Activity by Year

Year	Activity	Status	Operator	Project Name	Description
2018	Exploration	Exploration Project	Kennecott; Rio Tinto		Tubutulik Mining Company LLC leased the Oreo property to Kennecott/Rio Tinto, which conducted grassroots exploration over the potential porphyry copper?gold target.
2019	Exploration	Exploration Project	Tubutulik Mining Co.		Kennecott Exploration explored the Oreo Mountain copper-molybdenum porphyry prospect under option from Tubutulik Mining Company LLC. The prospect lies 37 miles east of Tok and was known principally as a copper-molybdenum soil anomaly until drill testing in 2019. Kennecott tested three main target areas with a total of six relatively shallow holes, the deepest being 613 ft. Copper ± molybdenum mineralization was intercepted in all six holes, with broad intercepts of low-grade copper mineralization in most holes. Several holes intercepted locally strong molybdenum mineralization associated with potassium-felspar alteration.
