Copper North Mining drills porphyry copper-gold in northern B.C.

October 20th, 2016

by Greg Klein | October 20, 2016

Having released a PEA for its Carmacks copper-gold-silver project in the Yukon the previous week, Copper North Mining TSXV:COL reported drill results from the northern British Columbia Thor project on October 20. After two previous holes on the 20,000-hectare property’s Thor West area came up dry, a Thor East hole did better:

Hole TH16-01

  • 0.14% copper and 0.045 g/t gold over 107.6 metres, starting at 11.65 metres in downhole depth
  • (including 0.23% copper and 0.069 g/t gold over 37.13 metres)
  • (which includes 0.28% copper and 0.087 g/t gold over 23.85 metres)

True widths were unavailable.

show oxide-weathered granodiorite.

Traces of copper continue beyond that intercept to the end of the hole at 169.16 metres, the company stated. “The transition from stronger mineralization and quartz-veining at the top of the hole to weaker copper mineralization and phyllic alteration at depth suggests that drill hole TH16-01 may flank a mineralized porphyry centre.”

Next steps would include ground surveys at Thor East and evaluating multiple geochemical targets and alteration zones, the company added. Field work has already identified multiple targets over a four-by-six-kilometre area southeast of TH16-01.

“The large area of porphyry alteration and gossan zones remain an attractive exploration target,” commented president/CEO Harlan Meade. “The Thor project provides Copper North with an opportunity to explore for porphyry copper-gold type mineralization in the slopes and valleys 20 kilometres to the south of the Kemess South mine and mill complex.”

The former mine now lies within AuRico Metals’ (TSX:AMI) Kemess Underground gold-copper-silver property.

Copper North holds a 100% option on Thor, which has a road and power line passing through the property.

The company closed private placements totalling $279,050 this month.

Drilling to begin at Copper North Mining’s Thor project in B.C.

September 9th, 2016

In a program announced early last month, Copper North Mining TSXV:COL has a rig in place at its Thor project in northwestern British Columbia. The first hole will target Thor East Area 3, which hosts “numerous small veins with copper and gold, and extensive alteration zones,” the company stated.

Another hole will test the Thor West Area, defined by an induced polarization anomaly covering two kilometres by 2.5 kilometres, flanking a road to the former Kemess mine. Another Thor West hole has been planned 1.5 kilometres away, on the anomaly’s northern section.

Further drilling depends on results for these initial holes.

The campaign’s goal is porphyry copper-gold mineralization near the past-producing Kemess South open pit and mill complex, now within AuRico Metals’ (TSX:AMI) Kemess Underground gold-copper-silver property.

“The drill holes are very widely separated and may confirm the interpreted widespread mineral zones,” Copper North added. The company holds a 100% option on the approximately 20,000-hectare property.

In the Yukon, meanwhile, the flagship Carmacks copper project advances through the final stages of a PEA study. The company plans to improve on a 2014 PEA by factoring in gold and silver recovery.

Copper North prepares to drill Thor as Carmacks PEA approaches

August 4th, 2016

by Greg Klein | August 4, 2016

At first, it might seem like a diversion prior to imminent news of a larger scale. Copper North Mining TSXV:COL has resumed work on its Thor project in north-central British Columbia. At the same time the company’s putting the finishing touches on an updated PEA for its Carmacks project in southwestern Yukon. But president/CEO Harlan Meade sounds excited about both copper-gold projects.

Copper North searches north-central B.C. for
another deposit while advancing its Yukon project.

“We’ll start drilling Thor towards the end of the month,” he tells ResourceClips.com. “We’ll drill two or three holes in Thor West and a couple of holes in areas 2 and 3 in the Thor East part of the property. In the interim, we’re doing a lot of detailed geological mapping and sampling. Quite frankly, we’ve been pleasantly surprised … getting into the field, you can see they’re pretty exciting-looking rocks once you understand what’s going on.”

The project’s goal is porphyry copper-gold mineralization some 20 kilometres south of the mined-out Kemess South open pit, now within AuRico Metals’ (TSX:AMI) Kemess Underground gold-copper-silver property.

Copper North holds a 100% option on Thor. A road and power line pass through the 16,000-hectare property.

Out of an historic program of six holes totalling 692 metres on Thor East’s area 3, one interval returned 0.12% copper and 0.04 grams per tonne gold over 60 metres. Since then Copper North conducted extensive geophysics but market conditions postponed further drilling until this month. “The targets are big and we’re going to test our geological interpretation of what’s going on,” Meade says. “These are big targets, we can drill widespread holes and if we’re right about it and the holes come in, raising money for Thor won’t be an issue.”

In this market you need to be in the lower 10th-percentile cost curve. The only way we could achieve that was to add on gold and silver recovery. That’s a game changer.—Harlan Meade,
president/CEO of
Copper North Mining

The Carmacks report, originally scheduled for May, will replace a 2014 PEA. “The earlier study focused on heap-leaching the oxide copper deposit, but in my view that would put the project in the middle of a cost curve,” Meade explains.

“In this market you need to be in the lower 10th-percentile cost curve. The only way we could achieve that was to add on gold and silver recovery. That’s a game changer. We’ve done a lot of re-engineering, moved completely away from heap leaching to agitated tank leaching, which is a lot more efficient and gives us higher recoveries and very rapid leach times. A lot of the operational issues and environmental concerns have been largely mitigated now because everything’s contained. Our view is that we’re on track to be Canada’s next copper mine.”

The road-accessible Carmacks sits 11 kilometres from the grid, 190 kilometres north of Whitehorse and 400 kilometres from the year-round port of Skagway, Alaska.

