Pure Resources (ASX: PR1) has reported grades of up to 11.69% lithium during a recent site visit to the Järkvissle nr 100 reservation, situated in the Västernorrland region of Sweden that hosts the country’s largest lithium deposits.
The grades were derived from handheld SciAps Z-903 Laser-Induced Breakdown Spectroscopy (LIBS) analysis of outcrop mapping and sampling completed at the project.
A total of 45 samples were collected and delivered to a testing laboratory in the Swedish city of Piteå for detailed analysis.
Peak assay
A peak LIBS assay from a triphylite-lithiophilite sample returned a result of 11.69% lithium along with observed high to very-high rubidium content in potassium-feldspar and muscovite.
It indicated an extensive presence of highly-fractionated, muscovite-rich pegmatites and pathfinder minerals including triphylite-lithiophilite, cassiterite and potentially zinnwaldite which are indicators for spodumene mineralisation.
Claims location
Pure’s claims are adjacent to and along strike of Sweden’s most advanced lithium deposit, known as the Järkvissle pegmatite sites, owned by Asera Mining AB.
The company is targeting a high magnetic unit interpreted to be a band of mafic/ultramafic derived amphibolite, which is host rock to potential lithium-caesium-tantalum (LCT) pegmatites.
Highly-prospective area
Pure executive chair Patric Glovac said the early results suggest the company is in a highly-prospective area for lithium.
“With the identification of common pathfinder elements and highly-elevated lithium in mica content, we are confident that there is potentially an exciting discovery opportunity in front of us,” he said.
“Three known spodumene pegmatite occurrences are described just a few hundred metres east of the perimeter boundary of our license area, and at least one of them shows considerable volume proven by drilling… we look forward to planning and executing the next phase of exploration at the Järkvissle reservation in the search for Scandinavia’s next spodumene discovery.”
Mr Glovac said further work in the area would include geological mapping and sampling, ionic leach soil geochemistry, a high-resolution magnetic survey, and more drilling.
