a free carried 20% interest in SOMISY. The Permits are held in good standing. Malian mining law provides that all Mineral Resources are administered by DNGM (Direction Nationale de la Géologie et des Mines) or National Directorate of Geology and Mines under the Ministry of Mines, Energy and Hydrology.
Exploration done by other parties • Acknowledgment and appraisal of exploration by other parties. The Syama deposit was originally discovered by a regional geochemical survey undertaken by the Direction National de Géologie et des Mines (DNGM) with assistance from the United Nations Development Program (UNDP) in 1985. There had also been a long history of artisanal activities on the hill where an outcropping chert horizon originally marked the present-day position of the open pit. BHP during 1987-1996 sampled pits, trenches, auger, RC and diamond drill holes across Syama prospects. Randgold Resources Ltd during 1996-2000 sampled pits, trenches, auger, RAB, RC and diamond drill holes across Syama prospects. Etruscan Resources Inc explored Tabakoroni during 2002- 2003 by auger, aircore, RC and diamond drill hole tails. The Tabakoroni area was previously explored Barrick Gold (1990) by auger, pits, trenches, RAB and diamond core drilling.
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 the southern 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 a narrow belt of interbedded basalt and argillite. The Kadiolo terrane comprises polymictic conglomerate and sandstone 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 volcano- sedimentary units of the Syama Formation. The major commodity being sought is gold.

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: o easting and northing of the drill hole collar o elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar o dip and azimuth of the hole o down hole length and interception depth o Whole 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. All information, including easting, northing, elevation, dip, azimuth, coordinate system, drill hole length, intercept length and depth are measured and recorded in UTM Zone 29 WGS84. The Syama belt is mostly located on the Tengrela 1/200,000 topo sheet (Sheet NC 29-XVIII). Spectrum Survey & Mapping from Australia established survey control at Tabakoroni using AusPos online processing to obtain an accurate UTM Zone 29 (WGS84) and ‘above geoid’ RL for the origin of the survey control points. Accuracy of the survey measurements is considered to meet acceptable industry standards. Drill hole information has been tabulated for this release in the intercepts table of the accompanying text. For completeness the following information about the drill holes is provided: •Easting, Northing and RL of the drill hole collars are measured and recorded in UTM Zone 29 (WGS84). •Dip is the inclination of the drill hole from horizontal. A drill hole drilled at -60° is 60° from the horizontal. •Down hole length is the distance down the inclination of the hole and is measured as the distance from the horizontal to end of hole. •Intercept depth is the distance from the start of the hole down the inclination of the hole to the depth of interest or assayed interval of interest.
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. • 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. • The assumptions used for any reporting of metal equivalent values should be clearly stated. Exploration results are tabulated using the following parameters: •Grid coordinates are WGS84 Zone 29 North. •Cut-off grade for reporting of intercepts is >=1g/t Au. •No top cut of individual assays prior to length weighted compositing of the reported intercept has been applied. •Maximum 3m consecutive internal dilution included within the intercept. Metal equivalent values are not used in reporting.
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’). The Cashew NE, and Paysans mineralisation is shallowly dipping at about 30 degrees to the west (local grid). The majority of the Tellem mineralisation is narrow and sub vertical. The majority of the drill holes are planned at a general inclination of -60 degrees east and as close to perpendicular to the ore zone as possible. At the angle of the drill holes and the dip of the ore zones, the reported intercepts will be slightly more than true width.
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. No exploration results have been reported in this release.

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.		Cashew NE,Paysans and Tellem Data has been compiled into a relational SQL database; the setup of this database precludes the loading of data which do not meet the required validation protocols. The data is managed using DataShed© drill hole management software using SQL database techniques. Validation checks are conducted using SQL and DataShed© relational database standards. Data has also been checked against original hard copies for 100% of the data, and where possible, loaded from original data sources. Resolute completed the following basic validation checks on the data supplied prior to resource estimation: •Drill holes with overlapping sample intervals. •Sample intervals with no assay data or duplicate records. •Assay grade ranges. •Collar coordinate ranges. •Valid hole orientation data. There are no significant issues identified with the data.

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.

