Maiden Resource Estimate

In 2021, QC Copper completed a 20,000-metre drill program including twin holes and infill drilling.  A Maiden Resource Estimate was released in September 2021.

Highlights of Maiden Resource Estimate:

  • 82% of resource in M&I category: High confidence, pit constrained resource
  • 1.58Bn CuEq lbs @ 0.88% CuEq in M&I category & 345.8M CuEq lbs @ 0.73% CuEq Inferred
  • High grade Starter Pit of 1.26% CuEq offering prospect of accelerated payback & enhanced economics
  • Average grade is ~4X the cut-off, which is 0.2% CuEq @ US$3.50/lb Cu, US$1,650/oz Au

New Robust Open Pit Copper-Gold Deposit - Maiden Resource Information

History of Opemiska

QC Copper acquired the Springer and Perry properties from Ex-In, who acquired the properties in 1993 and digitized the abundance of data from Falconbridge operations. Falconbridge, between 1953 and 1991, previously mined both the Springer and Perry mines. Together, they produced 23 million tonnes grading 2.4% copper and 0.3 g/t gold. In 2021 QC Copper has completed a 20,000-metre drill program and released a Maiden National Instrument 43-101 mineral resource estimate of 81.7M tonnes @ 0.88% CuEq of M&I Mineral Resources and 21.3M tonnes @ 0.73% CuEq of Inferred Mineral Resources.  

The company plans to undertake another drill program to further expand its resource and convert additional copper and gold into the M&I category.  

Location and Infrastructure

World-class jurisdiction in Chapais-Chibougamau, Quebec. Quebec offers favourable flow through tax incentives, straightforward permitting and approvals processing, and Quebec’s “Plan Nord” mandated to mining to develop natural resource extraction. The Property is easily accessible via gravel roads, logging roads and ATV trails connected to Chapais-Chibougamau. The region is served by a regional airport, located between Chibougamau and Chapais and two other airports located in Val-d’Or and Rouyn-Noranda, offering regular flights to Montréal, Toronto and the northeastern Canada (Nunavik and Nunavut). Local infrastructure is excellent with grid power at site. In Chapais-Chibougamau, railway access is prevalent with all required infrastructure to transport equipment, supplies and ore to and from local projects.

Regional Geology

In the Chapais-Chibougamau district, the geology is composed of late Archean volcanic and sedimentary rocks and economic mineralization consists of syn-volcanic VMS types deposits, syn-magmatic Fe-Ti-V deposits and porphyry environments and syn-deformational copper-gold vein systems associated with structures related to the main deformational event.


The initial resource is expected to continue growth through a follow-up 2022 drill program.  The following is Opemiska's Pit Constrained Model with a Vision to Expand the Current Pit

Next Steps: Ongoing Drilling to Expand Opemiska Mineral Resource & Explore New Targets

The 2022 Drilling Focus Remains on Expansion & Discovery and QC Copper has outlined multiple targets for expansion and discovery drilling this coming winter. These targets include:

  1. Resource growth is expected to come from infill within the resource envelope and extending known mineralization (i.e. Saddle zone, depth extensions and Eastern/Southern veins) 
  2. Gold-rich targets along the Gwillim fault including Robitaille, Cooke and new greenfield targets including Springer Lake and Sawmill-Levy VMS target
  3. Recently-acquired Roger project represents an additional satellite with growth potential

Given QC Copper's geologic model and knowledge of existing mineralization, there is an abundance of room to grow this Mineral Resource with further exploration and definition drilling.

Planning for the 2022 Winter Drill program is currently underway and an updated plan will be provided towards the end of 2021.  Drilling is expected to commence in Q1 2022.
