WETAR COPPER PROJECT A GEOLOGICAL OUTLOOK

GEOLOGY OF WETAR COPPER DEPOSIT ~ 5 MILLIONS YEARS AGO

GEOLOGY OF WETAR COPPER DEPOSIT PRESENT TIME

• Favorable lithological setting for VMS and other hydrothermal systems • Presence of paleo-surface (exhalative, chert, and gossans) • Strong and continuous VMS and hydrothermal alteration

DEPOSIT GEOLOGY

Kali Kuningg Mine

After digging thin scree overburden, we’ll straight on business  Lerokis Mine

MINERALOGY

Primary MS
