Het ziet er naar uit dat Canada Cobalt z'n naamswijziging weer ongedaan moet maken.


Canada Cobalt Drills into Bonanza Grades at Castle

COQUITLAM, BC, Feb. 19, 2019 /CNW/ - Canada Cobalt Works Inc. (TSXV: CCW) (OTC: CCWOF) (Frankfurt: 4T9B) (the "Company" or "Canada Cobalt") is pleased to announce that first-pass underground Phase 1 drilling on the first level of the Castle mine near Gowganda, 75 kilometers from Kirkland Lake, has returned multiple high-grade cobalt and silver intercepts at very shallow depths.

Drill results have also revealed areas overlooked by historical explorers that show potential to host very high-grade "shoots" of silver and cobalt-silver mineralization, mixed with occasional nickel and gold, that may extend to considerable depths outside of historical drilling or workings.

Highlights:

New discovery of very high-grade silver vein structures approximately 55 meters southwest of the #3 Shaft where a silver discovery in 1979 put the Castle mine back into production for a decade - CA-18-54 cut 93.7 ounces per ton Ag (3,213 grams per tonne) over one meter including 286.3 ounces per ton (9,816 g/t) over 0.33 meters starting just 9.71 meters downhole, with the hole drilled across the structure at 25o to core axis and then bottoming in high-grade mineralization from 18.84 meters to 20.50 meters;
385.2 ounces per ton silver (13,208 g/t), 0.67% cobalt and 3.77 g/t gold over half a meter within a broader 5.51-meter zone that also included 1.87% cobalt over 2.54 meters and 76.4 ounces per ton Ag (2,620 g/t) over a core length of 5.51 meters starting at just 1.46 meters (CA-18-02, collared near the adit entrance, was drilled perpendicular to the strike of the targeted vein structure, sub-parallel to the dip of the vein);
All 47 assayed shallow underground test holes intersected cobalt mineralization with an impressive one-quarter of those holes returning high-grade intercepts of 1.05% to 3.7% cobalt over an average core length of 1.77 meters (true widths unknown at this time);
A series of key initiatives, already in motion, will drive an expanded Phase 2 program to immediately build on these results and accelerate the broader 2019 corporate goal to leverage the company's proprietary Re-2OX technology simultaneously with heightened activity at the Castle mine in ways that continue to keep CCW share dilution to a minimum.
Jacques Monette, Canada Cobalt Director and career miner, commented: "These results from our first-ever underground drilling support the interpretation that much was left behind at the Castle mine, not just cobalt but very high-grade silver. This array of high-grade intercepts at shallow levels further energizes our team as we ramp up again and implement a greatly expanded second phase of our underground strategy.

"2018 was a pivotal year in the revitalization of the Castle mine," Monette continued, "and we look forward to achieving key new milestones in the coming months. At the height of winter, we have a very active site and another drill program kicking off this week southeast of the mine as we build on a potential high-grade gold discovery at Castle East. This is an exciting new development as the Archean rocks east of the high-grade silver mines were never tested historically."

Next Action Steps Underground

Immediate priority is follow-up drilling targeting high-grade "shoots" near #3 Shaft and adit entrance;
Through discussions with Canada Cobalt's engineering consultant, and the Northern Ontario Ministry of Mines and Development, all material from the first level stopes will be dumped and removed in accordance with an amended advanced exploration permit (notably, Canada Cobalt can produce gravity concentrate on site). The stopes will then be available for back-filling with cemented tailings as part of a major new program involving Re-2OX that Canada Cobalt will be elaborating on in the very near future;
As part of the amended exploration permit, blasting will be undertaken throughout the first level;
Hydrogeological studies will evaluate dewatering of the remaining 10 levels of the Castle mine.
Underground Drilling Highlight Details

#3 Shaft Area

Drill hole CA-18-54 hit two very high-grade silver intercepts starting just 9.71 meters downhole, 93.7 opt (3,213 g/t) over one meter including 286.3 opt (9,816 g/t) over 0.33 meters, followed by 11.8 opt (406.1 g/t) over 1.66 meters at the bottom of the hole beginning at 18.84 meters. Drilling was across these structures, with the first intercept at 25o to core axis and the latter intercept cutting a new vein at a lower angle than the first intercept. This is a new discovery where there was limited previous work - follow-up drilling will track the vein, and potential associated veins, to depth.

