The Toroparu Deposit, Main, and South East areas are representative of an Archean gold (±copper) intrusion related system (Kontak, Katz, & Dubé, 2012) (Katz, Kontak, Dubé, & McNicoll, 2015) (Mathieu, Crépon, & Kontak, 2020). It closely resembles other structurally controlled, mesothermal gold systems seen in Archean greenstone belts such as the Abitibi or the Yilgarn craton. It appears genetically similar to deposits such as Côté Gold, Lac Doré, Boddington and Las Cristinas. Deposits of this type are closely associated with intrusive suites with geochemical signatures of rocks derived from hybrid melts (high heavy rare earth element, abundance of intermediate units, low- to moderate water content) (Mathieu, Crépon, & Kontak, 2020). They include porphyry copper-gold, syenite-associated disseminated gold, and reduced gold-bismuth-tellurium-tungsten intrusion related deposits, as well as stockwork disseminated gold. It is thought that this could be a result of the overprinting of two different deposit types. The Sona Hill Deposit represents an orogenic lode gold deposit and is related to the gold ± copper system at the Toroparu Deposit.
Toroparu Deposit, Main, and SE Areas
The Toroparu Deposit mineralization is oriented in a west-northwest direction with cross-cutting eas-twest mineralized structures. The system corresponds to a 2.7 km long and 200 m to 40 m wide body and extends to over 400 m in depth. The mineralized body occurs along the northwestern boun ........
