SnapshotA Feasibility Study was completed in May 2024, which shows potential for Troilus to rank among the largest gold producers in Canada.

As a result of the previous operation, the Troilus property already has well established infrastructure, including an extensive network of well-maintained all-weather access roads, a 50MW substation and +60 kms of high-tension power lines maintained by Hydro-Quebec, a permitted tailings facility, and operating water treatment plants.

August 13, 2024, Troilus Gold Corp. is pleased to report the start of dewatering at the J4 pit, expected to take 6 months, and the Z87 pit, expected to take 18 months. The successful completion of the Environmental Impact Assessment and the installation of necessary equipment and infrastructure have showcased the company's capability to navigate the regulatory and stakeholder requirements, enabling the advancement of the Troilus Project through the permitting process.

Summary:

The mineralized zones of the Troilus Project are known as Archean porphyry-type deposits. Other interpretations of the deposits include superimposed, structurally controlled, “orogenic” gold deposits.

The Troilus Gold deposit lies within the eastern segment of the Frotêt-Evans Greenstone Belt (FEGB), in the Opatica Subprovince of the Superior Province in Québec. The FEGB is largely dominated by tholeiitic basalts and magnesian basalts that occur in association with felsic and intermediate calcalkaline pyroclastic rocks, lava flows, and local ultramafic layers. Syn- to post-deformational gabbroic to monzogranitic plutonic rocks occur throughout the greenstone belt.

The main mineralized zones at the Property occur around the margins of the Troilus Diorite, and comprise the Z87 Zone, J Zone, X22 Zone, and the SW Zone. Other significant targets near these zones include: the northern continuity of the J Zone, the Allongé Zone; the northeastern continuity of the SW Zone, the Gap Zone.

Troilus is primarily an Au-Cu deposit, but contains minor amounts of Ag, Zn and Pb, as well as traces of Bi, Te, and Mo. Gold-copper mineralization at the Troilus deposit comprises two distinct styles, disseminated and vein-hosted. Gold mineralization is spatially correlated with the presence of sulphides, even though the sulphide content does not directly correlate with gold and copper grade. The matrix of the diorite breccia, the diorite and the felsic dikes represent the main host rocks for the mineralized intervals.
