Pistol Bay signs LOI on Confederation Lake property, expands airborne geophysics

May 5th, 2017

by Greg Klein | May 5, 2017

Update: On May 8 Pistol Bay announced a further expansion of the airborne VTEM Plus survey, from 1,128 to 2,100 line-kilometres, covering a 40-kilometre length of the Confederation Lake greenstone belt.

An upcoming geophysical program has been extended to fly a potential land acquisition under consideration by Pistol Bay Mining TSXV:PST. The company announced a letter of intent on the 496-hectare Copperlode property, about four kilometres along strike from Pistol Bay’s Arrow zone in Ontario’s Confederation Lake greenstone belt. Having already assembled the area’s largest land package, the company plans region-wide, state-of-the-art exploration over neglected but VMS-rich ground.

Copperlode would bring Pistol Bay two more historic, non-43-101 estimates:

  • D zone: 32,600 tonnes averaging 7.58% zinc and 0.26% copper

  • E zone: 145,000 tonnes averaging 8.28% zinc, 1.02% copper and 24 g/t silver

Additionally, some historic, non-43-101 drill intercepts include:

  • B zone: 2.5% zinc and 1.68% copper over 6.3 metres

  • C zone: 0.21% zinc and 6.02% copper over 1.5 metres

  • Hornet zone: 7.56% zinc and 0.08% copper over 6.6 metres
  • 4.07% zinc and 1.13% copper over 5.03 metres

Hornet remains open at depth and along strike.

On finishing the region-wide airborne VTEM Plus campaign Pistol Bay may acquire an initial 65% option on Copperlode from Frontline Gold TSXV:FGC, which holds an option on the claims from another vendor. Pistol Bay would pay Frontline $26,000 and issue 450,000 shares over two years and spend $150,000 over three years. Another $50,000 and 300,000 shares would boost Pistol Bay’s stake to 80%.

Pistol Bay’s current Confederation Lake portfolio consists of 9,450 hectares with a number of historic estimates, including the 2007 Arrow resource on which the company began a 43-101 update last month.

Also last month, the company closed a $336,000 private placement that followed a $548,436 placement in March. April brought more money with $750,000 from a Rio Tinto NYSE:RIO subsidiary as part of its 100% option on Pistol Bay’s uranium properties in Saskatchewan’s Athabasca Basin.

The Rio deal

March 29th, 2017

Cashed-up Pistol Bay Mining consolidates and updates Confederation Lake

by Greg Klein

From a Rio Tinto NYSE:RIO subsidiary comes money for an unprecedented campaign in Ontario’s Confederation Lake greenstone belt. That’s where Pistol Bay Mining TSXV:PST has region-wide exploration with modern methods about to begin on a VMS-rich area that’s previously seen piecemeal, unco-ordinated work with old school technology. President/CEO Charles Desjardins sees plenty of promise in his portfolio’s historic resources. But he also likes the blue sky possibility of a new discovery.

Funding the campaign will be $750,000 from Rio, along with this month’s private placement of $548,436. Proceeds go to the largest land package in Confederation Lake, a region of base metals deposits that Desjardins considers to be clamouring for up-to-date exploration.

Rio’s portion comes as the giant exercises more of its 100% option on the junior’s C4, C5 and C6 uranium properties in Saskatchewan’s Athabasca Basin. The deal originally called for $5 million by the end of 2019 and a 5% net profit interest to acquire the final 25%. Now Rio pays the $750,000 along with either $1.5 million by 2017 year-end, $2 million by 2018 year-end or $2.25 million by 2019 year-end, plus the 5% NPI.

“That’s less money than the original option, but I can create so much value with it now,” says Desjardins. “And I’m doing it without dilution.”

First item on the agenda—and long overdue, Desjardins believes—will be helicopter-borne VTEM Max, penetrating to depths of 500 to 700 metres. “There have been major Canadian discoveries over the last decade with this kind of geophysics,” he points out. “But very little of this belt, less than 5% of it, has been explored beyond 200 metres. There’s only one zone examined to 300 metres and that was with downhole geophysics by Noranda.”

He expects the first of three airborne campaigns to begin within four weeks. While Pistol Bay’s package comprises 9,450 hectares, “we’re going to fly this whole belt,” he adds. “I’m looking for something bigger, something that hasn’t been found.”

