COPPER GOLD PROJECT

Central Java, Indonesia

  • SUNDA MAGMATIC ARC

  • Copper Gold Project

  • 3,928 ha

  • Porphyry and Epithermal 

  • ADVANCED 1 Moz Au-Cu PORPHYRY OPEN AT DEPTH.

  • POTENTIAL FOR NEAR TERM MINE DEVELOPMENT.

  • HIGH GRADE PERIPHERAL EPITHERMAL PROSPECTS ONLY SCOUT DRILLED.

COPPER GOLD PORPHYRY & EPITHERMAL PROJECT

  • Advanced 3,928hectare IUP (Exploration Mining Permit) for porphyry and epithermal gold and base metals.

  • Exploration includes 21,771m of drilling, mostly at the Randu Kuning porphyry deposit.  Porphyry deposit remains open at depth with potential for additional Au within adjacent epithermal veins.

  • 1.15 million oz gold equivalent JORC mineral resource comprising:

    • 996 thousand oz of gold (53% measured & indicated) and;

    • 190 million pounds of copper (43% measured & indicated).

  • Excellent metallurgy, gold recovery of 90-91% with simple Carbon In Leach flowsheet.

  • Potential intrusive corridor extension identified.

  • Scout drilling of epithermal veins returned grades up to 3m at 7.79 g/t Au, 9.0 g/t Ag, 0.29% Cu and 0.38% Zn from 70.0 metres including 1m of 15.90 g/t Au and 20.7 g/t Ag.

project location

  • The Wonogiri project is located approximately 30 kilometres to the south of the provincial city of Solo in central Java and is easily accessible by daily flights from the capital Jakarta and a short 1 hour drive by car on a sealed road.

  • The project lies within the Sunda-Banda arc and covers an area of 3,928 hectares.  The region host several world-class porphyry-copper gold and epithermal gold-silver deposits.

Significant intercepts

Deposit remains open at depth with drill hole IWG 02 returning 37 m at 1.77 g/t Au and 0.23% Cu from 458 m (including 1m at 6 g/t Au).

“The Randu Kuning Deposit remains open at depth. Previously deeper intersected
higher-grade zones may be amenable to selective underground mining after initial open pit mining.”        

RANDU KUNING PORPHYRY DEPOSIT - INTRUSIVE CORRIDOR EXTENSION

Future work will determine if deep extension of RK resource and drill test additional porphyry targets defined by reinterpretation of historical survey data.

Planned Exploration Activities

In-fill drill program planned for the Randu Kuning deposit to support feasibility study and test for potential deposit extensions at depth. Continued exploration drilling of adjacent epithermal Au prospects.