Copper North also holds an historic copper resource at its Redstone property in the Northwest Territories’ Nahanni district.

Geoscience B.C. puts extensive resource knowledge into the public domain

It’s probably one of the biggest geophysical surveys underway anywhere. Pilots now have three magnetometer-equipped Cessnas criss-crossing an especially rugged 24,000-square-kilometre expanse of west-central British Columbia on tight, 250-metre linespacing. This is Search Phase II, part of an even bigger project that will make “a generational contribution to better understand the area’s geology and mineral potential,” says Bruce Madu, VP of minerals and mining for Geoscience B.C. But the results will hardly be limited to industry. The non-profit’s mission is to access “earth science for everyone.”

Data of this quality rarely finds its way to junior explorers, let alone prospectors. But proprietary software makes it available to anyone with an internet connection. Besides mineral opportunities, practical advantages include land use planning for regional districts, local communities and First Nations.

The grid extends from Fort Fraser to Smithers, building on two previous surveys. Last year’s Phase I flew over neighbouring terrain between Terrace, Kitimat and Smithers. The 2013 TREK program covered an area bounded by Vanderhoof, Fraser Lake and Quesnel, conducting sampling and mapping, as well as airborne mag. The three surveys combined will cover 55,500 square kilometres, about the size of Nova Scotia.

TREK’s inspiration came from the Blackwater discovery, now New Gold’s (TSX:NGD) proposed open pit mine with reserves of 8.2 million ounces gold and 61 million ounces silver. Yet “the surrounding geology is poorly understood,” Madu says.

The Phase II flyover includes another proposed mine, Pacific Booker Minerals’ (TSXV:PBM) Morrison copper-gold project, as well as Thompson Creek Metals’ (TSX:TCM) majority-held Endako molybdenum mine and the former Bell-Granisle copper-gold mines. The survey just bypasses Imperial Metals’ (TSX:III) 50%-held Huckleberry copper mine.

Low prices put Endako on care and maintenance, with Huckleberry slated to follow this summer. But Geoscience B.C. helped extend the latter mine’s life by about two years, Madu says. “We flew some geophysics, the company participated and ended up drilling new ore. A couple of hundred jobs were given a couple more years.”

The region “clearly has substantial mineral potential,” Madu points out. “Even more importantly it has excellent infrastructure, lots of road networks, there’s rail in the area and hydro nearby, so it can be quite a cost-effective place to discover and develop a mine.”

Having just reconnoitred with the Search Phase II crew, Madu waxes enthusiastically about the staff, the three Cessna Super Caravans especially suited for this survey’s challenges, the ultra-sensitive magnetometers and the preliminary data. “It excites me—the quality is superb.”

Phase II comprises one of 13 projects scheduled for this year, with a budget totalling $2.5 million. “They cover all sorts of perspectives,” Madu says. “We’ll be active in the Sheep Creek, Barkerville and Cassiar gold camps, the Toodoggone region, we’ve got a mapping crew south of Terrace working on last year’s geophysics, we’ll be east of the Penticton gold camp around the Boundary area. We have chemistry projects re-analyzing almost 5,000 archive samples from southeastern British Columbia as well as the Atlin area. And we’ve got a lot of value-added projects on the go this year, taking existing data and putting together a more complete picture combining geophysics, geochemistry and geology, which I think is a big advantage for the industry’s future, being able to have these super-sized data sets.”

Not limited to mineral exploration, Geoscience B.C. also conducts surveys related to areas such as oil and gas, geothermal energy and groundwater.

In addition to fundamental baseline data creation, we do a lot of innovative research as well.—Bruce Madu,
VP of minerals and
mining for Geoscience B.C.

“On the minerals side, during our 11 years of operation we surveyed a large portion of the province with geophysics, we re-analyzed almost the entire suite of geochemical samples for the province, we provided a lot of innovative research in glacial tills and tree-top sampling, we funded new geochemical methods using water in the field as well as capturing gases and sampling organic materials. So in addition to fundamental baseline data creation, we do a lot of innovative research as well.”

Next year’s plans call for Search Phase III extending northeast to the Quesnel copper belt and covering a region that hosts Imperial’s Mount Polley copper-gold-silver mine, the auriferous turf of Barkerville Gold Mines TSXV:BGM, Thompson Creek’s Mount Milligan copper-gold operation and AuRico Metals’ (TSX:AMI) gold-copper-silver deposits at Kemess.

Looking further ahead, Madu sees the organization “looking at the mining cycle instead of just exploration to see what we can do to help the development or efficiency of mining. We might look at research into subjects like water, tailings and metallurgy, for example.”

The group was founded in 2005 when the province put up money as an inducement to industry contributions. A lot of those contributions come from preferred rates or volunteer work supporting a small staff. Regional trusts have also contributed. Last May the province forked over $5 million.

The results of all that go online, available to everyone. Geoscience B.C.’s Earth Science Viewer opens with a satellite image of the province. Users can zoom in on a particular area, load a layer of data from the selections to the left, then overlay additional data. New info comes online as survey results are processed. Mineral tenures are updated daily, with links to the government’s database of claimholders.

“Viewers can put the tie-dyed geophysical charts on top of the geology layer to see how they agree or don’t agree,” says Madu. “I think that’s quite a powerful prospecting tool because one thing we want to do is challenge assumptions. If the geology and geophysics are telling different stories, we want people to research that and explore it.”

A planned upgrade, possibly within a year, will make the viewer three-dimensional, “something like Google Earth where you can tip it on its side and fly around valleys a bit,” he adds.

With a wealth of practical info for industry and communities alike, the viewer “puts the power of information into the hands of people who can use it.”
