Churchill Provides Update to Previously Disclosed Frost Cove Results

TORONTO, ON / ACCESS Newswire / May 22, 2026 / Churchill Resources Inc. ("Churchill" or the

"Company") (TSXV: CRI) reports that, as part of its routine geological model construction and

validation using Seequent Leapfrog Geo for the Frost Cove prospect, the Company identified internal

data compilation discrepancies in its March 18, 2026 news release. This news release provides the

validated and corrected analytical results for the affected drill holes.

The intersections under review were from holes FC25 -16, FC25-17, FC25-19, FC25-20, FC25-23,

FC25-24, FC25-26, FC25-27, FC25-28 and FC25-29, located in the southern portion of the Frost Cove

structure, where high -grade massive stibnite has been identified at surface and in the historical

Southern Shaft.

Table 1 presents the validated underlying assays for the same sample intervals. The verified individual

assay data indicate that the mineralized intervals do not support the broader composite intersections

previously reported, which were the result of inadvertent data compilation errors.

Table 2 presents the revised results of interest for holes FC25 -16 to FC25-30, and Table 3 provides

the corresponding drill hole collar location, azimuth, dip and hole length information for the relevant

Frost Cove drill holes. Based on the validated assay data, the principal antimony intersections are

limited to hole FC25-17, which returned 19,990 ppm antimony, or 2.00% Sb, over 0.10 m from 43.02

m, and hole FC25-27, which returned 130,011 ppm antimony, or 13.00% Sb, over 0.57 m from 50.68

m. The most notable gold and silver interval occurred in hole FC25-27, which returned 3.74 g/t Au and

24.95 g/t Ag over 0.55 m. All reported intervals are core lengths, and true widths have not yet been

determined and may be less than the reported core lengths.

Figure 1 presents a plan view of the Frost Cove 2025 final drilling results and 2026 drill hole locations,

while Figure 2 presents a perspective view of the same drilling results and 2026 drill holes. Importantly,

the structural interpretation and overall exploration strategy for the broader Forst Cove prospect [and

Black Raven Project] remain highly active. The northern strike length of Frost Cove, extending

approximately 500 m, remains a priority antimony and gold target for the Company based on

mineralization identified on surface and in prior drilling. The Company has completed nine additional

2026 drill holes intended to further evaluate this target area, with assays pending. At Frost Cove South,

additional surface stripping and trenching are required to better understand the structural complexity

of the zone and to evaluate the potential continuation of the high -grade mineralization identified at

surface and in the historical Southern Shaft.

About the Black Raven Gold-Silver-Antimony Project

The Black Raven Project is a polymetallic exploration asset in central Newfoundland characterized by

high-tenor antimony mineralization interpreted as part of a property-wide gold-silver-antimony system.

Churchill's primary objective is to evaluate the project’s potential as a small -footprint, high -grade

underground mine . In pursuit of this objective, Churchill intends to first gather sufficient data to

undertake the preparation of initial resource estimates and then advance toward the preparation of a

maiden mineral resource estimate in accordance with National Instrument 43 -101, thus, positioning

the property as a potential primary supply source for North American and European markets.

Currently, North America lacks sources of high -grade, primary antimony supply and the potential

domestic source at Frost Cove could be of some significance.

The project encompasses the past-producing Frost Cove Antimony and Stewart Gold mines. While

these sites operated intermittently at the turn of the last century, Churchill is the first exploration group

to apply modern systematic exploration techniques to resource definition through the trend. Black

Raven is located approximately 60 km northwest of Gander, Newfoundland, and approximately 100

km north of the dormant Beaver Brook Antimony Mine. The project benefits from excellent

infrastructure, including r oads, power, proximity to tidewater and ports, and locally integrated

operational and technical teams.

Antimony is recognized as a vital critical mineral, essential for Canada’s national and economic

security. It is a key component in military applications, flame retardants, alloy strengthening in

batteries, and emerging energy storage technologies. Securing a reliable domestic supply chain for

antimony is paramount for critical mineral supply chains, bolstering both economic resilience and

strategic independence.

About Churchill Resources

Churchill Resources Inc. is a Canadian exploration company focused on exploration and evaluation

of strategic and critical metals in Canada, principally at its prospective Black Raven, Golden Baie ,

Taylor Brook and Florence Lake properties in Newfoundland & Labrador. The Churchill management

team, board, and advisors have decades of combined experience in mineral exploration and in the

establishment of successful publicly listed mining companies, both in Canada and around the world.

Churchill’s Newfoundland and Labrador projects have the potential to benefit from the province’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.
