Ltd (Coffey Mining) under its Brazilian office in Belo Horizonte has been commissioned by Brazil Resources Inc (Brazil Resources) to prepare an independent Technical Report about the early exploration stage Montes Áureos Gold Project, in Maranhão State, Brazil. The Company’s mineral property is considered to represent an Exploration Project which is inherently speculative in nature. However, Coffey Mining considers that the property has been acquired on the basis of sound technical merit. The property is also generally considered to be sufficiently prospective, subject to varying degrees of exploration risk, to warrant further exploration and assessment of its economic potential, consistent with the proposed programs. Location The Montes Áureos Gold Project is located in the municipality of Centro de Guilherme city, region of Gurupi, approximately 200km directly west of São Luís city, the capital of the Maranhão state (Figure
