Rockridge Resources [TSX-V: ROCK] Report Strong Drill Results and New Top-Tier CEO
Rockridge Resources (TSX-V: ROCK) / (Frankfurt: RR0) is an exploration company focused on acquiring, exploring & developing mineral resource properties in Canada. Its focus is copper & base metals; more specifically — base, green energy & battery metals — of which copper is all three. Not just in any place, only top-tier mining jurisdictions such as Saskatchewan. And, only in mining districts that have had significant past exploration, development or production. And, only projects in close proximity to key infrastructure. Rockridge’s management team, Advisors & Board expertly and methodically eliminate many risk factors, early on, that can kill projects. This is a tremendous team for a company with a market cap of just C$5.6M / US$4.2M
New CEO Bolsters Already Strong Team
Late last month, Rockridge appointed Grant Ewing, P.Geo to be its new CEO. Jordan Trimble remains as President & a Director. Grant has > 25 years’ experience in the Metals & Mining space. His expertise covers the entire mine development cycle, from early-stage exploration through to production. I spoke with Grant last week and was impressed with his extensive knowledge of base metals and his understanding of the district that hosts the Company’s flagship project, Knife Lake. Grant seems to be an ideal person to help advance the Project and make new discoveries. Please see more about CEO Grant Ewing, P.Geo here.
The Company’s primary project, Knife Lake, is in Saskatchewan, Canada, (ranked 3rd best mining jurisdiction in the world) in the Fraser Institute Mining Company Survey. The Project hosts a near-surface, (high-grade copper) VMS copper-zinc-silver-gold-cobalt deposit, open along strike and at depth. Management believes that there’s strong discovery potential in and around the deposit area, and at additional targets on the roughly 85,200 hectares of contiguous claims. As a reminder, Rockridge has an option agreement with Eagle Plains Resources to acquire a 100% Interest in the majority of the Knife Lake VMS deposit.
Flagship Project, Knife Lake, 12 Drill Hole Results Now in….
The Project is within the famous Flin Flon-Snow Lake mining district that contains a prolific VMS base metals belt. Management believes there’s tremendous exploration upside. The goal? High-grade discoveries in a mineralized belt that could host multiple deposits, as VMS–style zones often contain clusters of mineralized zones.
However, no modern exploration, drilling or technology has been deployed at Knife Lake. It was discovered 50 years ago and last explored in the late 1990s. Airborne geophysics, regional mapping & geochemistry was done, but technologies have improved. Management believes that modern enhancements in geophysics; high resolution, deep penetrating EM and drone mag surveys covering large areas in detail, could make a big difference.
Earlier this year, Rockridge drilled 12 holes for a total of 1,053 meters. Importantly, this represents the first work on the property since 2001. Readers may recall from reading past articles & interviews on Epstein Research & Equity.Guru & Aheadoftheherd, and viewing videos of then CEO Trimble, that the Company’s primary goal is to explore districts that have been under-explored, never explored, or not recently explored. Management’s highly skilled & experienced technical team & advisors deploy the latest exploration technologies & methods. A lot has changed in 18 years; a simple example would be the use of lower-cost, high resolution drones to fly various surveys.
These 12 assays, added to the historical database, will generate a new NI 43-101 mineral resource estimate in late July or early August. This will be a major milestone that will hopefully draw the attention of prospective strategic partners. Subsequent to that de-risking event, Rockridge is funded for a Summer exploration program, that will likely stretch into Fall. The goal is to identify & refine targets at depth and regionally. Modern vectoring techniques will be deployed, using metal ratios & structural interpretation to identify “primary” VMS deposits.
Other modern methods include high-resolution geophysics, deep penetrating EM to identify conductors, and, as mentioned, drone mag surveys to cover large areas in detail. Finally ground work & sampling will be conducted, analyzing rock geochemistry to identify prospective VMS style hydrothermal systems. Importantly, very limited previous drilling was done below 100m, but of the deeper holes, several intersected mineralization at around 300m. Could they be mineralized lenses?
Best Intercept From First 5 Holes; 37.6 m of 2.42% Cu Eq.
Last month Rockridge reported additional results from its Winter diamond drill program. The first 5 holes are shown in the chart above. Readers may recall that a key takeaway was that holes KF19001 & KF19002 largely confirmed historical grades, intercept widths & geological conditions. Hole KF19003, reported on May 7th, was a blockbuster, 37.6m of 2.42% Cu Eq., significantly better than the first 2 holes. KF19003 had a grade (Cu Eq.) x thickness (in meters) value of 91, compared to 41 & 49. Importantly, it confirmed high-grade mineralization up-dip of KF19002 in an area where no historical drilling is known to have been done. Therefore, this assay, and perhaps nearby assays to follow, could potentially increase the size & grade of the upcoming mineral resource estimate.
Best Intercept in Last 7 Holes: 15.2 m of 2.45% Cu Eq.
In today’s press release June 10th, holes KF19006 thru KF19012 did not contain any blockbusters, but 6 of 7 were nicely mineralized with Cu Eq. values ranging from 0.46% to 2.45%. The interval widths averaged nearly 8 meters. The best intercept was 15.15 m at 2.45% Cu Eq. in hole KF19006. This intercept is a good one, like those found in holes KF19001 & KF19002, reported in the April 30th. press release. Importantly, KF19006 tested the up-dip extension of the Knife Lake deposit in an area that had not been previously tested. Likewise, hole KF19007 tested the down-dip extension of the deposit near KF19006. KF19007 intersected a solid 2.95 m of 0.82% Cu Eq. grade.

Rockridge’s CEO, Grant Ewing commented:
“The Knife Lake property package is highly prospective for new discoveries using modern exploration techniques & methods given the lack of recent field work. The known deposit is thought to be a remobilized portion of a presumably larger primary VMS deposit, and there is excellent potential for deposit expansion at depth which we plan to test in future programs. Furthermore, there are several high quality targets to test on the expansive landholding, and there have yet to be satellite deposits discovered in the vicinity as VMS systems often host clusters or stacked deposits.”
Something I found interesting was the 2 portions of the 15.2 m intercept in KF19006 that assayed 7.25 m of 0.72 g/t Gold, (from 8.75 to 16.0 m), and 5.0 m of 0.93 g/t Gold, (from 11.0 to 16.0 m), both within 16.0 m of surface. Those 2 grades (true widths undetermined) are the highest Gold values reported to date. The 0.93 g/t showing is nearly 50% higher, and 1.0 m longer, (5.0 vs. 4.0 m) than the next highest grade Gold showing, in blockbuster hole KF19003. While intriguing, these values in isolation may not amount to much. Still, it’s worth keeping an eye on.
