Surge Battery Announces Laboratory Trials Produce Technical Grade Lithium Carbonate Exceeding 99% Purity

West Vancouver, British Columbia--(Newsfile Corp. - April 9, 2024) - Surge Battery Metals Inc. (TSXV: NILI) (OTCQX: NILIF) (FSE: DJ5) (the "Company" or "Surge") is pleased to announce that the first stage of metallurgical testing on clays from the Nevada North Lithium Project (NNLP) has achieved the goal of producing lithium carbonate at a dry-basis purity greater than 99% Li2CO3.

Mr. Greg Reimer, Chief Executive Officer, and Director commented, "Beyond our initial metallurgical and analytical works in 2023 to estimate acid consumption and identify the clay types, we are very pleased to have taken the next step and have passed the important 'proof of concept' trial showing that the clays of our Nevada North Lithium Project can be used to produce lithium carbonate exceeding 99% purity. In doing so, we have managed the technological risk sufficient to warrant the next step, which will include upsizing the laboratory trials to build a sufficient inventory of technical grade lithium carbonate that we can purify to demonstrate if the NNLP clay is a suitable source to produce battery grade lithium carbonate."

The process flow sheet included attrition of the lithium-bearing clay, sulfuric acid digestion, filtration to separate the remnant clay, silica removal, removal of magnesium, calcium and excess sulphate from the solute, followed by precipitation using soda ash (Na2CO3), and recycled lithium carbonate for crystallization. Major impurities (Al, CA, Fe, K, Mg, Na, SO4, Si) content accounted for just 0.17%, with all other mainly not detectable by ICP analysis, and those that could be measured accounting for a total of just 0.006%.

Tests were conducted on a variety of horizons of varying clay lithium concentrations and mixtures of source clay layers. This series of preliminary bench-scale process tests was conducted by Kemetco Research Inc, of Richmond, BC, Canada. Kemetco has built a team of experts in lithium processing, having accumulated experience across a number of lithium projects and mineralization types.

Subsequent stages of process tests will advance to proving the steps required to purify the lithium carbonate to battery grade concentration and impurity levels and optimizing the process to reduce reagent and water consumption while improving recovery.
