Eagle Plains Completes Airborne Geophysical Survey at Theory

Copper-Gold Project in the Toodoggone District

Cranbrook, B.C., July 30, 2024: Eagle Plains Resources Ltd. (“EPL”:TSX-V, or “Eagle Plains”) has

completed a property wide, high resolution airborne magnetic and radiometric survey at it’s 9156 ha

Theory Copper-Gold project, located in the Toodoggone Mining District of British Columbia. Precision

GeoSurveys was contracted for the survey and collected approximately 1000 line kilometers of data at

100m line spacing. Geophysics at this scale has never been completed on the project and will serve as an

excellent foundation to begin evaluating the property and plan future work. The survey will also cover the

520 ha Gold Mountain Project, located ~3 kilometers east of the main Theory claim block. Interpretation

of the results will begin once final deliverables are received from the contractor. The program is being

managed by Terralogic Exploration Inc. of Cranbrook, BC.

The Theory project is considered to be highly prospective for both epithermal gold and copper -gold

porphyry deposits. The property is owned 100% by Eagle Plains, with 122 hectares of the property subject

to an underlying 0.5% Net Smelter Royalty held by a third party.

Theory Project Highlights

• Large contiguous land position

• Located in highly prospective Toodoggone Copper & Gold Mining District

• Multiple occurrences of low-sulphidation quartz-carbonate gold-silver veins

• Presence of argillic and propylitic hydrothermal alteration

• Favourable geological setting including a significant extent of the "Red-Line”

unconformity

• Last significant exploration was 1988 with no modern geophysics or drilling

The 9156 ha Theory Property is located in northern BC within the Toodoggone Mining District. The

district is endowed with both epithermal gold and porphyry copper -gold deposits, most notably the past

producing Kemess Mine owned by Centerra Gold. The Omineca Resource Road provides access to the

region from Mackenzie, BC. Recent road upgrades completed in 2023 by Thesis Gold on their Lawyers -

Ranch Project brought road access to within 8 kms of the Theory property.

Geology in the Theory region is primarily comprised of lower Jurassic Hazelton Group volcanics which

unconformably overlie late Triassic Takla Group volcanics. The entire package of rocks is intruded by

late Triassic and early Jurassic stocks. The majority of the Theory property encompasses the highly

prospective Jurassic-Triassic unconformity (~200 Ma), termed by the BC Geologic Survey as the ‘Red-

Line’, which is known to have a high spatial correlation to many of the known deposits throughout the

Golden Triangle and Toodoggone.

Although exploration within the property boundaries by previous operators has been intermittent since the

mid-60’s and regional government surveys are limited, encouraging mineralization and alteration

commonly associated with both epithermal and porphyry systems has been documented.

Exploration success in the area has been highlighted by the recent announcement by Thesis Gold at their

Lawyers-Ranch Project of a combined Measured and Indicated Mineral Resource of 4.0 Moz and an

Inferred Mineral Resource of 727 Koz at respective grades of 1.51 and 1.82 g/t AuEq. (Thesis Gold, May

1, 2024 News Release)

In late 2023 Eagle Plains acquired the property through staking and third-party agreements. Detailed

compilation and interpretation of available data from historical work programs is ongoing and, combined

with the results from the airborne survey, will lead to recommendations for future work.

The Theory project is available for option and Eagle Plains is actively seeking partners.

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.
