Sheffield Resources Limited announced that construction of its 50% owned Thunderbird Mineral Sands Project (Thunderbird) in northern Western Australia continues to progress on schedule. A key milestone was achieved during February 2023 with the delivery of LNG energy supply tanks to the Thunderbird site. Construction progress of the Wet Concentrate Plant and Concentrate Upgrade Plant continued, with installation of equipment and mechanical systems in progress.

Site electrical installation activities are underway and key infrastructure components to support the borefield are in place. Installation of the thickener support structure has also commenced. Completion of construction activities and initiation of commissioning activities remains on target for late 2023 with construction over 75% complete.

The project is nearing the top of the `S-curve' with monthly percentage progress expected to naturally slow as the project continues to approach 100% completion.
