Halo Minerals PLC

("Halo Minerals", the "Company" and, together with its subsidiaries, the "Group")

Admission to AIM and First Day of Dealings

Investor Presentation

Halo Minerals PLC, the copper development company focused on extracting critical minerals from legacy mining waste, is pleased to announce the admission of its ordinary shares of £0.001 pence each in the capital of the Company ("Ordinary Shares") to trading on the AIM market of the London Stock Exchange ("Admission") and its First Day of Dealings. The Company's Ordinary Shares will commence trading at 8.00 a.m. today under the ticker symbol "HALO" and the ISIN GB00BP92JV57.

The Company has raised gross proceeds of £4 million pursuant to a placing of 22,222,223 Ordinary Shares at an issue price per Ordinary Share of 18 pence (the "Placing").  On Admission the Company will have 110,744,746 Ordinary Shares in issue with a market capitalisation of approximately £20 million.

The Group's principal asset is the Playa Verde Project (the "Project"), comprising six mining concessions over an area of approximately 13.57km² of copper-bearing tailings located in the coastal town of Chañaral in the Atacama Region of northern Chile.

The Company's Admission Document and information required pursuant to AIM Rule 26 is available on the Company's website at https://halominerals.co.uk/. 

Highlights:

·    The Group plans to advance the Project on an accelerated timeline to production 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 for the Project. 

·    The Project has a JORC compliant mineral resource of 53Mt at 0.24% Cu including Ore Reserves of 32.2 Mt with an average grade of 0.25% Cu which contain an in situ fine copper content of 79,359 tonnes. Based solely on the Ore Reserves set out in the Competent Person's Report, and based on a copper price of $5.30/lb and gold price of $4,300/oz, the Ore Reserves have an estimated net present value (NPV10) of US$154.1 million and IRR of 50.9% after tax.

·    The Company also intends to pursue additional growth opportunities in Chile and,

potentially, other international jurisdictions.

·    Global demand for copper is underpinned by its essential role in electrical conductivity, durability and corrosion resistance, making it difficult to substitute at scale in many applications. According to ICSG, copper demand is driven primarily by construction, electrical and electronic products, transport equipment and industrial machinery, with usage closely linked to global economic activity and infrastructure investment. Copper plays a key role in electrification and is also a key element required for the construction of data centres. Refined copper consumption has historically grown broadly in line with global GDP, reflecting copper's status as a core industrial metal.

·    Cairn Financial Advisers LLP is acting as the Company's Nominated Adviser with Global Investment Strategy UK Limited acting as the Company's Broker.
