Boreal Metals Corp. (TSX-V:BMX, Frankfurt 03E) is focused on discovering silver, zinc, copper, gold and nickel deposits in Sweden and Norway. The company aims to find and develop economic mineral deposits in known/ historical mining districts, in areas that have seen limited modern exploration.
Based in Vancouver, Canada with an office in Sweden, Boreal currently has two projects on the go: Gumsberg in Sweden and Burfjord in Norway. EMX Royalty Corp. (NYSE:EMX), a global prospect generator, holds royalties on both properties, along with a 9.4% equity interest.
Gumsberg, an 18,300-hectare land package with five exploration licenses, was mined from the 13th century through to the 1900s, with an astounding 30 historic mines on the property including Östra Silvberg – the largest silver mine in Sweden from 1250 to 1590.
The project is in good company, located within the Bergslagen mining district between the past-producing Falun and Saxberget mines, and the active Garpenberg (Boliden) and Zinkgruvan (Lundin) mines.
Burfjord is located 32 km west of the Kåfjord copper mines, the first major industrial enterprise north of the Arctic Circle. The road-accessible project is 40 km from Alta, where there is a regional airport, and 7.5 km from tidewater.
Patricio Varas, Executive Chairman and CEO, has been working in mining for 30+ years. He was a founder of Western Potash, raising over $240 million, and was instrumental in the discovery of the Santo Domingo Sur deposit in Chile, now being developed by Capstone Mining. Varas was also the project manager during discovery at Diavik, a diamond mine operated by Rio Tinto in the Canadian Northwest Territories.
Director Eric Jensen, who is also General Exploration Manager for EMX, has over 20 years experience as a mine geologist, mine-site exploration geologist, and grassroots exploration geologist.
Dan MacNeil, Vice President of Exploration, is a precious and base metals specialist with over 19 years of experience with continental-scale project generation to in-mine resource expansion, in a wide variety of geological settings throughout the Americas and Eastern Europe.
Boreal has also brought in former Boliden management which is very unique for an exploration company. Thomas Söderqvist, Director, and Rodney Allen, Technical Advisor, were both senior management at the largest mining company in the region.
Mining-friendly Sweden & Norway
For mining companies and explorers, Sweden and Norway are extremely desirable countries to work in. Sweden has nearly 100 companies with active exploration permits, and around 6,000 people directly employed in the industry. A 2011 national strategy for mineral exploration has resulted in more funding for mapping and gathering data on minerals.
Political stability, a solid legal system based on penal and civil law, and highly developed infrastructure are important pluses for mining. Sweden has 12,000 kilometers of rail track (85% electrified) and 69 ports including Goteborg, Falkenbergs Terminal, Ahus and Stockholm.
Another little-known fact about Sweden is the low cost of power. Commercial electricity contracts are in the order of 4 to 5 cents a kilowatt-hour, which is 20% cheaper than the normal cost of power in Europe. That’s important for mining because it allows miners to lower their cut-off grades in order to process more ore economically.
The corporate tax rate is a competitive 22.5%. There are no state royalties or other assessments, making the effective tax rate for mining around 23% in Sweden.
Mining is governed through the Swedish Minerals Act; mining laws have been in place since the 1300s according to the Geological Survey of Finland. Exploration rights are valid for three years and can be extended for up to 15. Once a concession is granted it’s good for 25 years, with a 10-year extension possible if work is performed on a regular basis.
A key advantage of exploring in Sweden is the short permitting process. Where permitting can take years/decades in other jurisdictions, in Sweden it can be a matter of months, if all the i’s are dotted and t’s crossed. The environmental laws are well-defined.
Like Sweden, Norway boasts low energy costs, and a low corporate tax in the mid-20-percent range.
The Nordic nation has a predictable and efficient administration, no withholding tax on royalty payments, no government royalty, and an experienced workforce. There are several smelters, deep-water ports, and an excellent national rail system. Most roads are paved and accessible year-round.
The oil economy has been a boon to Norway. However, a shift in economic focus has seen the minerals industry come roaring back to the country, giving way to a renaissance of mineral exploration and mining.
