Rockridge Resources Ltd., a new public mineral exploration company, has reported the completion of its 3D Geophysical Plate Modeling of the VTEM data that has recently been acquired.
The gathered data will be utilized to improve the targeting for Rockridge’s forthcoming drill program commencing in mid-July 2022 at its Knife Lake High-Grade Copper VMS Project situated in Saskatchewan, Canada. Rockridge has been completely funded and permitted for this drill program.
The Company also declared that the VTEM survey data exhibits up to 15 km strike length of near-surface anomalies that seems to be highly conductive and is hosted in prospective stratigraphy in regional target regions.
The regional target regions, including the Gilbert Lake Targets, were determined earlier via surface sampling, geological mapping, and geochemical analyses as stratigraphy with an ability to host valuable copper happenings and other sulfide mineral occurrences. This stratigraphy has been interpreted to be the same horizon that tends to host the Knife Lake Deposit.
We are very excited for the upcoming drilling at our flagship asset and look forward to potentially making a new discovery and advancing the project. The 3D modeling of the five plates has confirmed our strategy that the Gilbert Lake Target will be the primary focus on this upcoming drill program in mid-July 2022.
Jonathan Wiesblatt, CEO, Rockridge Resources Ltd.
Wiesblatt added, “The project remains an exciting exploration story that can offer investors exposure to a top mining jurisdiction and to commodities in high demand such as copper, cobalt, and zinc. We look forward to updating our shareholders in the coming weeks.”
Updates for Upcoming Diamond Drilling Program
The focal point of the 2022 drill program will be on the extremely prospective Gilbert Lake target area. The Gilbert Lake targets were determined from the outcomes and interpretation of the 2021 geophysical, field, and drill programs.
Outcomes obtained from such programs display that airborne VTEM surveys could be successful in determining zones of VMS-style mineralization hosted in favorable stratigraphy on the property. Moreover, the Company has currently finalized the 3D modeling of the VTEM data concentrating on the highest-priority drill targets for the program that is to come in the future.
Rockridge has signed all significant contracts such as the camp construction, helicopter rental, and drill contractor. The drill program has been scheduled to start in mid-July 2022. The Company has also been granted an Exploration Permit that expires in February 2024, meaning that it could also carry out geophysical works, drilling, and prospecting.
Knife Lake Geology and History
The Knife Lake Deposit is a remobilized VMS deposit. The stratabound mineralized zone is about 15 m thick and contains copper, zinc, gold, silver, and cobalt mineralization which dips 30° to 50° eastward over a well-known strike-length inside Rockridge’s claim area of 3,700 m and a familiar average down-dip extension of nearly 300 m.
The deposit is hosted by felsic to intermediate volcanic and volcaniclastic rocks which have been metamorphosed into upper amphibolite facies. The deposit comprises VMS mineralogy which has been considerably altered and partially remobilized at the time of the emplacement of granitic rocks.
The mineralization overlaps the boundary between two rock units and happens on both limbs of a taken overturned fold.
The Company has completed 24 holes comprising 3,096 m of diamond drilling in the 2019 and 2021 winter drilling programs. This constitutes the first drilling on the property since 2001.
Both programs have provided the technical team of the Company with useful knowledge of the property alteration, geology, and mineralization that will be employed in future regional exploration on the highly prospective and underexplored land package.
Highlights obtained from the drill programs include earlier reported hole KF19003 which sectioned net-textured to semi-massive sulfide mineralization from 11.2 m to 48.8 m downhole. This 37.6 m interval returned 9.88 g/t Ag, 0.36% Zn, 2.03% Cu, 0.19 g/t Au, and 0.01% Co for an evaluated 2.42% CuEq.
In August 2019, Rockridge reported a maiden NI 43-101 resource assessment for the Knife Lake deposit consisting of a pit-constrained indicated resource of 3.8 million tons at 1.02% CuEq and an inferred resource of 7.9 million tons at 0.67% CuEq utilizing a 0.4% CuEq cut-off.
