Eagle Plains’ Partner Rockridge Resources Completes Airborne Geophysical
Program at Knife Lake Copper Project - Drilling Planned
Cranbrook, B.C., March 11th, 2021: Eagle Plains Resources (TSX-V:EPL) has been notified by option
partner Rockridge Resources Ltd. (TSX-V: ROCK) (OTCQB: RRRLF) (Frankfurt: RR0)
(“Rockridge”) that it has completed an airborne geophysical program the Knife Lake Project located in
Saskatchewan, Canada (the “Knife Lake Project” or “Property”). Rockridge also announces its plans for an
upcoming 1,600 metres minimum drill program. Rockridge has an option agreement with 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 total 32,663 hectares and are located approximately 50 km northwest of
Sandy Bay, Saskatchewan. A 357kV powerline runs within 16 km of the Knife Lake Deposit area.

Winter Geophysical Program
Crews have now completed an airborne electromagnetic (EM) and horizontal magnetic gradiometer
geophysical survey at the Knife Lake Project using Geotech Ltd.’s VTEMTM Plus system. The survey was
strategically located over the Scimitar and Gilbert Lake targets to investigate over 30 linear kilometers of
prospective VMS stratigraphy which hosts the Knife Lake copper deposit.

Preliminary data from the survey has revealed several conductive features of significant interest, eight
conductors have been prioritized for geophysical modeling based on their correlation with prospective
stratigraphy and favorable geo chemistry. These geophysical models will assist in targeting holes for the
upcoming drill program.

The Knife Lake deposit contains typical VMS mineralogy which has been significantly modified and
partially remobilized during the emplacement of granitic rocks. Therefore, the known deposit may represent
a remobilized portion of a presumably larger “primary” VMS deposit based on general observations about
the mineralogy, mineral textures and metal ratios in the deposit. Most of the historical work has con sisted
of shallow drilling at the deposit area with little regional work carried out and limited deeper drilling below
the deposit. As a result, there is strong discovery potential both at depth and regionally.
Upcoming Knife Lake Drill Program
Rockridge has recently commenced the mobilization of crew and equipment to complete a minimum of
1,600 metres diamond drill program consisting of 6-8 holes. Drilling will focus on discovering VMS style
copper deposits along newly defined conductors and at depth, underneath the Knife Lake deposit. Infill
drilling is also planned in the immediate area of the 2019 maiden resource. Downhole geophysics, borehole
electromagnetics (BHEM), will be utilized extensively throughout the program. Project management has
been contracted to TerraLogic Exploration Services of Cranbrook, BC.
Knife Lake Geology and History
The Knife Lake Project 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 hoste d 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 r epresented 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 repo rted 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, p reviously 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
the Company’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 gpt Ag, 0.097 gpt 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
gpt Ag, 0.084 gpt 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 (approximately $1,400,000 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.
