Geology
A Rare Geological Opportunity in Canada
The Casino Deposit
The Casino deposit is a porphyry copper-gold-molybdenum-silver system located in Yukon’s Dawson Range—part of the Tintina Gold Belt in central Yukon. These deposits are formed when mineral-rich fluids rise through fractures in the Earth’s crust, depositing metals as they cool.
This process created one of Canada’s largest undeveloped copper-gold resources, with distinct zones of enriched copper mineralization.
The Geologic Setting
- The deposit is centred on the 70-million-year-old Patton Porphyry, an east-west trending body of rock
- This porphyry intrudes older rocks from the Dawson Range Batholith as well as Paleozoic schists and gneisses of the Yukon-Tanana Terrane
- The intrusion caused brecciation (rock fragmentation) at its northern, southern, and eastern margins, forming rich mineralized zones
Mineralization & Structure
1.
Leached Cap
Mineralization: Weathered zone with oxidized sulphide minerals
Metals: Copper removed; residual gold remains
Notes: Surface weathering from historical leaching processes
2.
Supergene Enrichment Zone
Thickness: Up to 100 m thick
Mineralization: Secondary copper sulphides (higher-grade copper)
Metals: Enriched copper concentration
Notes: Rare in Canada; preserved due to minimal glacial erosion (more common in Chile and U.S. Southwest)
3.
Hypogene Zone
Thickness: Extends more than 600 m below surface
Mineralization: Primary sulphide zone
Metals: Pyrite, chalcopyrite (copper), and molybdenite (molybdenum)
Notes: Represents the long-term production base of the Project
What Makes the Casino Project Unique?
- It’s a large deposit. The mineralized area stretches about 1.8 km long and 1 km wide.
- The rich copper layer is well-preserved. Unlike many other sites, the high-grade enrichment zone is intact.
- The minerals go deep. Valuable metals are found hundreds of metres below the surface.
- It contains several important metals. The deposit includes copper, gold, molybdenum, and silver, critical for Canada’s economy and clean energy future.
