Eagle Plains Partner Earthwise Intercepts Mineralization in all Holes at the Iron
Range Precious Metals Project, BC.
Cranbrook, B.C ., June 16, 2026: Eagle Plains Resources Ltd. (TSX-V:EPL) (OTCQB: EG PLF) (“EPL” or “ Eagle
Plains”) is pleased to announce that partner Earthwise Minerals Corp. ( CSE: WISE FSE: 966; OTCQB: EWISF)
(“Earthwise” or “WISE”) has completed the diamond drilling program at Eagle Plains’ 100% owned Iron Range
Project, SE British Columbia. Earthwise holds the exclusive option to acquire up to a n 80% interest in the Iron
Range Project.
The 20,021 ha Iron Range Project is considered by management of both Eagle Plains and Earthwise to hold
excellent potential for the presence of structurally controlled gold-silver mineralization, iron-oxide copper-gold
(“IOCG”) and Sullivan -style lead -zinc-silver sed imentary-exhalative (“sedex”) mineralization. The property is
owned 100% by Eagle Plains, with part of the property subject to an underlying 1.0% Net Smelter Royalty held
by a third party. The drill program was managed by Terralogic Exploration Inc. and diamond drilling was
contracted to QB Drilling.
The 2026 drill program was designed to infill historical mineralized intercepts and assess continuity of
mineralization along trend at the Talon Zone structure, where 2010 drilling by Eagle Plains intersected 2 intervals
of strong and continuous mineralization including 14.0m grading 5.1g/t gold, 1.86% lead, 2.1% Zinc, 75.3g/t
silver and 7.1m grading 8.13g/t gold, 2.84% lead, 3.07% zinc, 86.6g/t silver (DDH IR10010).

DDH IR26053 was designed to cross-cut the Talon Zone structure, infilling historical holes IR11011 and IR11015
(125m spacing at target depth). The hole was collared in the middle Aldridge Formation, intercepting the
regionally significant lower-middle Aldridge Formation Contact (LMC) at approximately 120m depth. The Talon
Zone structure, intercepted between 280-396m, is defined by strong silica-feldspar alteration associated with
dense, chaotic quartz-feldspar-ankerite veins. Polymetallic mineralization (pyrrhotite-pyrite-sphalerite-galena-
arsenopyrite-sulfosalts) was noted throughout the structural zone within veins, as fracture infill and forming
localized breccia cement.
DDH IR26054 was designed to cross-cut the Talon Zone structure, infilling between historical holes IR10010
and IR11011 (60m drill spacing at target depth). The hole was collared in Middle Aldridge stratigraphy,
intersecting the LMC at approximately 53m. The Talon Zone Structure, intercepted between 258-345m, is
defined by strong silica-feldspar alteration associated with chaotic quartz-feldspar-ankerite veins. Polymetallic
mineralization (pyrrhotite-pyrite-sphalerite-galena-arsenopyrite-sulfosalts) was noted throughout the
structural zone as veins, fracture infill and localized breccia cement.
DDH IR26055 was designed to overcut IR11015, assessing continuity of the mineralized structural trend to the
southwest, an area that is historically underexplored. The hole successfully intercepted an upper and lower
mineralized horizon first defined in DDH IR11015. The hole was collared in the upper mineralized horizon (15-
80m), where polymetallic mineralization (pyrrhotite-pyrite-sphalerite-galena-arsenopyrite-sulfosalts) is
associated with intense oxidization of sulphides and strong silica and feldspar alteration of the Middle Aldridge
sediments. The main (lower) Talon Zone mineralized horizon was intercepted between 241-380m, a 40m step-
out from IR11015. The zone is defined by moderate silica alteration of Lower Aldridge sediments associated
with dense, chaotic quartz-feldspar-ankerite veining. Polymetallic mineralization (pyrrhotite-pyrite-sphalerite-
galena-arsenopyrite-sulfosalts) is dominantly hosted within the veins and as fracture infill.
