The Mineral Resource data presented in the tables included in this document comprise a summary extract for the Mineral Resource reports for all the Group’s properties. Numbers have been rounded and therefore there may be small differences in the totals. Varying cut-off grades have been clearly stated.

The Mineral Resources were estimated using a gold price assumption of US$2,000/oz at Sukari Gold Mine in Egypt and to a maximum vertical depth of 250 metres at both the Doropo Project and ABC Projects in Côte d’Ivoire.

The significant figures used in the table are intended to reflect the level of accuracy of the different resource classifications reported; figures in the table may not add correctly due to rounding.

Sukari Gold Mine only

The Mineral Reserve data presented in the tables included in this document comprise a summary extract from the Sukari Mineral Reserve report. Currently, all the Mineral Reserves are contained within the Sukari Concession area. For comparative purposes, data for 2021 has been included. Numbers have been rounded and therefore there may be small differences in the totals.

Included in the Mineral Resources, the Mineral Reserves as of 30 June 2022 were 6.0Moz of gold. The increase, net of twelve months depletion, from 2021 is attributable to significant Mineral Resource to Mineral Reserve drill conversion within the open pit and underground. The gold price assumption used for estimating Mineral Reserves is unchanged at US$1,450/oz. Based on the planned throughput and mining rates, the remaining Mineral Reserve life of Sukari open pit operation and stockpiles is approximately 14 years and 10 years for the underground, as of 30 June 2022.

Mineral Resource Notes

All open-pit Mineral Resources are estimates of recoverable tonnes and grades using Multiple Indicator Kriging with block support correction produced in the GS3 software.

All underground Mineral Resources are estimated using Ordinary Kriging using Surpac software.

• Sukari Open Pit
  • All open pit Mineral Resources are estimates of recoverable tonnes and grades using MIK with block support correction produced in the GS3 software.
  • Measured Resources lie in areas where drilling is available at a nominal 25 x 25 metre spacing, Indicated Resources occur in areas drilled at ~25 x 50 metre spacing and Inferred resources exist in areas of broader spaced drilling.
  • The open pit Mineral Resource estimate at a 0.3 g/t Au cut-off grade extends over a strike length of ~2.5 kilometres, a width of ~500 metres and from current surface to a depth of ~900 metres.
  • The open pit Mineral Resource estimate used surface rock chip, diamond, reverse circulation and advanced grade control drilling, while open-pit grade control and underground face samples were excluded with the dataset being closed off as at 15 July 2022. The open-pit resource data set comprised 553,776 two-metre drill hole composites and surface rock chip samples.
  • The Mineral Resource estimates were adjusted to the mining surface and underground mining voids as at 30 June 2022, and includes some material that could be mined by underground methods.
• Sukari Underground
  • All underground Mineral Resources are estimated using OK and Vulcan software.
  • Measured Resources lie in areas where drilling is available on at least 20 x 20 metre spacing and the interpreted mineralisation defined by underground mine development. Indicated Resources occur in areas drilled at ~50 x 25 metre spacing and Inferred Resources exist in areas of broader spaced drilling of ~100 x 50 metre spacing.
  • The underground Mineral Resource estimate at a 1.0 g/t Au cut-off grade is unconstrained and extends over a strike length of ~2.5 kilometres, a width of ~500 metres and from current surface to a depth of ~1,200 metres.
  • All available surface drilling, channel and underground samples were used as at 30 June 2022. The resource data set used directly in the Mineral Resource Estimate comprised a total of 125,547 one metre down hole drilling composites, 188,559 one metre down hole channel sample composites and 31,288 two and a half metre down hole drilling composites.
  • The Mineral Resource Estimates were adjusted to the mining surface and underground mining voids as at 30 June 2022.
• Sukari Stockpiles
  • Open Pit, Underground and Course Ore Stockpile material have been reported at a cut-off of 0.4g/t Au.
• Doropo Project
  • All available data was used as at 25 October 2022.
  • The gold grade estimation method is Localised Uniform Conditioning.
  • The rounding of tonnage and grade figures has resulted in some columns showing relatively minor discrepancies in sum totals.
  • All Mineral Resource Estimates have been determined and reported in accordance with NI 43-101 and the classification adopted by the CIM.
  • A cut-off grade of 0.5 g/t gold is used for reporting as it is believed that the majority of the reported resources can be mined at that grade.
  • The 2021 MRE was limited to blocks with a maximum depth of 250 metres below surface and within 80 metres of drill hole data.
  • Pit optimisations based on a US$2,000/oz gold price were used to constrain the 2022 Mineral Resource and were generated by Orelogy Mine Consultants, who are working on the PFS.
  • The Mineral Resource Estimate was prepared by Mr. Mike Millad of Cube Consulting Pty Ltd who is the Qualified Person for the estimate.
  • This Mineral Resources Estimate is not expected to be materially affected by environmental, permitting, legal title, taxation, socio-political, marketing or other relevant issues.
• ABC Project
  • Mineral resources which are not mineral reserves do not have demonstrated economic viability.
  • The ABC resource estimate comprises two (2) deposits – Kona South & Kona Central.
  • Drill spacing is a nominal 50 x 50 x 1 metre spacing.
  • Reverse Circulation (RC) and Diamond (DDH) drilling only has been used for the estimation.
  • An OK and LUC estimation using IK at Kona Central to define ore and waste boundaries.
  • The grade estimate has been classified as Inferred in accordance with the CIM 2014 guidelines.
  • The Mineral Resource has been reported at an economic cut-off grade of 0.5g/t, 250m below surface and within 100 metres of the nearest sample.
  • The Mineral Resources Estimate was prepared by Mr. Patrick Adams of Cube Consulting who represents the Qualified Person for the estimate.
  • The Mineral Resources Estimate is not expected to be materially affected by environmental, permitting, legal title, taxation, socio-political, marketing or other relevant issues.
• The Doropo and ABC resource data sets include RC and Diamond drill data with gold estimates based on 50-gram Fire Assay analysis completed at Bureau Veritas Mineral Laboratories, Abidjan.

Mineral Reserve Notes

• Open pit and stockpiles cut-off grade for reporting of 0.4g/t Au.
• Open pit Mineral Reserve estimate includes 1Mt at 0.4g/t Au for 0.1Moz gold, using a 0.2g/t Au cut-off grade, for dump leach material.
• Underground cut-off grade for reporting of 1.0g/t Au for development with stopes defined within a 2.2g/t Au cut-off.
