Eagle Plains’ Partner Rockridge Resources Commences Exploration Program

at the Knife Lake Copper Project, Saskatchewan

Cranbrook, B.C., September 8th, 2021: Eagle Plains Resources (TSX -V:EPL) is pleased to announce

that option partner Rockridge Resources Ltd. (TSX-V: ROCK) (OTCQB: RRRLF) (Frankfurt: RR0)

(“Rockridge”) has commenced its field program at the Knife Lake Copper Project located in Saskatchewan,

Canada (the “Knife Lake Project” or “Property”). The Knife Lake Project, consisting of 81 claims totaling

55,471 hectares (137,069 acres), is an advanced-stage copper, silver, zinc and cobalt exploration property

in Saskatchewan host to the Knife Lake Deposit.

Rockridge holds the exclusive o ption from Eagle Plains to acquire a 100% interest in the Property that

covers the Knife Lake Cu-Zn-Ag-Co VMS deposit (details following). The contiguous claims are located

approximately 50 km northwest of Sandy Bay, Saskatchewan. A 357kV powerline runs within 16 km of

the Knife Lake Deposit area.

Crews have commenced a helicopter-borne electromagnetic (EM) and horizontal magnetic gradiometer

geophysical survey utilizing Geotech Ltd.’s VTEM Plus System . The 610 line kilometer survey has been

designed to investigate over 30 kilometers of highly prospective VMS stratigraphy, never before surveyed

using modern time-domain geophysics. Mineralized drill intersections at the Gilbert Lake target area have

proven that VTEM plus is a valuable exploration tool for identifying VMS-style mineralization within

prospective stratigraphy on the Property, increasing discovery potential in regional target areas. Combined

with surficial geochemical data and geological mapping, results from the current program will help identify

and prioritize additional drill targets.

Knife Lake Geology and History

The Knife Lake Deposit is interpreted to be a remobilized VMS deposit. The stratabound mineralized zone

is approximately 15m thick and contains copper, silver, zinc, gold and cobalt mineralization which dips 30°

to 50° eastward over a known strike -length within Rockridge’s claim area of 3,700 metres, and a known

average down-dip extension of approximately 300 metres.

The deposit i s hosted by felsic to intermediate volcanic and volcaniclastic rocks which have been

metamorphosed to upper amphibolite facies. The deposit contains VMS mineralogy which has been

significantly modified and partially remobilized during the emplacement of gr anitic rocks. The

mineralization straddles the boundary between two rock units and occurs on both limbs of an interpreted

overturned fold.

Rockridge has completed twenty-four holes consisting of 3096 metres of diamond drilling in the 2019 and

2021 winter drilling programs. This represented the first drilling on the property since 2001. Both programs

have given Rockridge’s technical team valuable insights into the property geology, alteration, and

mineralization that will be applied to fu ture regional exploration on the highly prospective and

underexplored land package.

Highlights from the drill program s include previously reported hole KF19003 which intersected net -

textured to semi-massive sulphide mineralization from 11.2m to 48.8m downhole. This 37.6 metre interval

returned 2.03% Cu, 0.1 9 g/t Au, 9.88 g/t Ag, 0. 36% Zn, and 0.01% Co for an estimated 2.42% CuEq.

Additionally, previously reported drill hole KF19001 intersected net -textured to fracture -controlled

sulphide mineralization from 7.5 metres to 40.6 metres downhole. This 33.1 metre interval returned 1.28%

Cu, 0.12 g/t Au, 4.80 g/t Ag, 0.13% Zn, and 0.01% Co for an estimated 1.49% CuEq.

In August 2019, Rockridge announced a maiden NI 43 -101 resource estimate for the Knif e Lake deposit

which consisted of a pit-constrained indicated resource of 3.8 million tonnes at 1.02% CuEq and an inferred

resource of 7.9 million tonnes at 0.67% CuEq using a 0.4% CuEq cut-off. For more information please

refer to the News Release dated August 14 th, 2019 or the NI 43-101 Technical Report on the Mineral

Resource Estimate for the Knife Lake Property, Saskatchewan dated September 27, 2019, filed on Sedar.

Knife Lake Option Agreement Details

To earn a 100% interest in the Knife Lake Project, Rockridge has agreed to make a cash payment to Eagle

Plains of $150,000 (complete), issue up to 5,550,000 common shares of Rockridge (2,750,000 shares issued

to date) and complete $3,250,000 in exploration expenditures ($1,195,000 to date) over four years. Eagle

Plains will retain a 2% net smelter royalty (“NSR”) on certain claims which comprise the project area.

Under the terms of the agreement Rockridge is designated as the Operator of the project.
