Brazilian Gold gives long-suffering investors something to smile about

Brazilian Gold Corporation (TSXV: BGC) jumped 13.5% on Wednesday on three times usual trading volumes, after announcing positive results for initial metallurgical test work on drill-core samples of primary mineralization at its São Jorge deposit in northern Brazil.

In mid-afternoon trade the Vancouver-based explorer, formerly Red Dragon Resources Corp, was changing hands for $0.42 on the Toronto venture board, up 5c and at its highest for the day. The mining sector was generally weak on the day with the TSX S&P Global Mining index down 1.7%

The super-volatile micro-cap with a free float of 79 million shares is worth $38 million in Toronto. Investors who picked up the stock this time last year are still 73% poorer today.



Press Release:

Brazilian Gold Reports Excellent Gold Recoveries of 88 to 92% from Preliminary Metallurgical Testwork for the São Jorge Deposit, Brazil

VANCOUVER, British Columbia–(BUSINESS WIRE)–Brazilian Gold Corporation (TSXV: BGC) is pleased to report results for initial metallurgical testwork on representative composite drill-core samples of primary mineralization from the São Jorge deposit. The study was conducted by Testwork Desenvolvimentos de Processo Ltda., Nova Lima, Minas Gerais, Brazil. All samples were analyzed by SGS Lakefield Geosol Laboratórios Ltda., Vaspasiano, Minas Gerais, Brazil.

Highlights include:

  • 88 – 92% recoveries for direct carbon-in-pulp and carbon-in-leach cyanidation tests at P80 = 200 mesh (75 microns).
  • Gravity recoverable gold of 40-50% at a concentrate grade of 25 g/t.
  • Cyanide consumption of 0.32 kg/t.
  • The mean calculated head grade for the range of tests carried out was 0.78 g/t, well below the diluted resource grade of 0.91 g/t. Brazilian Gold’s metallurgical consultants anticipate an increase in recoveries at higher feed grades.

Samples were taken from nine drill holes, covering a strike length of 600 m over a vertical depth of 60 to 350 m below surface. The samples were crushed to P80 = 1.68 mm and composited into a single representative sample from which a number of 1 kg sub-samples were taken for leach and gravity recovery testwork.

São Jorge gold bearing samples have been shown to be amenable to cyanide leaching at a grind of P80 75 micron grind size. In bottle roll leach tests using this grind size, gold recovery was found to be between 88% and 92%.

Cyanide dosage optimization test work results indicated that cyanide consumption of 320 grams of cyanide per tonne of feed was required in order to achieve the highest gold recovery.

Samples were also subjected to gravity concentration prior to cyanide leaching for which the average recovery was 41% at a feed size of 75 micron P80. The gravity concentrate assayed 25 g/t. Cyanide leaching of the gravity tails product reported gold recoveries between 88 and 92%.

The free milling properties of the gold in the samples indicate that gravity concentration is viable, which should help gold extraction ahead of cyanide leaching resulting in lower cyanide consumption and shorter leach residence time.

Further testwork is planned to better define grind size versus gold recovery and to optimize leach residence time and cyanide consumption rates. Additional work will also include intense cyanide leach recovery potential of the gravity concentrate for its impact on overall gold recovery.

Ian Stalker, CEO of Brazilian Gold, commented “These results add further significant value to our ongoing work on our São Jorge project in the Tapajós region of Brazil. The metallurgical testwork has determined that gold recovery in the 90% range is possible, confirming estimations made in the PEA delivered in July 2011, and we can expect better recoveries at our predicted higher feed grades when operations commence. The ability to separate and recover gold by gravity indicates lower capital and operating costs can be expected.

As indicated by our consultants, the mean calculated head grade for the range of tests carried out was 0.78 g/t gold, well below the diluted resource grade of 0.91 g/t. Brazilian Gold’s metallurgical consultants anticipate an increase in recoveries at higher feed grades.

Based on the results, consideration will also be given to a ‘heap leach’ approach to treating our ore body.

It is also important to note our ongoing optimization of the São Jorge project by Coffey Mining (Canada) following completion of the 2011 drill campaign. The mining inventory recovered from the resource reported in the July 2011 PEA was only 49% and any further increase in the reserve will add extra dollar value to our project.”

About Brazilian Gold Corporation

Brazilian Gold is a Canadian-based public company with a focus on the acquisition, exploration and development of mineral properties in northern Brazil. The Company has title to one of the largest land packages (3,750 km2) in the Tapajós and adjacent Alta Floresta gold provinces. The land package contains green fields to more advance stage projects including the Company’s flagship São Jorge project. Rapid improvements to regional infrastructure continue to provide underlying support to Brazilian Gold’s activities in northern Brazil.

The São Jorge project contains an indicated mineral resource of 11.365 Mt grading 1.0 g/t gold (379,000 ounces of gold) and an inferred mineral resource of 20.673 Mt grading 0.8 g/t gold (558,000 ounces of gold) at a 0.3 g/t gold cut-off (Coffey Mining, June 21, 2011).