Cashew NE and Paysans Mr Bruce Mowat, a full-time employee of Resolute Mining Ltd and a Member of the Australasian Institute of Mining and Metallurgy is the Competent Person who has visited this site multiple times. Tellem Mr Nicholas Johnson, as employee of MPR Geological Consultants Pty Ltd and a Member of the Geological Institute of Geoscientists is the Competent Person who has visited this site on numerous occasions, the most recent being May 2014 to review the grade control protocols ad review the Mineral Resource estimates at Syama. All aspects of drilling, sampling and mining are considered by the Competent Persons to be of a high industry standard.

Geological interpretation • 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.

Cashew NE and Paysans The digital database used for the interpretation included logged intervals for the key stratigraphic zones of Cashew NE, Paysans and Tellem. Detailed geological logs were available in hardcopy and digital and reviewed where necessary. Wireframes used to constrain the estimation are based on drill hole intercepts and geological boundaries. All wireframes at Cashew NE and Paysans have been constructed to a 0.3g/t Au cut-off grade for shape consistency. At Tellem they were constructed at nominal 0.1g/t Au mineralised envelope. There is a moderate level of confidence for the interpretation at Cashew NE, Paysans, and Tellem due to the relatively close- spaced drilling at surface. The mineralisation is generally quite consistent and drill intercepts clearly define the shape of the mineralised zones with limited options for large scale alternate interpretations.

Cashew NE

Estimation was completed in Datamine Studio RM using an Ordinary Kriged model to estimate the gold, sulphide sulphur and organic carbon grades. Grades were estimated into parent block of 5mE by 5mN by 2.5mRL with sub- celling down to 2.5mE by 2.5mN by 2.5mRL was employed for resolution of the mineralisation boundaries as defined by wireframes. The drill spacing at Cashew is a nominal 25 by 25 metres for the exploration holes for the majority of the deposits and 50 by 50 metres around the periphery. The main part of the deposit has been gc drilled out to 12.5 by 5 metres.

Drillhole sample data was flagged using domain codes generated from three-dimensional mineralisation domains. The samples were composited to 1 metre intervals.

Variogram orientations were largely controlled by the strike of the mineralisation and downhole variography. One set of variograms was generated for all the mineralisation due to similar orientation of each of the domains.

Kriging neighbourhood analysis was performed to optimise the block size, sample numbers and discretisation levels with the goal of minimising conditional bias in the gold grade estimates.

The mineralisation domains were treated as hard boundaries in the estimation process while oxidation surfaces were treated as soft boundaries.

Three search passes were used, with the first search pass set to the range of the variogram for each domain. A minimum of 8 and a maximum of 30 samples were used. The search stayed the same for the second pass but was increased by a factor of 2 for the third and final pass. The minimum number of samples was reduced to six for the second pass and for the third pass.

No deleterious elements were found in the ore.

No selective mining units have been assumed.

Top cuts were applied to reduce the variability of the data and to remove the outliers.

The estimated block model grades were visually validated against the input drillhole data and comparisons were carried out against the drillhole data and by northing and elevation slices. Global comparison between the input data and the block grades for each variable is considered acceptable (±10%)

Paysans

Estimation was completed in Datamine Studio RM using an Ordinary Kriged model to estimate the gold grade. Grades were estimated into parent block of 10mE by 20mN (at Cashew, 25mN at Paysans) by 5mRL with sub- celling down to 2.5mE by 2.5mN by 2.5mRL was employed for resolution of the mineralisation boundaries as defined by wireframes. The drill spacing at Paysans is a nominal 25 by 25 metres for the exploration holes for the majority of the deposits and 50 by 50 metres around the periphery.

Drillhole sample data was flagged using domain codes generated from three-dimensional mineralisation domains. The samples were composited to one metre intervals.

Variogram orientations were largely controlled by the strike of the mineralisation and downhole variography. One set of variograms was generated for all the mineralisation due to similar orientation of each of the domains and sometimes lack of composites. Kriging neighbourhood analysis was performed to optimise the block size, sample numbers and discretisation levels with the goal of minimising conditional bias in the gold grade estimates.

At Cashew mineralisation domains were treated as hard boundaries in the estimation process while oxidation surfaces were treated as soft boundaries. At Paysans the mineralisation

domains were treated as hard boundaries as well as the boundary between the transitional and fresh material within each domain.

