QUEBEC - Vancouver-based AURIZON MINES has increased its resource estimate for the Lower Inter zone at its Casa Berardi gold mine 95 km north of LaSarre. The updated mineral resources are estimated at 973,000 tonnes averaging 11.6 g/t Au, or 361,200 oz in the indicated category and 43,000 tonnes averaging 5.6 g/t Au, for 7,800 oz in the inferred category. This represents a 59% gain in grade and a 30% gain in ounces from the previous estimate.
The Casa Berardi deposit is a vein-type deposit located close to the contact between the sedimentary basin sequence and the volcanic basement. The deposit extends for a 5.0-km strike along the Casa Berardi Fault system. More specifically, the Lower Inter zone is a flat-lying vein located in the western part of the body, 600 to 1,000 metres from the existing shaft. The vein fills a void defined by two graphitic faults known as the Casa Berardi and Lower Inter faults.
The newest resource estimate for the Joanna property in the middle of the Cadillac Break 20 km east of Rouyn-Noranda is also encouraging. Aurizon notes that based on data provided by previous owners, the property contains 7.1 million tonnes averaging 1.8 g/t Au, or 411,400 oz in the indicated category and 24.5 million tonnes averaging 1.6 g/t Au, for 1.26 million oz in the inferred category. This represents a gain of 33% in the indicated category and 15% in the inferred category from the previous estimates announced on March 28, 2007. Aurizon has an option to earn a 100% interest, subject to a 2% NSR.
