The Yaramoko permit covers approximately 196km2 in the Province of Balé in southwestern Burkina Faso. The property is located approximately 200 kilometres southwest from the capital city of Ouagadougou.
The underground mine is to be accessed by a dual ramp system, via a single portal at the bottom of a 23m deep box cut. LHOS (including up hole retreat in certain areas) is planned as the main mining method, with a limited application of cut and fill for the crown pillar mining. The mine layout is based on 17m sub-levels. Standard longhole stopes two sub-levels in height (34m) and 25m in strike length, are utilised to mine the narrow-vein ore body. By December 2018 AUMS will have delivered 17,100m of jumbo development, 120,000m of specialised narrow-vein 64mm longhole drilling, and 460,000t of ore. It is envisaged that personnel on site will be increased to over 220 by the end of this period.
