New Regional Gold-Bearing Structure At The Johnson Tract Project

VANCOUVER - HighGold Mining Inc., President and CEO, Darwin Green, said, “We are seeing encouraging results across the length and breadth of the property and believe that systematic exploration will continue to generate new discoveries at Johnson Tract project in Southcentral Alaska. The geological setting that was permissive in developing exceptional precious metal grades at the JT Deposit appears to extend across the greater property. This thesis is supported by HighGold’s DC discovery hole which ranked #3 on the Opaxe global list of Top 10 Drill Holes of the Year (577.9 g/t Au and 2,023 g/t Ag over 6.4 m in drill hole DC21-010). This is the second time in three years that Johnson Tract has made the Top 10 best drill intersections list, placing #7 in 2019 in the Company’s first drill program and only narrowly missing the list in 2020. With approximately $23M in the treasury, HighGold is well funded to drill these new discovery-stage targets in 2022 while also following up on the highly successful 2021 drill program at Middle DC. We also look forward to completion of an updated mineral resource estimate for the JT Deposit that is due within the next three months and continuing with deposit expansion drilling as part of the greater 2022 exploration program.

HighGold completed geological mapping, geochemical sampling and geophysical surveys in 2021 concurrent with the resource expansion drill program with the objective of assessing the potential for new zones of high-grade mineralization across the district-scale property. The work successfully outlined multiple priority target areas for future drilling related to the prospective 6-km long regional Milkbone Fault system while also advancing the geological knowledge base for the Project. An initial phase of scout drilling at Difficult Creek was also completed, with the balance of remaining results reported herein (10 holes). In addition to the discovery of bonanza-grade mineralization at the Middle DC target area (as previously reported) the drilling provided critical data for vectoring and prioritizing targets as we advance this exciting new target area.

The Milkbone prospect and the +1 km corridor between it and the bonanza-grade drill hole DC21-010 intercept at the Middle DC prospect to the northeast has emerged as a priority target area for the Company with strong supporting surface geochemistry, including soils up to 8.3 g/t Au and rock samples up to 184 g/t Au (representing the highest-grade soil and rock samples within the entire Johnson Tract surface database). The regional Milkbone fault transects this target area and both it and related subsidiary faults appear to have an important control on mineralization and will be drill tested for the first time during the 2022 field season.

The Milkbone fault is also associated with gold mineralization at the Easy Creek prospect, located 6 km north of DC, where a large (1.5 x 2 km) and strong IP chargeability anomaly has been defined that is coincident with anomalous soil geochemistry, rock samples up to 29 g/t Au, large-scale hydrothermal alteration and a circular magnetic anomaly (associated with an intrusive plug). Taken collectively, these multiple layers of supporting data significantly enhance the priority of Easy Creek targets. The Kona prospect, bearing a similar geophysical signature to Easy Creek, is located somewhat lower stratigraphically than DC and the JT Deposit and may represent a portion of the deeper roots of the large-scale Johnson Tract mineralized system.

Geological mapping and rock and soil geochemical sampling focused primarily on underexplored regional prospects including the Milkbone, greater Difficult Creek (“DC”), EC and Kona prospects. The Company also completed 31 line-km of ground-based direct-coupled induced polarization (“DCIP”) geophysical surveys and 267 line-km of detailed airborne drone magnetic (“Drone Mag”) surveys. Encouraging assay results have been returned in both rock and soil sampling across the length and breadth of the Property.

The Milkbone prospect is located 3.2 kilometers northeast of the JT Deposit and is named for the regional Milkbone Fault which strikes north-south for approximately 6 km and lies west of the Middle DC prospect. Mineralization occurs at the surface as epithermal-style quartz-sulphide (± carbonate) extensional and fault-fill veins related to faults and splays and as meter-scale base metal and sulphide-rich quartz-carbonate breccias within faults. In 2020, rock sampling by the Company returned anomalous gold (up to 184 g/t in float) and zinc values (up to 5.2%). Soil sampling returned anomalous gold values (up to 4,390 ppb or 4.39 g/t). A 150m wide gold-in-soil anomaly was defined with values >70 ppb Au.

Rock sampling by the Company in 2021 returned up to 7.85 g/t Au and 599 g/t Ag in quartz vein breccia along with high base metals to 5.0% Cu over 1m (chip sample) and 10.05% Zn, 7.56% Pb and 1.44% Cu (grab sample). Follow-up soil sampling immediately north of the 4.39 g/t Au-in-soil collected in 2020 returned a very encouraging 8.38 g/t Au-in-soil over the trace of the Milkbone Fault.