The boundary between the oxide and transitional is treated as a soft boundary. Three search passes were used, with the first search pass set to the range of the variogram for each domain. A minimum of eight and a maximum of 30 samples were used. The search stayed the same for the second pass but was increased by a factor of three for the third and final pass. The minimum number of samples was reduced to six for the second pass and four for the third pass.

No deleterious elements were found in the ore.

No selective mining units have been assumed.

Top cuts were applied to reduce the variability of the data and to remove the outliers.

Global comparison between the input data and the block grades for each variable is considered acceptable (±10%).

Tellem

Multiple Indicator Kriging (MIK) with block support adjustment to estimate gold resources into blocks with dimensions of 10mE by 25mN by 5mRL. MIK of gold grades used indicator variography based on the two metre resource composite sample grades. Gold grade continuity was characterised by indicator variograms at 14 indicator thresholds spanning the global range of grades. A block support adjustment was used to estimate the recoverable gold resources at each deposit. The shape of the local block gold grade distribution has been assumed lognormal and an additional adjustment for the “Information Effect” has been applied to arrive at the final Mineral Resource estimates.

MIK was used as the preferred method for estimation of gold resources at Tellem as the approach has been demonstrated to work well in a large number of deposits of diverse geological styles. The gold mineralisation seen at the Tellem deposit is typical of that seen in most structurally controlled gold deposits where the MIK method has been found to be of most benefit.

Data viewing, compositing and wire-framing were performed using Micromine software. Exploratory data analysis, variogram calculation and modelling, and resource estimation have been performed using FSSI Consultant (Australia) Pty Ltd GS3M software. GS3M is designed specifically for estimation of recoverable resources using MIK methodology.

The sample data set containing all available assaying were composited to two metre intervals each located by their mid-point co-ordinates and assigned a length weighted average gold grade. The composite length of two metres was chosen because it is a multiple of the most common sampling interval (1.0 metre) and is also an appropriate choice for the kriging of gold into the model blocks where open pit mining is undertaken on 2.5 metre benches.

Block dimensions are 10mE by 25mN by 5mRL and was chosen as it approximates the average drill hole spacing in the horizontal direction, with the 5m elevation being a multiple of the mining bench height of 2.5m. The interpolation utilised a 3 pass octant search strategy with search radii generally in the order of category 1 searching 15m in the x, 25m in the y and 15m in the z direction, 16 minimum composites used, a maximum of four composites per octant and a minimum of four octants with data.

Category 2 uses a 50% search distance increase but otherwise the same parameters and category 3 uses the same search distance as category 2 but only requires eight minimum composites and only 2 octants require data. The search ellipse on each category is consistently orientated orthogonal to

		modelling grid. The 2m resource composites were initially coded by the mineralisation domain interpretation and the resultant primary domain coding further subdivided using the weathering surfaces to form sub-domains. Sample composites in each primary and sub- domain combination were reviewed for their univariate and indicator statistics and spatial continuity and were the basis of grade modelling. A combination of outlier high grade composites being ignored for each sub-domain for the generation of the indicator statistics, and selection of the median instead of mean for the highest indicator threshold were used to guard against a few higher grades within the population from having a disproportional influence on the gold estimation. A block support adjustment was used to estimate the recoverable gold resources. The shape of the local block gold grade distribution has been assumed lognormal and an additional adjustment for the “Information Effect” has been applied to arrive at the final Resource estimates.

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. Where this is the case, this should be reported with an explanation of the basis of the mining assumptions made.		Cashew NE, Paysans, and Tellem The Resource models assume that a moderate level of mining selectivity is achieved in open pit mining. It has been assumed that high quality grade control will be applied to ore/waste delineation processes using RC drilling, or similar, at a nominal (and no greater) spacing of 5 metre by 12.5 metre and applying a pattern sufficient to ensure adequate coverage of the mineralisation zones. This is consistent with current mining practises at Syama.

• Environmental • Assumptions made regarding possible waste and process Cashew NE, Paysans, and Tellem factors or residue disposal options. It is always necessary as part assumptions 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 a green fields project, may not always be well advanced, the status of early consideration of these potential environmental impacts should be reported. Where these aspects have not been considered this should be reported with an explanation of the environmental assumptions made.

