Ambler Metals JV (50%)
•
50% interest in the Ambler Metals joint venture, which hosts two known base metals deposits
and numerous, early-stage volcanogenic massive sulphide (VMS) style exploration prospects
-
Arctic polymetallic deposit is one of the highest grade undeveloped base metals projects globally,
with a JORC Mineral Resource estimate of 37Mt averaging 3.06% Cu and 4.30% Zn(a)
- Bornite copper deposit is a large, carbonate hosted copper deposit, open at depth and laterally,
with open pit and underground potential
- Focused on consolidating geological knowledge and advancing engineering studies for Arctic,
while monitoring progress on approvals for the Ambler Mining District Industrial Access Project,
with a supplemental Environmental Impact Study expected in Q2 FY24
Roosevelt Project (100%)
Fully permitted, 10,000m drill program scheduled for the upcoming summer field season, targeting
potential copper and zinc mineralisation
