Eagle Plains Provides Update on Lost Horse Copper-Gold Project /

Announces Termination of Agreement With 1416753 B.C. Ltd

Cranbrook, B.C., August 15, 2024: Eagle Plains Resources Ltd. (“EPL”:TSX-V, or “Eagle Plains”)

announces that 1416753 B.C. Ltd. (“1416753” has defaulted on the performance requirements of the

Option Agreement between 1416753 and Eagle Plains on the Acacia, Finlith, Lost Horse, Surprise and

Toodoggone Projects. Eagle Plains has formally notified 1416753 that the Option Agreement is

terminated.

See Lost Horse Project Summary Map here

The 3,759ha Lost Horse property is located in South-Central British Columbia, 99 km north of Kamloops

and 27 km west -southwest of Clearwater. Eagle Plains has recently received a 5 year MYAB permit for

the Lost Horse, which includes provisions for trenching and diamond drilling.

There is a single BC Minfile occurrence on the property, and many significant Minfile occurrences in the

areas immediately adjacent to the property boundaries . These include polymetallic veins in healed fault

breccia zones to the southeast of the property (HC Gold, HC Silver, and PGR showings), skarns along the

margins of dioritic intrusions to the south of the property (Silver, Wandering Dog, and Pycu showings),

and brecciated sedimentary and volcanic rocks hosting anomalous copper, molybdenum, lead, and zinc to

the north of the property (RO and FL showings).

The property area is underlain by arc volcanic, plutonic, and sedimentary rocks belonging to the Quesnel

Terrane that hosts several important mines in southern British Columbia. It covers known gold -silver-

copper-molybdenum-zinc veins and is a prospective target for copper -gold porphyry mineralization.

Outcrop exposure is generally low with the majority of outcrop/subcrop occurring along road cuts.

The earliest recorded work in the Lost Horse area dates to the 1930s, following the discovery of the

Lakeview copper-skarn occurrence (BC Minfile 092P 010) which resulted in several pits and an adit being

completed. Exploration activity renewed in the 1960’s for porphyry-style copper mineralization. Between

1966 to 1989, portions of the current property were part of larger projects belonging to United Copper

Corporation Ltd., Imperial Oil Limited, SMD Mining Co. Ltd., and BP Exploration Canada Limited. These

companies conducted programs which included soil geochemical sampling, geological mapping,

trenching, geophysical surveying, percussion drilling, and diamond drilling.

From 1988 through to 2009, exploration activity focus shifted to auriferous veins and alteration zones.

Lancer Resources Inc. and Rat Resources Ltd. conducted several soil sampling, trenching, and drilling

programs in 1988/89 within the current property boundaries . From 1992 to 1995, R.C. Wells, P.S. Watt,

and Electrum Resource Corp. conducted a series of small rock sampling, soil sampling, and stream -silt

sampling programs with rock grab samples returning from below detection up to 2.27 g/t Au, 2.05 g/t Au,

7.78 g/t Au (Zone A ) and 1.39 g/t Au , 5.66 g/t Au (Road Zone ) (BC AR 23716). In 1995 and 1997,

Cambridge Minerals Ltd. completed a trenching and drilling program (Road Zone) which returned 7.95

g/t Au over 0.5m (BC AR24122) and 0.735 g/t Au (BC AR24827) over 2.4m, respectively. From 1998 to

2009, Christopher James Gold Corp., Electrum Resources Corp., and Lithic Resources Ltd. completed a

number of smaller rock sampling, stream -silt sampling, airborne, trenching, and geophysical surveying

programs.

Eagle Plains Work Programs

In 2022, TerraLogic Exploration Inc. conducted an exploration program at the Lost Horse Property on

behalf of Eagle Plains Resources Ltd. which included soil sampling, stream silt sampling, rock sampling,

and geological mapping. The program was successful in confirming gold-silver-zinc mineralization on the

property. Gold-silver-zinc mineralization is primarily related to extensional, brecciated, sulphide -bearing

quartz veins hosted in altered andesite host rock. The results returned from this program indicated that the

Lost Horse property has significant prospective potential. Observations in 2022 suggest that mineralization

on the property is likely related to low-sulphidation epithermal veining which could also indicate a buried,

mineralized porphyry in the region.

TerraLogic Exploration recently completed the 2024 field program at the Lost Horse. Fieldwork included

mapping and prospecting, till sampling and tight spaced soil sampling in areas of interest identified with

past work. Results from the 2024 program are pending.

The property is 100% owned by Eagle Plains Resources with part of the property subject to an underlying

0.5% Net Smelter Royalty in favor of an arms-length third party. The Lost Horse project is available for

option and Eagle Plains is actively seeking partners.

Rock grab samples are selective samples by nature and as such are not necessarily representative of the

mineralization hosted across the property. The above results were taken directly from MINFILE

descriptions and assessment reports 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.
