American Pacific Borates Limited (ASX: ABR) is a publicly listed company focused on advancing its 100% owned Fort Cady Borate Project located in Southern California,USA.
Fort Cady is a highly rare and large colemanite deposit and is the largest known contained borate occurrence in the world not owned by the two major borate producers Rio Tinto and Eti Maden. The Project has a JORC mineral estimate of Resource of 120.4 million metric tonnes (“Mt”) at 6.5% B2O3 (11.6% Boric Acid equivalent [H3BO3] and 340 ppm Lithium (5% B2O3 cut-off) for 7.8 Mt contained B2O3 (13.9 Mt H3BO3):
Total Measured MRE of 38.87 Mt at 6.70% B2O3 (11.91% H3BO3) and 379 ppm Lithium (5% B2O3 cut-off grade) for 2.61 Mt contained B2O3 (4.63 Mt H3BO3)
Total Indicated MRE of 19.72 Mt at 6.40% B2O3 (11.36% H3BO3) and 343 ppm Lithium (5% B2O3 cut-off grade) for 1.26 Mt contained B2O3 (2.24 Mt H3BO3)
Total Inferred MRE of 61.85 Mt at 6.43% B2O3 (11.42% H3BO3) and 322 ppm Lithium (5% B2O3 cut-off) for 3.98 Mt contained B2O3 (7.07 Mt H3BO3)
In total, in excess of US$60m has been spent at Fort Cady, including resource drilling, metallurgical test works, well injection tests, permitting activities and substantial pilot- scale test works.
ABR expects the Fort Cady Borate Project can quickly be advanced to construction ready status due to the large amount of historical drilling, downhole geophysics, metallurgical test work, pilot plant operations and feasibility studies completed from the 1980’s to early 2000’s
