GRIZZLY MOBILIZES DRILLING AND IP CREW TO THE SAPPHO CRITICAL MINERALS TARGET GREENWOOD, BRITISH COLUMBIA

A crew from Full Force Drilling Ltd., of Peachland, B.C., has arrived at Grizzly Discoveries Inc.'s Greenwood and has commenced drilling critical minerals skarn targets co-incident with a high-conductivity anomaly at the Sappho area. Grizzly intersected skarn along with porphyry-type alteration and anomalous Cu-Ag-Au-PGEs (copper, silver, gold and platinum group elements) in three of four 2010 core holes. Historical 2010 drilling by the company yielded up to 0.31 per cent Cu, 0.75 gram per tonne (g/t) Au, 0.34 g/t platinum (Pt), 0.39 g/t palladium (Pd) and 6.57 g/t Ag over a 6.5-metre (m) core length in skarn at Sappho (in hole 10SP03). These and other higher-grade zones are associated with high Cu and are contained within wider anomalous intervals, including a 63.5 m core length zone logged as a pyroxene sulphide skarn with a grade approaching 0.7 per cent copper equivalent derived from current metal prices for Cu, Au, Ag, Pt and Pd.

In addition to drilling, Peter E. Walcott and Associates (PEWA), of Coquitlam, B.C., has mobilized to Greenwood to continue a induced polarization (IP) surface geophysics program that was commenced in early 2026 to follow-up excellent prior results from both surface sampling and historical drilling at the Sappho critical minerals target. A significant chargeability anomaly was identified (see the company's Feb. 26, 2026, news release) and will be followed up with an extension to the phase 1 survey. Induced polarization surveys will also be conducted at the Greyhound-Motherlode area over the coming weeks in the search for additional skarn and porphyry targets.

Sappho prior work highlights:

• The geological setting is the east fault contact of the Toroda graben with numerous pyroxenite-monzonite-diorite (older) and younger QFP-diorite (tertiary) intrusions into intermediate-mafic volcanics along with a complex magnetic feature at the Sappho Crown grant (CG) area;
• The east and west faults of the Toroda graben likely played a role in controlling the Au-Ag mineralization for the Buckhorn skarn and mine to the southwest and the Cu-Au-Ag mineralization for the Motherlode/Greyhound skarns to the north.
• Skarn- and porphyry-style alteration and mineralization along with Cu-PGEs-Au-Ag are observed in outcrop and drill core along with a complex magnetic signature in the Main Sappho CG area.
• Five new sulphide showings were discovered during 2022 fieldwork, with four of the five showings yielding rock grab samples with more than 1 per cent Cu up to as high as 7.25 per cent Cu (see Grizzly's news release dated Nov. 3, 2022).
• A total of 17 rock grab samples returned values more than 1 per cent Cu up to 9.06 per cent Cu, many also with anomalous Au, Ag, Pt and Pd.
• A total of 11 samples have yielded more than 500 parts per billion (ppb) Pt and Pd up to 4.64 grams per tonne (g/t) Pt and up to 2.28 g/t Pd.

The Sappho area is being targeted for copper-gold skarn- and porphyry-type targets associated with a Jurassic alkalic intrusive complex and several younger diorite intrusions. A total of five new showings of copper oxide mineralization were found during the 2022 program. Previous surface sampling and drilling by Grizzly have yielded significant anomalous copper, gold and silver, along with platinum and palladium. Numerous historical and new rock grab samples have yielded greater than 1 per cent Cu, one g/t Au, one g/t Ag, one g/t Pt and one g/t Pd.

Historical 2010 drilling by the company (four core holes) yielded up to 0.31 per cent Cu, 0.75 g/t Au, 0.34 g/t Pt, 0.39 g/t Pd and 6.57 g/t Ag over a 6.5 m core length in skarn at Sappho (in hole 10SP03), including a one m core length intersections of 3.82 g/t Au and 199 g/t Ag, and in a separate sample 1.83 g/t Pt and 2.09 g/t Pd across one m -- these results all are associated with more than 1 per cent Cu in those samples. These higher grade zones were contained within a 63.5 m core length zone logged as a pyroxene sulphide skarn with a grade approaching 0.7 per cent copper equivalent derived from current metal prices for Cu, Au, Ag, Pt and Pd. Drill hole 10SP03 targeted a magnetic anomaly and had no indications of surface mineralization at the time of drilling. One of the new 2022 showings has been found proximal to drill hole 10SP03 and the targeted magnetic anomaly.

Brian "Griz" Testo, president and chief executive officer of Grizzly Discoveries, states: "Geophysics has also outlined multiple new targets across the Sappho project. I am looking forward to seeing what additional IP might show us, and I look forward to identifying some new skarn and porphyry discoveries with drilling."

The company is continuing with surface exploration in the Greenwood area. Crews from APEX Geoscience Ltd. completed soil and rock sampling in August, 2025, through to February, 2026, and the exploration work is continuing. Work, including prospecting, rock and soil sampling, has been conducted at targets in the Rock Creek area, the Midway area, the Copper Mountain area, the Overlander-Attwood area and the Sappho area to date. Additional groundwork, including ground geophysical surveys, is being planned and will comprise IP, magnetics and Loupe electromagnetics (EM) for the Sappho, the Midway and Motherlode areas.
