New Discoveries at Aurcana's La Negra Mine Indicates the Presence of Gold
February 13, 2013 --
Vancouver, BC, February 11, 2013- Aurcana Corporation ("Aurcana" or the "Company") (TSXV: AUN, OTCQX: AUNFF) is pleased to announce the results of the 2012 surface mapping program at the La Negra Mine.
Mr. Lenic Rodriguez, Aurcana's President & CEO, states:" We are very pleased to report today significant exploration results and new discoveries at La Negra. The presence of gold associated with strong silver, zinc and lead values in new areas tested is very encouraging. While historically gold production has not been a major source of revenue at La Negra, and the potential economic significance of these results is not known, these results are of strong interest to us. The ramp-up at Shafter, increase in mining capacity at La Negra and excellent exploration results, are indeed exciting times for Aurcana."
• Zona Aurifera I, returned strong assay values including:
o 15.3 gm/t Au and 261 gm/t Ag;
o 12 gm/t Au and 105 gm/t Ag;
o 10.0 gm/t Au and 381 gm/t Ag;
• Zona Aurifera II also returned strong assay values including:
o 2.8 gm/t Au and 229 gm/t Ag;
o 2.4 gm/t Au and 307 gm/t Ag;
o 2.8 gm/t Au and 95 gm/t Ag;
La Negra Exploration Program
The exploration program has outlined six exploration targets. All areas indicate some presence of gold, with two zones, designated Aurifera I and II, returning the greatest number of gold values per total number of samples collected (32% and 29%). Assay values range from 0.2 gm/t to 15.3 gm/t Au and are associated with strong silver, lead and zinc values, as well as geochemically anomalous bismuth and arsenic. All are within skarn similar to that currently being mined and several have favorable metal assemblages including copper, lead, zinc and most notably silver and gold.
Current detailed mapping and sampling are focused on the Aurifera I and II zones and on the El Alacran Norte zone to determine size and average grade. The Aurifera II zone has not been fully delimited to date.
The location of the Aurifera I and II zones is at the southern contact of the main diorite intrusion. Oxidized, fracture controlled mineralization is hosted in massive skarn.
El Alacran Norte is located on the northern contact of the main diorite intrusion. Oxidized Ag-Pb-Zn-Cu mineralization is hosted in skarn horizons.
The La Negra mine was initially in production from 1971 to 2000, then acquired form Penoles and placed back into production by Aurcana in 2007. The mine is accessed through portals at the base of a mountain, and the mineral resource is established by underground diamond drilling programs. The potential for extensions of these resources in the upper portion of the mountain and the deep extensions have not been pursued since Aurcana acquired the property. As such, these results are seen to be a step towards recognizing the greater potential of the La Negra mineralized zones.

Quality Assurance Quality Control
One meter chip samples were collected from fresh rock after oxidized surface material was removed. For every 10 samples a blank of un-mineralized country rock and a duplicate sample was inserted. Sample locations were marked with metal tags and were photographed. Samples were bagged and sent to the ALS Prep Lab in Mexico. Pulps were submitted to the ALS Chemex Laboratory in Vancouver and analyzed for 49 elements (ME- M41). High copper, lead, zinc and silver values were re-analyzed using ore grade analysis. Gold values have not been confirmed by Fire Assay.
Blanks and duplicates were checked for conformity with lab results.

This news release contains certain forward-looking statements, including statements regarding forecast silver production, silver grades, recoveries, potential mineralization, exploration result, future plans and objectives of the Company and the business and anticipated financial performance of the Company. These statements are forward-looking statements that involve various risks and uncertainties. These forward-looking statements include, but are not limited to, statements with respect to mining and processing of mined ore, achieving projected recovery rates, anticipated production rates and mine life, operating efficiencies, costs and expenditures, changes in mineral resources and conversion of mineral resources to proven and probable reserves, and other information that is based on forecasts of future operational or financial results, estimates of amounts not yet determinable and assumptions of management.
Exploration results that include geophysics, sampling and drill results on wide spacings may not be indicative of the occurrence of a mineral deposit. Such results do not provide assurance that further work will establish sufficient grade, continuity, metallurgical characteristics and economic potential to be classified as a category of mineral resource. A mineral resource which is classified as inferred” or indicated” has a great amount of uncertainty as to its existence and economic and legal feasibility. It cannot be assumed that any or part of an indicated mineral resource” or inferred mineral resource” will ever be upgraded to a higher category of resource. Investors are cautioned not to assume that all or any part of mineral deposits in these categories will ever be converted into proven and probable reserves.