In June Boreal Metals (TSX-V:BMX, Frankfurt 03E) signed a deal with major Scandinavian mining company Boliden, to advance Boreal’s 100%-owned Burfjord (pronounced “burf yord”) copper-gold project in northern Norway.
The agreement means that Boliden, a base and precious metals miner with six active mines in Europe and five smelters across Norway, Sweden and Finland, will have the opportunity to earn a 51% stake (Boreal would be the operator) in the project by spending US$6 million in exploration over the next four years.
If that happens, the two companies will form a joint venture, and Boliden will get a crack at earning another 29% by funding and delivering an NI 43-101-compliant feasibility study, pushing its ownership to 80%. Boreal retains a 20% stake.
EMX will keep its 3% net smelter return (NSR) royalty on the project.
“The option agreement with Boliden, a leading mining and smelting company in the region, represents a significant step forward in the advancement of Boreal’s exploration project portfolio,” Patricio Varas, Chairman and CEO, said in the June 10 news release. “Collaboration with Boliden will maximize the potential for a significant copper-gold discovery at Burfjord and will facilitate value creation.”
Boreal’s excellent technical team explains Boliden’s confidence in tapping the junior, whose $6.8 million market cap is a tiny fraction of Boliden’s CAD$10.2 billion market value, to lead the exploration program for the first four years of the earn-in agreement, and possibly the remainder of the earn-in period.
The Burfjord property is comprised of six exploration licenses totaling 5,500 hectares. Mineralization belongs to the Iron Oxide Copper Gold (IOCG) deposit clan; this portion of northern Fennoscandia is a key IOCG province globally. Copper was mined in the Burfjord area during the 19th century, with over 30 historic mines and prospects developed along the flanks of a prominent 4 x 6-kilometer anticline.
IOGC deposits are among the most valuable concentrations of copper, gold, and uranium ores. These orebodies, ranging from around 10 million tonnes of contained ore to 4 billion tonnes or more, have grades of 0.2 to 5% copper, and gold from 0.1 to >3 grams per tonne. Their tremendous size, relatively high grades and simple metallurgy give IOGC deposits the potential for making extremely profitable mines.
High-profile examples include BHP’s Olympic Dam complex in Australia, and the Candelaria undeveloped copper-gold deposit in Chile.
Burfjord is characterized by broad arrays of copper, gold and cobalt-bearing veins dominated by iron-oxide and iron-carbonate-rich mineral assemblages reminiscent of Iron Oxide Copper Gold mineral deposits (IOCGs). The large associated alteration system at Burfjord and widespread copper mineralization support the project’s potential to host a large copper deposit.
Varas noted having significant successes with IOCG-type projects when he headed Far West Mining. That company formed a strategic alliance with BHP, the world’s largest miner, exploring and drilling properties in Australia, Sweden, Argentina, Chile and Canada. Varas’ team carries that experience with them as they aim to solve the mysteries underlying Burfjord.
“We know these deposits really well, we know what we’re looking for, the tools you need to find them, the kinds of alteration systems you need to have, the type of mineralization – of course this deposit has all of that in spades,” he said.
The project hosts gold and cobalt-bearing high-grade copper veins which occur in broad zones of disseminated style copper mineralization covering a 4 x 6-kilometer window of copper-prospective geology (Figure 1).
Many of the rocks in the anticline are intensely hydrothermally altered and contain sulfide mineralization. High-grade copper-gold veins at Burfjord that were historically mined at cutoff grades of 3-5% copper are surrounded by envelopes of stockwork veins or disseminations of copper mineralization extending tens to hundreds of meters laterally into the host rocks.
The company believes this mineralization has economic potential and represents an attractive bulk-tonnage exploration drilling target.
Copper-bearing veins are dominated by ferroan carbonate, sodium-rich minerals, and iron-oxide minerals (magnetite and hematite), but also contain the economically important minerals chalcopyrite, bornite and chalcocite in addition to cobalt-rich pyrite as generally coarse-grained (often 0.5 centimeter to multi-cm scale) disseminations in the veins.
A key point: only limited exploration has taken place in the modern era. Historical drilling produced intercepts including 7m @ 3.6% Cu (Cedars Gruva prospect).
