Admiral (Au)

À propos du projet Admiral

Le projet Admiral fait partie des "Trois A", 3 projets détenus à 100% par Tarku dans la région de Matagami (Admiral, Apollo et Atlas) totalisant 248 titres miniers centrés sur l'extension orientale de la faille régionale de Sunday Lake incluant le cisaillement ductile de la Rivière Waswanipi (RWSZ). Le projet Admiral est situé à l'ouest du lac Olga et comprend 78 claims (4 334 ha) centrés sur la zone de cisaillement ductile de la rivière Waswanipi.

Le projet a été acquis par "Génération de projet" sur la base de plusieurs points d'intérêts géologiques. Ceux-ci incluent les informations fournies par la cartographie la plus récente de la région et les résultats historiques qui ont identifié des grains d'or dans des dépôts glaciaires.

Atlas présente de fortes similitudes de minéralisation aurifère avec le contexte géologique de la mine de Detour Lake et du camp minier de Kirkland Lake. La direction de Tarku croit que le potentiel aurifère du secteur Matagami a été sous-évalué et utilise aujourd'hui des modèles géologiques et des techniques d'exploration modernes pour faciliter la découverte de minéralisation aurifère.

Geological Context

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)

Local Geophysics

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.

Exploration Results

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

Exploration programs

The Admiral Project has new drill targets. Tarku is looking for partners to advance the project to the next stage.
