STUHINI TO ATTEND PDAC, OUTLINES EXPLORATION PLANS AND CURRENT TARGETS AT RED HILLS SILVER PROJECT

Stuhini Exploration Ltd. has provided an outline of its exploration plans for the 2025 season at the Red Hills property, located in White Pine county, Nevada. The company will attend the Prospectors and Developers Conference in Toronto, Ont., on March 2 to March 5.

The 2025 Red Hills exploration program will focus on building on the work conducted by previous operators of the property. This includes expanding on the detailed geological mapping and conducting an aeromagnetic survey. The company's goals for 2025 include identifying new drill targets and following up on untested targets on historical drilling, which intercepted significant carbonate replacement deposit mineralization (see Stuhini news releases dated Oct. 28 and Nov. 19, 2024). The project currently consists of three target areas, referred to as the Rattler, Tiger and Cobra zones.

Rattler zone

The Rattler zone multielement anomaly is situated within the west-dipping limestones, dolomites and silty carbonate rocks of the Pogonip group. This anomaly spans approximately 600 metres by 400 metres, and features a broad zone of strong multielement indicators, including elevated gold and silver concentrations in soil samples and mineralized structures.

Several historical workings are present within the Rattler anomaly, including one of the largest in the project. While these workings generally align with northwest-trending structures, replacement-style breccias and structures oriented more parallel to layering in a north-south to northeast direction have also been observed.

To date, the target area has been tested by four drill holes, three of which reached the target horizon with the best historic result being 17 metres of 129.7 grams per tonne silver, 0.15 g/t gold, 2.42 per cent lead and 0.92 per cent zinc, including 12 m of 179.2 g/t Ag, 0.20 g/t Au, 3.29 per cent Pb and 1.18 per cent Zn, which tested a shear zone. The table below summarizes the historic drilling results.

Tiger zone

The Tiger zone is immediately west of the Rattler zone. The target is defined by a multielement anomaly over 700 m of the strike length and exposures of a mineralized shear analogous but subparallel to the Rattler shear zone intercepted in hole 15RHR03. The highest-grade rock sample returned 1,535 g/t Ag. This target has never been drill tested.

Cobra zone

The Cobra zone is defined by a multielement soil anomaly and is situated along strike, south of the Rattler zone anomaly, within Pogonip group carbonate sediments. It spans a broad zone measuring approximately 950 m by 600 m. Several historical workings are present within the Cobra zone target area. Rock sample returned grades as high as 479 g/t Ag. The target area is also anomalous in copper mineralization, with malachite and azurite readily observed in spoil piles from old workings. Three drill holes between 120 and 130 m in length tested this target but failed to intercept the target horizon. Another drilling campaign is warranted on this target area to investigate other mineralized zones and possibly retest the previously drilled target but from a different location and different drill azimuth.

PDAC and Metals Investor Forum in Toronto

Stuhini also advises that it will be attending PDAC in Toronto, Ont., in early March. Dave O'Brien (chief executive officer), Ehsan Salmabadi (vice-president, exploration and development) and Charles Kamimura (corporate secretary) will be attending and be available to meet with investors and potential partners. It cordially invites you to visit with company representatives Sunday, March 2, through Wednesday, March 5, 2025, at booth No. IE 3018 at PDAC at the Metro Toronto Convention Centre.
