Majestic has secured a 10,000 hectare mineral claim prospective for diamonds near the town of Monte Alegre, state of Para, on the northern side of the Amazon River. To date, geological work completed by the Company and other explorers has been promising with the identification of dozens of geological and geophysical anomalies, including diamond indicator minerals and lamproite pipes (host rock of diamonds).

Geology and Mineralization

This area is situated in a favorable geological setting within the Amazon Craton with fairly good access and general infrastructure. Aeromagnetic and radiometric airborne surveys previously completed by Rio Tinto in the late 1990s have identified more than 100 geological anomalies. Follow-up work has successfully identified four lamproite pipes in the region with preserved crater facies. Several DSF (diamond stability field) chromites have been identified. In a small sample (18 kg) collected from one of the pipes, one microdiamond was identified. The Company's current claim area contains one known lamproite and dozens of geological anomalies that share similar characteristics to the other known lamproites in the region.

The Company has plans to conduct more comprehensive field work to confirm the existence of additional pipes in its claim area and the surrounding region. The geology is favorable for hosting multiple diamondiferous pipes. Additional trenching, mapping, magnetic surveying, stream sediment sampling, and drilling in and around the anomalies is expected to provide new discoveries.

Majestic owns a 10,000 hectare diamond claim area near the town of Novo Progresso, located in the southwestern portion of the state of Para. The Novo Progresso region is known to host both gold and diamonds and, in the opinion of Majestic's management, it boasts of superb geology for hosting commercial diamond deposits. Previous work conducted by Rio Tinto and Majestic's co-founder, Pedro Jacobi, has identified significant diamond indicator minerals and microdiamonds in samples taken from a number of different streams located throughout the region.

Geology and Mineralization

This diamond target area is ranked as a high priority for the Company due to its geotectonic settings, lack of sedimentary cover, the chemistry of indicator minerals and the presence of high quality diamonds in gravels. A number of new, high-quality alluvial diamond deposits in the region have recently been discovered with some diamonds reaching as large as 50 carats. The geological and geochemical reconnaissance conducted to date has focused on specific targets such as diamond occurrences, favourable structures on radar and LandSat images, geochemical anomalies and mag-gamma anomalies.

A large number of pan concentrates and loam samples have been collected and analyzed over the selected target areas of this region. This sampling program has successfully outlined a number of important anomalies. These anomalies are situated in old Proterozoic terrain not covered by young sediments that may have redistributed the indicators minerals. In all anomalous sites microdiamonds, pyrope garnets (including G10s) and chromites that fall within the diamond stability fields (DSF) have been confirmed in the active stream sediments. The Company presumes that the source kimberlite and/or lamproite pipes are within a short distance. The next phase of work on the project includes additional stream sediment sampling, geological mapping, and geomagnetic surveying.

Majestic owns two diamond mineral claims in the state of Piaui, totaling 2,900 hectares. In the 1970s and 1990s DeBeers and Rio Tinto, respectively, conducted diamond exploration reconnaissance in the region where the Majestic's diamond claim areas are located. The region is known to host high grade alluvial diamond deposits and low-grade diamondiferous kimberlites. The Company has identified potentially four kimberlite pipes in its claim area located in close proximity to known alluvial diamond deposits.

The claim areas are located within the Parnaiba Basin, located in the western portion of the Northeast Region of Brazil. The Parnaiba Basin is well known by its diamond occurrences. There are a number of important diamondiferous alluvial deposits that have, during decades, produced large amounts of good to high quality diamonds. The kimberlite targets in the diamond claim areas owned by the Company in this area are believed to have never been tested.
