Rockridge Plans Upcoming Summer Exploration Program at the Knife Lake Copper Project, Saskatchewan

Rockridge Resources Ltd. (TSX-V: ROCK ) (OTCQB: RRRLF ) (Frankfurt: RR0 ) ("Rockridge" or the "Company") is pleased to announce 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.

Field crews will be mobilizing for a fully funded and 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.

The Company 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 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 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.

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 the #3 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.
