Trading Context

Chalice Mining shares were higher in Wednesday’s session, with data showing the stock up about 3.5% at around AUD 1.185 at roughly 2:40pm AEDT on 11 November 2026, on Volume of about 1.1 million shares. The rise followed a price-sensitive announcement lodged at 8:22am AEDT the same day, titled “Gonneville Project advances with pilot plant underway”.

Pilot Plant Activity

The ASX record confirms the headline and timing only. Earlier company material describes what a pilot plant at Gonneville is meant to achieve. A May 2026 article from, drawing on Chalice’s corporate presentation, said the company planned a continuous eight-week pilot plant run in the second half of 2026. The run was to use core from an 11-hole metallurgical drilling programme begun in April 2026, and was described as the final technical confirmation sought by potential financiers.

Gonneville Project

Chalice is a Western Australian explorer and developer. Its main asset is the 100%-owned Gonneville project, a palladium-nickel-copper deposit discovered in 2020 about 70 kilometres from Perth. A pre-feasibility study completed in December 2025 outlined a 23-year open-pit operation averaging about 220,000 ounces a year of 3E metals, with nickel, copper and cobalt by-products. Feasibility study work was reported to be under way.

Other Project Updates

Chalice has been active beyond Gonneville. On 2 November 2026 it lodged a price-sensitive release headed “High-grade copper-gold discovery at Tennant Creek, NT”, and the same day announced an investor webinar on its Warrego North project. It released its September 2026 Quarterly Report on 27 October and an updated corporate presentation on 5 November.

Financial Position

The ASX research data shows about 390 million shares on issue and a 52-week trading range of roughly AUD 0.87 to AUD 2.63, so the stock is trading well below its 12-month high. The ASX lists Chalice among the S&P/ASX 300 constituents.

Execution Considerations

Gonneville is not yet a funded or approved mine. Pilot results, the feasibility study, environmental approvals and financing all remain ahead, and the project’s value is tied to palladium and nickel prices.
