Sudbury, Ont. - It's been a slow ride for Wallbridge Mining (wm-t), but one that has been picking up. With one successful spin-out, another in the making and a project near production, the explorer is ready to change gears.
"We're trying to take things in the money direction," says Warren Holmes, Wallbridge's chairman, at a dinner in early June. With that, he says the train for the Sudbury basin-based explorer is heading towards mining.
Wallbridge is looking to put its Broken Hammer copper-platinum-palladium-gold deposit into production by next year.
In late June, it finished shipping a 30,500-tonne bulk sample from its most advanced project to Xstrata's (xta-l) Strathcona mill for processing. The metallurgical recoveries, along with the results from the recently completed drill program, will be used to enhance the resource estimate and complete a feasibility study.
The project's current resource is on the Northern Rim of the Sudbury igneous complex and forms a surface zone of vein- and vein stockwork-hosted copper and platinum group elements (PGE). Broken Hammer has an inferred resource of 251,000 tonnes grading 3.80 grams per tonne of total precious metals (1.56 grams palladium, 1.62 grams platinum and 0.61 gram gold per tonne), 1.00% copper and 0.10% nickel.
The resource, prepared by Roscoe Postle Associates in 2005, used a cutoff value of $40 per tonne and the then long-term metal prices of US$800 per oz. platinum, US$180 per oz. palladium, US$400 per oz. gold, US$1.40 per lb. copper, and US$5 per lb. nickel.
However, the new resource estimate and feasibility study will use the current long-term metal prices. Wallbridge plans to launch the study once the bulk sample results are out later this summer.
The junior discovered the Broken Hammer zone as a result of an ongoing grassroots exploration program in 2004, says Wallbridge's president and CEO Alar Soever, adding the company's geologists broke several hammers in the discovery.
The discovery outcrop had been mapped previously by other guys who called it granite. Our guys were trained to break a lot more rock and look at it, says Soever, while driving several directors to view the deposit before dinner.
"They saw a few grains of chalcopyrite in the first outcrop. And then, they started peeling back moss and hammering away on the other outcrops in the area. They broke a hammer...Once they started to see the better mineralization, they got a little over excited and started banging away with their hammers and broke a couple. So, they called it the Broken Hammer deposit," he says.
The Broken Hammer property was previously part of Falconbridge's Wisner property, which Wallbridge joint ventured from the major.
Currently, the company holds 98.5% of the Broken Hammer property, while Xstrata Nickel holds a 1.5% net smelter interest.
In 2005, to finance its Minnesota properties, Wallbridge spun-out those assets into a new company called Duluth Metals (dm-t). Duluth began trading on the Toronto Stock Exchange in 2006. As part of the transaction, Wallbridge shareholders received one Duluth share for every four Wallbridge shares held. The company also got 10 million Duluth shares.
To date, Wallbridge owns 8.9% or 11.1 million Duluth shares. At the end of March 2011 these shares were worth about $24.1 million (or $2.17 per share). The company says the Duluth shares are an important part of the underlying value in Wallbridge as it provides financial stability.
From last September to January 2011, the company sold 1.1 million Duluth shares to raise a total of $3.4 million. The money went towards bulk sampling the Broken Hammer deposit, and advancing the company's other Sudbury projects.
Wallbridge had deferred the bulk sampling during the financial crisis of 2008-09 because of the collapse of metal prices, says Soever, adding that the sample, which was initiated in late 2010, should now make the company a profit. As well, confirm the grades of the resource, which contains coarse grains of platinum.
The junior can increase its current interest in Duluth from 8.9% to 15.67% by exercising its participation right in certain future equity issuances.
Duluth Metals' flagship asset is the Nokomis copper-nickel-PGE project, which is held 40% by partner Antofagasta (anto-l).
The project sits in the Duluth complex mining camp in northeastern Minnesota, and hosts a National Instrument 43-101 compliant resource of 550 million indicated tonnes of 0.639% copper, 0.200% nickel and 0.66 gram per tonne TPM (platinum, palladium and gold). It has another 274 million inferred tonnes at 0.632% copper, 0.207% nickel and 0.68 gram per tonne TPM.
Over the next three years, Antofagasta will spend US$130 million to advance the project towards a feasibility study.
In March, Duluth Metals acquired Franconia Minerals to add several nearby resources to Nokomis, with three NI 43-101 compliant resources at the Maturi, Birch Lake and Spruce Road deposits. As part of the arrangement, Antofagasta gave Duluth $30 million to keep its current equity interest, which included a $20-million placement of 7.6 million Duluth shares at $2.63.
Meanwhile, Duluth continues to wholly own interests in 310-sq.-km of the Duluth complex.
With the success of Duluth, the company is in the midst of listing its second spin-out company Miocene Metals on the TSX Venture Exchange.
Wallbridge spun-out seven of its porphyry copper-gold-molybdenum properties in southwestern British Columbia into the new company last April. The properties cover the Miocene age intrusions of the Cascade Magmatic Arc, an underexplored belt with porphyry-style mineralization.
Soever says the Miocene spin out is a way to share exploration risks without diluting Wallbridge and its shareholders from the Duluth asset. "Why would you dilute yourself out of that asset to go and do grassroots explorations, when you can go do that in a new vehicle, of which we are keeping a piece of? If it does well, we do well, our shareholders do well. There's no risk to the mother ship."
Wallbridge received 20 million Miocene shares for vending in the properties, and bought another 2 million shares in a recent private placement. However it gave about 700,000 of those shares to Paget Minerals (pgs-v) for the Salal claims. Currently, Wallbridge holds 21.3 million Miocene shares, or 66% of the company as the end of March. (It also has an 11.63% carried interest in the seven B.C. properties.)
