Shanta Gold Announces New Five-Year Production Plan

 

Shanta Gold (AIM: SHG), the East Africa-focused gold producer, developer and explorer, is pleased to announce a new five-year plan (the "Plan") for its gold assets in Tanzania, including New Luika Gold Mine ("NLGM") and Singida Gold Project ("Singida").

 

Highlights

 

Reserve and resource growth and mine life extension

·    Group-wide gold reserves as at 30 June 2021 of 666,000 ounces ("oz") grading 2.99 g/t (JORC compliant);

·    Gold reserves at NLGM of 423,000 oz grading 2.99 g/t, up from 382,000 oz grading 2.98 g/t as at 31 December 2020 (net of mining depletion);

·    Group-wide gold resources of 3,215,000 oz grading 3.62 g/t (JORC compliant in Tanzania and NI43-101 in Kenya);

New Luika (Tanzania): 1,129,000 oz grading 2.73 g/t;

Singida (Tanzania): 904,000 oz grading 2.38 g/t;

West Kenya Project (Kenya): 1,182,000 oz grading 12.6 g/t; and,

·    Reserve-based mine life extended to 2026 at NLGM and 2029 at Singida.

 

Transformational production increases from 2023 with significant upside potential

·    Group-wide gold production forecast from Tanzanian assets of approximately 499,000 oz for the five-year period from H2 2021 - H1 2026 (the "Plan Period");

·    Average annual gold production from Tanzanian assets of 116,000 oz from 2023-2025;

·    Significant upside through the potential conversion of 7.26 Mt grading 2.37 g/t for 552 koz resources at NLGM and 9.78 Mt grading 2.11 g/t for 664 koz resources at Singida currently sitting outside the Plan; and,

·    Shanta continues to invest in West Kenya to confirm the viability of a mine, with a construction decision expected before the end of 2023.

 

Rapidly reducing cost base between 2021 and 2025

·    Average consolidated Adjusted Operating Costs and All In Sustaining Costs ("AISC") of US$778 /oz and US$986 /oz respectively over the Plan Period.

 

Potential for further portfolio optimisation

·    Potential for further optimisation of the mining schedule, with the Company exploring the possible addition of a fourth ball mill, which would increase plant throughput beyond 2,450 tonnes per day and reduce cut-off grades.

Eric Zurrin, Chief Executive Officer, commented:

"It's been four years since we presented our last mine plan and we're proud of having delivered on and exceeded what we set out to do at that time. We feel even more excited about this Five-Year Plan and the transformational journey to becoming a 110,000+ oz gold producer from 2023.

 

Our revised group-wide gold reserves and resources at 666,000 oz and 3,215,000 respectively demonstrate the huge potential in the portfolio, and our extension of the reserve-based mine life to 2026 at New Luika and 2029 at Singida underpins our confidence in the long-term sustainability of both assets.

 

Whilst it's been a challenging 18 months for the entire world, our focus has remained on protecting our team and communities whilst continuing to grow our business. We have never been in such a strong position - with a healthy balance sheet, limited debt, a growing diversified portfolio and a maiden dividend launched this year. Our robust fundamentals will support our ambition to becoming a leading mid-tier gold producer in Africa."

Production Schedule - NLGM

 

The Plan provides for a combination of underground mining and open pit mining at NLGM. Key outcomes from NLGM's updated mining schedule include the following for the Plan Period:

 

·    Gold production of 367,773 oz from NLGM;

·    Average annual production of 73,600 oz, with the potential to extend mine life beyond 2026 through conversion of significant known resources currently sitting outside the Plan;

·    4.4 Mt milled, with forecasted throughput reaching 2,450 tonnes per day ("tpd") from late 2021 onwards, following the ramp up of the third mill commissioned in early 2021;

·    Mill feed continues at full capacity beyond 2026, with tonnes from tailings recovery available to supplement mined ore beyond the final year of the Plan if necessary;

·    Average anticipated recoveries of 89.1%;

·    Underground reserves to contribute 2.8 Mt of mill feed at an average grade of 3.46 g/t, for 311,601 oz contained;

·    Open pit reserves will support underground mining activities by contributing 1.4 Mt of mill feed at an average grade of 2.06 g/t, for 94,613 oz; and,

·    On-going exploration is expected to further enhance and extend the Plan in the future.

