Watson Farley & Williams (“WFW”) advised Halo Minerals PLC (“Halo”) on its admission to trading on the AIM market of the London Stock Exchange (“AIM”) and its associated placing of shares.
The net proceeds of the placing will be used to fund the accelerated exploration and development of the Chañaral Copper project, Halo’s principal asset on the acquisition of which WFW also advised. The project comprises six mining concessions spanning approximately 13.57km2 of copper-bearing tailings in the coastal town of Chañaral in Northern Chile’s Atacama Region.
Previously known as Guardian Metals PLC, Halo is a leading mining company dedicated to the exploration, development and production of battery metals, especially copper, focussed on extracting critical minerals from legacy mining waste.
The WFW London Mining team that advised Halo was led by Corporate Partner Sarah Williamson, supported by Senior Associate Clementine Freeth, Associate Toby Hunt and Trainee Morgan Biggins.
Sarah commented: “We are pleased to have supported Halo through every stage of this journey—from the acquisition of its flagship asset to its successful admission to AIM. The proceeds raised will enable meaningful advancement of the Chañaral Copper project and we’re proud to have contributed to the next phase of Halo’s growth. As one of few natural resource IPOs in recent years, this transaction evidences renewed investor appetite for mining opportunities. Being instructed on matters such as this reflect WFW’s full-service capabilities in the mining sector”.
Halo Minerals CEO Andrew Dennan added: “WFW were instrumental in delivering our successful AIM IPO. Having worked with them before, we knew their strong capabilities and that their advice was clear, proactive and consistently added value throughout the process”.
