Chalice Appoints Dan Brearley as Chief Operating Officer

Chalice Mining Limited (“Chalice” or “the Company”, ASX: CHN) is pleased to announce the appointment of highly regarded project manager and executive Mr Dan Brearley to the newlycreated role of Chief Operating Officer, further strengthening its senior leadership team.

Mr Brearley, who will join the Company on 3 March 2025, will lead all aspects of the ongoing studies and development of the 100%-owned Gonneville PGE-Nickel-Copper-Cobalt Project (“Gonneville” or “Project”) in Western Australia, with his appointment marking another important step in the advancement of this unique critical minerals project.

Mr Brearley’s expertise and global experience with major resource project developments will be critical in finalising studies and approvals for the Gonneville Project ahead of a Final Investment Decision.

Mr Brearley is a decorated project builder in the precious and base metal industry, bringing over 25 years’ project management experience in the development of significant mining projects across Queensland, Western Australia, Indonesia, China, Romania, Papua New Guinea, South Africa, Dominican Republic and other jurisdictions.

His most recent role was General Manager Projects for Evolution Mining (ASX: EVN), where he spent three years with oversight and responsibility for the delivery of all studies and major projects across their portfolio. Prior to that, he was Project Manager for Barrick Gold (NYSE: GOLD), where he led the US$1.3Bn expansion of the Pueblo Viejo Project. He also spent eight years with Newcrest Mining as a Project Manager, leading several successful large capital projects.

Mr Brearley is a civil engineer and has deep practical experience across major projects in Australia, giving him an ideal skillset to lead the unique Gonneville Project.

Chalice’s General Manager Project Development, Mr Mike Nelson, has decided to leave Chalice to pursue a new international career opportunity. He will stay with the Company until 21 March to ensure a smooth handover of responsibilities for the Gonneville Project to Mr Brearley.

Chalice Managing Director and CEO, Alex Dorsch, said: “I am delighted that Dan has decided to join Chalice and, on behalf of the Company, I’d like to welcome him to our executive team. We are approaching an important phase of the pre-development journey with the Gonneville Project and Dan’s experience in late-stage studies, financing and project execution will be incredibly valuable in the coming years.

“Dan’s experience in leading project teams through construction and delivering exceptional results will be critical as we move beyond the ongoing Pre-Feasibility Study into a Feasibility Study, engineering, financing and offtake for our flagship project. Dan brings an exceptional track record of delivery in complex precious and base metal projects.”

“I’d like to personally thank Mike for his contributions to the Project over the past two years, where he has been integral in re-shaping the process flowsheet and development strategy for the project in particular. We wish him well as he takes on his next project role.

Commenting on his appointment, Mr Brearley said: “I am excited to have this opportunity to join the Chalice team and contribute to the future growth of the Company, which is focused in the near term on delivering the PFS for Gonneville. The opportunity to lead the Project was highly attractive, given its uniqueness and scale, the solid foundational work completed to date, and the growing demand for the basket of metals it will produce.

“Gonneville in my view has the potential to be developed in stages, adapting to the current low commodity price environment, but ultimately morphing into a multi-generational large-scale mining operation over time. There are very few opportunities like this in the industry, so I look forward to working with the team, building further on my understanding of the Project and meeting the wider project stakeholder group.”

This announcement has been authorised for release by the Board of Directors.
