Churchill Very Pleased to Report High Grade Antimony >10%Sb, and Gold >10g/t Au at Black Raven Past-Producers, NL
Churchill Very Pleased to Report High Grade Antimony >10%Sb, and Gold
>10g/t Au at Black Raven Past-Producers, NL
TORONTO, May 28, 2025 -- Churchill Resources Inc. (" Churchill") is extremely pleased to announce that due-diligence
sampling at the historical Frost Cove Antimony and Stewart Gold mines on the Black Raven property returned assays of >10%
antimony and >10g/t gold, respectively. These samples exceeded the detection limit for those elements, and further assay
work is underway to determine their precise metal contents. The Frost Cove Antimony Veins and host felsic dyke have been
traced over 800m on surface, with numerous historical samples grading >1% Sb (the upper detection limit of the historical
assays), and has never been drilled.
"These exceptional results further validate the Company’s strategic pivot to antimony and gold at Black Raven’s past-
producing mines, and underscores the entire property’s significant potential. They confirm and expand upon historical records
from the property reported in our news release of April 14 th, 2025. Further successful exploration at Frost Cove confirming
these grade tenors along strike would place it among the highest-grade antimony projects globally. Finally, Churchill is very
pleased to announce the execution of the definitive agreement dated May 6th, 2025 to acquire a 100% undivided interest in the
Black Raven Antimony Property, from property owners Eddie and Roland Quinlan." said Paul Sobie, Chief Executive Officer of
Churchill.
The Black Raven property encloses the two small-scale past producing mines which operated between 1890 and 1918
exploiting stibnite, gold and arsenopyrite. The mines and numerous related occurrences constitute an extensive high-grade
hydrothermal system carrying gold, antimony and silver in veins and stockworks. The historical mines and other occurrences
are located within close proximity to each other, in a larger-scale geological environment defined by intense veining and
alteration associated with felsic intrusions. For the first time in the project’s history, the entire mineralized system has been
consolidated for systematic, state-of-the-art exploration.
Highlights:
• Frost Cove Antimony Mine adits are in excellent condition for systematic sampling, CRI grab samples from the
two known veins in upper adit assayed >10% Sb
• Detailed sampling of both adits, and ~800m of known surface strike extent, with trenching and channel
sampling, will commence in June
• Numerous other historical high-grade gold-silver veins confirmed including the past-producer Stewart Gold
Mine – large hydrothermal system confirmed which is also to be evaluated with trenching/stripping/channel
sampling
• Additional high-grade Au-Ag-Sb prospects not yet re-sampled
The Black Raven Property is located approximately 60km northwest of Gander, Newfoundland and Labrador, and hosts two
past-producing mines dating back to the late 1800’s, the Frost Cove Antimony Mine, and the Stewart Gold-Antimony Mine.
The Black Raven Property is located approximately 100km north of the Beaver Brook Antimony Mine, which is currently under
care and maintenance. It is reported that the owners are actively exploring for more deposits to feed the mill.

Black Raven, like all of Churchill’s projects, is strategically located in Newfoundland and Labrador, which boast access to
North American and European markets, proximity to deep water ports, exceptional power infrastructure and transportation
networks. Like all of Churchill’s projects, Black Raven also benefits from Newfoundland & Labrador’s large and diversified
minerals industry, which includes world class mines and processing facilities, and a well-developed mineral exploration sector
with locally based drilling and geological expertise.
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 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.
Due-Diligence Sampling Program
Antimony, gold and silver assay data from historical surface grab samples are presented in the figure below along with the
2025 Wilton due-diligence sample assays. Due-dilligence samples from several of the other prospects on the property
returned high gold, lead, and zinc values per the figure and table below, with silver assays still pending. Importantly, reportedly
high-grade occurrences at M.H. (Morton Harbour) Head, M.H.1 and M.H.2 were not able to be sampled during this first tour of
the property.
All samples were selected by Dr. Derek Wilton, independent QP to Churchill, during field visits on April 24 th and 25 th in the
company of Mr. Sobie and two senior field technicians, and led by vendor Roland Quinlan. 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 assay work with analytical methods per the table below. Over-limit samples
are currently receiving ore-grade assay work to determine precise metal contents. All due-diligence samples described in this
news release were grab samples and are selective by nature and are unlikely to represent average grades of the property.
