FMR Resources has reported promising assay results from its inaugural drilling at the Demoiselle prospect, revealing extensive copper-silver mineralisation and a new geological model to guide further exploration in Canada’s Fairfield Project.
- Maiden RC drilling intersects wide copper-silver zones up to 13.7m thick
- Mineralisation extends over 500m down dip and 250m along strike, open in all directions
- Structural fault control identified as key to copper deposition at redox boundary
- New geological model developed to target high-grade zones across Fairfield Project
- Company seeks government funding to support ongoing exploration activities
Initial Drilling Success at Demoiselle
FMR Resources Limited (ASX: FMR) has released assay results from its maiden reverse circulation (RC) drilling campaign at the Demoiselle prospect, part of the 100%-owned Fairfield Copper Project in New Brunswick, Canada. The drilling program, completed earlier this year, intersected encouraging wide zones of copper and silver mineralisation, including standout intervals such as 12.2 metres at 0.4% copper and 11.3 grams per tonne silver, and 13.7 metres at 0.3% copper with accompanying silver values.
These results mark a significant milestone for FMR, confirming the presence of sediment-hosted copper mineralisation over a substantial area. The mineralised zones extend over 500 metres down dip and 250 metres along strike, with thicknesses ranging from 2 to 14 metres, and remain open in all directions, suggesting considerable exploration upside.
Geological Insights and Structural Controls
The copper mineralisation is hosted within the basal conglomerates of the Boss Point formation, situated at a redox boundary between oxidised red beds and reduced grey beds containing coal fragments. This geological setting is critical, as the coal acts as a reductant facilitating copper deposition. The mineralisation is structurally controlled, occurring predominantly along a complex network of cross faults within the Dorchester fault system. These faults provide pathways for copper-rich basinal fluids to migrate and deposit copper minerals such as chalcocite and malachite near the unconformity.
FMR’s geological team has developed a conceptual mineralisation model based on these observations, highlighting the importance of structural complexity in localising higher-grade copper zones. This model will be instrumental in guiding future exploration efforts not only at Demoiselle but across the broader Fairfield Project.
Strategic Location in a Proven Copper Belt
The Fairfield Project lies within the prolific Appalachian Copper-Gold Belt, a region known for significant copper deposits including the nearby Dorchester sediment-hosted copper deposit. The proximity to such established mineralisation enhances the prospectivity of FMR’s tenure, which covers 93.6 square kilometres of highly prospective ground.
FMR’s exploration approach integrates modern geophysical techniques such as VLF-EM, magnetic, and hyperspectral surveys, which have delineated several fault-controlled target areas for follow-up drilling. These targets will be assessed alongside historical data to refine exploration priorities.
Next Steps and Funding Support
Building on the success at Demoiselle, FMR plans to advance exploration at the Dorchester North area within the Fairfield Project, alongside field programs at the Goshen Project. The company has applied for the New Brunswick Junior Mining Assistance Program grant, which could provide up to C$100,000 in government funding to support these activities.
FMR continues to evaluate complementary project acquisitions to diversify its portfolio, maintaining a strategic focus on battery and critical minerals exploration in Canada.
Bottom Line?
FMR’s maiden drilling at Demoiselle lays a solid foundation, but the true scale and grade of the Fairfield copper system await further definition.
Questions in the middle?
- How will upcoming drilling refine the geological model and confirm true widths of mineralisation?
- What impact could government funding have on accelerating exploration timelines?
- Could FMR’s exploration success at Fairfield attract strategic partnerships or acquisitions?
