ASX ANNOUNCEMENT

7 October 2025

Major diamond drilling program underway at Western Queen gold-tungsten Project

Key points

• Up to 20,000m of diamond drilling program has commenced primarily targeting high-grade down plunge gold extensions to the Western Queen South and Western Queen Central deposits

• The drilling is being undertaken by DDH1 Drilling, who is supplying two diamond rigs for the program

• The drill program aims to grow the Western Queen gold Mineral Resource Estimate (MRE) of 3.72Mt @ 3.1g/t Au for a total of 370,000 oz Au[1]

• Some of the drilling will also infill the existing Western Queen South MRE of 2.32Mt @ 2.66g/t Au for 198,900 oz[1] with the aim of reclassifying a portion of the Inferred Resources to the Indicated category

• The drilling will also target the high-grade tungsten mineralisation, which occurs as a series of lodes subparallel to the high-grade gold resource and has been identified over a 1,500m strike between the existing Western Queen South and Central open pits

• The aim is to grow and upgrade the recently announced maiden Western Queen Tungsten MRE of 4.31Mt @ 0.31% WO3 for 13.2kt WO3[2 ] which has high-grade tungsten zones within the global mineral resource estimate of 1.44Mt @ 0.51% WO3 for 7.4kt WO3

Peter Harold, Managing Director and CEO commented:

“We are delighted that DDH1 has been able to mobilise a rig so quickly and get this major drill program underway. The program has three main aims which are to:

• discover more gold resources down-plunge of the known resources at both Western Queen South and Central;

• upgrade some of the existing Inferred Resources into the Indicated category; and

• discover more high-grade tungsten resources.

The drilling will also allow us the opportunity to do a geotechnical review of the ground conditions in the vicinity of the proposed portal and decline for the underground.

We look forward to providing shareholders with regular updates on the drilling and assay results as they come to hand.”

Western Queen drilling has commenced

DDH1 Drilling has commenced the diamond drilling program at Western Queen. The planned program is for up to 20,000m of NQ/HQ core drilling. The first rig arrived late last week and commenced drilling on Saturday 4 October. A second rig will be mobilised in mid-October. It is anticipated that the program will be completed by February 2026.

• Objectives of the drilling

• Discover more Gold Resources - The key focus of the drill program is to target high-grade, down plunge extensions to the Western Queen South and Central deposits (refer Figure 2) to grow the Western Queen gold Mineral Resource Estimate (MRE) of 3.72Mt @ 3.1g/t Au for a total of 370,000 oz Au .

1. Upgrade Inferred to Indicated Resources - A small portion of the program will infill the existing Western Queen South MRE which currently stands at 2.32Mt @ 2.66g/t Au for 198,900 oz , with the aim of converting existing Inferred to Indicated Resources ahead of the commencement of mining operations, subject to permitting, ore sales or ore toll milling agreement and all other necessary conditions required for a Financial Investment Decision.

2. Discover more Tungsten Resources – Drilling to discover more high-grade tungsten lodes, which are spatially adjacent, and sub-parallel to, the high-grade gold lodes with the aim of growing the recently announced maiden Western Queen tungsten MRE of 4.31Mt @ 0.31% WO3 for 13.2Kt WO3 at a 0.1% WO3 cut-off which contains a higher-grade portion of 1.44Mt @ 0.51% WO3 for 7.4Kt WO3 at 0.3% WO3 cut off. The drill program will also further assist in developing the understanding of the controls and timing of the tungsten mineralisation at Western Queen and provide critical information that can be applied to the targeting of the tungsten potential at a local and district scale.

3. Geotechnical review - Two holes will be drilled to understand the geotechnical conditions in the area where the underground portal and decline is proposed.

4. Gold recovery confirmation - Selected diamond holes will be used to provide samples for a metallurgical testwork program across both the Western Queen South and Central deposits to validate the previously achieved high gold recoveries of +93% from prior mining operations.

The drill program should provide the basis for a revised Western Queen MRE in early 2026.

About Rumble

Rumble Resources Ltd is an Australian based exploration company, listed on the ASX in July 2011. Rumble was established with the aim of adding significant value to its selected mineral exploration assets and to search for suitable mineral acquisition opportunities in Western Australia.

Rumble has a unique suite of resources projects including the Western Queen Gold Project which is being developed to deliver near term cash flow from the existing resources and is aiming for resource growth through future exploration success. In addition, the discovery of the Earaheedy Zn-Pb-Ag Project has demonstrated the capabilities of the exploration team to find world class orebodies.

The Statement of Estimates of Mineral Resources has been compiled by Mr. Shaun Searle who is a Director of Ashmore Advisory and a Member of the AIG. Mr. Searle has sufficient experience that is relevant to the style of mineralisation and type of deposit under consideration and to the activity that he has undertaken to qualify as a Competent Person as defined in the JORC Code (2012).

All Mineral Resources figures reported in the table above represent estimates as at July 2025. Mineral Resource estimates are not precise calculations, being dependent on the interpretation of limited information on the location, shape and continuity of the occurrence and on the available sampling results.

Mineral Resources are reported in accordance with the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (The Joint Ore Reserves Committee Code – JORC 2012 Edition).

Cranes Mineral Resource figures are derived from the 2024 Mineral Resource estimate.

Open Pit optimisations and preliminary underground Mining Shape Optimisations (MSO) have shown that a large proportion of the resource has the potential to be mined economically, and further mining studies are warranted to further progress the project. Mineral Resources that are not Ore Reserves have not demonstrated economic viability at this point. The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues.