It is a requirement of Decree No.03-594/P-RM of 31 December 2003 of Malian law that an Environmental and Social Impact Study (Étude d’Impact Environmental et Social – EIES) must be undertaken to update the potential environmental and social impacts of the mine’s redevelopment. The EIES for the Syama Gold Mine (including Tabakoroni) was approved in November 2007 and an Environment Permit (07- 0054/MEA – SG) was issued by the Ministry of Environment and Sanitation on 22 November 2007. The Ministry of Environment conducts timely reviews of the Syama Gold Mine to ensure that the Company maintains compliance with the EIES guidelines.

At Syama, there are three key practices for disposal of wastes and residues namely, stacking of waste rock from open pit mining; storage of tailings from mineral processes; and “tall-stack dispersion” of sulphur dioxide from the roasting of gold bearing concentrate. All waste disposal practices are in accordance with the guidelines in the EIES.

The Environmental and Social Impact Study – “Société des Mines de Syama, Syama Gold Mine, Mali”, dated 2007 indicated there was minimal potential for acid mine drainage from waste rock due to the elevated carbonate content which buffers a potential acid generation. Resolute maintains a plan for progressive rehabilitation of waste 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 is flotation tailings where the sulphide minerals have already been removed from the host rock. Its mineralogy includes 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 50ppm 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 and dissipation of the sulphur dioxide is modelled daily to predict the need to pause the roasting process to meet the air quality criteria set out in the Environmental and Social Impact Study.

Classification • The basis for the classification of the Mineral Resources into varying confidence categories. • Whether appropriate account has been taken of all relevant factors (i.e. 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.		Cashew NE and Paysans The Indicated Mineral Resource classification is based on moderate confidence in the geology and gold grade continuity with 25m x 25m spaced drillhole density or less. The Inferred Mineral Resource classification is applied to extensions of mineralised zones on the margins of the deposit where drill spacing is more than 50m x 50m and the extents of mineralisation at depth. The validation of the block model has confirmed satisfactory correlation of the input data to the estimated grades and reproduction of data trends. Tellem The Resource model uses a classification scheme producing a resource code based on the number and location of gold composites used to estimate proportions and gold grade of each block. This is based on the principle that larger numbers of composites, which are more evenly distributed within the search neighbourhood, will provide a more reliable estimate. The strategy adopted in the current study uses category 1 and 2 from the 3 pass octant search strategy as Indicated and category 3 as Inferred. This results in a geologically sensible classification whereby Category 1 and 2 are surrounded by data in close proximity. Category 3 blocks may occur on the peripheries of drilling but are still related to drilling data within reasonable distances. The Mineral Resource estimates appropriately reflects the view of the Competent Persons.
Audits or reviews • The results of any audits or reviews of Mineral • Resource estimates.		Cashew NE, Paysans, and Tellem There has been no external review of the Mineral Resource estimate.
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.		Cashew NE, Paysans, and Tellem The Mineral Resource estimate has been classified based on the quality of the data collected, the density of data, the confidence of the geological models and mineralisation models, and the grade estimation quality. This has been applied to a relative confidence based on data density and zone confidence for resource classification. No relative statistical or geostatistical confidence or risk measure has been generated or applied. The relative accuracy of the Mineral Resource estimate is reflected in the reporting of Indicated and Inferred 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. No production data available for comparison.

