Purebase Corporation Enters into a Material Definitive Agreement

IONE, CA, November 8, 2023 – Purebase Corporation (OTCPK: PUBC), (“Purebase”) Purebase Corporation entered a Second Amendment to the Materials Extraction Agreement (“Agreement”) on November 1, 2023 with US Mine, LLC (“US Mine”), which Agreement provides for US Mine to provide kaolin clay for Purebase’s planned production of metakaolin to be used as supplementary cementitious material (SCM).

The Amendment provides, among other things, for the cancellation of US Mine’s option to purchase up to 116,000,000 shares of the Company’s common stock and in lieu thereof the Company will pay US Mine a monthly production royalty of $20.00 per ton of kaolin clay extracted from property owned by US Mine.

Purebase Corporation CEO, Scott Dockter, stated “this amended agreement is all about sustainability for Purebase. We will have decades of resources available to help reduce the carbon emissions that occur during the manufacturing of cement. One of the biggest concerns we’ve heard from the cement industry is that the materials to make a lower carbon cement can be in short supply. I believe this agreement will help alleviate those concerns.”
