Orogen acquires Onjo copper-gold property in British Columbia

Onjo is located approximately 10 km west of Centerra Gold Inc.’s Mount Milligan Mine and 10 km south of the Chuchi copper-gold deposit. The Onjo property was identified through Orogen’s generative exploration programs and recently acquired through staking.

Onjo property highlights:

• Onjo is located in the Quesnellia arc and on a magnetic trend hosting the Mount Milligan mine (proven and probable reserves of 959 million lbs copper and 2.4 million oz gold), and the Kwanika and Chuchi copper-gold deposits.
• Historical drilling intersected multiple small dykes of monzonite associated with anomalous copper mineralisation.
• Relogging of historical drilling by Orogen highlights an approximate 500 by 500 m zone with indicators of the top of an alkalic porphyry copper-gold system.

Laurence Pryer, Exploration Manager for Orogen, comments:

“The acquisition of the Onjo property is the result of using evolving exploration models to generate new exploration targets.

“Orogen’s technical team believes vectoring into copper-gold mineralisation from the tops of alkalic porphyry copper-gold systems represents a significant exploration opportunity in British Columbia as all major discoveries to date are eroded to the level of the mineralising intrusion.

“Major porphyry copper-gold systems, including Newcrest’s Cadia-Ridgeway mines in New South Wales, Australia, and Vale S.A.’s Onto copper-gold deposit in Indonesia, which were discovered where mineralising intrusions occur at depth, provide excellent analogues to generate porphyry targets such as the Onjo property.”
