ECR Minerals #ECR – Strong new drill results expand alluvial gold footprint at Blue Mountain and visible gold and near-term production potential confirmed
ECR Minerals plc (AIM: ECR), the exploration and development company focused on gold in Australia, is pleased to report a highly encouraging set of alluvial drilling results from its Blue Mountain Project (“Blue Mountain”) in Central Queensland. These drilling results continue to strengthen the case for near-term, low-cost alluvial gold production, with the drilling results confirming visible coarse gold and the expansion of multiple unmined gold-bearing creek flats.
Highlights
· Visible coarse gold recorded in multiple drill samples from the newly identified Upper Kariboe Creek alluvial flat.
· Continuity of mineralisation now mapped across approximately 250 metres of strike, with widths ranging from 6 to 35 metres.
· Grades exceeding the 0.15 g/b.c.m cut-off returned via 19 intersections, including standout results up to 6.52 g/b.c.m, typically indicating the presence of nuggety near-source gold.
· Wash-plant trial work at the Lower Patterson area continues to demonstrate practical mining grades averaging 0.35g/b.c.m, considered favourable to grades in operating alluvial mines across North Queensland.
· Multiple areas now identified as potential start-up gold production zones, including Lower Patterson, Upper Kariboe, Windmill and Roan Colt.
ECR’s Chief Geologist, Adam Jones, commented: “These are some of the most encouraging alluvial results we’ve seen from Blue Mountain to date. Not only have we mapped a continuous gold-bearing corridor across the new Upper Kariboe Creek flat, we are now also consistently seeing visible coarse gold in multiple samples. That is always an exciting moment for a geologist, as coarse, nuggety particles typically indicate that you are close to the source and that the system has real strength.
“Our drilling has delivered far more than we initially expected. We set out to understand the gold trail and the host gravels, but the results are now giving us a clear picture of multiple unmined zones that have the potentiual to translate into a near-term alluvial production opportunity. The combination of strong drill grades, visible gold and the successful wash-plant trials at Lower Patterson is building genuine confidence that Blue Mountain has the scale and quality to support a commercially viable start-up operation.”
Summary of Drilling Program
A total of 264 shallow drill holes were completed in August 2025 across the Upper Kariboe and Denny Gully areas. The objective was to identify shallow, mineable alluvial gold deposits suitable for cost-efficient production.
Each hole was drilled from surface to bedrock, with samples collected every metre and assessed for gold content, material type and the presence of visible gold. Concentrated gravel samples were fire-assayed at On-Site Laboratory Services in Bendigo, and gold recovered was used to estimate grammes of gold per bank cubic metre (b.c.m) – which is considered to be the industry standard measure for alluvial mining viability.
Inevitably, gold particle size and distribution varies in alluvial systems, but the drilling campaign has provided a clear, reliable picture of the gold trail, allowing ECR to identify high-priority potential production zones with growing confidence.
Latest Drill Results
These results come from a previously untested, unmined creek flat at Upper Kariboe Creek (See Table 1 and Figure 1). This area is now emerging as one of the strongest alluvial targets in the project to date and, as a consequence, represents a further potential extension of the potential production zones in the project area.
Key outcomes:
· 19 samples above the 0.15 g/b.c.m cut-off, ranging from 0.16 g/b.c.m up to 6.52 g/b.c.m
· Multiple high-grade intersections contain coarse, nuggety gold, suggesting proximity to a primary source
· Mineralisation appears to form a continuous, mineable corridor approximately 230 metres long, with widths between 6 – 35 metres
· This is the first area where ECR has confirmed larger visible gold particles, representing a significant step forward in confidence

Wash Plant Trials (Lower Patterson)
To validate drill grades under more real-world conditions, four bulk samples were run through a trial wash plant at Lower Patterson (See Table 2 and Figure 2). These tests simulated future production and confirmed highly recoverable gold values.
Key results:
· Average trial grade: 0.35 g/b.c.m
· Consistent recovery across all samples, including those taken from drill-defined zones
· Coarse gold observed during processing
· Trial grades are considered favourable to third-party established alluvial operations currently running across North Queensland
Taken together, the drilling and wash-plant outcomes reinforce Lower Patterson as a commercially attractive start-up mining area, with potential for near-term development.

Peripheral Drilling – Expansion of Target Area
Drill traverses at Windmill, Roan Colt and upper Dennys Gully have been completed, with further assay results pending in due course. Visible gold was noted during the preparation of several samples, and management anticipates that these areas may further increase the overall footprint with potential for near-term development. Of particular significance is drilling west of the original Lower Patterson flat.
Many of these peripheral areas show no evidence of historic mining, meaning ECR is the first to systematically test and map their gold potential.

