Martello update - Sakoose Drill Permit Received

Sakoose Drill Permit Received

Richmond Hill Resources plc is pleased to announce that the drilling permit for the Martello Project has been approved and issued by the Ontario Ministry of Energy and Mines. The permit authorises mechanised core drilling and is valid until 20 July 2029. Appendix 1 further below shows the location of the approved drill pads.

The proposed drill hole locations may be refined after further analysis of the current exploration data and/or as the drill program advances, depending on geological observations and findings during the program.

Pending receipt of assay results from the recent field program, Critical Discoveries will update the current model with the field data collected to confirm whether the existing drill plan remains the best option.

Hamish Harris, Chief Executive Officer, commented:

"It's pleasing to get the drill permit obtained in a timely fashion.

We look forward to working with Critical Discoveries to support the next phase of drill targeting at our priority target in Sakoose."

The Directors of the Company are responsible for the release of this announcement.
