VANCOUVER, British Columbia--(BUSINESS WIRE)--Brazilian Gold Corporation (TSXV: BGC, "Brazilian Gold" or the "Company") is pleased to report assay results for the final 11 holes of the 2011 drill program on the Surubim project (Jau target) in the Tapajós region of northern Brazil. Gold mineralization at the Jau target was discovered by Brazilian Gold in the first quarter of 2011 and has been intersected in drill holes (20 holes in 6,203 m) over a strike length of 700 m and up to a depth of 250 m below surface; the mineralization is open at depth and to the west. The target is located approximately 65 km southwest of the Company’s advance stage São Jorge project and is accessed by the Transgarimpeiro Highway.
Highlights
- JAD-012-11 intersected 1.35 g/t gold over 12 m,
- JAD-013-11 intersected 0.85 g/t gold over 82 m that includes a higher grade interval of 13.8 g/t gold over 4 m,
- JAD-018-11 intersected 3.39 over 4 m, and
- JAD-019-11 intersected 1.16 g/t gold over 12 m (See table below for a complete set of drill intersections).
- Jau target represents one of several highly prospective gold targets identified on the Surubim project.
- Soil geochemistry and mapping currently underway on the Mariazinha target.

*True thickness is approximately 70-80% of drill interval. |

Note: The large composite intervals are a result of several narrow high grade veinlets within an interval that is anomalous in gold.
Ian Stalker, CEO of Brazilian Gold, commented “The Company is delighted to have discovered gold mineralization in its first holes at the Jau target. The drill program has outlined substantial near surface gold mineralization that has the potential for low cost open pit extraction. The Company is currently evaluating the continuity of the mineralization to determine if the drill spacing is sufficient for an independent NI43-101 inferred resource estimate to be completed at this time, which would further add to the updated NI43-101 resource estimate for our São Jorge project due to be completed this quarter. In addition to drilling at Jau, we have been busy with geochemical and mapping programs at the Mariazinha target, which is located 15 km northeast of Jau, as well as reviewing the results of the airborne geophysical survey completed in Q3 2011 that we expect to generate a number of high priority targets for follow-up exploration.”
The 2011 drill program was designed to test an east-west trending chargeability and magnetic anomaly that was coincident with auriferous quartz-sulphide veins exposed in an historic garimpeiro pit. Twenty drill holes (6,203 m) were completed on ten sections (7900E to 8800E) space 100 m apart; the holes were drilled towards the north or south at -55 to -60°.
The drill holes intersected an east-west striking, steeply dipping mineralized zone hosted in felsic volcanic (ignimbrites) and granitoid rocks. The mineralized zone is up to 70 m thick and is comprised of quartz+calcite+sulphide veinlets with envelopes of sericite-silica-pyrite; sulphides include pyrite, sphalerite, galena and chalcopyrite. Drilling has delineated the zone over a strike length of 700 m and up to 250 m below surface; it is open at depth and to the west.
Laboratory Procedures
Drill core is sampled at 3 metre or smaller intervals using a diamond saw. One half of the sample is archived and the other half is dispatched to Acme Analytical Laboratories Ltd.’s sample preparation facility in Itaituba, Brazil, where the sample is crushed, split and pulverized to -200 mesh. The pulp is shipped to Santiago, Chile or Vancouver, Canada for gold fire assay. Acme Analytical Laboratories Ltd. is an internationally certified ISO 9001 laboratory.
