Argonaut Gold Inc. (TSX: AR) is pleased to announce drill results from Phase Two of its drill campaign specifically targeting high-grade mineralization below the proposed pit at its 100% owned Magino property in Ontario, Canada, including 6.0 metres at 8.31 g/t Au, 1.0 metre of 48.50 g/t Au and 2.0 metres at 25.88 g/t Au.
The Phase Two program has focused on tightening drill spacing around high-grade intercepts encountered during the Phase One program at both the Elbow Zone and Central Zone. The results in this press release are from the Elbow Zone and the Company anticipates reporting results from the Central Zone once all assays have been received (Figure 1). To date, the Company has completed 54 diamond drill holes, including six (6) wedge holes, for a total of 34,852 metres of drilling in the Phase One and Phase Two programs.
The Phase One program discovered a number of high-grade veins over a widely spaced area beneath and adjacent to the Magino gold reserve. Drill spacing in this initial phase was up to 400 metres between holes and reached vertical depths up to 1,000 metres. Phase Two of the program utilized structural modeling from oriented core and optical televiewer measurements to focus on defining gold continuity within the high-grade shoots. In general, holes were designed to offset Phase One high-grade intercepts by approximately 40 metres. Results to date show promising gold grade continuity in the upper and deep portions of the Elbow Zone.
Recent highlights include:
Pete Dougherty, President and CEO stated: “We continue to intersect high-grade gold and more importantly, we are seeing promising high-grade continuity within the Elbow Zone where we have now tightened drill spacing averaging between 40 metres and 50 metres in two areas. We are anxiously awaiting results from Phase Two drilling in the Central Zone where, like results from the Elbow Zone, we continue to encounter visible gold.”
Table 1 below highlights select drill results from the Elbow Zone from the on-going Phase Two program. A three-dimensional model of the Magino deposit and the Elbow zone in relation to the proposed pit and property boundaries is available on the Company’s website at https://www.argonautgold.com/English/assets/drill-results/default.aspx

A detailed structural analysis was incorporated into the vein model for the Elbow Zone, where three veins contain high-grade gold mineralization. Normal and wedge drilling was then implemented to complete close-spaced offsets, nominally 40 metres, around three high-grade zones intersected in Phase One (Figures 1 and 2).
In the upper Elbow Zone, four additional holes were completed to test continuity around MA19-016 that returned 9.63 g/t Au over 14.0 m. A total of ten (10) holes have now been completed in Phases One and Two around hole 16 (Figure 3). All have intercepted significant gold values over estimated true widths (ETW) of 4.0 m to 15.0 m (Figure 3). High-grade values show good continuity throughout the zone as illustrated by hole MA20-041A which returned 4.86 g/t Au over 16.0 m core length, including a higher-grade portion running 14.09 g/t Au over 4.0 m and MA20-039 which returned 5.49 g/t Au over 6.0 m including 13.86 g/t Au over 2.0 m. Table 1 lists other significant intercepts.
A second area of continuity drill testing focused on the deeper part of the Elbow Zone to a vertical depth over 900 m from surface (Figure 4). The deepest hole to date, MA20-026A, returned 7.84 g/t Au over 7.0 m (984.0 to 991.0 m with an ETW of 5.60 m) including a higher-grade intercept of 47.8 g/t Au over 1.0 m (985.0 to 986.0m). Four (4) wedge holes were drilled to test the continuity of gold mineralization at these depths at an average hole spacing of 40 m. All four hit mineralization including 8.67 g/t Au over 4.25 m in MA20-026AW1 and 7.01 g/t Au over 3.0 m in MA20-026W5. This mineralization remains open at depth.
Phase Two drilling is nearing completion within the Elbow Zone, with a series of offset holes in progress around MA19-020 (10.59 g/t Au over 4.95 m) establishing a third continuity test zone. This zone is about 650 m deep and lies approximately halfway between the continuity tests noted above around MA19-016 (Figure 3) and MA20-026A (Figure 4), thus giving three sequentially deeper continuity drill tests starting from the bottom of the proposed Magino ultimate pit to a vertical depth of over 1000 m.
Brian Arkell, Vice President Exploration stated: “I’m very encouraged with the grade and continuity from an underground mining standpoint. We’ve drilled a diamond pattern at approximately 30 to 50 metre spacing around MA19-016 from the Phase One program, which returned 14.0 metres at 9.63 g/t Au, and have consistently hit the zone with high-grade mineralization in each of the surrounding holes. Approximately 450 metres below this, our second infill pattern around hole MA20-26 showed similar results with good grade and continuity. We are finalizing a third pattern on the Elbow Zone and have shifted one drill to the Central Zone offsetting Phase One intercept MA19-012, which returned 18.1 metres of 8.31 g/t Au. We are looking forward to receiving and publishing these results, as initial results indicate the Central Zone will demonstrate similar continuity based on what we see visually in the drill core.”
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.