These results for the Milkbone represent both the highest-grade soil sample (8.38 g/t Au) and the highest-grade rock sample (184 g/t Au) within the entire Johnson Tract surface database. Plans are being designed to test this highly prospective target during the 2022 drill program that will include testing the main Milkbone fault, which is obscured from direct observation due to overburden cover, as well the +1km long corridor that is defined by elevated gold in surface sampling between Milkbone and Middle DC. This drilling will be in addition to systematic follow-up drilling planned at Middle DC.

The Difficult Creek (“DC”) prospect is located four (4) kilometers northeast of the JT Deposit and is characterized by a series of large gossan alteration zones similar in style to the JT Deposit that collectively extend over a 1.5 km x 3.0 km area. Mineralization at DC occurs as base metal- and sulphide-rich quartz-carbonate veins and breccias within pervasively sericite-pyrite ± clay/anhydrite altered, shallowly dipping dacitic volcaniclastic rocks that underly a capping sequence of less altered andesitic volcaniclastic rocks, intruded by quartz-feldspar porphyries. These capping rocks host silver- and gold-rich epithermal-style veins at higher elevations. The widespread extent of mineralization and pervasive alteration exposed along structures and in erosional windows through the andesite supports the potential for a large and partially blind mineralized system linking the various prospects.

Drilling by the Company in 2021 returned exceptional grades of 577.9 g/t Au and 2,023 g/t Ag over a 6.4m width in hole DC21-010 at the Middle DC prospect at shallow depths. The first follow-up drilling of this important new discovery will be a top priority for 2022.

Rock sampling carried out in 2021 by the Company from Middle DC to Upper DC in an area cut by northeast-trending and northwest-trending faults and/or splays related to the Milkbone Fault system returned 3,480 g/t Ag and 0.61 g/t Au (float sample), 1,450 g/t Ag and 7.98 g/t Au over 1m (chip sample), and 11.10 g/t Au and 69 g/t Ag (grab sample); all in epithermal-style quartz veins. Rock sampling of quartz-sulphide veins returned highs of 4.30 g/t Au, 6.1% Zn, 4.4%Pb, 0.5% Cu (grab sample), and 4.53 g/t Au, 38.6 g/t Ag, 18.60% Pb, 4.36% Zn, 1.40% Cu (grab sample).

The Easy Creek (“EC”) prospect is located four (4) kilometers north of the Milkbone prospect along the trace of the Milkbone Fault. Mineralization is characterized by anomalous copper and gold values hosted within sericite-pyrite (± quartz) altered dacitic to rhyolitic volcanic and volcaniclastic rocks intruded by a quartz-diorite plug. Alteration at the EC prospect is extensive and appears to show similarities with the Kona Creek prospect, both of which are associated with strong IP chargeability anomalies that extend over a large area.

In 2019 and 2020, limited rock sampling returned gold values up to 1.3 g/t Au. Soil samples returned anomalous values ranging up to 1.6 g/t Au and up to 0.18% Cu.

Rock sampling by the Company in 2021 discovered a strongly oxidized boulder along the trace of the Milkbone Fault system which returned 29.10 g/t Au. The Drone Mag survey identified a ‘bullseye’ magnetic high associated with the quartz diorite plug, ringed by DCIP chargeability and resistivity anomalies and Au-Cu soil anomalies. This target will be drill tested in 2022.

The Kona prospect is located 2.5 kilometers north of the JT Deposit and is characterized by large (0.5 x 1.0 km) zone of sericite-pyrite (± quartz) alteration that is cored by a large quartz-pyrophyllite alteration zone. Mapped alteration closely correlates with a strong IP chargeability high with a smaller, circular magnetic high on its eastern margin. The chargeability anomaly at Kona was tested with two drill holes during the 2021 program which intersected intense disseminated pyrite and local vuggy silica type alteration (assay results are pending).

Discussion of Upper DC Drill Results

New results are reported for ten (10) scout drill holes (DC21-017 to DC2-026) that tested the Central Fault (3 holes) and Upper DC vein field (7 holes), which represent separate targets located 300 to 1000 meters away from the previously reported high-grade mineralization discovered at the Middle DC target. All holes from the greater Difficult Creek Prospect area have now been reported, with assay results for 13 holes from the JT Deposit area and two holes from the Kona Prospect still pending.

Central Fault drill holes tested below clay-anhydrite alteration at surface that is associated with a topographic lineament. These holes intersected broad intervals (10s of meters) of alteration associated with elevated to anomalous gold values (50 ppb to 600 ppb Au) around a large fault structure (Central Fault). Upper DC drill holes tested beneath Ag-rich epithermal-style veins sampled during the 2020 field season. These drill holes intersected numerous 15 cm to 1.5 m wide epithermal-style veins within andesite volcanics and quartz-feldspar porphyry intrusives; however, were generally unable to replicate the high silver grades obtained from 2020 surface sampling in the area.
