Churchill Resources drills 7.25% antimony over 1.98 metres at Black Raven Project, near Southern Shaft along 800-metre strike at Frost Cove, Newfoundland

Churchill Resources Inc. [TSXV: CRI] reported exceptional final results from its 2025 maiden drilling and trenching program at the Black Raven Project in central Newfoundland, as highlighted in the following points: Frost Cove Antimony Mine Prospect: Final 2025 holes FC25-16 to 30 returned standout results including 6.44% Sb over 2.06 metres, 7.25% Sb over 1.98 metres, 4.84% Sb over 1.00 metre and 3.94% over 1.60 metres.

A locally adjacent parallel polymetallic (gold-silver) vein intersected a best result of 5.89 g/t Aueq over 1.00 metre. This demonstrated potential high-grade antimony mineralization over an 800-metre strike length with vertical depth of 100 metres; remaining open in all directions.

New Polymetallic System Discovered at Taylor’s Room Prospect: A new polymetallic system has been identified at Taylors Room, with trenching and channel sampling over 150 metres of strike yielding a best results of 10.59 g/t Aueq over 1.05 metres and 4.12 g/t Aueq over 1.80 metres.

A 12-hole drill program intersected shear-vein zone at shallow depths, but returned lower gold tenors than at surface (best assay 3.15 g/t Aueq over 0.44 metres).

Drill core fire assay samples to be optimized by retesting with much larger pulp and metallic aliquots to confirm gold content.

2026 Exploration Underway; drill program commencing: A two-rig drill program is scheduled to begin with first rig on March 23, with a second rig arriving mid-April.

Trail and drill pad construction has commenced at site, as well as drill contractor pre-mobilization of equipment to Churchill’s project facility near Boyd’s Cove, approximately 30km from the site.

Frost Cove extension drilling and Pomley Cove Pond targets will be the initial priorities, with details on planned drilling and trenching to be articulated in a forthcoming news release.

Paul Sobie, President of Churchill Resources, commented: “Today we are confirming elevated antimony assays at Frost Cove along the entire known structure comprising an 800m length with a vertical depth to 100 metres. Potentially commercial grades and thicknesses of stibnite reported from numerous locales at surface, and to shallow depths.

“The parallel, high-grade gold-silver shear at Frost Cove has now been traced for 500 metres along the same quartz-feldspar porphyry dyke. Further drilling to explore the strike length of the Frost Cove mineralization both to the north and south can commence shortly, along with infill drilling of gaps. With Taylor’s Room and Pomley Cove Pond suggesting polymetallic potential, and Frost Cove also looking very positive, we’re excited to get the drills turning again at the end of the month. Drill holes at Pomley Cove Pond will be targeted on newly generated, coincident IP chargeability, and gold-silver-arsenic soil anomalies.”

Conan McIntyre, Churchill CEO, said: “Our 2025 exploration at Black Raven has been a resounding success. From intersecting over 7% antimony over 2 meters within 800 metres of strike at Frost Cove, to a new polymetallic gold-silver discovery at Taylors Room and our previously reported discovery of a high-grade gold-silver-lead-zinc system at Pomley Cove Pond, we are proving the exceptional quality and scale of this asset. These results also reinforce that, together with our recent transaction announcement for Golden Baie, Churchill is seeking to control the two premier high-grade antimony-gold projects in the province, both within 100km on either side of the Beaver Brook Mine, which accounted for virtually all of North America’s primary antimony production in the 21st Century when it was in operation.”

These results are the last, save for a few over-limit assays, from Churchill’s Fall 2025 exploration program at the Black Raven Project, which was the first modern exploration of the Frost Cove Mine structure for antimony, and high-grade polymetallic mineralization at the other known prospects throughout the Property. This maiden program consisted of 50 diamond drillholes, with a cumulative depth of 5,176 metres, along with extensive channel and 2,200 soil samples. Thirty holes, totalling 2,743 metres depth, were drilled at Frost Cove with the remaining holes completed on adjoining targets at Stewart, Taylor’s Room, and the “wildcat” program at Pomley Cove Pond. This news release provides results for 14 Frost Cove drillholes along the southern 400 metres of the mineralized structure, as well as six channel samples and twelve drill holes at Taylor’s Room Prospect, and six drill holes which evaluated the historic Stewart Gold Mine prospect; these latter six holes only encountered a single narrow mineralized quartz vein thus no further exploration is planned at Stewart.

The Black Raven Project is a polymetallic exploration asset in central Newfoundland characterized by high-tenor antimony mineralization and a perceived property-wide gold-silver-antimony system. Churchill’s primary objective is to evaluate the project’s potential as a small-footprint, high-grade underground mine, intending first to gather sufficient data to support the preparation of initial resource estimates and advance towards the formulization of a NI 43-101 compliant maiden resource, thus positioning the property as a potential primary supply source for North American and European markets. Currently, North America lacks sources of high-grade, primary antimony supply, making a potential domestic source at Frost Cove critically important.

The project encompasses the past-producing Frost Cove Antimony Mine and Stewart Gold Mine. While these sites operated intermittently at the turn of the last century, Churchill is the first to apply modern systematic exploration techniques to resources definition for the trend. Black Raven is located approximately 60km northwest of Gander, Newfoundland, and approximately 100km north of the dormant Beaver Brook Antimony Mine. The project benefits from excellent infrastructure, including roads, power, proximity to tidewater and ports, and locally integrated operational and technical teams.

Antimony is recognized as a vital critical mineral, essential for Canada’s national and economic security. It is a key component in military applications, flame retardants, alloy strengthening in batteries, and emerging energy storage technologies. Securing a reliable domestic supply chain for antimony is paramount for critical mineral supply chains, bolstering both economic resilience and strategic independence.

Churchill Resources is focused on exploration and evaluation of strategic and critical metals in Canada, principally at its prospective Black Raven, Taylor Brook and Florence Lake properties in Newfoundland & Labrador. The Churchill management team, board, and advisors 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.
