Project Location & Access
The Rivière Doré property is located in Quebec, Canada, approximately 150 km between the towns of Mont-Laurier and Val-d’Or. The property spans 1032 claims covering an area of 600 square kilometers (60,000 ha), which benefits from year-round access via an extensive network of forestry access roads.
Regional Geology & Preliminary Exploration
The Rivière Doré property covers the base of an 80 kilometre-long newly discovered mafic layered intrusive complex.
Characteristics of Magmatic Ni-Cu sulphide deposits (layered intrusives), include:
- Layered intrusives provide the majority of the nickel produced in the world, and sources all of the world’s Platinum Group Elements
- Nickel grades are typically between 0.7 and 3.0 percent
- Copper grades are typically between 0.2 and 2 percent
- Occur as individual sulphide bodies associated with magmatic mafic and/or ultramafic bodies, or as groups of sulphide bodies associated with one or more related magmatic bodies in areas or belts up to ten, even hundreds of kilometres long (e.g. Sudbury, Thompson, Noril’sk-Talnakh, Kambalda, Raglan)
- Ore tonnages of individual deposits range from a few hundred thousand to a few tens of millions tons
- Consistently found in association with mafic and/or ultramafic magmatic bodies, but these parent bodies occur in diverse geological settings.
- Ores are characterized by an abundance of sulphide the common mineral assemblage dominated by pyrrhotite-pentlandite-chalcopyrite
The latest exploration activities on the property were completed in 2010. Highlights include:
- Discovery of Nickel-Copper bearing semi-massive sulfides on the property. Copper and nickel mineralization has been discovered in several outcrop and glacial boulders areas.
- Completion of detailed AeroTEM EM & Magnetics survey covering 3,800 line km. Subsequent interpretation of the data led to the identification of 42 distinct Conductive Target Zones (CTZ). The CTZ range from a few hundred meters to 7,000 meters in length and span the entire property area for a cumulative of 75.8 kilometers of conductive zones.
- Nine targets identified as high priority due to their close association with the recent surface discoveries and geochemical (till and bedrock) anomalies. The nine priority CTZs provide a cumulative of 24.8 kilometers of conductors with varying magnetic settings.
- First phase of sampling included a diamond saw channel cut, which averaged more than 1% copper over 6 meters.
2016 Exploration Program
Two drills are expected to be mobilized this year via pre-existing forestry access roads. Drilling will be focused on two high priority geophysical targets, Hopkins and Bruges Lake, which were identified in the 2010 Aerotem Survey. These correspond with both geophysical anomalies and outcrops/boulders with known mineralization. Based on drilling success, a larger follow-up drilling program will be designed for 2017.
