Churchill Resources Inc. (CVE: CRI) reported significant high grade mineralization from its June prospecting program at the Black Raven property in Newfoundland.
On Thursday, the company reported new veins with impressive concentrations of antimony, gold, and silver, expanding the potential strike length of the system and confirming mineralization at depth. These findings support the company’s belief in a robust polymetallic mineralizing system stretching beyond historical workings.
The standout discovery came from Moreton’s Harbour Head, roughly 1.2 kilometres north of the historic Frost Cove Antimony Mine. Here, Churchill collected samples that returned values of 9.46 per cent antimony, 35.5 grams per tonne gold, and 1,118 grams per tonne silver. These values rank among the highest ever reported from the property. Furthermore, initial sampling from the Lower Adit at Frost Cove exceeded 20 per cent antimony.
“With the increase in strike length and confirmation of antimony at depth, we are looking forward to our upcoming trenching and drilling programs,” said Conan McIntyre, CEO of Black Raven.
In addition, 30 out of 55 samples collected during the June program returned highly mineralized results. The program yielded numerous high-grade antimony hits from both the Upper Adit (18.42 per cent Sb) and Lower Adit (over 20 per cent Sb). Historical pits located about 350 metres south of the adits returned samples of 13.66 per cent and 11.02 per cent antimony, respectively.

Antimony veins confirmed for over 60 meters
Gold also showed promise in rubble from the Stewart Mine, where assays returned 6.4 grams per tonne. Additionally, the Taylor’s Room Prospect produced polymetallic samples grading 2.2 grams per tonne gold and 24 grams per tonne silver.
“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,” said President Paul Sobie.
“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.”
Churchill also highlighted structural continuity. Antimony veins have now been confirmed for over 60 metres in the Lower Adit and more than 25 metres in the Upper Adit. Additionally, pits located 350 metres south of Frost Cove show similar mineralization along strike, indicating a cohesive and extensive system.
Further supporting its exploration efforts, Churchill has launched metallurgical studies on antimony-rich vein material. The company sent composite samples weighing 50 kilograms and 15 kilograms, respectively, to two different facilities. Traditional flotation tests are underway at SGS Lakefield, while ReElement Technologies Corporation is conducting chromatography based processing studies.
These studies aim to determine optimal recovery methods and further evaluate the economic potential of the Frost Cove deposit. Churchill expects results from both the metallurgical work and its July field program in the coming weeks.

Chinese exports push prices over $50K per tonne
Antimony is a critical mineral essential to national defense, flame retardants, batteries, and next generation energy storage. Over 90 per cent of global supply comes from China, Russia, and other non Western jurisdictions. As such, Churchill’s Black Raven project aligns with North American efforts to reduce reliance on foreign sources of critical minerals.
Chinese export restrictions have recently pushed antimony prices beyond $50,000 per tonne. Accordingly, domestic sources such as Black Raven are gaining importance for both economic security and defense supply chains.
These high antimony prices have changed the economic equation for junior exploration companies. Smaller producers now see antimony not merely as a byproduct but as a strategic driver for project viability.
Companies like NevGold Corp‘s (CVE: NAU) (OTCMKTS: NAUFF) (FRA: 5E50), historically focused on gold exploration, are beginning to evaluate the potential of critical minerals like antimony to diversify revenue streams and attract investment. With global supply dominated by China and Russia, the surge in price has made even modest antimony showings economically significant. Additionally, projects with gold-antimony potential are increasingly viewed as hedges against volatile precious metals markets and gateways to government backed funding.
For example, in the United States, the push to develop domestic critical mineral supply chains has taken legislative form through the FAST-41 (Fixing America’s Surface Transportation Act, Title 41) program. FAST-41 provides a streamlined federal permitting process for projects essential to national interest, particularly in energy, infrastructure, and critical minerals.
