Mount Hope Mining Managing Director & CEO Fergus Kiley commented:

“The Phase 2 drilling program at Mt Solitary has delivered an excellent set of results and materially advanced our understanding of the system. Standout intercepts, including 6m at 17.9g/t Au from 55m, 17m at 3.2g/t Au from 47m, and 15m at 3.9g/t Au from 102m, demonstrate the continuity and highgrade nature of gold mineralisation at Mt Solitary.

Importantly, this program has done more than return strong grades. It has also expanded the mineralised envelope along strike and down plunge, while providing strong support for our evolving geological and structural model at both the project and regional scales. The results give us increased confidence in the north-west trending controls on mineralisation and have helped define a significant new exploration search space to the south-east of the historic workings.

Mt Solitary continues to grow in scale and significance as a gold target within our broader MS2 Gold Corridor. With planning for our Phase 3 drill program already underway and permits in hand, we are well positioned to continue systematic extensional and infill drilling, while further refining our geological and structural model at Mt Solitary and along the MS2 corridor.”

Mt Solitary Phase 2 drill program

Mount Hope is pleased to report results from its successful Phase 2 Reverse Circulation (RC) drilling program recently completed at the Mt Solitary prospect. The Phase 2 program was designed to test the Company’s evolving geological model and expand the Mt Solitary mineralised envelope.

The Phase 2 program comprised 14 RC holes for 2,161m of drilling (Figure 1). The program was planned to expand the strike extent of the Mt Solitary prospect and test down-dip and plunge extensions to mineralisation observed in the Phase 1 and historical drilling programs.

The result from hole 25MSRC013, which included visible gold and returned 6m at 17.9 g/t Au from 55m , underscores the success of the program and continues to confirm the high-grade nature of the Mt Solitary system.

The program was effective in advancing the strike and dip extent of the mineralised system, with drilling completed to the north and west of the Phase 1 program. This campaign also continues to support the Company’s evolving geological model for the Mt Solitary prospect.

These results reaffirm the prospectivity of the Mt Solitary target while continuing to provide critical information to advance the geological model for the prospect. A list of further significant intercepts can be found in Appendix 1.

Figure 1: Mt Solitary 2025/26 phase 2 RC program

The Phase 2 drilling program at Mt Solitary was designed to test and refine the Company’s evolving geological and structural model for the prospect, following the encouraging results returned from the Phase 1 program. That model interprets gold mineralisation as extending along a north-west trending strike with a corresponding north-westerly plunge. The Phase 2 drill holes successfully intersected gold mineralisation both along strike and down plunge, expanding the mineralised envelope to the current 180m x 220m area.

The Phase 2 program incorporated drilling at the north-western extent of the prospect with holes 25MSRC011 and 25MSRC012 designed to test the interpreted continuation of mineralisation along the projected mineralised plane, and at greater depth than previously drilled in this direction. The result from 25MSRC012, which returned 2m at 15.5g/t Au from 116m , confirmed the presence of high-grade gold mineralisation on the Company’s most north-western drill line to date. Importantly, this intercept is consistent with the Company’s projected mineralised orientation and supports further drilling in the north-western direction, where the system remains open.

The program also tested both the down-dip continuation of mineralisation defined in Phase 1 and the potential for mineralisation to extend to the south-east of the historic workings. Hole 25MSRC013 returned 6m at 17.9g/t Au from 55m with visible gold present in the RC chips (Figure 2), representing the strongest result of the program and confirming the presence of significant gold mineralisation to the south-east of the Phase 1 drilling.

Figure 2: Visible gold with bismite in RC chips from Hole 25MSRC013, 46.2g/t Au from 56-57m

This result is particularly encouraging in the context of the recent CSAMT survey, which indicates that the structures which appear to control mineralisation (MS2 & 320 Northwest structures) converge in the vicinity of the historic workings and project south-east into an area with no previous drilling (Figure 3). This has opened a significant new exploration search space that the Company intends to test as part of a Phase 3 drill program.

Further support for the Company’s structural model was provided by hole 26MSRC015, which returned 17m at 3.2g/t Au from 47m and extended mineralisation down plunge from the Phase 1 program while also indicating a widening of the mineralised envelope in that area. In addition, holes 26MSRC022 and 26MSRC023, drilled down dip of the Phase 1 section, returned 14m at 2.9g/t Au from 161m and 15m at 3.9g/t Au from 102m, respectively (Figure 4). These results extend mineralisation down plunge and provide further support for a steep westerly dip to the mineralised zone, consistent with the Company’s interpretation of the mineralised structure and its relationship to the north-west trending controls identified in the CSAMT survey.

The Phase 2 program has materially advanced the Mt Solitary opportunity by expanding the mineralised envelope, validating the Company’s emerging geological and structural model, and confirming key controls on mineralisation that can now be applied to future targeting both at Mt Solitary and along the MS2 corridor. The drilling has demonstrated continuity of highgrade gold mineralisation along the interpreted north-west trend and down plunge, while also opening a significant new search space to the south-east of the historic workings.

About Mount Hope Mining:

Mount Hope Mining Limited (ASX: MHM ) is an Australian explorer focused on building a strong portfolio of growth assets in the prolific southern Cobar Basin, New South Wales. The Company’s core landholding, the Mount Hope Project , comprises ~606km² in the southern Cobar Basin and is strategically positioned on the eastern margin of the Silurian to early Devonian Mt Hope Trough , straddling the Sugarloaf, MS2 and Scotts Craig basin-bounding fault structures.

