Boron One Holdings Inc. reported positive results from bench-scale metallurgical testing conducted on samples from its 100% owned Piskanja Boron Property located in Serbia ("Piskanja"). The testing returned commercial grades of colemanite concentrate, ulexite concentrate, and boric acid, all which meet or exceed the specifications of products commercially available from other leading boron producers. The testing produced salable quality of concentrates and derivatives from across all three of the distinct boron mineral zones found at Piskanja - colemanite, ulexite and mixed borate zones.

This is important to ensure the utilization of all borate materials from within the Piskanja deposit, and thereby maximizing revenue potentials in any future production. The testing methods utilized industry standard, "off the shelf" equipment and protocols (grinding, attrition scrubbing, calcination, and/or acid leaching) to achieve the results. The testing was successful in defining optimal parameters (such as grind size, scrubbing time, calcination time and temperature, acid concentrations and leach times, etc.) to optimize recoveries and B2O3 content in finished products.

As a result of the positive bench-scale testing, the Company is now conducting semi-industrial bulk-scale metallurgical tests on all three of its boron types. Highlights of metallurgical tests: Colemanite: A blended sample, representing each of the colemanite zones within Piskanja (with the test sample blended head grade of 40.2% B2O3, approximating that of the average ulexite grade found within Piskanja overall), underwent standard grinding and calcination, and resulted in the production of a sales-grade ulexite concentrate with a 58.22% B2O3 content (and a 72.06% mass recovery), along with a Na2O concentrate of 9.2%. Using altered parameters for grinding and calcination, mass recovery was increased to 76.56%, with an acceptable B2O3 grade of 54.0%, and a NaO2 concentrate of 8.49%.
