Klondike Project, COLORADO

Copper Exploration Alliance with Cloudbreak Discovery


Klondike Project Highlights:

Klondike Property Location Map

  • Road accessible 843 hectare property covering Paradox basin sedimentary package in San Miguel County, Colorado
  • Favourable stratigraphy known to host sediment-hosted copper deposits in the emerging Paradox Copper Belt
  • No copper exploration since the 1960s in the area
  • Exploring for additional deposits similar to the operating Lisbon Valley Mine, 50 km to the northwest

The Klondike project is located approximately 25 km south of Naturita, Colorado. This property lies within the Paradox Copper Belt, which includes the producing Lisbon Valley Copper Mine. There are numerous historical copper occurrences that have been identified throughout the district, however, many of these have not been explored using modern exploration techniques.

At Klondike, documented copper exploration ceased in the 1960s with subsequent exploration targeting uranium during the 1970s. Previous workers reported high-grade copper mineralization highlighted by results of 6.3% copper and 23.3 g/t silver in outcrop. In addition to its high-grade potential, disseminated copper-silver mineralization has been observed which may be amenable to modern open pit mining with Solvent Extraction Electro Winning (SXEW) processing similar to the Lisbon Valley Mine. Sedimentary-hosted copper deposits are an important contributor to world copper production, accounting for more than 20% of the world’s copper supply annually.

Klondike is located at the southeast end of a gypsum salt anticline in a similar structural setting as Lisbon Valley. Copper mineralization occurs in bleached and altered, porous and permeable, sandstone units adjacent to small graben-bounding normal faults. Copper mineralization in outcrop includes malachite, azurite, chalcocite and black copper oxides.


Surface sampling of mineralized outcrops along the graben faults has yielded assay results up to 6.3% copper and 23.3 g/t silver. Eleven of 15 samples reported from a limited historical prospecting and mapping program returned assays ranging from 0.12 to 6.3% copper and below detection to 85.4 g/t silver. Additionally, disseminated copper-silver mineralization has also been identified in outcropping sandstones of Jurassic and Permian age. Both styles of mineralization will be investigated in upcoming work programs with the goal of refining drill targets in these units. Initial work will include detailed geological mapping, soil and rock sampling, and geophysics.

The project is road accessible year-round, traveling 2 km of gravel road from paved highway. The project is comprised of 72 mining claims managed by the BLM, in addition to an Exploration Permit with an exclusive right to a State Lease from the State of Colorado.
