Project Summary
A Gold-Copper Deposit with Significant Historic Resources
Location and Access
The Calida project is located approximately 24 miles south of Salmon, Idaho in Lemhi County. It is directly accessible by road.
The elevation is about 6600 feet. These claims are on Bureau of Land Management (BLM) land.
Geology
The Calida project is characterized by a series of intensely altered and mineralized shear zones ranging from 1.5 meters to over 30 meters in width and extending up to 4,267 meters in length.
These shear zones act as hydrothermal conduits for ore-bearing minerals, primarily hosting native gold, chalcopyrite, pyrite, chrysocolla, malachite, azurite, limonite, and goethite.
The mineralization primarily occurs as gold-bearing copper and silver minerals. The regional geology indicates that the shear zones formed through hydrothermal processes that facilitated the migration and deposition of these valuable minerals within the zones of crushing and shearing.
Exploration and Resources
The project has undergone extensive exploration over the past few decades. In 1983, 29 drill holes were completed, revealing significant intersections of four primary mineralized veins, two of which span the width of the property.
Key intersections include hole W-3 with 5.5 g/T Au, 232.8 g/T Ag, and 4.30% Cu over 132 feet, and hole CA-1 with 6.7 g/T Au, 231.4 g/T Ag, and 4.45% Cu over 30 feet. Additionally, trenching and sampling identified ten mineralized veins on the property.
In 2009, an independent resource calculation based on historical data defined a resource of 8,059,304 tons grading 0.168 oz/ton Au, 6.12 oz/ton Ag, and 2.86% Cu.
