The program of selective reconnaissance sampling was conducted at the Viau-Dallaire, Viau and Gauthier prospects, with a total of 21 samples taken.
Defining drilling targets is the aim of exploration and sample results have focused on targeting at Viau-Dallaire and Viau.
Highlighted results include: 14 samples ranging from 0.96% to 2.47% lithium at Viau-Dallaire; four ranging from 0.22% to 4.5% at Viau; and three from Gauthier that did not return significant lithium grades.
The assays have very low iron content, averaging 0.63% iron.

Sayona managing director Dan O’Neill said the company was happy to confirm the potential to find wide zones of high-grade lithium mineralisation at the Viau-Dallaire and Viau prospects.
He said: “An initial drilling program is being planned for both prospects when access is established and the First Nations consultation is completed.”
The target to be drill tested at Viau-Dallaire is a 300-metre-long dyke, dipping 40 degrees north and 12-20 metres in thickness.
Three channel samples from Viau-Dallaire included 10.3 metres at 1.4% lithium, 11.15 metres at 0.84% and 18.95 metres at 0.94%.
At Viau, Sayona has mapped pegmatites up to 200 metres long and 30 metres wide.
Two separate channel samples returned grades of up to 2.77% and 1.37% over 3.2 metres, respectively.
An airborne geophysics survey previously conducted over a 9 kilometre long and 700 metre wide area confirmed a strong east-west magnetic anomaly coincident with historical surface mapping of pegmatites.
The host intermediate/mafic magnetic rocks confirmed through the survey have been intruded by discrete outcrops of sub-parallel lithium, beryllium and tantalum-bearing granitic pegmatite dykes.
The east-west trending pegmatite dykes dipping to the north, and hosted by metamorphic ultramafic and schist rocks, is a similar geological setting observed at Sayona’s Authier project.
Tansim is 82 kilometres southwest of Authier and comprises 65 mineral claims covering 12,000 hectares.
Historical exploration on the property has included mapping, sampling, geophysics and preparation of a Canadian NI43-101.
