Brazilian Gold Reports Drill Assays From The Doze de Outubro Property In The
Tapajos Mineral Province of Northern Brazil
VANCOUVER, Feb. 25 /CNW/ - Brazilian Gold Corporation ("Brazilian Gold" or "Company") is pleased to announce initial drill assays from their Doze de Outubro property in the Tapajos Mineral Province (TMP) of northern Brazil. The Doze de Outubro property is the most northerly of four properties that comprise the Maues Project that the Company recently signed an option to purchase agreement with an private Brazilian company in the fourth quarter of 2009 (See News Release 8/09, Dec. 10, 2009).
Drill assays for the first three holes of a 6 drill hole (984m) program on the Doze de Outubro property have been received and significant intersections are tabulated below (Table 1). The drill program was designed to test a 1,000 metre long by 100-200 metre wide northeast trending gold in soil and rock anomaly, which is coincident with a number of garimpeiros workings. The drill holes were collared to the north of the anomaly and drilled to the southeast at an inclination of -50degrees and are spaced approximately 100-200 metres apart; the drill holes tested approximately 500 metres of strike along the southern part of the northeast trending anomaly. The drill holes intersected predominantly maroon, felsic welded tuffs and flows containing a number of quartz and sulphide veined and breccia zones, which correspond to mineralization sampled in the overlying surface trenches and pits. The quartz veined and breccia zones strike northeast and dip steeply; the zones are up to 10 metres in thickness and were intersected up to 30 metres vertically below surface. Higher concentrations of sulphides and silica correlate with higher gold concentrations. Sulphide minerals include pyrite ((less than)5%) and chalcopyrite (trace) and geochemically the samples are anomalous in silver, arsenic, copper, molybdenum and lead. While the drill holes intersected significant gold grades below the garimpeiros workings, given the narrow intercepts and the lack of wide spread pervasive alteration, no further drilling is planned in the immediate vicinity of these workings.

The Doze de Outubro property is underlain by the Paleo-Proterozoic Iriri Group comprised of intermediate to mafic volcanic rocks of the Bom Jardim Formation and overlying felsic volcanic rocks of the Salustiano Formation, which have been intruded by coeval granitic rocks of the Parauari Intrusive Suite. The rocks are largely un-deformed and have the potential to host epithermal and porphyry style gold mineralization. The property (36,070 Ha) has been partially explored to date with approximately 25% of the area covered by stream (209 samples), soil (1,000 samples) and rock (572 samples) geochemistry and geophysics. Sampling crews will continue to extend the surveys to the west to cover two large regional scale structures that extend northeast from the Rosa de Maio property and the contact between a Parauari age stock and volcanic rocks.
The Company is currently de-mobilizing the drill from Doze de Outubro to the Rosa de Maio property located approximately 50 kilometres to the south. Drilling at Rosa de Maio will initially target a large gold in soil and rock anomaly that is approximately 5 kilometres in diameter and is underlain by altered porphyritic granite containing disseminated sulphides and quartz-sulphide stockworks. Grab samples of this mineralization commonly grades several grams per tonne gold, and the style and tenor of mineralization appears to be similar to many of the deposits currently being explored in the TMP. The soil anomaly is coincident with a flexure in a large northeast trending regional scale fault, as are a number of other soil anomalies on the property. Anta creek, which flows eastward into the Parauari River, cuts the northern part of the anomaly. The creek and its tributaries were the focus of extensive alluvial mining in the 1980's and 1990's with un-official gold production estimated to be 0.5 million ounces.
Laboratory Procedures
Mineralized intervals in drill holes are sampled at 2 metre or smaller intervals using a diamond saw. One half of the sample is archived and the other half is dispatched by plane to the Acme Analytical Laboratories Ltd.'s sample preparation facility in Itaituba, Brazil, where the sample is crushed, split and pulverized to -200 mesh. One sample split is shipped to Santiago, Chile for gold fire assay with atomic absorption finish and a second sample split is shipped to Vancouver, Canada for 36 element induced coupled plasma - multispectral analysis. Acme Analytical Laboratories Ltd. is an internationally certified ISO 9001 laboratory. Brazilian Gold's Quality Assurance - Quality Control Program involving insertion of appropriate blanks, standards and duplicates was employed with acceptable results.
Garnet Dawson, M.Sc., P.Geo. (British Columbia), Vice President, Exploration for the Company and a Qualified Person, as defined by National Instrument 43-101, has reviewed and approved the technical disclosure contained in this News Release.
