About Horizonte Minerals:

Horizonte Minerals plc is a leading exploration and development company in Brazil with two committed major mining partners - Teck Resources and AngloGold. The Company's wholly owned flagship nickel project, Araguaia, is located south of the world-class Carajas Mineral district in northern Brazil. The Company has released an updated 43-101 Mineral Resource Estimate of 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, which places the project in the upper quartile of developing global nickel assets in terms of size and grade.

During the past year Horizonte has delivered on key milestones within budget and on schedule. 2012 will be active in terms of milestone delivery adding value to the Company as it continues to develop Araguaia towards production.
