Latest News on the Project
The Admiral project is part of the “Three A’s”, 3 projects wholly owned by Tarku in the Matagami area (Admiral, Apollo and Atlas) totaling 248 mining titles centered on the Eastern extension of the Sunday Lake regional fault including ductile shear of the Waswanipi River (RWSZ). The Admiral project is located west of Lake Olga and consists of 78 claims (4,334 ha) centred on the Rivière Waswanipi ductile shear zone.
The project has been acquired by “Project Generation” based on several points of geological interests. These include information provided by the most recent mapping of the area and historical results that identified gold grains in glacial deposits.
Atlas has strong gold mineralization similarities with the geological context found at the Detour Lake Mine and the Kirkland Lake Mining Camp, and Tarku’s management believes that the gold potential of the Matagami sector has been undervalued and uses today modern geological models and exploration techniques to aid in the discovery of gold mineralization.
The Admiral project is located west of Lake Olga and consists of 97 claims (50.6 km2 ) overlying the convergence of the Rivière Waswanipi (RWSZ) and Lac Olga (LOSZ) shear zones. The LOSZ contains the Lac Olga Ouest gold showing (5.9 g/t Au, grab sample, GM 49140) and Newmont’s high-grade deposit Indice Principal zone Olga located 10 km southeast of Admiral (14.75 g/t Au, 1.14% Cu and 10.3 g/t Ag over 1.50 m, GM 50632).
The Rivière Waswanipi regional structure is characterized by the presence of alkaline rocks, polygenic conglomerates (Timiskaming type) and porphyry intrusions bearing anomalous gold values on the order of hundreds of parts per billion (GM 52712). This corridor, altered to carbonate-hematite-magnetite, contains the Rivière Waswanipi gold showing (2.36 g/t Au over 1 m; GM 51193) hosted in a porphyritic dyke and tuffs altered to pyrite-fuchsite as well as several porphyry intrusions bearing anomalous gold values on the order of 0.1 to 0.9 g/t Au over 0.6 to 5 m (GM 52712).
Previous Exploration Programs
In May 2018, Tarku completed a 294 line-km high-resolution helicopter-borne magnetic survey over the entire Admiral Project. Flight lines were surveyed at a 100-metre spacing and was conducted by Prospectair (Gatineau, Quebec) and Dynamic Discovery Geoscience (Ottawa, Ontario) to improve current interpretations of the mineralized systems and identify new gold targets.
The survey demonstrated a previously unrecognised structural complexity and revealed the presence of numerous secondary structures and major folds in a 1 to 1.5 km wide corridor bordered to the north and south by the two major shears RWSZ and LOSZ (see FIGURE 1). The interpreted data identifies 6 priority drilling targets defined by the intersection of structures, the axial planes of folds, historical electromagnetic Input anomalies and by a non-magnetic signal or low magnetic features which may represent silica-tourmaline alteration zones as observed at the Indice Principal zone Olga deposit.
In winter 2019, Tarku conducted a small drill program. Despite the fact that the samples did not return any economic gold results, the 5 drill holes demonstrated the presence of numerous elements consistent with the orogenic gold exploration model associated with alkaline rocks and porphyry intrusions (syenite-associated type). A total of 796 meters was completed in 5 drill holes. Most of the holes intersected brittle-ductile faults zones injected by "syenitic and monzonitic" dykes. Albite-iron carbonate-hematite alterations with tourmaline-quartz-pyrite veinlets were notably observed in drill hole AD-19-03. The results allow the correlation of the anomalous presence of gold traces in association with syenitic dykes with albite-iron carbonate-hematite alteration.
