[{"type":"text","content":"Avalon Expands Resource Potential at Separation Rapids Lithium Project, Kenora ONToronto, Ontario--(Newsfile Corp. - May 4, 2023) - Avalon Advanced Materials Inc. (TSX: AVL) (OTCQB: AVLNF) (\"Avalon\" or the \"Company\") announces that the preliminary results from the winter 2023 diamond drilling program has potentially expanded the lithium resource at the Company's Separation Rapids Lithium Project. Thirteen holes totalling 4179 metres were drilled on the central main mass depth extensions of the resource. Of note, the final hole totalled 570 metres vertically through the deposit and confirmed visual petalite mineralization to a depth of 565 metres. This increases the potential depth of the deposit by 80% from the previously tested 315 metres deepest intercept. The other twelve holes intersected mineralization to the east, west and at depth from the existing resource and justify completion of an updated resource estimate for the Separation Rapids lithium deposit. Assays from four of the holes are pending.Drilling Program DetailsThe winter 2022/23 diamond drilling program included twelve drill holes on the existing resource and one vertical drill hole on the main centre of the deposit designed to examine the potential depth extent of the petalite mineralization. Twelve holes were designed to undercut historic maximum-known mineralized drill intercepts on the widest part of the Separation Rapids as step outs to expand the existing resource. The main deposit consists of a large, zoned vertical pegmatite dyke averaging 50-70m in thickness that has been structurally flattened, that includes both petalite and lepidolite accompanied by many narrower mineralized dykes of similar but variable lithium mineralogy. The dominant lithium mineral is petalite. The dykes tend to be lepidolite-rich on both the east and west extensions. Lepidolite is a lithium mica typically containing 7-8% Li2O content while petalite typically contains 4-4.5% Li2O, but with no impurities. The twelve holes were drilled over a total strike length of about 300 metres. Six holes (SR-22-81 to SR-23-86, assays for SR-23-85 pending) were designed to intersect the main part of the zone below existing drilling and were successful in extending the mineralization to depth (Table 2). Four holes (SR-23-87 to SR-23-90) were on the eastern extension of the deposit, which hosts...
