NOT FOR DISTRIBUTION TO U.S NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES

MONTREAL, May 16, 2024 (GLOBE NEWSWIRE) -- Opus One Gold Corp (TSX-V: OOR) (the "Company" or "Opus One") is pleased to announce that it has made the final payment of $200 000 to Magna Terra Minerals, allowing it to acquire a 100% interest in Noyell gold property, located 25Km south of the town of Matagami in the southern part of the Eeyou Itschee Baie James, Casa Berardi mineral district.

Major points in favor of our Noyell Gold project are:

• Noyell project is very well located, 25KM south of Matagami, Quebec, a mining friendly community.
• Noyell is located in Quebec province, benefiting from a very favorable mining jurisdiction, especially where it is located.
• Noyell project is located within the well-known Casa Berardi mineral belt.
• Noyell is located 14 KM from regional road 109.
• An operating gold mill is located 70Km southwest, close to regional road 109.
• The Noyell project is at advanced definition drilling stage on Zone 1.
• The mineralized zone shows good widths and gold grades.
• The mineralized zone is shallow, easy to follow and to understand and demonstrates excellent lateral and depth continuity.
• The mineralized zone shows a dip south 67degrees.
• Noyell has an excellent development potential, the mineralized structure still being open for exploration toward East, toward West and at depth. So far, we only drilled down to a maximum 350 metres depth.
• Low-cost exploration in comparison with remote projects, thanks to its location and ease of access
• Noyell is located above 49^th parallel therefore allowing for extra tax deductions and refunds.

Louis Morin, CEO of Opus One, commented: A very important step has been achieved by Opus One Gold Corp. I would like to personally thank all of our supporters who allowed us to successfully reach this milestone. Financing conditions remain difficult for junior exploration companies, and we managed, despite these challenges, to successfully complete the acquisition of a 100% interest in the Noyell gold property, which constitutes the company's main asset.
