The site lies roughly 100km north of Port-Daniel and about the same distance south-east of Murdochville.
Vehicular access is possible via a network of forestry roads in the area.
According to the company, the newly acquired claims hold geological potential for porphyry copper-skarn mineralisation.
The land contains sedimentary rocks from the Ordovician Burnt Jam Brook and White Head formations, along with rocks from the Devonian Fortin Group and Cap Bon Ami Formation.
These units are segmented by the Grande-Rivière Fault and include porphyry dykes of the Lemieux intrusive suite.
The geological features are similar to those found at the Gaspé Copper Mountain Mine, which was a major copper producer.
While government records show no formal mineral occurrences on the Rocco Copper Prospect itself, historical reports reference malachite and other copper minerals on the property.
Seven copper mineralised occurrences have been logged in neighbouring holdings at the Lac McKay basaltic units, currently controlled by a third party.
The Gaspé Copper Mountain Mine, operated by Noranda Mines from 1955 to 1999, produced 150 million tonnes at 0.87% copper.
Osisko Metals is currently reassessing the site and, in April 2026, reported an updated resource of 1.83 billion tonnes (measured and indicated) grading 0.27% copper, 0.017% molybdenum and 1.57 grams per tonne silver, with additional inferred resources.
Cleghorn Minerals has hired Saguenay-based IOS Geosciences to carry out initial geological and geochemical data compilation, with plans for a field prospecting programme to begin in autumn 2026.
