The 4,000 metre program will focus on the expansion of the resource following the successful drilling program in 2016 which significantly increased the resource and grade.
The 2016 drilling resulted in a 68% expansion of Authier’s contained lithium resource to 13.74 million tonnes grading 1.07% lithium oxide for 147,600 tonnes of contained lithium.
Importantly, drilling will also aim to define the size and lithium grade of the recently discovered, high-grade, northern pegmatite.
Mineralisation remains open in all directions at Authier.
Sayona’s flagship asset is the Authier lithium project comprising 19 mineral claims totalling 653 hectares.
Authier is a near-term development project and cash-flow generation opportunity for the company.
The dimensions of the deposit drilled to date are 825 metres long, with an average thickness of 25 metres, ranging from 4 metres to 55 metres.
Future mining or mineral extraction of the Authier deposit will be by open cut mining methods using drilling and blasting, and a conventional truck and shovel operation.
Sayona also recently secured an option to acquire an 871 square kilometre package of tenements in the world-class Pilgangoora district of Western Australia.
The package includes the Mallina project with newly identified spodumene pegmatite.
Drill program details
The drilling program has been designed with three aims, including:
- To improve the overall quality and expand on the size of its JORC resource.
The project now has nearly 19,000 metres of diamond drilling in 141 holes. Sayona’s plan is to increase the size and confidence levels of the resource and to study the merits of an expansion and/or the value adding potential of the project beyond what has been studied in the current pre-feasibility study which is nearing completion;
- Assess the resource potential of the newly discovered pegmatite; and
- Locate additional lithium mineralised pegmatites.
