In March 2022 NAIF made an Investment Decision to offer financial assistance of up to $160 million to Kimberley Mineral Sands (KMS) to support the development of the Thunderbird Mineral Sands Project in the Kimberley region of Western Australia.
Proponent Background
Formed in January 2021, Kimberley Mineral Sands is a 50:50 joint venture between Sheffield Resources and YGH Australia Investment (Yansteel) for the Thunderbird development on the Dampier Peninsula, midway between Broome and Derby.
Project Overview
Thunderbird will generate a high-quality suite of mineral sands concentrate products. These products include a zircon concentrate and a magnetic concentrate that contains a high-quality ilmenite suitable for smelting into chloride slag or for manufacturing titanium dioxide pigment.
During Stage 1 construction, Thunderbird is expected to support a workforce of approximately 350 people and establish a drive in, drive out operational workforce within the Kimberley region. Significant public benefits will be delivered within the Kimberley community through a range of business and contracting opportunities.
Australian Industry Participation
Australian Industry Participation (AIP) requirements ensure full, fair and reasonable opportunity for Australian industry to compete for work. This includes work in major public and private projects in Australia, and procurements or projects receiving Australian Government funding of $20 million or more.
NAIF projects must comply with the Australian Government’s AIP policy.
The AIP Plan developed for the Thunderbird Mineral Sands Project is available here.
Public Benefit
Over the construction period and first 20 years of operations, the project is forecast to generate an increment to northern Australia’s real Gross Regional Product of $1.85 billion in present value terms. The project is also forecast to generate 225 new jobs in northern Australia during construction and 345 ongoing operational roles for the life of the mine.
As part of its Indigenous Engagement Strategy, KMS has committed to achieving strong Indigenous employment, business and social outcomes in the region. The company is working with the Joombarn-buru Traditional Owners and collaborating with key Indigenous organisations across the West Kimberley. The IES covers obligations on supporting economic benefits through employment and business contracts, cultural heritage protection, environmental management, cultural awareness training, and a social impact assessment.
Sheffield is extremely pleased by the level of support shown by NAIF and the Federal Government for the Thunderbird Mineral Sands Project. The NAIF commitment will enable KMS to finalise project funding requirements for Thunderbird and progress construction activities, with the aim of delivering first production in early 2024

The Joombarn-Buru Aboriginal Corporation (JBAC), holds Native Title over the area that the Thunderbird mine is located. JbAC works to preserve cultural heritage, promote economic development, and deliver community initiatives. Their deep cultural knowledge and connection to country spans coastal ecosystems, river systems, and inland ranges, all rich in biodiversity and cultural significance. For generations, Traditional Owners across the West Kimberley have used sophisticated knowledge of country to navigate land and sea country. Today, through JBAC, the Traditional Owners continue to uphold their cultural responsibilities while engaging in opportunities that ensure self-determination and sustainable development on their lands.
Indigenous Engagement Strategy Commitments
The Thunderbird Project Coexistence Agreement (TPCA) contains the below requirements:
- Commit to First Nations employment targets of 10% by year two, 25% by year four, 40% by year eight of operations, prioritise Joombarn-Buru Traditional Owners, establish an Aboriginal Training Fund, and provide mentoring support to traditional owner employees.
- Prioritise First Nations contractors starting with Joombarn-Buru Traditional Owners when awarding up to $5m annually in construction and $10m in operational contracts, while establishing a Business Development Committee and a register of First Nations businesses.
- Support an Agreement Implementation Committee (IC) comprising Joombarn-Buru Aboriginal Corporation (JBAC) and KMS representatives to oversee the implementation of the TPCA.
- KMS in partnership with JBAC, conduct an Aboriginal Social Impact Assessment, including a community skills audit, to inform employment, training, and development strategies aligned with best practice models.
- Implement a Communication Strategy with regular reporting to the Implementation Committee on employment, procurement, and training outcomes, and continued engagement with the Joombarn-Buru community.
- Employ at least two Joombarn-Buru Rangers, and work closely with Traditional Owners on heritage surveys, cultural awareness training, and caring for country.
Indigenous Engagement Strategy Outcomes
- As of 31 March 2025, the Thunderbird workforce employed by KMS and its primary contractors totalled 401, with 22% identifying as Aboriginal, 17% as female, and 50% residing in the Kimberley. Among the workforce, 21 employees identified as Joombarn Buru.
