Sheffield Resources is focused on the development of the flagship Thunderbird Mineral Sands Project, one of the world’s largest, undeveloped zircon-rich mineral sands deposits. Thunderbird is owned by Kimberley Mineral Sands Pty Ltd, a 50/50 joint venture between Sheffield and YGH Australia Investment Pty Ltd (Yansteel), formed in 2021 to develop the Thunderbird Mineral Sands Project. Thunderbird is one of the largest and highest grade mineral sands discoveries in the last 30 years. The 2022 Bankable Feasibility Study shows Thunderbird is a technically low risk, that generates strong cash margins from globally significant levels of production over a decades long mine-life. Thunderbird will generate a high-quality suite of mineral sands concentrate products well suited to market requirements.
