Project Commissioning Update

Tungsten West (AIM:TUN), the mining company focused on restarting production at the Hemerdon tungsten and tin mine ("Hemerdon" or the "Project") in Devon, UK, is pleased to provide an update on Project commissioning.

The Company confirms that it will begin commissioning of its phased production ramp-up later this month. In advance of this, Tungsten West has commenced an enhanced programme of stakeholder engagement, including local community and regulators, to ensure all parties are informed of the timing, scope and staged nature of the commissioning activities.

This programme is consistent with the Company's previously stated timeline, which includes recommissioning of the fines gravity circuit and downstream processing facilities during Q3 2026.  The Company remains on track for the next milestone of commissioning, the coarse gravity circuit, in Q4 2026, with full project commissioning expected in Q1 2027.  The Project is also forecast to be completed within budget.

Alongside the phased production ramp-up, Tungsten West is well advanced with its recruitment programme and remains committed to hiring a significant proportion of its workforce from the local area.   The Company has now recruited over 100 employees, targeting total recruitment of 350 by early in Q1 2027. 

Jeff Court, CEO of Tungsten West, commented:

"We are making rapid progress on the restart of Hemerdon with the first phase of recommissioning starting this month. This marks another significant milestone towards full project commissioning in Q1 2027, and I would like to thank the team, our partners, stakeholders and shareholders for the hard work that has been undertaken to date to reach this step."
