Aurogin Acquires Lupita Gold Deposit in Guatemala Possible Resource up to 540,000 Ounces

TORONTO, ONTARIO--(CCNMatthews - Sept. 20, 2005) - Aurogin Resources Ltd. ("Aurogin")(TSX VENTURE:AUQ) is pleased to announce that it has entered into an option agreement to earn a 70% interest in the Lupita gold deposit 600 metres west of Aurogin's El Sastre Gold deposit 30 km north-east of Guatemala City, Guatemala. To earn its 70%, Aurogin must spend $900,000 on exploration and pay the vendors $360,000 in cash and issue 800,000 shares by the end of 2008.

POSSIBLE DEPOSIT SIZE

While the current database is not detailed enough to quantify gold resources as defined in National Instrument 43-101, Aurogin management believes drill results have identified the potential for the area to host a possible mineral deposit on which, with additional detailed exploration drilling, a NI 43-101 compliant resource estimate can be prepared. The mineralized target reported here is open for extension both along strike and at depth. There is a high probability that the size of the possible mineral deposit can be increased significantly by additional drilling. The deposit, which was drilled by Goldfields Mining and Radius Gold Inc. between 2001 and 2003, has drill intercepts as follows: LWRC#1 - 25.9m @ 2.09g/t Au, LWRC#2 - 61.0m @ 1.28g/t Au, LWRC#3- 69.8m @ 1.00g/t Au, LWRC#4 - 135.6m @ 1.22g/t Au, LWRC#6 - 18.3m @ 1.39g/t Au, and LWRC#7 - 149.3m @ 0.77g/t Au.

The quantity and grade of a possible mineral deposit at Lupita could range from 7.3 to 13.9 million tonnes grading 1.1 to 1.7 g/t gold based on estimates made by Aurogin staff. Total gold content estimates range from 270,000 to 540,000 ounces. Over 900 meters of reverse circulation drilling from 7 drill holes were used in the estimates. Over 500 surface chip sample assays were used to define the outcrop of the deposit. A drill plan and cross sections through the deposit are available on the Aurogin website www.auroginresources.com. The potential quantity and grade given here is conceptual in nature in that there has been insufficient exploration data to define a NI 43-101 mineral resource, and it is uncertain if further exploration will result in the discovery of such a resource on the property.

MINERALIZATION

The Lupita Zone consists of hydrothermal quartz with disseminated pyrite and arsenopyrite in carbonaceous phyllites. Amphibolite schist hanging wall rocks are unmineralized. The Lupita Zone is located approximately 600 meters west of the Sastre Zone along the northeast-facing slope of a ridge. The mineralized zone has been traced along this ridge in trenches and outcrops. Hand-dug trenches in the Lupita Zone returned average values in the 1 to 2 g/t Au range over thicknesses of up to 30 meters. The flat lying Lupita Zone target measures 300 by 300 meters and remains open to extension. Significant intervals encountered in the trenches include: 2.46g/t Au over 37.3 meters, 2.09g/t Au over 34.6 meters, and 2.01g/t Au over 19.3 meters. The Lupita Zone extends into the Chorro area approximately 400 meters west. Trenching, prospecting and rock sampling indicates that it could extend an additional 400 meters to the west. Significant trench intersections include: 1.71g/t Au over 7.9 meters, 1.12g/t Au over 11.5 meters, and 5.47g/t Au over 3.3 meters.

FUTURE PLANS

Aurogin plans to carry out additional "step-out" drilling to further evaluate the size of the deposit as well as "in-fill" drilling to provide sufficient data to make a NI 43-101 compliant resource estimate which will form the basis of a scoping study.

"We are particularly excited with the proximity of Lupita to El Sastre and believe that El Sastre's infrastructure will significantly enhance the economic potential of Lupita." said John Paterson, P.Eng, President and CEO of Aurogin.

Aurogin is currently completing detailed engineering on El Sastre, and is in discussions with several parties regarding debt and equity financing. Aurogin was granted environmental approval for El Sastre in August, 2005 and production from the open pit mine is scheduled to start in 2006 at a rate of 20,000 oz/yr, increasing to 40,000 oz/yr as more resources are defined.

QUALITY ASSURANCE/QUALITY CONTROL

Preparation and analyses for all samples has been completed by independent commercial laboratories using industry standard fire assay and/or wet geochemical procedures. Sample shipments included standards and duplicates as part of on-going quality control programs. Assaying was carried out by Rocky Mountain Geochemical / BSI Inspectorate Laboratories ("BSI") in Guatemala City, Guatemala. BSI is a subsidiary of Inspectorate America Corporation, which is ISO 9002-certified. Samples are prepared by BSI's staff at their preparation facility in Guatemala City and pulps were flown to Reno, Nevada for all analytical work. Rock samples were delivered to BSI's preparation lab in Guatemala City where they were crushed to -10 mesh and a 300g sub-sample was pulverized to -200 mesh and shipped to their Reno facility. In Reno this sub-sample was assayed for Au by a 30g FA/AA and for 30 additional elements by aqua regia ICP analysis. All rock samples returning greater than 1.0 g/t Au were subsequently re-assayed by 30g fire assay (FA) with gravimetric finish. John H. Paterson, P.Eng. is the Qualified Person on this project.
