The Batistão project is located in the Peixoto de Azevedo Gold Province in Mato Grosso state.
The project is host to an auriferous quartz+sulphide stockwork system that has been partially tested by short reverse circulation drill holes that commonly ended in mineralization.
Brazilian Gold plans to complete geochemical and geophysical surveys in 2011 followed by diamond drilling.
Ownership
- Brazilian Gold owns 100% of the project subject to a 2% NSR that can be purchased for US$666,667.
Land
- One exploration concession for a total area of 10,000 Ha.
History
- 1992-1995, Western Mining outlined a large gold in soil anomaly (>1 km by 300 m) that was tested by short reverse circulation drill hole (1,287m in 24 holes) program that intersected auriferous quartz-sulphide stockwork.
- 2006, Talon Metals (formerly Brazmin) applied for concession over the Batistão prospect.
Description
- Western Mining completed a regional exploration program in the Peixoto de Azevedo Gold Province from in the early 1990's that identified a significant stream sediment anomaly in the Batistão area.
- A soil grid was established over the stream geochemical anomaly, which defined two gold anomalies, called Bat-East and Bat-West.
- Ground geophysics, auger drilling and a subsequent reverse circulation (RC) drilling program were completed to evaluate the targets.
- The Bat-East gold-in-soil anomaly is characterized by a series of gold values ranging from 50 to greater than 200 Au ppb. The 100 ppb line-contour delineates an elongated west to northwest trend that is 750 metres long by 70-170 metres wide. The Bat-East anomaly is open to the east.
- The Bat-West gold-in-soil anomaly is delineated by a series of values ranging from 50 to greater that 200 ppb. The 100 ppb line-contour outlines a 300 metres long by 70-200 metres wide zone that trend is W-NW and along the same regional structure that passes through the Bat-East anomaly. The Bat-West anomaly is open to the west and is closed to the east.
- Auger drilling tested the soil anomalies (109 auger holes in 762 metres) with positive results.
- Reverse circulation drill holes (24 drill holes in 1,287 m) were drilled to the north or south with a dip of -55° and tested a zone from 40 to 60 metres below surface; selected assays from that program are shown in the table below.

- The drill holes intersected auriferous quartz+sulphide stockworks hosted in granitic rocks associated with silica, sericite and epidote alteration.
2011 Exploration Program
- Compile historic work and complete soil geochemical and geophysical surveys to identify targets for diamond drilling.
- Phase One (1,000) diamond drill program planned to start in Q4 2011.