Section 4 Estimation and Reporting of Ore Reserves

CRITERIA	JORC CODE EXPLANATION COMMENTARY
Mineral Resource estimate for conversion to Ore Reserves	• Description of the Mineral Resource estimate used as a basis for the conversion to an Ore Reserve. • Clear statement as to whether the Mineral Resources are reported additional to, or inclusive of, the Ore Reserve. Resources at Porphyry Zone are reported above a 1g/t cut-off. This was calculated as a marginal cut-off utilising open pit mining methods. Material below this cut-off is not included in the Mineral Resource. Ore Reserves are the material reported as a sub-set of the resource, that which can be extracted from the mine and processed with an economically acceptable outcome. Mineral Resources are reported inclusive of Ore Reserves.
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. Mr Kitwa Ndjibu is member of the Australasian Institute of Mining and Metallurgy and is a Competent Person who has visited the site the project is located.
Study status	• The type and level of study undertaken to enable Mineral Resources to be converted to Ore Reserves. • The Code requires that a study to at least Pre-Feasibility Study level has been undertaken to convert Mineral Resources to Ore Reserves. Such studies will have been carried out and will have determined a mine plan that is technically achievable and economically viable, and that material Modifying Factors have been considered. The Porphyry Zone deposit is adjacent to the Tabakoroni mine which had a Feasibility study was completed in 2009 with updates in 2012 and 2016. Tabakoroni has been in continuous mining operation since August 2018. During this time the performance the project has shown a positive reconciliation between mineral resources and gold production and delivered positive cashflows.
Cut-off parameters	• The basis of the cut-off grade(s) or quality parameters applied. A cut-off of 0.8 g/t has been applied for Tabakoroni Oxide ore.
Mining factors or assumptions	• The method and assumptions used as reported in the Pre-Feasibility or Feasibility Study to convert the Mineral Resource to an Ore Reserve (i.e. either by application of appropriate factors by optimization or by preliminary or detailed design). • The choice, nature and appropriateness of the selected mining method(s) and other mining parameters including associated design issues such as pre-strip, access, etc. • The assumptions made regarding geotechnical parameters (e.g. pit slopes, stope sizes, etc.), grade control and pre-production drilling. • The major assumptions made and Mineral Resource model used for pit and stope optimization (if appropriate). • The mining dilution factors used. • The mining recovery factors used. • Any minimum mining widths used. • The manner in which Inferred Mineral Resources are utilized in mining studies and the sensitivity of the outcome to their inclusion. • The infrastructure requirements of the selected mining methods. The reported Ore Reserve estimate for Porphyry Zone is based on pit optimisations conducted using the Lerchs-Grossman (LG) algorithm of the Whittle software to calculate the optimal pit at specific input parameters and pit designs. Costs are based on existing contract mining and haulage rates and site costs which are understood with a high degree of accuracy. Mining is undertaken by conventional open pit methods of drill and blast, followed by load and haul, utilising mining equipment comprising 120t – 230t diesel hydraulic excavators and 90t off- highway dump trucks. Detailed pit design work was completed based on pit optimisations using Whittle Four-X optimisation software. Only Indicated Resources were used in the pit optimisation. Pit slope parameters for Porphyry Zone were based on a geotechnical assessment that included a total of seven specific geotechnical holes. Overall slopes angles are approximately 40°. All other pits adopt similar overall slope angles. Grade control consists of RC drilling, based on a 5.0mE x 12.5mN drill pattern The MIK resource estimation technique used for the Porphyry Zone implicitly incorporates internal mining dilution at the scale of the assessed SMU so no additional modifying factor was applied.

Processing is by conventional primary crushing followed by single stage SAG milling. Gold recovery is by means of a gravity recovery circuit and carbon in leach process. Processing recoveries used are 90%, 80% and 65% for Oxide, Transitional and fresh material respectively Mine is operational with good reconciliation between predicted recoveries and actual Allowances are made in the recovery estimates for transitional and fresh ore as the Au recovery is impacted by some of the gold being hosted in refractory sulphide and preg-robbing carbon.
Environmental	• The status of studies of potential environmental impacts of the mining and processing operation. Details of waste rock characterization and the consideration of potential sites, status of design options considered and, where applicable, the status of approvals for process residue storage and waste dumps should be reported. An active waste rock characterisation program has been put in place for Porphyry Zone. Ore Reserves from Porphyry Zone will be processed at Syama and tailings storage will be impounded in existing footprint area approved in the Environmental & Social Impact Study. Progressive raising of the tailings occurs regularly with the 9th lift completed in 2019. Routine progress on the monitoring is reported to government and at stakeholder meetings in concert with routine inspections by government representatives.
Infrastructure	• The existence of appropriate infrastructure: availability of land for plant development, power, water, transportation (particularly for bulk commodities), labour, accommodation; or the ease with which the infrastructure can be provided, or accessed. All required infrastructure is already in place for the Porphyry Zone deposit which is within the current the Tabakoroni mine footprint
Costs	• The derivation of, or assumptions made, regarding projected capital costs in the study. • The methodology used to estimate operating costs. • Allowances made for the content of deleterious elements. • The derivation of assumptions made of metal or commodity price(s), for the principal minerals and co- products. • The source of exchange rates used in the study. • Derivation of transportation charges. • The basis for forecasting or source of treatment and refining charges, penalties for failure to meet specification, etc. • The allowances made for royalties payable, both Government and private. The Porphyry Zone deposit is adjacent to the Tabakoroni mine, with established mining operations. Ore is trucked to Syama where it is processed at Syama’s oxide circuit. General and administration costs are shared between the oxide plant and the sulphide plant which treats the Syama UG orebody. The Porphyry Zone deposit will be mined contemporaneously with the Tabakoroni pits using the same mining and haulage fleet. The mining and haulage rates are based on known contract rates. The oxide plant produces gold doré (without problematic deleterious elements) that is subsequently refined offsite. Refining costs are not material. Exchange rates used for planning purposes are from consensus forecasts provided by external corporate advisers. Ad valorem Government royalties of 6% are payable on gold production.

