STRONG ANTIMONY GRADES AND GOLD RESULTS CONTINUE IN NSW WITH US EXPLORATION TO COMMENCE
HIGHLIGHTS
-
Rock chip sampling of outcropping mineralisation at the Oaky Creek prospect, part of the Armidale Antimony-Gold Project returned further strong results highlighted by:
-
36.3% Sb at Oaky Creek North
-
18.8% Sb at Oaky Creek North
-
23.0% Sb and 0.36g/t Au at Oaky Creek South
-
Initial rock chip sampling at the previously unsampled East Hills prospect in the south of EL9372 returned a best result of 9.9% Sb, with anomalous samples collected over a strike extent of 70m
-
Initial rock chip sampling of the nearby historical Horsley Station gold workings returned up to 0.25g/t Au and evidence of ultramafic lithologies, a preferred host for gold mineralisation along the Peel Fault
-
’
-
The strong spatial correlation between Antimony and Gold supports RMX s exploration model for the Oaky Creek prospect, targeting a vein-style orogenic antimony-gold deposit, which is considered analogous to Larvotto Resources’ (ASX: LRV) Hillgrove project, Australia’s largest Antimony deposit
-
Evidence of Antimony and Gold mineralisation from multiple prospects across the length of the project highlights the strong potential of the tenement to host multiple orogenic antimony-gold systems associated with the Peel Fault system and its related splays
-
The Armidale Antimony-Gold Project comprises a large, strategic tenure covering nearly 400km[2] of highly prospective ground, west of Larvotto (ASX: LRV) ($550m market cap)
-
RMX well positioned to leverage increased Australian and US Government interest in critical minerals, with Utah Antimony Project exploration set to commence
-
Red Mountain continues to assess value accretive critical metals assets in the United States and is progressing its US Stock Market listing, given the significant interest globally in the Company’s projects

Red Mountain Mining Limited (ASX: RMX; “ RMX ” or “ the Company ” ), a gold and critical minerals exploration and development company with a focus on the United States and Australia, is pleased to announce additional rock chip analyses for samples collected at three prospects within the Company’s 100% owned Armidale antimony-gold project (EL9732) in the Southern New England Orogen of northeast New South Wales.
Analytical results of up to 36.3% Sb and 0.36g/t Au have been received for additional rock chip samples from the Oaky Creek prospect in the northern portion of RMX's tenement (Figure 1), where the company previously reported antimony in soils results of up to 333ppm Sb[1] and rock chip values of up to 39.3% Sb and 1.09g/t Au[2] . RMX has also collected its initial rock chip samples from the southern portion of the project area (Figure 1), with 20 samples analysed from the previously unsampled East Hills antimony prospect, with a best result of 9.9% Sb , and eight rock chip samples from the Horsley Station gold prospect recording up 0.25g/t Au .
Further strong results for Oaky Creek
Rock chip sampling at Oaky Creek North and Oaky Creek South was undertaken during the collection of approximately 250 hand auger soil samples spaced at 10m and 20m across the Oaky Creek South prospect (Figures 2 and 3), following up antimony soil anomalies defined by initial 50m x 100m spaced soil sampling reported in June 2025. Analytical results for the hand auger sampling program are expected to be received before the end of October.
Rock chip samples were analysed at Intertek’s Townsville laboratory for Sb, Ag, As and W using sodium peroxide fusion and ICP-MS finish, and for Au using a 50g fire assay charge and ICP-OES finish. All analytical results are listed in Appendix 1, and gold and antimony results are shown in Figures 2 and 3.
Eight new samples were collected from the Oaky Creek North area, from both the immediate surroundings of the historical workings and from the antimony bearing creek exposure ~500m northnorthwest of the workings. Five of these samples were found to contain >1% Sb (Figure 2B), with a best value of 36.3% Sb , which is the highest antimony result recorded to date for Oaky Creek North.

A sample of weathered outcrop or subcrop (AAR189, Appendix 1) collected ~500m northwest of the Oaky Creek South workings contains 23.0% Sb and 0.36g/t Au. This sample is located within 6m of two float samples that were reported on 2 October[3] to contain 39.3% Sb and 0.16g/t Au, and 33.5% Sb and 1.09g/t Au, respectively (Figures 2C and 3C). The close proximity of in situ mineralisation to the mineralised float samples supports RMX’s previous interpretation that the float was collected close to source.

