UPDATE ON Q4 2014 EXPLORATION AT ITOGON GOLD PROJECT
LONDON: 23 DECEMBER 2014 - ECR Minerals plc is pleased to
announce the following results of exploration at the Itogon gold
project in Benguet Province, northern Philippines. ECR is the
operator of Itogon and has the right to earn a 50% interest in the
project.
The final quarter of 2014 saw two phases of channel and grab
sampling completed at Itogon, one underground in artisanal workings
(129 samples for an aggregate channel sampled width of 257.50m) and
one at surface (59 samples for an aggregate channel sampled width
of 101.40m), as well as sampling of muck (ore) from active
artisanal workings (37 samples). Various mapping and surveying
tasks were also completed. Highlights from the assay results
received in respect of Q4 2014 sampling are presented in the table
below.
Stephen Clayson, Chief Executive Officer of ECR, commented:
"The results of ECR's Q4 2014 exploration at Itogon serve to
improve our understanding of the mineralisation in the main
prospect area, and we are encouraged by the assay results reported
in the table below. These include channel sampling intercepts of
wide, low grade zones of gold mineralisation such as 18.0m at
1.02g/t gold in Balao Adit and 10.0m at 1.46g/t gold at MP-71, and
narrower but high grade intercepts such as 5.0m at 10.20g/t gold,
including 1.0m at 43.98g/t gold, in Charlie Adit. Muck samples from
artisanal mining operations are an additional means of locating
high grade zones, and the highest grade muck sample obtained was
68.56g/t gold.
A programme of reconnaissance mapping and sampling had been
planned to commence during October 2014 on ridges to the north-east
and south-west of the main prospect area at Itogon, but was
deferred in favour of the works described in today's announcement,
which were considered more valuable for the purposes of planning
the next drilling programme. Drilling is expected to commence on or
about 15 January 2015 in the main prospect area."

Geological mapping highlighted altered, mineralised and/or
intensely oxidised occurrences for channel sampling, in some cases
following trenching. Channel sampling results are disclosed in the
table above where the weighted average grade exceeds 0.5g/t gold or
the aggregate width exceeds 10.0m. Intercepts are given as apparent
widths. No top or lower cut-off has been applied in calculating
weighted averages. Channel sampling was carried out at intervals of
between 0.5m and 5.0m. Where channels comprised multiple samples,
the table discloses the grades of any individual samples exceeding
2.00g/t gold. Muck samples exceeding 10.00g/t gold are reported
separately in the table.
Assay values have been expressed in this news release as g/t
(grams per tonne) gold but are received from the laboratory
expressed as ppm (parts per million) gold. For the purposes hereof
ppm gold and g/t can be considered equivalent.

announcement may be viewed at:

The maps are for illustration only and should not be relied upon
for technical purposes.
QA/QC
Sampling was carried out under geological supervision. A secure
chain of custody was maintained in the transport and storage of all
samples, which were shipped to and analysed by Intertek Testing
Services Philippines, Inc. ("Intertek"), an internationally
accredited independent analytical laboratory in Metro Manila. Upon
arrival at Intertek samples were sorted, dried, crushed, split, and
a fraction was pulverised. The method of analysis for gold was fire
assay (50g charge) with AAS finish.
QA/QC measures including the use of blanks and standards were
implemented by ECR and separately by Intertek in relation to the
analysis of the samples. The assay data reported is considered
acceptable in the context of these measures.
Review by Competent Person
The contents of this announcement have been reviewed by Andrew
Tunningley MAusIMM (CP), a geologist with the consultancy
Exploration Alliance, which has been engaged by ECR in connection
with the Itogon project.
About the Itogon Project
Exploration by ECR to date, including reverse circulation (RC)
drilling completed in April 2014, indicates that gold
mineralisation in the main prospect area at the Itogon project is
hosted by generally north-west trending, south-west dipping to
subvertical epithermal veins, with a subordinate set of generally
north-east trending veins.
ECR's drilling has confirmed mineralisation over a strike length
of 400m and a vertical extent of 250m, open along strike and down
dip. The width of the overall mineralised zone at surface,
demonstrated by channel sampling, is up to 250m (notwithstanding
sections between vein zones which may be unmineralised).
The epithermal veins are composed of grey and white,
saccharoidal and vuggy quartz with associated clay, calcite,
pyrite, galena, sphalerite, chalcopyrite, and vein breccia, hosted
by moderately to strongly oxidised and argillised medium grained
diorite. Individual veins rarely exceed 1m wide and tend to occur
as approximately 0.2m wide, closely spaced, sheeted veins within
the altered zones. Establishing the continuity of the vein zones
between intercepts at surface, in underground workings and by
drilling is an important exploration objective. The highest gold
grades are typically associated with multiple narrow, 1-2m wide
occurrences of sheeted quartz veins and quartz vein breccia, with a
mineralised selvedge grading approximately 0.30g/t gold or higher
associated with these structures.
ABOUT ECR
ECR is a mineral exploration and development company with, among
other interests, the right to earn a 50% interest in the Itogon
gold project in the Philippines. Itogon is an advanced exploration
project located in a gold and copper mining district in the north
of the Philippines.
ECR has a 100% interest in the SLM gold project in La Rioja
Province, Argentina, the exploration strategy for which is to
delineate multiple medium to high grade, low tonnage deposits
suitable for advancement to production on a relatively low capital,
near term basis.
ECR continues to review potential new investments on a highly
selective basis, with a concentration on precious, base and
strategic metals projects in Asia and South America.
