Silver (1,118 g/t), 1.2km to the North of Historic Frost Cove Antimony Mine; Metallurgical
Studies Underway
TORONTO, August 6th, 2025 (GLOBE NEWSWIRE) -- Churchill Resources Inc. (“Churchill”
or the “Company”) (TSXV: CRI) is pleased to announce June prospecting work on its Black Raven
property has identified very high -grade antimony ( 9.46% Sb) (Sb = Antimony), gold ( 35.5 g/t
Au), and silver (1,118 g/t Ag) mineralization nearly1.2km 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% 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 CEO, “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,
pictured below, where gold-silver-antimony veins have also now been identified and which trend
towards the Frost Cove Antimony Mine. Churchill is also pleased to announce that, overall, 30 of
55 samples taken during the June program were highly mineralized, including:
• high-grade antimony samples from both the Upper (18.42% Sb) and Lower Adit (>20.0%
Sb) at the past-producing Frost Cove Mine;
• high-grade antimony samples from historical pits ~350m to the south along strike from the
historical adits of the Frost Cove Mine (13.66% Sb, 11.02% 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, 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 flowsheets.

“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 Har bour Head gossan, nearly 1.2km north of the adits and trend towards
Frost Cove. We are also excited by the continuity of the antimony veins seen underground for
over 60m in the Lower Adit, over 25m in the Upper Adit, and in pits 350m along strike of the host
dyke 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 (50kg and 15kg, respectively) of composite
Frost Cove antimony-rich vein material at two industry facilities, SGS Lakefield using traditional,
and ReElement Technologies Corporation ( www.ReElementTech.com) for chromatography
processing flowsheets. Results from these studies and our July prospecting will be released as
received in the coming weeks.”

The figure above and table below provide the locations and critical metal assay results for the 30
samples, of which all but three were composite grab samples reasonably representative of the entire
vein. Samples 238001 -003 were representative channels taken from the Up per Adit. The other
25 samples were variably mineralized and lower grading than those presented here.
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 12th 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. The
metal is a vital component in military applications, while also b eing 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 im portance 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 now 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 detailed in the table. 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 s elective by nature and unlikely to represent average grades of the
property.
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.