Last May, Wallbridge shareholders received one special warrant of Miocene for every six Wallbridge shares held. Once, Miocene wraps up its initial public offering (IPO), Wallbridge shareholders could convert their special warrants into Miocene shares.
Last year, Miocene, as a private company, initiated exploration work on the properties, and this year plans to launch an aggressive drill program in mid-July. The two-phase $4-million program will be funded by using flow-through funds raised in 2010 and the net proceeds of the company's IPO, which is underway.
This year, Miocene will be testing targets along a 15-km trend of molybdenite occurrences on the Salal property and drilling its MacKenzie and Roger Creek properties.
Soever lists Broken Hammer, Duluth and Miocene Metals as the three value centres for Wallbridge shareholders.
Mining in Sudbury
"Sudbury is always known for its nickel," says company's manager of joint ventures, Joshua Bailey, adding the Sudbury basin has seen more than 125 years of mining.
"But there's significant (amounts of) precious metals in the camp and, in particular, in these footwall copper and platinum group type of deposits that we are looking for."
The company is currently looking for footwall deposits and offset dykes rich in platinum group metals because of their higher value per tonne.
However, traditionally the majors in the area, Inco and Falconbridge, focused on deposits that were rich in nickel along the contact of the Sudbury igneous complex.
But a lot has changed since the '70s as to how far one should look from the contact, says Soever, explaining the majors would drill to the contact and stop once they hit a nickel-copper zone.
"But with the prices of metals on the rise, the platinum group metals in the footwalls have become more attractive," but, adds they are smaller and harder to find.
The footwall, offset dyke and nickel-rich contact deposits are the three main types of ore found in Sudbury.
It's widely believed that the ore in Sudbury formed as a result of a 1.85-billion-year-old meteorite, notes Wallbridge in its 2010 annual report. Upon impact, the meteorite smashed and melted the local metal-rich rocks to create a 250-km diameter crater with a 3-km thick melt sheet of molten rock. Upon cooling, the heavier base and precious metals sunk to the bottom of the melt sheet and into the fractures of the underlying rocks, which created offset and footwall deposits. The melt sheet then solidified to form the Sudbury igneous complex.
The company is currently exploring the footwall deposits at Broken Hammer and the joint-venture Frost Lake project, among its other properties in the area.
In total, the explorer has 42 properties in Sudbury, spanning 730 sq. km, making it the third-largest land holder in the area, after Vale (VALE-N) and Xstrata. However, only 14 of those projects are active.
While the junior has a dozen of projects to choose from, Bailey says, it has four key stories in Sudbury. He lists them as: Broken Hammer; the joint-venture Parkin Offset project; the fairly grassroots East Range area; and the developing large North Range.
The junior is spending $5.9 million to drill about 10,000 metres this year on its areas of interest. About $2.4 million of that amount was committed by its various joint-venture partners.
Soever says the company has several partners so it could share the risks and costs of exploring early-stage projects.
"When you have a grassroots property, it's better to share the risks on the one property. When you find something, sure, you are giving away some of the upside. If you don't find anything, you spend other people's money and avoid diluting the company as a whole."
Wallbridge attracted the attention of Impala Platinum with its Parkin Offset property in 2008. The joint venture covers 9.4 km of the Parkin Offset dyke and includes the past-producing Milet mine. The mine saw a historic production of more than 157,000 tons grading 2.25 grams platinum, 2.98 grams palladium, 0.33 gram gold, 1.49% copper and 1.54% nickel.
The partners say they are reviewing last year's drill results, before drilling this year at the Milnet 1500 zone, which was discovered in 2009 and lies beneath the Milnet mine.
Impala recently paid $5 million to earn a 50% stake in the Parkin Offset property, which it can boost to 65% by funding a feasibility study.
In the East Range, where exploration is centred on copper-PGE footwall deposits, the company has its Skynner Lake and Frost Lake properties. This year, the company plans to punch 2,500 metres at Frost Lake, with Xstrata. (The company has three other joint ventures with Xstrata.) The companies will test several targets near the Amy Lake PGE zone at Frost Lake, where Wallbridge is the project's operator and has a 58% interest.
The Skynner Lake property is part of the Sudbury camp joint venture (SCJV) with Lonmin (lmi-l). The joint venture includes seven Sudbury properties, where Lonmin can earn 50% in any of the properties by outlining an indicated resource and another 15% by funding a feasibility study.
For this year, Lonmin has contributed $1 million to the $1.25-million SCJV exploration budget to explore the properties.
In the North Range, Wallbridge has 12 packages which include joint ventures with Champion Bear Resources (CBA-V), Pele Mountain Resources (GEM-V) and CaNickel Mining (CML-T) formerly Crowflight Minerals.
The properties in the North Range are situated north of the Onaping-Levack area, which hosts many producing and past-producing mines as well as Xstrata's Strathcona mill.
But the focus in that area is the Hess Offset dyke, which the company traced for more than 21 km across its own properties and its joint ventures with Champion Bear and Pele Mountain. The company says outcrop exposure is generally poor (less than 1%); however, surface mineralization has been located in various places along its length.
While Wallbridge has a lot of drilling planned this year, chairman Holmes says, completing the Miocene spin off is "extremely important" adding the company will continue to develop Broken Hammer and its other Sudbury projects.
"Our focus is this pipeline of projects. We will continue to exploit it. And see how much we can do," he says, adding the company's ride ahead should be an exciting one.
Wallbridge's shares recently closed at 22.5¢, within a 52-trading range of 14.5¢-29.5¢.
