Drilling Success at Target K
FMR Resources Limited, in joint venture with Southern Hemisphere Mining, has announced the completion of drillhole 26LHDD072 at Target K within the Llahuin Project in Chile. The hole reached a depth of 1,038.2 metres and intersected multiple broad mineralised porphyry intrusive phases, including andesitic porphyry, diorite, granodiorite porphyry, and diorite porphyry. These rock types are typical of porphyry copper systems and were accompanied by visible copper and molybdenite sulphides, confirming proximity to the mineralised intrusive footprint.
Geological and Structural Insights
The drilling revealed zones of stockwork veining, pervasive silicification, and breccia development, all consistent with porphyry-style magmatic phases. Visible chalcopyrite and molybdenite were observed within quartz-sulphide veinlets and disseminations. Structural data from this and previous holes indicate a shift in vein orientation, suggesting increasing complexity closer to the fluid source. This has provided a clear vector pointing south and east of the current drillhole towards the interpreted core of the mineralised porphyry system.
Geophysical Data Integration
Integration of geological observations with surface and downhole geophysical datasets, including magnetotelluric and induced polarisation surveys, suggests that the prominent MT anomaly previously identified is likely mapping a pyrite-rich peripheral shell rather than the copper-molybdenum-rich core. This interpretation has guided the decision to terminate the current drillhole before intersecting the centre of the anomaly and to plan subsequent drilling to the south and east to test the refined model.
Next Steps in Exploration
FMR Resources is currently processing downhole geophysical data from Target K and integrating it with existing data from Targets A and C. The company plans to refine the three-dimensional geological model of the porphyry system and design the next drillhole to test the interpreted mineralised source. Assay results from 26LHDD072 are awaited to quantify the grades of copper, molybdenum, and associated metals. The ongoing work aims to systematically vector towards the core of this extensive copper-gold-molybdenum system.
Context within the Llahuin Project
The Southern Porphyry target lies within a six-kilometre mineralised corridor at Llahuin, which hosts multiple copper-gold-molybdenum porphyry centres. Previous drilling and surface mapping have identified alteration and mineralisation typical of a telescoped porphyry system, with epithermal-style veining preserved above a deeper porphyry core. The current drilling campaign builds on this foundation, aiming to delineate and expand the resource base within this highly prospective region of Chile, the world’s leading copper producer.
Bottom Line?
As FMR Resources zeroes in on the porphyry core, upcoming assays and drill plans will be pivotal for the Llahuin Project’s next phase.
Questions in the middle?
- What grades will the pending assays from drillhole 26LHDD072 reveal for copper and molybdenum?
- How will the refined structural and geophysical model influence the scale and scope of future drilling?
- Could the interpreted pyrite-rich shell impact the economic viability or processing strategy of the deposit?
