Rockridge has received 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).
Knife Lake VTEM Survey Coverage:

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.

Field crews were only able to investigate a limited number of high-priority regional targets and additional field work is required to adequately study the source of these newly defined regional conductors. Interpretation of field results and geophysical modelling is underway to further refine drill targets for Rockridge’s planned upcoming diamond drill program.
Rockridge’s CEO, Jonathan Wiesblatt, commented: “We are very pleased with these sampling results as we enter 2022 with robust discovery potential around the deposit and at regional targets that we plan to test with an upcoming drill program. The findings from geophysical programs and field work carried out in 2021 have refined existing targets and have identified new ones. We look forward to continuing to advance the Knife Lake Project as we believe there is significant value yet to be unlocked at the property.”
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 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. 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.

Kerry Bates, P.

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.
