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)
