Sona Releases New Blackdome Mine Resource Estimate

Thursday, May 6th, 2010

Sona Resources Corp. is pleased to announce that it has received a new NI 43-101 compliant resource estimate, summarized below, for its Blackdome Gold Mine in British Columbia. The resource estimate was prepared by SRK Consulting (Canada) Inc.
Mineral Resource Statement, Blackdome Gold Mine, SRK Consulting, March 31, 2010
Category, Quantity(tonnes), Grade gold(g/t), Gradesilver(g/t), Gold(oz), Silver(oz)
Indicated 144,500 11.29 50.01 52,600 232,300
Inferred 90,600 8.79 18.81 25,900 54,400
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 current estimate brings the Blackdome resource to NI 43-101 standards. It shows an increase of approximately 50 percent from the 1999 historical mine resource estimate of 124,000 tonnes, grading 12.8g Au/t and 33.7g Ag/t, for a total of 50,834 ounces of gold and 134,386 ounces of silver. 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 mineral resource statement was prepared by SRK 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 March 31, 2010. The mineral resources were reported at a cut-off grade of 5.0g Au/t, assuming an underground mining scenario, a gold price of US$1,000 per ounce, and 100 percent metallurgical recovery.
The resource estimate was completed by Dorota El-Rassi, P.Eng (PEO no. 100012348), 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 no demonstrated economic viability. All figures are rounded to reflect the relative accuracy of the estimate. A technical report prepared following the NI 43-101 and Form 43-101F1 guidelines will be filed on SEDAR within 45 days.
Exploration data used to evaluate the mineral resource for the Blackdome Gold Mine was provided in digital format by Sona as a Gemcom GEMS database containing drilling information for 909 boreholes (99,485 metres) and 127 trenches (850 metres). The database includes 13 surface boreholes (2,896 metres) drilled in 2007, 10 surface boreholes (2,015 metres) drilled in 2006, and 98 (8,605 metres) underground holes drilled by the previous project operator between 1986 and 1999.
The mineral resource statement was prepared by SRK using a geostatistical block modelling approach constrained by gold mineralization wireframes. Ten distinct auriferous vein wireframes (Vein 1, Vein 2, Vein 11, Vein 17, Vein 18, Vein 19, Giant, Watson, and the Redbird and Southwest Veins were generated from polylines digitized on vertical cross-sections spaced every 25 metres. These wireframes were used as hard boundaries to constrain metal grade estimation. SRK estimated gold grades into a block model (block size of 5.0 by 5.0 by 5.0 metres) using ordinary kriging and capped composite gold data. In the absence of specific gravity data, SRK used an average specific gravity of 2.65 for converting quartz vein volumes into tonnages. SRK is of the opinion that the mineral resource for the Blackdome Gold Mine is appropriately classified as an indicated and inferred mineral resource within the meaning of CIM Definition Standards for Mineral Resources and Mineral Reserves (December 2005).
A 5,000-metre surface diamond drilling program to target extensions of known auriferous veins is planned for summer 2010, to further expand the gold resource.