Mt Solitary sits within Mount Hope Mining’s expanded MS2 Gold Corridor , a district-scale ~7.5km mineralised trend with multiple targets and strong upside for repeat gold discoveries along strike and at depth.

The Company also holds a broader portfolio of Cobar-style polymetallic (Cu–Au–Ag–Pb–Zn) exploration targets across its 606km[2] landholding.

Mount Hope Mining’s strategy is systematic and drill-led, with an immediate focus on expanding the scale of mineralisation and increasing geological confidence at Mt Solitary. Simultaneously, the Company will continue testing and maturing targets along the MS2 corridor, while advancing the highest-ranked polymetallic targets through staged geophysics, geochemistry and drilling.

The Company’s flagship project is the 100%-owned Mt Solitary Gold prospect , where an Exploration Target has been defined, as set out in Table 1 . The potential quantity and grade of the Exploration Target are conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource, and it is uncertain whether further exploration will result in the estimation of a Mineral Resource. The Exploration Target has been prepared in accordance with the JORC Code (2012).

Table 1: Mt Solitary Exploration Target

Exploration Target	Tonnage (Mt) Range	Au (g/t)	Au (kOz)
Total	1.32 - 1.87	1.0 – 1.35	42.5 – 81.4

Exploration Target basis and proposed work:

The Mt Solitary Exploration Target is based on actual historical exploration results , not on a proposed exploration programme. The target was originally announced by the Company on 10 June 2025[(2)] and is based on drilling completed by previous operators, with the most recent active drill programme conducted in 2017[(2)] . The Exploration Target is based on a 2006 non-JORC compliant resource model prepared by Hellman & Schofield using Multiple Indicator Kriging and incorporates 4,663 composited samples from reverse circulation, percussion and diamond drilling. In total, the Exploration Target incorporates a review of 83 historical drill holes, 4 trenches/costeans and historic production figures. Subsequent drilling completed by Central West Gold and E2 Metals extended the known mineralised system down dip of the 2006 model and demonstrated that the Mt Solitary system remains open at depth[ (2)] . Further detail regarding the geological interpretation, historical drill-hole coverage, supporting plans and sections, and the basis for the Exploration Target is set out in the Company’s ASX announcement dated 10 June 2025 titled “Mt Solitary Gold Exploration Target”.

The tonnage and grade ranges used to describe the Exploration Target were derived from the historical database, previous exploration, the 3D geological model and analysis of the historical information available. All 3D volumes were assigned a specific gravity of 2.5, consistent with the assumptions applied in the historical Hellman & Schofield model. The Company notes that certain historical drill holes completed before 2006 were not subject to rigorous modern QAQC procedures, and some historical downhole survey data is considered unreliable. Accordingly, further drilling is required to verify aspects of the historical dataset and to test the validity of the Exploration Target.

Proposed exploration activities designed to test the validity of the Exploration Target have already commenced and include Phase 1 RC drilling and Phase 2 RC and diamond drilling at Mt Solitary, which were undertaken to begin validating the Exploration Target and refining the geological model. Further work is expected to include additional deeper RC and diamond drilling to test extensions of mineralisation along strike and down dip, together with selected infill and verification drilling of historical mineralised zones. These activities are expected to be completed throughout 2026, subject to approvals, land access and contractor availability. The Company confirms that there has been insufficient exploration to estimate a Mineral Resource, and it is uncertain whether further exploration will result in the estimation of a Mineral Resource.

RC drilling is considered the correct method of sampling for early- stage, near-surface exploration target testing. 1m samples were collected via reverse circulation (RC) drilling using a cyclone splitter. Samples were all dry as the entire drilling program was conducted above the water table. • Sampling and QAQC procedures were developed and carried out by MHM staff. Standards, blanks and duplicates were inserted every 25 meters. Drilling is angled perpendicular to the strike of mineralisation as much as possible to ensure a representative sampling, as reported in this announcement. • Mineralisation in the RC drill chips was geologically logged, magnetic susceptibility readings and pXRF readings were taken on site during the drilling campaign. Reverse circulation drilling was used to obtain 1 m samples from which 1-5kg was pulverised to produce a 50 g charge for fire assay AA-24/AA-26 and four acid ICP analysis, ME-MS61 by ALS Orange Laboratory.

The licence covers an area of Broken Range Group sediments east of the Great Central/Sugar Loaf Fault, which forms a major boundary between the Regina Volcanics and the Broken Range flysch sediments of the Mt Hope Trough. The area covers a series of interpreted subsidiary footwall structures within the Broken Range Group, characterised by topographic highs related to silicification of the sediments along these structures. Using this premise, MHM believes that these footwall structures marked by siliceous sediment could host significant gold mineralisation similar to that of the major deposits found in the northern Cobar Basin and

		those of the Mt Hope Copper Mine located in the footwall of the Sugar Loaf Fault within the Broken Range Group. • The style of mineralisation being explored is a mesothermal shear- hosted deposit analogous to other shear zone-hosted gold deposits in the Cobar region (The Peak and Federation mines). • The Mount Solitary prospect occurs on a small conical-shaped hill to a height of about 100m above the surrounding plain. Gold mineralisation is associated with a broad NNW shear zone of strongly iron-stained, silicified, sericite-altered complex of folded sediments. Alteration is zoned from silica to sericite to chlorite with quartz veins, pyrite and gold. Surface indications of gold lie within an area 250 by 250m. Within the broader mineralised envelope, there is a steepening shoot (from 80-90° NNE to 70-90° SSW) within the “Main Lode” zone and an array of closely spaced, parallel subsidiary lode structures.
