Asset overview and operations

• Homase Mine is a fully operating, shallow open pit, heap leach gold mine with a JORC 2012 compliant resource of 602,000 oz, producing approximately 10 kilos of gold per month from a single shift, with plans to increase output to 450–550 oz per month by adding a second dry plant.
