TRANSCRIPT
• 3 hour drive north of Durango City, in the Sierra Madre Occidental, one of the world’s most prolific volcanic arcs for epithermal gold deposits and mines.
• Geological setting, structural disposition, widespread boiling textures, low-T alteration, and fluid inclusions indicate that the upper levels of the system are preserved.
• Limited exploration conducted by previous workers. Since acquisition in late 2009, Aurion systematically advanced the property with mapping, prospecting, soil geochemistry, SWIR alteration studies and hand trenching - this work has generated significant new targets.
• Ranked as 6th best mining jurisdiction in the world in 2010 by Fraser Institute, Mexico is the world’s largest producer of silver and its gold production has increased by 139% since 2005 (INEGI).

LA BANDERA: AURION’S FLAGSHIP PROPERTY
La Bandera is currently under option to AuRico Gold Inc. AuRico to spend $5 million over 3 years with a firm commitment to spend $1 million on La Bandera in 2011. 5000 metre drill now underway.
• La Bandera occupies the central 30 km of an >50 km long NW trending mineralized structural zone.
• Historic production 6 km north of La Bandera at Promontorio includes 250,000 t @ 20 g/t Au and 3500 g/t Ag.
• 10 km SE at Coneto, over 40 high-grade Ag-Au veins are currently being explored by Orex Minerals Inc. and its JV partner Fresnillo PLC.
• The 12,985 ha La Bandera property envelopes a >20 km long, 40 to 150 m wide epithermal gold-rich vein system associated with rhyolite flow dome complexes.
• La Bandera was originally discovered by La Cuesta, co-discoverers of Camino Rojo in Zacatecas, Mexico (3.4 M oz Au, 60.7 M oz Ag; Goldcorp website).

Vision Strategy Performance
• Previous workers focused on the southern part of the La Bandera Trend, culminating with 7 drill holes. Best intercepts came from DDH BNW-5: 0.6 g/t Au over 15.5 m including 2.2 g/t over 0.7 m. No follow-up drill work had been done until now.
• Aurion’s work on the northern half of the property outlined an open-ended 2300 m long by 300 m wide gold-in-soil-and-rock anomaly. Soil values range up to 2 g/t Au. Rock samples assayed up to 74 and 48 g/t Au. Visible Gold was identified at three localities.
• Anomalous gold values are coincident with robust alteration - dominated by low-T clays (illite, smectite) and widely spaced quartz veinlets with epithermal boiling textures.
• Vein textures, alteration and geochemistry are all consistent with upper levels of an epithermal system indicating that the system is preserved and essentially uneroded.
• La Bandera is under option to AuRico Gold Inc. AuRico to spend $5 million over 3 years, including a $1 million firm commitment for 2011. A >5000 m drill program is now underway.
