Sona Releases New Blackdome Tailings Resource Estimate
Sona Releases New Blackdome Tailings Resource Estimate
Resource Amenable for Recovery at Blackdome Mill
VANCOUVER – Sona Resources Corp. (the “Company” or “Sona”; TSXV – SYS, Frankfurt-QS7) is pleased to announce that it has received a new NI 43-101 compliant inferred resource estimate for the Blackdome Gold Mine (“Blackdome”) tailings impoundment of 298,389 tonnes of tailings, grading 1.47g Au/t and containing 14,145 ounces of gold at a cut-off grade of 0.5g Au/t. The resource estimate and the NI 43-101 report were prepared by Geoquest Consulting Ltd. (“Geoquest”) and Micon International Ltd. (“Micon”). In making the announcement today, John Thompson, Sona’s president and CEO said, “This is one more important step toward achieving our goal of commencing full-scale production at the Blackdome mill by 2013.”
The 18,500-hectare Blackdome Gold Mine is located in the Clinton Mining District, approximately 250 kilometres north of Vancouver. The site contains a fully permitted flotation and gravity mill. From 1986 to 1991, it treated 340,000 tonnes of ore at a mill head grade of 20g Au/t, producing 225,000 ounces of gold over five years.
The flotation reject tailings are fine silica sand with some clay-like slimy fractions containing less than 0.02 percent sulphur. Preliminary test work for leaching at SGS Lakefield, interpreted by Innovat Ltd., indicates a recovery of over 90 percent of the gold from the tailings pond. It has suggested that tailings from renewed production at Blackdome can be placed as paste residue or dry stacked away from the tailings pond, allowing for the possible mining and recovery of the gold contained within the old tailings. Additional metallurgical test work is required to fine-tune the disposal method for potential new tailings.
The mineral resource statement was prepared by Micon in accordance with Canadian Securities Administrators NI 43-101. Mineral resources have been estimated in conformity with generally accepted CIM “Estimation of Mineral Resource and Mineral Reserves Best Practices” guidelines. The effective date of the mineral resource statement is April 3, 2010, reported at a cut-off grade of 0.5g Au/t.
The resource estimate was completed by David Makepeace, P.Eng. of Micon, an independent qualified person as defined in NI 43-101, who has reviewed the technical information presented herein. Mineral resources are not mineral reserves and have not demonstrated economic viability. All figures are rounded to reflect the relative accuracy of the estimate. A technical report prepared following NI 43-101 and Form 43-101F1 guidelines will be filed on SEDAR.
Exploration data used to evaluate the mineral resources for the Blackdome tailings was provided in digital format by Geoquest to Micon as a database containing drilling information collected in 2002 for 51 vertical boreholes (314 metres) taken from lines 15 metres apart.
The Mineral Resource estimate was prepared by Micon using a geostatistical block modelling approach using Surpac software. A wireframe of the tailings pond was constructed based on the Geoquest drill hole database and the Knight Piesold geotechnical data of the dam configuration. This wireframe was used as a hard boundary constraint during the estimation process. Micon estimated gold grades into a block model with a nominal sub-block maximum size of 5 x 5 x 2 meters using Inverse Distance cubed (ID3) method. Micon used an average specific gravity of 2.6 for the old tailings based on Knight Piesold data. Micon is of the opinion that the Mineral Resources for the Blackdome Tailings Project are appropriately classified as Inferred Mineral Resource within the meaning of CIM Definition Standards for Mineral Resources and Mineral Reserves (December 2005).
About Sona Resources Corp.
Since its inception in 1990, Sona has engaged in exploration activities at its mineral properties in Canada and the United States, as well as small-scale gold production at its flagship property, the 100 percent owned Blackdome Gold Mine, in south-central British Columbia. At its 100 percent owned Elizabeth Gold Property, 30 kilometres south of the Blackdome Gold Mine, Sona has outlined an inferred gold resource of 522,900 tonnes grading 12.3g Au/t, containing 206,100 ounces of gold (news release of June 8, 2009). Sona aims to bring the Blackdome mill back into production over the next three years, with feed from the former-producing Blackdome Gold Mine and the Elizabeth Gold Property.
Sona holds a 100 percent interest in two other promising properties: The Callaghan Project is located in Nevada, within 80 kilometres of several producing mines, and is underlain by the Roberts Mountain Thrust, a major structural setting for gold deposits. The Montgolfier Project is located in Quebec, 40 kilometres east of the multimillion-ounce Casa Berardi Mine gold deposit.
