Highlights

· The acquisition of Kalahari Copper establishes the Company as a large
landholder in two emerging copper belts, subject to licence renewal: the Kaoko
Basin in Namibia and the Kalahari Copper Belt in Botswana, both of which are
under-explored in comparison to their prospectivity.
· The Acquisition thereby gives the Company the opportunity to explore
extensive areas of highly prospective terrain in emerging exploration districts,
adjacent to significant recent discoveries, in line with its ambition to become
a mid-cap copper and future metals development group.
· Appointment of Andrew Benitz as a Non-Executive Director, effective
immediately on Admission.
· Change of name to Serval Resources Plc, to occur once processed by Companies
House.
· Launch of new company website at https://servalresources.com/.

Robin Birchall, Executive Director and Chief Executive Officer, commented:

«This is a landmark day for the Company as the AIM market will provide the
foundation from which to grow the business. I would like to thank our team and
all our advisers who have worked so hard to get us to this point. We would also
like to thank all the investors who have supported us in our plan to create a
mid-cap copper and future-metals exploration and development group. Our priority
now is to put the funds to good use by advancing our exciting exploration
targets in Namibia and Botswana.»
