ECR Minerals PLC Identifies New Drill-Ready Gold Target At Butterfly Creek Prospect ECR Minerals PLC announced that laboratory gold assay results from the Butterfly Creek Prospect have identified a compelling new drill-ready gold target within its 100% owned Lolworth Project in North Queensland. Laboratory gold assays delineate a well-defined 200-metre north-northeast trending gold corridor. Peak soil assay of 3,510 ppb Au. Sixteen soil samples returned greater than 100 ppb Au, outlining a well-defined mineralised system. Gold anomaly branches into a second northeast-trending structure associated with quartz outcrop. Results define a compelling follow-up drill target at Butterfly Creek. The first complete laboratory dataset from Butterfly Creek has delineated a well-defined north-northeast trending gold corridor extending over approximately 200 metres, with a peak soil assay of 3,510 ppb Au. The gold anomaly was not detected during earlier portable X-Ray Fluorescence (pXRF) analysis, demonstrating the necessity of laboratory gold analysis as an additional exploration technique to identify gold mineralisation that may not be recognised through conventional pathfinder analysis techniques alone. The Lolworth Project covers approximately 946 km² within the highly prospective Hodgkinson Gold Province of North Queensland and is ECR's largest exploration asset. In December 2025, the Company announced encouraging maiden drilling results from the Uncle Terry and Gorge Creek West Prospects, confirming a gold-silver system and demonstrating the significant exploration potential across the project. Those discoveries originated from a systematic soil sampling programme undertaken between 2023 and 2024. Initial interpretation relied primarily on portable X-Ray Fluorescence (pXRF) analysis to identify pathfinder elements such as lead, arsenic and silver that could indicate nearby gold mineralisation. Whilst this approach successfully identified the mineralisation subsequently drilled at Uncle Terry and Gorge Creek West, pXRF technology cannot directly detect low concentrations of gold. To further evaluate the wider exploration potential of Lolworth, ECR submitted approximately 1,500 soil samples for laboratory fire assay and Inductively Coupled Plasma (ICP) analysis at Onsite Laboratory Services (OSLS) in Bendigo, Victoria. The samples covered both the Butterfly Creek and Uncle Terry Prospects. The Butterfly Creek results announced represent the first complete laboratory dataset received from this programme. A total of 500 soil samples were collected across Butterfly Creek on a systematic 25 metre by 25 metre grid, with selected areas around quartz outcrop infilled to 15 metre spacing. Laboratory analysis has defined a coherent gold anomaly striking north-northeast over approximately 200 metres. The anomaly comprises sixteen soil samples returning greater than 100 ppb Au, including a peak soil assay of 3,510 ppb Au (3.51 ppm). The gold anomaly forms a well-defined north-northeast trending corridor before branching into a second northeast-trending structure associated with a broad quartz outcrop, suggesting strong structural control on mineralisation. The anomalous gold values extend beyond the mapped quartz exposures, indicating the mineralised system has the potential to continue beneath shallow cover. Unlike the Company's previous discoveries at Uncle Terry and Gorge Creek West, the Butterfly Creek gold system displays little correlation with conventional pathfinder elements such as lead or silver. Consequently, the target was not recognised during earlier pXRF surveys and only became apparent following laboratory fire assay. Laboratory gold assays provide an important complementary exploration technique capable of identifying mineralised systems that may not be recognised through conventional pXRF pathfinder analysis alone. Historical metal detector activity along the ridge has also recovered several rich gold-bearing quartz specimens directly above the newly defined gold corridor, providing additional confidence that the surface geochemistry should reflect an underlying bedrock gold system. The Company has commenced planning follow-up exploration, including detailed geological mapping and an initial drill programme in due course to test the newly identified target. Announcement • Jun 11
ECR Minerals plc Completes Drone Lidar Survey And Implements Plant Optimisation Programme At Raglan Gold Project ECR Minerals plc has completed several initiatives in recent weeks which gives it confidence that more consistent gold production and recovery outcomes can be achieved from the project. Drone Lidar survey completed across the Raglan Project area, with data analysis and interpretation now underway to support mine planning, identify additional palaeochannel targets and seeking to enhance future production activities. Independent alluvial gold specialist with more than 30 years' industry experience engaged to review mining and processing operations at Raglan. Plant optimisation programme now in place to enhance gold recovery and operational efficiency. The Company is pleased to confirm that a drone Lidar (Light Detection and Ranging) survey was completed by Victorian Geology and Survey Solutions across the Raglan Project area during May 2026. Processing and interpretation of the survey data is currently underway. The Board believes that the survey has the potential to significantly improve ECR's understanding of historical drainage systems, palaeochannels and mining targets across the project area. The interpreted data is expected to assist future mine planning, identify additional mining opportunities and support production scheduling activities. Mining operations to date have already identified areas with potentially higher gold grades, specifically gullies into the main stream which can act as traps for alluvial gold. The survey therefore forms an important component of the Company's ongoing efforts to optimise mining operations and maximise the broader potential of the Raglan Project. Since acquiring the Raglan Project, the Company has focused on operating the processing plant and mobile mining fleet, establishing mining operations and developing a detailed understanding of the alluvial system. As part of this process, ECR recently engaged an independent alluvial gold specialist with more than 30 years of operational experience in the alluvial mining sector in Australia to undertake a comprehensive review of both Raglan's processing plant and mining methodology. The review identified several adjustments to optimise gold recovery across the processing circuit. These included improvements to gravity recovery systems, water management, jig performance and overall plant calibration. Based on initial analysis, the Board believes that this optimisation programme can increase the recovery potential at the Raglan Project. The independent review also included a detailed assessment of mining operations and interpretation of the alluvial system. Priority target areas have been identified within ECR's existing phase 1 mining plan and activities are now being directed towards these zones which, based on ground analysis, are believed to represent favourable sections of the historical river channel system. In time, the findings from the Lidar data will also be integrated, with a view to further enhancing the operation's efficiency. New Risk • May 28
New major risk - Market cap size The company's market capitalization is less than US$10m. Market cap: UK£7.30m (US$9.80m) This is considered a major risk. Companies with a small market capitalization are most likely businesses that have not yet released a product to market or are simply a very small company without a wide reach. Either way, risk is elevated with these companies because there is a chance the product may not come to fruition or the company's addressable market or demand may not be as large as expected. In addition, if the company's size is the main factor, it is less likely to have many investors and analysts following it and scrutinizing its performance and outlook. Currently, the following risks have been identified for the company: Major Risks Earnings have declined by 1.3% per year over the past 5 years. Shareholders have been substantially diluted in the past year (48% increase in shares outstanding). Revenue is less than US$1m. Market cap is less than US$10m (UK£7.30m market cap, or US$9.80m). Minor Risk Currently unprofitable and not forecast to become profitable next year (UK£1.2m net loss next year).
