Canadian lithium explorer Sayona Mining (ASX: SYA) has returned high-grade lithium assays from reconnaissance sampling at its Tansim lithium project in Quebec.
The company today reported 21 grab samples taken over exposed pegmatites at three prospects in the project: Viau-Dallaire, Viau and Gauthier.
At Viau-Dallaire, 14 samples returned assays ranging from 0.96% lithium oxide to 2.47% lithium oxide.
High-grade results were also achieved at Viau, ranging from 0.22% lithium oxide to 4.5% lithium oxide.
Although the Gaunthier samples did not return significant lithium grades, Sayona managing director Dan O’Neill said the company remained encouraged by the wide zones of high-grade lithium mineralisation at the first two prospects.
“An initial drilling program is being planned for both prospects when access is established and the First Nations consultation is completed,” he said.
Sayona announced its progressive acquisition of Tansim from Matamec Explorations at the start of this year. The project covers 120 square kilometres and is prospective for lithium, tantalum and beryllium.
It is located 82km south-west of the company’s flagship Authier lithium project, which has been estimated to hold a mineral resource of 20.46 million tonnes grading 1.02% lithium for 209,476t of contained lithium.
Sayona’s current exploration program at Tansim is aimed at defining drilling targets at the Viau-Dallaire and Viau prospects.
Viau-Dallaire is a pegmatite dyke measuring 300m long and between 12-20m thick. At the second prospect, Viau, pegmatites have been mapped over an area up to 200m long and 30m wide.
A recent airborne geophysics survey has confirmed a strong east-west magnetic anomaly that corresponds with historical surface mapping of pegmatites over an area measuring 9km long and up to 700m wide.
In addition, 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.
According to Sayona, a similar geological setting has been observed at the Authier project.
Shares in Sayona rose 12.12% to A$0.037 on the news by mid-afternoon trade.
