NEWS RELEASE

OCTOBER 25TH, 2023 TRADING SYMBOL: TSX-V: OOR

OPUS ONE GOLD CORP OBSERVED SEVERAL PEGMATITES ON ITS RECENTLY

ACQUIRED LITHIUM PROPERTIES IN THE EEYOU ITSCHEE JAMES BAY AREA

NOT FOR DISTRIBUTION TO U.S NEWSWIRE SERVICES OR FOR

DISSEMINATION IN THE UNITED STATES

Montreal, October 25th, 2023, Opus One Gold Corp (TSX-V: OOR) (the “Company” or

“Opus One”) is pleased to announce that it has observed several pegmatites during the

completion of its field season on its Wemindji and LaGrande properties located in the

northern portion of the Eeyou Itschee James Bay mineral district.

As the world's focus on sustainable energy sources continues to grow, the demand for

lithium has surged, primarily driven by its critical role in lithium -ion batteries used in

electric vehicles and renewable energy storage systems. To meet this increasing

demand, exploration for lithium resources has expanded to previously untapped areas,

and one such area of great interest is James Bay.

Eeyou Itschee James Bay, located in Northern Quebec, is known for its geological

potential, and recent surveys have identified significant lithium prospects in the region's

pegmatites. These lithium pegmatites are rich in the mineral spodumene, a key source of

lithium.

The first property acquired by Opus One Gold is called ‘LaGrande” and is located within

the La Grande lithium exploration district. The property is located approximately 70 km

to the west of the Corvette discovery (Patriot Battery Metals) and 10 km to the south of

the Cancet discovery (Windsome Resources). The property consists of 3 claim blocks

covering an area of 1,541 hectares. Prospecting programs outlined the presence of at

least 18 pegmatites on the three blocks. Two of the three blocks are accessible by the

Trans-Taïga road using ATV’s. The third (and smallest) block is more remote.

The second 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 s of a

series of spodumene bearing pegmatites located along an ENE -WSW axis which might

continue west onto the Wemindji property . Our initial prospecting program outlined a

dozen pegmatites sites on the Wemindji property.

The summer field program was delayed because of severe wildfires covering the entire

region. Only in the fall could the properties be finally accessed by land. A prospecting

and sampling program was completed on both properties in September. The prospecting

program identified multiple pegmatites occurrences on both properties. The pegmatite

intrusions range in thickness from a meter up to sev eral meters. Their length is quite

variable but could be hundreds of meters. In most cases, pegmatite extensions are

hidden under overburden which makes it difficult to assess their true length.

Lithogeochemical sampling was carried out on both properties in order to identify lithium

mineralization which is mostly in the form of spodumene (lithium silicate) in the region.

All samples were sent to an accredited laboratory for analysis. Results are pending.

Louis Morin CEO of Opus One commented: Because of the large territory covered by

exceptional regional scale wildfires during summer 2023 period, access by road to our

Eeyou Itschee James Bay projects was blocked until September. Fortunately, compliant

weather in September allowed two prospector crews to access properties, open trails

and perform exploration work on two distinctive trips. Many pegmatite occurrences have

been observed on both properties. Collected samples have been submitted to ALS

laboratory for assays. We consider our initial pegmatites observations as very

encouraging for future work follow-up on our lithium properties.

Coming up before year end is a field sampling program both on Noyell and Courville gold

properties to collect more data for future drill programs. Although our Noyell is at a

definition drilling stage, we intend to acquire better knowledge from some unexplored

portions of the property. Those planned sampling programs for 2023 are fully financed.
