Opus One Gold Corp. Acquires a Second Property With Lithium Potential Near Q2 MIA Lithium Discovery

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

MONTREAL, June 28, 2023 (GLOBE NEWSWIRE) --  Opus One Gold Corp (TSX-V: OOR) (the "Company" or "Opus One") is pleased to announce that it has reached an agreement for the acquisition of a 100% interest of a second property for lithium in the Eeyou Itschee Territory, James Bay, Quebec, in a district that is currently being intensively explored for its lithium potential by mining companies.

After months of property evaluations, the company elected to get involved in areas of the James Bay which are particularly active for lithium exploration. It took a while to the management to secure properties because of the restrictive parameters established by the company for property acquisition:

1. The properties have to be located within prospective districts.
2. The properties have to be accessible by land for low-cost exploration and development (trucks or ATV's)
3. The properties have to show excellent potential for discoveries.
   

The terms of the option agreement between Opus One and the owners consists of a cash payment of 40,000.00$CDN, payable upon the closing of a future financing within the next 6 months; 4,250,000 Opus One shares, valued at 0.05$ per share and 1,000,000 warrants exercisable at 0.10$ for a period of 18 months; all of the above divided 50% within the two claims owners. The transaction is conditional upon TSX Venture Exchange (the "TSXV") approval

The chosen property, called ?Wemindji', is located near the village of the same name, immediately to the west of the MIA Lithium discovery (Q2 Metals). It consists of 1 claim block covering 2,590 hectares. The property is located north of the road leading to Wemindji and is easily accessible with ATV's. The MIA Lithium discovery consist of a series of spodumene bearing pegmatites located along an ENE-WSW axis which might continue west onto the Wemindji property.

A preliminary evaluation of the area consisting of a study of satellite images indicated the presence of several elongated pale colored rock formations, well exposed because of recent historical wildfires that are consistent with the presence of pegmatite dykes.

The company is gearing up for a summer prospecting, mapping and sampling program on both properties recently acquired in the area (Wemindji and LaGrande). A field crew should be mobilized in late July. The field program is fully funded.

Louis Morin CEO of Opus One commented: "Through the partnership we established with seasoned and dedicated prospectors, we are acquiring a second lithium property that again, corresponds precisely to our corporate criteria as for accessibility and mineral potential. At Opus One we are always careful to wisely spend our funds to create maximum value for our shareholders. We secured a first-class competent crew to conduct our upcoming summer field program and we are fully financed to proceed.
