Aurion Provides La Bandera Update

MT PEARL, NEWFOUNDLAND--(Marketwire - Sept. 21, 2010) - Aurion Resources Ltd. ("Aurion") (TSX VENTURE:AU) is pleased to provide the following update on recent work at the La Bandera gold-silver project in Durango State, Mexico. 

Ongoing field programs, including mapping, prospecting, soil and rock geochemical sampling, hand-trenching and alteration studies, continue to outline a large, un-eroded, volcanic-hosted gold-bearing epithermal system. 

Recently received soil geochemical results have outlined new targets including the extension of the previously reported 1,300 metres ("m") long by up to 300 m wide Au-in-soil geochemical anomaly, by an additional 1000 m to the southeast. This open-ended anomaly near the northern end of the property is now greater than 2300 m long and 300 m wide. Individual soil samples collected on 50-100 m spaced lines at 25-50 m intervals, assayed from less than 2.0 parts per billion (ppb; 0.002 g/t) to up to 2.07 g/t Au, with 59 samples assaying greater than 50 ppb including thirteen assaying greater than 200 ppb. 

Also, occurring throughout the area underlain by the soil anomaly are numerous narrow (1-30 cm wide) quartz veins exhibiting classic epithermal boiling textures including extensive silica replacement of bladed calcite and colloform banding of silica, consistent with formation in the upper levels of an epithermal system. These veins are consistently anomalous in gold and select bedrock chip samples of these quartz veins assayed 73.7, 48.4, 9.7 and 7.2 g/t Au, as previously reported. Chip-channel sampling of hand-dug trenches over portions of the soil anomaly have also returned up to 10.0 g/t Au over 1.2 m. Visible gold has been observed in three localities and several small artisanal pits and mills are present. Recent alteration studies have also identified widespread clay alteration (illite, illite-smectite, kaolinite) along the La Bandera trend and coincident with this large, undrilled, soil geochemical anomaly. The extensive clay alteration and widely distributed gold-bearing veinlets exhibiting boiling textures are interpreted as forming near the upper terminus of a significant epithermal vein system. 

At the southern end of the property, newly discovered veins in bedrock have extended the system a further 2.0 km southeast of previously known extents. The veins are up to 1.5 m wide and individual bedrock samples have assayed up to 4.1 g/t Au. These veins also exhibit epithermal boiling textures.

The La Bandera epithermal gold vein system is now documented to extend over 20 kilometers. Mapping and relogging of core have documented the stratigraphic and structural position of the La Bandera trend mineralization in the upper portions of a structure controlling a regional scale monoclinal fault propagation fold. This setting, combined with extensive evidence of shallow level, gold mineralization is highly permissive for the existence of significant mineralization at depth.

 "The work we have done to date supports our interpretation that La Bandera represents the upper levels of a large, mineralized, epithermal system", stated Mike Basha, President and CEO of Aurion. "Moreover, the recent, model-driven, success at Ixtaca by Almaden Minerals drill-testing beneath the upper levels of a similar-type epithermal system, supports our initiative at La Bandera and further enhances its prospectivity. The next logical step is geophysics to further define drill targets".

Aurion is seeking joint venture partners to advance the property.


ALS Chemex, a certified commercial laboratory, performed the analytical testing at their facilities in Vancouver, BC. Samples were transported to a trucking company in Durango by Aurion personnel. The trucking company under contract to ALS Chemex transported the samples to the ALS Chemex prep. facility in Zacatecas. Gold analyses were by 30 gm fire assay with an ICP finish. Multielement analyses were by ICP. A quality assurance/quality control program is in place from sample collection through to laboratory analysis.