As for the deposits that have been found, they’re overdue for upgrading to 43-101 status. First priority is the polymetallic Arrow deposit, which has a 2007 estimate that Pistol Bay considers historic and non-43-101:

3% zinc-equivalent cutoff

  • indicated: 2.07 million tonnes averaging 5.92% zinc, 0.75% copper, 21.1 g/t silver and 0.58 g/t gold

  • inferred: 120,552 tonnes averaging 2.6% zinc, 0.56% copper, 18.6 g/t silver and 0.4 g/t gold

5% zinc-equivalent cutoff

  • indicated: 1.76 million tonnes averaging 6.75% zinc, 0.79% copper, 22.3 g/t silver and 0.61 g/t gold

  • inferred: 51,631 tonnes averaging 3.86% zinc, 0.79% copper, 23.9 g/t silver and 0.58 g/t gold

10% zinc-equivalent cutoff

  • indicated: 633,000 tonnes averaging 14.3% zinc, 1.11% copper, 31.7 g/t silver and 0.85 g/t gold

Desjardins expects about a month to redo the resource, incorporating another 20 holes.

About eight kilometres west of Arrow, the Fredart zone, also known as Copperlode A, has an historic, non-43-101 estimate showing 385,000 tonnes averaging 1.56% copper and 33.6 g/t silver.

Roughly 24 kilometres farther west, the Dixie property’s historic, non-43-101 estimate comes to 136,000 tonnes averaging 14% zinc.

Estimates for other zones, all with historic, non-43-101 caveats, include:

  • Dixie 3: 83,000 tonnes averaging 10% zinc and 1% copper

  • Diamond Willow: 270,000 tonnes averaging 4% zinc

There have been major Canadian discoveries over the last decade with this kind of geophysics. But very little of this belt, less than 5% of it, has been explored beyond 200 metres.—Charles Desjardins, president/CEO of Pistol Bay Mining

Past work has left an extensive legacy of other data too. Historic records for the recently optioned Joy North property show intriguing electromagnetic and geochemical anomalies. Pistol Bay’s team has been poring over details of about 850 Confederation Lake holes sunk between 1962 and 2007. A Noranda database of rock chemical analysis, meanwhile, could offer insight into the belt’s VMS mineralizing process and help define zinc-copper targets.

Along with February’s Joy North option, Pistol Bay’s acquisitions continue with the Lucky 7 and Moth properties picked up this month. Now yellow metal shows its Confederation Lake potential with one 2016 grab sample assaying 13.84 g/t gold and 3.21% copper.

As for drilling, the already-permitted Joy North might be first, depending on the review of historic info. Eight other areas have permitting underway. The rigs will take part in Pistol Bay’s threefold near-term agenda: the Arrow resource, the VTEM Max and a drill program, all of which should fuel a steady news flow. “We’ve got lots of work coming up and, thanks to the Rio payment, money to do it with no dilution,” says Desjardins.

Apart from growing the existing deposits, he clearly believes in the potential for a new discovery. “The opportunity here is in consolidating the belt and exploring the whole thing at depth, which hasn’t been done. There’s lots of blue sky at Confederation Lake.”

Pistol Bay Mining adds new property to Confederation Lake portfolio

February 16th, 2017

by Greg Klein | February 16, 2017

Pistol Bay Mining TSXV:PST hopes to unlock one of the puzzles of western Ontario’s Confederation Lake greenstone belt with its 100% option on the Joy North property. The 64-hectare claim lies contiguous with the company’s previously acquired Joy group of claims, which include five mineralized VMS zones. Pistol Bay’s Dixie zone is located about 11 kilometres east of Joy North.

Pistol Bay Mining adds new property to Confederation Lake portfolio

The new property covers a 1,000-metre-long conductive zone where a geochem survey found anomalous zinc, copper and gold. The conductor’s stronger areas also showed stronger magnetic responses.

In 1970 a single 48-metre hole found metavolcanic rocks with the intense alteration associated with volcanogenic massive sulphide deposits. The hole also revealed calc-silicate rocks “suggesting the property may lie at the same stratigraphic horizon as the Dixie zone,” Pistol Bay stated.

