Located in the Amos area of the Abitibi belt, the property is 100% owned by Cogitore, subject to a 50% back in right held by Inmet Mining Corporation, and is accessible via public and logging roads which run across the project area. The Castagnier project was acquired to cover an old VMS copper prospect which hosts encouraging copper zones grading up to 3.2% Cu and 0.7% Zn over 3.1m (part of 1.2% Cu over 12m).

In the early 1950's, a vertical shaft was sunk to a depth of 120m to further explore the mineralization at depth but records of the work are incomplete. The rhyolite host rocks are strongly altered (sericite-chlorite) over at least 2 kilometres. Although no VMS deposits have been mined in the area, the chemical signature of the rhyolites at Castagnier is typical of that found in highly prospective VMS mining camps of the Abitibi belt (e.g. Kidd Creek). Drilling done to date has confirmed the presence of favourable rocks but additional work will be needed to locate the possible extension of mineralization discovered in the immediate area of the exploration shaft.
