Multiple visible gold occurrences and pegmatites observed at Lolworth, Queensland
ECR Minerals plc (LON: ECR), the exploration and development company focused on gold in Australia, is pleased to announce the first round of results from the recent stream sediment sampling campaign undertaken at the Lolworth Range project, North Queensland, Australia.
ECR Minerals plc has 100% ownership of three exploration tenements (EPM27901, EPM27902 and EPM27903), which covers the Lolworth Range, located 120km west of the famous gold district of Charters Towers. The project is being explored by ECR’s Australian wholly owned subsidiary Lux Exploration Pty Ltd (“LUX”).
HIGHLIGHTS
- 21 out of 125 stream sediment samples to date are anomalous with gold, with results up to 152.5 ppm Au.
- 18 of the 125 samples show visible gold.
- Further samples are awaiting results including 212 stream sediment samples and 33 rock chips.
- Multiple pegmatites observed throughout the tenements
ECR CEO Andrew Haythorpe commented: “Following today’s placing to raise gross proceeds of £900,000 to further develop our projects, on behalf of the Board I am delighted to report a great start at our Lolworth project, with a highly encouraging 14% visible gold strike rate from the sampling campaign. As we await the results from the remaining samples, we have also incorporated samples from pegmatites observed by our Technical Director on his most recent trip to Lolworth into our plan. These have also been submitted for assay and will be reported at the earliest opportunity. From this we will then move to establish an initial shortlist of targets for further exploration.”
“I look forward to reporting back to you as soon as we receive the results from the remaining samples”

PROJECT OVERVIEW
The Lolworth Range project is located approximately 120km west of the historically famous Charters Towers gold district. ECR Minerals owns three Exploration tenements covering a total area of 964 km2. The area encompasses the Lolworth Range, a region comprising of similar rocks that host world class gold deposits such as Charters Towers and the historic Mt Leyshon Mine (>2.5 million ounces).
In 1987-1988, a stream sediment survey was undertaken by previous explorers ARI Ltd under permit ATP4855M. Their investigations identified numerous anomalous streams within Lolworth Range containing not only visible gold, but also minerals such as tin and tungsten. Research by ECR Minerals geologists established that no follow-up exploration of any note had been undertaken since the work under the ATP4855M permit, mostly likely due to the relatively inhospitable terrain. It is for this reason that ECR Minerals pegged this ground in 2021.
FIRST RESULTS FROM THE STREAM SAMPLING PROGRAM
ECR Minerals has received the results from 125 pan concentrate stream sediment samples which are representative of the first batch of samples submitted to the laboratory in late September 2022. A further 212 samples have been submitted recently with results expected in due course.
Visible gold has been observed in the concentrates of 18 out of the 125 samples (14.4% of the total), which is a better outcome than the results from previous exploration by ARI Ltd. in 1987-88.
All gold results to date have been arranged in increasing order of grade (Au ppm) and analysed by a cumulative probability plot (Figure 1). Results show the presence of five (5) considered gold populations, characterised by the following;
Group 1: Extreme values with a grade range between 5.5 and 152.5 ppm Au.
Group 2: Highly anomalous values with a grade range between 2.1 and 5.5 ppm Au.
Group 3: Mid anomalous values with a grade range between 0.6 and 2.1 ppm Au
Group 4: Low anomalous values with grades ranging between 0.13 and 0.6 ppm Au
Group 5: Considered background values of the surrounding region representing no anomaly with a grade range between 0.00 and 0.13 ppm Au. These represent approximately 83% of all sampling reported.
The ECR board considers samples that fall into groups 1, 2 and 3 to be anomalous in gold. Samples falling within group 4 are a low priority, however some follow-up sampling will be needed as a double check.
The anomalous areas of groups 1, 2 and 3 are notated on the plan map in (Figure 2).
In practice, sampling in the field has shown that not all negative laboratory results correlated with observed visible gold in the panning process. An example is that 8 out of the 89 samples falling into group 5 (background value) were notable for visible gold. This will be taken in consideration for follow up sampling campaigns.

NEXT STEPS
These first results from Lolworth Range lead the Board to believe that the area is highly prospective for gold, increasing both our knowledge of the region and confidence in the overall project potential. The sampling campaign has built considerably on the limited past exploration by ARI Ltd in 1987-88. ECR Technical Director Adam Jones visited the project in early November 2022, and in his field inspection he noted multiple pegmatites throughout the tenements. Previous exploration work had noted Tungsten (W) and Tin (Sn) mineralisation within parts of the region and armed with this knowledge, further analysis is being conducted on all samples to identify potential pathfinders for critical minerals.
There are another 212 stream sediment samples currently being analysed in the laboratory. In addition, 33 rock chips taken from observed mineralised veining at the ‘Uncle Terry’ historical prospect are also being analysed.
