Auclair Project

Cygnus’ Auclair Project is a large 417 square kilometer landholding located just 60km north-east of the Whabouchi lithium mine (55.7Mt @ 1.4% Li2O), owned and operated by Nemaska Lithium. 

The Auclair project boasts excellent infrastructure with year-round access via gravel roads that service Hydro Quebec transmission corridors, with power lines and access roads crossing through the project area.

Historical exploration in the region has focused on gold, with limited campaigns for base metals and uranium. Prior to Cygnus, no lithium exploration had been undertaken on the property.

First assays confirm a thick, shallow and strongly mineralised intersection of 43.7m at 1.15% Li2O

Multiple Discoveries

Recent drill result from Pegasus is comparable to major deposits in James Bay and demonstrates the huge opportunity at the Auclair project.

Exploration has discovered multiple major spodumene bearing pegmatite trends over 6km of strike with the discoveries of Auriga, Lyra and Pegasus.

First drilling results of the most significant of these discoveries, Pegasus, returned a highlight intersection of 43.7m (true width) @ 1.15% Li2O from 46.4m, including 4m @ 3.0% Li2O which includes 1m @ 5.9% Li2O.

To date, Pegasus consists of two large spodumene-bearing pegmatites outcropping side by side and measuring up to 75m long x 50m wide, and 65m long x 30m wide, respectively. Significant coarse, spodumene mineralisation has been observed throughout the Pegasus outcrop up to 40% in places, with individual spodumene crystals exceeding 1m in length.

Drilling over the Auriga Trend has established multiple spodumene-bearing pegmatites up to 13.9m wide over 1.9km strike thought to represent a potential large swarm system. Results from surface sampling along the Auriga trend demonstrate Auclair to be a highly fertile system returning significant grades of up to 6.5% Li2O.

The Lyra discovery is a single outcrop with exposed dimensions of 60m x 15m wide and is mostly covered by vegetation. Stripping back the moss revealed zones of dense spodumene mineralisation with crystals up to 10cm in length.

All three spodumene discoveries to date fall within a highly prospective 10km LCT fractionation corridor, identified through the discovery and sampling of pegmatites, with assays returning favourably low K/Rb ratios.
