CHURCHILL REPORTS HIGH-GRADE ZINC RESULTS ON POLYMETALLIC VEINS AT THE BLACK RAVEN PROPERTY, CENTRAL NEWFOUNDLAND

Churchill Resources Inc. has released the final due diligence sample results on its Black Raven property with three overlimit zinc assays of 5.25 per cent, 11.03 per cent and 12.11 per cent from grab samples 305, 315 and 321, respectively. These samples returned high-grade gold, silver, lead and zinc, emphasizing the polymetallic metal assemblage of critical minerals present in the Black Raven vein system, per the summary table.

These samples exceeded the laboratory's original upper detection limit for zinc (50,000 parts per million or 5 per cent -- see release of June 23, 2025), and the results reported herein are from the overage assay protocols. The Black Raven vein systems have never been drilled.

"These excellent zinc results complete all of the overlimit ore grade analyses from our due diligence sampling and continue to strongly confirm our belief that the Black Raven system includes high-grade polymetallic veins, as well as the known Frost Cove antimony and Stewart gold past producers," commented Paul Sobie, president of Churchill. "Our next batch of rock samples are at SGS and will be processed much more quickly than the due diligence set as we're running the appropriate ore grade analyses concurrently on suspected high-grade samples."

The Black Raven property hosts two past-producing mines dating back to the late 1800s, the Frost Cove antimony mine and the Stewart gold mine, which returned antimony grades of 35.1 per cent and gold grades of 14.4 grams per tonne, respectively (see release of June 12, 2025). The zinc results reported herein are from different locations on the property. Black Raven is located approximately 60 kilometres northwest of Gander and approximately 100 kilometres north of the Beaver Brook antimony mine, currently on care and maintenance.

Antimony: a critical mineral in high demand

Antimony is a critical mineral essential for national security and modern technology, with over 90 per cent of global production controlled by China, Russia and other non-Western jurisdictions. The metal is a vital component in military applications while also being crucial for certain flame retardants, strengthening alloys in batteries and emerging energy storage technologies. Recent Chinese export restrictions have driven prices to record levels exceeding $50,000 per tonne, highlighting antimony's strategic importance to a fortress North America approach to critical mineral supply chains and making domestic North American sources increasingly important for economic and national security.

Due diligence sampling program

Antimony, gold, silver, lead, zinc, copper and molybdenum samples were selected by Dr. Derek Wilton, independent qualified person to Churchill, during field visits on April 24 and April 25. All samples were labelled and securely bound and delivered to the prep laboratory of SGS Canada Inc. in Grand Falls-Windsor, for crushing and pulverizing. Splits were couriered to Burnaby, B.C., by SGS for GE-AAS33E50 zinc assays and overlimit samples by the GO-ICP90Q100 ore grade analytical method. All due diligence samples described in this news release were grab samples, are selective by nature and are unlikely to represent average grades of the property.

Black Raven antimony-gold property

The Black Raven property comprises nine map-staked licences constituting a single contiguous block of 125 claims that in total cover 3,125 hectares or 31.25 square kilometres. Churchill and the vendors have agreed to a four-kilometre-wide area of interest around the property boundaries as part of their agreement.

The past sampling data reported in this news release are historic in nature and do not meet National Instrument 43-101 standards. Churchill has relied on the information supplied in the government of Newfoundland field assessment reports and from information found in the mineral occurrence database system operated by the Newfoundland Department of Industry, Energy and Technology.

The technical and scientific information in this news release has been reviewed and approved by Dr. Derek H.C. Wilton, PGeo, FGC, who is a qualified person as defined under National Instrument 43-101 (Standards of Disclosure for Mineral Projects). Dr. Wilton is an honorary research professor of economic geology at Memorial University in St. John's and is independent of the company for the purposes of National Instrument 43-101.

About Churchill Resources Inc.

Churchill is a Canadian exploration company focused on strategic, critical minerals in Canada, principally at its prospective Black Raven, Taylor Brook and Florence Lake properties in Newfoundland and Labrador. The Churchill management team, board and advisers have decades of combined experience in mineral exploration and in the establishment of successful publicly listed mining companies, both in Canada and around the world. Churchill's Newfoundland and Labrador projects have the potential to benefit from the province's large and diversified mineral industry, which includes world-class nickel mines and processing facilities, and a well-developed mineral exploration sector with locally based drilling and geological expertise.

Churchill's Taylor Brook nickel-copper-cobalt-vanadium-titanium property and Florence Lake nickel property are both in good standing for a number of years, such that further exploration and development can await improved market conditions sentiment while the company focuses on high-grade antimony-gold and other critical minerals.
