("Shanta Gold", "Shanta" or the "Company")

Singida JORC Reserve Estimate and Resource Update

Shanta Gold (AIM: SHG), the East Africa-focused gold producer, announces a JORC compliant Reserve and an updated and independently verified JORC compliant Mineral Resource Estimate ("MRE" or "Resource") on the Singida Gold Mining Project ("Singida" or "the Project") in Central Tanzania.

Highlights

  • JORC 2012 compliant gold reserve of 243koz at 3.00g/t;
  • Over 90% of contained gold within the reserve is between 0-120 metres from surface, highlighting the potential for reserve expansion at depth;
  • Updated life of mine plan to be released shortly;
  • Updated JORC compliant Mineral Resource at Singida totaling 11.8Mt, grading 2.38g/t and containing 904koz of gold, using a cut-off grade of 1.0g/t, including;
    o 17% increase in Measured and Indicated ("M&I") Mineral Resource, totaling 5.7Mt, grading 2.66g/t and containing 484koz;
  • MRE has been independently estimated and verified by a third-party Competent Person; and,
  • Financing discussions for the development of Singida are advanced and an announcement will follow, as appropriate.

Singida JORC Reserve

A JORC Reserve for the Singida Project has been declared, amounting to 243,000 oz at 3.00 g/t. This Reserve represents a 50% conversion of the Project's independently verified Measured and Indicated Resource. An updated mine plan for the Project will incorporate this Reserve and is expected to be released shortly.

Singida JORC compliant MRE

The Project's MRE has been re-estimated and independently verified by a third party Competent Person. This has resulted in a total MRE of 904,000 oz at 2.38 g/t, including a 17% increase in M&I Resources to 484,000 oz at 2.66g/t. This externally verified MRE supports Shanta's previously announced internal estimate and has formed the foundation of a JORC Reserve for the Project.

Eric Zurrin, Chief Executive Officer, commented:

"The Singida reserve allows the Company to move forwards towards construction and first production at Singida, confident in the fact that we have a number of high-grade open pits. Importantly, it is expected that this foundation will allow Singida to generate significant cashflow to, amongst other things, pay for regional exploration which will, over time, illuminate the Project's full potential.

The Singida reserve sits within a substantial resource and is located on a 4.9 km strike in a highly prospective greenstone belt. The reserve represents just 26% of the existing total contained resources and is nearly all within only 120 meters from surface, highlighting the potential for reserve expansion. The Project is fully permitted, and financing discussions are well advanced with an announcement expected soon."

Singida JORC Reserve

The Project's JORC 2012 Reserve at 26 May 2020 is 2.51 Mt, grading 3.00 g/t and containing 243,000 oz of gold at a cut-off grade of 1.0 g/t. This Reserve is being incorporated into an updated mine plan for the Project and represents an estimated 50% conversion of the Project's independently verified Measured and Indicated Resource. Of the total Reserve estimate, 91% of the contained gold is within 120 metres from surface.

orogenic intrusive phases associated with gold mineralisation in the

area. Subordinate diorite, porphyroblastic hornblende gabbro,

the understanding of the report, the Competent Person should

clearly explain why this is the case.

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-gradecaps 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

  • 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 Datamine Studio RM 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 Datamine Studio RM software for all block grade estimates

Classification

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

  • Density determinations have been carried out on the diamond cores. The results ranged from 2.82 g/cm³ to 3.15 g/cm³
  • 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. 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