Antimony-mineralisation confirmed at East Hills
As previously reported, RMX has also completed initial soil sampling over the East Hills antimony prospect in the southern portion of EL9732. Results are anticipated before the end of October for a total of 78 soil samples that were collected on a 50m x 100m spaced grid centred on the historical workings at the prospect (Figure 4). During this program, the company also collected 20 rock chip samples over the prospect (Appendix 1) and confirmed the presence of high-grade antimony mineralisation, with a best result of 9.9% Sb (Figure 4). A further two samples with anomalous (>500ppm) antimony were collected ~70m north-northwest along strike from the mineralised sample, indicating that antimony mineralisation at East Hills extends well beyond the small historical workings. Gold analyses for all samples were low, with a best result of 0.016g/t Au (Appendix 1).

Anomalous gold and prospective ultramafic host rocks confirmed at Horsley Station
RMX collected eight rock chip samples from the historical workings and nearby outcrops at Horsley Station. A sample of quartz-fuchsite vein material from the workings returned an anomalous gold value of 0.25g/t Au, while a nearby sample of similar material contained anomalous antimony of 0.18% (Figure 5). An outcrop of ultramafic rock was also sampled ~25m east of the workings (Figure 5). Although this sample is not mineralised, ultramafic lithologies are recognised as the preferred host for gold mineralisation along the Peel Fault system and the exposure supports RMX’s interpretation that magnetic highs at Horsley Station and Horsley North (Figure 1) represent structurally bound ultramafic bodies.

Next steps for the Armidale Antimony-Gold Project
Subject to positive results for the pending assays from Oaky Creek South, RMX will undertake a similar program of soil and rock chip sampling over the Oaky Creek North soil anomaly to define prospective drill targets. Further work is also anticipated at East Hills to follow up the initial positive antimony rock chip results, with next steps to be finalised following receipt and interpretation of the results of the soil sampling program.
As previously reported[4,] , soil and rock chip sampling is also planned for the Horsley Station and Horsley North gold targets, where land access has now been secured. As reported in August 2025[5] , RMX is also working to secure land access to ground truth stibnite and jarosite spectral anomalies across EL9732, in particular those that lie adjacent to known mineralisation and/or are along the known major Peel, Namoi and Cobbadah faults.
RMX well positioned to leverage increased Australian and US Government interest in critical minerals
Presently, about 90% of global antimony production is controlled by China, Russia, and Tajikistan, which is creating significant supply risks for Western nations such as Australia and the US, where it the metal is a critical component for armament manufacture. With China’s export ban creating acute supply shortages and antimony prices recently reaching US$60,000 per tonne, the US Government has issued emergency declarations and mobilised unprecedented funding for domestic production.
RMX has responded to this opportunity through the acquisition of three highly prospective antimonygold projects in Utah[6] and Idaho[7, 8] , USA. Following a recent successful $1.5M placement[7] , the Company is well funded and intends to apply the funds raised to accelerate exploration and development across its U.S. Critical Minerals and Australian gold–antimony projects, with exploration at the Utah Antimony Project set to commence.

RMX Armidale Antimony-Gold Project Background
RMX’s 100%-owned Armidale antimony-gold project (EL9372) lies approximately 85km west of Australia’s largest known antimony deposit, Larvotto’s (ASX: LRV) Hillgrove deposit, which is also the 8[th] largest antimony deposit globally.
LRV recently announced that plant upgrade works have commenced at Hillgrove[9] . Plant construction is expected to be completed by the end of Quarter 2, 2026. At full capacity, Hillgrove is expected to deliver 40,500 ounces of gold and 4,878 tonnes of antimony, annually, making it a globally significant antimony producer.
The Southern New England Orogen is recognised as Australia’s premier Antimony province (Figure 6). Antimony occurs in hydrothermal quartz veins, breccias and stockworks, often with associated gold and/or tungsten mineralisation.