 

The strategy for NLGM is to maximise value and mine life through the inclusion of additional resources and reserves within and around the Company's mining licenses. All reserves incorporated in the Plan are within existing mining license areas.

 

Throughout the Plan Period, NLGM will blend underground mining of high-grade ores and surface mining of lower grade ores. The Plan provides for total mining extraction of 4.23 Mt for 406,214 oz contained, with 311,601 oz (77%) from underground mining and 94,613 oz (23%) from open pit mining. The balance of process feed ore will draw from stockpiles, gravels and mineralized waste, totalling 4,400 oz contained.

 

At this stage the maiden resource declared at open-pit deposit Porcupine South of 64,000 oz grading 2.08 g/t, near NLGM, is not included in the Plan and presents a clear opportunity for future mine life extension upon issuance of a mining license.

 

Under the Plan, the process plant maintains full capacity utilisation throughout the Plan Period. It is expected that additional resources from the existing portfolio of opportunities within the Company's mining licenses and surrounding exploration licenses will provide further mine life and optionality for NLGM.

Exploration and Future Potential

 

·    Resources presently sitting outside of the Plan amount to 7.26 Mt at 2.37 g/t for 552 koz at NLGM, and 9.8 Mt at 2.11 g/t for 664 koz at Singida;

·    These resources, which can potentially benefit from further exploration, have been prioritised for further evaluation. At NLGM these have the advantage that they all sit within proximity to the processing plant. Similarly at Singida, these all sit within proximity to the planned location of the processing plant;

·    A new mining license is being sought for the area occupied by Porcupine South, at which the Company recently declared a maiden resource of 64,000 oz. Should this license be granted, the Company expects to be able to incorporate an additional 295 kt of ore into the 2026 mining schedule at 2.16 g/t, for 20.4koz contained, prior to carrying out any further exploration works at the site. This would add an additional 18,200 oz to Mill production from mining activities in 2026;

·    NLGM's underground deposits are open at depth and carry significant inferred resources which the Company plans to explore further;

·    Shanta previously released its Revised Mine Plan ("RMP") in March 2017. In comparison, the Plan has increased average annual production (on a like-for-like five-year projection) by 21% and reserves by 29% from two mines; and,

·    Since March 2017, ounces contained within Shanta's global resources have increased by 168%.

Singida - Production Schedule

 

Project Economics for Singida were announced on 7th October 2020. The construction schedule for the project remains on track and first gold pour is anticipated towards the end of 2022. Highlights from the Project Economics announced previously include the following, which have been incorporated in the Plan:

 

·    Average annual gold production of 32,000 oz for an initial seven-year mine life through to at least 2029;

·              Total capital investment of US$26 m over a 24-month construction period, excluding pre-stripping, with first pour scheduled for late 2022;

·    Investment funded from internally generated cash flows;

·              All gold resources sit within existing mining licences;

·              91% of contained ounces in the Plan are within 120 metres of surface; and,

·    Significant further upside potential from substantial resources (9.8 Mt grading 2.11 g/t for 664,000 oz) currently sitting outside the reserve-based Plan.

Glossary

Glossary of Technical Terms

 

"Au"

chemical symbol for gold

"cut off grade" (COG)

the lowest grade value that is included in a resource statement.  It must comply with JORC requirement 19: "reasonable prospects for eventual economic extraction" the lowest grade, or quality, of mineralised material that qualifies as economically mineable and available in a given deposit.  It may be defined on the basis of economic evaluation, or on physical or chemical attributes that define an acceptable product specification  

"g/t"

grammes per tonne, equivalent to parts per million

"Inferred Resource"

that part of a Mineral Resource for which tonnage, grade and mineral content can be estimated with a low level of confidence.  It is inferred from geological evidence and assumed but not verified geological and/or grade continuity.  It is based on information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes which may be limited or of uncertain quality and reliability

"Indicated Resource"

that part of a Mineral Resource for which tonnage, densities, shape, physical characteristics, grade and mineral content can be estimated with a reasonable level of confidence.  It is based on exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes.  The locations are too widely or inappropriately spaced to confirm geological and/or grade continuity but are spaced closely enough for continuity to be assumed

"JORC"

The Australasian Joint Ore Reserves Committee Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves 2012 (the "JORC Code" or "the Code").  The Code sets out minimum standards, recommendations and guidelines for Public Reporting in Australasia of Exploration Results, Mineral Resources and Ore Reserves

