Clarification Announcement

Update to ASX Announcement dated 20 March 2026 “Mount Hope Expands Strategic Cobar Basin Footprint ”

Mount Hope Mining Limited (ASX: MHM ) (“ Mount Hope ” or the “ Company ”) refers to its ASX announcement released on 20 March 2026 titled “Mount Hope Expands Strategic Cobar Basin Footprint” (“Original Announcement”).

The Original Announcement included a reference to the Mt Solitary Exploration Target in the “ About Mount Hope Mining” section. The Company announced the Exploration Target in its ASX announcement released on 10 June 2025 titled “Mt Solitary Gold Exploration Target”.

Mount Hope Expands Strategic Cobar Basin Footprint

Mount Hope Mining Limited (ASX: MHM ) (“ Mount Hope ” or the “ Company ”) is pleased to announce the grant of two new exploration licences, EL9874 and EL9875, further expanding the Company’s landholding in the southern Cobar Basin, New South Wales.

Highlights:

Grant of EL9874 and EL9875 adds approximately 194km[2] of highly prospective ground to Mount Hope Mining’s broader Cobar Basin landholding

The new licences expand Mount Hope Mining’s broader regional footprint in the southern Cobar Basin to approximately 606km²

The new licences secure ground along major regional structures prospective for Cobar-style mineralisation, with EL9875 located along strike from Peel Mining’s Southern Nights – Wagga Tank mineralised trend

Each licence contains early-stage targets generated from historical surface geochemical sampling and has seen only limited historical drilling, providing a strong basis for first-pass modern exploration

Mount Hope Mining Managing Director & CEO Fergus Kiley Commented:

“The grant of EL9874 and EL9875 continues Mount Hope Mining’s strategy of expanding its strategic landholding, adding a further 194km[2] to our broader regional footprint. Importantly, the new tenure captures ground along major regional structural corridors and includes early-stage targets defined from historical surface geochemistry, but with only limited historical drilling completed.

“EL9875 is particularly compelling given its position along strike from the Southern Nights – Wagga Tank trend at the intersection of the Thule & Dusty Tank structures, further demonstrating the prospectivity of this part of the basin.

“We look forward to systematically advancing exploration across both licences through data compilation, geochemical review, geophysics and target generation, to progress the highest-priority targets to drill testing.”

Strategically pegged licences strengthen Mount Hope’s regional footprint

The grant of EL9874 and EL9875 continues the Company’s strategy of building a commanding exploration position in the southern Cobar Basin through opportunistic pegging of prospective ground as it becomes available. EL9874 is located approximately 32 km east-northeast of Mount Hope , while EL9875 is located approximately 42 km north of Mount Hope (Figure 1) .

The Company pegged this ground to secure additional tenure along major Cobar Basin structures (Thule, Kilparney & Woorara faults) that it believes are important to mineralisation (Figure 2). Each licence hosts early-stage targets generated from historical surface geochemical sampling, while historic drilling across both areas appears limited.

In the case of EL9875, the Company considers the licence strategically important given its position along strike from the Southern Nights – Wagga Tank mineralised corridor (Figure 2). Peel’s Southern Nights – Wagga Tank project Mineral Resource comprises 9.99Mt @ 0.35% Cu, 0.41g/t Au, 52g/t Ag, 1.19% Pb and 2.78% Zn[(3)] .

Next steps:

Mount Hope will now advance exploration across EL9874 and EL9875 through a staged programme designed to refine and prioritise targets for drill testing. The next phase of work will focus on further desktop assessment, field mapping and surface sampling, followed by geophysical surveys to better define areas of interest ahead of first-pass drilling. A summary of planned work programmes includes:

• Further desktop review and refinement of priority target areas

• Initial field mapping and surface sampling programmes

• Geophysical surveys to better define prospective zones

• Advancement of highest-priority targets to first-pass drilling, subject to results and access

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 growing ounces and geological confidence at Mt Solitary.

Simultaneously, the Company will be testing and maturing targets along the MS2 corridor, while advancing the highestranked polymetallic targets through staged geophysics, geochemistry and drilling to deliver discoveries and resource growth.

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.