ECR Minerals #ECR – November Operations update
ECR Minerals plc (AIM: ECR), the exploration and development company focused on gold in Australia, is pleased to provide an update on the next steps following the successful conclusion of its 2025 drilling programme at the Lolworth Gold and Rare Earths Project (“Lolworth”) and the Blue Mountain Project (“Blue Mountain”) in Queensland, together with a wider update on progress in respect of its other operations and recent activities.
The Company’s operational focus continues to centre on establishing near-term production at its advanced-stage Queensland alluvial gold projects, while seeking to unlock the large-scale discovery potential across its broader tenement package in one of Australia’s most prospective gold provinces.
Highlights
- Assay results from drilling at Lolworth and Blue Mountain are expected this month.
- Visual indicators from wash plant trials at Blue Mountain support plans for commercial production.
- Legal documentation for proposed acquisition of the Raglan Project are well advanced, with discussions with production partners underway.
- Creswick JV (defined below) discussions ongoing and the ECR board are assessing opportunities for other tenements.
Queensland drilling programme
During July and August, ECR drilled almost 400 holes across the Lower Patterson, Windmill and Upper Kariboe Creek areas at Blue Mountain using a reverse circulation drilling rig. Visible gold has been confirmed in multiple zones and preliminary results were announced on 15 September 2025 confirming extensive gold mineralisation in the Lower Patterson area. Samples from the remaining holes have been sent for assay and results are expected this month.
The rig then moved to Lolworth where ECR drilled 21 holes at the Uncle Terry prospect and a further seven holes at the Gorge Creek West prospect, to depths of between 30 and 42 metres, during September. Drill samples have now been packaged and recorded and are also with the laboratory for assay.
Following completion of activities at Lolworth, the ECR team returned to Blue Mountain where several wash plant trials were conducted to determine the likely gold recovery. The trials were conducted over both high and low grade material and preliminary observations based on visible gold have been encouraging.
As previously announced, the distribution of gold particles within the alluvial gravels at Blue Mountain is not yet fully known. Drill samples are small volumes of material and so, whilst drill results are indicative of the location of gold and therefore where mining may in the future take place, they are not suitable for resource estimation or for providing a definitive indication of grade. The wash plant trials are conducted with bulk samples which are designed to determine a more representative gold content and potential recovery rate. Interestingly, and based on visible analysis, results appear to be better in the lower grade material areas. This supports ECR’s theory that there is an element of coarse gold at Blue Mountain which cannot always be reliably picked up from drill samples.
Further analysis of the wash plant samples is currently being conducted.
Although several results are outstanding, the information to date supports ECR’s belief in respect of the commercial opportunity at Blue Mountain. Once all the results are available, ECR intends to submit a mining lease application in the fourth quarter of 2025, as the next step towards production at Blue Mountain and cashflow generation.
Raglan Project – Near-Term Production of Alluvial Gold
As announced on 1 October 2025 and 17 October 2025, ECR is proposing to acquire Raglan Resources Pty Ltd (the “Proposed Acquisition”), the holder of Licence ML 3665 (the “Raglan Project”) for A$1.01 million. The purchase price is fully funded by the subscription announced on 1 October 2025. Legal documentation is now very advanced and subject only to comments from the vendors’ lawyers. All due diligence questions have also been submitted and, to date, the information supplied has been in line with ECR’s expectations. As such, ECR anticipates completing the Proposed Acquisition this month.
Pending anticipated completion of the Proposed Acquisition, ECR has also begun discussions with a potential production team, the aim being to ensure that gold production at the Raglan Project can begin within a relatively short time thereafter.
There can be no certainty that final binding terms will be agreed in order to complete the Proposed Acquisition, nor as to the timing or final terms, value or conditions of the Proposed Acquisition. Further updates will be provided in due course.
Other tenements
On 18 September 2025, ECR announced that it had entered into a non-binding heads of terms with Exertis Pty Ltd trading as Bold Gold (“Bold Gold”) for a proposed joint venture (the “Creswick JV”) covering the Company’s Creswick Gold Project in Victoria, Australia. Discussions remain ongoing.
The Company is also undertaking a review of its portfolio including tenements that have received less focus. We consider that it has long been a strength of ECR that it holds an extensive and diverse portfolio but, with the near-term production and revenue opportunities in Queensland, the board of directors is assessing future operations to ensure it gets the best value out of all projects without diverting from its core strategic objectives. In this regard, and by way of example, the Company is assessing an approach for a possible joint venture over another of its tenements. This discussion is at a very early stage but is illustrative of the board’s plans for the future. The Company operates with a small team and the objective is to ensure that they are able to focus on the highest impact projects. ECR expects to develop its work programme for 2026 shortly, although it will be no surprise to investors that it will be dominated by the Queensland projects.
ECR Chairman Nick Tulloch added: “It may have been relatively quiet on the news front for ECR in the past few weeks but, behind the scenes, it has been a very busy period for us. All samples from the Queensland drilling campaigns are now in the laboratory for analysis, as are the outputs from the wash plant trials at Blue Mountain. The administrative tasks of preparing to produce gold, initially at Raglan once this Proposed Acquisition has been completed and then nearby at Blue Mountain, are also well advanced.
“We believe that ECR is undergoing a transformation from explorer to producer and these forthcoming assay results will shape our plans in this regard at Blue Mountain. Meanwhile we continue to work towards the conclusion of our Proposed Acquisition of the Raglan project where we anticipate commencing production relatively quickly after completion.
“This repositioning of our strategy over the last year naturally requires an assessment of portfolio. We operate with a small team and, as we concentrate on alluvial gold production, we will ensure that we continue to build value in our other projects. These plans will develop over the coming months and I will look forward to updating shareholders during that period.”