"koz"

thousand troy ounces of gold

"Measured Resource"

that part of a Mineral Resource for which tonnage, densities, shape, physical characteristics, grade and mineral content can be estimated with a high level of confidence.  It is based on detailed and reliable exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes.  The locations are spaced closely enough to confirm geological and grade continuity

"Mineral Resource"

a concentration or occurrence of material of intrinsic economic interest in or on the Earth's crust in such form, quality and quantity that there are reasonable prospects for eventual economic extraction.  The location, quantity, grade, geological characteristics and continuity of a Mineral Resource are known, estimated or interpreted from specific geological evidence and knowledge. Mineral Resources are sub-divided, in order of increasing geological confidence, into Inferred, Indicated and Measured categories when reporting under JORC

"Mt"

million tonnes

"oz"

troy ounce (= 31.103477 grammes)

"Reserve"

the economically mineable part of a Measured and/or Indicated Mineral Resource

"t"

tonne (= 1 million grammes)

APPENDIX 1: SAMPLING TECHNIQUES AND DATA

 

 

 

Sampling techniques

·     Nature and quality of sampling (eg 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 (eg '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 (eg submarine nodules) may warrant disclosure of detailed information.

 

·     Diamond drilling 1m samples

·     Reverse circulation (RC) drilling was used to obtain 1 m samples from which 3 kg of material was sent for analysis

·     Drilling sampled on a maximum of 1 m downhole

·     Samples were not composited

·     Samples were submitted to the SGS Laboratory in Mwanza for analysis

·     At least 3kg sample pulverized and a 50g charge fire assayed with AAS or aqua regia finish for gold

Drilling techniques

·     Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg 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; NQ core size

·     RC Drilling

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.

·     Core sample recoveries routinely measured and recorded in spreadsheet database

·     Samples split half core perpendicular to strike of mineralized zones

·     RC samples recovered from on-site cyclone

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.

·     Logging of geology, alteration and geotechnical aspects recorded in drill logs for diamond core drilling

·     Logging is qualitative; All drill core is photographed

·     Entire intervals that were drilled and/or trenched were logged

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.

·     Half core taken; Sawn

·     RC samples riffled and sub-sample; Submitted for analysis

·     For trench samples, the entire sample for the respective interval aggregated, not riffled or split

·     Aggregated half core; Entire 3kg sample pulverized at laboratory prior to fire assay in order to minimize bias

·     Drilling and channels planned orthogonal to the strike of structures/lithologies in order to maximize representivity

·     Field duplicates sampled at appropriate intervals

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 (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established.

·     Fire assay is appropriate for the nature of gold mineralization being assayed

·     No geophysical tools used to generate exploration results

·     Registered reference material inserted at the interval of 20 samples

·     Levels of accuracy and precision (detection limit) for gold is 0.01 ppm which is suitable for the level of assays reported

·     Drillholes and trenches surveyed in UTM Coordinates System Arc 1960

·     Topographical surveys were done using Aerial Lidar Survey

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.

·     Drillhole spacing was generally at 50m along strike of the targets with a vertical spacing of approximately 40 to 50m

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.

·     Drilling and trenching planned perpendicular to the interpreted strike of lithological units and geological structures

Sample security

·     The measures taken to ensure sample security.

·     Samples secured by senior personnel on site and transported directly by company vehicle to the laboratories (Quality Labs in NLGM and SGS in Mwanza)

Audits or reviews

·     The results of any audits or reviews of sampling techniques and data.

·     Internal reviews are regularly completed but no external audits were carried out for the currently reported results

 

APPENDIX 2: REPORTING OF EXPLORATION RESULTS

 

 

 

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.

·     ML 408/2010 valid until 20 Sep 2030

·     ML 518/2014 valid until 30 Jan 2024

·     ML 519/2014 valid until 30 Jan 2024

·     ML 456/2012 valid until 19 Jan 2022

·     ML 455/2012 valid until 19 Jan 2022

·     ML 457/2012 valid until 19 Jan 2022

Exploration done by other parties

·     Acknowledgment and appraisal of exploration by other parties.

·     Historical colonial exploration and mining works

Geology

·     Deposit type, geological setting and style of mineralisation.

·     Underlain by a complex association of high grade metamorphic- and intrusive lithologies, commonly intruded by dykes of variable composition. Modally, granodioritic and granitic lithologies are most commonly encountered.

