Bruce Lake Property

Overview

The Bruce Lake Property is located in the Eeyou Istchee James Bay region of Northern Québec, covering 5,976 hectares across 115 mineral claims. The property lies approximately 7.5 km southeast of the Billy Diamond Highway and 40 km south of Camp 509. The region is emerging as a highly prospective area for lithium exploration, with several discoveries nearby.

Location & Accessibility

Bruce Lake is easily accessible via helicopter from the nearby 509 Camp, which served as a base of operations during the 2024 exploration program. Its proximity to the Billy Diamond Highway and existing infrastructure provides a strategic advantage for future work.

Geology

The property is situated within the La Grande Sub-province, an area underlain by granodiorite, quartz diorite, tonalite, and intrusive gabbroic units. These rocks are typical hosts for lithium–cesium–tantalum (LCT) pegmatites in similar geological settings across Québec and Ontario.

Historical Exploration

Little historical work has been carried out on the Bruce Lake Property, but regional geochemical datasets have identified lithium, cesium, and tantalum anomalies in lake sediment samples. Nearby projects such as the Pilipas and Ninaaskumuwin lithium showings support the area’s exploration potential.

2024 Field Program

The 2024 exploration work included:

  • High-resolution LiDAR and satellite imagery

  • A 787 line-kilometre heliborne magnetic survey

  • Ground prospecting, geological mapping, and sampling

Numerous pegmatite dykes were identified across the property, many featuring quartz, feldspar, biotite, garnet, and muscovite—common indicators of LCT-type pegmatites. One outcrop hosted coarse feldspar crystals measuring up to 10 cm.

Geochemical Results

A total of 61 samples were collected. Results include:

  • Highest lithium value: 75 ppm Li (0.0161% Li₂O)

  • Tantalum: Up to 85.1 ppm Ta

  • Niobium: Up to 624 ppm Nb

Several samples returned low K/Rb and Nb/Ta ratios, typical of geochemically evolved granites capable of hosting lithium mineralization.

Exploration Potential

Although no spodumene was found during the 2024 program, the identification of evolved pegmatite dykes and anomalous geochemical indicators suggests strong potential for lithium-bearing pegmatites. The western and central zones of the property remain underexplored and are recommended for follow-up exploration.
