Rockridge Resources Ltd. (TSX-V: ROCK ) (OTCQB: RRRLF ) (Frankfurt: RR0 ) ("Rockridge" or the "Company") is pleased to announce 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.
Knife Lake VMS Project Location Map:
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 (Fall 2021) and Phase II (Winter 2021) airborne geophysical programs (VTEM).
Knife Lake VTEM and Grab Sample Survey:
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.
Knife Lake Target Areas 2022 Drill Program
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 Histor y:
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.
Knife Lake Deposit Map:
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.
The Company has completed twenty-four holes consisting of 3,096 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 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.
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.

About Rockridge Resources Ltd.
Rockridge Resources (TSX.V: ROCK) is a public mineral exploration company focused on the acquisition, exploration and development of mineral resource properties in Canada, specifically copper and gold. The Company's core copper project is the Knife Lake Project located in Saskatchewan which is ranked as a top mining jurisdiction in the world by the Fraser Institute. The project hosts the Knife Lake Deposit, which is a VMS, near-surface Cu-Co-Au-Ag-Zn deposit open along strike and at depth. There is strong discovery potential in and around the deposit area as well as at regional targets on the large property package. The Company's secondary asset is the Raney Gold Project, which is a high-grade gold exploration project located in the same greenstone belt that hosts the world class Timmins and Kirkland Lake lode gold mining camps. Recently reported drill hole RN 20-06 intersected 28.0 g/t gold over 6.0 metres at a shallow vertical level of 95 metres, which is the best result from the project thus far. Rockridge's goal is to maximize shareholder value through new mineral discoveries, committed long-term partnerships, and the advancement of exploration projects in geopolitically favourable jurisdictions.
