New gold discovery confirmed at Mutsk, Armenia
Orogen Gold plc (AIM:ORE), the AIM quoted gold exploration company, is pleased to report on assay results for its first test diamond drilling programme at the Mutsk gold project in Armenia.
Highlights:
· Orogen confirmatory drill holes return substantially higher gold grades than previously reported
· Assay intervals include 11.0m @ 5.56g/t Au and 10.2m @ 5.73g/t Au
· Mineralised zone confirmed by drilling over almost 1km of strike, with possible extension to 2km+
· Orogen moves into Phase 2 of programme to earn an 80% interest in the property
Ed Slowey, Chief Executive of Orogen, commented: "These results confirm Mutsk as an exciting new gold discovery at shallow depths within an established epithermal district. Assays from the Orogen confirmatory holes at Mutsk, as well as re-assays of the previous holes have exceeded our expectations for the project. While further work is needed to fully understand the controls on mineralisation, we are particularly encouraged by the high grades and widths encountered in several of the holes and the apparently large strike extent of the system.
We have informed our Armenian partners that we will now proceed to Phase 2 of our programme under which Orogen has an option to earn an 80% interest in the Mutsk project by spending a total of US$2.5 million by end August 2016."
Mutsk Project, Armenia
Assay results have been received for all six diamond drill holes of the evaluation programme undertaken by Orogen at the Mutsk Property, as well as re-sampling and re-assaying of drill core from previous short holes drilled by our partner, Georaid CJSC. Initial indications are characteristic of a low-sulphidation epithermal gold-bearing system. Gold grades are considerably higher in some holes compared to previously reported assays (see the announcement dated 22 January 2013), but are consistent with assay results from re-sampling of the original holes which was carried out by Orogen. The original sampling may have understated the grades and widths of the zone as not all drill core was sampled and Orogen applied more rigorous QA/QC over the re-sampling process.
Significant gold-bearing intervals from the Orogen drill programme are summarised in the tables below:

Vertical holes OG13-01 and OG13-02 were drilled on profiles 360m apart to depths of 120.4m and 113.0m respectively along a mapped north-south structural/alteration zone. Please follow this link for the drill plan:
These drill holes 'twinned' two earlier Georaid holes, B-4 and B-5. Four short inclined holes were also drilled by Orogen to help clarify the geometry, structural control and gold distribution of the prospect.
Two of the inclined holes, OG13-03 and OG13-04, were sited near the collars of the vertical holes, while the two remaining inclined holes were located close to Georaid hole B-1 to the south. The vertical holes cut substantially higher grade gold mineralisation than the inclined drillholes. A preliminary interpretation of the results of inclined holes OG13-03 and OG13-04 suggests that they may have cut a more weakly mineralised footwall and a barren hanging wall marginal to the strongly gold mineralised lode intersected in the vertical holes. Hole OG13-05 at the southern end of the prospect missed the lode, while hole OG13-06 intersected a gold and silver-bearing polymetallic vein and anomalous base metal halo previously investigated by a Soviet-era adit. The relationship with the main gold zone will be established as work progresses on mapping and drill testing.
In addition to drilling undertaken by Orogen, re-sampling of a previous Georaid vertical hole B-7, located 260m north of OG13-02 returned an assay interval of 14.0m @ 3.27g/t Au from 22.0 to 36.0m depth. This suggests a minimum strike extent of 600m along the mineralised zone, which is open in both directions. Several short gold intervals, up to 3.0m @ 4.16g/t Au are confirmed by Orogen re-assaying in historic hole B-1 located 330m south of OG13-01. Gold values up to 0.4g/t Au have also been obtained by Orogen from a gossanous bedrock exposure about 1km to the north of the drilled area, suggesting that the mineralised zone may have a total strike extent of at least 2km.
In summary, drilling at Mutsk confirms the discovery of a new gold mineralising system of potential economic importance at shallow depths. While it must be stressed that work on the property is at a very preliminary stage, these initial results are highly encouraging. Detailed geological, litho-geochemical and structural analysis, as well as grid soil sampling is in progress to understand the anatomy of this exciting new project and the controls on the gold mineralisation.
Sampling, Assaying, and Quality Assurance / Quality Control
Recently completed drilling and core sampling work on the Mutsk property has been carried out under Orogen's control. Split core samples were assayed at the ISO 17025 accredited ALS Minerals analytical laboratories in Rosia Montana, Romania and at OMAC Laboratories Ltd, Ireland. QA/QC was ensured throughout the sample handling process and by the insertion of certified standards and blank samples, as well as by in-house laboratory checking.
About the Mutsk Project
The Mutsk Project is located in southern Armenia at about 2,000m elevation and is three hours' drive from the capital Yerevan. The site is accessible most of the year other than during the core winter months. Maps showing the location and details of the project are available on the company's website.
Very limited historic exploration had been carried out until drilling by Georaid in 2011, which intersected low sulphidation epithermal-type pyrite-gold mineralisation in altered and brecciated tuffs, similar in age to those that host the Lydian International high sulphidation Amulsar deposit (2.4 million ounces Measured and Indicated Resources) located 30km to the northwest, also in Armenia.
Orogen has an exclusive agreement with Georaid CJSC to earn an 80% interest in the property by spending a total of US$2.5m by the end of August 2016.

About Orogen Gold
Orogen Gold plc is a UK public company quoted on the London Stock Exchange AIM market (ticker: ORE). The Company's activities are focused on mineral exploration and development in Europe. The Deli Jovan gold exploration district in Serbia is the Company's main operational project. The historic high-grade gold mining camp was last in production prior to World War II and has been significantly under-explored in modern times. The Mutsk gold project in Armenia was optioned by Orogen early in 2013 to follow-up reports of a new epithermal discovery within an established gold district.
