Aurcana Discovers New Silver Mineralization at Depth at La Negra Mine
|VANCOUVER, BRITISH COLUMBIA - (Marketwire - December 13, 2011) - Aurcana Corporation (TSX VENTURE:AUN)(OTCQX:AUNFF) ("Aurcana" or the "Company") is pleased to announce that underground drilling at the La Negra Silver-Copper-Lead-Zinc Mine, located in Querataro State, Mexico, has intersected new deeper mineralization below the 1920 m. level of the mine. This is the first time Aurcana has indentified significant amounts of mineralization at this depth.|
Strong silver and copper values were encountered in holes IBX-02, 03, 04, 06, and 07 with the highest grade values ranging from 120/t Ag to 405gm/t/Ag and 1.18% Cu to 3.12% Cu.
The La Negra deposits are characterized by chimney and manto style deposits in skarn zones formed near the contact of limestone units and a large intrusive body.
One of Aurcana's key objectives at La Negra is to continue replacing and expanding the ore resources through a combination of underground drilling and development. Ten holes were drilled from four locations to trace the strike and dip extents of several moderately dipping, well mineralized beds (mantos) in the Breccia Norte Zone.
Lenic Rodriguez, President & CEO comments, "Annual exploration and development programs have continued to successfully replace ore as it is mined, since the operation was restarted, supporting successive mine production expansions from 1,000 tpd to 1500 tpd and then to 2000 tpd. Aurcana is modernizing its database in anticipation of a new 43-101 compliant reserve and resource estimate in early 2012."
From the following table, multiple intercepts in holes IBX 01, IBX 03, and IBX 05 suggest two to three mineralized mantos. Additional drilling and development is planned to define the extents of the mineralized mantos. The La Negra operation has adopted and is applying NI 43-101 standards in order to certify a number of mineralized zones including the Breccia Norte. Currently only 3 of 28 known mineralized deposits have NI 43-101 compliant resources, however, 86% of the ore mined in 2011 came from historical resources which are non-compliant.
Selected intersected mineralized widths range from 2.15m to 51.45m with an average intersected width of 15.00 m and a length weighted average grade of 87gm/t Ag, 0.17% Pb, 2.00% Zn, 1,10% Cu. (table below)

The underground drilling utilized company owned and operated drills and core was assayed by the mine laboratory which is operated by Minera La Negra personnel. Analytical QA-QC controls are maintained through the use of duplicates, blanks, and commercial standards.
