Karma Mine

The Karma mine was acquired in 2016, shortly before its first gold pour. Karma includes six identified gold deposits and is a shallow open pit with little blasting required and a low strip ratio, making it a low cost operation. In 2017, an optimization project was completed to lift the stacking capacity.

    Exploration Potential

    The 2018 exploration program amounted to $3 million, totaling approximately 23,600 meters of drilling, focused mainly on Yabonsgo and North Kao, resulting in: ­ 

    • The identification of a maiden Indicated resource at the Yabonsgo target totalling 2.9Mt at 1.28 g/t Au containing 119koz.­ 
    • The continuity of mineralization at the North Kao deposit was confirmed along an 800m strike length, with additional lenses identified to the south east.

    Other targets such as Rambo West, Mogombouli, Zanna, and Rounga were also studied to prepare for the 2019 drilling campaign. 

    An exploration program of up to $2 million totaling approximately 27,000 meters has been planned for 2019, with the aim of delineating near-mill oxide targets, mainly focused on testing the extension of the North Kao deposit and the along strike and northern plunge extension of the Yabonsgo deposit
