3.40 g/t Gold over 0.5 meters in Croesus Vein Extension & 14.00 g/t Gold over 0.6 meters in New Parallel Vein

HighGold Mining Inc. (TSX-V:HIGH) (OTCQX:HGGOF)  is pleased to report assay results for the first seven holes from the 2022 Winter Drill Program at its Munro-Croesus project located in the Timmins Gold Camp, Ontario, Canada (Figure 1). The planned 8,000-meter Program is the largest to date on the Project and continues to test targets proximal and distal to the past producing Croesus Mine, along with a variety of new targets on the greater consolidated land position.

New drilling has successfully intersected the equivalent of the historic high-grade Croesus Vein in hole MC22-96, positioned 100 meters to the northeast of the former Croesus Mine underground workings, and has also discovered a new parallel quartz vein, 370 meters to the northwest, in the prospective Croesus Flow. Assay highlights are discussed below and shown in Figure 2 and Table 1.

Highlight Drill Hole Results

• 13.40 g/t Au over 0.5m within a broader 4.80m interval grading 3.60 g/t Au (hole MC22-96) from an intersection of the Croesus Vein 100m northeast of the Croesus Mine
• 14.00 g/t Au over 0.6m within a broader 2.60m interval grading 3.42 g/t Au (hole MC22-92) from a new vein zone intersected 370m northwest of the Croesus Mine

“We are very encouraged by these new results, which have intersected the interpreted northeastern extension of the historic high-grade Croesus Vein and have also identified a prospective parallel quartz vein system to the northwest,” commented President and CEO Darwin Green. “These discoveries are a ‘proof of concept breakthrough’ of our current geological and structural models which highlight the potential for the Croesus Vein system to continue to the northeast along a major regional structure and also, as demonstrated in hole 92, that the prospective Croesus Flow could host multiple analogues to the Croesus Vein as we target this favourable host along strike. Step One was successful confirmation that key gold-bearing vein structures extend outside the immediate area of the historic Croesus Mine. Step Two will be systematic follow-up drilling, expanding the extent of these new intersections, and testing for the type of exceptionally high-grade gold mineralization that the Croesus Mine was known for.”

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). The Project covers 51 km² (20 mi²) of highly prospective geology situated between the Black Fox Mine Complex operated by McEwen Mining Inc. and the Fenn-Gib gold deposit being developed by Mayfair Gold Corp. and lies proximal to major gold-bearing breaks. Extensive land consolidation by the Company in 2020-2021 has now unified the patchwork of patented and unpatented mining claims surrounding the Croesus Gold Mine into one coherent package and has enhanced the exploration potential of the Project.

The former Croesus Gold Mine is renowned for having produced some of the highest-grade gold mined in Ontario. Total historical Croesus mine gold production from milled ore as reported by the Ontario Department of Mines (Reference- ODM Vol. LX, Part VIII, 1951) was 14,854 ounces gold from 5,333 short tons milled for an average grade of 2.78 oz gold per short ton (95.3 g/tonne). Research by a previous owner suggests that the above-reported milled ore production did not include the very high-grade direct shipping gold ore which was shipped directly to the Canadian Mint for processing. Five (5) gold samples purchased by the Ontario Bureau of Mines for exhibition purposes and now in possession of the Royal Ontario Museum in Toronto, Ontario weigh 85 pounds collectively and contain 480.7 ounces of gold or 11,310 oz gold per short ton (387,727 g/tonne).

Discussion of Results

Croesus Vein Northeast Extension and Down-Dip Targets

A portion of the 2022 Winter Drill program was designed to test for the possible strike extension of the historic Croesus Vein to the northeast of the underground workings in an area of no previous drilling. Recent structural geology studies completed by SRK Consulting identified a dominant NE-SW trending “D2” structure passing through the Croesus Shaft area and highlighted the importance of these D2 structures as potential hosts for gold mineralization, with particular attention given to areas where these structures cross-cut mafic variolitic flows and graphitic interflow sedimentary rocks. Three (3) holes (MC22-94 to MC22-96) were designed to test this D2 feature north of the mine, with a fourth hole (MC22-97) testing at depth below the historic mine workings.

Hole MC22-96, located approximately 100 meters from the Croesus mined-out stopes and drilled at -65 degree dip, yielded 3.60 g/t Au over 4.80 meters, including 13.40 g/t Au over 0.5 meters. The mineralization in hole MC22-96 is characterized by 20-30% quartz veining with 2-5% arsenopyrite within a quartz-sericite-pyrite altered basalt. Narrow pyrite-pyrrhotite-bearing graphitic interflow sediments were observed downhole of the gold intercept and returned encouraging base metal values with 2.89% Zn, 1.03% Pb and 13.09 g/t Ag over 2.1 meters. Both these intercepts remain open at depth and along strike to the northeast.

Hole MC22-95, drilled at a shallower -45-degree dip from the same pad as hole MC22-96, intersected the same structure but returned only anomalous gold values (1.28 g/t Au over 1.16 meters).

Hole MC22-94, drilled immediately northeast of the underground workings (100m southwest of holes 96 and 96) returned no significant values, with faulting inferred to have offset the Croesus Vein.

Hole MC22-97 was a deeper test below the underground workings and returned only anomalous gold values (1.16 g/t Au over 0.50 meters and 1.70 g/t Au over 0.60 meters).

Northwest Croesus Flow Target

The historic Croesus Vein is developed within the upper sulphidic pillow breccia phase of the Croesus Flow (basalt). The Company has targeted this prospective Croesus Flow along strike to the southeast and northwest of the Croesus Mine to identify areas where this flow is cross-cut for by modeled D2 structures and thus has the potential for a repetition of ‘Croesus-style’ veining and mineralization.

Hole MC22-92 returned 3.42 g/t Au over 2.60 meters, including 14.0 g/t Au over 0.6 meters within veined and quartz-sericite-pyrite-altered pillowed Croesus Flow. This intersection is located approximately 370 meters northwest of the Croesus shaft and may represent a new northern extension of the historic Brown-Munro vein, located 365 meters to the southwest. The inclined #1 Shaft was sunk at the northern end of the Brown-Munro vein circa 1908 to a depth of 318 feet and the Brown-Munro vein reportedly contained visible gold where intersected by drilling at the 300 foot level (Reference – The Northern Miner, August 14, 1918).

Holes MC22-91 and MC22-93 were drilled to the west of the Croesus shaft and returned only anomalous values (1.29 g/t Au over 0.50 meters and 0.62 g/t Au over 1.0 meters in hole MC22-93).

Drill hole locations for the seven (7) holes reported herein are shown in Figure 2 with Significant Assay Results summarized in Table 1.

Current 2022 Winter Drill Program

The 2022 Winter Drill Program is in progress and is a continuation of the late 2021 Fall Drill Program. The 8,000-meter Winter Program includes one drill rig and is expected to run until mid-April. The Program will test established targets near the past-producing Croesus Gold Mine, as well as, first-pass drilling at several new priority targets generated on the greater Project.
