Tambo Gold Project Diamond Drilling Update

ECR Minerals plc (LON: ECR), the exploration and development company focused on gold in Australia, is pleased to announce an update on drilling at the Duke of Cornwall prospect within the Company's Tambo Gold Project in Victoria, Australia (the "Tambo Gold Project") where results have been received for an additional 90 core samples submitted from diamond drill holes DOCD003 and DOCD004.

HIGHLIGHTS

●    Best results from hole DOCD004 include 0.15 metres @ 10.6 g/t Au, 0.35 metres @ 1.47 g/t Au and 0.15 metres @ 1.42 g/t Au

●     DOCD004 successfully intercepts Main Lode at a depth of 62.3 metres

●     Hole DOCD003 delineates shear zone's location

Tambo Gold Project

As announced on 20 November 2024, a maiden diamond drilling campaign was completed at the Tambo Gold Project. The diamond drilling campaign targeted beneath the historic workings of the Duke of Cornwall Mine, Swifts Creek. The campaign consisted of five diamond core drill holes, totalling approximately 439 metres in aggregate.

Drilling Programme Overview

Drilling at the Project's Duke of Cornwall prospect aimed to demonstrate grade continuity and refine initial geological interpretations. Results to date confirm that these objectives have been achieved, with diamond drilling providing high-accuracy structural and mineralisation data.

·      Main Lode Gold Continuity: Results from DOCD002 (0.4 metres @ 8.51 g/t Au) and DOCD004 confirm vertical gold continuity extending at least 70 metres below the Adit workings.

·      Historical Continuity: Historical records report average grades of approximately 10 g/t Au from lodes up to 4 metres wide. Several of the best drilling results to date closely align with this average (see Table 1 and Table 2 of highlighted recent results below).

Geological mapping and structural data suggest potential for high-grade zones where cleavage veins intersect the Main Lode. These intersections may represent historical wider lode sections.

Drill hole DOCD004 (see Table 1)

Hole DOCD004 was drilled to test for grade continuity vertically below previous high-grade results obtained from the Adit workings and DOCD002. The target Main Lode was successfully intercepted at a depth of 62.3 metres with gold values of 0.15 metres @ 10.6 g/t Au. This hole was drilled to a final depth of 86.4 metres. Two additional intercepts of 0.15 metres @ 1.42 g/t and 0.35 metres @ 1.47 g/t Au were from two distinct quartz veins located in the footwall and hanging wall of the Main Lode. The Board believes that these two veins show the potential for the development of undiscovered veins within the system. The overall average grade across all reported intervals was 4.50 g/t Au (see Table 1).

Drill hole DOCD003

No significant gold intercepts have been reported from the intervals tested from drill hole DOCD003, although the Board considers that this result provides valuable geological insights into delineating the location of the shear zone and controls on mineralisation.  Hole DOCD003 was drilled to a total depth of 69.7 metres.

Next Steps

The Company is awaiting the assay results from drill hole DOCD005 which was designed to test for mineralisation under the extreme northern strike of the system and also for drill hole DOCD001. Results for both remaining holes are expected before the end of the year. Geological logging of DOCD005 thus far has identified two distinct quartz veins, aligning with historical reports of similar lodes. 

Adam Jones, ECR's Chief Geologist, said: "The results from drill hole DOCD004 mark another positive step forward in our exploration of the Duke of Cornwall prospect. While DOCD003 provides valuable geological insights into the location of the shear zone, DOCD004 has confirmed gold continuity within the Main Lode and highlights the potential for additional undiscovered veins within the system. I'm highly encouraged by how the best findings from DOCD002 and DOCD004 match up with historical records and the Board is optimistic about the potential for high-grade gold mineralisation as we continue to explore the strike and depth of the system. We eagerly await the assay results from DOCD005, which will provide further insight into the mineralisation potential at the northern end of the Duke of Cornwall system.''

Technical Disclosure

All sampling and drilling were conducted in accordance with industry best practice, and all assays were performed by an independent, accredited laboratory.
