HOUSTON, March 3 /PRNewswire-FirstCall/ -- Brazauro Resources Corp. (TSX.V: BZO), a pure-play Brazilian gold exploration company, today announced that the Preliminary Economic Assessment ("PEA") for the Company's 100%-owned Tocantinzinho property, conducted by NCL do Brazil Ltda., has been filed and is available at http://www.sedar.com/ and at Brazauro's website, http://www.brazauroresources.com/. The PEA is based on drilling completed through September 2009 as well as a significant body of engineering and cost estimation. It concludes that the 44,525-hectare Tocantinzinho property in the underexplored Tapajos region of Brazil offers compelling economics and earnings potential for Brazauaro shareholders. The key results of the 2010 PEA and comparable figures from 2007 were initially announced on February 2, 2010 and include: 2007 PEA 2010 PEA -------- -------- Gold Price/Oz $550/$900 $900 Oz Produced 1.597M 1.735M Average Production Oz 123,000/YR 145,000/YR Operating Cash Cost/Oz $353 $490 Initial CAPEX $128M $239M LOM CAPEX $27M $83M Payback Period 8.25 YRS 6.25 YRS IRR 9.6%/34.2% 11.9% 0% NPV $120M/$580M $297M 5% NPV $42M/$357M $129M Brazauro noted potential increases in value as follow: - Brazauro management applied its project development skills and commercial contacts to the PEA results to analyze the project's sensitivity to power costs of $0.045/kWhr and unit mining costs of $1.34/tonne - as compared with the PEA assumptions of $0.095 and $1.44, respectively. Management believes both costs are achievable and would result in a cash cost of $432/ounce, post-tax IRR of 15.7%, and a 5% NPV of $198 million. - An average gold price of $1100 per ounce increases the internal rate of return to 20.6% with net present values of $585 million at a 0% discount rate and $328 million at 5%. "Completion of this PEA for Tocantinzinho is an important milestone in bringing this highly promising deposit in to production. While drilling is continuing on the property the PEA results confirm the viability and potential of the project," said Brazauro President and COO Jim Komadina.
