Name of the Project
Yangibana rare earths project.

Location
Upper Gascoyne region, Western Australia.

Project Owner/s
ASX-listed Hastings Technology Metals.

Project Description
The project includes the development of five openpit mines, groundwater abstraction, an on-site processing plant, tailings storage facilities, access and haul roads, as well as supporting infrastructure such as accommodation facilities, administration buildings and an airstrip.

The project proposes the construction of a beneficiation and hydrometallurgy processing plant, which will treat rare earths deposits, predominantly monazite, hosting high neodymium and praseodymium contents to produce a mixed rare earths carbonate that will be further refined into individual rare-earth oxides at processing plants overseas.

The one-million-tonne-a-year operation is expected to produce 15 000 t/y of mixed rare earths concentrate and about 8 850 t/y of total rare-earth oxides over 13 years.

Potential Job Creation
Not stated.

Net Present Value/Internal Rate of Return
The project has an after-tax net present value, at an 8% discount rate, of A$549-million and an internal rate of return of 28%, with a payback of 2.6 years.

Capital Expenditure
The project’s cost was revised in March 2019 to $427-million.

Planned Start/End Date
Not stated.

Latest Developments
Hastings Technology has reported a 37% increase in the total rare-earth oxide (TREO) reserve estimate at its Yangibana project.

The estimate is currently 16.7-million tonnes grading 0.95% TREO.

TREO tonnage has increased by 15%, to 158 400 t, with contained neodymium/praseodymium increasing by 18%, to 58 300 t.

The increased ore reserve includes a maiden ore reserve for the Simon’s Find deposit, which is estimated to host about 1.7-million tonnes at 0.57% TREO, of which 52% is neodymium-praseodymium.
