The 97 square-kilometre Onjo copper-gold porphyry property is located 70 kilometres north of Fort St James and 10 kilometres west of Centerra’s Mount Milligan mine (Figure 1) within the Quesnellia arc, host to several significant alkalic copper-gold porphyry deposits. The Onjo property occurs on the same magnetic trend that hosts the Mount Milligan mine, the Chuchi deposit and Northwest Copper Corp.’s Kwanika deposit.

On June 3, 2021, Orogen announced the acquisition of the Onjo copper-gold porphyry property. The Onjo property was identified through Orogen’s generative exploration programs and was acquired through staking.

On February 3, 2022, Orogen announced the completion of a purchase and sale agreement to sell 100% of the Onjo project to Pacific Ridge Exploration Ltd. (“Pacific Ridge”). Upon closing, Orogen will receive $50,000 cash, and 750,000 common shares of Pacific Ridge, and a 2.0% net smelter return royalty, of which 0.5% can be purchased for US$1.5 million.
