ArcWest Exploration Inc. announced that partner funded exploration drilling has intersected porphyry-style copper-gold-molybdenum ("Cu-Au-Mo") mineralization on its Oxide Peak project, situated in British Columbia's Toodoggone District, northern B.C. The project is being advanced by partner TDG Gold as part of an Earn-In Agreement. The Toodoggone region hosts extensive Early Jurassic porphyry Cu-Au and epithermal gold-silver (Au-Ag) mineralization including several past producing Au-Ag mines (Baker, Lawyers, Shasta) and the Kemess Au-Cu porphyry deposits (Centerra Gold). The southern half of the Oxide Peak project adjoins Benchmark Metals, which recently completed a Preliminary Economic Assessment of the Lawyers gold-silver deposit.

Historical production in the district exceeds 3.2 million ounces of gold and 360,000 tones of copper. Partner funded exploration at Oxide Peak in 2022 included 1021.5 meters of drilling from two drill holes collared at -45 and -60 inclination from the same drill site, located 500 meters southwest of and 240 meters elevation above outcropping chalcopyrite mineralization in Oxide Creek. Drilling intersected broad intervals of intensely quartz-sericite-pyrite (QSP) altered volcanic rocks cut by multistage quartz, sulfide and gypsum veins and stockworks.

Core sampling returning assay values up to 0.33 grams per tonne (g/t) Au and 0.23% Cu over 13 meters. The more steeply inclined drill hole OP22-002 begins to transition to K-feldspar-magnetite-chlorite (possible relict potassic) alteration at around 414-432 meters downhole depth. This suggests potential for increasing Cu-Au-Mo grades with depth, as the system transitions from QSP to potassic alteration.

Previous exploration at Oxide Peak in 2020 outlined a 1.5 by 0.6 kilometer chargeability high partly co- extensive with a multi-element (gold, copper, molybdenum, lead, zinc, silver, arsenic, bismuth, tellurium) soil anomaly within an extensive zone of quartz-sericite-pyrite (QSP) and advanced argillic alteration surrounded by sericite-chlorite and propylitic alteration. Gold-arsenic-tellurium is anomalous at higher elevations, with copper-molybdenum generally lower, reflecting a vertical transition from epithermal to porphyry environments. At lower elevations along the northern periphery of the soil anomaly, copper values over 0.1% occur in multiple grab samples (outcrops) over 200 meters in Oxide Creek.

Chalcopyrite mineralization is associated with multistage quartz-sulfide veining and relict K-feldspar- biotite-magnetite alteration hosted in variably brecciated, porphyritic monzodioritic intrusions. The initial drill test consisted of two drill holes from the same drill site, located 500 meters southwest of the Oxide Creek zone of porphyry-style copper mineralization. Outcropping porphyry Cu mineralization in Oxide Creek remains untested by drilling.

The 2022 Oxide Peak drill program intersected a sequence of highly altered volcanic rocks, cut by multiple plagioclase-biotite(-quartz) porphyry postmineral dykes. The volcanics are described as mainly rhyolite at shallow depths (including flow-banded rhyolite) and "undifferentiated" volcanics at deeper levels, with small intervals of dacite and ash tuff. In some cases, texturally destructive alteration has made it difficult to characterize the lithology.

Alteration of the volcanic rocks consists of variable silicification and sericite alteration at shallow depths to intense QSP alteration at depth. Intense QSP alteration is dominant in the volcanics from 283 meters to the end of the hole in OP22-001 and between 224 and 423 meters in OP22-022, and includes the intervals containing the strongest Cu-Au-Mo mineralization. The most strongly altered and mineralized zones contain multistage quartz, quartz-sulfide, and sulfide veining, with broad zones of intense gypsum stockwork logged below 434 meters in OP22-001, and below 320 meters in OP22-002.

Strong K- feldspar, chlorite (possibly after biotite) and magnetite alteration was logged in OP22-002 below 414 meters downhole, variably overprinted by QSP alteration. The style of alteration and veining, and association with Cu-Au-Mo mineralization at Oxide Peak is consistent with porphyry copper systems found elsewhere in the Toodoggone district. The dominance of QSP alteration associated with Cu-Au-Mo in these drill holes demonstrates that the potassic core was not tested by the 2022 drill program, and further drill testing along strike and at depth is required to adequately evaluate the system.

Further, it is not clear that the causative intrusion generating the porphyry system was intersected, since the porphyry intrusions logged all appear to be post-mineral. At approximately 500 m northeast of and 240 m below the 2022 drilling, an outcropping zone of chalcopyrite mineralized, chlorite-epidote-pyrite/QSP altered monzodiorite hosted hydrothermal- magmatic breccias with relict potassic alteration remains untested by drilling.
