Cleghorn Proceeds with Field Work at Rocco Copper Prospect, Gaspé, Québec
Sample analyses remain pending after preliminary survey interpretation identified two priority targets for skarn-related mineralization.
Sentiment and the balance of points
Rhea-AI Sentiment reads the wording of the document, how positive or negative its language is on a 1 to 5 scale. The balance of points shown with the takes weighs what the document actually discloses, so the two can disagree, for example when a trial that missed its main goal is described in upbeat language.
Rhea-AI Summary
Cleghorn Minerals (CLGMF) completed airborne surveys and ground exploration at its Rocco Copper Prospect in Gaspé, Québec, identifying priority exploration targets. The late-August 2026 survey covered 1,405 line-kilometres. Preliminary interpretation outlined two intense circular magnetic anomalies associated with intrusive bodies in calcareous mudstone, identified as priority targets for skarn-related mineralization.
A seven-person team conducted two weeks of ground follow-up, mapping about 80% of the property; the northwest corner was inaccessible. Crews collected 139 grab or chip samples and 82 stream sediment samples. All analytical results, including petrographic studies examining rock composition and alteration, remain pending. Cleghorn also granted options to purchase 1,150,000 common shares at $0.105 each over five years.

Val-D'Or, Québec--(Newsfile Corp. - October 22, 2026) - Cleghorn Minerals Ltd. (TSXV: CZZ) ("Cleghorn" or the "Company") is pleased to confirm that exploration programs were initiated on the Rocco Copper Prospect located in Gaspé, Québec beginning in August with airborne magnetic and electromagnetic (AEM) surveys, together with immediate ground follow-up by a 7-person prospecting team. In parallel, a geochemical sampling program was conducted to test for skarn indicator minerals.
Location and Access: The Rocco Copper Prospect, acquired by map-designation ("staking") of 99-claims (5,467-hectares) in NTS Map Sheet 22A/11, is located in the Gaspé peninsula of eastern Québec (Gaspé region), ~100 km north of Port-Daniel or 100 km south-east of Murdochville, approximately 830 km northeast of Montréal, Québec. Direct access is available through a dense network of forestry roads in the area. As announced on July 22, 2026, the claims were acquired for their geological potential, considered by management and local geological consultants to be prospective for the discovery of a porphyry copper-skarn mineralized system.
Geological Setting: The Rocco Copper Prospect encompasses sedimentary rocks (shales and calcareous mudrocks of the Ordovician Burnt Jam Brook and White Head formations), separated from the calcareous mudrock of the Devonian Fortin Group and Cap Bon Ami Formation by the Grande-Rivière Fault and injected by numerous porphyry dykes of the Lemieux intrusive suite, Siluro-Devonian in age, and similar to the porphyry dykes associated with the Murdochville porphyry system, host to the Gaspé Copper Mountain Mine.
Similarities with the geological environment of the classic copper-molybdenum porphyry deposit of the Gaspé Copper Mountain Mine are numerous, including the calcareous mudstone injected by felsic porphyry dykes.

2026 Exploration Program: In late August 2026, an airborne geophysical program was completed consisting of 1,405 line-kilometres of high-resolution helicopter-borne magnetic and VLF-EM surveys. Preliminary interpretation of the survey data has outlined two intense circular magnetic anomalies, confirmed as being associated with intrusive bodies injected in calcareous mudstone and therefore high-priority exploration targets for skarn-related mineralization.
Secondary exploration targets are manifest as faint linear anomalies perpendicular to the regional tectonic fabric, thought to represent potential secant dykes or fractures.
Immediate ground follow-up of the anomalies was conducted by a 7-person prospecting and geological team for 2-weeks. About
IOS Geosciences, a well-established geological consulting group from Saguenay, Québec, has been mandated to execute the field program.
