alluvial diamonds and a lot of deposits are mined by confined workers often clustered into small
organizations. More than a few foreign investors are vigorously exploring and evaluating kimberlitic
and alluvial property; in demanding the Mina Gerais and Sao Paulo States. A lot of of these companies
have found hundreds of kimberlites in many areas but nopne has proved to be an enough to justify a mine.

sporadically worked by garimpeiros, who have healthier several high quality large stones, judged to
be the best excellence in Brazil. But, following poor results from an extensive bulk sampling program (2 400 cubic meter), the partners have decided that the belongings had little economic latent. On
an adjoining property, Verena also have a joint scheme with Rio Tinto over the Marimbondo project where
they are probing for a hard rock source for the diamondiferous gravels located in the area. Canadian
juniors Canabrava Diamond Corporation and Southern Era have a joint venture larger than the Canabrava
project located in Minera Gerais State. Southern Era have had the option to 50% of the joint venture
after committing CDN$20 million on activities focused on evaluate both primary and alluvial targets.
