Drilling ramping-up following oversubscribed fundraise

Critical Mineral Resources plc («CMR», «Company») is pleased to report that
following the recently completed and heavily oversubscribed fundraise, diamond
drilling with two rigs is ramping-up over the coming weeks as the weather
improves. Drilling during H1 is designed to produce Agadir Melloul’s maiden
resource estimate, targeted for publication in early Q3 2026.

Key Highlights

· Accelerated drill programme at Agadir-Melloul
· Two diamond rigs ramping-up to two shifts per day each
· 20 holes planned per month from mid-February
· Agadir Melloul’s maiden resource estimate targeted for Q3 2026

Charlie Long CEO commented:

«With two rigs now turning, we anticipate an extremely productive drill
programme and for an internal maiden resource to be modelled by late Q2 and for
the JORC compliant resource estimate to be published in early Q3.

Drilling has been intermittent in recent weeks due to inclement weather. This
week both rigs are operating on day shifts, and once the weather improves night
shifts will be introduced. From then on we should be drilling 20 holes per month
equating to approximately 1,000m.

For a near-surface project like this, metres drilled is less important than the
number of holes drilled. Each hole will range from 20m to 50m depth, with the
occasional deeper hole to drill-test the basement as we continue the hunt for
mineralised rhyolite.

It’s worth reiterating that near-surface mineralisation is quite unusual and a
huge economic advantage in terms of opex, upfront capex, reserve development
capex and ongoing sustaining capex».
