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. For comparative purposes, data for the previous year has been included where possible. 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 for the Sukari Gold Mine Mineral Reserve report. Currently, all the Mineral Reserves are contained within the Sukari tenement. For comparative purposes, data for 2019 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 at 31 December 2020 were 5.0 million ounces of gold. The decrease from 2019 is attributable to mining depletion more than Mineral Reserve additions, Mineral Resource changes, changes in the open pit design and stope sterilisation. The gold price assumption of US$1,450 per ounce was used for estimating Mineral Reserves. Based on the expected throughput rates, the remaining Mineral Reserve life of Sukari open pit operation and stockpiles is approximately 12 years and approximately 4 years for the underground, as of 31 December 2020.

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 Multiple Indicator Kriging 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 approximately 25 x 50 metre spacing and Inferred resources exist in areas of broader spaced drilling.
  • The open-pit MRE at a 0.3 g/t Au cut-off grade extends over a strike length of 2.5 kilometres, a width of 500 m and from current surface to a depth of ~900 m.
  • The open-pit MRE used all available surface drilling, channel and chip samples as at 18 July 2019, and longer underground production holes were also included. The open-pit resource data set comprised 389,856 two-metre drill hole composites and surface rock chip samples.
  • H&SC has checked the drilling completed between July 2019 and December 2020 and considers that this data is unlikely to have a significant impact globally, although some local differences are expected.
  • The MRE was adjusted to the mining surface and underground mining voids as at the 31^st of December 2020.
• Sukari Underground
  • All underground Mineral Resources are estimated using Ordinary Kriging using Surpac software.
  • Measured Resources lie in areas where drilling is available at least 20 x 20 metre spacing and the interpreted mineralisation defined by underground mine development. Indicated resources occur in areas drilled at approximately 20 x 20 metre spacing and Inferred Resources exist in areas of broader spaced drilling of approximately 50 x 50 metre spacing.
  • The underground Mineral Resource estimate at a 1.0 g/t Au cut-off grade extends over a strike length of 2.5 kilometres, a width of ~500 m and from current surface to a depth of 1,200 m.
  • All available surface drilling, channel and underground samples were used as at 31st August 2020. The resource data set used directly in the Mineral Resource Estimate comprised a total of 68,202one metre down hole drilling composites and 53,970 one metre down hole channel sample composites.
  • The Mineral Resource Estimates were adjusted to the mining surface and underground mining voids as at end of December 2020.
• Doropo Project
  • The estimation method is Multiple Indicator Kriging (MIK) using GS3 software
  • Measured Resources occur in areas drilled at approximately 25 x 25 metre spacing and Indicated Resources occur in areas drilled at approximately 50 x 50 metre spacing. Inferred Resources exist in areas of broader spaced drilling.
  • The reported estimates are limited to blocks with a maximum depth of 250 metres below surface and within 80 metres of drill hole data
  • All available data was used as of 18 August 2019
  • 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.
• ABC Project
  • The estimation method is Multiple Indicator Kriging (MIK) using GS3 software
  • Indicated resources occur in areas drilled at approximately 50 x 50 metre spacing and Inferred resources exist in areas of broader spaced drilling
  • The reported estimates are limited to blocks with a maximum depth of 250 metres below surface and within 100 metres of drill hole data
  • All available ABC data was used as of 10 December 2018
  • 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 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.
• Batie West Project
  • 2014 Konkera Mineral Resource estimate was a geologically constrained estimate using 10m x 5m x 2.5m blocks with an associated block proportion coded into each block with a precision of +/-1%.
  • Semi-variograms were generated for each mineralisation domain ranging from 50-95m along strike and 45-70m down dip. Search ellipses ranged from 70m x 60m x 10m to 60m x 50m x 5m with a maximum of 24 composites and a maximum of 3 composites per hole for any single block estimate.
  • The classification methodology involved an unbiased allocation of block mode parameters into a quality of estimate (QLTY) measure for Measured, Indicated and Inferred. Nominally Measured Resources occur in areas drilled at approximately 25 x 25 metre spacing, Indicated Resources occur in areas drilled at approximately 50 x 50 metre spacing and Inferred Resources exist in areas of broader spaced drilling.
  • The Mineral Resource estimate is reported using a gold cut-off grade of 0.5 g/t
  • All available data was used as at 1^st February 2014.

Reserve Notes

• Open pit and stockpiles cut-off grade for reporting of 0.4g/t
• Open pit Mineral Reserve estimate includes 7.5Mt at 0.4g/t for 0.1Moz gold, using a 0.2g/t cut-off, for the dump leach
• Underground cut-off grade for reporting of 0.4g/t gold for development with stopes defined within a 1.6g/t gold cut-off

Mineral Resource Estimates contained in this document are based on available data as at:

• Sukari Gold Mine - 18 July 2019
• Doropo Project - 18 August 2019
• ABC Project - 10 December 2018
• Batie West Project - 26 March 2014

H&S Consultants PTY Ltd completed the open pit MIK MRE for Sukari as at the end of June 2019. The estimates are reported below the end of June 2019 mined surface and within a pit shell generated by Cube Consulting using a nominal gold price of US$1900/oz. A cut-off grade of 0.3 g/t gold is used for reporting the open pit MRE because this is the nominal economic open-pit cut-off grade used at the Sukari mine.

Cube Consulting Pty Ltd (Cube) completed the estimation of the Sukari Gold Mines Underground Mineral Resource as at the end of June 2019. All UG mineral resources defined below the USD $1,900/oz shell are estimated using the economic underground cut-off grade of 2.0 g/t and are combined with the open pit MRE to provide a global MRE for Sukari. The global mineral resource estimate includes the underground resource estimate.

Varying cut-off grades have been used, and clearly marked, for calculating the mineral resource estimates at different Group properties, depending on the stage of project, maturity and ore type.
