Argonaut Gold Provides Update on San Agustin Project; Potential 50% Resource Increase

Drilling Increases Mineralized Footprint With Potential 50% Increase Over Existing Resource. Environmental Permit has Been Submitted.

TORONTO, ONTARIO--(Marketwired - July 6, 2015) - Argonaut Gold Inc. (TSX:AR) ("Argonaut", "Argonaut Gold" or the "Company"), is pleased to provide a drilling update for its 100% owned San Agustin project. The project is located just 10 kilometres southwest from the Company's El Castillo Mine ("El Castillo") in Durango, Mexico. The Company completed a Preliminary Economic Assessment ("PEA") on the project in February, 2015. The San Agustin PEA resulted in a pit-constrained indicated resource of 845,000 gold ounces and 28 million silver ounces contained in 82.2 million tonnes of material at a grade of 0.32 grams per tonne ("g/t") gold and 10.7 g/t silver, for a total of 1,280,000 gold equivalent ounces. The gold equivalent ounces are calculated utilizing a 65:1 gold price to silver price ratio and does not incorporate the recovery differential between gold and silver.

The Company continues to better define the overall economic potential of the project. In addition to detailed sampling and geologic mapping, the Company is utilizing induced polarization (IP) and magnetic studies to prioritize target areas. Thirty one wide spaced RC holes (5,277 meters) were completed with most drilling positioned to test the northwest extension of the mineralized footprint. This expansion drilling was accomplished subsequent to the PEA and is not contained therein. The work completed thus far indicates potential to expand mineralization over an additional 1,000 metres, with the potential for a 50% increase in the existing resource area. Additional work will also be done on the Consejo 1 claim, acquired in 2014, which sits adjacent to the existing claims and shows potential for structurally controlled high-grade mineralization. The company has undertaken additional step-out drilling during the second quarter of 2015.

CEO Commentary

Pete Dougherty, President and CEO of Argonaut Gold said "The San Agustin project is a very exciting project for Argonaut. Due the close proximity to our El Castillo operation, this is a natural future extension of the El Castillo mine. The work completed to date, indicates the ability to further expand the known resource area. The proximity of San Agustin to El Castillo and the current exploration work indicating that the resource may be much larger than currently reported with a potential of improved economics."

San Agustin Expansion Drilling

Drilling completed thus far along the northwest extension supports the potential to significantly expand shallow oxide gold mineralization upwards of 1,000 metres northwest of the current resource. Results from this wide-spaced drilling include: DH-242, 0.27 g/t Au over 24.4 m, DH 251, 0.25 g/t Au over 32.0 m and DH-269 0.38 g/t Au over 16.8 m. Going forward the Company expects to complete additional in-fill and step-out drilling in these known areas of mineralization.

In the following map, drill holes noted by the larger dots are listed in the accompanying table; the smaller red dots contain greater than 25 meters of near-surface oxide mineralization grading over 0.15 g/t gold.

The current PEA for San Agustin included 271 RC drill holes totaling 30,043 meters completed in 2014 by Argonaut. This reported resource makes up the southeastern portion of a much larger mineralized footprint on the project which offers significant expansion potential. A strong network of fractures control mineralization as displayed in the following geologic map.

Mapped structural features are noted in blue.

Property Structural Features:

The Company has compiled soil sampling and IP geophysics on the property. The following soil map (left side) notes wide distribution of anomalous gold. The white dashed line indicates gold in soil values of over 100 ppb. The IP map on the right identifies a strong chargeability signature over the resource and a similar anomaly exists to the northwest that remains to be tested. The strong IP is thought to be an indication of underlying sulfide mineralization. The collation of information from soil, structure and IP are valuable in prioritizing the Company's ongoing exploration program.

Tom Burkhart, Argonaut Gold's Vice President of Exploration said "San Agustin is geologically very similar to El Castillo. We have a high comfort level with the deposit, and our ability to expand the resource. The work completed thus far on the project supports the potential to significantly expand the San Agustin gold-silver resource. The Company currently has permits in place for an additional 220 drill holes and drilling continues on the project."

The above leapfrog diagram depicts the trends of possible mineralization beyond the current resource area. It is clear that the wide-spaced drilling completed thus far to the northwest is defining a strong northwest extension of gold mineralization. The Company's ongoing exploration priority is to fill-in this potential expansion area.

Path way forward:

The Company is in the process of acquiring the necessary surface rights for the project. The Company has submitted the Environmental Impact Statement (Manifesto Impacto Ambiental) and this process is expected to take between six and nine months. The Company embarked on an additional drill program to continue to test the extent of mineralization on the property. The Company expects to complete this over the summer and to compile an updated project assessment by the end of the year.

Qualified Person, Quality Control and Mineral Properties Reports

Technical information included in this release was supervised and approved by Thomas Burkhart, Argonaut Gold's Vice President of Exploration, and a Qualified Person under National Instrument ("NI") 43-101.

RC drill cuttings are split on the drill rig and 1/4 of a 1.52 meter drill interval is collected for assay. The samples are picked up by ALS Minerals at the project site and transported by secure truck to their sample prep facility in Zacatecas, Mexico. Prepared sample pulps are shipped by air to the ALS Analytical Lab in Vancouver. The assay procedure on each sample is a Fire Assay using a 30 gram charge followed by an atomic absorption analysis (FF-AA). The Company uses Industry standard QA/QC procedures including inserting alternating standards, blanks and duplicates as every 10th sample. This results in every 30 samples having a blank, a standard and a duplicate.
