VICTORIA, BC / ACCESS Newswire / May 27, 2026 / Boron One Holdings Inc. ("Boron One" or the "Company") (TSXV:BONE), a company committed to advancing global decarbonization through the responsible development of its boron assets, is pleased to announce that it has executed a binding offtake agreement (the "Agreement") for the future sale of high‑value boron mineral concentrates and derivative products (collectively, "Product"). The Agreement provides for a three‑year term, commencing upon the Company's establishment of fully operational production facilities.

The Agreement is subject to the satisfaction of certain Conditions Precedent, including but not limited to the Company securing all required regulatory permits and approvals for development and operation of its planned mining and processing facilities, as well as the successful completion of a full‑scale plant qualification trial to the satisfaction of the buyer ("Buyer").

Under the terms of the Agreement, Buyer has committed to purchase a minimum of 25,000 tonnes of Product per year, with the option to increase volumes up to 50,000 tonnes per year. The Agreement contains a take-or-pay clause, committing Buyer to a penalty payment for certain shortfalls in its annual purchase.

Product pricing will be linked to prevailing competitive market prices, subject to an agreed minimum floor price. The initial price for the Product will be established 90 days prior to the commencement of full commercial production and will be subject to adjustment on each anniversary of that date for the duration of the Agreement.

Tim Daniels, President of Boron One, stated:

"This Agreement represents an important commercial milestone for the Company. With comparable boron products currently priced at levels ranging to well in excess of US$1,000 per tonne, the potential annual value of this offtake can be substantial. This anchor commitment strengthens our commercial foundation and supports the continued advancement of our development and financing initiatives."
