Great Bear Confirms 200 Copper Gold Targets Across Canada’s Premier IOCG Province
Great Bear confirms 200-plus copper, gold and silver targets ahead of maiden field campaign
Independent mineral targeting consultant Resource Potentials has generated more than 200 high-priority exploration targets across Great Bear Exploration’s 2,800km²+ Great Bear Lake Project in Canada’s Northwest Territories. The targets focus on copper, gold, silver and Iron Oxide Copper-Gold (IOCG)-style mineralisation. With target selection now complete, the company has commenced field and geochemical sampling across the project area, moving toward drill-ready status for an early start next spring.
This marks a de-risking milestone ahead of the company’s maiden field programme. The systematic target generation sets up a high-conviction pipeline for the coming exploration season.

Why 200 targets matters for the exploration story
The target package represents the culmination of an independent review integrating historical and recent datasets across the project. Key elements include:
- Independent review by Resource Potentials (ResPot), a globally recognised mineral targeting consultancy specialising in IOCG and uranium systems.
- Integration of historical datasets with 2024 work by White Cliff Minerals Ltd, assimilating geological, geochemical and geophysical data.
- Strong correlation identified across all mineralisation within the Great Bear Magnetic Zone (GBMZ), including larger IOCG targets.
- Dome and collapsed caldera structures flagged as prime targets — the key focus for this season’s work.
- Several new areas identified with limited prior exploration, including a new southern target at Grouard Lake.
Rod McIllree, Executive Director
“We are now in the final stages of pre-mobilisation for our maiden field programme at Great Bear. The independent target generation work by Resource Potentials has given us a clear, high-conviction pipeline of copper, gold and silver targets across a project that has seen remarkably little modern exploration. The Great Bear Magmatic Zone is widely regarded as Canada’s premier IOCG province. Our focus over the coming weeks is to systematically test the highest-priority targets on the ground, integrate the forthcoming FALCON survey and advance the project to drill-ready status for an early start next spring. I will be on site for the commencement of the field programme. Shareholders can expect regular updates as results come to hand.”
What is an IOCG system?
Iron Oxide Copper-Gold (IOCG) systems are large-scale mineral systems formed by hot fluids depositing iron oxides alongside valuable metals. Key characteristics include:
- IOCG deposits form when super-heated underground water deposits iron oxides (rust-like minerals) alongside copper, gold, silver and uranium.
- The GBMZ hosts multiple deposit styles within the broader IOCG framework: IOCG, Iron Oxide-Apatite (IOA), polymetallic epithermal veins, skarn and uranium.
- World-class benchmark: Olympic Dam in South Australia is the world’s largest IOCG deposit, demonstrating the potential scale of these systems.
The geophysical tools deployed by Resource Potentials — magnetics, radiometrics, gravity and electromagnetics (EM) — are complementary targeting methods designed to “see” different parts of the IOCG system. Magnetic data maps magnetite-rich zones, radiometrics detect uranium and alteration signatures, gravity identifies dense hematite cores, and EM surveys locate conductive copper sulphide mineralisation.
A premier province with production history but overlooked copper-gold
The Great Bear Magmatic Zone is recognised by the Geological Survey of Canada as Canada’s premier IOCG province. The northern portion of the belt supported significant historical mining between the 1930s and 1980s, but exploration focused primarily on uranium and silver. Modern geological interpretation now recognises these historical workings as the upper expressions of much larger IOCG systems, with copper and gold potential largely overlooked.
| Metal | Approx. Historical Production |
|---|---|
| Uranium (U₃O₈) | 13.7 million pounds |
| Silver | 34.2 million ounces |
| Copper (with gold credits) | 11.4 million pounds |
Past producers in the district included Eldorado (Port Radium), Echo Bay, Contact Lake and Norex. While historical activity concentrated on high-grade vein systems, the IOCG model suggests deeper, larger-scale mineralisation may exist beneath these surface expressions.
The belt remains under-explored relative to its demonstrable metal endowment. Large areas are covered only by low-resolution historical geophysical data, and vast portions have seen limited systematic modern exploration outside the historical near-mine environs. The presence of established infrastructure corridors, winter road access potential and airstrips within the project area improves the practicality of exploring such a large metallogenic belt.

Next steps: FALCON survey and the path to drill-ready
The company is advancing the project through a staged workflow over the coming weeks and months:
- Field and geochemical sampling across all targets over the coming weeks.
- Xcalibur Smart Mapping mobilising the FALCON Airborne Gravity Gradiometer — a 300m line-spaced AGG survey over all three volcano complex target areas, also acquiring magnetic and radiometric data, planned for August 2026.
- Integration of FALCON results with field data to define direct drill targets.
- Advance the project to drill-ready status for an early start next spring.
- Ongoing engagement with First Nation representatives in Deline regarding current and future programmes and winter camp establishment.
The company expects to provide regular updates as field results and the FALCON survey data come to hand. The investment thesis centres on a large, under-explored, infrastructure-supported land package in a premier IOCG province now backed by a systematic, prioritised target pipeline. The coming months will determine which targets advance to drilling.
