WESTERN ALASKA MINERALS REPORTS ASSAYS FOR MULTI-STAGE CRD FEEDER ZONE CUT IN

TUCSON, ARIZONA, US – September 22, 2022 - Western Alaska Minerals (the "Company" or
"WAM") (TSXV: WAM) is pleased to announce geological observations and assay results fr om
massive sulfide mineralization cut at its Waterpump Creek Carbonate Replacement Deposit
(“CRD”) on its 100% owned Illinois Creek Project in western Alaska. The results incorporate
visual data from drillholes WPC22-21 and 22 and assay data for WPC22-17 and 18 (See Table 1
and News Releases of July 5th and 20th, 2022). Visual data for Holes 21 and 22 are reported
here for the first time. Assays for both, as well as WPC22-20, are pending.
The intercepts in all holes show multi ple stages of sulfide mineralization characterized by
alternating zinc -dominant sphalerite -rich and lead-silver dominant galena -rich sulfide
mineralization zones. Sulfides thicken progressively towards drillholes WPC22-17 and 18 (48.8
and 101.7 meters respectively) both of which include significant zones of late-stage pyrite
showing multiple stages of brecciation and mineralization.
The 102 meter intercept in drillhole WPC22-18 is by far the thickest and most mineralogically
complex hole to -date with three intervals of high-grade Pb-Ag rich Ag-Pb-Zn mineralization .
Additional intervals of Zn-dominant mineralization and lower-grade, late, multi-stage pyrite are
also present . The combination of the abrupt thickening of mineralization towards drillhole
WPC22-18 and its multi-stage complexity strongly indicate it is an important CRD feeder zone.
Notably, WPC22-18 appears to lie at the intersection of the N -S Waterpump Creek graben and
NE-SW Illinois Creek Fault, which suggests similar intersections identified elsewhere on the
property may also host feeders that guided mineralizing fluids into the favorable carbonate host
rocks.
“Following progressively thicker and more complex mineralization encountered in WPC22-17 and
18 and then seeing it thin again as we drilled further southward along the WPC graben strongly
suggests we hit a feeder chimney located at the intersection with the Illinois Creek Fault,” said
Joe Piekenbrock, Chief Exploration Officer. “Combining this with the extensive historical mining
five kilometers to the southwest along t he I llinois Creek Fault strongly reinforces our
interpretation that it is one of the major mineralization controls in the district and increases the
importance of drilling along it, especially where it intersects other similar structures now seen in
the CSAMT survey.”
“It is remarkable to have cut a sulfide feeder zone so early in a CRD exploration program and this
opens up a number of very exciting targets along the Illinois Creek Fault,” said Dr. Peter Megaw,
exploration advisor to WAM. “ Having WPC22-18 to ground -truth geologic models and
geophysical interpretations should greatly facilitate efficient exploration throughout this
apparently very large scale CRD system”.

Waterpump Creek Drilling: Analysis To-Date
The manto mineralization encountered to date forms an elongate body 30 to 75 meters wide
and 400 meters in length plunging gently to the south in the footwall dolomite adjacent to the
WPC Creek structure. The overall architecture defined in the 2022 CSAMT profiles, indicates this
structure is the western margin of a graben-like depression 500 to 600 meters wide that down-
drops and drapes the overlying chlorite and graphite schist package onto the underlying
dolomite section. As discussed earlier, there is an apparent chimney at the intersection of the
WPC manto and the projection of the Illinois Creek Fault.
To better understand the trend and lateral continuity of the WPC manto, a profile of four drill
holes spaced from 25 to 40 meters has been completed on Section 7104900, 50 meters south
of the exceptional ly thick interval encountered in WPC22 -18. Figure 1 shows this EW cross -
section (7104900N) which lies 250 meters south of the previously reported 7105150N section
through mineralization in WPC22-07 (See News Release of August 2, 2022).
WPC22-20, 21 and 22 all cut significant massive sulfide intervals. From west to east the section
shows: WPC22-21 cut 4.0 meters ; WPC22-22 cut three intervals totaling 67.3 meters; and
WPC22-20 cut two intervals totaling 32.1 meters of mineralization.
Mineralization in section 7104900 again shows mineralization replacing the dolomite along the
fold hinge of the dolomite as it is draped and/or faulted into the Waterpump Creek graben.
Alteration forms a halo around the massive mineralization often as bleached dolomite along
with quartz, dolomite, and calcite veins. Fluorescent fugitive calcite veins are concentrated
peripherally at or near the top side of the massive mineralization and form a local vector of up
to 50-100 meters around the massive sulfide.
Figure 1. Cross-section (7104900N) (W-E)
Ongoing drilling has now moved 200 meters to the south to section 7104700 due to a wide
expanse of wetlands that preclude drilling in 2022 . Late spring drilling and specialized
equipment will be needed to drill this gap in 2023.
Figure 2 is an updated longitudinal section along the axis of 2022 Waterpump Creek drilling. The
mineralized body plunges to the south at 15-20 degrees along the western margin of the
Waterpump Creek graben. Mineralization thickens dramatically south of 7105050N and shows
the apparent chimney developing at the intersection of the WPC manto and the projection of
Illinois Creek Fault. Future resource drilling should further define the geometries of the
mineralized body.

Figure 3 is a pierce point plan map of 2022 drilling at Waterpump Creek. The plan map shows
the apparent intersection of the WPC manto and the projected trend of the Illinois Creek Fault.
Importantly, Figures 3 shows th e continuation of strong manto mineralization to the south of
the likely WPC22-18 chimney at the intersection of the WPC Fault-controlled manto and the
projection of the Illinois Creek syn-mineral fault.

CRD Discussion
To better understand the implication of WAM’s ongoing CRD exploration at Waterpump Creek
and the greater Illinois Creek District, a brief discussion on CRD’s geometries, zoning and scale
is available on our website and as an Appendix to this news release.
CSAMT Geophysical Program
In addition to the ongoing two rig drill program, a major system-wide CSAMT (controlled-source
audio-magnetotellurics) geophysical program was completed in June covering the +/- 8 km
distance between the Illinois Creek oxide mineralization, the Last Hurrah area and the
Waterpump Creek target area. Inversion modeling of the CSAMT sections is ongoing.
Preliminary results show a complex interplay of stacked thrusts and high -angle syn -mineral
faults. The Waterpump Creek structure, the major mineralization control for the WPC manto, is
apparent as the west bounding fault of the WPC graben which extends over at least 6 km of
strike within the CSAMT sections south from Waterpump Creek through Last Hurrah to just east
of the major East IC manto/gossan. Importantly, the survey shows the scale of the Illinois Creek
CRD system is on par with some of the largest and richest CRD systems in the world , including
the Santa Eulalia deposit in Mexico and the Tintic deposit in Utah (see the attached Appendix).
A preliminary geologic re-interpretation and specific target zones are shown in Figure 4 based
on the CSAMT inversions . Three apparent NNE -trending extensional faults are evident in the
inversions: The west and east bounding fau lts defining the Waterpump Cr eek graben; and
Wade’s Fault trend which shows major down-drop to the west preserving the entire 400-meter-
thick prospective carbonate stratigraphy recognized in the District. The graben-like down-drop
to the west of Wade ’s Fault suggests that the dolomite between the Waterpump Creek Fault
and Wade ’s Fault is a horst block of prospective carbonate stratigraphy with only the lower
dolomite section preserved.
The permissive stratigraphic section is characterized by an upper 100-meter thick, calcareous
sandstone underlain by a 100-meter dolomitic sandstone and in turn, underlain by a 200-meter
dolomite section. This permissive section lies immediately below the greenstone sill and a thin
20 to 50-meter thick graphitic schist. Late high-angle NE-trending faults, the Illinois Creek Fault
and the Warm Springs Fault crosscut this framework.
Deep oxidation is apparent between the Illinois Creek and Warm Springs Faults as is
demonstrated at the Illinois Creek oxide Au/Ag deposit and the East Illinois Creek manto . The
Illinois Creek oxide Au/Ag deposit formed as replacement mineralization in the Illinois Creek
Fault and the East Illinois Creek manto formed in the hanging-wall of the Illinois Creek Fault as
a replacement body at the contact between calcareous and dolomitic quartzites roughly 100
meters below the greenstone sill.
Importantly, a major conductive anomaly is apparent in the data lying below: a shallow dipping
Jurassic greenstone sill empl aced at the top of the prospective stratigraphy; and south of the
Warm Springs Fault. This fault block was not tested in any of the historical drilling and suggests
a major potential new target 4 x 2 kilometers in scale.
Two initial drill holes tests have been completed in August and September through the
greenstone immediately west of Wade ’s Fault testing this highly p rospective untested block
south of the Warm Spring s Fault. Drillhole IC22-01 has intersected 50+ meters of intense
silicification, brecciation and massive pyrite mineralization with anomalous XRF base metal
values below the greenstone sill. The hole was terminated due to poor drillhole conditions and
a second hole IC22-02 roughly 500 meters to the northwest and closer to the Warm Springs
Fault again intersected major silicification and brecciation with lesser but still significant pyrite
component, again below the greenstone sill. The hole was lost due to intense sanding of the
calcareous quartzite . A third hole testing west across Wade ’s Fault into this stratig raphy is
ongoing. Importantly, this drilling roughly 3 kilometers south of the ongoing Waterpump creek
drilling shows that mineralizing fluids of the Illinois Creek CRD system lie below the extensive
greenstone sill and significantly expands the potential target area for replacement
mineralization.

