Located in Okanogan County, north-central Washington, the Mazama copper project is a near surface, bulk-tonnage, copper deposit with an historic copper resource of 149 million tons grading 0.36% copper or approximately 1 billion lbs of copper.
The Mazama copper deposit was extensively drilled from 1970 to 1974 by Inspiration Development and then Quintana Minerals Corp., who together drilled 23 diamond drill holes and 47 percussion holes. The project was shelved due to low copper prices at that time.
The Mazama Project is situated on the southern extension of the prolific Quesnel Trough Copper Belt that runs through central BC into northern Washington. The Quesnel Trough is recognized as one of the largest copper belts in the world, trending for over 2000 kilometers. It currently hosts 8 producing copper mines and numerous other copper deposits.
The regional terrain in the Mazama area is low rolling hills with some pine and aspen forest. Road access is excellent and power and water are located nearby. The town of Winthrop is located 13 miles to the southeast of the Mazama Project and the city of Seattle is 110 miles to the west and the city of Vancouver 150 miles to the northwest. This allows for cost-effective exploration and development due to its non-remote location.
Blue River Resources Ltd acquired an option to earn a 100% interest in the Mazama Project in February 2013. The Company’s near-term exploration plans include a property-wide geophysical (magnetic) survey and a detailed surface mapping and sampling program. Surface sampling in the Flag Mountain zone is a high priority as a 60 ton bulk sample grading 0.10 oz / ton gold was reportedly mined from this area in 1918.
Blue River’s exploration program focus is to develop drill targets to confirm and expand the historic copper resource of 1 billion lbs of copper.
