Table 01: Exploration Target for the Remorse Iron Deposit. Tonnage Range Fe Grade Range Tonnes Mt (Upper) Tonnes Mt (Lower) Fe % (Upper) Fe % (Lower) 110 50 32 30 Note: The potential quantity and grade of the Exploration Target is conceptual in nature and as such there has been insufficient exploration drilling conducted to estimate a mineral resource. At this stage, it is not guaranteed further exploration will result in the estimation of a mineral resource. The Exploration Target has been prepared in accordance with the JORC Code (2012) and the Valmin Code (2015). Table 02: Mineral Resource Estimate for the Remorse Iron Deposit reported at 28% Fe cut-off grade. Classification Mass Mt Volume thousand m3 Density t/m3 Average Value Fe% Inferred 63.5 16 900 3.76 30.6 Total 63.5 16 900 3.76 30.6 Laboratory analysis has also shown the Remorse Deposit to exhibit excellent metallurgical properties TEM has also identified significant potential upside to these with the outlining of the Halo Iron Target several kilometres to the West of Remorse. GISA Deal TEM previously signed an MOU with prospective Mid-West GreenSteel developer Green Steel and Iron Pty Ltd (GISA) and an option agreement for GISA to acquire the Remorse Iron Deposit in a share-based deal with the ultimate intention of GISA to progress to IPO and development of the MidWest Green Iron and Steel facility. GISA has secured further MOU’s with other potential magnetite iron ore producers in the region and has also submitted an application for the Federal Government Green Iron Fund, which is under consideration. Page 2 | 9 ​ ASX : TEM ​ 2026-07-30 | Quarterly Report June 2026 Mount Magnet Mt Magnet is a prolific multi-million-ounce gold mining centre with numerous large-scale, long-life open pit and underground mines. It has been operated by major resources companies such as Western Mining Corporation and Harmony Gold Ltd, and more contemporary successful mid-tier companies such as Ramelius Resources Ltd and Westgold Ltd. Figure 02: Mt Magnet and Range Project Overview Range Located in the heart of the Mount Magnet mineral field and 5km along strike from the prolific +6Moz Mount Magnet Operations, the Range Project consists of 17 tenements for 20km2 . The project is interpreted as containing similar geology as the high-profile neighbouring Ramelius Resource Ltd (RMS) and Ordell Minerals Ltd’s (ORD) Barimaia Project to the east. TEM previously completed large-scale auger geochemical sampling program; geological mapping and a 19-hole 1,500m RC drilling program which intersected multiple exciting intervals of gold that include: 3m @ 3.2g/t Au from 58m (including 1m@5.9g/t), 3m@1.9g/t gold from 13m and 2m@1.2g/t Au from 21m. These shallow gold results lie adjacent to existing open pits and less than 10km from the planned Ramelius Resources (ASX:RMS) major processing circuit expansion. No work was undertaken this quarter. Figure 03: Range Project Longitudinal Projection of 2025 drill results Page 3 | 9 ​ ASX : TEM ​ 2026-07-30 | Quarterly Report June 2026 Five Wheels The Five Wheels Project is 266km2 of granted tenure in the Earaheedy region of Western Australia proximal to the high-profile world-class Rumble Resources Ltd (ASX:RTR) discoveries. The project remains largely under-explored (or unexplored for base metals) and shares similar geology to both the nearby Rumble Resources Chinook deposit and the emerging Strickland Metals Ltd (ASX:STR) zinc-lead-copper discoveries. The Project is located in the Earaheedy Basin, where a major geological unconformity surrounding the edge of the basin hosts the initial Rumble Resources discoveries. More recent exploration implies that multiple key geological sequences are or have the potential to be mineralised, and the prospectivity is more widespread than originally considered. No work was undertaken this quarter. Elephant As part of the Company’s ongoing assessment and rationalisation of Projects, during the quarter TEM withdrew from the Elephant Project Joint Venture. New Zealand Following the completion of due diligence, both parties agreed to terminate the previously announced binding Agreement. Other Opportunities Over the next quarter Tempest, in addition to work planned on its existing projects, will continue to identify and pursue other exploration opportunities within the resources sector.
