Churchill Reports More High-Grade Gold and Silver Vein Results near Past-Producing Frost Cove Antimony Mine, Including 17.3 g/t Au and 130 g/t Ag

TORONTO, Sept. 15, 2025 (GLOBE NEWSWIRE) -- Churchill Resources Inc. (“Churchill” or the “Company”) (TSXV: CRI) is pleased to announce further sample results from July prospecting work on its Black Raven property, host to the past-producing Frost Cove Antimony Mine and Stewart Gold Mine, covering areas away from the historical mines and prospects. Fourteen of 70 samples were from highly mineralized new veins with these highlighted in the table and figure below:

"Work at the Black Raven polymetallic system continues to deliver high grade veins away from the known mines and prospects, as our teams prospect the property in advance of our drilling and trenching program, with the drill contractor mobilizing to the Frost Cove site today, September 15th," said Paul Sobie, President. “These latest gold-silver-antimony results should be considered in the context of the high-grade antimony at the historic Frost Cove Mine, part of the same mineralized vein system, and the Stewart Gold Mine, that have returned grades up to 14.4 g/t gold and 56.7 g/t Ag.

The Taylor’s Room and Morton Harbour Head prospects to the north of Frost Cove continue to return very high-grade results from newly samples veins that add to their attractiveness for follow-up work. Soil sampling is systematically covering the property and is expected to generate new target areas for follow-up later this year.”

The Black Raven Property hosts two past-producing mines dating back to the late 1800’s, the Frost Cove Antimony Mine, and the Stewart Gold Mine which returned antimony grades of 35.1% and gold grades of 14.4 g/t, respectively (see release of 12^th June 2025). The results reported herein are from different locations on the property (see attached map). Black Raven is located approximately 60km northwest of Gander, and approximately 100km 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% of global production controlled by China, Russia, and other non-Western jurisdictions. It is a vital component in military applications, while also being crucial for certain flame retardants, strengthening alloys in batteries, and emerging energy storage technologies. Antimony is essential to a “Fortress North America” approach to critical mineral supply chains and making domestic North American sources increasingly important for economic and national security.

Prospecting Sampling Program

Antimony, gold, silver, lead, zinc, copper and molybdenum samples were selected by Company geologists and prospectors during July. 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 assays and by the ore-grade analytical methods detailed in the table. All samples described in this news release were grab samples, and are selective by nature and are unlikely to represent average grades of the property. Qualified Person Dr. Derek Wilton has examined all of the sites reported herein, and selected due-diligence samples as required from the same veins designated DW-3XX.

Black Raven Antimony-Gold Property

The Black Raven Property comprises nine map-staked licenses constituting a single contiguous block of 125 claims that in total cover 3,125ha or 31.25km². Churchill and the vendors have agreed to a 4km wide area of interest around the property boundaries as part of their agreement.

The technical and scientific information in this news release has been reviewed and approved by Dr. Derek H.C Wilton, P.Geo., FGC, who is a “qualified person” as defined under National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”). 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 NI 43-101.

FORWARD-LOOKING STATEMENTS

This news release contains certain forward-looking statements, including, but not limited to, statements about Churchill’s objectives, goals and exploration activities proposed to be conducted on its properties; future growth potential of Churchill, including whether any proposed exploration programs at any of its properties will be successful; exploration results; and future exploration plans and costs. Wherever possible, words such as “may”, “will”, “should”, “could”, “expect”, “plan”, “intend”, “anticipate”, “believe”, “estimate”, “predict” or “potential” or the negative or other variations of these words, or similar words or phrases, have been used to identify these forward-looking statements. In particular, this release contains forward-looking information relating to, among other things, the Company’s goals and objectives, and future exploration work to be conducted on the Company’s Black Raven Antimony Property. These statements reflect management’s current beliefs and are based on information currently available to management as at the date hereof.

Forward-looking statements involve significant risk, uncertainties and assumptions. Many factors could cause actual results, performance or achievements to differ materially from the results discussed or implied in the forward-looking statements. These factors should be considered carefully and readers should not place undue reliance on the forward-looking statements. Such factors, among other things, include: exploration results on the Black Raven Antimony Property; the expected benefits to Churchill relating to the exploration proposed to be conducted on its properties; receipt of all regulatory approvals in connection with the transaction contemplated herein; failure to identify any additional mineral resources or significant mineralization; the preliminary nature of metallurgical test results; uncertainties relating to the availability and costs of financing needed in the future, including to fund any exploration programs on the Churchill’s properties, if required; fluctuations in general macroeconomic conditions; fluctuations in securities markets; fluctuations in spot and forward prices of gold, silver, base metals or certain other commodities; change in national and local government, legislation, taxation, controls, regulations and political or economic developments; risks and hazards associated with the business of mineral exploration, development and mining (including environmental hazards, industrial accidents, unusual or unexpected formations pressures, cave-ins and flooding); inability to obtain adequate insurance to cover risks and hazards; the presence of laws and regulations that may impose restrictions on mining and mineral exploration; employee relations; relationships with and claims by local communities and indigenous populations; availability of increasing costs associated with mining inputs and labour; the speculative nature of mineral exploration and development (including the risks of obtaining necessary licenses, permits and approvals from government authorities); the unlikelihood that properties that are explored are ultimately developed into producing mines; geological factors; actual results of current and future exploration; changes in project parameters as plans continue to be evaluated; soil sampling results being preliminary in nature and are not conclusive evidence of the likelihood of a mineral deposit; and title to properties. Although the forward-looking statements contained in this news release are based upon what management believes to be reasonable assumptions, the Churchill cannot assure readers that actual results will be consistent with these forward-looking statements.