The previously acquired Joy group includes the Diamond Willow zone, with an historic, non-43-101 estimate of 270,000 tonnes averaging 4% zinc.

Past drilling highlights from the other four zones have included:

  • Joy Zone: 3.1% copper and 0.2% zinc over 5.7 metres
  • 4.01% copper and 0.17% zinc over 3.35 metres

  • Creek Zone: 2.33% copper and 0.27% zinc over 0.95 metres

  • South Zone: 0.28% copper and 17.17% zinc over 0.6 metres
  • 0.17% copper and 8.36% zinc over 0.25 metres

  • Caravelle Zone: 0.13% copper and 21.6% zinc over 0.25 metres
  • 0.22% copper and 4.44% zinc over 1.1 metres

The new acquisition “includes one of the very few electromagnetic anomalies in the prolifically mineralized Confederation Lake greenstone belt that has not been satisfactorily explained by diamond drilling,” commented CEO Charles Desjardins. The geochemical anomalies also “make it a prime exploration target,” he added.

Subject to approvals, Joy North’s price tag comes to a total of one million shares and $40,500 over four years. A 2% NSR applies, half of which may be bought back for $500,000 and the other half for $1.5 million. Pistol Bay must also drill at least two holes totalling 600 metres. The company intends to drill the project this year.

Last month Pistol Bay updated plans for a regional, multi-disciplinary approach to its Confederation Lake portfolio, which hosts properties that were previously explored by different companies in an inconsistent manner.

In Saskatchewan’s Athabasca Basin, Pistol Bay also holds the C4, C5 and C6 uranium properties, currently being drilled by a Rio Tinto NYSE:RIO subsidiary earning a 100% interest.

Two days before the Joy North announcement, the company appointed geologist Jody Dahrouge to its advisory board.

Jody Dahrouge

As president of Dahrouge Geological Consulting, he and his staff have worked with a broad range of exploration and mining companies. Until 2007, Dahrouge served as president/COO of Fission Energy, a predecessor of Fission Uranium TSX:FCU. While there he played a key role in the acquisition of Waterbury Lake and Patterson Lake South, both of which yielded significant discoveries. Dahrouge has also served as a director and VP of exploration for Commerce Resources TSXV:CCE since 2000.

“We are excited to be able to benefit from the knowledge and expertise of Mr. Dahrouge and look forward to working with him,” said Pistol Bay CEO Charles Desjardins.

Last month the company outlined plans for a regional and multi-disciplinary exploration approach to its Confederation Lake portfolio, the largest land package in the western Ontario greenstone belt. Pistol Bay expects to file a 43-101 technical report on Confederation Lake’s Arrow zone by mid-March.

In Saskatchewan’s Athabasca Basin, the company holds the C4, C5 and C6 uranium properties, now being drilled by a Rio Tinto NYSE:RIO subsidiary as it advances towards its 100% option.

Rio continues 100% option on Pistol Bay Mining’s Athabasca Basin uranium project

January 24th, 2017

by Greg Klein | January 24, 2017

Having resumed drilling, a Rio Tinto NYSE:RIO subsidiary advances towards a 100% interest in Pistol Bay Mining’s (TSXV:PST) C4, C5 and C6 uranium properties in Saskatchewan’s Athabasca Basin. Rio Tinto Exploration Canada has so far earned 75% of the properties and stated its intention to exercise the full option. That would bring Pistol Bay $5 million by the end of 2019 and a 5% net profits interest.

Rio continues 100% option on Pistol Bay Mining’s Athabasca Basin uranium project

Located in a prolific area, C4, C5 and C6 adjoin Wheeler River, a JV of Denison Mines TSX:DML, Cameco Corp TSX:CCO and JCU (Canada) Exploration that hosts two exceptionally high-grade deposits. The Phoenix zone holds an indicated resource of 70.2 million pounds averaging 19.13% U3O8, the world’s highest-grade undeveloped uranium deposit.

Wheeler’s Gryphon zone shows an inferred 43 million pounds averaging 2.3%. C4, C5 and C6 are located about halfway between Cameco’s majority-held McArthur River, the world’s largest high-grade uranium mine, and Key Lake, the world’s largest uranium mill.

