Update on metallurgical testing at Klein Aub

Unicorn Mineral Resources Plc, (LSE: UMR), is today pleased to announce
positive results from the preliminary metallurgical testing of the samples
from the Klein Aub Copper Mine, located in Namibia.  As previously noted, the
metallurgy of the slimes and tailings is complex, with high concentrations of
carbonates that render any acid leaching uneconomic.  Instead, the Company
has been investigating the use of glycine to extract the copper in association
with Draslovka (www.draslovka.com (http://www.draslovka.com) ), a world leader
in glycine leaching technology.

The preliminary tests showed an initial recovery rate for the copper of
between 60-70% from the slimes and 35-45% from the tailings.  Work will now
be undertaken to optimise the reagent with aim of increasing the recoveries to
enhance the economic value of the copper that may be extracted.  In addition
and given the significant increase in the silver price in recent months, the
Company will investigate the possibility of using a dual leaching process to
extract the silver alongside the copper.

Historic drilling and assay work completed since 2020 has indicated a
potential deposit of 5,587,000 tonnes of ore contained in the historic
tailings and slimes dam at the Klein Aub Mine and with a potential total in
situ metal content of up to 15,460 tonnes of copper and 1.4 million ounces of
silver.  This in situ metal content is in addition to the several identified
unmined parallel lodes extending along strike to the northeast to the former
underground mine workings.

Encouraged by the initial testing, the Company will now commence work on the
legal documentation for the transaction with the aim of completing the
transaction and securing a 75% interest in the Klein Aub Copper Mine by April
2026.

Commenting on the initial tests, Paddy Doherty, Chairman, said:

"The potential value of the in-situ metal at Klein Aub has been clear from the
initial due diligence by Unicorn.  The issue has been how to extract it
economically.  We are delighted to now be working with a team of experts in
environmentally friendly glycine extraction technology from Draslovka, which
looks to be the key to unlocking the value at Klein Aub."
