ORTAC RESOURCES LTD

("ORTAC" OR THE "COMPANY")

Further Investment in Casa Mining Ltd.

Ortac Resources Ltd ("Ortac"), the AIM listed exploration and mine development company, is pleased to provide an update on its investment in Casa Mining Ltd ("CASA"), a private company registered in Mauritius that holds prospective gold mining and exploration licences in the Democratic Republic of Congo ("DRC").

Highlights:

   --     Ortac increases it shareholding in CASA to just under 20% of enlarged share capital in CASA 

Vassilios Carellas, Ortac's CEO, commented: "The recently announced placing has enabled Ortac to take up its option and subscribe for further shares in CASA.

With over 1 million ounces of gold discovered so far, the Misisi Gold Project, with its potential for a low cost, open pit operation, is gaining a profile as a project that can be brought into production quickly.

By increasing Ortac's stake in CASA, we can continue to play our role as a supportive shareholder in the development and marketing of Misisi, which is now bearing all the hallmarks of a project that has the investment profile fitting with the current gold project investment market."

Investment

Through a private placement carried out by CASA, Ortac has increased its interest and holds 1,304,667 shares representing 19.63% of the enlarged share capital of CASA.

About Casa Mining Ltd.

CASA is a private Mauritian registered company that is the 71.25% owner and operator of the Misisi Gold Project located in South Kivu, eastern DRC, approximately 350km south of Bukavu and 180km north of Kalemie.

The CASA licence holdings consist of three contiguous mining licenses (133km(2) ), issued in March 2015 and valid for 30 years. These licenses, which encompass a 60km strike length of the Tanganyika graben within the Rusizian belt ("Misisi Corridor"), include the Akyanga deposit along with the Lubitchako, Tulongwe, Kilombwe and Mutshobwe prospects (targets).

Over the last six years over $30m was spent developing these licenses. In addition to the regional geophysical surveys completed over these license areas in 2011, CASA have carried out 19,522m of diamond drilling, 2,720m of reverse circulation drilling and excavated 6,274 line metres of trenches on their respective licenses.

At CASA's most advanced project, the Akyanga deposit, SRK has reported a Mineral Resource within a $1,200/oz gold selling price and 0.5 g/t Au cut-off grade optimised pit shell. This comprises an Inferred oxide gold Mineral Resource of 5.5 Mt at a grade of 1.5 g/t Au for approximately 272 koz of contained metal. SRK has further reported an Inferred transition gold Mineral Resource of 16.2 Mt at a grade of 1.8 g/t Au for approximately 927 koz of contained metal.

MDM, in conjunction with SRK, completed a scoping feasibility study for the Akyanga deposit resulting in an ungeared NPV (8%) and IRR of $171m and 35% respectively at a $1,300/oz gold price. This assumes a contract mining scenario with an initial capital cost estimate of $87.4m and a total operating cost of $628/oz.

Following the internal workshop and the non-code compliant updated resource estimate of over 2.3 Moz of gold produced by CASA's independent experts, it is currently reviewing its strategy and weighing up its options in developing its Missisi project.

The Company will make further announcements as appropriate.

Glossary

   Au                                                          Au means gold. 

carbon-in-column carbon-in-column or CIC means a technological operation in which gold and silver dissolved in clean leach solution are absorbed onto activated carbon which is layered horizontally in vertical columns.

Core drilling core drilling means a drilling method that uses a rotating barrel and an annular-shaped, diamond impregnated rock-cutting bit to produce cylindrical rock cores and lift such cores to the surface, where they may be collected, examined and assayed.

CIM The CIM Definition Standards on Mineral Resources and Reserves (CIM Definition Standards) establish definitions and guidance on the definitions for mineral resources, mineral reserves, and mining studies used in Canada.

cut-off grade cut-off grade means the minimum grade at which mineralized material can be economically mined and processed (used in the calculation of ore reserves).

diamond core drilling diamond core drilling means a method of exploration in which rock samples from underground are retrieved as core (whole rock cylinders) for further examination and assaying.

Dip The inclination of a geologic structure (bed, vein, fault, etc.) from the horizontal; dip is always measured downwards at right angles to the strike.

Exploration exploration means activity ultimately aimed at discovery of ore reserves for exploitation. Consists of sample collection and analysis, including reconnaissance, geophysical and geochemical surveys, trenching, drilling, etc.

   Ga                                                          means a billion years. 

Graben means an elongated block of the earth's crust lying between two faults and displaced downwards relative to the blocks on either side, as in a rift valley.

   g/t                                                         g/t means gram per tonne. 

heap leach heap leach means a technological operation in which crushed material is laid on a sloping, impervious pad where it is leached by cyanide solution to dissolve gold and/or silver. Metals are subsequently recovered from pregnant leach solution by CIC or the Merrill Crowe process.

Inferred resource inferred resource means that part of a resource for which tonnage, grade and content can be estimated with a low level of confidence. It is inferred from geological evidence and assumed but not verified geological and/or grade continuity. It is based on information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes which may be limited or of uncertain quality and reliability.

Indicated resource indicated resource means that part of a Mineral Resource for which tonnage, densities, shape, physical characteristics, grade and mineral content can be estimated with a reasonable level of confidence. It is based on exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill-holes. The locations are too widely or inappropriately spaced to confirm geological and/or grade continuity but are spaced closely enough for continuity to be assumed.

JORC The Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves ('the JORC Code'). The JORC Code provides a mandatory system for the classification of minerals Exploration Results, Mineral Resources and Ore Reserves according to the levels of confidence in geological knowledge and technical and economic considerations in Public Reports.

Mineral Resource Mineral Resource means a concentration or occurrence of material of intrinsic economic interest in or on the Earth's crust in such form, quality and quantity that there are reasonable prospects for eventual economic extraction. The location, quantity, grade, geological characteristics and continuity of a Mineral Resource are known, estimated or interpreted from specific geological evidence and knowledge. Mineral Resources are sub-divided, in order of increasing geological confidence, into Inferred, Indicated and Measured categories.

Reverse circulation means a drilling method that uses a rotating cutting bit within a double-walled drill pipe and produces rock chips rather than core. Air is circulated down to the bit between the inner and outer wall of the drill pipe. The chips are forced to the surface through the centre of the drill pipe and are collected, examined and assayed.

SRK SRK Consulting (UK) Limited (SRK) is an associate company of the international group holding company, SRK Consulting (Global) Limited (the SRK Group).

Strike means a horizontal extension of an ore body or mineralisation.
