The White River copper deposit in southwestern Yukon is described in this geological report. It details the native copper and copper sulfide mineralization within Upper Triassic Nikolai Greenstone, including mineral associations and postulated two-stage formation. The report was published by the Government of Yukon and last updated on 2026-04-17.
Use Cases
- Identify native copper mineralization patterns based on descriptions of fractures, amygdules, and crackle zones.
- Study copper sulfide formation based on descriptions of Stage II mineralization in crosscutting structures.
- Analyze the relationship between metamorphism and copper deposition based on the described prehnite-pumpellyite facies minerals.
- Compare geological timelines based on the postulated 120 million-year age for the metamorphic event.
Strengths
- Detailed mineralogical description lists specific ore minerals including native copper, chalcocite, bornite, chalcopyrite, pyrite, digenite, covellite, cuprite, and native silver.
- Provides a geological timeline, stating Stage II mineralization post-dated host rock formation by at least 80 million years.
- Identifies specific metamorphic facies minerals (chlorite, epidote, prehnite, pumpellyite, calcite analcite, apophyllite) associated with the mineralizing process.
Limitations
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
- Data may reflect geographic bias inherent to open_canada, focusing on a single deposit in Yukon.
