Eagle Plains' Partner Rockridge Resources Plans Upcoming Summer Exploration Program at the Knife Lake Copper Project, Saskatchewan

CRANBROOK, August 10, 2021 - Eagle Plains Resources (TSXV:EPL) is pleased to announce that option partner Rockridge Resources Ltd. (ROCK)(RRRLF)(RR0) ("Rockridge") plans for an upcoming 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 option 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.

Rockridge will be mobilizing field crews and fully funding this permitted summer/fall 2021 exploration program designed to follow up on the encouraging results from the recent 2021 winter/spring diamond drill and geophysical programs. The upcoming field program will include a helicopter-borne electromagnetic (EM) and horizontal magnetic gradiometer geophysical survey utilizing Geotech Ltd.'s VTEM Plus System. 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 of regional target areas. The upcoming program will expand on the previous survey, utilizing modern geophysical techniques coupled with surficial geochemical data and geological mapping to generate drill-ready regional targets to be tested during Rockridge's planned follow-up diamond drill program later in the year.

Rockridge's CEO, Jonathan Wiesblatt, commented: "Knife Lake is an exciting VMS exploration project in a well-known and highly prospective mining jurisdiction in Canada. Although the Knife Lake deposit was discovered some time ago the areas surrounding the deposit including recently identified regional targets must be followed up on as there are strong indications of additional discoveries to be made nearby. We are excited to get back to work at the Knife Lake Property and are encouraged by the results we received in our earlier exploration programs in the winter and spring of 2021. Each additional program is expected to improve our knowledge of the geology at Knife Lake and should help to advance our company towards new discoveries."

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 is 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 granitic rocks. The mineralization straddles the boundary between two rock units and occurs on both limbs of an interpreted overturned fold.

Rockridge completed twelve holes consisting of 1,053 metres of diamond drilling in the 2019 winter drilling program. This represented the first drilling on the property since 2001 and had two primary objectives: confirm the tenor of mineralization reported by previous operators and expand known zones of mineralization. Highlights from the drill program included 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, 0.19 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.

Compilation and initial modelling indicate potential for expansion of the deposit at depth. The recent drilling focused on resource upgrade as well as infill drilling between historical holes. The program gave Rockridge's technical team valuable insights into the property geology, alteration, and mineralization that will be applied to future regional exploration on the highly prospective and underexplored land package.

The Knife Lake deposit is a near surface VMS deposit starting a few metres below surface and the deposit remains open at depth and along strike for potential resource expansion. Recently Rockridge announced a maiden NI 43-101 resource estimate for the Knife Lake deposit (see the News Release dated August 14^th, 2019) which consisted of an indicated resource of 3.8 million tonnes at 1.02% CuEq at a 0.4% CuEq cut-off (3.8 MT at 0.83% Cu, 3.7 g/t Ag, 0.097 g/t Au, 82 ppm Co, 1740.7 ppm Zn). In addition, there is an inferred resource of 7.9 million tonnes at 0.67% CuEq at a 0.4% CuEq cut-off (7.9 MT at 0.53% Cu, 2.4 g/t Ag, 0.084 g/t Au, 53.1 ppm Co, 1454.9 ppm Zn). Refer to 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.