·     These granodiorites and granites have been interpreted as late-orogenic intrusive phases associated with gold mineralisation in the area. Subordinate diorite, porphyroblastic hornblende gabbro, quartzo-feldspathic felsite and migmatite are also regularly observed. 

·     Dyke intrusives include dolerite, pegmatite and common aplite and alaskite, seemingly randomly crosscutting major lithologies, and therefore regarded as younger than the country rock. 

Drill hole Information

·     A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes:

easting and northing of the drill hole collar

elevation or RL (Reduced Level - elevation above sea level in metres) of the drill hole collar

dip and azimuth of the hole

down hole length and interception depth

hole length.

·     If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case.

·     Relevant tables included summarizing drill holes and trenches locations, RL, azimuth, length/depth, and significant intersection intervals

Data aggregation methods

·     In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg 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 from drilling and trench sampling have been weighted by interval

·     High-grade caps have been applied

·     Lower cut-off grade of 0.5 g/t Au has generally been applied to significant intersections

·     Aggregate drilling and trenching intervals do not incorporate longer lengths of low-grade results

·     No metal equivalent reported

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 (eg 'down hole length, true width not known').

·     Drill holes and trenches have been drilled/excavated as perpendicular as possible to the general strike of the mineralized zones and structures so that the intersected lengths are close to true widths

Diagrams

·     Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views.

·     Maps and sections are being generated

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.

·     All significant drilling and trench results have been reported

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.

·     Metallurgical studies of the ore from potential five pits were conducted and completed by SGS in South Africa in 2009. The ore minerology variability is insignificant but relatively coarse gold grain was observed

·     The relatively coarse nature of much of the gold provides reason for an upfront gravity circuit to recover coarse gold prior to cyanidation. An overall gold recovery of 90% can be achieved through gold dissolution by direct cyanidation and the gravity concentrator.

Further work

·     The nature and scale of planned further work (eg 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.

·     Drilling to be continued to test along strike and the down-dip continuity of the delineated mineralization

 

APPENDIX 3: ESTIMATION AND REPORTING OF MINERAL RESOURCES

 

 

 

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.

·     The data capturing Access database is linked to a superseding Access database on the geological server

·     Queries allow specially selected information from the captured data and create core data sheets which include Collar, Survey, Lithology and Assay logs. These Logs are finally displayed in the mining software

·     An independent validation process is run for each log sheet in Micromine by Shanta. Should there be any queries, a report file is created and exported to excel. The report will be mailed to the personnel responsible for data capturing to correct on the original data

·     Once confirmation is given of the updates, all databases are refreshed and the validation process in Micromine repeated with the use of form sets

·     Once all data validates, a number for the tear of validation is indicated in the collar file of the superseding database

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.

·     Dr Corné Koegelenberg, assisted by Mr Jonathan Gloyn-Jones, visited the property from the 14 - 20th of February 2020 to conduct a drill core investigation of macrostructural and gold mineralization features. Mr Ken Lomberg joined the site visit from the 19 - 20th of February 2020

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.

·     Diamond drilling was done perpendicular to the strike of the ore body at a dip designed to give a true intersection width of the mineralized body at a spacing less than 42m

·     The downhole survey was done at every 15m

·     Core meter marking, geological logging, structural interpretation, core sampling, Data validation and QAQC analysis was done by competent and experienced geologists

·     Only samples submitted to the accredited laboratory (SGS Mwanza) are used in the estimate

·     The limits of the structural features hosting the mineralized zone was interpreted by overlaying the assays against geological logging section by section using section strings

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.

·     Drill hole spacing is generally between 25 to 42m along with a vertical spacing of approximately 20 to 38m in the upper to mid-level portions of the mineralized zones. This drilling spacing combined with the surface exposures and trench sampling, along with the geophysical data, permits the assumption that both the mineralized structures are continuous and persistent, and the mineralization within the structures has the continuity necessary to consider these deposits as Mineral Resources

Estimation and modelling techniques

·     The nature and appropriateness of the estimation technique(s) applied and key assumptions, including treatment of extreme grade values, domaining, interpolation parameters and maximum distance of extrapolation from data points. If a computer assisted estimation method was chosen include a description of computer software and parameters used.

·     The availability of check estimates, previous estimates and/or mine production records and whether the Mineral Resource estimate takes appropriate account of such data.

·     The assumptions made regarding recovery of by-products.

·     Estimation of deleterious elements or other non-grade variables of economic significance (eg sulphur for acid mine drainage characterisation).

