MERYLLION RESOURCES APPOINTS TECHNICAL ADVISOR OF US EXPLORATION

Meryllion Resources Corp. has appointed Mark J. Pryor, SEG, IOD, FGS, SACNASP, as the company's technical adviser of U.S. exploration. Mr. Pryor is a geologist with a 40-year record of successfully advancing multiple precious metal, copper, coal, rare earths and lithium projects from discovery through to exploitation.

Mr. Pryor is currently executive vice-president of exploration for a private U.S. exploration group.

Mr. Pryor graduated from Aberdeen University, Scotland, with a degree in geology and mineralogy and has worked for international mining companies such as Anglo American, Placer Dome and Antofagasta as well as various private and public companies in the Americas, Africa, the former Soviet Union and Asia.

Mr. Pryor is currently non-executive director of Aston Bay Holdings and Kingsmen Resources Ltd., both TSX Venture Exchange-listed public companies.

On July 14, 2025, Meryllion announced that it had entered into a lease and option agreement with Bull Mountain Resources LLC (BMR) in respect of the Makenzie gold/silver/antimony project. Mr. Pryor introduced the company to BMR and its exploration projects.

Makenzie is one of the largest-known untested gold, silver and antimony anomalies in the state of Nevada.

The project lies approximately 48 kilometres north-northwest of Kinross Mining's Round Mountain gold project in Nye county, Nevada, which, according to Kinross Mining's website, poured its 15-millionth ounce of gold in 2018 and had proven and probable reserves of 1,883,000 ounces gold as of Dec. 31, 2024 (the qualified person has been unable to verify the information and that the information is not necessarily indicative to the mineralization on the property that is the subject of the disclosure).

The qualified person confirms that the geology and geochemistry noted at surface at Makenzie is similar in style (low-sulphidation epithermal) to the original Round Mountain footprint. However, due to the early stage of exploration at Makenzie, the potential to host economic mineralization requires further investigation. Meryllion has, in addition, staked a further 89 claims, for a total of 102 claims, covering 8.24 square kilometres.

Meryllion chief executive officer Richard Revelins commented: "We are delighted to have a person of the calibre of Mark join the company as technical adviser of U.S. exploration. Mark is a highly experienced and successful geologist who has been responsible for a large number of new discoveries and, in particular, discoveries which have subsequently become highly profitable mining operations across many continents. We are looking forward to getting into the field and initiating our exploration program as soon as permitting will allow."

Mark J. Pryor, SACNASP, is a qualified person as defined by National Instrument 43-101, Standards of Disclosure for Mineral Projects, and has reviewed and approved the scientific and technical disclosure set out in this news release. Mr. Pryor is an independent adviser to the company.
