Diamond Drillhole 26LHDD072 Hits Multiple Mineralised Porphyry Phases to 1,038m
FMR Resources has intersected multiple broad mineralised porphyry phases with visible copper and molybdenite at Target K within its Llahuin Project JV in Chile, refining the search for the core mineralised source.
- Diamond drillhole 26LHDD072 completed to 1,038.2m depth
- Multiple porphyry intrusive phases with visible copper and molybdenite sulphides intersected
- Structural and geophysical data vector mineralisation south, east, and deeper
- MT anomaly likely maps pyrite-rich peripheral zone, not copper-molybdenum core
- Next drillhole planned to test refined porphyry source interpretation
Drilling Success at Target K
FMR Resources Limited (ASX:FMR) has announced the completion of diamond drillhole 26LHDD072 at its Southern Porphyry target within the Llahuin Project Joint Venture in Chile. The hole reached a depth of 1,038.2 metres and intersected multiple broad phases of mineralised porphyry intrusions, including andesitic porphyry, diorite, granodiorite porphyry, and diorite porphyry. Notably, visible copper and molybdenite sulphides were observed within quartz-sulphide veinlets and disseminations, confirming proximity to the mineralised intrusive footprint.
Refining the Geological Model
Structural measurements from this and previous drillholes reveal a change in vein orientations, interpreted as increasing complexity closer to the fluid source. This has provided a clear vector pointing south, east, and at depth from the current drill position. Integration of geological observations with surface and downhole geophysical data suggests that the prominent magnetotelluric (MT) anomaly is primarily responding to pyrite-rich peripheral mineralisation rather than the copper-molybdenum-rich core. This insight has been pivotal in refining the exploration model.
Implications for Future Drilling
Based on the integrated datasets, FMR is planning the next drillhole to test the interpreted porphyry source located south and east of Target K. The company’s managing director, Oliver Kiddie, emphasised that the recent drilling confirms they have intersected the outer mineralised zones of an extensive system and that the next phase will systematically vector toward the core mineralisation. Assay results from 26LHDD072 are pending, with further updates expected as the program progresses.
Context within the Llahuin Project
The Southern Porphyry target lies within a six-kilometre mineralised corridor that hosts multiple copper-gold-molybdenum porphyry centres. Surface mapping has identified alteration and epithermal veining typical of the upper levels of a porphyry system, while drilling has confirmed these features at depth. The system appears telescoped, with epithermal-style alteration preserved above a deeper porphyry core, underscoring the potential scale and complexity of the deposit.
Robust Exploration Methodology
FMR’s exploration approach combines detailed geological logging, petrography, multi-element geochemistry, and advanced geophysical surveys including magnetotelluric and induced polarisation methods. The company adheres to rigorous sampling and assay protocols consistent with JORC Code standards, ensuring data quality and reliability. This integrated methodology supports confident targeting and resource definition as drilling advances.
Bottom Line?
FMR’s latest drilling at Target K sharpens the focus on the mineralised core, setting the stage for a pivotal next phase of exploration.
Questions in the middle?
- What assay grades will confirm the economic potential of the mineralised zones intersected?
- How will the refined structural and geophysical vectors influence the scale and scope of upcoming drilling campaigns?
- Could the interpreted pyrite-rich shell around the core affect future resource modelling and valuation?