Rio plans four to six holes totalling about 2,600 metres on C5 beginning this month. Past work at C5 has included 12 holes totalling 6,104 metres, along with gravity and DC resistivity surveys.

Five kilometres of rough roads link the three properties to the all-weather route connecting McArthur River with Key Lake.

Last week Pistol Bay updated plans for its properties in Ontario’s Confederation Lake greenstone belt, where the company holds the area’s largest property package. Pistol Bay plans to bring modern geophysics and a region-wide approach to a district where previous companies have explored individual properties at different times.

Late last month the company closed a private placement first tranche totalling $201,850.

Diamonds—2016 glitter in review

December 22nd, 2016

by Greg Klein | December 22, 2016

The stones began the year still mired in their 2015 slump, in which rough prices reportedly fell 15%. The two biggest players, representing nearly two-thirds of global production, didn’t exactly agree on strategy. De Beers cut production and lowered prices while Alrosa initially boosted production, held prices stable and stockpiled some output. By April De Beers raised prices and Alrosa lowered production. The following month had De Beers talking about a “fragile recovery.”

Diamonds—2016 glitter in review

Sales records for polished got pulverized, though. In May Sotheby’s raked in $32 million for the 15.38-carat Unique Pink in a jewelry sale that totalled a world record $175.1 million. The next day Christie’s scooped up $58.25 million for the 14.62-carat Oppenheimer Blue, “a new record price for any gemstone and per carat.”

Rough rode roughshod over records, too. The week before Sotheby’s and Christie’s big sales, Lucara Diamond TSX:LUC got $63.11 million for its fresh-from-the-mine 812.77-carat Constellation. High expectations led to disappointment in late June, however, when the company rejected a $61-million offer for its 1,109-carat Lesedi La Rona rough stone, the second-biggest diamond ever found. Lucara wanted at least $70 million.

As for Canadian diamond mining, it thrived.

A 100-million-carat production milestone brought celebrations to Diavik, the Northwest Territories JV of Rio Tinto NYSE:RIO and Dominion Diamond TSX:DDC. In July Dominion finally decided to add the Jay pipe and its 78.6 million carats to the company’s majority-held Ekati mine.

The year brought new mines to Canada too. Gahcho Kué, the world’s largest new diamond producer in 13 years, was officially opened in September by partners De Beers and Mountain Province Diamonds TSX:MPV. October saw Stornoway Diamond TSX:SWY do the same at Renard, Quebec’s first diamond mine. It reached commercial production just days before Christmas.

Looking at potential mines-to-be, Peregrine Diamonds TSX:PGD took its Chidliak project on Baffin Island to PEA in July. In Saskatchewan’s Fort à la Corne region, meanwhile, Shore Gold TSX:SGF continued working on a feasibility update for its majority-held Star-Orion South project. Back in the NWT, Kennady Diamonds TSXV:KDI completed its maiden resource in December.

The company’s Kennady North project sits in the same Lac de Gras region hosting Ekati, Diavik and Gahcho Kué. November marked the 25th anniversary of the Chuck Fipke/Stewart Blusson Ekati discovery that triggered the world’s biggest staking rush, brought diamond mining to Canada and helped transform the diamond industry.

In December the vertically integrated company Almod Diamonds announced plans to broaden the NWT diamond industry, the backbone of the territorial economy, by re-opening a Yellowknife cutting and polishing facility.

A few days after that announcement, the allure of diamonds played out differently in an Atlanta department store. Eighty-six-year-old Doris Payne, a determined, unrepentant and often unsuccessful diamond thief, wracked up another arrest. She’s been stealing stones for over sixty years.

Pistol Bay Mining brings regional exploration to Ontario’s VMS-rich Confederation Lake

by Greg Klein

During the doom and gloom of mid-2015 Charles Desjardins saw a hopeful sign in zinc. A search for prospective sources led the president of Pistol Bay Mining TSXV:PST to the volcanogenic massive sulphide deposits of western Ontario’s Confederation Lake greenstone belt. There he found different operators left what he considered a mixed legacy—work that was very impressive but carried out in a rather unco-ordinated manner. Now, with a commodity that’s justified his optimism and a portfolio that’s poised to be the belt’s largest, his company’s launching an ambitious new program to take a region-wide approach to Confederation Lake.

