Anticline Lake Zone
One of the district's earliest recognized Cu-Ni-PGE occurrences — now ready for modern exploration
The Anticline Lake area was among the first mineralized zones documented in the district, identified during J.A. Retty's 1945 aerial reconnaissance when multiple gossans were spotted in the Anticline-Hyland Lake area. It has since been the subject of intermittent reconnaissance work by successive operators, but has never received the systematic, modern exploration it warrants.
Historical Context
The Anticline Lake area was first flagged during Retty's landmark 1945 reconnaissance flight, which produced the region's first sketch map of gossan occurrences. Hollinger followed up in the 1950s with regional mapping and an airborne geophysical survey, and later drilled widely spaced reconnaissance holes across several showings in the broader area — though notably, those early samples were never assayed for platinum group elements.
The zone sits within the same favourable geological sequence that hosts the Blue Lake deposit: ultramafic intrusive units along the margin of the Superior Craton, where deep crustal faults channelled magma-bearing conduits capable of forming Cu-Ni-PGE mineralization.

Exploration Potential
Despite being recognized for over eighty years, the Anticline Lake zone has never been tested with modern high-resolution airborne EM, detailed structural mapping, or systematic geochemical sampling. CUPANI's 2025 exploration program — which covered 363 km² with a state-of-the-art TargetEM26 airborne survey and deployed three mapping teams across the district — generated new geological data and interpretations that apply directly to this zone.
The combination of known surface mineralization, favorable host geology, and significant untested strike length makes Anticline Lake a priority area for follow-up ground geophysics and potential drill targeting in upcoming programs.
Next Steps
- • Integration of 2025 airborne geophysical data with historical geological observations
- • Targeted ground-based geophysical surveys planned for summer-fall 2026
- • Refinement of drill targets based on combined datasets
