Argonaut Gold Inc. Updates Drill Results From the El Castillo Resource Expansion Program Core Drilling Program Commences for Metallurgical Testing of Transition and Sulfide Ores
TORONTO, ONTARIO--(Marketwire - Oct. 12, 2010) - Argonaut Gold Inc. (TSX:AR) ("Argonaut" or the "Company") is pleased to provide an update regarding its 2010 resource expansion drill program at its 100 percent owned El Castillo gold mine in the State of Durango, Mexico. Following the successful Phase I drill program at El Castillo, Phase II of the drill program was initiated with two reverse circulation drill rigs. The Phase I drilling was positioned on approximately 100 meter centers and was designed to identify the extent of potential gold mineralization that expands to the south and east of the current El Castillo open-pit mining operation. Phase I encompassed 16,250 meters totaling 120 holes, and was completed in mid April. Immediately thereafter, Phase II drilling commenced on approximately 50 meter spacing within mineralized areas identified by Phase I. Total drilling from both phases includes more than 35,000 meters spanning over 280 holes. Additional infill drilling results, similar to current pit grades, are anticipated to be added into a measured category of an updated 43-101 Technical Report, that is scheduled for completion by year's end.

Drilling results have increased the mineralized envelope by approximately 500 meters to the south and 400 meters to the east, representing almost a 100% increase in dimensions over the existing $625 pit. We'll continue to employ an RVC drill to further test the property potential at El Castillo as it remains open in several areas of interest." Transition and Sulphide Ore An ongoing priority for the Company is to evaluate the economics of transition and sulphide ore zones that underlie the oxide resource, as this material potentially represents a significant increase in ore tonnages for the El Castillo operation. The company has committed to additional metallurgical testing with Kappes Cassidy Associates of Reno to assess the following: Phase I - Metallurgical testing of bulk samples from the mine. Phase II - Evaluation of the transition and sulphide ores. A 1,000 meter core drilling program is currently in progress to provide transition and sulfide samples for further metallurgical studies. The new transition and sulphide material will be assessed to evaluate the recoveries.

In regards to Argonaut's overall exploration program, Tom added "We look forward to initiating a drill program at our La Fortuna Project in the 4th quarter." Amalgamation of Argonaut Gold Inc.

Qualified Person Comments/Quality Control Procedures All drill-hole samples were composited at site into 1.5 meter intervals and split with 1/4 of the sample transported to ALS-Chemex's sample preparation lab in Zacatecas, Mexico. Pulps are prepared here and then sent to ALS-Chemex's Laboratories in Vancouver, Canada where gold assays are completed using a fire assay procedure with an Atomic Absorption Spectroscopy ("AAS") finish. Sixteen RVC drill holes were also selected for cyanide leach analysis with this work also completed by ALS Chemex at their Vancouver facility. The Company utilizes a system of check assays, sample duplicates and sample blanks consistent with industry standards. Preparation of this press release was supervised by Thomas Burkhart, Argonaut Gold's Vice President of Exploration and a Qualified Person under National Instrument 43-101. Mr. Burkhart also reviewed the reverse circulation drill program and on-site sample preparation procedures at El Castillo.
