Horizonte Minerals awards Pre-Feasibility Study Contract to Snowden Mining Industry Consultants for Araguaia Nickel Project, Brazil

____________________________________________________________________

29 July 2013 - Horizonte Minerals Plc, (AIM: HZM, TSX: HZM) ('Horizonte' or 'the Company'), the exploration and development company focused in Brazil, is pleased to announce that it has awarded the Pre-Feasibility Study ('PFS') contract to advance its 100%-owned Araguaia nickel project ('Araguaia' or 'the Project') located south of the Carajas mining district in northern Brazil, to Snowden Mining Industry Consultants ('Snowden'), a leading global mining consultancy. Snowden as lead contractor will be managing a group of selected third party consulting groups to deliver the PFS, which is expected to be completed in H1 2014. The PFS will further refine the technical and economic parameters of the Project to determine its viability.

The award of the principal PFS contract follows extensive work completed by Horizonte at Araguaia, which included 25,900m of drilling which defined a NI 43-101 compliant resource in February 2012 of 39.3Mt grading 1.39% Ni (Indicated) and 60.9Mt at 1.22% Ni (Inferred) at a 0.95% nickel cut-off; a completed Preliminary Economic Assessment ('PEA'), which returned robust results; and completed metallurgical testwork, which further confirmed the suitability of the RKEF process for the treatment of the Araguaia Nickel ore to produce a saleable ferronickel product.

The results from the recent infill drilling will directly feed into the PFS. As part of the PFS, Snowden will undertake an update to the February 2012 NI 43-101 compliant resource, following the completion of an additional 9,300m of infill drilling by Horizonte in June 2013.

Horizonte CEO Jeremy Martin said, "We are delighted to have finalised the PFS contracts and are pleased to be working with Snowden and the associated consulting groups. We will be using IGEOLOGIA, a Brazilian engineering company, for the Rotary Kiln Electric Furnace plant design; their team has extensive pyrometallurgical processing experience of nickel laterites in Brazil, and globally. The aim is to deliver the PFS in H1 2014 which we believe will be a major milestone and a value driver for the Company. The completion of the PFS will be another step to de-risking our 100% owned flagship project and highlighting Araguaia's financial and technical merits as the next potential major nickel development project in Brazil."

Further Information

The PFS, following internal optimisation work completed by Horizonte and its contractors, will be based upon open pit mining methods. The Company has also completed a geotechnical drilling programme and field work and laboratory testing is in progress. Once all the geotechnical data has been gathered, Snowden will develop a geotechnical model that will enable a pit wall recommendation to be made.

Horizonte is also currently collecting water samples on site, which will be used as a basis for the development of the hydrogeological and hydrological conceptual models. These models, as well as further hydrologic studies, will be undertaken by Snowden representatives to develop mine water control for the open pits and plant. The impact of the mine on the hydrology and hydrogeology in terms of quantity and quality will also be assessed by Snowden.

In addition to finalising a contract with Snowden, Horizonte Minerals has selected three additional sub-contractors which will work with Snowden on the completion of the PFS. IGEOLOGIA is a Brazilian engineering company with in depth experience of pyrometallurgical processing and nickel laterites having worked on a number of large scale Brazilian nickel projects, including the Barro Alto nickel project's Feasibility Study for Anglo American. In addition, Horizonte has selected Brazilian based environmental and social consulting groups Walm and Integratio to complete a full Social and Environmental Impact Assessment ('SEIA') for inclusion in the PFS. The SEIA is a key requirement in obtaining a Mining Licence and Horizonte is on track to have the SEIA report filed with SEMA, the Brazilian Environmental Agency, in Q3 2013.

About Horizonte Minerals:

Horizonte Minerals plc is an AIM and TSX-listed exploration and development company focused in Brazil, which wholly owns the advanced Araguaia nickel project located to the south of the Carajas mineral district of northern Brazil. The project currently has a NI 43-101 compliant Resource of 39.3Mt grading 1.39% Ni (Indicated) and 60.9Mt at 1.22% Ni (Inferred) at a 0.95% nickel cut-off.

The Company has completed a Preliminary Economic Assessment at Araguaia that illustrates robust economics based on low strip ratio with good infrastructure. It is Horizonte's intention to complete a Pre-Feasibility at Araguaia to further prove the economics of the project.

The company is well funded to accelerate the development of its core project.
