Eagle Plains’ Partner Rockridge Resources Plans Upcoming Fully Funded Exploration and Drill Program at the Knife Lake Copper Project, Saskatchewan
Cranbrook, B.C., March 31st, 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”) plans for an upcoming Summer 2022 drill program at the Knife Lake Copper Project VMS Project located in Saskatchewan, Canada (the “Knife Lake Project” or “Property”). Using the results and interpretation from the Fall and Winter 2021 field programs, as well as the 2021 drill program, the upcoming program will target the Gilbert West and Gilbert South zones in addition to continued infill and expansion drilling at the deposit. Rockridge is fully funded for this upcoming exploration and drilling having recently closed a financing. The Knife Lake Project, consisting of 82 claims totaling 56,865 hectares (140,516 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’s CEO, Jonathan Wiesblatt, commented: “Exploration at Knife Lake, specifically at the target areas outside of the existing resource, offer compelling discovery potential as there has been limited historical work done on these highly prospective targets. Getting back to Knife Lake and conducting a thorough drilling campaign focused on the Gilbert West and Gilbert South zones is a priority for Rockridge as well as expanding and upgrading the resource at Knife Lake. The project remains an exciting exploration story that can offer investors exposure to a top mining jurisdiction and to commodities in high demand and short supply such as copper and zinc. We look forward to updating our shareholders as we prepare and work towards commencing the upcoming work at Knife Lake.”
Rockridge received and previously announced results from a field program completed in October of last year. A two-person field crew was mobilized to complete mapping and prospecting at regional target areas, investigating conductivity and magnetic anomalies identified through the Phase I (Winter 2021) and Phase II (Fall 2021) airborne geophysical programs (VTEM).

A total of 29 samples were submitted for assay, 26 samples from regional targets and 3 confirmation samples from historic trenches at the Knife Lake Deposit. Two samples collected from historic trenches at the Knife Lake Deposit returned significant results and are summarized in the table below.

Prospecting on the west side of the Gilbert Lake target identified altered volcanic and green pegmatite lithologies consistent with the host rocks at the deposit, indicating continuity of favourable stratigraphy approximately 10 km west of the deposit. Field geologists reported visual confirmation of trace interstitial chalcopyrite hosted within the green pegmatite interval.
Plans for Upcoming Diamond Drilling Program
The drill program at the Gilbert North and South target areas in 2021 was designed to evaluate conductivity and magnetic anomalies identified during the early 2021 airborne VTEM Plus survey and corresponding surficial geochemical anomalies. It was the first modern drill program that tested these target areas and several drill intercepts included pyrrhotite-pyrite dominant VMS-style mineralization hosted at the same stratigraphic horizon as the Knife Lake Deposit. Following the initial drilling at the Gilbert North and South targets a Borehole Electromagnetic survey of all holes at the Gilbert North and South target areas was completed to refine future drill targets which will be tested in this upcoming program. Furthermore, previous surficial work programs have indicated that the stratigraphic position of the targeted anomalies correlates with the Knife Lake Deposit to the east. The discovery potential at the broader 15 km Gilbert trend is robust and warrants follow up work which is being planned in this upcoming program. Rockridge continues to utilize modern exploration techniques and methods with the goal of making new discoveries.

Drill targeting for the fully funded 2022 diamond drill program is currently underway and management is assessing high priority targets that include additional drill testing in the Gilbert South Area. The planned holes will further investigate strike-length continuity of the mineralized horizon intersected in 2021 drilling, which remains open to the south. The holes will also evaluate potential zoning of mineralization, which is commonly observed in VMS systems. Additional holes at a newly discovered copper showing at the Gilbert West Area are also being considered. The holes will target the down-dip extension of a mineralized and intensely altered volcanic package which is interpreted to be the Knife Lake stratigraphic horizon. The Gilbert West target has never been drill tested. The Company is also evaluating drill targets at the Knife Lake deposit with the intention of testing deeper targets below the existing deposit and infill drilling to upgrade inferred resources to indicated resources.
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 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 14th, 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.