Adit Entrance Discovery

A further review of historical work in addition to Canada Cobalt drilling including updates of previously released preliminary data, suggests a silver-cobalt rich vein intersected near the adit entrance in the first three drill holes may also extend much further to depth. CA-18-02 was one of several holes that attempted to follow the vein from a series of inclinations from approximately the same drill set-up through the Nipissing Diabase toward the second level in order to test grade potential. Veining is irregular, so contacts averaged approximately 25 degrees to core axis (refer to Nov. 2, 2018 news release).

High-Grade Cobalt Values Confirmed

For the first time at the Castle mine, high-grade cobalt values, along with occasional nickel and gold, have been confirmed through drilling to exist in vein structures, and as much as 174 meters apart (collar to collar) from near the adit entrance (23 meters below shaft collar) to the #3 Shaft area.

Multiple Target Areas Throughout Expansive First Level

Phase 1 drilling has provided the Canada Cobalt geological team with multiple highly prospective new targets for detailed follow-up utilizing a more versatile and powerful drill rig that can track high-grade veins to depth. Many vein structures have yet to be tested. Based on historical mining data, veins at Castle are known to pinch and swell and move in and out of high-grade and lower grade mineralization over considerable distances. The first level (there are 11 in total) is in excellent condition with a footprint of 365 meters east-west and 360 meters north south. A total of 58 holes were completed (47 have been assayed) in Phase 1, totaling 675 meters. A table of assay highlights/details will be posted on the Canada Cobalt web site.

Canada Cobalt Adds $500,000 From Exercise of Warrants

Canada Cobalt has received approximately $500,000 from the exercise of warrants over the past two months and will continue its Northern Ontario Cobalt Camp leading practice of keeping share dilution to a minimum while aggressively advancing its exploration and development strategies in a cost-effective manner.

Scientists find new way to power electric cars using cobalt
Valentina Ruiz Leotaud | 2 days ago |

Researchers at the University of Massachusetts Lowell developed a technique that uses only water, carbon dioxide and cobalt metal particles that have surface nanostructures measuring billionths of a meter in size, to produce hydrogen on demand at relatively low temperature and pressure and to use to power the next generation of electric vehicles.

According to David K. Ryan, the project's principal investigator, hydrogen can be used in fuel cells, which combine hydrogen with oxygen from the air to produce electricity at up to 85% efficiency.

“Other investigators have used all kinds of methods to produce hydrogen, such as electrolysis, natural gas reforming and even metals such as zinc, iron and nickel with acids, but not catalytically with cobalt," Ryan said in a media statement. "The carbonate is involved in the reaction but it doesn’t change or get consumed; it just helps facilitate the conversion of the cobalt metal to cobalt oxide, and this conversion produces the hydrogen and carbon dioxide.”

The scientist explained that the experimental setup consists of a stainless steel canister filled with cobalt. A carbonate solution made from carbon dioxide and water is pumped through the canister and then warmed up to about 150 degrees. The solution is also compressed to about three atmospheres, or 45 pounds per square inch, which is about the same pressure as in a car tire.

“Under these relatively low-temperature and modest-pressure conditions, we were able to produce hydrogen efficiently, to nearly 70%. Subsequent work has allowed us to produce hydrogen at greater than 95% purity,” Ryan said.

The researcher explained that in an electric car, the hydrogen from the canister can go directly to the fuel cell, where it is mixed with oxygen from the atmosphere to produce electricity and water. The water can then be looped back into the canister and mixed with the carbonate to form the catalytic solution. The electricity produced by the fuel cell can be used to power the canister’s pump, heater and compressor, as well as the car’s electric motors, rechargeable storage battery and headlights.

“This process doesn’t store any hydrogen gas, so it’s safe and poses no storage or transportation issues. Once you stop the flow of the carbonate solution or release pressure in the reaction chamber, the hydrogen production stops, so hydrogen is produced only as needed,” Ryan said.

The experts suggested that once the cobalt metal in the canister is used up – that is, converted to cobalt oxide – the car driver can swap out the canister with a new one every 300 to 400 miles. The cobalt in the old canister can then be regenerated, using a renewable energy source such as wind or solar.

“So instead of going to a gas station to get a fill-up, you can go to a ‘refueling’ station and get a new canister. You can also bring extras for long trips,” Ryan said.

De vloek van het kobalt

De grondstof is onmisbaar voor de productie van onze elektrische auto’s, en daarmee voor een schonere lucht. Maar het delven ervan gebeurt vaak onder mensonterende omstandigheden. Het FD reisde naar de kobaltmijnen van Congo. ‘De Chinezen manipuleren de weegschalen!’