Taking another look at Figure 1, the property hosts a number of copper occurrences (the red dots) near surface, spread over a large area. These areas are best described as surface pits, mined up to 300 years ago by artisanal miners. It is quite incredible that, until now, no company has tried to consolidate all of these historical workings into a mineable resource.
This is the challenge presented to Boreal and its earn-in partner, Boliden.
Recently Boreal went into these shallow pits for samples, and mapped them.
In March, 2019 the company announced compelling drill results from Burfjord, including an intercept of 32 meters averaging 0.56% copper and 0.26 g/t gold (including 3.46m of 4.31% Cu and 2.22 g/t Au) at shallow depths below a group of historic mine workings. This and other drill-defined zones of copper and gold mineralization are slated for immediate follow-up.
“The fact that it was over 30 meters wide gives you a sense there is bulk tonnage potential for a larger deposit,” Varas said.
Indeed what really gets the CEO’s blood pumping, is the potential for what lies beneath. And remember, this is an experienced geologist who has worked these types of IOGC deposits before. He knows what to look for, and what to do when he finds it.
“The occurrences you see are expressions of a larger system. The deposit for all I know could be buried and so the idea here is to go and find perhaps one large deposit within all of these areas,” he explained. “[The occurrences] give you a sense of the hydrothermal system, meaning the liquids that carried the mineralization were very pregnant with copper. What you want to do is find the right traps, the right environment, where you can concentrate a significant amount of it together and that’s what you’re going to mine.”
Of course, it’s early days to be talking about mining, but the prospect of a large mineralized system right at Boliden’s doorstep must have been a factor in persuading the Scandinavian miner and mineral processor to take a $6-million chance on Boreal Metals.
“In fact the Norway smelter, they get material from as far as Ireland, so for them it’s very natural, it’s strategic to look for deposits that might eventually feed that smelter, so doing exploration in Norway makes a lot of sense for them,” said Varas, adding,
“When you sample around, the amount of copper is quite impressive and I think that’s what impressed Boliden. Having had some success in finding what I think is a very significant deposit in Santo Domingo Sur in Chile certainly helps. I think they have some confidence we can look at these systems and have the right methodology to look for another big deposit.”
The next steps for Boreal involve gathering information, to come up with drill targets to present to its new partner.
“You need all of this data, you need the mapping so you can map the structural regime, you need the airborne mag [survey] to find concentrations of magnetic bodies, and you need to see what the distribution of the alteration is, because we know there’s a hydrothermal system there,” says Varas.
Geophysical surveys are certainly a priority, to identify the structures that transported the hydrothermal fluids upward to infill just about every crack in the rocks near surface with mineralization. Varas noted that magnetic and gravity surveys will likely both be required. That’s because iron oxides host magnetite and hematite. Magnetite, being magnetic, shows up in a mag survey, but non-magnetic hematite does not.
“The magnetic bodies don’t necessarily host the copper mineralization, often they occur in non-magnetic bodies, the hematite, but gravity [surveys] would show you that quite well,” he said.
Boreal’s Gumsberg VMS project in southern Sweden is an 18,300-hectare land package with five exploration licenses. The property was mined from the 13th century through to the 1900s, with an astounding 30 historic mines on the property including Östra Silvberg – the largest silver mine in Sweden from 1250 to 1590. Twenty-one holes were drilled between 1939 and 1958.
The project is in good company, located within the Bergslagen mining district between the past-producing Falun and Saxberget mines, and the active Garpenberg and Zinkgruvan mines mentioned above.
Volcanogenic massive sulfide (VMS) deposits are sought after for mining because they usually contain a melange of base metals and sometimes precious metals including zinc, lead, copper, silver and gold. The minerals are often clustered together, making them relatively easy to extract.
The geological theory Boreal is operating under, is that the high-grade zinc-silver grades they are finding, look like re-mobilized mineralization that precipitated out of the rocks as they were pushed and pulled during volcanic activity millions of years ago.
The company is also noticing steep “chimney-like structures” at Östra Silvberg that are analogous to the orientation of the deposits found at the nearby Garbenberg mine, some of which go as far as a kilometer deep.
