Metallis Resources Reports Positive Drilling Results from Idaho's Greyhound Property

Metallis Resources reports strong progress from mid-season drilling at its Greyhound Property in Idaho. The company is focused on gold, copper, nickel, and silver exploration at its 100%-owned Kirkham Property in British Columbia, Canada. The Kirkham Property is located in the Golden Triangle's Eskay Camp, near past-producing Eskay Creek mine and major deposits at Seabridge Gold's KSM and Newcrest Mining's Brucejack mine.

VANCOUVER, BC, Oct. 9, 2025 /CNW/ - Integra Resources Corp. ("Integra" or the "Company") (TSXV: ITR) (NYSE American: ITRG) has announced strong progress from its 2025 growth drilling program at the Florida Canyon Mine located in Nevada. The drill program, which marks the first phase of a multi-year growth strategy, aims to expand mineral resources and reserves, extend mine life, and enhance the value of Florida Canyon.

The 2025 growth drilling program consists of 16,000 meters of reverse circulation ("RC") and sonic drilling, focused on three key areas: near-surface oxide potential from historical low-grade gold-mineralized waste material, expanding in-situ resources between existing mine open pits, and testing lateral extensions and in-pit infill drilling. As of the date of this news release, approximately 13,000 meters of drilling have been completed.

Opportunity 1: Near-Surface Oxide Potential from Historical Dump Material

Drilling targeting large volumes of historical, gold-mineralized, low-grade waste material that was uneconomic at lower gold prices has shown promising results. Initial drill results from the South Dump have demonstrated near-term oxide growth potential at Florida Canyon. For example, intercepts such as FCM25-0646 (0.21 g/t oxide Au over 73.2 m) and FCM25-0652 (0.20 g/t oxide Au over 68.6 m) suggest significant near-surface gold mineralization. Metallurgical bottle roll leach tests are underway to assess potential gold recoveries and other ore characteristics, with preliminary indications suggesting favorable heap leach characteristics.

Opportunity 2: Expanding In-Situ Resources Between Existing Mine Open Pits

The drill program is also focused on expanding gold resources within "saddle" and "ridge" zones located between existing open pits. Historical drilling has demonstrated encouraging intercepts of mineralization at or near-surface. For instance, FCM25-0592 (0.48 g/t Au over 76.2 m, incl. 8.03 g/t Au over 1.5 m) and FCM25-0625 (0.81 g/t Au over 76.2 m, incl. 14.87 g/t Au over 1.5 m) highlight the potential for significant gold mineralization in these areas.

The 2025 drill program is expected to support a mineral resource and reserve update and a revised life-of-mine plan in the first half of 2026. George Salamis, President, CEO, and Director of Integra commented: "We are pleased to see additional success from our 2025 near-mine oxide drilling campaign at Florida Canyon. Building on initial results released in August, we continue to see excellent gold-mineralized intercepts in both the historical dump and Inter-Pit areas, which confirm excellent grade continuity and continue to highlight the potential to grow mineral resources and extend mine life."
