Canada Silver Cobalt Works Inc. and Granada Gold Mine Inc. announced positive bench-scale leach test results achieving 99% extraction of the contained alkali metal rubidium from drill core sourced from the recently discovered EV battery metals zone at the Granada Gold deposit in northwestern Quebec. Discovery at Granada: The recent discovery of a potentially large, low-grade alkali and rare earth mineralized zone at Granada Gold Mine meets the Company criteria. With the addition of rubidium carbonate salt to the electrolyte, battery performance in both lithium-ion and sodium-ion EV batteries improves in charging rates and cyclability.

The EV battery metals zone consists of several alkali and rare earth metals discovered near surface and at depth in early 2021 during a 30,000-meter infill drilling program on the northern section of the Big Claim at the Granada Gold Mine property. Two drill holes, separated by 1,600 meters, were tested and assayed. The deepest hole, drilled to a depth of 1,626 meters, intersected 21 distinct mineralized zones varying in width from 2.8 to 177 meters.

The best grade, over a wide width, for rubidium was 340 grams per tonne over 53 meters. Current pricing for rubidium carbonate salt is about USD 1.00 per gram. As this EV metal mineralized zone sits stratigraphically on top of the Gold mineralized zone, it may be mined to produce gold bullion as a primary recoverable metal with a rubidium carbonate salt as a by-product there- by significantly increasing the value and economics of the property.

Leach Test: Drill core from the EV battery metals discovery zone, from the northern part of the Big Claim at Granada Gold Mine, was used for the test work at SGS Canada. The core was crushed and ground to 80% passing 200 mesh, followed by a conventional flotation process to remove pyrite. Pyrite removal minimizes chemical consumption during the Re-2Ox leaching process.

Multiple bench-scale tests were undertaken to optimize leach extraction, achieving 99% of contained rubidium metal, by varying leach time, chemical concentrations, and temperatures.
