Avalon Advanced Materials Inc. said April 5 that it has started a 10-hole 2,000-meter diamond drilling program at its Separation Rapids lithium project near Kenora, Ontario.
The program will focus on expanding the existing mineral resource of lithium pegmatite mineralization, open along strike and depth, and quantifying lithium mineralization in the resource associated with lepidolite and other lithium micas.
Drilling will also test a target area 1 kilometer west of the known resource, and collect geotechnical data for groundwater studies and mine planning in advance of permitting for site development.
Lithium subzones in Separation Rapids were identified in lepidolite, which has potential for production of both a lithium carbonate product and lithium hydroxide product, as estimated in the company's preliminary economic assessment.
Avalon expects the drilling program to be completed over the next six to eight weeks, followed by an updated resource estimate, as well as recent progress on process development work this summer.