Section 1 Sampling Techniques and Data

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. Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. 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. Sampling has been by diamond drill coring and reverse circulation chip techniques with minor trench and surface sampling. Diamond core is geologically logged and sampled to geological contacts with nominal sample lengths between 0.3m and 4.5m (most commonly 1.5m). Core selected for assay is systematically cut lengthwise into half core by diamond blade rock saw, numbered and bagged before dispatch to the laboratory for analysis. All core is photographed, wet and dry. Reverse circulation chips are geologically logged and sampled on regular lengths of 1m. Chip material selected for assay is systematically divided to a 1/8 proportion using a rotary splitter attached to the cyclone sample recovery system, numbered and bagged before dispatch to the laboratory for 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.). Diamond core drilling with standard inner tubes. NTW diameter (57.1 mm) to target depth where possible with some smaller NQ2 intervals as tails. Core is marked and oriented. Reverse Circulation drilling with 4” or 4.5” hammer and 4” rod string to target depth.
Drill sample recovery • • •	Method of recording and assessing core and chip sample recoveries and results assessed. Measures taken to maximise sample recovery and ensure representative nature of the samples. 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. Diamond core recoveries are measured in the core trays and recorded as recovered metres and recovered % as part of the geological logging process. Diamond core drilling prior to the latest deep diamond drilling had just over 96% of core sample intervals measured (28,701 measurements totalling 46,200m of core) with core recoveries of 75% or better. Approximately 85% of core sample intervals measured had core recoveries of 100%. The percentage core recovery data was examined graphically against the gold grades and Cube established that no relationship is evident between core loss and gold grade in the regions of low core recovery. In 2016 % core recovery data was examined graphically against the gold grades and no relationship is evident between core loss and gold grade in the regions of low sample recovery. RC recoveries are monitored by chip sample weight recording. Of 43 RC holes reviewed by Cube in 2016 all recorded weight/m in consolidated rock material ranged from 19 to 38kg/m (mode=25; mean=25; median=25kg/m) which equates to rock densities between 2 and 3gcm3.
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. Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc.) photography. The total length and percentage of the relevant intersections logged. Diamond core has been geologically and geotechnically logged to a level of detail to support appropriate classification and reporting of a Mineral Resource. Reverse circulation chip samples have been geologically logged to a level of detail to support appropriate classification and reporting of a Mineral Resource. Total length of DD logged data is 69,728.01m from total 70,527.01m drilled.
Sub-sampling techniques and •	If core, whether cut or sawn and whether quarter, half or all core taken. Core is systematically cut lengthwise into half core with a diamond saw.

