FMR Resources confirms broad mineralised porphyry system in Chile

• Assays confirm broad copper–gold–molybdenum anomalism.
• Assays support geological interpretation of an extensive porphyry system.
• Integration of assays, petrography and multi-element geochemistry ongoing.

FMR Resources (ASX:FMR) has confirmed a geological interpretation of an extensive porphyry system with final assay results at the southern target within the Llahuin project joint venture in Chile.

Diamond drillhole 073 was designed to test structural, geological and geochemical vectors interpreted from previous drillholes 070, 071 and 072 and intersected multiple porphyry intrusive phases, broad zones of stockwork veining and pervasive hydrothermal alteration.

MD, Oliver Kiddie, said visible chalcopyrite and molybdenite were identified in quartz–sulphide, magnetite–sulphide, and anhydrite veinlets throughout the drillhole.

“The assays from target L validate the geological observations from drilling, confirming a broad mineralised porphyry system containing copper, molybdenum and gold anomalism associated with intrusive phases and stockwork breccia,” he said.

“Importantly, the geochemistry supports our interpretation that drilling to date has intersected the margins of an extensive porphyry system rather than the higher-grade core. Integration of the assays with structural, petrographic and geophysical datasets is continuing to refine vectors for Phase II drilling.”

FMR’s geological interpretation continues to indicate that existing drilling has intersected the edges of an elongate mineralised porphyry intrusive corridor. Structural measurements from target L demonstrate increasing vein complexity relative to earlier drilling, interpreted to reflect proximity to the porphyry fluid source.

Multi-element geochemistry, whole-rock geochemistry, and petrophysical and petrographic studies are continuing to refine vectors toward the interpreted higher-temperature copper– molybdenum core of the Southern Porphyry system.

Thin-section petrography of key lithologies and alteration assemblages is ongoing to characterise mineral relationships, alteration zoning and paragenesis, contributing to the reconstruction of porphyry system geometry. Geochemical analysis of anhydrite–pyrite samples also continues.

Multi-element geochemical data are being analysed in conjunction with petrographic observations to identify alteration patterns and elemental associations indicative of proximity to the porphyry core.

Integration of these datasets will assist in refining geochemical vectors and prioritising subsequent drill targeting within the southern porphyry system.

FMR is finalising plans for phase two drilling targeting the interpreted porphyry core.

FMR is steady at 37.5¢. Mkt cap $18.88M.
