Partial Relinquishment Report Exploration Licence 33194 Duke Project for the period 12 January 2023 to 12 January 2025

Abstract

This report describes exploration activities conducted over the relinquished portion of EL 33194 over the duration of tenure from initial grant on 12 January 2023 to partial relinquishment on 12 January 2025. Along with the adjacent EL 33101, EL 33194 forms the Duke Project, approximately 50 km northwest of Tennant Creek. HRE is exploring the area for the first time for rare earth elements (REE). The exploration model being investigated is an unconformity-type breccia-hosted hydrothermal xenotime REE deposit similar to those at Browns Range in WA. The Duke Project is geologically highly analogous to Browns Range, and contains similar sedimentary hosts, faulting, and an unconformity. A secondary target type for HRE is REE in regolith developed on the extensive but poorly-exposed Warrego Granite. During the period of tenure from grant on 12 January 2023 to partial relinquishment on 12 January 2025, no exploration was conducted on the relinquished portion of the title. Preliminary assessment indicated low prospectivity for REE on the relinquished portion of the title. The northeast portion of EL 33194 was surrendered to allow HRE to focus on more prospective areas of its Duke Project tenure.