·     In the case of block model interpolation, the block size in relation to the average sample spacing and the search employed.

·     Any assumptions behind modelling of selective mining units.

·     Any assumptions about correlation between variables.

·     Description of how the geological interpretation was used to control the resource estimates.

·     Discussion of basis for using or not using grade cutting or capping.

·     The process of validation, the checking process used, the comparison of model data to drill hole data, and use of reconciliation data if available.

·     Compositing data into regular composite intervals was performed to moderate the presence of extreme short sample interval grade values in the data, by combining them with adjacent data to form the composite

·     A combination of several methods was used to decide what constitutes an appropriate capping value. The spatial position of outlier values, as well as coefficient of variation plots, lognormal probability plots and decile analysis, were used in the determination of capping values

·     Scatter plots of the gold grade composites versus location were generated, to assess any potential non-stationarity in the data

·     Block models were created to represent the mineralized body contained within the wireframe solids for each target. Cell sizes were chosen based on the average drillhole spacing

·     Geostatistics was performed using Micromine software to determine the estimation parameters

·     The mineralized targets were modelled for gold grade using Ordinary Kriging, with the shell of the wireframe solid as a hard boundary. Only data within the solid was used in the estimate

·     The Estimation process used Micromine software for all block grade estimates

Moisture

·     Whether the tonnages are estimated on a dry basis or with natural moisture, and the method of determination of the moisture content.

·     Tonnages are reported on a dry basis

Cut-off parameters

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

·     A simple financial assessment was undertaken to ascertain whether they fulfil the criteria of "reasonable prospects for eventual economic extraction" using current operating costs

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.

·     The mineral resource was deemed amenable to extraction by open pit mining method and were declared at a cut-off of 1.0g/t

Metallurgical factors or assumptions

·     The basis for assumptions or predictions regarding metallurgical amenability. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider potential metallurgical methods, but the assumptions regarding metallurgical treatment processes and parameters made when reporting Mineral Resources may not always be rigorous. Where this is the case, this should be reported with an explanation of the basis of the metallurgical assumptions made.

·     Shanta commissioned the first of a series of gold deportment and metallurgical studies on mineralized material from potential pits in 2009. Reverse circulation drill chips from five mineralised targets were submitted for gold deportment studies in order to understand the mode of gold occurrence, and to ascertain possible cost effective and practical process routes.

·     Further metallurgical studies commissioned on mineralized material from the Gold Tree (Tree Top and Tree Bottom) deposit in 2011 support initial gold deportment findings. A report from Mintek summarized that the ore contains coarse gold which should be recovered prior to the leaching process with an overall gold recovery 90% - Mintek External Report No: 5887 of February 2011).

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 greenfields 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.

·     Shanta Mining Company Limited is fully permitted mining operation under Tanzanian law with the prerequisite Environmental Impact Assessments (EIA) issued in 2019.

 

Bulk density

·     Whether assumed or determined. If assumed, the basis for the assumptions. If determined, the method used, whether wet or dry, the frequency of the measurements, the nature, size and representativeness of the samples.

·     The bulk density for bulk material must have been measured by methods that adequately account for void spaces (vugs, porosity, etc), moisture and differences between rock and alteration zones within the deposit.

·     Discuss assumptions for bulk density estimates used in the evaluation process of the different materials.

·     Density determinations have been carried out on the diamond cores.

Classification

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

·     Whether appropriate account has been taken of all relevant factors (ie relative confidence in tonnage/grade estimations, reliability of input data, confidence in continuity of geology and metal values, quality, quantity and distribution of the data).

·     Whether the result appropriately reflects the Competent Person's view of the deposit.

·     The resources have been classified as Measured, Indicated and Inferred based primarily on sample spacing as determined by drilling density and proximity to informing data as well as the grade distribution of the supporting data including geology.  For the resource classification, a solid shape was constructed around the parts of the mineralised body where most estimates were informed by data not more than 30m from the estimated block, are estimated within the primary search volume, and where the estimates have been interpolated rather than extrapolated. All blocks located within these areas were classified as Measured and Indicated resources. All blocks located outside of these areas, around the periphery of the drilling were classified as Inferred resources

Audits or reviews

·     The results of any audits or reviews of Mineral Resource estimates.

·     Only internal audit completed

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.

·     Refer Estimation and modelling techniques comments above
