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 geochemistry. These geophysical models will assist in targeting holes for the upcoming drill program.

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.

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.
