Piacenti & Son wins mineral sands mining contract at Thunderbird project

Kimberley Mineral Sands, the Sheffield Resources and Yansteel joint venture steering the Thunderbird mineral sands project in Western Australia, has awarded Piacentini & Son Pty Ltd a nine-year mining services contract the project.

The agreement, which could be extended by a further five years following the initial contracting period, builds on Piacenti’s work delivering three dozer mining units to the Coburn mineral sands project, also in Western Australia.

In accordance with the latest agreement, Piacentini shall provide a Mining Unit Plant (MUP) to support Thunderbird and undertake mining activities using all necessary heavy mobile equipment to excavate and deliver ore to the MUP in a dozer push ore mining operation, ahead of delivering processed materials to the Wet Concentrator Plant, Sheffield Resources said.

Piacentini, Sheffield says, is a very experienced mineral sands mining contractor and has supported a range of mining companies, in mineral sands and other commodities, in Australia and overseas for over 40 years.

Sheffield Resources Executive Chair, Bruce Griffin, said: “The award of the mining services contract to mining services operator Piacentini & Son Pty Ltd is one of the final remaining commercial steps to completing the project financing arrangements for Thunderbird and we look forward to Kimberley Mineral Sands and Piacentini establishing a long and successful partnership as we bring the world-class Thunderbird Mineral Sands Project into production in the near future.”

The Coburn definitive feasibility study, released in June 2020, outlined a mine life of 22.5 years at a mining rate of 23.4 Mt/y.

Pacific Energy secures hybrid power PPA for Thunderbird mineral sands project

Pacific Energy says it has signed a 15-year Power Purchase Agreement with Kimberley Mineral Sands (KMS) for the Thunderbird mineral sands project in Western Australia.

Under the agreement, Pacific Energy will design, build, own and operate a 16 MW high efficiency gas power station combined with 2 MW of battery storage and an on-site LNG storage and re-vaporisation facility with 10 days’ storage capacity.

The agreement accommodates the future addition of solar energy and the parties will commence working on this augmentation as soon as possible to create a larger hybrid power facility, Pacific Energy says.

Pacific Energy CEO, Jamie Cullen, said: “We are extremely pleased to have been selected to deliver an efficient power generation and gas storage solution for KMS’ flagship Thunderbird project.”

Sheffield Resources Executive Chair, Bruce Griffin, added: “We look forward to KMS expanding their relationship with Pacific Energy, and for the support from Pacific Energy to deliver a stable and efficient energy solution for Thunderbird. We welcome this important milestone step in establishing Thunderbird as the next major mineral sands producer in the near future.”

Construction is due to commence in December 2022.

KMS is owned 50:50 by Sheffield Resources and Yansteel.

A bankable feasibility study released earlier this year outlined a A$484 million ($325 million) Stage 1 project using a Single Mining Unit Plant that underpinned a 10.4 Mt/y mining operation and a processing plant design feed rate of 170 t/h. The Stage 2 project saw a duplication in year five of Stage 1 mining underpinning a 20.8 Mt/y mining operation and an increase in the processing plant feed rate to 290 t/h.