“Even though there’s been a lot of money spent in that region, there really hasn’t been a lot of continuity in exploration programs,” says Desjardins. “For example we found 8,000 rock geochemistry samples that Noranda did. In today’s terms that’s about $300,000 worth of work just for the analysis, never mind actually acquiring all those samples. We don’t know if Noranda did anything with this, it might have been right when they were getting out of there. But it showed us some obvious things, including a couple of new, big, big targets and extensions of known targets.”

Pistol Bay Mining brings regional exploration to VMS-rich Confederation Lake

That’s just part of the inspiration for a two-tiered program to begin in January. Drilling would start with about six holes and a few thousand metres, he says. “Beyond that, the plan is to do a regional airborne survey with new technology that can see VMS-style mineralization at 600 to 700 metres. When you look at Flin Flon and Snow Lake, geophysics there found two major deposits at the 500-metre level.”

Confederation Lake characterizes the tendency of VMS deposits to appear in clusters, Desjardins points out. He attributes the region’s largest mine, South Bay, for around 354 million pounds of zinc, 57.6 million pounds of copper and 3.74 million ounces of silver produced between 1972 and 1981. Grades averaged about 11.06% zinc, 1.8% copper and 72.7 g/t silver.

Pending exchange approval for a four-year option on AurCrest Gold’s (TSXV:AGO) regional holdings, Pistol Bay’s turf comprises 7,050 hectares along a 43-kilometre stretch of the 60-kilometre-long belt. The projects include four historic deposits.

Already under a four-year option is a contiguous group of properties named Dixie 17, 18, 19 and 20 that’s been consolidated into a single project. Dixie comes with a 1992 historic, non-43-101 “mineral inventory” from Noranda estimating 150,000 short tons with an average 14% zinc.

Some eight kilometres southeast, the Dixie 3 property, formerly called Snake Falls, hosts another historic, non-43-101 Noranda estimate, this one 91,000 short tons averaging 1% copper and 10% zinc.

Roughly 20 kilometres northeast sits the Arrow zone, one of the acquisitions waiting approval. Arrow comes with a 2007 resource compiled by AurCrest predecessor Tribute Minerals that Pistol Bay isn’t treating as 43-101 and intends to re-do. Using three cutoff grades, the estimate showed:

3% zinc-equivalent cutoff

  • indicated: 2.07 million tonnes averaging 5.92% zinc, 0.75% copper, 21.1 g/t silver and 0.58 g/t gold

  • inferred: 120,552 tonnes averaging 2.6% zinc, 0.56% copper, 18.6 g/t silver and 0.4 g/t gold

5% zinc-equivalent cutoff

  • indicated: 1.76 million tonnes averaging 6.75% zinc, 0.79% copper, 22.3 g/t silver and 0.61 g/t gold

  • inferred: 51,631 tonnes averaging 3.86% zinc, 0.79% copper, 23.9 g/t silver and 0.58 g/t gold

10% zinc-equivalent cutoff

  • indicated: 633,000 tonnes averaging 14.3% zinc, 1.11% copper, 31.7 g/t silver and 0.85 g/t gold

That acquisition includes the contiguous Copperlode A or Fredart zone, with its historic, non-43-101 estimate of 425,000 tonnes averaging 1.56% copper and 33.6 g/t silver.

Even though there’s been a lot of money spent in that region, there really hasn’t been a lot of continuity in exploration programs.—Charles Desjardins,
president of Pistol Bay Mining

Obviously these deposits cry out for 43-101 treatment. Pistol Bay intends to begin with Arrow, the most recent resource but with another 16 holes to consider. Desjardins hopes to have that done within six months.

He points to assays that followed historic estimates on the other deposits, like 7.34% zinc and 1.4% copper over 9.5 metres, and another 15.44% zinc and 0.43% copper over 4.3 metres at Dixie. Intriguing zinc-copper intercepts also came from the Joy-Caravelle area, part of the AurCrest package. Historic sampling at Copperlode A found molybdenum grading up to 1.46%.

