Eagle Plains' Partner Rockridge Completes 3D Geophysics Modeling which Identifies 15 km Strike Length of Electromagnetic Conductors; Prepares for Fully-Funded Upcoming Drill Program at Knife Lake High-Grade Copper Project, Saskatchewan

CANBROOK, BC / ACCESSWIRE / June 29, 2022 / 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 completed 3D Geophysical Plate Modelling of the recently acquired VTEM data which will be used to further refine targeting for an upcoming drill program starting in mid-July 2022 at the Knife Lake High-Grade Copper VMS Project located in Saskatchewan, Canada (the "Knife Lake Project" or "Property"). Rockridge is fully funded and permitted for this drill program.

The VTEM survey data displays up to 15 km strike length of highly conductive near-surface anomalies hosted in prospective stratigraphy in regional target areas. The regional target areas, which include the Gilbert Lake Targets, were previously identified through geological mapping, surface sampling and geochemical analyses as stratigraphy with high potential to host valuable copper occurrences and other sulphide mineral occurrences. This stratigraphy is interpreted to be the same horizon that hosts 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's CEO, Jonathan Wiesblatt, commented: "We are very excited for the upcoming drilling at our flagship asset and look forward to potentially making a new discovery and advancing the project. The 3D modeling of the five plates has confirmed our strategy that the Gilbert Lake Target will be the primary focus on this upcoming drill program in mid-July 2022. The project remains an exciting exploration story that can offer investors exposure to a top mining jurisdiction and to commodities in high demand such as copper, cobalt and zinc. We look forward to updating our shareholders in the coming weeks."

Updates for the Upcoming Diamond Drilling Program

The focus of the 2022 drill program will be on the highly prospective Gilbert Lake target area. The Gilbert Lake targets were identified from the results and interpretation of the 2021 geophysical, drill and field programs. Results from these programs show that airborne VTEM surveys can successfully identify zones of VMS-style mineralization hosted in favourable stratigraphy on the property. Additionally, Rockridge has now finalized the 3D modeling of the VTEM data focusing on the highest-priority drill targets for the upcoming program. Rockridge has signed all major contracts including the drill contractor, camp construction, and helicopter rental. The drill program is scheduled to commence in mid-July 2022. Rockridge has also received its Exploration Permit which expires in February 2024 and hence can conduct drilling, geophysical works and prospecting.

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 the 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 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 future regional exploration on the highly prospective and underexplored land package.

Highlights from the drill programs 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, 0.19 g/t Au, 9.88 g/t Ag, 0.36% Zn, and 0.01% Co for an estimated 2.42% CuEq.

In August 2019, Rockridge announced a maiden NI 43-101 resource estimate for the Knife 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 (4,550,000 shares issued to date) and complete $3,250,000 in exploration expenditures 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.
