Pit Optimisation Study for the Mikei Gold Project, Migori, SW Kenya

Date: 12th June 2013

Red Rock Resources plc (AIM:RRR), the mining and exploration company with an iron ore project in Greenland, a producing gold mine in Colombia and interests in steel feed, uranium and rare earths is pleased to announce the results of a Pit Optimisation Study ("The Study") on its Migori Gold Project, in which it has a combined direct and indirect investment of approximately 47%. Based on the technical and economic parameters the Company considers that these results demonstrate economic potential and support project advancement to Scoping Study level. The pit optimisation work has been undertaken by SRK Consulting (UK) Limited ("SRK").

Pit Optimisation Results

Highlights

·; Conceptual results from Pit Optimisation Study completed on the Mikei Gold Project ("MGP") supports on-going development to Scoping Study stage;

·; Nyanza ("NZ") prospect followed by the MK prospect show the best potential as starter pits due to lower metal price sensitivity and favourable conversion from Mineral Resources to diluted pit shell metal inventories (NZ ~77%);

·; 6.5 Mt diluted mineral inventory at 2.0 g/t Au for 419 koz Au at a stripping ratio of 4.3 (twaste:tore) contained within a 1,300 US$/oz pit shell, representative of the potential open pit mining inventory;

·; Identification of potential high grade starter pits at the NZ and MK prospects with a combined diluted mineral inventory of 1.8 Mt at 3.9 g/t Au for 221 koz Au and relatively low optimised pit shell Cash Cost of 476 US$/oz Au;

·; 11.4 Mt undiluted mineral inventory at 1.9 g/t Au for 689 koz Au contained within a 1,700 US$/oz pit shell, representative of the Mineral Resources limited by open pit potential; and

·; The results of the pit optimisation will be used to guide further Resource development including drilling, metallurgy and a more detailed scoping level study ahead of feasibility.

SRK Comments on Project Potential

SRK concludes that the work completed to date (resource modelling, metallurgical test work and pit optimisations) is sufficient for a scoping study to be undertaken for the MGP. Additional potential exists to integrate a scoping study with the adjacent Macalder Tailings Resource to develop a larger overall project for Red Rock's Kenyan assets.

SRK Comments on Exploration Potential

The pit optimisation work demonstrates that the pit shell economics are limited for the KKM, KKM-West ("KW") and Gori Maria ("GM") deposits based on the current Mineral Resource, there is however potential for larger optimised pit shells for the MK and NZ deposit if geological grade continuity is realised and lateral and/or depth extensions to the high grade ore shoots.

Detailed interpretation work is on-going by site geologists to determine the structural controls on mineralisation and delineate the high grade ore shoot at the NZ prospect. This will guide future resource delineation drilling for improving confidence in grade continuity and investigating potential lateral or depth extensions to the Mikei Resource.

Further Work

With these results, the company is working on a detailed plan of activities to examine the potential of the MGP to be developed as a small scale open pit project, with particular focus on the NZ deposit. Further work on the MGP will include:

·; Drilling to test both the plunge extent of the high grade shoot at NZ, and the continuity and grade distribution within the defined system.

·; Exploration drilling along the Mikei shear zone to target potential lateral and depth extensions to current 1.2Moz JORC resource;

·; Advanced metallurgical test work to assess whether there is a correlation between the high sulphide content and a decrease in leach recoveries;

·; Possible geotechnical (RQD) drilling, further geodetic survey, and plant design and costing, hydrology and environment will be examined;

The work completed to date on the MGP (resource modelling, metallurgical test work and pit optimisations) is sufficient for a scoping level study to be undertaken. This would provide a conceptual evaluation of the project economics inclusive of production schedules, derived operating costs and capital cost estimates and a discounted cashflow model. The results of a scoping study, in addition to an economic assessment of the MGP would provide a more detailed project evaluation on which a decision to progress the project to advanced feasibility can be made.

Company Chairman Andrew Bell comments:

"This work takes the existing Resources, at the tonnages and grades so far reported, and gives us a snapshot of optimised pits at a certain gold price and certain cost assumptions. This shows where we have opportunity, and where we need to do more work. This is an important step forward on the path to feasibility."
