Welcome to the website of American Pacific Borates Limited (ASX:ABR). ABR’s Fort Cady Borate Mine in California hosts a multi-generational Borate resource where boric acid, gypsum and potassium sulfate (SOP) will be produced for the large North American specialty fertiliser market and new high end technologies like electric vehicles and space shuttles.

ABR completed an Enhanced Definitive Feasibility Study (eDFS) in April 2020, which built on the starter project as announced in January 2019. In February 2021, the Company updated the eDFS to bring forward early SOP production which included the addition of a new Phase 1C.

The addition of Phase 1C enables the decoupling of SOP and boric acid from the previous Phase 1B. This has the effect of delivering a very low capex for the new Phase 1B and a stronger CY2023 EBITDA given the ability to bring forward SOP production.

  • Phase One A will target the production of 20kstpa of SOP (K2SO4) and 9kstpa of boric acid (H3BO3)
  • Phase One B will target SOP production of 60kstpa
  • Phase One C will target boric acid production of 81kstpa.

In June 2020, the Company secured total financing of A$77M to fully finance Phase One A, and was subsequently awarded its final operational permit in August 2020. Substantive construction activities have commenced, with first production on track for Q3 CY2021.

The Project is forecast to directly employ around 250 people in full production.
