Atlas (Au-Zn-Ag-Cu)

Localisation

  • 100% Eureka, acquired by project generation
  • 89 claims, 4,870.49 ha
  • 50 km east from Matagami
  • Cree communities of Waswanipi (Category III lands), Eeyou Istchee James-Bay territory
  • Year-round access via the Route 1055

Geological Context

Favourable context: Volcanogenic massive sulphides (Au-Zn-Ag-Cu VMS)

  • Calc-alkaline intermediate to felsic volcaniclastic (tuff) sequence in contact with sedimentary rocks
  • The northern and southern contacts of the sedimentary basin cut the volcaniclastic units (possible faults)
  • Little drilling in the area
  • The same volcaniclastic units host the Indice Principale Olga Zone (Au-Ag-Cu) deposit

Observed metallotects related to the geological model

  • Volcanic sequence similar to the Bousquet Formation (LaRonde mine: facies and geochemical affinity)
  • Aluminous-type alteration similar to the Doyon-Bousquet-LaRonde district
  • Contact between volcanic sequence and sedimentary rocks; volcanic hiatus, favourable VMS setting
  • Similar context to the Indice principale, Olga Zone deposit
  • Presence of favourability targets (MERN) for VMS
  • Gold values in the heavy mineral concentrate of till
  • Concentration of gold grains in till
