Opinaca/Wildcat James Bay, Quebec

The Opinaca-Wildcat project is located at 320km (199 miles) north of the city of Matagami, in the James Bay territory, Quebec, Canada.

Map - Opinaca/Wildcat
Overview & History

The project consists of two properties: the Opinaca property in which Hecla Quebec is in the process of earning a 50% interest from Everton Resources and Azimut Exploration, and the 100% Hecla Quebec owned Wildcat property. Together these two properties comprise 669 claims covering an area of 34,972 hectares (135 sq. miles) near Goldcorp’s Eleonore Mine property, a world-class lode gold type deposit that contains over 9 Moz. at 0.18 oz/ton gold.


There is no NI 43-101 compliant resource reported on the Opinaca and Wildcat properties.


The Opinaca-Wildcat property straddles the contact between the metasedimentary Opinaca Subprovince and the volcano-plutonic La Grande Subprovince. The Opinaca Subprovince, to the North of the contact, is mainly composed of migmatized paragneiss and diatexites while the La Grande Subprovince, to the South, consists of bedded sediments, polygenic conglomerates and dioritic to granitic intrusions.

Two gold occurrences have been discovered in the Opinaca Subprovince and twelve have been discovered in the La Grande Subprovince of the Opinaca-Wildcat properties. Most of these gold occurrences are hosted in the sedimentary Low Formation, near the contact between the two Subprovinces and in close relationship with hydrothermal alteration zones. Gold mineralization is associated with quartz-tourmaline-arsenopyrite veins, quartz-feldspar-pyrite-pyrrhotite replacement zones and pyrite-pyrrhotite dissemination in calc-silicate metasomatism. The geological setting and the types of gold mineralization and alteration are similar to  those at the Roberto deposit of the Eleonore mine.

Since 2010, Hecla Quebec has carried out prospecting, mapping, outcrop stripping and channel sampling programs, ground and airborne MAG surveys, IP surveys, MMI soil and till surveys, and forty-four (44) diamond drill holes. This work helped to improve geological knowledge on known gold occurrences such as the Claude and Manuel targets, and led to the discovery of Autor, Mousson, Brad, Brad Jr., Emma and Panda gold occurrences.

Future Plans

Over the coming years, exploration fieldwork will focus on the Claude and Manuel targets and on the gold bearing showings between the Autor to Panda target areas. Future exploration work will also focus on underexplored areas of the Opinaca and Wildcat properties.
