Boron One Holdings Inc. reported positive results from bulk-scale metallurgical testing conducted on samples from its 100% owned Piskanja Boron Property ("Piskanja"). The testing returned a commercial grade of colemanite concentrate with a 42.2% B2O3 content (75.3% recovery), which meets or exceeds the specifications of colemanite concentrate products commercially available from other leading boron producers. Bulk-scale metallurgical test results for ulexite, and mixed borate zones are expected shortly.

Colemanite, and mixed borates zones represent the entire composition of Piskanja mineralization. Highlights of metallurgical tests: Colemanite: A blended sample weighing approximately 170 kg, representing each of the colemanite zones within Piskanja (with the test sample blended head grade of 36.8% B2O3, closely approximating that of the average colemanite grade found within Piskanja overall) underwent grinding, attrition scrubbing and screening, and resulted in the production of a sales-grade colemanite concentrate with an 42.2% B2 O3 content (at a 75.3% recovery rate).
