Chalice Mining Limited has intersected broad zones of low-grade copper, silver, and gold during its maiden reverse circulation drilling program at the Deep Blue target within the Goomalling Copper Project in Western Australia.

The reconnaissance program comprised 16 holes totaling 1,874 metres across three drill lines spaced approximately 600 metres apart. Drilling confirmed an extensive mineralised system spanning an approximate 1.2-kilometre strike length that remains open along strike. Key results include hole DBRC004, which returned 21 metres at 0.18% copper, 0.67 grams per tonne silver, and 0.03 grams per tonne gold from 50 metres downhole. This included a higher-grade interval of 4 metres at 0.41% copper, 1.20 grams per tonne silver, and 0.07 grams per tonne gold from 50 metres, and 2 metres at 0.47% copper, 2.38 grams per tonne silver, and 0.04 grams per tonne gold from 67 metres. Additionally, hole DBRC005 intersected 9 metres at 0.21% copper, 0.86 grams per tonne silver, and 0.05 grams per tonne gold from 180 metres, including 1 metre at 0.27% copper, 1.56 grams per tonne silver, and 0.05 grams per tonne gold.

Chalice initially defined the Deep Blue target earlier in 2026 through rock chip sampling and ground geophysics located approximately 15 kilometres south-east of the Caravel Copper Project near Goomalling in Western Australia. The company has materially expanded its regional tenure position to cover a newly recognized approximately 30-kilometre strike length copper belt, supported by seven new mineral tenements staked near the project between June and July 2026.

The broader mineralisation style shares similarities in grade tenor and metal association with the Caravel Copper Project. Chalice plans to commence expanded soil sampling, targeted induced polarization geophysics, and follow-up reverse circulation drilling at the Goomalling Copper Project in the fourth quarter of 2026 following the cropping season.
