Projects Overview

Sheffield Location Map

Sheffield has assembled a globally significant portfolio of 100% owned mineral sands projects, located in Western Australia.

The Company's mineral sands projects comprise:

  • The flagship high-grade, zircon-rich Thunderbird Mineral Sands Project located midway between Broome and Derby in the Canning Basin
  • The Central Canning project, located 350km south of Thunderbird in the Canning Basin
  • The Barton project, located in the north eastern Eucla Basin in South Australia
  • The Eneabba project, located near Geraldton in WA’s Mid-west region
  • The large scale McCalls chloride ilmenite project, located 110km north of Perth

Thunderbird 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 while the Mineral Resource contains 3.23 billion tonnes @ 6.9% HM, including a higher grade component of 1.05 million tonnes @ 11.9% HM with very high in-situ zircon (0.93%) and ilmenite (3.3%) grades. These grades, its size, and surface outcropping nature, place Thunderbird in the top tier of HMS deposits globally.

The Eneabba Project has combined mineral resources totalling 7.6Mt of contained heavy mineral with combined measured, indicated and inferred resources totalling 346 million tonnes @ 2.2% HM across seven deposits.

The McCalls Project contains 53Mt of heavy mineral, in an Inferred Resource of 3.65 billion tonnes @ 1.47% HM. McCalls contains over 40Mt of chloride ilmenite grading 59-66% TiO2 and is a longer term strategic asset.
