Halo Minerals has officially adopted its new name following shareholder approval at a 6 January 2026 general meeting, completing its transition from Guardian Metals. The company said the rebrand signals a more focused strategy centered on the production of strategic and battery metals—particularly copper—by reprocessing low-risk, metal-rich historic mine waste already stockpiled at surface.
The name change comes as Halo advances plans to rejoin London’s Alternative Investment Market (AIM) after securing pre-IPO funding. Subject to market conditions and final due diligence, the company is aiming to complete an IPO fundraising and resume trading on AIM toward the end of the first quarter of 2026.
Copper-focused “circular economy” model
Chief Executive Andy Dennan described the rebranding as the beginning of a new phase for the company, emphasizing an approach designed to supply critical metals while promoting circular production and environmental restoration.
Halo’s strategy centers on extracting value from legacy mining materials rather than pursuing higher-risk greenfield exploration, positioning the business as aligned with sustainability objectives.
Playa Verde project in Chile
The company’s primary asset is the Playa Verde Project in Chile’s Atacama Region, which it says has the potential to “re-define sustainable mining” by combining copper production with environmental clean-up efforts in the Chañaral Bay area.
Halo acquired Playa Verde in March 2025. The project spans 15.25 square kilometers and is reported to contain a resource of 53 million tonnes grading 0.24% copper.
With copper widely regarded as a key metal underpinning electrification and grid expansion, Halo is presenting Playa Verde as an ESG-focused supply opportunity, targeting material that has already been mined and accumulated rather than initiating new large-scale extraction.
Part of a broader sector trend
The rebranding also reflects a wider trend across the mining industry. Sector data show nearly 300 mining companies changed their names between 2018 and 2024. In Australia alone, close to 70 ASX-listed firms rebranded in 2024, followed by more than 70 additional name changes among ASX-listed companies in 2025, many within the resources space.
