FMR Resources has completed a deep diamond drillhole at Target L within its Chilean Llahuin Project, intersecting extensive mineralised porphyry and stockwork breccia zones with visible copper and molybdenite sulphides. The results confirm a significant porphyry system beneath volcanic cover, setting the stage for targeted Phase II drilling.
- Diamond drillhole 26LHDD073 reached 1,068m depth at Target L
- Multiple broad mineralised stockwork breccia and porphyry phases intersected
- Visible copper and molybdenite sulphides observed in quartz and anhydrite veins
- Phase I drilling exceeded planned 4,000m, totaling over 5,000m drilled
- Assay results pending, guiding Phase II drilling to target porphyry core
Exploration Milestone at Target L
FMR Resources Limited (ASX:FMR) has announced the completion of diamond drillhole 26LHDD073 at Target L, part of the Southern Porphyry target within the Llahuin Project Joint Venture in Chile. The drillhole reached a depth of 1,068 metres, revealing multiple broad zones of mineralised stockwork breccia and porphyry intrusions. Notably, visible copper and molybdenite sulphides were observed within quartz–sulphide and anhydrite veinlets, confirming the presence of a significant mineralised porphyry system beneath volcanic cover.
Geological and Structural Insights
The geological logging identified several intrusive phases including Andesitic Porphyry, Quartz-Diorite, and Granodiorite Porphyry, all associated with hydrothermal alteration typical of porphyry copper systems. Structural measurements indicate complex vein orientations that suggest proximity to the fluid source of mineralisation. These findings support the interpretation that drilling has intersected the edges of an elongate mineralised porphyry intrusive corridor, extending from previously drilled Targets K and C.
Phase I Drilling Exceeds Expectations
Originally planned for approximately 4,000 metres, the Phase I drilling program has surpassed expectations with over 5,000 metres completed. This extensive drilling campaign has delineated both a shallow epithermal mineralised system and a deeper, extensive porphyry system. The integration of geological, geochemical, and geophysical data is underway to refine the understanding of the system and to vector towards the mineralised core.
Next Steps and Market Implications
Assay results from all Phase I drillholes are anticipated in the June 2026 quarter, which will provide critical multi-element geochemical data to fingerprint alteration signatures and guide future drill targeting. FMR plans to design a Phase II drilling program focused on testing the core of the Southern Porphyry system, leveraging integrated datasets to prioritise targets. This progression marks a significant step in advancing the Llahuin Project’s potential as a major copper-gold-molybdenum porphyry deposit.
Robust Methodologies Underpinning Exploration
The announcement also details comprehensive sampling, logging, and assay protocols adhering to industry standards and the JORC Code. Independent audits and quality control measures ensure data reliability. Geophysical surveys including drone magnetics, induced polarisation, and magnetotelluric methods complement the drilling data, providing a multi-dimensional view of the mineralised system.
Bottom Line?
With assay results imminent, FMR Resources is poised to sharpen its focus on the mineralised core, potentially unlocking significant value in the Llahuin JV.
Questions in the middle?
- What will the multi-element assay results reveal about the grade and extent of mineralisation?
- How will Phase II drilling targets be prioritised based on integrated geological and geophysical data?
- What are the implications of these findings for the overall resource potential and timeline at Llahuin?
