Business Update

As set out the Company's announcement dated 24 April 2026, the Company raised £3 million (before expenses) from existing and new investors. It also issued shares to offset over £1 million in amounts owed to creditors. This important balance sheet event allows the Company to be fully funded for its current exploration programme in Botswana and for working capital purposes..

In June 2026, CEO Rémy Welschinger and Botswana Exploration Manager Titus Chanda, a highly experienced exploration geologist with extensive knowledge of the Kalahari Copper Belt, attended the Future of Mining Summit in Gaborone, Botswana, the country's flagship mining conference. The event brought together mining companies, government representatives and industry participants from across the region to discuss developments across the Kalahari Copper Belt and the broader mining sector.

The Company also remains committed to maintaining regular dialogue with shareholders and the wider investment community. In June 2026, Rémy Welschinger participated in a live investor event with Proactive Investors, providing an update on the Company's projects and related activities.

Botswana - Virgo

Work continues to progress well at the Virgo Project in Botswana's highly prospective Kalahari Copper Belt, where the Company's geophysical programme is nearing completion, ahead of drilling scheduled to commence in August 2026. The Company has now extended the IP survey coverage to keep following the interpreted D'Kar Formation-Ngwako Pan Formation ("DKF-NPF") contact and improve drill targeting. The Company expects to announce the results of the geophysical programme shortly.

The Company is in advanced discussions with drilling contractors and expects to make a selection during the month of July. The drilling programme will test priority targets generated through the integration of the expanded IP survey, magnetic survey and detailed geological interpretation.

As part of the programme, the Company has completed detailed field verification of historical discovery hole locations and incorporated these into the final drill planning process ahead of mobilisation.

Virgo remains the only junior-held licence package within MMG's highly prospective Zone 5 Corridor.

Zambia - Kabompo West

During the quarter, and as announced on 27 May 2026, Arc reached a comprehensive Settlement Agreement in Zambia, bringing to a full and final conclusion all outstanding legal disputes relating to Kabompo West. Procedurally, the requisite consent judgements are being filed with the relevant Zambian courts and the Company will make a further announcement upon completion of this process. The settlement enables the Company to focus fully on developing the project's long-term potential.

The Company is pursuing a dual-track strategy. Alongside ongoing discussions with major mining companies regarding potential strategic opportunities for its assets, Arc is conducting a comprehensive review of its extensive geological, geophysical and drilling database. As part of this process, the Company is assessing the potential application of AI-assisted geological interpretation to complement traditional exploration techniques and unlock further value from the existing dataset.

The Board believes Kabompo West remains one of the largest and most prospective exploration land packages within Zambia's Western Domes region.
