Grumesa is the territory of alluvial deposits located right at the bank of the Ofin river. It is a world-call asset that BrightRock Gold acquired in 2013. With high-content reserves and low capital intensity, Grumesa is the main driver for the company’s growth in the medium term and an important source of income for investors.
The deposit is mined using hydraulic excavators ranging in size between 120 t and 200 t, with a backhoe configuration. Depending on the swell, flitches averaging between 2 x 2.5 m are used.
Ore and waste was excavated and loaded within the marked boundaries, thereby ensuring maximum ore recovery with minimum contamination.