Samples have been submitted to ALS Global (North Vancouver) for Fire Assay (Au) and full multi-element
characterization.
Chuck Downie, President and CEO of Eagle Plains commented “We are excited to return to exploration drilling
at the Iron Range . The known, structurally controlled, Talon Zone mineralization correlates with multi element
geochemical anomalies and strong IP resistivity and chargeability signatures, with similar features in the area
remaining untested by drilling.”

Iron Range Project Summary
The 20,021ha Iron Range Project located near Creston, BC, is owned 100% by Eagle Plains, subject to a 1% NSR
held by a third party on a portion of the claim group. A well -developed transportation and power corridor
transects the southern part of the proper ty, including a high -pressure gas pipeline and a high -voltage hydro-
electric line, both of which follow the CPR mainline and Highway 3. The rail line provides efficient access to the
Teck smelter in Trail, B.C. The project is fully permitted with a Multi-Year Area Based (MYAB) permit in place
issued by the BC Ministry of Mining and Critical Minerals that includes provisions for geophysical work,
mechanical trenching, access trail construction and diamond drilling.
The Iron Range property covers an extensive area approximately 10km x 32km which overlies the regional Iron
Range Fault System (“IRFS”). Prior to the acquisition by Eagle Plains in 2001, the property had seen little
systematic exploration for other than iron resources known to exist on the property since the late 1800s. Since
2001, Eagle Plains and its partners have completed 21,593m of diamond-drilling in 87 holes, collected 2482 line-
km of airborne and surface geophysical data and analysed 10,053 soil geochemical samples, 495 rock samples
and 6955 drill core samples.
Drilling at Iron Range in 2010 resulted in the discovery of the Talon Zone, where drill-hole IR10-010 intersected
2 intervals of strong and continuous mineralization including 14.0m grading 5.1g/t gold, 1.86% lead, 2.1% Zinc,
75.3g/t silver and 7.1m grading 8.13g/t gold, 2.84% lead, 3.07% zinc, 86.6g/t silver (Eagle Plains news release
December 21st, 2010). Previous drilling 10km north of the Talon Zone in 2008 by Eagle Plains intersected gold
mineralization in drill-hole IR08006 which assayed 7.0m grading 51.52g/t (1.50 oz/ton) gold (Eagle Plains news
release dated April 20th, 2009).
Mineralization at the Pyromorphite Zone (BC MinFile 082FSE141) was discovered in 2009 after construction of
logging roads exposed sheared and brecciated sediments hosting cm -scale quartz veins bearing pyromorphite
(lead) mineralization. No significant work has been completed at the zone since its initial discovery by the
previous tenure holder. Rock (grab) sample SK10 -207 reports 27.0 g/t Au, 173.0 g/t Ag, and 13.4% Pb (BC
Assessment Report 31659). Rock (grab) sample MK10 -170 reports 54.7 g/t Au, 42.2 g/t A g, and 2.8% Pb (BC
Assessment Report 31659). 2025 fieldwork at the Pyromorphite returned up to 13.4 g/t Au, 27.2 g/t Ag, > 10,000
ppm As, and 2.7% Pb from an in-situ grab sample. (KBBIRR004) (Eagle Plains news release dated November 17,
2025). The poly-metallic (As-Pb-Zn) nature of the mineralization at the Pyromorphite Zone and the association
between arsenopyrite (As) and Au mineralization are consistent with the structurally hosted mineralization that
defines the Talon Zone target 12 km to the SW.
Rock grab samples are selective samples by nature and as such are not necessarily representative of the
mineralization hosted across the property. Some of the above results were taken directly from MINFILE
descriptions and assessment reports (ARIS) filed with the BC government. Management cautions that historical
results were collected and reported by past operators and have not been verified nor confirmed by a Qualified
Person but form a basis for ongoing work on the subject properties. Management cautions that past results or
discoveries on proximate land are not necessarily indicative of the results that may be achieved on the subject
properties.
