Adding interest, the intersected zones in the first hole, which was drilled below 1970 results of 18.3m at 237g/t silver from a down-hole depth of 3m, are similar in character to textures observed at its 18Moz silver equivalent White Rock deposit.
Legacy Minerals’ (ASX:LGM) 4000m diamond drill program is aimed at assessing the gold-silver potential of the Mascotte workings, which strike for ~1.3km.
It will include gold assaying that was not carried out in historical drilling as recent surface sampling supported the view that historical silver results were potentially gold-bearing.
Meanwhile, first-pass drilling at the Battery prospect intersected wide zones of copper mineralisation associated with sheeted quartz-pyrrhotite-chalcopyrite veining.
The drilling, which tested for potential large-scale porphyry-related copper-gold mineralisation, returned a top assay of 52m at 0.15% Cu from 142m.
These early results confirm the prospectivity for a large-scale copper deposit and provide important information to vector towards potentially increased grades and width.
It also demonstrates the scale of copper mineralisation across Mt Carrington as this drilling is just ~7km from other copper results.
LGM expects to deliver the Mt Carrington scoping study in early March 2026 with an estimated additional two weeks added to the delivery timeframe to review technical aspects of the study.
Managing director Christopher Byrne said the company was very encouraged by the intersection of wide mineralised zones at the Battery prospect.
The result reinforces the belief that there’s widespread copper mineralisation in the Mt Carrington district with potential for a significant deposit.
“The widespread copper mineralisation seen in the results to date gives the company great encouragement to continue assessing the Project’s untested copper prospectivity and delineating higher-grade areas,” Byrne added.
“The technical team is assessing the results and their potential to vector towards thicker, higher-grade copper mineralisation at the Battery Prospect and across the district.”
He noted that gold-silver drilling targeting the 1.3km strike that had delivered previous high-grade silver results was progressing well.
“Drilling has intersected zones of very fine-grained sulphide mineralisation within veins and breccia, similar in character to mineralisation observed at the White Rock deposits, part of the significant Mt Carrington 115Moz silver equivalent resource,” he added.
The Battery prospect is characterised by a distinct magnetic feature indicative of an intrusive body associated with the interpreted Lunatic Field Porphyry high-resistivity core.
It is defined by a 3.4km diameter volcanic centre and a potential breccia pipe.
Wide zones of anomalous copper mineralisation associated with sheeted quartz-chalcopyrite-pyrrhotite veining and biotite alteration have been intercepted in three of the four drill holes.
White interpretation of the mineral system setting is ongoing, the width and consistency of mineralisation intersected to date is encouraging at this early stage of drilling.
Mascotte is defined by an area of significant historical workings where ground truthing has indicated the primary trend is ~1.3km in strike.
This also highlighted several potential parallel mineralised structures that were mined for silver and gold with elevated copper and zinc mineralisation.
Recently completed Airborne Mobile-MT identified a district conductivity lineament trending northeast and broadly associated with known mineralisation and historical workings.
This is consistent in the depth profile of the Mobile-MT data suggesting a major hydrothermal fluid pathway and provides encouragement for the potential scale and depth extent of mineralisation at the prospect.
Legacy Minerals is continuing drilling at Mascotte with a further six holes planned for completion with detailed geological logging and sampling ongoing.
Assays from the drilling are expected to start in Q1 2026.
