Opus One Gold Corp. announced 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 consists of a series of spodumene bearing pegmatites located along an ENE-WSW axis which might continue west onto the Wemindji property. Its 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 several 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.
