Rockridge Resources Ltd. announced further sampling and prospecting results from the 2021 exploration program at the Knife Lake Copper VMS Project located in Saskatchewan, Canada. 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 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). 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 favorable 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 Rockridges planned upcoming diamond drill program. 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 Rockridges 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.
