The property is underlain by the Ashanti gold belt, one of the world’s most significant Proterozoic gold belts discovered to date. The belt is the most prominent of the five Birimian Supergroup gold belts found in Ghana and is predominantly comprised of sedimentary and mafic volcanic rocks. The Brimian terranes in the southern part of the West African craton are several different volcano-sedimentary formations including metamorphosed volcanic, sedimentary and plutonic rocks and low-grade metavolcanics and metasediments. Two types of granite are present, one is more resistant to weathering than the other, with the less-resistant granite containing gold mineralization.

Mineralized shears are found close to the contact with harder metamorphosed and metasomatically altered geology forming the Upper Birimian volcanics. Two main ore types are present at AKHM hosted within quartz veins and sulphide ores. Subsurface investigation within the mineralized trend undertaken by Ashanti Goldfields revealed a wide zone of shear about 800m long, 14m wide between 255m and 70mRL elevation. Shear mineralized zone metasediments dip sub-vertical or steeply to the NW and strike NNE.

Comparable features of Birimian mesothermal gold mineralization between Obuasi and AKHM (Akrokeri-Homase) include quartz veins and mineralization in graphitic shear zones, along with visible gold occurring in fractures within a quartz veins. Most of the gold is contained between these graphite-ric ........

The Homase Mine, set within its AKHM project in Ghana, consists of five open pits, targeting the oxide resource to a vertical depth of 30 metres.

The company will be treating the oxides from the Homase Mine on the heap leach processing facility and retreating the tailings from the former Akrokeri Mine that closed in 1909, with results from an auger drilling showing three blocks of viable mineralized zones to a depth of three meters with an average grade of 2.27g/t and estimated tonnages of 91,000t. Metallurgical testwork indicated tailings are amenable to the cyanide heap leach process with an overall recovery of 73%. GoldStone expect to recover up to 5,000oz from these tailings over the life of mine.
