CHURCHILL DISCOVERS HIGH GRADE ANTIMONY (9.46% SB), TOGETHER WITH GOLD (35.5 G/T) AND SILVER (1,118 G/T), 1.2KM TO THE NORTH OF HISTORIC FROST COVE ANTIMONY MINE; METALLURGICAL STUDIES UNDERWAY

Churchill Resources Inc.'s June prospecting work on its Black Raven property has identified very high-grade antimony (9.46 per cent Sb), gold (35.5 grams per tonne Au) and silver (1,118 g/t Ag) mineralization nearly 1.2 kilometres to the north of the Historic Frost Cove antimony mine. In addition, the first samples taken from the lower adit at the Frost Cove mine returned over 20 per cent antimony, thus demonstrating depth potential for the mine.

"These results show that Churchill has identified veins which consist of high-grade antimony and encouragingly coincident with high-grade precious metals both north and south of the historic workings," commented Conan McIntyre, Churchill's chief executive officer. "With the increase in strike length and confirmation of antimony at depth, we are looking forward to our upcoming trenching and drilling programs."

The latest results come from samples taken from a large gossan at Moreton's Harbour Head, where gold-silver-antimony veins have also been identified and which trend toward the Frost Cove antimony mine. Churchill is also pleased to announce that, over all, 30 of 55 samples taken during the June program were highly mineralized, including:

• High-grade antimony samples from both the Upper (18.42 per cent Sb) and Lower adit (greater than 20.0 per cent Sb) at the past-producing Frost Cove mine;
• High-grade antimony samples from historical pits approximately 350 metres to the south along strike from the historical adits of the Frost Cove mine (13.66 per cent Sb and 11.02 per cent Sb);
• Samples with enriched gold from rubble at the Stewart mine (6.4 g/t Au); and
• Polymetallic samples from the Taylor's Room prospect (2.2 g/t Au and 24 g/t Ag).

Churchill also reports that it has commenced metallurgical studies on vein material taken from the Frost Cove mine at two industry facilities for both traditional flotation and newly developed chromatography processing flow sheets.

"These excellent results continue to confirm our strong 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. "We are consistently seeing multiple metal pulses in the polymetallic veins at Black Raven that are suggestive of a large, vibrant high-grade mineralizing system. It is particularly exciting that high-grade gold-silver-antimony veins occur at the Moreton's Harbour Head gossan, nearly 1.2 km north of the adits and trend towards Frost Cove. We are also excited by the continuity of the antimony veins seen underground for over 60 m in the Lower adit, over 25 m in the Upper adit, and in pits 350 m along strike of the host dike to the south at Frost Cove. Our July work continued to impress and add to our understanding. We've initiated metallurgical studies of large samples (50 kg and 15 kg, respectively) of composite Frost Cove antimony-rich vein material at two industry facilities, SGS Lakefield using traditional and ReElement Technologies Corp. for chromatography processing flow sheets. Results from these studies and our July prospecting will be released as received in the coming weeks."

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 g/t, respectively (see news release of June 12, 2025). The results reported herein are from different locations on the property. Black Raven is located approximately 60 kilometres northwest of Gander and approximately 100 km 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.

Prospecting sampling program

Antimony, gold, silver, lead, zinc, copper and molybdenum samples were collected by company geologists and prospectors during June, with Dr. Wilton revisiting/resampling high-grade sites in July, with all July samples submitted. All samples were labelled and securely bound and couriered delivered to SGS Canada Inc. in Burnaby, B.C., by SGS for GE-AAS33E50 assays and by the ore-grade analytical methods. All samples described in this news release were grab samples, with the exception of three short channel samples taken in the Upper adit at Frost Cove, and thus are selective by nature and 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.
