ArcWest Exploration Inc. announced that a 3D induced polarization survey has commenced at its 100% owned Teeta Creek Project, northern Vancouver Island, British Columbia. Dias Geophysical has been engaged to complete an IP survey over an untested zone of stockwork porphyry copper- molybdenum-gold-silver ("Cu-Mo-Au-Ag") mineralization delineated in 2022. The 2023 program, using Dias Geophysical's distributed array deep IP ("DCIP") survey system, should provide the first modern, high quality, and high-resolution 3-D resistivity and chargeability model of the subsurface below the stockwork zone.

The stockwork zone ("Gap zone"), situated at the lowest elevations on the property, is located within an approximately 400 m wide undrilled gap between the two best historical drill holes on the property. The Gap zone is hosted by intensely quartz-sericite-pyrite altered quartz-feldspar-biotite porphyritic intrusions. Potential therefore exists beneath the Gap zone for the discovery of a higher rade, Cu-Mo-Au mineralized potassic core.

The Gap zone was delineated during exceptionally low water levels in August, 2022, when ArcWest was able to examine significant, newly exposed creekbed outcrops of stockwork porphyry Cu-Mo-Au-Ag mineralization in Teeta Creek and tributaries. The Gap zone showings are the most prospective porphyry copper occurrences observed on the property to date. To the best of ArcWest's knowledge, the zone remains untested by drilling.

Highlights from mapping and sampling of the Gap zone include the following: Intense multiphase porphyry stockwork quartz-chalcopyrite-pyrite-molybdenite veining was discovered in normally submerged outcrops along Teeta Creek and tributaries on its north side. Rock samples from the stockwork zone returned assays ranging up to 0.53% Cu, 164 parts per million ("ppm") Mo, 0.353 grams per tonne ("g/t") Au and 3.6 g/t Ag. Stockwork mineralization is hosted in pervasively quartz-sericite-pyrite (QSP) altered feldspar- quartz-biotite porphyry intrusive rocks and is associated with zones of breccia.

Exposures of porphyry-style veining in QSP altered porphyry extend over an area of roughly 450 by 400 meters. The presence of QSP dominant alteration suggests potential for a higher grade, Cu- Mo-Au mineralized potassic core at depth. The stockwork zone is situated in a 365 meter-wide gap between historical drill holes from 1968-1975 drill campaigns, and well below elevations tested by Teck during its 2021 drill program.

ArcWest's 11,867 hectare Teeta Creek Cu-Mo-Au-Ag project is situated in northern Vancouver Island, southwest of Port McNeil. The 6.5-6.2 Ma Teeta Creek porphyry Cu-Mo-Ag system is situated approximately 5 km southwest of Port Alice, and is part of the recently discovered northeast trending Late Neogene Brooks Magmatic Suite, which includes volcanic rocks of the Alert Bay suite and coeval and older granitoid intrusions of the Klaskish Plutonic Suite. The Klaskish Plutonic Suite is one of the youngest magmatic belts containing porphyry copper systems in North America (Nixon et al, 2020).

Stockwork veining on the property was initially sampled by ArcWest geologists in 2019 at low elevations near Teeta Creek, including numerous large (up to 1m across), pervasively quartz-sericite-pyrite altered porphyry boulders along a tributary on the north side of the main valley. This work was followed up in 2022 in late August when water levels in the creeks were at their lowest levels, resulting in the delineation of the Gap zone. Stockwork zones in the Gap zone contain multiple phases of cross-cutting quartz, pyrite, chalcopyrite and molybdenite veins, locally approaching vein densities of 50% by rock volume.

Remnant magnetite and biotite are locally present, suggesting an early phase of potassic alteration which is almost completely overprinted by QSP. To date, 39 rock samples (grab samples) have been collected from the zone, returning the following assays: Cu - 181-5310 ppm (average 1291), Mo - 1.3-164 ppm (average 60); Au - 0.001-0.353 g/t (average 0.022); Ag - 0.16-3.61 ppm (average 1.1). Examples of mineralized porphyry stockwork and maps showing the distribution of the zones are available to view on ArcWest's. The altered and mineralized porphyry exposures documented in 2022, together with higher grade historical drill intercepts in drill holes 68-3 (0.36% Cu over 36.5 meters; 42.7-79.2m), 68-4 (0.34% Cu over 10.6m; 105.8-116.4m), and 75-1 (0.35% Cu over 67.1m; 103.6-170.7m; Noel, 1979) define an approximately 400 meter radius zone of consistently elevated Cu-Mo mineralization associated with quartz-sulfide stockwork and QSP dominant alteration; the zone is open to depth and to the southeast and was not tested by Teck's 2021 drill program.

Follow-up mapping in 2023 documented QSP-altered porphyry dykes and hydrothermal breccia over an area of 3.6 by 2.4 kilometers, which, although not fully delineated, provides a better sense of the size of the Neogene magmatic and alteration system at Teeta Creek.