Frost Cove Antimony Mine – the historical workings are intact and as described by Heyl (1936), with a lower adit just above
sea-level on the coast, and the upper adit commencing ~50m to the south, ~15m above the lower adit. It was not possible to
examine the lower adit due to ice blockage, but the upper adit was accessible per the photos below and extends ~15m to a
face where the antimony veins and host quartz feldspar dyke are exposed. The mine exploited two quartz-antimony veins
intruded along the margins of the dyke over a stope width of ~2.5m. A considerable amount of material has been mined out
between the surface and the entrances to the two adits. The host dyke and associated quartz-antimony veins have been
mapped and sampled over ~800m per the figure with several pits reporting elevated historical sampling results.
Samples DW 307 and 308 are from the massive sulphide portions of the two quartz-antimony veins (HW and FW veins) and
both assayed above the detection limit of >10% Sb. The foot wall vein is ~50cm in width, and the hanging wall vein ~15cm in
width at the sample site in the upper adit, with impressive massive stibnite zones within the veins, per photos below.
Sample 306 was quartz-carbonate-qfp (quartz-feldspar-porphyry)-antimony vein material from rubble at the mouth of the lower
adit, and it assayed 3.32% Sb (with modest Zn).
Follow-up work has commenced as CRI crews have completed clearing away trees from the mined-out stope to provide safe
access and better exposure. Plans are in place to collect several channel samples from both adits, as well as systematically
sample at surface along the known 800m strike through mechanical trenching/stripping/channel samples. Several affiliated
veins to the main one, based on the Heyl’s (1936) mapping will be investigated.
The table below provides assays received to-date for all 24 due-diligence samples.
Stewart Gold Mine – the site has been rehabilitated with the shaft and all pits covered and filled with gravel. Sample 302
quartz-arsenopyrite vein material from a very lean rubble pile (virtually all waste) assayed >10g/t. Follow-up planning for a
trenching and drilling program at Stewart is commencing.
Nearby Gold Vein s to Stewart Mine – Sample 303 assayed 7.51 g/t Au (plus modest Pb and Zn). In samples 304-305 from
veins across the harbour and along trend –both samples returned 7.7g/t Au (plus modest Cu, higher tenor Pb and Zn).
Arsenopyrite is the predominant sulphide within these narrow <0.5m veins.
Taylor’s Room Gold Prospect – only rubble piles were located thus far, as overburden and forest cover obscure the veins
and pits have been filled in. CRI sampling didn’t confirm previously reported high values, with the best sample DW-310 grading
1.98 g/t Au from weathered arsenopyrite vein material. The CRI crew has completed cutting down the very thick trees and
bush cover over these veins for better sampling access. The historical shaft is still present albeit full of water.
Nearby Veins to Taylor’s Room Veins – two different narrow quartz-carbonate-arsenopyrite veins (samples DW-314 and DW
-315) graded 5.81 and 5.09 g/t Au respectively with DW-315 returning very high Pb and Zn assays.
Morton’s Harbour Pond/Western Copper – collectively these two prospects exhibit characteristics of a large-scale (~1km
diameter) porphyry mineralization target based on wide-spread, intense stockwork veining carrying modest gold, copper, silver
and molybdenum contents based on historical work. Low but encouraging values in Au, Mo, Zn were returned for samples DW-
319 to 321 and 323 with one quartz vein sample (DW-321) grading 2.16 g/t Au (plus low copper, high Pb and Zn). At Western
Copper – low Cu values were returned from three samples collected at past surface channel sampling, DW-316 to 318. CRI
has compiled the results from the four Winkie holes drilled by Eddie Quinlan in 2024 which intersected mineralized Cu-Au-Ag
stockwork in altered felsic volcanic rocks (0.1-0.3% Cu, 50-350ppb Au plus Ag) from collar to their end of holes at ~60m. CRI
also has compiled 2012 Induced Polarization survey work over the larger porphyry target to plan follow-up trenching and drilling
for the summer.
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 31.25km 2. Churchill and the vendors have agreed to a 4km wide area of interest around the property
boundaries as part of their agreement.
Churchill intends to immediately commence its sampling program on the surface showings and any accessible historical
workings following compilation of all historical data is complete. The entire property will be surveyed with LiDAR and
orthophotos as soon as the Government permit has been received. Follow-up prospecting and systematic trenching, with
channel sampling work as required, are being planned for initiation in June based on the compiled database. The derived
geological and geochemical data will used to outline drill targets along strike and at depth to the historical workings.
The past sampling data reported in this News Release is historic in nature and does not meet NI43-101 standards. Churchill
has relied on the information supplied in the Government of Newfoundland field assessment reports and from information found
in the Mineral Occurrence Database System operated by the Newfoundland Department of Industry, Energy and, Technology.