sample preparation • • • • •	If non-core, whether riffled, tube sampled, rotary split, etc. and whether sampled wet or dry. For all sample types, the nature, quality and appropriateness of the sample preparation technique. Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. 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. Whether sample sizes are appropriate to the grain size of the material being sampled. In the initial drill phases between 2kg and 6kg of broken core sample was dispatched by contracted truck transport to SGS Mali (Phase 1- 90 holes) or ALS Mali (Phases 2 and 3 – 88 holes) for sample preparation. More recent samples (Phase 3 to 5 and the 2018 deep diamond holes) have undergone sample preparation at the site sample prep laboratory. The 2018 deep diamond programme (PWD362 to 420) was prepared onsite with assay pulps analysed by ALS Loughrea (Ireland). RC samples representing a 1/8 split are taken directly from the rig mounted cyclone by rotary splitter, sample weight is recorded, sample is bagged in pre numbered plastic and sample tickets are inserted and bag is sealed for transport to preparation facility. Generally, one of each of the two control samples (blank or CRM standard) is inserted into the sample stream every tenth sample. Over the 2018 deep diamond programme A total of 4,582 samples have had 249 CRM and 260 blanks inserted, sufficient as per industry standards. An industry standard, documented process of sample mark-up, core splitting, bagging and ticketing and recording is in place at the Mako site. The laboratories sample preparation followed a standard documented process flow with whole sample crushing (better than 70% passing 2mm) followed by a 1kg riffle split for pulverisation to 75 micron (better than 85% pass). Master pulps of 250g were split and placed in airtight, sealed bags and sent by courier to the assaying laboratory for analysis. For the majority of the Phase 1 drilling the mineralised interval sample preparation done at SGS Mali has been repeated and re- assayed. As a result the nature, quality and appropriateness of the sample preparation technique are to industry standard. Sample size of 2-6kg is appropriate for the grain size of material.
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. For geophysical tools, spectrometers, handheld XRF instruments, etc., the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. 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. Au assays are determined by fire assay with AAS finish. Laboratory and assay procedures are appropriate for Mineral Resource estimation. QAQC consisted of standards, blanks and laboratory duplicates (both coarse and pulp). The QAQC sample results showed acceptable levels of accuracy and precision. The assay data is considered by Cube to be suitable for Mineral Resource estimation.
Verification of sampling and assaying • • • •	The verification of significant intersections by either independent or alternative company personnel. The use of twinned holes. Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. Discuss any adjustment to assay data. All aspects of the core sampling, assay procedures and QA/QC program have been reviewed by Cube and were judged to be of industry standard and suitable for use in the estimation of Mineral Resources. Independent sampling has been undertaken by Cube and the results closely match the original data. Drill hole assay result data has been checked against the original hardcopy laboratory assay reports by Cube for a representative number of holes. Cube has in 2014 undertaken site based checks of the raw assay data to verify grade intersections were consistent with a visual inspection of mineralisation in the core. Below detection limit values (negatives) have been replaced by background values.

	Un-sampled intervals have been retained as un-sampled (null or blank). The majority of these intervals occur within the waste domain and have no material impact on the estimate.
Location of data points • • •	Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. Specification of the grid system used. Quality and adequacy of topographic control. Drill holes have been surveyed by a contract surveyor (P.C. Drysdale Land and Engineering Surveyor) using a Leica GS12 GNSS (GPS) survey system. Down hole surveys were undertaken by the drilling contractor using a Reflex Ex-Trac tool with a reading taken approx. every 50m down the hole. During the August 2018 site visit Cube made independent verification of the collar surveys of three diamond core in progress holes (PWD409, 408 and 407) which were all found to be within an acceptable tolerance of the planned and reported coordinates. Cube also verified the coordinated positions of laid out grade control planned holes on the pit floor. Grid system is based on the UTM28N grid on the WGS84 ellipsoid. Survey heights are based on PRS097 (with independent checks on AusPos) and are orthometric (i.e. msl). A topographic surface was provided based on a one metre resolution satellite DTM surface of Central Mako, including the Petowal prospect area, and a number of smaller resolution (10m x 10m) data files derived from the one metre source data. Cube utilised the smaller resolution data (10m x 10m) for all validation and estimation purposes.
Data spacing and distribution • • •	Data spacing for reporting of Exploration Results. 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. Whether sample compositing has been applied. Data spacing is variable being in the range of 80m x 40m to 20m x 20m. Additionally, a significant area of grade control drilling at 10m x 10m has been completed defining a volume of approximately four million BCM. This spacing is adequate to determine the geological and grade continuity for reporting of Measured, Indicated and Inferred Mineral Resources. Drill samples were composited to 3m for use in the estimate.
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. 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. The drill hole orientation was designed to intersect the mineralisation orthogonal to dip and strike of the major mineralisation bodies. The majority of drill hole azimuths were between 140° and 160⁰ with dips varying from -50 to -80⁰ below horizontal. For a small number of holes, different orientations were selected to target different portions of the mineralisation depending on localised mineralised structures or features. The preliminary RC grade control programme drilling was all vertical (azimuth of 0⁰ and dip of -90⁰). Mine grade control during 2017 and 2018 was primarily drilled on azimuth 140⁰ dipping -60⁰. Drilling primarily targeted the FEL unit which contained the most significant mineralisation and dipped at about 20-30⁰ to the northwest near surface, steepening to about 45⁰ dip at depth. The drilling orientation is adequate for a non-biased assessment of the orebody with respect to interpreted structures and interpreted controls on mineralisation.
Sample security •	The measures taken to ensure sample security. Labelling and submission of samples complies with industry standard.
Audits or reviews •	The results of any audits or reviews of sampling techniques and data. An independent audit of the sample preparation laboratory has been undertaken in 2018 (Fis, 2018) and the review undertaken at the project by Cube in August 2018 and both found no material issues with the sampling methods or data.