EL9732 extends for 85km along the western side of the Peel Fault. The geology of the project area is dominated by isoclinally folded Carboniferous metasediments of the Tamworth Belt, which is a forearc basinal package related to west-dipping subduction of oceanic crust beneath the Lachlan Orogen. Ultramafic mélanges of the Great Serpentinite Belt, which outcrop along the Peel Fault, are considered to be remnants of this oceanic crust. The Peel Fault System has recognised world-class mineral potential, with over 400 known orogenic gold and base metal mineral occurrences along its over 400km strike extent, but is underexplored, with less than 200 mostly shallow drillholes over its length, the majority of which are focused on discrete prospects.

JORC Code, 2012 Edition - Table 1
1.1 Section 1 Sampling Techniques and Data
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Sampling techniques |
• Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • Aspects of the determination of mineralisation that are Material to the Public Report. • In cases where ‘industry standard’ work has been done this would be relatively simple (eg ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information. |
• Rock samples were collected from 1kg grab samples. • Rock chip samples were selective based on visual appearance and are not used for resource determination, only to check if mineralisation is present. • All samples are exploration in nature and not for resource determination. • Rock, auger & Soil samples have been sent to Intertek Townsville laboratory with the auger and soils forwarded on to the Perth Laboratory. • Rock samples were assayed by sodium peroxide fusion FP6/OM for Sb, Ag, As and W with an ICP_MS finish Au was analysed by 50g lead fire assay with an ICP-OES finish (FA50/OEO2) where rock samples were analysed at the Townsville facility. • Auger and Soil samples will be treated by Aqua regia digest with a 25g charge assayed by ICP-MS for a 52-element suite. • All auger samples were collected on 10 to 20m spaced grids or single traverses at 25m. Soils were collected. • d on a 50m centred grid. • Auger samples targeted the C soil horizon usually at 20-100cm depth while soil horizons targeted the B soil horizon averaging15cm |
| Drilling techniques |
• Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details |

| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Mineral tenement and land tenure status |
• Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. • The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area. |
• The Exploration licence EL9732 is granted and 100% wholly owned by Red Mountain Mining and covers 391km2. • The licence is predominantly in Freehold pastoral properties and as such Native Title is extinguished. |
| Exploration done by other parties |
• Acknowledgment and appraisal of exploration by other parties. |
• The north-south elongate corridor covered by the project contains no historical mineral exploration drilling and has seen limited previous surface exploration for Antimony and Gold mineralisation. No soil sampling for these elements has been undertaken and rockchip and stream sediment coverage is limited, leaving the majority of the tenement untested by systematic exploration and therefore is considered having significant potential for discovery. • Icon Resources Ltd conducted exploration over there Dunmore target, Baldwin project EL6682 in 2008, data taken from the open file reports at NSW Resources. |
| Geology | • Deposit type, geological setting and style of mineralisation. |
• The project is located in the Southern New England Orogen. The geology of the tenement is dominated by isoclinally folded Carboniferous metasediments of the Tamworth Belt which is a forearc basin package related to west-dipping subduction of oceanic crust beneath the Lachlan Orogen. Ultramafic melanges of the Great Serpentinite Belt, which outcrop |

| Drill hole Information |
• A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: o easting and northing of the drillhole collar o elevation or RL (Reduced Level –elevation above sea level in metres) of the drill hole collar o dip and azimuth of the holeo down hole length and interceptiondepth o hole length.• If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain whythis is the case. |
• No drilling conducted |
| Data aggregation methods |
• In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually Material and should be stated. • Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation |
• No aggregated methods are reported |

| should be stated and some typical examples of such aggregations should be shown in detail. • The assumptions used for any reporting of metal equivalent values should be clearlystated. |
||
| Relationship between mineralisation widths and intercept lengths |
• These relationships are particularly important in the reporting of Exploration Results. • If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. • If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (e.g. ‘down hole length, true width not known’). |
• No relationship is made between mineralisation width and intercept lengths |
| Diagrams | • Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. |
• Appropriate location diagram is presented in the text. The diagram is indicative only as no assumptions of grade, extent or depth are made. |
| Balanced reporting |
• Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reportingof Exploration Results. |
• Only pertinent results are given as due to the relevance of the announcement. |
| Other substantive exploration data |
• Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics;potential |
• There is no other substantive exploration data provided or withheld as this announcement deals with this early phase exploration target. |
