Canadian-based public company, Brazilian Gold has announced the assay results for the last 11 holes of the 2010 drilling program conducted on the Surubim project (Jau target), which is located in northern Brazil’s Tapajós region.
Gold mineralization, which was discovered by the company at the Jau target in the Q1 of 2011, was intersected in 20 drill holes above a depth of 250 m and a strike length of 700 m beneath the surface. The gold mineralization remains exposed at depth and towards the west. The target is accessed by the Transgarimpeiro Highway and is situated roughly 65 km southwest of the company’s São Jorge project.
The JAD-018-11 intersected 3.39 over 4 m, JAD-012-11 intersected 1.35 g/t gold over 12 m, JAD-019-11 intersected 1.16 g/t gold over 12 m. and JAD-013-11 intersected 0.85 g/t gold over 82 m, including a high grade interval of 13.8 g/t gold over 4 m. Jau target is one of the potential gold targets discovered on the Surubim project. Mapping and soil geochemistry are being continued on the Mariazinha target.
The 2011 drill program was devised to assess an east-west trending magnetic anomaly and chargeability. This anomaly was concurrent with auriferous quartz-sulphide veins, which remain exposed in the garimpeiro pit. The company drilled 20 holes on 10 sections with 100 m spacing. The holes were drilled towards the south or north at -55° to -60°.
The holes intersected a steeply dipping, east-west striking mineralized zone in granitoid and felsic volcanic (ignimbrites) rocks. This zone is about 70 m thick and consists of quartz+calcite+sulphide veinlets covered with sericite-silica-pyrite. Sulphides include chalcopyrite, galena, sphalerit and pyrite. Drilling has outlined the zone above a strike length of 700 m and about 250 m beneath the surface. The zone remains exposed at depth and towards the west.
