GR Engineering cements Yangibana rare earth project EPC contract

GR Engineering Services has been awarded an engineering, procurement and construction (EPC) contract with Yangibana Pty Ltd, a wholly owned subsidiary of Hastings Technology Metals Limited, for a beneficiation plant and associated infrastructure for the Yangibana rare earths project in Western Australia.

As previously announced on May 3, 2023, GR Engineering had entered into a binding term sheet with Yangibana Pty Ltd for these works.

The contract sum, including the provisional sum, is A$210 million ($138 million) as previously disclosed. This is made up of a fixed price component of A$180 million for the beneficiation plant and a provisional component of A$30 million mainly for the plant and tailings storage facility earthwork.

GR Engineering has commenced early works up to an agreed capped amount. The EPC contract is conditional on GR Engineering being issued with a commencement notice, which is dependent on Hastings finalising funding for the project as well as a number of other pre-conditions standard for an EPC contract.

Construction is planned to be complete in the March quarter of 2025 with first concentrate on truck in the June quarter of 2025

Under the A$210 million contract, GRES will design and construct the Yangibana beneficiation plant and all associated infrastructure, including engineering, manufacture, supply, installation, dry and wet commissioning, and testing of the facility over a period of less than 18 months. When completed, the plant will have a feed capacity of 1. 1 Mt/y and a rare earth concentrate output capacity of 37,000 t/y, Hastings says.

GR Engineering Services says it has entered into a binding term sheet with Yangibana Pty Ltd, a wholly-owned subsidiary of Hastings Technology Metals Limited, for the engineering, procurement and construction (EPC) of the beneficiation plant and associated infrastructure for the Yangibana rare earths project in Western Australia.

The project is approximately 250 km north east of Carnarvon.

Hastings said the plant will have a feed capacity of 1 Mt/y and a rare earth concentrate output capacity of 35,000 t/y of rare earth mineral concentrate at a grade of 27% total rare earth oxides.

GR Engineering and Hastings have agreed the material terms of the EPC contract in the binding term sheet. The EPC contract for the works will be finalised shortly and GR Engineering will commence early works. If the EPC contract is entered into, it is expected that the contract sum, including provisional sum, will be A$210 million ($140 million).

Tony Patrizi, Managing Director of GR Engineering, said: “GR Engineering is pleased to have received the binding term sheet for this world-class rare earths project in the Gascoyne region of Western Australia. It will be exciting to work on this project as it is focused on globally critical minerals that are used as key components for electric vehicles and wind turbines.”

Hastings, TOMRA see potential for XRT ore sorting at Yangibana rare earths project

TOMRA’s X-ray Transmission (XRT) ore sorting innovation has another positive industry reference to hand after Hastings Technology Metals said off-the-shelf technology had proven extremely effective at removing dilution on samples used in the testing program at its Yangibana rare earths project in Western Australia.

Testing on a 1.8 t sorted bulk sample had seen a 95.1% recovery of contained Nd2O3+Pr6O11 (neodymium and praseodymium), a 52% increase in head grade from 0.71% to 1.08% Nd2O3+Pr6O11, and a 37.1% mass rejection, Hastings said.

This shows XRT technology could be applied to separate out a barren waste stream from the ore, according to the ASX-listed company, presenting an opportunity to remove waste dilution material from the mining process before the material is fed into the processing plant – resulting in energy and reagent savings in the beneficiation circuit.

The testing involved the crushed bulk ore sample of 1.8 t being screened into two size fractions (10.5 mm) and (plus-10.5mm), with the sortable fraction (plus-10.5 mm)after being diluted with waste material at either 35% or 60% proportions screened on a TOMRA commercial sorter using XRT technology at 32 t/h feed rate.

In the base case, sorted ore samples, crushed and screened to plus-10.5 mm and diluted with 35% waste material, a total of 37.1% of the sample mass was rejected at a grade of 0.09%Nd2O3+Pr6O11, representing a loss of Nd2O3+Pr6O11 of just 4.9%, or an overall recovery of 95.1%Nd2O3+Pr6O11 in the ore. A corresponding 52% increase or upgrade in the ore head grade was achieved from 0.71% to 1.08% Nd2O3+Pr6O11.

In the sorted sample diluted with 60% waste material, the ore sorting test work program achieved an upgrade factor of 2.16 taking the feed grade from 0.43% Nd2O3+Pr6O11 to 0.93%Nd2O3+Pr6O11, while recovering 90.6% of the Nd2O3+Pr6O11, the company said.

Hasting said: “The full opportunity for including ore sorting technology into the Yangibana process flowsheet is still being assessed. Based on these test work results, technical and engineering programs will continue to investigate the benefits that can be realised across the project.”

The proposed beneficiation and hydro metallurgy processing plant at Yangibana 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, according to Hastings.

A definitive feasibility study in 2017, based on a 5.15 Mt reserve, detailed a production rate of 1 Mt/y to produce up to 15,000 t/y of mixed rare earths carbonate at Yangibana.
