The Cirrusl East (CE) Property is a large lithium-focused exploration property located in the Eeyou Istchee James Bay region of Northern Québec. The project spans 12,095 hectares across 224 mineral claims. It is situated roughly 3 km east of the Billy Diamond Highway and 55 km south of Camp 507—an important staging hub for mineral exploration in the region.
The CE Property benefits from its proximity to key infrastructure, including the Billy Diamond Highway and the regional airstrip at Camp 507. The 2024 field program utilized helicopter support based out of Camp 507, allowing for efficient access to mapped outcrops and prospective areas.
The property is underlain by tonalite, granodiorite, quartz diorite, and mafic gneiss, common host rocks for lithium–cesium–tantalum (LCT) pegmatites. These rocks are part of the La Grande Sub-province, which has seen increased exploration activity following multiple spodumene-bearing pegmatite discoveries nearby.
Prior to 2024, little systematic lithium exploration had been undertaken on the CE Property. However, government lake sediment data indicated multiple anomalies in lithium, cesium, and rubidium, which contributed to staking the property. Regional context supports its potential—several spodumene-rich pegmatites are located within 10–15 km.
Exploration activities in 2024 included:
Field crews identified numerous pegmatite dykes, some up to 20 m wide, composed primarily of quartz, feldspar, biotite, and muscovite, with occasional garnet. These features align with characteristics typical of fertile LCT systems.
A total of 83 rock samples were collected, with highlights including:
Several samples displayed low K/Rb (<150) and Nb/Ta (<8) ratios—key indicators of highly evolved pegmatites with LCT potential.
While no spodumene was observed in this phase, the widespread occurrence of pegmatite dykes, along with promising geochemical signatures, indicates that the CE Property holds significant potential for LCT-style lithium mineralization. The central and southeastern portions of the property remain largely underexplored and warrant further investigation.
