Richmond Hill Resources PLC (AIM: RHR) announces that, further to the
announcement on 5 February 2026, a third-party contractor has now completed a

Overhauser base stations.

From 16 – 25 February 2026, the contractor completed an airborne magnetic
survey using an Unmanned Aerial Vehicle (UAV) over the Martello Gold Project
near Dryden, Ontario, Canada. The survey was flown for Richmond Hill Resources
totalling 773.7 line-kilometres and was an add on to the previously flown
survey in 2023.

Richmond Hill has engaged Critical Discoveries to write an assessment report

             This survey now completes the gap in previous work over our
licences in the Martello Gold Project and provides further information on the
project as we look forward to our maiden drill campaign which we expect to
commence shortly. I look forward to updating the market with respect to this
shortly.                    ”
