Western Alaska Minerals’ New District-Scale CRD-Porphyry Exploration Modeling Reveals High-Potential Targets for 2023 Drilling

TUCSON, ARIZONA, US – February 28, 2023 - Western Alaska Minerals Corp. (the "Company" or "WAM") (TSX-V: WAM) is pleased to announce updated interpretations of geological, geochemical, and geophysical surveys, which combined, indicate multiple high-potential carbonate replacement deposit (“CRD”) and porphyry copper-gold drill targets on the 100%-owned Illinois Creek property in Alaska. 


“East Block” (see Map 1)

  • Geophysics (IP and CSAMT) and soil geochemistry reveal several robust overlapping anomalies that coincide closely with the high-grade silver-lead-zinc CRD mineralization discovered in 2022 (See Press Releases of Sep 22, 2022 and Jan 17, 2023).
  • IP geophysics indicates an offset of the Waterpump Creek CRD mineralization but continuing 1.4 kms to the south across the Illinois fault (See Figure 3 below).  This look-alike anomaly is over three times longer than the current known Waterpump Creek sulfide body. The anomaly continues to the limits of the IP survey.

 “West Block” (see Map 1)

  • Several large-scale new targets have been developed, including an approximately 4 x 2 km target dubbed the “Warm Springs” CRD target. This target is in untested carbonate stratigraphy permissive for mineralization adjacent to historically mined Au/Ag gossans.
  • The Warm Springs CRD target extends to the west into a major coincident copper-gold soil anomaly lying south of the historical Illinois Creek gold oxide mine.  This 1.5 x 1.5 km target could represent the porphyry-related mineralizing fluid source for the property.

“Our rapidly growing data sets have defined some very exciting targets for our upcoming program,” said Kit Marrs, Western Alaska’s President and CEO.  “I would like to acknowledge our technical team for their excellence in compiling and reinterpreting our historical and new data. We are eager to get back on the ground and get the rigs turning”.

Execution Plans

The Company is having additional drilling rigs built for fast-track testing of the numerous targets emerging from the updated exploration model.  Current plans are to drill up to 17,000m in 2023, deploying up to 4 rigs to both expand the Waterpump Creek mineralization discovered in 2022 and begin testing the property wide CRD exploration targets.

A modern 3D IP/resistivity geophysical survey is planned to: 1) Confirm and improve resolution of the reinterpreted Waterpump Creek/Last Hurrah sulfide anomaly; and 2) Define additional anomalies over a 3 x 6 km area of the East Block north and south of the Waterpump Creek discovery. 

A district-wide helicopter-borne geophysical survey to further the understanding of the geologic framework of the East and West Blocks, and to define additional targets including copper-gold porphyry/skarn deposits is also being planned.

Technical Background for 2023 Exploration Program

The regional geologic model has greatly improved over the past few months through integration of historical and new geophysics, geochemistry, and geology from drilling. The updated and improved components for the new exploration targeting model include:

  • An interpretive property-wide geologic map;
  • Further evidence that identified geochemical anomalies show direct correlation with mineralization;
  • CSAMT geophysical survey profiles and lithology from recent and historical drilling provide for a new geologic framework including several faults believed to have controlled CRD mineralizing fluid migration;
  • Reprocessed Induced Polarization (IP)/resistivity geophysical survey results, including 3D inversion modeling and detailed geophysical parameter measurements on drill core; and
  • Modeling of the Waterpump Creek high grade silver-lead-zinc sulfide body.

Importantly, the new geologic interpretation shows the East Block and the West Block, two different lithostratigraphic/structural blocks, separated by “Wade’s” fault.  Each shows distinct geological frameworks and unique exploration targets of significant scope.

The targeting map, Map 1, is derived from historical and 2022 soil geochemistry, drill intercepts, and geophysics briefly described below. For a detailed technical discussion, click here to view our Exploration Update.

Soil Geochemistry

In the East Block, major lead-zinc anomalies occur in dolomites, reflecting leakage from the Waterpump Creek feeder structure.  A major soil anomaly at the Last Hurrah target continues for another 2 kilometers and may reflect the presence of the Waterpump feeder fault downdip.

In the West Block, major lead and zinc anomalies reflect where the mineralized permissive carbonate stratigraphy comes to surface between the Illinois Creek fault and the Warm Springs fault.  These anomalies reflect the Illinois Creek oxide gold-silver deposit.  South of the Illinois Creek pit and the Warm Springs fault, an extensive (1.5 x 1.5 km) newly recognized copper, gold, lead, zinc soil anomaly continues to the south along an apparent NNW to NNE-trend.  This anomaly with its copper and gold signature could suggest leakage from a possible porphyry center at depth.

Waterpump Creek Sulfide Body

In Figure 2, drill intercepts from 2021-2022 define the 3D shape (yellow) of the Waterpump Creek sulfide body.  Red circles show 2023 target areas to be drilled to extend known sulfide mineralization.  The historical oxide body outline is shown to the north. 


The 2005 IP/Resistivity geophysical data were reprocessed and reinterpreted by the Company’s recently hired geophysicist contractor, Brock Bolin, with key results shown in Figure 3 below. The 3D inversion modeling shows that a strong conductivity anomaly coincides closely with the Waterpump Creek sulfide body. The anomaly continues to the Illinois Creek fault, where it is offset to the west. From there it is continuous and increases in apparent volume for over 1.4 km to the southern limit of the survey. The highly prospective Last Hurrah target (Map 1) is based on a combination of the geometry of the known CRD mineralization (Fig. 2), coincident soil geochemistry anomalies (Fig. 1), and the conductivity anomaly results shown in Figure 3.