The influence of extreme gold assays has been reduced by topcutting across selected domains. Top-cuts have been determined using a combination of log probability, log histogram, and meanvariance plots. Top-cuts have been reviewed and applied to the composites on a domain-by-domain basis.

Variography has been determined using Datamine Supervisor v.8.14 software using top-cut values. Where there is insufficient data in individual domains to generate meaningful variograms, domains have been grouped, or variograms borrowed from other similar domains.

Drillhole data spacing ranges from 10m spacing in areas of dense drilling to approximately 100m spacing in sparsely drilled, deeper areas.

The block model parent block size is 5m (X) by 10m (Y) by 5m (Z) with sub-blocks down to 0.3125m (X) by 0.625m (Y) by 0.3125m (Z), with the sub-blocks estimated at the scale of the parent block. The block size is considered appropriate for the drillhole spacing throughout the deposit.

Grade estimation has been completed in three passes:

• ➢ Pass 1 estimation has been undertaken using a minimum and maximum number of sample composites (determined using Datamine Supervisor v.8.14 KNA tool) into a search ellipsoid with dimensions equal to half the variogram range of the domain.

• ➢ Pass 2 estimation has been undertaken with the same minimum/maximum samples as Pass 1 into a search ellipsoid twice the first pass.

• ➢ Pass 3 estimation has been undertaken with a minimum of 4 samples, and the same maximum number of samples as the first two passes into a search ellipsoid twice the second pass

• ➢ A four drillhole limit has been applied to the passes.

Previous Mineral Resource estimates are comparable in size and scope when considering the additional extensional drilling included in the current estimate.

The Mineral Resource estimate has been validated using visual validation tools, mean grade comparisons between the block model and declustered composite grade means, and swath plots comparing the input composite grades and the block model grades by Northing, Easting, and RL

No selective mining units are assumed in the estimate.

While at this stage the determination of potential environmental impacts, particularly for a green fields project, may not always be well advanced, the status of early consideration of these potential environmental impacts should be reported. Where these aspects have not been considered this should be reported with an explanation of the environmental assumptions made.	It is a requirement of Decree No.03-594/P-RM of 31 December 2003 of Malian law that an Environmental and Social Impact Study (Étude d’Impact Environmental et Social – EIES) must be undertaken to update the potential environmental and social impacts of the mine’s redevelopment. In November 2007 the EIES for the Syama Gold Mine was approved and an Environment Permit (07- 0054/MEA – SG) issued by the Ministry of Environment and Sanitation on the 22 November 2007.
			At Syama there are three key practices for disposal of wastes and
			residues namely, stacking of waste rock from open pit mining;
			storage of tailings from mineral processes; and “tall-stack
			dispersion” of sulphur dioxide from the roasting of gold bearing
			concentrate.
			The Environmental & Social Impact Study – “Société des Mines de
			Syama, Syama Gold Mine, Mali, dated 2007, found “a minimal
			potential for acid drainage from waste rock, as historical analysis
			indicates that the high carbonate content of the material will
			suppress any potential acid generation.” Progressive rehabilitation
			of waste rock landforms has begun and a management plan for
			waste rock dumping is the subject of ongoing development.
			The landform of tailings impoundments does not have a net acid
			generating potential. The largest volume is flotation tailings where
			the sulphide minerals have already been removed from the host
			rock. Its mineralogy includes 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 and dissipation of the sulphur dioxide is modelled daily to
			predict the need to pause the roasting process in order to meet the
