Name of the Project
Fort Cady borate mine project.

Location
The project is located in the south-eastern desert region of San Bernardino County, in California, in the US.

Project Owner/s
American Pacific Borates.

Project Description
An enhanced definitive feasibility study (DFS) has proposed splitting Phase 1 of the project, which involves the delivery of about 82 000 t/y of boric acid and 36 000 t/y of sulphate of potash (SoP), into Phase 1A and Phase 1B to conserve costs.

Phase 1A will target the production of 6 000 t/y of boric acid and 40 000 t/y of SoP, while Phase 1B will increase boric acid production to 90 000 t/y using the knowledge gained from the initial 6 000 t/y operation.

Phases 2 and 3 of the project remain the same as in the DFS. Phase 2 will increase pro­duction to 245 000 t/y of boric acid and 73 000 t/y of SoP, while Phase 3 will produce 408 000 t/y of boric acid and 109 000 t/y of SoP.

Based on the three-phase approach, the project has a mine life of about 21 years.

Potential Job Creation
At full production the project is expected to employ about 250 people.

Net Present Value/Internal Rate of Return
The enhanced DFS estimated a net present value, at an 8% discount rate, of $1.97-billion, compared with $1.43-billion in the DFS modified in January 2019.

The enhanced DFS estimates an internal rate of return of 39.4%, compared with 40.5% in the modified DFS.

Capital Expenditure
The increased production will require a greater capital spend, with capital spend forecast at $737.9-million for the enlarged project, compared with the original cost of $526.2-million of the DFS modified January 2019.

Phase 1A will cost $50.3-million.

Phase 1B is expected to require a capital investment of $156-million.

Phase 2 is estimated at $268.3-million.

Phase 3 is estimated at $263.2-million.

Planned Start/End Date
First production is targeted for the third quarter of 2021.
