Company Profile & Strategy
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 located midway between Broome and Derby in northern Western Australia, a low risk mining jurisdiction with a close proximity to Asian markets.
Thunderbird is one of the largest and highest grade mineral sands discoveries in the last 30 years. Sheffield’s 2019 Bankable Feasibility Study Update shows Thunderbird is a technically low risk, modest capex project that generates strong cash margins from globally significant levels of production over an exceptionally long mine-life spanning multiple decades.
In January 2021, Sheffield and Yansteel executed binding agreements for the formation of a 50:50 Joint Venture (Kimberly Mineral Sands Pty Ltd, KMS) to own and develop the Thunderbird Mineral Sands Project and adjacent tenements on the Dampier Peninsula. The parties have agreed that the development concept for Stage 1 of the Project will be a 10.4mt per annum mine and process plant producing a zircon rich non-magnetic concentrate and LTR ilmenite.
Yansteel subscribed for a 50% interest in KMS and provided A$130.1m in project equity funding. Sheffield shall fund any project equity shortfall between A$130.1m and A$143m, less Project costs incurred prior to a Final Investment Decision (“FID”). KMS will secure project finance and, if required, project equity in excess of A$143m will be funded 50:50 by Yansteel and Sheffield. The Yansteel A$130.1m project equity investment in KMS, together with the A$12.9m funding under the Yansteel Share Placement completed on 12 August 2020 and combined with existing project financing is expected to deliver a fully funded project.
Thunderbird will generate a high-quality suite of mineral sands products with specifications suited to market requirements. These products include a zircon products and ilmenite suitable for manufacturing titanium dioxide pigment or smelting into chloride slag.
In addition to the northern Canning Basin tenement package, Sheffield owns 100% of the Eneabba and McCalls mineral sands projects located in the established North Perth Basin mineral sands province in Western Australia’s Mid-west region. These projects have substantial mineral resources and are well located with respect to existing infrastructure. In December 2017, Sheffield spun out its non-mineral sands exploration assets into a new, independent company Carawine Resources Ltd which successfully listed on the ASX on 14 December 2017.
