Brazauro Resources announced the appointment of Mr. Elton Pereira as senior manager of Brazauro's development and exploration programs currently underway in the Tapajós region of northern Brazil.
These programs include resource definition drilling at the Tocantinzinho property (TZ) as well as advanced exploration activities at the Mamoal and Batalha properties.
Mr. Pereira worked as a project manager for Rio Tinto Exploration in Brazil, from 1993 until 2004. During his tenure at Rio Tinto, he was intimately involved in the discovery of the Jurupari bauxite deposit in Pará state, and also played a role in the discovery of the Ouro Roxo, São Jorge, Palito and V3 primary gold prospects, all of which occur in the Tapajós gold field.
Before Rio Tinto, Mr. Pereira worked as a mine and exploration geologist for KDG da Amazônia, at the former Cerrito do Ouro gold mine in Rio Grande do Sul state. His responsibilities for KDG included documentation of the mine geology and near-mine exploration.
Elton's extensive experience and knowledge of the Tapajós, along with his ability as a proven mine finder, greatly enhance Brazauro's opportunity for success. Brazauro is very happy to have Mr. Pereira in this key position, and extends him a warm welcome.
Mamoal Property
All results for samples collected at Mamoal during 2004 have been received and compiled. Over 2400 soil auger samples and approximately 150 channel and chip samples were collected over a 10 km x 6 km area within the Mamoal concession.
The soil samples were collected from a depth of 1.2 meters, on 25 to 100 meter centers along 17 different lines and 7 different drainages. Sample values ranged from below detection limit to 2.5 g/t Au in soils, and greater than 1.5 oz/ton Au in channel samples.
Several narrow vein samples returned over 10 oz/ton, with at least one collected from a wooded, virgin area, not worked by the garimpeiros (artisanal miners).
Approximately 25% of the samples reported values below laboratory detection limits (5 ppb), generally collected from areas at the extremity of the survey area.
The results reveal the following three geochemical gold anomalies:
A) A 1.0 km x 0.6 km soil and rock chip anomaly occurs over the traditional Mamoal garimpo (artisanal mining) area in the center of the concession area, with auger soil sample results ranging from 20-290ppb gold, channel sample results between 0.1 and 4.9 g/t gold and rock-chip samples ranging from 10 to 221 g/t gold.
B) A 1.2 km x 1.0 km, soil anomaly is located one kilometer southeast of this zone with auger soil sample results ranging from 50- 430ppb gold and channel samples results between 0.4 and 44g/t gold.
C) and a large 1.6 km x 1.4 km soil anomaly containing auger soil sample results from 50-1500ppb, occurs over two kilometers to the west of the traditional mining area. This latter anomaly occurs in an area that has seen very little historic garimpeiro activity, but does contain a few small prospect pits and shafts.
The strongest zones are up to 400m wide in this latter anomaly, and appear to trend west-northwest, parallel or sub parallel to the underlying Tocantinzinho structural corridor.
Mark Jones, chairman, said, "We consider these results to be very exciting. When compared with the Company's soil sampling program at TZ, they are particularly exciting.
The number of anomalies, the continuity of gold mineralization and especially the size of the anomalies are substantially greater than at TZ, and we were very encouraged, and confident, when we started drilling at TZ based largely on the surface geochemistry there.
We are putting a priority on the ongoing pre-drilling exploration program at Mamoal and expect to be drilling there as soon as possible."
Exploration activities planned for Mamoal this year include construction of a small camp followed by closer-spaced soil sampling over the three anomalous zones described above.
Data generated by this program will be evaluated in mid-summer 2005, with follow-up drilling planned for the July-September period.
The Mamoal project lies along a major WNW-ESE mineralized trend in the Tapajós that hosts several significant productive garimpos including Brazauro's Tocantinzinho, in addition to São Jorge, Cuiú Cuiú, and Bom Jardim, all of which host extensive primary gold mineralization.
The exploration program is being carried out under the direction of Dennis Moore, director of Jaguar Resources do Brazil, and exploration manager (a member of the Society of Economic Geologists and the Qualified Person for the project) and follows procedures and practices previously disclosed by the Company. Mr. Moore spent several years exploring the Tapajós on behalf of Altoro Resources in the late 1990's.

The small, coastal town of Condé is located just a twenty minute's drive from João Pessoa, the capital of Paraíba. The Northeast of Brazil has historically been a place of encounter and mixing between peoples. For millenia groups of indigenous people fished, farmed, migrated and sometimes fought along this large, fertile area. 
The Brazilian diplo-MÁ-cia (bad diplomacy) carries on its accelerated course towards the non-acknowledgment of human rights, although sometimes it takes pleasure in saying that it does precisely the opposite. The visit of Iran's president, Mahmoud Ahmadinejad, is another example of a diplomatic omission that verges on hypocrisy. 
On July 4, 2006, representatives of Argentina, Brazil, Paraguay and Uruguay met in Caracas to sign the protocol for the entrance of Venezuela into the Southern Common Market (Mercosur). After two and a half years, the protocol was approved by the legislative bodies of Argentina and Uruguay, and as of now it may be only days away from being ratified by the continent's economic megalith, Brazil. 
Some sectors of the fight against AIDS have suggested that Thabo Mbeki, the former president of South Africa, committed genocide through his absence from the fight against the illness in his country throughout his two terms. 
One hundred and eleven years after Brazil abolished slavery, the number of workers deprived of their freedom is still huge. They raise cattle, produce charcoal, sugar cane or timber. Some of them, most undocumented Bolivians, work in basements of small apparel factories in São Paulo and other metropolis. 
On November 7, 2009 a few friends and I had an opportunity to take a look inside a Brazilian jail outside the city of Rio de Janeiro. We were able to take some amateur footage of our experience on video (see link below). It's no surprise, of course, that the typical Brazilian jail lacks some of the functionality of those in North America or Europe, but our experience that day was quite shocking. 
Depletion of the Amazon Rainforest is not a new concern facing environmentalists, biologists, ecologists, and a growing number of the Amazonian indigenous peoples. For decades they have feared for the fate of the world's most biologically diverse and species-rich hothouse. 
Geisy Arruda made history this week in Brazil, but for all the wrong reasons. What began as a poorly planned fashion statement has become a worldwide tale. Geisy decided to wear a pink mini-dress to her private college in São Paulo state, and after that, all hell broke loose. 
The push of vigilante groups in Rio de Janeiro's favelas (shantytowns) in the last three years is the most important and alarming information of the just-released study by the Rio de Janeiro University's Violence Research Center (Nupev-Uerj). 
A dispute over drug trafficking territory in Rio de Janeiro has intensified lately, leaving in its wake unprecedented acts of violence, such as the downing of a police helicopter in the northern zone of the city on October 17. Three policemen died and another two were injured. This event has drawn the attention of the international media, who are raising the issue of public security for the 2016 Olympics to be held in Rio.
