TORONTO, ONTARIO--(Marketwired - Jun 15, 2015) - Argonaut Gold Inc. (AR.TO) (the "Company", "Argonaut Gold" or "Argonaut") is pleased to provide an update on the 2015 drill campaign on ground being acquired from Richmont adjacent to the Magino deposit, located near Wawa, Ontario.

Drilling on the newly acquired Richmont ground was initiated in order to explore the eastern extension of Magino deposit mineralization. The latest mineral resource statement for the Magino deposit hosts an indicated mineral resource of 127.8 million tonnes at 1.01 g/t gold for 4.2 million ounces and an additional inferred mineral resource of 30.0 million tonnes at 1.08 g/t gold for 1.0 million ounces. (The current drilling as detailed in this release has not been incorporated into an updated resource.)

Peter Dougherty, President and CEO of Argonaut Gold stated: "I am pleased with the progress the Company is making at Magino. This project hits on so many of the key evaluation metrics we look for in a project. It is a multi-million ounce deposit that greatly benefits from the advantages that come with being located in one of the top mining countries of the world. These drill results show both extended mineralization and higher grades. As we continue to test the extensions of the deposit, we are excited about the potential to increase the resource and value of this project."

Richmont Extension highlights:

The Company completed 12 wide spaced NQ core holes totaling 4,067 metres. This drilling was positioned to explore mineralization along the eastern projection of the Magino deposit. Drilling identified mineral potential over more than 250 additional meters from the prior property boundary and successfully demonstrated eastern continuity to the Magino deposit. Listed below are a summary of key drill results and map of drill hole placement:

Vice President of Exploration, Tom Burkhart said, "We are excited and encouraged by the drilling results from the Richmont extension zone. As predicted we extended mineralization easterly an additional 250 meters. We look forward to continuing to advance this project and incorporating this information into and updated mineral resource."

Path Forward

Additional infill drilling has been completed in the heart of the Magino deposit to improve our understanding of the mineralization surrounding the historic underground mined. This data is being assayed and compiled and is expected to be released early in the third quarter. The 2015 Magino drilling results will be incorporated into an updated resource and preliminary economic assessment for the project which is expected to be released in late 2015.

Mr. Thomas Burkhart, Argonaut's Vice President of Exploration is the Company's Qualified Person responsible for the contents of this press release and has reviewed approved the information in the release pursuant to National Instrument 43-101("NI 43-101"). For further information on the Magino Gold Project please refer to the reports as listed below on the Company's website www.argonautgold.com or on www.sedar.com:

Argonaut Gold used Activation Laboratories in Thunder Bay as the primary laboratory for its analysis. The samples were analysed using a fire assay method with a 50 g pulp size. All results greater than 5 gpt were subsequently analysed using a metallic screen. Samples that were strongly mineralized or altered were selected for additional metallic screen analysis. Certified reference materials (standards) or blanks were inserted every 10 samples and preparation duplicates were taken every 50 samples.

Cautionary Note Regarding Forward-looking Statements

This press release contains certain "forward-looking statements" and "forward-looking information" under applicable Canadian securities laws concerning the business, operations and financial performance and condition of Argonaut Gold Inc. ("Argonaut" or "Argonaut Gold"). Forward-looking statements and forward-looking information include, but are not limited to, statements with respect to estimated production and mine life of the various mineral projects of Argonaut; the estimation of mineral reserves and resources; success of exploration activities; the realization of mineral reserve estimates; the timing and amount of estimated future production; costs of production; and financial impact of completed acquisitions; the benefits of the development potential of the properties of Argonaut; the future price of gold, copper, and silver; synergies; and currency exchange rate fluctuations. Except for statements of historical fact relating to Argonaut, certain information contained herein constitutes forward-looking statements. Forward-looking statements are frequently characterized by words such as "plan," "expect," "project," "intend," "believe," "anticipate", "estimate" and other similar words, or statements that certain events or conditions "may" or "will" occur. Forward-looking statements are based on the opinions and estimates of management at the date the statements are made, and are based on a number of assumptions and subject to a variety of risks and uncertainties and other factors that could cause actual events or results to differ materially from those projected in the forward-looking statements. Many of these assumptions are based on factors and events that are not within the control of Argonaut and there is no assurance they will prove to be correct.

Factors that could cause actual results to vary materially from results anticipated by such forward-looking statements include variations in ore grade or recovery rates, changes in project parameters, changes in market conditions, risks relating to international operations, fluctuating metal prices and currency exchange rates, the possibility of project cost overruns or unanticipated costs and expenses, labour disputes and other risks of the mining industry, failure of plant, equipment or processes to operate as anticipated.

These factors are discussed in greater detail in Argonaut's most recent Annual Information Form and in the most recent Management Discussion and Analysis filed on SEDAR, which also provide additional general assumptions in connection with these statements. Argonaut cautions that the foregoing list of important factors is not exhaustive. Investors and others who base themselves on forward-looking statements should carefully consider the above factors as well as the uncertainties they represent and the risk they entail.

Argonaut undertakes no obligation to update forward-looking statements if circumstances or management's estimates or opinions should change except as required by applicable securities laws. The reader is cautioned not to place undue reliance on forward-looking statements. Statements concerning mineral reserve and resource estimates may also be deemed to constitute forward-looking statements to the extent they involve estimates of the mineralization that will be encountered if the property is developed.