The most exciting aspect of this, is the possibility of finding the original VMS mineralization that could be the source of the re-mobilized deposits.
New geophysical surveys plus reconnaissance drilling and analysis of historical drill data identified fresh targets near the historical workings.
In early 2018, while drilling under the Östra Silvberg mine, Boreal drilled a hole that was so high-grade, the area demanded further investigation. The hole returned about 22% combined lead-zinc, plus well over 600 grams per tonne silver. “In terms of value it’s over $800 per tonne material, or higher,” Varas said in a 2019 Ahead of the Herd video interview.
In 2019, a 1,454-meter drill program reported high-grade silver-zinc-lead results.
At its Östra Silvberg South discovery, Hole GUM-19-03 cut mineralization between 262.25m and 270.29m downhole, returning 5.12% zinc, 2.27% lead and 93 grams per tonne silver over 8 meters.
Hole GUM-19-01 pulled up even deeper core, intersecting 1.99m of 2.28% lead, 25.52 g/t silver, 0.92% lead and 0.128 g/t gold, between 304.96 and 306.95m.
Significantly, two of the four holes drilled at Östra Silvberg South intercepted unmapped mine workings that plunge deeper than expected and further east than indicated by historical maps – suggesting that the mineralization is more extensive than previously thought.
“We are delighted to see that the new Östra Silvberg South discovery continues to return high-grade silver-zinc-lead mineralization,” said Varas, in the July 9, 2019 news release. He added: “Drilling completed to date on this zone has returned consistent intercepts from below surface to roughly 250 metres. This new discovery at Gumsberg has relatively low density of exploratory diamond drilling and remains open in all directions. We are excited for what further delineation drilling may deliver in the future.”
Boreal stands out as a company with huge exploration potential, and the company is knee-deep in mining experience. Director Jensen is a PhD geology with tons of projects under his belt, and he has country experience. He knows the Sweden portfolio back to front while with EMX, where he is the General Manager of Exploration. We also like that the board has brought on Thomas Söderqvist, who has worked for Boliden as a top executive. Söderqvist not only knows the territory (Boliden’s Garpenberg mine is close to Gumsberg) he has drilling supplier expertise. Patricio Varas, and his highly qualified team, are mining veterans who know what it takes to move projects forward both technically and financially.
At its Burfjord project in Norway, Boreal Metals is seeing a lot of “smoke” at surface for what could be a very large mineralized copper-gold system at depth, “the fire”.
We see a lot of potential in this project and are eager to see what the initial geophysical studies come up with. These old mined pits are spread out over a very large area, and there are a lot of them. There must have been an incredibly powerful driving force from below to fill so many fractures veins over such an extensive area.
The fact that Boliden Mining has not only committed to spending $6 million on exploring Burfjord over the next four years, but has entrusted Boreal Metals and its crack team of geologists to managing the $6,000,000.00 exploration program, is a tremendous vote of confidence in the junior.
We also like the fact that Boreal has a buyer for its raw ore waiting in the wings. It makes sense for Boliden to invest in a property that might in the future feed its Norway smelter. The property appears to be in a great location, with the nearby community of Alta serviced by local roads and an airport, and only 7.5 km to tidewater.
Boreal Metals already has a winner in its Gumsberg VMS project in Sweden, now the exploration company is gearing up to explore Burfjord, thanks to Boliden’s decision to fund the expenditures.
At Gumsberg, Boreal has rich base-metal content and a precious metals kicker. Usually when gold and silver prices are up, the economy isn’t doing so well and base metals prices are down. The reverse happens during economic booms. This makes a VMS mine a winner during all economic cycles. They also have scale. A junior that comes upon a VMS deposit will be the belle of the ball as far as attracting mining company suitors looking for a partner, a property, or an acquisition, since a VMS mine can produce high metal volumes for many years.
Boreal is cashed up and ready to go exploring having recently closed a $2.59m financing.
We love the Gumsberg project, especially its high silver grades. The company has only just started exploring this property with 30 historic mines including Östra Silvberg, at one time the largest silver mine in Sweden.
We expect plenty of news flow as Boreal looks for more high-grade VMS among the historic mine workings and identifies additional prospects within this 18,000-hectare land assemblage.
