Argonaut Gold Inc. (TSX: AR) is pleased to announce that drill hole MA21-070 has intersected a core length of 7.0m at 13.3 g/t Au approximately 1.5 kilometres west from the border between the Magino property and the Island Gold mine, as a follow-up drill hole to previously announced drill intercept MA20-057 which encountered 10.0m at 19.0 g/t Au in the South Zone at its 100% owned Magino property in Ontario, Canada (see press release dated January 20, 2021).
Recent highlights include:

The 2021 drilling program is primarily focused on tightening the drill spacing to approximately 40 m (upper portion) and 80 m (lower portion) within the Elbow Zone from the bottom of the planned pit to a vertical depth from surface of around 1,000 m. The secondary focus of the program is to continue to drill test previously discovered high-grade gold structures within the South Zone, Central Zone, Scotland Zone, #42 Zone and Sandy Zone as well as other prospective showings located elsewhere on the Magino property. Argonaut plans to drill approximately 25,000 metres on these targets this year, is currently drilling with four diamond drill rigs and anticipates completing the program during the fourth quarter of 2021.
Pete Dougherty, President and CEO stated: “The goal of our 2021 program is to tighten the drill spacing within the Elbow Zone to the point where we can evaluate the resource potential of this important structure. Due to the exploration team’s success to date at discovering high-grade gold structures below and adjacent to the planned open pit, we have numerous highly prospective drill targets.”
The South Zone follows the southern contact of the Webb Lake Stock (granodiorite rocks) and volcanic rocks (Figure 2). Drill holes MA21-070 (7.0m at 13.3 g/t Au and 8.0 m at 5.1 g/t Au) and MA21-071 (9.5m at 3.7 g/t Au) were designed to test the South Zone as follow up holes to previously reported intercepts MA20-057 (10.0m at 19.0 g/t Au) and MA12-424 (21.0 m at 11.0 g/t Au including 7.6m at 29.4 g/t Au). This zone contains two parallel vein systems within a structure that has an approximate true width of 25 metres that mimics the trend of a nearby aplite dyke, appears to transect eastward into the volcanic rock package for an apparent strike length of 1.5 km to the eastern property boundary. Drill holes MA20-057 and MA20-070 intersected the gold-bearing vein system down-plunge for an estimated apparent true width ranging between 3.4m to 4.8m. With only three holes completed at depth to define this zone, additional drilling perpendicular to the vein system is required to accurately define the width of the vein systems that comprise the South Zone.

Infill definition drilling of the Elbow Zone continues to define numerous high grade gold zones within this steeply east plunging structure where oriented core and the collection of structural measurements on significant vein systems continues to test the continuity of gold mineralized veins that define this important zone. Close to 17,000 metres of drilling is still needed to complete the Phase 1 definition drilling program. Drilling within the Elbow Zone continues to intersect exciting gold values (MA21-063 of 8.0 m at 7.7 g/t Au; MA21-067 of 2.0 m at 17.7 g/t Au) as presented on Figure 3 below.

Brian Arkell, Vice President of Exploration commented: “We are continuing to develop a better understanding on the structural controls on the high-grade mineralization at Magino and are now in the process of early-stage resource definition drilling on the Elbow Zone. With the extremely encouraging initial high-grade gold results at depth within the Elbow and South Zones, we are very excited about our success in defining a series of high-grade gold mineralized structures below the Magino planned open pit.”

Qualified Person Comments / Quality Control Procedures
The preparation of this press release was supervised and approved by Brian Arkell, Argonaut Gold’s Vice President Exploration and a Qualified Person under NI 43-101. Mr. Arkell also reviewed the diamond drilling, sampling, and on-site sample preparation procedures at Magino.
For sample analysis, the Company utilizes a system of Quality Assurance/Quality Control that includes insertion and verification of standards, blanks, and duplicates consistent with industry standards.
The Company has implemented a QA/QC program to ensure sampling and analysis of all exploration work is conducted in accordance with the CIM Exploration Best Practices Guidelines. The entire drill hole is sampled and tagged by geologic personnel. Cores are then photographed and sawn in half by experienced geotechnicians, placed in numbered plastic bags, and gathered in rice bags which are sealed with tamper-proof security tags under the supervision of the project geologists. The other half of the core is retained for future assay verification and/or metallurgical testing. Other QA/QC procedures include the insertion of coarse blanks and Canadian Reference Standards for every tenth sample in the sample stream. Samples are bagged, sealed with numbered security tags and shipped to the Activation Laboratories facility, Thunder Bay, Ontario, for sample preparation and assaying. The laboratory has its own QA/QC protocols, running standards, blanks, and duplicate samples in each batch stream. Gold analysis is conducted by lead collection, fire assay with a gravimetric finish on a 50-gram sample. Metallic screen fire assaying is now completed using a 1.0 kg sample and two 50 gm fire assays of the pass (-100 mesh) pulverized material on all samples containing visible gold. Check assays are conducted at a secondary ISO certified laboratory.
