The Yaramoko Mine is situated in the Houndé greenstone belt region in the Province of Balé in southwestern Burkina Faso. The property is located approximately 200 kilometers southwest from the capital city of Ouagadougou (Latitude: 11° 45’ 25” N, Longitude: 3° 16’ 58” W).

Our operations add value to Burkina Faso’s formal economy by providing contracts and stable jobs for local people and by helping to expand the revenue base of our host government through income taxation, national social security system contributions and the royalties we pay every time we ship gold.

  • Notes:
    • Mineral Reserves and Mineral Resources are as defined by the 2014 CIM Definition Standards for Mineral Resources and Mineral Reserves
    • Mineral Resources are exclusive of Mineral Reserves
    • Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability
    • Factors that could materially affect the reported Mineral Resources or Mineral Reserves include; changes in metal price and exchange rate assumptions; changes in local interpretations of mineralization; changes to assumed metallurgical recoveries, mining dilution and recovery; and assumptions as to the continued ability to access the site, retain mineral and surface rights titles, maintain environmental and other regulatory permits, and maintain the social license to operate
    • Mineral Resources and Reserves for the Yaramoko Mine are estimated and reported as of June 30, 2020
    • Mineral Reserves for Yaramoko are reported at a cut-off grade of 0.9 g/t Au for the 55 Zone open pit, 3.1 g/t Au for 55 Zone underground and 2.8 g/t Au for Bagassi South underground, based on an assumed gold price of US$1,500/oz, metallurgical recovery rates of 98.0%, surface mining costs of US$3.26/t, G&A costs of US$14.5/t, and processing cost of US$22.85/t, underground mining cost of US$95.5/t, G&A costs of US$15.2/t, and processing cost of US$22.5/t.  Underground mining recovery is estimated at 95% for stopes and 100% for sill drifts with a mining dilution of 10% for sill drifts, 0.7m and 0.9m dilution skin for 55 Zone and Bagassi South stopes respectively. Surface Mineral Reserves are reported in situ with modifying factors of 10% mining dilution and 85% mining recovery applied within an optimized pit shell. Yaramoko Mineral Resources are reported in situ at a gold grade cut-off grade of 0.5 g/t Au for the 55 Zone open pit and 2.7 g/t Au for underground, based on an assumed gold price of US$1,700/oz and the same costs, metallurgical recovery and constrained within an optimised pit shell. The Yaramoko Mine is subject to a 10% carried interest held by the government of Burkina Faso.
