O Capitão is a 3.2km² tenement north-west of Cleveland’s Premier tenement. A confused ownership status, as well as garimpo tailings, has until now stopped major companies from modernizing the project. Cleveland has overcome these barriers and is positioned to be the first professional mining company to build a mine at the highly sought after location.
The infrastructure available to O Capitão is good. Sealed roads and gravel tracks link the site to the town of Crixás, which is 4km away as the crow flies and 10km from the Premier Mine processing plant.
The site was originally drilled in the 1980’s by Serra Grande Mineração and, after significant gold-bearing intercepts were made, an application for mining was lodged. That company was unable to continue its work due to the presence of garimpeiros (artisanal miners). As many as 6000 garimpeiros worked at O Capitão throughout the ‘80’s until the town they established was abandoned after an outbreak of yellow fever.
The garimpeiros were working on a seam that outcropped and gently dipped down to about 40m. Wall rock highlights of this seam are up to 6m thick with over 20 g/t Au. The garimpeiros also dug around 300 shafts across the property, where the prospective geology can be seen outcropping extensively. Ore has been extracted as deep as 80m from several shafts next to the main pit. Garimpo mining is now illegal in Brazil.
