Sayona’s Authier Lithium Project in Québec, Canada is a hard rock spodumene lithium deposit set to play a key role in the Company’s planned multi-project Abitibi lithium hub, as a source of supplementary ore for processing at NAL when production restarts.
Following the acquisition of the NAL mine and concentrator in August 2021, the Authier project’s operating strategy was revised to include only mining operations and waste and water management on-site.
The project is set to become a supplier of ore to Sayona’s nearby North American Lithium operation , which has an established concentrator, thereby minimising the need for mining infrastructure and related environmental impacts at Authier.
Sayona Mining acquired 100% of the Authier project in July 2016. The project’s key attractions include its near-term development potential, access to world-class infrastructure and labour, economical hydroelectric power and its strategic location near North American battery markets.
The Authier project is situated 45 kilometres northwest of the city of Val d’Or, a major mining service centre in Québec. Val d’Or is located approximately 466 kilometres north-east of Montreal. The project is easily accessed by a rural road network connecting to a national highway a few kilometres east of the project site.
The project area comprises 19 mineral claims totalling 653 hectares, and extends 3.4 kilometres in an east-west, and 3.1 kilometres in a north-south direction, respectively. The mineral claims are located over Crown Lands.
The deposit is hosted in a spodumene-bearing pegmatite intrusion. The deposit is 825 metres long, striking east-west, with an average thickness of 25 metres, minimum 4 metres and maximum 55 metres, dipping at 40 degrees to the north. The current pit optimisation has the mineralisation extending down to 200 metres depth but the deposit remains open in all directions.

In November 2019, Sayona completed a revised Definitive Feasibility Study confirming the project’s viability as a profitable and sustainable new lithium mine that will provide new jobs, investment and strong returns for all stakeholders.
