Summary
- 25,000ha high-potential brownfield copper-moly-silver-gold project associated with the Midcontinent Rift (“MCR”) in Ontario, Canada, which until 2021 had never been fully consolidated
- Recent porphyry and breccia drill holes as well as past copper production from two mines suggest the potential for larger intrusion related copper mineralization
- The project benefits from its strategic proximity to substantial infrastructure
Location and Ownership
Location of the Copper Road Project in Ontario, Canada located in proximity to significant infrastructure
- 100% owned and located in an area with a rich mining history, 30km from Batchewana Bay and situated between Wawa, Sault Ste. Marie, Sudbury and Timmins in Ontario, Canada
- The project is intersected by numerous highways and roads including the Trans-Canada Highway (Highway 17), which crosses the westernmost portion and provides major road connection to the city of Sault Ste. Marie
- The project is located 90km from the Port of Sault St Marie, and 40km from the Montreal River, which includes four hydroelectric dams and generating stations
- The project is also ideally located in proximity to two copper smelters outside of Sudbury
Geology
- Situated within the Mamainse Point Formation of the Keweenawan Group within the Proterozoic Southern Province, on the eastern edge of the MCR
- The MCR is home to numerous past-producing and present deposits around Lake Superior, including the prolific native copper deposits of the Keweenawan Peninsula in the U.S., mined for more than 150 years
- Porphyry mineralization at Copper Road has been sourced to the same age range as the primary mineralizing event within the MCR1
- The Mamainse Point area has a long history of prospecting, exploration, and mining activity dating to the mid-1800’s with the production of copper, silver, and gold from the Coppercorp Mine from 1965 to 1972 and the Tribag Mine from 1965 to 1973, now known as the Copper Road Project
- The Coppercorp mine reportedly produced 1.02Mt at 1.16% Cu2 while the Tribag Mine had reported ore reserves of 600,000 tons at 2.2% Cu2 with reported copper extracted of 16,000t from over 1Mt of ore from 1967-19743
- Following closure of the mines, significant sections of the district were closed to staking by the Ontario Government
- As a result of this, and fragmented land ownership, the area has seen only sporadic mineral exploration since the 1970
Mineralization
Mineralization at the Copper Road Project
- Since 2017, an aggregate of approximately 4,250m of drilling was completed by the previous operator, Copper Road Resources Inc.
- Drilling was focused primarily on confirming and extending known mineral occurrences at the past producing Tribag Mine and then at the JR Zone (Jogran Porphyry), discovered by Phelps Dodge in the 1960s
- At the JR zone:
- Drilling successfully confirmed the continuity of the copper and molybdenum porphyry hosted mineralization over long intervals
- This mineralization also extends to the southwest into the mafic volcanics where it is associated with localized and discrete potassic alteration (magnetite and biotite) occurring as haloes adjacent to quartz-carbonate veinlets and as local patches in the mafic volcanics
- Select results include:
- At the Richards Breccia:
- Drilling successfully extended the breccia 50 to 60m vertically below the known mineralization, establishing the vertical extent of mineralization to 130m from surface
- The breccia remains open at depth and potentially to the northeast
- Select results include:
