Drilling Commences at Eagle Plains’ 100%-Owned Vulcan Critical

Metals Project, Southeastern BC

Cranbrook, B.C., June 15th , 2023: Eagle Plains Resources Ltd. (TSX -V:EPL) (“EPL” or

“Eagle Plains”) is pleased to report that diamond drilling activity i s underway at the Vulcan

Project, located 30km west of Kimberley, BC . The planned program will include a minimum of

3,000m (9,842’) of diamond drilling in 4-5 holes at the Hilo & West Basin Zones, following up on

encouraging results obtained during 2022 drilling (details following).

Vulcan consists of 12,400ha located 30km west of the world-class Sullivan sedimentary exhalative

(“sedex”) critical metals deposit near Kimberley, BC and is accessible by an extensive network of

well-maintained forest service roads . Encouraging results from the 2022 drill program were

announced previously by Eagle Plains (see news release s December 7th, 2022 and January 18,

2023). Initial observatio ns of core lithologies, mineralogy, alteration and mineral ization from

VU22004 suggest proximity to a sedex-type vent source near the trace of drill-hole VU22004. The

2023 program is designed to extend the mineralized horizons by completing systematic step-out

drilling that will include testing of a prominent off-hole borehole electromagnetic (“BHEM”)

anomaly delineated in late 2022 . Drilling is expected to further define stratabound Pb -Zn-Ag

mineralization and vector towards a suspected source vent complex such as that found at the now-

depleted Sullivan deposit. Eagle Plains management cautions that past results or discoveries on

proximate land are not necessarily indicative of the results that may be achieved on the Vulcan

property.

2022 Drilling Highlights:

• Drillhole VU22004 intersected primary bedded sulphides (sphalerite-galena), as well as

textures, mineral assemblages, garnets and alteration ( tourmalinite, sericite) - all indicative of

proximity to an exhalative (sedex) source

• BHEM outlined a strong conductivity anomaly along strike to the south-southeast of VU22004

at depths consistent with the mineralized interval

• Previously reported analytical results for VU22004 include:

11.55m @ 0.46% Zn, 0.02% Pb, 21.48 ppm Cd, 90.65 ppm Sn (545.50-557.05m), including

• 1.50m @1.72% Zn, 68.83 ppm Cd, 32.09 ppm Sn (554.58-556.08m), including

o 0.22m @ 6.46% Zn, 259.00 ppm Cd, 39.10 ppm Sn (554.58-554.80m), and

o 0.18m @ 3.16% Zn, 126.50 ppm Cd, 26.80 ppm Sn (555.53-555.71m)

Management of Eagle Plains considers the Vulcan project to hold excellent potential for the

presence of sedex zinc/lead/silver mineralization. Rocks underlying Vulcan are within the same

sedimentary sequence and host occurrences, with mineralization and alteration styles similar to

those observed at and adjacent to Sullivan. The Main (Hilo 3) mineral occurrence at Vulcan

returned trench samples up to 1.6 % combined lead-zinc over 1.5 metre s from rocks near the

Lower-Middle Aldridge contact (“LMC”), the same time-stratigraphic horizon associated with the

Sullivan deposit.

Tim Termuende, P.Geo, President and CEO of Eagle Plains commented recently on the Vulcan

program: “We are excited to s ee drilling resume at this important critical metals project. The

target we are testing is world-class in scope and results to date have been extremely encouraging,

suggesting the presence of a mineralized sedex vent system at Vulcan. To date, our geologists have

observed many of the important hallmarks of the nearby Sullivan deposit, giving us confidence that

the upcoming program will provide critical information toward the potential discovery of the

source of mineralization intersected by drilling in late 2022”.

The Sullivan mine was discovered in 1892 and is one of the largest sedex deposits in the world.

Over its 100+ year lifetime, Sullivan contained a total of 160 million tonnes of ore averaging 6.5%

lead, 5.6% zinc and 67 g/t sil ver, resulting in 298 million ounces of silver, 18.5 billion pounds of

lead, 17.5 billion pounds of zinc and significant quantities of associated metals, collectively worth

over $40B at current metal prices.

Vulcan Project History

Sullivan-style mineralization was first reported in the mid-1950s at Vulcan. During the 1970s and

1980s, Texas Gulf Sulphur and later Cominco completed extensive geophysical work and drilled

shallow holes to test for continuous mineralization in areas of the property. Drill testing occurred

in the Hilo area during the early 1990s by Ascot Resources. In 1991 a five -hole, 1003m drill

program was completed, with three holes totaling 1535m completed in 1992.

Since acquiring the initial claims on the property in 2002, Eagle Plains has completed an extensive

compilation of all existing data, followed in 2006 by a 125 line-km helicopter-borne time-domain

geophysical survey flown at 200m spacing. Additional claims were added to the property position

as they became available thro ugh staking. Systematic geochemical, geological and geophysical

programs were conducted by Eagle Plains and its partners from 2011-2019.

In June 2020, Eagle Plains completed a two -hole, 977m drill program to test the LMC along an

existing road cut in an area of elevated soil geochemistry and anomalous geophysical features

(magnetometer, induced polarization and magneto -telluric). The LMC contact was successfully

intercepted in Hole VU20002 with significant alteration suggesting proximity to a hydrothermal

source, though no economic mineralization was encountered.

In 2022, Eagle Plains completed a 537 line -km helicopter -borne high -resolution aeromagnetic

survey. Geophysics was followed -up with a 3 -hole, 1700m diamond drilling program. Hole

VU22004 identified sedex-style mineralization at the West Basin zone deeper in the stratigraphic

package than historically tested. Analytical results from VU22004 defined the best intercept on the

property to date . Results from this program have been used to re -interpret the stratigraphic

sequence at the Hilo and West Basin Zones and have identified target stratigraphy considered to

hold high potential to host economic mineralization.