Kit Marrs, Western Alaska Minerals CEO, stated “Our 2022 drilling program at Waterpump Creek
has now outlined a 400 meter long trend of high grade silver-lead-zinc mineralization. This is a
significant step towards defining an economic CRD deposit. Mineralization has thickened and
become wider as the drilling has moved south along trend. Our 2022 drilling success, along with
the results of the June CSAMT geophysical survey has demonstrated that we have a major CRD
system with excellent potential for additional discovery. The two exploration holes, IC22-01 and
IC22-02, completed to date on targets outlined by the CSAMT survey, demonstrate that we are
just now understanding the potential of this CRD system.”

Quality Assurance/Quality Control
Quality Assurance/Quality Control of drill sample assay results are independently monitored
through a quality assurance/quality control (“QA/QC”) protocol which includes the insertion of
blind standard reference materials, blanks, and duplicates at regular intervals.
All logging and sampling procedures are completed at WAM’s core handling facilities located at
the Illinois Creek mine camp in Alaska. Drill core is logged under an established procedure using
Geospark commercial logging software, then diamond sawn on site. Half drill-core samples are
then securely transported to ALS facilities in Fairbanks, Alaska from Illinois Creek under a strict
chain of custody protocol. Sample pulps are then sent to ALS’s lab in Vancouver, Canada, f or
analysis. Gold content is determined by fire assay of a 30 -gram charge with ICP finish. Silver ,
lead, copper, and zinc along with other elements are analyzed by ICP methods utilizing a four-
acid digestion. Over-limit samples for silver, lead, copper, and zinc are determined by ore-grade
titration analyses. ALS Inc. is independent of Western Alaska Minerals and its affiliates.
ALS also performs its own internal QA/QC procedures to assure the accuracy and integrity of
results. Parameters for ALS’ internal and WAM’ external blind quality control samples are
acceptable for the elements analyzed. WAM is unaware of any drilling, sampling, recovery, or
other factors that could materially affect the accuracy or reliability of the data referred to
herein.
About WAM
WAM began trading on the TSX -V in November 2021 and maintains corporate offices in Alaska
and Arizona. WAM fully controls all claims in the historic Illinois Creek Mining District located in
western Alaska near the Yukon River, covering 73,120 acres ( 114.25 square miles or 2 9,591
hectares). The District was originally discovered by Anaconda Minerals Co. in the early 1980's.
Since 2010, WAM and its private precursor company Western Alaska Copper & Gold Inc. has
reassembled the Anaconda property package and been engaged in exploring the District. The
District encompasses at least five deposits containing gold, silver, copper, lead, and zinc.
The Company currently has approximately 22,414,104 common shares issued and outstanding
and 238,643 proportional shares issued and outstanding. Each proportional share is convertible
to 100 common shares at the request of the shareholder and in the discretion of the Company.
Because of these conversion rights, for market capitalization and financial analysis purposes, it is
appropriate to convert the proportional shares to common shares and add the product of the
conversion to the current number of common shares outstanding. When doing so, the sum of
the approximate number of common shares ( 22,414,104) and converted proportional shares
(23,864,300) equals 46,278,404 shares. Further information regarding the Company’s share
structure is available upon request.
