Lolworth Rock Chip Results & Exploration Update

ECR Minerals plc (LON: ECR), the exploration and development company focused on gold in Australia, is pleased to announce the results of rock chip sampling and trenching activities completed at the Lolworth Project, Queensland, focusing on gold and base metals exploration. ECR also provides an interim update in relation to the diamond drilling programme at its Tambo Gold Project in Victoria.

HIGHLIGHTS

• 378 rock chip samples analysed
• Highest-grade gold results include 11.05, 14.15 and 14.7 g/t Au
• 23 rock chips returned silver grades greater than 10 g/t Ag with six samples exceeding 50 g/t Ag
• Trenching at the Gorge Creek West Prospect has identified broader zones of gold mineralisation, including best grades of 11.05, 3.72 and 4.82 g/t Au within a quartz shear zone
• Newly-discovered gold-bearing veins identified near Gorge Creek West and Uncle Terry prospects

Results (See Tables 1&2)

Gorge Creek West (See Figure 1)

Stream sampling has delineated the ridgeline as a potential gold source, and trenching has revealed a North-South trending quartz sulphide shear zone traced along a 40m strike. A secondary shear was located 12.5 metres west of the main zone. Highlights include:

• Best trenching results: 11.05, 4.82 and 3.45 g/t Au.
• Broader zones of low-grade gold mineralisation (0.2-0.5 g/t Au) found within three metres of the shear zones.
• Reconnaissance rock chips show further potential, with best results of 6.97, 2.59 and 3.72 g/t Au.
• Significant silver mineralisation with best results of 54.4, 50.2 and 24.9 g/t Ag.

An additional shear zone located 350 metres northeast has returned high-grade gold, including 14.7, 14.15 and 8.81 g/t Au. The results indicate that the gold bearing portion of this structure can so far been traced for 40 metres along the surface.

Uncle Terry (see Figure 2)

Reconnaissance rock chip sampling has previously revealed the highest-grade gold assay to date (75.6 g/t Au) from a quartz-sulphide subcrop. Further mapping in the vicinity revealed a quartz-sulphide blow measuring 20 metres x 10 metres at surface. Best results from this quartz blow include:

• Gold assays of 7.59, 6.92, 6.3 and 2.12 g/t Au.
• In addition, high silver values of 78.8, 66.2 and 65.6 g/t Ag have also been discovered. Soil sampling is ongoing to identify potential mineralised extensions.

Geochemical pathfinders

Soil sampling is three-quarters complete, with ongoing analysis aimed at identifying pathfinder elements associated with gold mineralisation. Preliminary results show the following prospect geochemical pathfinders:

• Butterfly Creek: Arsenic and lead
• Dagwood: Weak silver and lead
• Gorge Creek West: Strong lead and silver
• Uncle Terry: Strong lead and zinc with low arsenic.
• Silver-to-gold ratios are highest at Gorge Creek West and Uncle Terry.

Next Steps

A further update on the Lolworth Project will be provided before the end of this calendar year, including management's proposed next exploration steps.

Tambo Drilling Update

The first diamond drill hole has reached 85 metres and encountered quartz and sulphide mineralisation at a 38 metre depth. A second hole is currently underway, with two or three more holes planned for a total planned aggregate depth of 450-550 metres. Further announcements will be made in relation to drilling at Tambo in due course.

Adam Jones, ECR Chief Geologist said: ''These rock chip and trenching results from Lolworth further validate the significant potential that the Board sees in this substantial acreage Project. Not only are we uncovering gold, but we are now seeing significant traces of silver. As previously announced, we believe that there are also exciting prospects for rare earths and other critical minerals and we expect both our own exploration programmes, as well as the recent sampling by the Geological Society of Queensland, will provide us with valuable insights and guide our next steps. The geological resemblance of the Lolworth region to the well-known Charters Towers and Ravenswood goldfields is giving us a glimpse of what may lie within these mountain ranges."
