47.4 Million Ounce Silver Resource at Shafter Silver Mine Confirmed by 43-101

July 31, 2008

Aurcana Corporation ("Aurcana" or the "Company") is pleased to announce the release of a N.I. 43-101 compliant resource estimate on the 100% owned Shafter silver mine located in south-west Texas. The report was prepared by Tetra Tech Inc., of Golden Colorado and the full report can be viewed on the Aurcana website ( or on Sedar ( Upon review by Aurcana, when considering the current strong silver prices, an economic cut off of four ounces per ton was calculated for use in a pre-feasibility study. The result is an increase of 15% in the total resource to 47.4 million ounces of silver, as compared to our previous release (April 2, 2008, Aurcana Acquires Near Term Silver Production Project) which stated an historic resource of 41.2 million ounces using a five ounce per ton cut off.

The pre-feasibility study will select the mining method that will be used to optimize production capacity and maximize the project's economic return. The study will investigate the use of a decline to access the deposit, and mechanized room and pillar extraction. The decline will facilitate the efficient movement of supplies and large equipment for production and will allow the existing shaft to be dedicated to hoisting ore for the nearby mill. Initial calculations indicate that daily production could be sustained at a rate of up to 1,500 tons per day.

Silver was mined in the Shafter region from 1883 until 1942, when the mine was closed, not from lack of ore, but by the War Act. Historically reported total production during that period was 35 million ounces of silver from 2.3 million tons of ore, at an average grade of 15.24 ounces per ton.
Aurcana acquired the Shafter silver mine in July, 2008. All nec¬essary infrastructure is in place with a major power line and paved highway crossing the property, an electrical sub-station on site, a 1,050 foot shaft serviced by a 80 ton per hour hoist and 5,100 feet of underground develop¬ment.
