Dosquebradas Deposit

Dosquebradas is a near surface gold-copper deposit situated ~3km from the Company’s Miraflores deposit. Gold-copper mineralisation at Dosquebradas is associated with an early diorite porphyry and structurally controlled intrusive breccias. Previous drilling intersected mineralisation over an area of 400m x 300m, extending from surface to ~550m. Mineralisation remains open at depth, and to the north and east. The deposit has an Inferred Resource of  0.46Moz gold.
