LONDON: 6 JULY 2015 - The directors of ECR Minerals plc (the “Directors”) are pleased to announce positive results from trenching at the Itogon epithermal gold project, northern Philippines. The trenching was completed during May and June 2015 and comprised 13 trenches totalling 430.6m. Mineralised intervals from the trenching are presented in Table 1 below.

In addition, 12 test pits were excavated in areas too steep or otherwise inaccessible for trenching. Further assay results in respect of various trenches and all test pits are pending.


* Mineralised intervals from trenching (apparent width) include:

60m at 2.43 g/t gold in TR09 (includes interval of 42m at 2.54 g/t gold announced 18 June 2015)
28.6m at 3.61 g/t gold in TR09 (separate and additional to the interval above)
18m at 1.71 g/t gold in TR05
59m at 1.32 g/t gold in TR05
10m at 1.39 g/t gold in TR02

* Very high grades encountered in TR09 including:

1m at 16.74 g/t gold from 10m
1m at 42.29 g/t gold from 28m
1m at 79.67 g/t gold from 84m

Stephen Clayson, Chief Executive Officer of ECR, commented:

“These encouraging results provide further positive indications as to the potential of the supergene enriched oxide gold blanket which occurs from surface in the main prospect area at Itogon, and we look forward to receiving and reporting the remainder of the assay results from the trenching and test pitting programme.

Work at the project during July 2015 is expected to focus on formulating a cohesive geological model for the purposes of the planned resource estimate and accompanying NI43-101 technical report. The Directors anticipate that this report will be completed during September 2015.

This work will include efforts to better understand the controls on the very high grade mineralisation encountered in TR09 and in earlier phases of sampling, as well as in the reverse circulation drilling carried out in 2014.”

Mineralised intervals were calculated as weighted averages using a cut-off grade of 0.30 g/t gold and a maximum of 1m internal dilution. As a result certain reported intervals contain discrete higher grade intervals that are separated by lower grade mineralisation. In these cases the grade of each single sample which exceeded 1.00 g/t gold has been reported separately. No top cut has been applied in calculating mineralised intervals. All widths given in this announcement are apparent width.

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. Sampling was carried out under geological supervision. Upon arrival at Intertek samples were sorted, dried (if necessary), crushed, split and pulverised. The method of analysis for gold was fire assay (50g charge) with AAS finish.

QA/QC measures including the use of certified 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. Assay values have been expressed in this news release as g/t gold but are received from Intertek expressed as ppm gold. For the purposes hereof ppm gold and g/t can be considered equivalent.

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.
