Alto Property

Overview

The Alto Property is located in the James Bay region of Northern Québec, approximately 3 km west of the Billy Diamond Highway and 55 km south of Camp 507. The project spans 4,136 hectares across 79 mineral claims and is 100%-owned. It sits within the La Grande Sub-province—an area recognized for hosting lithium–cesium–tantalum (LCT) pegmatites and several high-profile discoveries nearby.

Location & Accessibility

The property is accessible by helicopter and lies just west of the Billy Diamond Highway, one of the region’s key transportation corridors. Exploration crews were based at Camp 507 during the 2024 program, enabling efficient access to the property by air.

Geology

The property is primarily underlain by rocks of the Duxbury Formation, consisting of tonalite, granodiorite, and quartz diorite. The eastern portion includes metasedimentary units and mafic volcanic rocks belonging to the Bernou and Pilipas formations. These geological settings are prospective for rare-element pegmatites, especially those containing lithium, cesium, and tantalum.

Historical Exploration

Previous work in the area was limited and mostly focused on gold and base metals. However, several lithium-bearing pegmatites have been discovered just a few kilometers east of Alto:

  • The Pilipas Project (Ophir Metals) hosts spodumene-bearing pegmatite dykes with grab samples averaging 98% Li₂O
  • The Ninaaskumuwin Showing (Québec Precious Metals) returned grab samples up to 3.92% Li₂O and drill intervals of spodumene-bearing pegmatites

2024 Field Program

The 2024 exploration campaign included:

  • High-resolution LiDAR and satellite imagery

  • A 909 line-kilometre heliborne magnetic survey

  • Ground-based prospecting, mapping, and rock sampling

Field crews identified numerous pegmatite dykes across the property, typically composed of quartz, K-feldspar, and biotite, and occasionally garnet and muscovite. While no spodumene was identified, several dykes showed visual features consistent with LCT-type pegmatites.

Geochemical Results

A total of 61 rock samples were collected. Key results include:

  • Highest lithium value: 81 ppm Li (0.0174% Li₂O)

  • Tantalum: Up to 94.8 ppm Ta

  • Niobium: Up to 563 ppm Nb

Additionally, multiple samples returned low K/Rb and Nb/Ta ratios, which are often associated with evolved magmatic systems capable of hosting LCT pegmatites.

Exploration Potential

Although spodumene was not encountered during the 2024 program, the geochemical results and presence of pegmatitic intrusions indicate that the Alto Property remains a strong target for future lithium exploration. In particular, areas in the northwest and south of the property are still underexplored and represent high-priority follow-up zones.
