Orestone Mining Reports Drill Results from Captain Project

Orestone Mining Corp. has reported results from its January 2022 drilling program at the Captain gold-copper porphyry project, located near Fort St James in North Central British Columbia.

Drill hole C22-01 was designed to test a geophysical anomaly indicating a porphyry target at a depth of 500 metres. The hole intersected barren andesitic volcanic and volcanoclastic sequences down to 675 metres, followed by graphitic sediments to a total depth of 774 metres. A 75-metre-thick potassic-altered porphyry sill with disseminated sulphides was encountered at the volcanic-sediment contact but returned only background gold and copper values.

Orestone's interpretation suggests that a major northwest-trending fault likely truncated gold-copper mineralization to the west and uplifted the sequence of volcanics and sediments by approximately 450 metres. The company believes the graphitic sediments are responsible for the high conductivity anomaly detected.

Future exploration at Captain will focus on a large sericite-potassium feldspar alteration halo, measuring 2000 by 2000 metres, which has previously shown multiple gold-copper mineralized drill intercepts. Key underground targets, which remain largely untested, coincide with strong induced polarization (IP) chargeability highs and magnetic lows.

The 100 percent-owned Captain project covers 37 square kilometres and is situated north of Fort St James, near the Mt. Milligan copper-gold mine. The property features accessible terrain and an extensive road network suitable for year-round exploration.
