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.

_* Gold equivalent values (AuEq) were calculated using long-term metal price assumptions of US$3,000/oz Au, US$45/oz Ag, US$4.10/lb Cu, US$0.85/lb Pb, US$1.30/lb Zn and US$20/lb Sb, and assumed recoveries of 95% for all metals. The Company cautions that metallurgical recoveries have not been established for all metals and that metal equivalent values are provided for comparative purposes only._

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 roads, 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.

Qualified Person

The technical and scientific information in this news release has been reviewed and approved by Dr. Derek H.C. Wilton, P.Geo., FGC, who is a "qualified person" as defined under National Instrument 43-101 - _Standards of Disclosure for Mineral Projects _("NI 43-101"). Dr. Wilton is an honorary research professor of Economic Geology at Memorial University in St. John's and is independent of the Company for the purposes of NI 43-101. The Qualified Person reviewed the corrected assay database, original assay certificates, sample intervals, drill logs, QA/QC results, compositing calculations, and updated geological model.

Sampling Program

Antimony, gold, silver, lead, zinc, copper and molybdenum samples were collected by Company geologists from drill cores, channel samples, and grab samples. Core samples were halved by saw at the Company's core facility near Boyd's Cove. All samples were labelled and securely packaged and delivered to the laboratory of Eastern Analytical in Springdale, NL, for crushing and pulverizing. Splits were analysed by Au 30 g fire assay and ICP-34 protocols and by EA's ore-grade analytical methods when the initial detection limits were exceeded. Antimony samples from Frost Cove drill holes were prepped by Eastern and the pulps sent to SGS Canada Inc. in Lakefield, Ontario, for their GE_AAS33E50 assay protocols and their ore-grade analytical methods when the initial detection limits were exceeded. Qualified Person Dr. Derek Wilton has examined all of the channel sampling sites and all drill holes reported herein.

Data Verification

As part of the correction process, the Company and the Qualified Person reviewed the original laboratory certificates against the assay database, verified sample intervals against drill logs, recalculated reported composite intervals, and compared the corrected assay database against the updated geological model. The corrected results presented herein supersede the results reported on March 18, 2026.
