Our Equity Capital Markets team has recently advised Cairn Financial Advisers (Cairn) and Global Investment Strategy UK (GIS) on the admission of Halo Minerals plc (Halo) to AIM, together with an associated £4 million placing.
Cairn acted as nominated adviser to Halo in relation to the IPO, with GIS acting as sole broker on the placing.
Halo is a copper development company focussed on extracting critical minerals from legacy mining waste. Its principal asset is the Playa Verde Project – comprising six mining concessions over an area of almost 13.57 sq km of copper-bearing tailings in northern Chile. Halo plans to advance the Project to production on an accelerated timeline – utilising funds raised on admission, which is expected to take the Project to a final investment decision, or to a stage at which alternative project funding options are available.
Halo shares were admitted to trading on 30 March 2026, with the ticker ‘AIM:HALO’ and a market capitalisation on admission of approximately £20 million.
Sam Hudson (Partner), Natalia Fryda (Senior Associate) and Vikash Vaitha (Associate) from our Equity Capital Markets team acted on the transaction.
We were delighted to play our part in assisting the nominated adviser and broker on the IPO of Halo Minerals. The Playa Verde Project has fantastic potential and it is great to see another international mining company in the critical minerals space choose London as its listing venue. We look forward to following Halo’s progress as it moves towards a final investment decision.Sam Hudson

We are well-positioned to support the global transition to sustainable energy through the extraction of critical minerals, delivering both environmental and economic value.

I would like to thank our team and investors for their support as we enter this new and exciting phase for the business and look forward to providing further updates as we accelerate our flagship project towards production."
