HighGold Step-outs Expand New Argus Zone 300 meters Along Strike at Munro-Croesus Gold Project, Timmins Ontario

HighGold Mining Inc. (TSX-V:HIGH, OTCQX:HGGOF) ("HighGold" or the "Company") is pleased to report further assay results from the 2022 Winter Drill Program (the "Program") at its Munro-Croesus project ("Munro-Croesus" or the "Project") located in the Timmins Gold Camp, Ontario, Canada (Figure 1). The Company completed an additional five (5) drill holes on the new Argus Zone ("Argus") on the western side of the Project, 3 kilometers from the historic Croesus Mine, and continued to successfully intersect wide intervals of gold mineralization. These results reinforce the potential for bulk-tonnage style gold associated with the Pipestone Fault at Munro-Croesus.

The Argus Zone represents a very early-stage new discovery within the East Timmins area, a region that is host to over 15moz of undeveloped resources. The Argus Zone has now been defined over a strike length of 300 meters and a depth of 250 meters and remains open in all directions.

New Highlight Drill Hole Results from the new Argus Zone

Drill Hole MC22-111

• 52.3 meters at 0.48 g/t Au, including
  • 10.5 meters at 0.87 g/t Au, and
  • 9.8 meters at 1.09 g/t Au

Drill Hole MC22-112

• 68.0 meters at 0.40 g/t Au, including
  • 10.0 meters at 1.23 g/t Au

Drill Hole MC22-114

• 27.0 meters at 0.61 g/t Au, and

See Table 1 for additional assay details and Figures 1, 2 and 3 for location maps and cross sections.

"With our first step-out drilling at the new Argus Zone, we are seeing the emergence of a new and potentially significant bulk-tonnage gold system," commented President and CEO Darwin Green. "Broad widths of encouraging gold mineralization have been intersected in six out of seven holes with excellent promise for further expansion. The surrounding area is completely untested with no prior drilling and our next steps at this discovery will be exploring the extents of the gold system, including tracking it west toward the intersection of the Argus Zone trend with the regional Pipestone Fault."

Discussion of Results for the New Argus Zone

The first two drill holes reported by the Company at the new Argus Zone intersected wide zones of near-surface bulk-tonnage style gold mineralization highlighted by 62.8 meters at 0.79 g/t within 136.0 meters at 0.54 g/t Au in MC22-110 (see Company press release issued dated May 9, 2022).

Drill holes MC22-111/112/113/114/115 reported today tested the down-dip and strike extent of the new Argus Zone over a 400 meter by 400 meter area and returned encouraging values in four of five holes, including 52.3 meters at 0.48 g/t Au in hole MC22-111, 68.0 meters at 0.40 g/t Au in hole MC22-112, and 27.0 meters at 0.61 g/t Au, 48.6 meters at 0.62 g/t Au and 18.6 meters at 0.32 g/t Au (collectively 94.2 meters) in hole MC22-114. Hole MC22-113 was drilled 100 meters to the northeast across a north-south trending fault and is interpreted to have missed the faulted projection of the zone. Hole MC22-115 was drilled north through the Pipestone Fault into the southwest trend of the Argus Zone and intersected 6.5 meters at 0.62 g/t Au within a silicified zone with the Pipestone Fault and then 44.0 meters of 0.25 g/t Au, including 1.0 meters at 3.56 g/t Au lower in the hole.

Drill hole locations for the five (5) holes reported herein are shown in Figures 2 and 3 with Significant Assay Results summarized in Table 1. An aerial image of the drill rig from the winter program at the Argus Zone is presented in Photo 1.

The Munro-Croesus Project

The Munro-Croesus Project is located along Highway 101 in the heart of the Abitibi greenstone belt, Canada's premier gold mining jurisdiction (Figure 1). Extensive land consolidation by the Company in 2020-2021 unified the patchwork of patented and unpatented mining claims surrounding the Croesus Gold Mine and enhanced the exploration potential of the Project. The Project covers 51 km² (20 mi²) of highly prospective geology within the influence of major gold-bearing structural breaks, including control of approximately 8 kilometers strike length of the regional Pipestone Fault - an attractive setting for gold mineralization within the Timmins and Golden Highway Gold Camps. Multi-million-ounce bulk-tonnage (<1 g/t) gold deposits located in the immediate region include the Tower Gold Project being developed by Moneta Gold Inc. and the Fenn-Gib Gold Project being developed by Mayfair Gold Corp. The Black Fox underground gold mine operated by McEwen Mining is located 1.5 km southwest of the Munro Croesus property.

The new Argus Zone is located 3 kilometers west-northwest of the past-producing Croesus Mine (Figure 2). It is a broad zone of surface gold mineralization within the influence of the regional gold-bearing Pipestone Fault. The Argus Zone is characterized by silicified mafic variolitic volcanics cut by northeast-trending pyritic veinlets within a broader halo of carbonate alteration and local development of specular hematite. Selective historical sampling during a small 1990s-era drill program yielded promising gold assays over narrow widths with large sections of core unsampled. HighGold's recognition that mineralization may be more widespread provided the rationale to target the prospect, resulting in the discovery of bulk-tonnage style gold.

2022 Winter Drill Program

The 2022 Winter Drill Program was completed in early April with a total of 7,401 meters drilled in 33 holes. Assay results have now been reported for 14 drill holes with results for 19 drill holes currently pending.

Additional Notes: Starting azimuth, dip and final length (Azimuth/-Dip/Length) for drill holes reported today are noted as follows: MC22-111 (315/45/276m), MC22-112 (315/45/267m), MC22-113 (315/45/276m), MC22-114 (315/45/384m), and MC22-115 (360/45/300m).

Samples of drill core were cut by a diamond blade rock saw, with half of the cut core placed in individual sealed polyurethane bags and half placed back in the original core box for permanent storage. Sample lengths typically vary from a minimum 0.2-meter interval to a maximum 1.5-meter interval, with an average 0.5 to 1.0-meter sample length. Drill core samples were delivered by truck in sealed woven plastic bags to ALS Geochemistry laboratory facility in Timmins, Ontario for sample preparation with final analysis at ALS Geochemistry Analytical Lab facility in North Vancouver, BC. ALS Geochemistry operate meeting all requirements of International Standards ISO/IEC 17025:2017 and ISO 9001:2015.

Gold is determined by fire-assay fusion of a 50 g sub-sample with atomic absorption spectroscopy (AAS). Samples that return values >10 ppm gold from fire assay and AAS are determined by using fire assay and a gravimetric finish. Various metals including silver, gold, copper, lead and zinc are analyzed by inductively-coupled plasma (ICP) atomic emission spectroscopy, following multi-acid digestion. The elements copper, lead and zinc are determined by ore grade assay for samples that returned values >10,000 ppm by ICP analysis. Silver is determined by ore grade assay for samples that returned >100 ppm.

The Company has a robust QAQC program that includes the insertion of blanks, standards and duplicates.

Readers are cautioned that the Company has no interest in or right to acquire any interest in any of the neighboring mines or deposits, and that mineral deposits, and the results of any mining thereof, on adjacent or similar properties are not indicative of mineral deposits on the Company's properties or any potential exploitation thereof.
