Brazil Resources Inc. Identifies Large Copper-Gold Mineralized Zone at Artulândia Project in Goias State, Central Brazil
VANCOUVER, Sept. 6, 2012 /PRNewswire/ - Brazil Resources Inc. (the "Company" or "Brazil Resources") (TSX-V: BRI) (OTCQX: BRIZF) is pleased to announce that recent rock sampling, geophysical and soil geochemical surveys at its Artulândia project have identified an anomalous copper gold zone of approximately 1,000m by 250m, which is open in all directions. The Artulândia project covers 12,000 acres within the Company´s 247,000 acre Pireneus district and is located in Goias state, one of the most prolific mining districts in Brazil.
Stephen Swatton, President and CEO, stated, "Our geological team believes Artulândia has the potential to be a significant discovery, made with a modest budget in an area that has not had previous mining or exploration activity. Based on preliminary exploration data, similarities are being drawn with Yamana's Chapada Copper-Gold Mine to the north. However, we acknowledge that the Artulândia project is in the early stages of exploration and, therefore, more work, including drilling, needs to be done to fully realize and understand this project."
Highlights from the new results obtained at Artulândia include:
- Target ART-1; Further follow-up work completed on target area ART-1 has confirmed new mineralized outcrops, with increased copper values of up to 0.81%, gold values of up to 2.3 g/t and silver values of up to 344 g/t, plus additional anomalies of lead-zinc. A geophysical survey has identified a main IP anomaly trending along strike for approximately 400m, which coincides with the geochemically defined gold-copper zone identified by previous soil and rock chip sampling. ART-1 is considered a priority, and the next phase of exploration is expected to include diamond drilling of this target. Geochemical sampling indicates that the mineralization extends for an additional 600m to the east of the main IP anomaly (Targets ART-2 and ART-3).
- Target ART-5; A new zone located approximately 750m NE of ART-1 has been discovered comprising gossans trending along strike for approximately 700m. These gossans are similar to those found at target area ART-1. A total of 50 rock geochemical samples have been collected from target area ART-5 and sent to the laboratory to confirm the presence of mineralization.
In its news release dated April 26, 2012, Brazil Resources announced the first results of a geochemical sampling program at Artulândia and identified eight target areas (ART-1 to ART-8) with elevated copper, gold, lead and zinc values surrounding a large intrusive granitoid with rock grab sample results of up to 1.2 g/t gold, 0.7% copper and greater than 2% lead-zinc in separate samples.
Since May 2012, follow-up geochemical sampling and detailed geological mapping programs have been completed on target areas ART-1 and ART- 5. In addition a geophysical IP/Mag ground survey has been completed and a trenching program has been initiated at ART-1. To date, assay results are available for a total of 603 rock grab samples, 1,581 soil samples and 62 stream sediment collected from target areas ART-1 and ART-5.
Based on petrographic and detailed geochemical and geophysical data interpretation, Company geologists believe the geology at Artulândia may be a porphyry copper deposit. Therefore comparisons are being drawn with the Chapada Mine operated by Yamana Gold, which is located approximately 140 km north of the Artulândia project. Chapada produced 135,000 oz of gold and 166 million pounds of copper in 2011 as publicly disclosed by Yamana. Readers should be aware that the comparison to Chapada contained herein is based on preliminary exploration by the Company to date and substantial additional exploration is required to define the extension, continuity and geology of the mineralized zones at Artulândia, which does not currently have any defined resources, and, therefore, the results at Chapada are not necessarily indicative of the potential of the Artulândia project.
The geophysical survey was performed by Fugro Geophysics, and processed by Reconsult Geofísica. The IP-resistivity survey comprised 7.65 line kms, and the magnetics survey comprised 23.35 line kms. The grid lines were oriented north-south and each line was 100 meters apart.
The Company plans to further its exploration efforts on all the remaining targets. A diamond drill program to investigate Target 1, and possibly Targets 2 and 3, is currently under consideration. Targets ART-4, ART-5 and ART-6 have been outlined by the recent geophysical survey and will be investigated by additional rock sampling and mapping. The current geochemical/geophysical results only represent the investigation of two targets (ART-1 and ART-5) of the eight geochemical targets initially identified by the Company.

Target 1 is defined by a 400m long high IP trend, the inversion sections show that this trend could be dipping from west to east, going from a superficial response to a deeper signature. This possibility, if proven correct, could add another 600m to this target, effectively extending Target 1 to the eastern boundary of Target 2 (Figure 2).

Note Regarding Scientific and Technical Information
Paulo Pereira, the Company's Vice President of Exploration has supervised the preparation of and reviewed the technical information and verified the data contained in this document. Mr. Pereira holds a Bachelor degree in Geology from Universidade do Amazonas in Brazil, is a qualified person as defined in National Instrument 43-101 and is a member of the Association of Professional Geoscientists of Ontario.
The reconnaissance sampling at the Artulândia project was performed using stream sediment sampling to cover the entire area of the claim block. Streams sediment samples were collected using 10 liters constant volume samples and the collected material was panned in the field for gold color counts. Follow-up sampling was completed on anomalous areas defined by the results of the stream sediment sampling. Soil samples were collected on regular grids (200m x 50m) at 0.30 m depth. The material excavated in each soil sampling location was homogenized and a 2 kg representative sample was collected. Rock samples (hand-specimen size) were collected during geological mapping over the entire area and on target area ART-1 rock samples were collected over regular grid (100m x 25m) and on representative mineralized outcrops.
Brazil Resources operates QA/QC controls of sampling and analytical procedures. For geochemical sampling (stream sediment, soil, rock) duplicates are inserted in the sample batches at a reason of one duplicate for every ten samples. Samples from the Artulândia project are transported by the company staff from the project by road to SGS-Geosol Labs in Goiania, Goias for preparation and pulps are sent to SGS-Geosol Labs in Vespasiano, Minas Gerais, Brazil in secured and sealed sample bags for analysis. Samples are assayed by the lab for gold using a 50 gram fire assay with AAS finish and ICP for 37 elements.
