FIN Resources Confirms Extensive Sulphide Mineralisation at Cabin Lake Arrow Prospect

Significant Sulphide Zones Confirmed at Arrow

FIN Resources Limited (ASX:FIN) has reinforced its geological model at the Cabin Lake Gold Project in Canada’s Northwest Territories, confirming significant sulphide mineralisation across three diamond drillholes at the Arrow Prospect. The combined sulphide-bearing banded iron formation (BIF) intervals total approximately 114 metres based on geological logging, with the broadest zone extending around 63 metres in drillhole CL-26-003. Visual logging indicates pyrite dominates the sulphide assemblage, accompanied by minor pyrrhotite, with sulphide intensity increasing at depth, including strong veining.

These results build on the maiden drillhole CL-26-001, which intersected a 38-metre sulphide zone and was previously reported in March 2026. The consistency of sulphide mineralisation across all three holes underscores the potential scale and continuity of the mineralised corridor. However, no assay results are available yet for the recent holes, leaving exact gold grades unconfirmed.

Encouraging Early Signs at Beaver Prospect and Ongoing Drilling

Beyond Arrow, the company has initiated drilling at the Beaver Prospect with drillhole CL-26-004 completed and logging underway, while CL-26-005 is in progress targeting the Andrew South Prospect. Early observations at Beaver are promising, with sulphide mineralisation noted early in the core, suggesting continuity of the system along strike. This expansion reflects FIN’s strategy to systematically test multiple targets within the ~15-kilometre Bugow Iron Formation corridor.

Integrated Geophysical Program Enhances Exploration

FIN is complementing its drilling with a comprehensive geophysical program, including a ground magnetic survey that is approximately two-thirds complete, downhole induced polarisation (IP) surveys on four drillholes, and a newly commenced surface dipole-dipole IP survey. These geophysical techniques aim to map sulphide distribution and structural controls beyond drill intercepts, addressing complexities in the folded and structurally controlled BIF host rock.

The integration of magnetic and IP datasets with geological logging is designed to improve the interpretation of sulphide mineralisation continuity both laterally and at depth. This approach is critical given the early-stage nature of the drilling and the structural complexity of the system. The company plans to use these insights to refine drill targeting ahead of a broader summer drilling campaign.

Context and Next Steps

FIN’s ongoing program follows the successful initial drillhole at Cabin Lake, which intersected a broad sulphide zone consistent with historical data and the company’s model, as detailed in their recent broad sulphide zone in maiden drill. The current winter drilling phase leverages lake-based access to expedite data collection, with plans to extend geophysical coverage and drilling through the summer season.

Upcoming milestones include completing the remaining ground magnetics, interpreting downhole IP results, advancing the surface IP survey, and receiving assay results from the initial holes. These data will collectively inform the geological model and support ongoing exploration along the mineralised corridor.

FIN’s Cabin Lake project benefits from a Tier-1 jurisdiction, proximity to historical gold mines, and established community engagement with the Tłı̨chǫ Government, factors that underpin the company’s exploration progress and future potential.
