Canada Cobalt drills 4 m of 4.3 g/t Au at Castle East

2020-03-02 07:39 ET - News Release

Mr. Frank Basa reports


As a new high-grade silver discovery continues to build out at Castle East, with a major update expected in the coming days, Canada Cobalt Works Inc.'s geologists are learning more about the sulphide-rich Archean rocks with strong gold potential above and below the Nipissing diabase that were never systematically explored in the prolific past producing Gowganda silver camp.

The Castle Archean package, featuring favourable structural and geological characteristics in the southwest Abitibi greenstone belt, is now increasingly viewed as prospective for quartz-carbonate vein-type gold deposits as well as base metal and PGE mineralization following initial phase exploration by Canada Cobalt.

Matt Halliday, vice-president, exploration, for Canada Cobalt, commented: "It's not unusual to find different types of deposits in a mining camp, even a century or more after the birth of a camp such as Gowganda. The growing gold potential of the 78-square-kilometre Castle property, through first-pass drilling and a very limited amount of exploration to date, is a fascinating development and points to geological processes that were more complex and dynamic than previously recognized. This has our team very excited, though our highest priority for obvious reasons is the emerging new high-grade silver deposit at Castle East.

"Gold and other potential deposit types at the Castle property are being partly explored through our ongoing program targeting additional high-grade silver zones within broad areas of untested diabase immediately adjacent to three robust past silver producers (Castle, Capitol and O'Brien)," Mr. Halliday continued. "We look forward to important updates regarding this compelling high-grade grassroots silver discovery during this first half of March."

Castle property gold highlights:

  • The only gold-focused drill hole at Castle East completed in 2019 (CS19-19) has cut 4.3 grams per tonne gold over four metres and 1.5 g/t Au over 12.5 metres within a 30-metre mineralized zone (core length, true width unknown at this time) grading 0.70 g/t (vertical depth approximately 240 metres). This broad interval included one metre that returned 15.2 g/t Au.
  • CS19-19 was a 240-metre stepout southwest of the only hole drilled toward the north (out of several holes completed in 2018), which cut 2.07 g/t Au over 1.50 metres starting 109 metres downhole (CS18-15) and also featured long intervals of highly anomalous nickel-copper mineralization.
  • CS19-19 was also a 100-metre stepout west of 2018 drill hole CS-18-16W, which cut three separate intervals of gold mineralization including 5.5 g/t over 0.37 metre, 1.59 g/t over 1.32 metres within 6.15 metres grading 0.56 g/t, and 1.35 g/t over 1.27 metres within 2.12 metres grading 0.92 g/t (core lengths).
  • CS18-15, CS18-16 and CS18-16W all intersected wide intervals of highly anomalous nickel-copper mineralization.
  • Through initial drilling and prospecting, gold-bearing quartz-carbonate veins at Castle East are now known to extend for several hundred metres west to east and 200 metres north to south, from surface to vertical depths up to nearly 300 metres. This broad overall zone remains open in all directions (CS19-19 was collared approximately 1.3 km southeast of the Castle mine and 500 metres southwest of the Robinson zone high-grade silver discovery).
  • As an enhanced geological understanding develops around east-west- and north-south-trending structures, follow-up drilling will vector toward potentially richer mineralization.
  • First-pass drilling, surface sampling, trenching, boulder tracing, geophysics and MMI (mobile metal ion) soil surveys show structurally aligned anomalies indicative of a broad and robust hydrothermal system.
  • High-grade gold discovered for the first time in underground drilling within the diabase at the Castle mine, including 22.7 g/t Au over 0.30 m within a 2.4 m core interval grading 5.8 g/t Au (refer to Jan. 3, 2020, news release), is being investigated by SGS Labs for a possible association with the Archean rocks.

Strong exploration potential extends 17 km to northeast

A 2007 assessment report refers to anomalous platinum and palladium mineralization and the discovery of high-grade gold in the early 1900s on what is now the northern portion of the Castle property in the Shillington area near the Round Lake batholith, approximately 17 km northeast of the Castle East gold zone, which led to some small pits and a shaft to the 175-foot level. A series of drill holes by Golden Chalice Resources in 2005 failed to intercept high-grade gold but did outline an intriguing near-surface quartz breccia copper zone with a minimum strike length of 200 metres.

Drill intercepts (core lengths) noted in the above assessment report included 1.27 per cent copper over 12.30 metres (23 m to 35.30 m) and 5.67 per cent Cu over 0.50 metre (44.5 m to 45 m) in drill hole GCSH10; 1.74 per cent Cu over 3.5 metres in GCSH8; and 1.12 per cent Cu over four metres in GCSH9, also at shallow depths. This discovery, which could indicate the potential for an IOCG-type deposit, was never followed up on, also leaving multiple airborne and geophysical conductors unexplained or untested. Canada Cobalt acquired these highly prospective claims in the spring of last year when it expanded the Castle property to 78 square kilometres.

PDAC (Prospectors & Developers Association of Canada) investor presentation

Canada Cobalt is pleased to invite investors to a PDAC 2020 presentation by Matt Halliday, Canada Cobalt vice-president, exploration, focused on the company's high-grade silver discovery at Castle East. This presentation is at 4 p.m. on Monday, March 2, in room 803 of the South Building, Metro Toronto Convention Centre. The presentation is part of PDAC's corporate presentation forum for investors.


The Castle property is 15 km east of Pan American Silver's Juby gold deposit, 20 miles due south of Alamos Gold's Young-Davidson mine and 45 km southwest of Kirkland Lake Gold's Macassa complex.

Quality assurance/quality control

Core sampling, sample preparation, sample handling and transport all followed a protocol established by GoldMinds Geoservices that included a strict chain of custody from sampling to the laboratory. The geologists at GoldMinds inserted blanks and standards at random intervals in each batch of approximately 40 samples. The standards were prepared by ASL Analytical Solutions.

Samples were sent to ALS Laboratory (independent laboratory in Rouyn-Noranda). The one-half core samples were crushed to 80 per cent passing two millimetres, riffle splitting 250 g and pulverizing the split to have a pulp 80 per cent passing 75 microns. Samples were assayed using multiacid digestion and atomic absorption. Fire assay was used for gold grade determination.

The results from the combination of blanks, standards and the internal QA/QC met the quality criteria, indicating that Canada Cobalt can rely on the reported values.

The authors believe that the sample preparation, security and analytical procedures were adequate and well suited for the purpose of the 2018/2019 drilling program.
