Thunderbird Mineral Sands Project
The Thunderbird Mineral Sands Project is Sheffield’s flagship project due to its large scale, high grade, high in-situ zircon content and its potential to produce premium products which could displace lower quality products in the market. The Company completed a Bankable Feasibility Study (BFS) in March 2017 which confirmed Thunderbird as a world class mineral sands project based on a 42-year mine life and globally significant annual production of zircon and ilmenite.
The Thunderbird BFS is underpinned by one of the world's largest and highest grade, zircon and ilmenite-rich mineral sands ore reserves. The ore reserve stands at 680.5Mt @ 11.3% HM (proven and probable) while the Mineral Resource contains 3.23 billion tonnes @ 6.9% HM, including a higher grade component of 1.05 million tonnes @ 12.2 % HM with very high in-situ zircon (0.93%) and ilmenite (3.3%) grades (Measured, Indicated and Inferred). These grades, its size, and surface outcropping nature, place Thunderbird in the top tier of HMS deposits globally.
