Orsu Metals Corporation ("Orsu" or the "Company") (TSX:OSU)(AIM:OSU), the London-based base and precious metals exploration and development company, is pleased to announce that the Company has received all final assay results for the 2014 scout drilling programme at its Kogodai volcanogenic massive sulphide copper prospect in northeast Kazakhstan (the "Kogodai Prospect"). The Kogodai Prospect is effectively 51% owned by Orsu and is not currently considered to be a material property.

The Kogodai Prospect is located approximately 70 km north west of the Company's Karchiga Project in Kazakhstan. It shares similar geological characteristics with Karchiga, including similar metamorphic stratigraphy, consisting of sandwiched amphibolite and gneiss.

In October to early November 2014, Orsu drilled five scout diamond drillholes totalling 457 m. The main objective of this drilling programme was to assess the style and quality of mineralisation. The metamorphosed volcanogenic disseminated to semi-massive sulphide mineralisation at the Kogodai Prospect is controlled by the lithological contacts between gneiss and amphibolite layers at several stratigraphic levels within the metamorphic sequence. Near surface, sulphides are oxidised to a depth of approximately 30 m.

The mineralised zone was traced during Soviet times in the >0.1% Cu geochemical anomaly for 2000 m and remains open to the east and west (Figure 2). No work has been conducted by Orsu to confirm this geochemical anomaly.

The Soviet drillholes C-89 and C-75 traced the sulphide mineralisation for 500 m downdip at a variable angle of 45 to 70 degrees. The best mineralisation intercepted by the Soviet drilling was contained in drill hole C-91, with two mineralised intervals within a package of 27 meters from 39.5 to 66.5 meters: 7 meters grading 0.86% Cu (from 39.5 to 46.5 meters), and 11 meters grading 0.77% Cu (from 54.5 to 65.5 meters), including 4 meters grading 1.1% Cu (from 61.5 to 65.5 meters) (see the Company's press release dated 5 August 2014). Orsu drilled Hole KDDD14-1 approximately 50 m east and along strike from Hole C-91 and intercepted eight mineralised intervals (Table 1), varying in drilled width from 0.6 to 6.5 m (0.3% Cu cutoff) within a wider mineralised envelope of sulphides. From Hole KDDD14-2 in the west to Hole KDDD14-5 in the east there is a documented increase in grade, thickness and number of mineralised intervals. The Company has interpreted that mineralisation was confirmed by Soviet and Company's drilling over a strike length of 700 m from drill holes C-75 and C-89 in the west to drill hole KDDD14-5 in the east. It is further interpreted that all drilling to date was performed on the western flank of the mineralised system, which remains open to the east and downdip. The drillcore logged by Orsu revealed that sulphide mineralisation consists primarily of chalcopyrite and pyrite, with malachite, chrysocolla and sometimes native copper identified within the oxide mineralisation. The mineralisation appears to dip at 60 to 70 degrees to the north. Although in Orsu holes it was intercepted at shallow depth, in Soviet drill hole C-75, 2.8 m of mineralisation grading 0.64% Cu from 287.7 to 290.5 meters, confirmed a downdip continuation of mineralisation for approximately 500 meters.

Table 1 shows average copper and silver grades for all mineralised intercepts at the Kogodai Prospect from the 2014 drilling programme.

# All drillholes were angled at 60 degrees, dipping in the southern direction. Estimated true widths vary from 70% to 90% of drilled width. Gold was assayed at a low level of 0.01 to 0.09 g/t, with four assays exceeding 0.1 g/t Au and one maximum assay of 0.22 g/t Au per 0.9 m in Hole KDDD14-1.

Two hundred and fifty three samples, including 20 standards and 10 duplicates, were prepared from the intervals hosting semimassive and disseminated sulphide mineralisation. All samples were submitted to the ALS Kazakhstan laboratory in Auezov, Zharma district, East-Kazakhstan, and assayed in the ALS laboratory in Chita, Russian Federation. The laboratories are part of ALS Minerals Division, a certified international laboratory, which specialises in assays for base and precious metals and is independent of Orsu. Copper was assayed using the standard ME-ICP technique with a detection limit of 1 ppm. Gold and silver were analysed using the standard atomic absorption technique with detection limit of 0.01 ppm Au and 0.5 ppm Ag.

All sampling procedures and drill core logging were reviewed by Alexander Yakubchuk, a qualified person from Orsu (under guidelines set out in NI43-101) ensuring samples are taken and results from the laboratory are checked in line with NI43-101 guidelines. A stringent QA/QC programme has been put in place to satisfy NI43-101 and JORC requirements. Core samples have been collected continuously from the visually identifiable intervals mineralised with massive and/or disseminated sulphides, including at least 5 meters of host rock above and below such intervals. Blank samples have been inserted every 9th to 19th sample depending of the sampled width, but before standards. Standards have been inserted, on average, every 10th and 11th or 19th and 20th sample within the sample number sequence for the drill core. Assay duplicate samples were selected from quarter core on a random basis from both mineralised and unmineralised intervals, and usually inserted after the standards. The results of duplicate assays were confirmatory.

No NI 43-101 compliant report or mineral resource estimates were published for the Kogodai Prospect. No historical resource estimates of any kind have been published in relation to Kogodai or its satellite occurrences. Potential grade is conceptual in nature. There has been insufficient exploration on Kogodai to define a mineral resource and it is uncertain whether further exploration will result in the target being delineated as a mineral resource. No studies of potential problems, such as extremely erratic results or significant metallurgical difficulties, have been conducted by the Company. The exploration activity on the Kogodai Prospect is preliminary in nature and no conclusive evidence of the likelihood of the occurrence of a mineral deposit was obtained.

The Soviet drill hole results, disclosed above, are from a report by A.A. Shatobin, dated 1971 and titled "Geological report on exploration works of the South Altay exploration party, Ministry of Geology of the Kazakh Soviet Socialist Republic".

Dr Alexander Yakubchuk, Chief Operating Officer and Director of Exploration of Orsu, commented:

"We are pleased to receive such encouraging results from our 2014 scout drilling programme. The results principally confirm presence of high grade copper mineralization at the Kogodai Prospect only a few months after the license was transferred to Orsu. The Company will review its plans in relation to the Kogodai Prospect during Q1 2015."
