Horizonte CEO Jeremy Martin said, "I am pleased to file the NI 43-101 report for the new resource at Araguaia, which, at a 0.95% Ni cut-off, totals 39.3 million tonnes grading 1.39% nickel in the Indicated category and 60.9 million tonnes averaging 1.22% Ni in the Inferred category.  Work is now focussed on the metallurgical test work and the Preliminary Economic Assessment in H1 2012, and we look forward to updating shareholders on our progress in due course."

Further Details

The Mineral Resource Estimates are effective January 10, 2012 and are reported using a range of Ni cut-off grades (Table 1) and detailed by geological host at a 0.95% Ni cut-off (Table 2).

Table 2:  Mineral Resources at 0.95% Nickel Cut-off Detailed by Geological Host

There are no material differences in the mineral resource estimates to those presented in the news release of 10 January 2012 and Table 1 remains unchanged, however there are some differences in the average elemental values tabulated for the individual material types for the Inferred category in Table 2. These are marked in italics in the table.

The data was validated and the Mineral Resource Estimates were prepared by Marc-Antoine Audet P. Geo., Ph.D, an independent Qualified Person as defined in NI 43-101.

About Horizonte Minerals:
Horizonte Minerals plc is an AIM and TSX listed exploration and development Company with a portfolio of nickel and gold projects in the Carajas District of Brazil. The Company is focussed on creating value by generating and rapidly advancing exploration projects in tandem with joint ventures with major mining companies, providing mid-term cash flow, which is then used to develop the business and pipeline projects.

Horizonte has two committed major mining partners: Teck Resources Limited, a major strategic shareholder in the Company, and AngloGold Ashanti Limited, a JV partner on the gold portfolio.

Horizonte owns 100 per cent of the advanced Araguaia nickel project located to the south of the Carajas mineral district of northern Brazil.; the project has the potential to deliver a resource with size and grades comparable to other world-class projects in northern Brazil.

In addition, Horizonte and AngloGold Ashanti have a US$5.3 million exploration alliance to generate and develop new and existing gold targets within two areas of Brazil and a further JV with the major whereby AngloGold Ashanti can earn into 51% of the Falcao gold project by expending US$4.5 million over three years with the right to earn a further 19% by taking the project to Pre-feasibility Study.

Horizonte is well funded to accelerate the development of its core projects.
