ROCK hits high VMS grades in first five holes

 

 

 

 

 

Rockridge Resources (TSX-V:ROCK) is off to a flying start at its Knife Lake volcanogenic massive sulfide (VMS) deposit in Saskatchewan, with the first five holes of its 2019 drill campaign returning high-grade copper-gold-zinc-cobalt mineralization.

 

 

The company is aiming to confirm, and expand on, historical drilling with the goal of completing an NI 43-101-compliant resource on the property.

 

 

The 12-hole, 1,053-meter diamond drill program, completed this past spring, has two objectives: to confirm the tenor of mineralization (the percentage of metals found in the sulfides) reported by previous operators, and to expand known zones of mineralization.

 

 

Of the three holes reported today (link), May 7, all cut high-grade mineralization.  

 

Drill hole KF19003 returned a relatively broad, 37.6m intercept, starting from 11.6m downhole. The grades assayed at 2.03% copper, 0.19 grams per tonne (g/t) gold, 9.88 g/t silver, 0.36% zinc and 0.01% cobalt. In copper-equivalent (CuEq) terms, that’s 2.42%.

 

 

This hole also stood out for being in an area untouched by historical drilling.

 

 

“The results from drill hole KF19003, specifically 2.42% CuEq over 37.6m, have far exceeded our expectations and represents one of the best holes ever drilled on the project,” said Jordan Trimble, Rockridge’s President and CEO.

 

 

He added: “It is important to note that this drill hole was collared in an area where no historical drilling has been reported. As such these drill results are expected to have a positive impact on the historical resource.”

 

 

 

The next two holes had shorter intersections but good grades.

 

 

Hole KF19004 cut a 3.4m interval of sulfide mineralization that returned 1.01% copper, 0.08 g/t gold, 4.21 g/t silver, 0.19% zinc, and 0.02% cobalt for an estimated 1.25% CuEq.

 

 

A 4.5m section of drill core on hole KF19005, between 32.0 and 36.5m downhole, assayed 1.03% Cu, 0.06% Au, 3.98% g/t Ag, and 015% Co, or 1.2% CuEq.

 

 

The first two holes of the program returned quite broad intersections containing the same VMS metals. Assayed drill core on KF190001 saw 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. The 33.1m interval interval was between 7.5m and 40.6m downhole.

 

 

Previously reported diamond drill hole KF19002 returned 0.78% Cu, 0.07 g/t Au, 2.54 g/t Ag, 0.07% Zn, and 0.01% Co for an estimated 0.93% CuEq. The 43.8m interval was between 9.7m and 53.5m downhole.

 

 

All five holes drilled so far have also reported traces of rare metals indium and gallium.  Indium is used to make transistors and other electrical components. Silver-blue-colored gallium is found in some medical thermometers as a substitute for mercury, in semiconductors and to make mirrors.

 

 

Knife Lake is currently owned by Eagle Plains Resources (TSX-V:EPL). Under an option agreement, Rockridge can acquire the project by incurring additional exploration expenditures of C$2.5 million over three years, along with issuing 3,250,000 million shares.

 

 

The 85,196-hectare property is about 50 kilometers northwest of Sandy Bay, Saskatchewan and within the Flin Flon-Snow Lake mining district, a prolific greenstone belt. Since the initial discovery of mineralization in 1915, the Flin Flon camp has produced over 170 million tons of sulfide ore from 31 VMS deposits, worth over $25 billion.

 

 

Historically explored with over 400 diamond drill holes, Knife Lake is a VMS deposit with a 15m-thick mineralized zone containing copper, gold, silver, zinc and cobalt. This winter’s drill program was the first exploration done since 2001.

 

 

 

 

 

A historical (non NI 43-101-compliant) resource estimate completed in 1998 showed 20.3 million tonnes grading 0.6% copper, 0.1 grams per tonne gold, 3.0 g/t silver, 0.06% cobalt and 0.11% zinc. This includes a higher-grade zone of 11.0 million tonnes grading 0.75% copper.

 

 

The first work was carried out between 1969 and 1973, including airborne geophysical surveys and soil sampling. The 1969 discovery hole returned 2.37% copper over 4.48m, including 3.5% over 2.5m. These days, anything over 1% is considered high-grade copper.

 

 

Rockridge believes Knife Lake could be the remobilized (moved by granitic rocks) portion of a larger VMS deposit, based on the mineralogy, mineral textures and metal ratios found within the deposit.

 

 

It aims to test this thesis by drilling deeper below the deposit and around it.

 

 

Assay results from the remaining seven drill holes are expected to provide good news fodder for ROCK over the next several weeks.
