Brightstar Resources has intersected 305m at 2.66 grams per tonne (g/t) gold at its Two Mile Hill deposit in Western Australia, delivering its largest-ever Sandstone drilling result on a grade-times-width basis.
The intersection, returned from 503m in diamond hole TMHDD26005, included several high-grade zones, including 4.1m at 26.1g/t gold, 5.5m at 25.2g/t, and 4m at 60.8g/t.
The latter contained a narrower interval of 0.9m at 241g/t gold, highlighting the high-grade veins within the broader mineralised tonalite.
Brightstar managing director Alex Rovira said the results demonstrated the deposit’s potential to expand beyond its existing resource.
“The latest Two Mile Hill results demonstrate the vast scale potential that the deposit holds. This deep diamond drilling was designed to define the extent of the Shirvington Zone and assess the grade continuity at depth,” Rovira said.
“What we have seen produced are wide, bulk intercepts of impressive gold grades. The standout result from these latest assays is our biggest-ever intercept at Sandstone, totalling over 800 gram-metres.”
A second hole, TMHDD26004, returned 80m at 2.64g/t gold from 499m, including 1m at 160g/t, alongside a separate 240m intersection grading 1.16g/t gold from 601m.
Both holes extended mineralisation materially below the current mineral resource estimate (MRE), reinforcing the potential for further growth at depth.
The results follow earlier deep drilling at Two Mile Hill, which returned 305m at 1.33g/t gold from 584m, including 173m at 1.42g/t beneath the existing resource.
That drilling also confirmed the host tonalite extended beyond 400m in width, strengthening Brightstar’s interpretation of a large mineralised system.
Two Mile Hill-Shillington’s resource also nearly doubled in September to 1.45 million ounces, contributing to Sandstone’s broader 3.6-million-ounce inventory.
Meanwhile, Brightstar has commenced a further 6500m deep-drilling campaign, targeting extensions to the Shirvington Zone along strike and at depth.
“The drilling has produced classic Two Mile Hill-style mineralisation, defined by wide zones of lower-grade mineralised tonalite, punctuated by high-grade veins rich in visible gold,” Rovira said.
“With the results from hole TMHDD26006 still pending, we look forward to receiving the final assays from the program.”
The latest drilling complements Brightstar’s recent identification of 11 exploration targets across the Two Mile Hill–Bull Oak corridor, and the miner is continuing work towards an updated Two Mile Hill resource estimate and Sandstone pre-feasibility study, both previously targeted for completion during the December quarter.
