Copper developer Halo Minerals is intending to seek admission of trading shares on the Alternative Investment Market (AIM), as part of the London Stock Exchange, in March 2026.
As part of the company’s initial public offering (IPO), £4 million ($7.55 million) has been raised through a placing. Cairn Financial Advisers are acting as the company’s nominated adviser, with Global Investment Strategy UK acting as the broker.
This news comes after Halo changed its name from Guardian Metals earlier this year, reflecting a renewed focus on producing key strategic and battery metals, particularly copper.
In December 2025, the company proposed the name change amid preparations for a return to the London AIM Market following completion of a pre-initial public offering (IPO) capital raise.
The Alternative Investment Market (AIM) is the London Stock Exchange’s market for small and medium size growth companies. It has served as a platform enabling growth-oriented companies to access public capital and drive global economic progress for over 30 years.
CEO Andrew Dennan says admission to AIM represents a milestone for Halo.
“The board believes that being publicly traded will enhance our visibility, broaden our shareholder base and provide a platform from which to pursue our long-term growth strategy,” Dennan says.
Halo is focused on its Playa Verde Project, which comprises six mining concessions over a 13.57km2 area of copper-bearing tailings located in the Atacama region of northern Chile.
In February 2026, the company released a component persons report on the Playa Verde Project, confirming a substantial resource and reserve base.
The resource base contains total resources of 53.44 million tonnes @ 0.24% copper, in-situ fine copper content of 125,820 tonnes, including the declared ore reserves of 32.2 million tonnes @ 0.25% copper, with an in-situ fine copper content of 79,359 tonnes.
Playa Verde also has an net present value of US$154.1 million ($217.63 million) and an internal rate of return of 50.9% post-tax, based on the ore reserves only.
As part of the project’s mine plan, initial mineable resources and reserves total 34.2 million tonnes to produce 60,329 tonnes of refined copper. The mine plan is based on dredging and processing 5 million tonnes per year of tailings, with an overall metallurgical recovery of 72%.
