Extensive zones of gold mineralisation confirmed in early drilling at Blue Mountain

 

ECR Minerals plc (AIM: ECR), the gold exploration and development company
focused on Australia, announces the first set of gold results from drill
sampling at the Lower Patterson area within the Blue Mountain gold project,
Queensland, Australia (the "Blue Mountain Project").

 
HIGHLIGHTS

·      Initial drilling results confirm extensive zones of consistent
gold mineralisation at the Lower Patterson prospect - an area not previously
mined.

·      Peak results include 1m estimated @ 1.14 g per b.c.m and 1m
estimated @ 1.07 g per b.c.m.

·      17 samples estimated above 0.15 g per b.c.m demonstrating wide
continuity across three drilled sections.

·      Results highlight the increasing scale and potential of the
gold-bearing gravels at the Blue Mountain Project - particularly as new areas
of gold mineralisation are identified.

 
Sampling Programme

An initial programme of vertical reverse circulation drill hole traverses was
completed at the Blue Mountain Project in the Lower Patterson area (see Figure
1). Five traverses were drilled, consisting of 36 holes, each having an
individual depth ranging from approximately 5 to 12 metres, with a total
combined depth of 291 metres.  Samples were collected at one-metre intervals
from surface to basement contact, with each 115 mm-diameter sample
representing approximately 10 kg in 0.01 cubic metres of material. The purpose
of this type of drilling is not to recover a representative sample in alluvial
terrains but to confirm the presence of gold (visually) followed up by assays
to detect very fine-grained gold. Assay results are only indicative of gold
content.

 

Each sample was panned down to a representative concentrate of around 100
grammes. Visible gold was logged and visually estimated. Concentrate samples
were then analysed at OSLS-Bendigo for total gold content, reported in
milligrams per sample. Results were converted to an estimated bank cubic metre
(b.c.m) equivalent to using a factor of 96.27 samples per b.c.m.

 

The strongest mineralised intervals (≥0.15 g per b.c.m) were recorded in
three drill sections, including total aggregated widths of 66 metres in
Section 1, 11 metres in Section 2, and 81 metres across four zones in Section
3. These results are considered to highlight the very extensive scale of
gold-bearing gravels within the Lower Patterson area (See Figure 1).

 

The objective of this initial drill programme was to map out the extent and
scale of the mineralised alluvial zones. Based on the results received, the
exercise is considered by management to have been highly successful.  Noting
that the Lower Patterson area has not previously been mined, this represents a
potential extension of the Blue Mountain Project.  Furthermore, the current
gold price levels and the shallow depths at Blue Mountain may create further
extension possibilities as lower cut off grades may now be economic.

 

The distribution of gold particles within the alluvial gravels at the Blue
Mountain Project is currently not fully known. As drill samples represent
small volumes of material, these initial results cannot be used for resource
estimation or provide a definitive indication of grade variability until other
work has been performed, including follow-up wash plant trials which are
designed to determine the true gold content and potentially verify the
drilling grades.

Next Steps

Ø ECR has drilled two other similar-sized creek flats at the Blue Mountain
Project, namely the Denny's Creek and Upper Kariboe areas, with results
expected likely in October.

Ø The Company has received external interest in potential production
partnerships, with preliminary discussions now in progress. There can,
however, be no guarantee as to the conclusion of any such discussions, nor as
to the timing or terms, structure or value of any such production partnership.

 
Blue Mountain Gold Project

The Blue Mountain Gold Project is located in North Queensland within the
historic goldfields of the region. The Blue Mountain Project area hosts
extensive alluvial workings along the Kariboe Creek and its tributaries, much
of which was only partially exploited by historic operators. The Board
believes that ECR is the first company to undertake a modern systematic
drilling programme across these alluvial channels, providing detailed
information on gold distribution within the gravels.

 

With large volumes of alluvial material present, the Blue Mountain Project
offers both near-term production potential and longer-term exploration upside,
as the Company continues to assess the broader extent of gold mineralisation
across the Blue Mountain Project.

 

Nick Tulloch, ECR's Chairman commented: "These first results from drill sampling at the Lower Patterson area have exceeded our expectations. They demonstrate consistent gold occurrences across wide zones and provide a strong foundation as we continue our programme. The objective of this work was to define the extent of gold-bearing channels, rather than just indicative grade points, and in this respect the results are very encouraging. This is particularly pleasing in areas that have apparently not been mined before, as we are potentially augmenting the alluvial resource inventory on the property. We await the results from the Denny's Creek and Upper Kariboe areas and, with the success of what we are seeing, it is perhaps no surprise that we have attracted interest from potential partners who recognise the potential commercial production opportunity at the Blue Mountain Project. We look forward to providing further updates as results and discussions progress."

Ltd ("ECR Australia") and ECR Minerals (Queensland) Pty Ltd ("ECR
Queensland").

 

ECR Australia owns the Bailieston and Creswick gold projects in central
Victoria, Australia as well as the Tambo gold project in eastern Victoria.

 

ECR Queensland has two approved exploration permits over the Blue Mountain
alluvial gold project in central Queensland, Australia, which it is currently
working to bring into production.  It also has three approved exploration
permits covering 946 km(2) over a relatively unexplored area in Lolworth Range
in northern Queensland. Furthermore, ECR Queensland has also submitted a
licence application at Kondaparinga which is approximately 120km(2) in area

Queensland.

 

Following the sale of the Avoca, Moormbool and Timor gold projects in
Victoria, Australia to Fosterville South Exploration Ltd (TSX-V: FSX) and the
subsequent spin-out of the Avoca and Timor projects to Leviathan Gold Ltd
(TSX-V: LVX), ECR Australia has the right to receive up to A$2 million in
payments subject to future resource estimation or production from these
