IRW-PRESS: Meridian Mining Plc: Meridian Mining provides corporate update
LONDON, United Kingdom, December 8, 2025 / Meridian Mining Plc (TSX: MNO), (Frankfurt/Tradegate: N2E) (OTCQX: MRRDF) (“Meridian” or the “Company” – is pleased to announce that Mr. David Halkyard has been appointed Chief Financial Officer (CFO) of the Company effective November 25, 2025. See Meridian’s September 2 press release 2025
. Additionally, the Company announces the appointment of Ms. Catherine Apthorpe as Corporate Secretary following the resignation of Ms. Mariana Bermudez. Ms Apthorpe has over 20 years of legal experience, including 15 years as in-house counsel at various mining companies, including as legal advisor and company secretary at Capital Limited & Amara Mining PLC and as a non-executive director at Panthera Resources PLC. Ms. Bermudez has served as Corporate Secretary since February 2022 and resigned from the Company to pursue other business opportunities.
The Company also announces that the name change See Meridian’s Information Circular 2025
from Meridian Mining UK Societas to Meridian Mining Plc with effect from the opening of the stock exchange on December 10, 2025. The change is due to the company’s conversion into a public limited company (PLC) in the UK in November 2025, which was approved by shareholders at the Annual General Meeting and Extraordinary General Meeting See Meridian’s press release dated June 24, 2025
. Therefore, the company’s ISIN has changed to GB00BVPND783 and at the same time the company’s CUSIP has changed to G6017H 103. The previous ISIN and CUSIP numbers are now invalid. The trading symbols and share capital remain unchanged.
Gilbert Clark, CEO, comments: I would like to congratulate David on his full-time position as CFO of the company. The expansion of the capacity of Meridian’s finance team since his tenure as interim CFO has been exceptional and is on track to meet Cabaçal’s future project financing needs. I am delighted that Catherine has joined our leadership team. She brings a wealth of experience in corporate management and legal advice to the company. At the same time as these welcome new additions, Mariana is leaving the company. I would like to thank her for her great contribution to the company’s success during a period of strong growth for Meridian, and we all wish her all the best in her new role.
Finally, the name change to Meridian Mining Plc reflects our UK headquarters and final administrative closure in relation to Brexit. We are now focused on executing the DFS for Cabaçal and the greater exploration opportunities in 2026.
About Meridian
Meridian Mining focuses on:
– The advanced stage development and exploration of the Cabaçal VMS gold-copper project;
– The first resource definition on the second higher-grade VMS project at Santa Helena as the first stage of the Cabaçal Hub development strategy;
– Exploration of the Cabaçal VMS belt at the regional scale to expand the Cabaçal Hub strategy; and
– Exploration in the Jaurú and Araputanga greenstone belts (all of the above areas in the state of Mato Grosso, Brazil).
The Pre-Feasibility Study Technical Report (the Pre-Feasibility Study Technical Report) dated March 31, 2025 entitled Technical Report and Pre-Feasibility Study for the Cabaçal Gold-Copper Project in accordance with NI 43-101 describes an after-tax net present value (NPV)5 of $984 million and an IRR of 61.2% at a pre-production capital cost of $248 million, resulting in a return of capital in 17 months (assuming a metal price scenario of $2,119 per ounce gold, $4.16 per pound copper and $26.89 per ounce silver). Cabaçal has a low all-in sustaining cost (AISC) of US$742 per ounce of gold equivalent and a production profile of 141,000 ounces of gold equivalent over the life of mine, reflecting a high metallurgical recovery rate, a low strip ratio of 2.3:1 over the life of mine and the low operating cost environment in Brazil.
