HIGHGOLD MINING DETECTS MULTIPLE UNTESTED TARGETS, PART OF A 12KM CORRIDOR AT JOHNSON TRACT PROJECT, ALASKA USA

Highgold Mining Inc. has provided final results from the 2023 airborne geophysical surveys completed at the Johnson Tract polymetallic gold project near tidewater, in south-central Alaska, united States. The project hosts the high-grade JT deposit with an indicated resource of 1.05 million ounces (Moz) at 9.39 grams per tonne (g/t) gold equivalent (AuEq) with average true thickness of 40 metres.

Chief executive officer Darwin Green stated: "This new MobileMT airborne EM and magnetic survey is the first property-wide airborne geophysical survey completed by Highgold at Johnson Tract and is a valuable addition to our exploration toolbox. The survey successfully fingerprints the JT deposit alteration and outlines a 12-kilometre epithermal/VMS trend -- including definition of several new exceptional targets along this corridor. The survey has also detected two significant intrusion-related targets with potential to host Cu-Au [copper-gold] porphyry-style mineralization. We are excited by the results and look forward to testing the targets as we continue unlocking the district-scale potential of the property."

2023 MobileMT airborne geophysical survey highlights:

• The property-wide, 667-line-kilometre airborne EM and magnetic geophysical survey (MobileMT) was conducted on a 100-metre line spacing with resolution from near surface to a depth of two km.
• Three-dimensional inversions and modelling of the MobileMT data successfully fingerprints the alteration halo of the JT deposit and all other known prospects. Significantly, several new high-quality look-alike targets have been identified.
• The MobileMT survey, combined with geology, has delineated a 12-kilometre northeast-trending structurally controlled corridor of epithermal/VMS-style targets that include the JT deposit and Ellis zone and, separate, but likely related, porphyry-style targets at the Easy Creek and Kona prospects.
• Highgold has synthesized these results with previously acquired ground IP geophysics, geological mapping and new geochemical vectoring work to identify and rank high-priority drill targets.

Details of MobileMT airborne and magnetic survey and three-dimensional inversion results

A property-wide, 667-line-kilometre airborne magnetic and EM geophysical survey (MobileMT) was completed by Expert Geophysics Ltd. in August, 2023. Advanced three-dimensional inversion modelling of the data was completed by Geotexera Inc. in December, 2023. The results show apparent resistivity data to a depth of up to two km and effectively highlight known alteration zones and identify several new targets.

Interpretations from the EM and magnetic data combined with current geologic understanding has delineated a northeast-trending corridor of structurally controlled hybrid epithermal/VMS-style mineralization at multiple stratigraphic levels. This corridor includes the Double Glacier, South Valley, Milkbone, Upper DC, East DC and PS prospects and known mineralization at the JT deposit and Ellis zone. These targets all show low- to intermediate-sulphidation epithermal and locally VMS deposit attributes. The EM data have helped to refine drill targets at known prospect areas and identified several new targets within this corridor, most notably the area between the Ellis zone and East DC, and a new target referred to as the Midway target, located 1.5 km northeast of the JT deposit.

The new EM and magnetic data have also improved ranking of the Easy Creek and Kona intrusion-related targets, which demonstrate Cu-Au porphyry potential. Pipe-like magnetic features below or adjacent to significant conductivity and chargeability anomalies are apparent at both Easy Creek and Kona, which show porphyry-style geology, pathfinder elements and alteration at surface. These targets are priority for follow-up surface exploration and drilling.

Epithermal/VMS trend targets

JT deposit-South Valley-Double Glacier trend

The MobileMT EM survey has successfully fingerprinted the alteration zone surrounding the JT deposit as a over-one-kilometre coincident high conductivity (low resistivity) and low magnetic anomalies. Similar anomalies occur long strike to the south, within prospective stratigraphy at the South Valley and Double Glacier targets, suggesting potential for undiscovered JT deposit-style mineralization. Drill testing in 2023 prior to this survey intersected significant alteration at these targets.

DC and Ellis zone anomaly

A large broad conductivity anomaly is identified by the MobileMT EM survey around the Ellis zone. The anomaly supports interpretation of a large, over-two-kilometre hydrothermal system at DC and the likelihood of blind, untested, mineralized targets beneath overburden and cover rocks between the Ellis zone and outcropping quartz-sulphide vein fields at the East DC and Upper DC targets.

Midway -- northeast of JT deposit

A previously unknown, shallow conductivity anomaly occurs within prospective stratigraphy located 1.5 km to the northeast of the JT deposit, roughly mid-distance between the JT deposit and the Ellis zone. This blind target is within 200 m of surface and is covered by younger rocks and vegetation.

Intrusion-related targets

Easy Creek anomaly

The untested Easy Creek prospect shows chargeability and conductivity anomalies and a pipe-like magnetic anomaly, similar to those observed around known Cu-Au porphyry deposits. These geophysical anomalies are centred around a quartz-biotite diorite intrusion mapped at surface. Copper, gold and molybdenum soil anomalies occur over the diorite and to the west near major north-south structures. Magnetite veinlets and miarolitic cavities with chalcopyrite and magnetite mineralization have been mapped and sampled from the diorite and overlying altered tuffs. All of these features are indicative of Cu-Au porphyry deposit prospectivity. Much of the target area is masked by overburden.

Kona anomaly

The Kona prospect shows two strongly sericite-pyrite altered zones. The newly acquired airborne magnetic data has identified a magnetic high between these alteration zones. The westernmost alteration zone appears as a significant chargeability and conductivity anomaly and is cored by clay and quartz-pyrophyllite alteration. The Kona target has the highest tellurium, selenium and bismuth values in soils on the property. All of these features are indicative of Cu-Au porphyry deposit prospectivity.
