Chalice Mining Limited (ASX:CHN)

Chalice Mining Limited announced initial results from first-pass reverse circulation drilling at the Deep Blue target within its Goomalling Copper Project in Western Australia, where 16 holes for 1,874m across three wide-spaced drill lines intersected broad, shallow, low-grade copper-silver-gold mineralisation over approximately 1.2km of strike, confirming a large-scale mineralised system that remains open and supporting the emergence of a newly recognised approximately 30km copper belt now termed the Goomalling Copper Project; key reported results included 21m at 0.18% Cu, 0.67g/t Ag and 0.03g/t Au from 50m in DBRC004, including 4m at 0.41% Cu and 2m at 0.47% Cu, and 9m at 0.21% Cu, 0.86g/t Ag and 0.05g/t Au from 180m in DBRC005, with widespread disseminated and fracture-controlled chalcopyrite observed across broader intervals and comparable mineralisation previously identified at the nearby Kann target, suggesting district-scale potential within the Corrigin Tectonic Zone; Chalice said the mineralisation style and tenor are broadly comparable to the nearby Caravel Copper Project, although genesis remains unconfirmed, and noted that previously reported high-grade REE rock chips exceeding 15% TREO were not explained by this drilling but may relate to ENE-trending structures that remain under-tested, prompting planned follow-up work including structural interpretation, IP surveying, expanded and infill soil sampling, and further RC drilling in Q4 CY26 after the cropping season, while the project currently comprises a 70%-earning joint venture with Northam Resources plus 100%-owned licences covering about 1,200km2.