Then there’s the 8,000 geochemistry samples left by Noranda. Additionally, Pistol Bay has MPH Consulting at work on an extensive review of previous geophysics. Add to that the new airborne and drilling to begin in January and Desjardins looks forward to a wealth of data with considerable potential waiting to be unlocked.

There’s strong community support too, he adds. “One First Nation invested I think about $600,000 in AurCrest,” he says.

In Saskatchewan’s uranium-prolific Athabasca Basin, Pistol Bay JVs with a Rio Tinto NYSE:RIO subsidiary on the C-5 project. Having earned 75% of its option already, Rio has stated its intention to acquire the full 100% by the end of 2019. That would bring Pistol Bay $5 million and a 5% net profit interest.

The company expects to soon close the first tranche of a private placement offered up to $810,000. Other financings would follow, as Confederation Lake’s regional exploration continues in stages.

“We already have significant deposits that might be developed with one central mill,” Desjardins says. “But we’ll be looking for an elephant too.”

NRG Metals completes due diligence on Argentinian lithium properties

November 21st, 2016

by Greg Klein | November 21, 2016

Among the companies active in South America’s Lithium Triangle, NRG Metals TSXV:NGZ has finished due diligence on two properties that would comprise the Carachi Pampa project in northwestern Argentina. Totalling 6,387 hectares, the contiguous properties sit in an area hosting geological features common to other lithium-rich salars in the region, the company stated on November 18. “The lithium target is a paleo salar (basin) at depth that has the potential to host lithium-enriched brines.”

NRG Metals completes due diligence on Argentinian lithium properties

NRG sees potential for lithium-enriched brines
in the Lithium Triangle’s Carachi Pampa project.

Located 40 kilometres from the town of Antofagasta de la Sierra at about 3,000 metres in elevation, the properties have winter access, a paved road 10 kilometres away and nearby services.

NRG has retained experienced lithium explorers Rojas and Associates and Sergio Lopez and Associates to review the project, with Rojas to complete a 43-101 technical report.

The properties are subject to different four-year purchase agreements, according to an LOI announced September 21. With all dollar figures in U.S. currency, one property calls for $120,000 on signing a definitive agreement, $200,000 in each of three annual payments and $600,000 at the end of the fourth year. A 1% NSR applies, which NRG may buy back for $1 million.

The other project would cost $160,000 on signing, $100,000 in two annual payments, $250,000 in year three and $625,000 in year four. Again, the company may buy back the 1% NSR for $1 million.

NRG offered a private placement up to C$1 million. Additionally, the company has negotiations underway on other properties.

In October NRG announced a management team for its Argentinian subsidiary, NRG Metals Argentina S.A. Executive director James Duff has written several 43-101 reports for Argentinian projects and served as COO of McEwen Mining TSX:MUX acquisition Minera Andes and president of South American operations for Coeur Mining NYSE:CDE.

Non-executive director José Gustavo de Castro is a chemical engineer with extensive experience in the evaluation and development of Argentinian lithium projects including the continent’s largest lithium producer, FMC Corp’s Hombre Muerto operation.

Manager of business development and corporate relations José Luis Martin’s 35-year career includes senior positions with Galaxy Lithium S.A. and Rio Tinto’s (NYSE:RIO) Argentinian projects.

Director Jorge Vargas specializes in property, mining and business law in Argentina.

Also last month NRG announced plans to spin out other assets to concentrate on lithium. The portfolio currently includes the LAB graphite project in Quebec and the Groete gold-copper resource in Guyana.

Arctic Star/Margaret Lake Diamonds form JV, follow Kennady’s approach to NWT kimberlites

November 15th, 2016

by Greg Klein | November 15, 2016

A new joint venture brings together Arctic Star Exploration TSXV:ADD and Margaret Lake Diamonds TSXV:DIA in the Northwest Territories’ Lac de Gras region. Finding inspiration in Kennady Diamonds’ (TSXV:KDI) success at Kennady North, the partners plan a similar approach to their newly compiled property.

By posting an approximately $200,000 bond with the NWT government, Margaret Lake has earned a 60% interest in 23 claims totalling 18,699 hectares comprising the Diagras property, the JV announced November 15. Hosting 13 known diamondiferous kimberlites, the claims were formerly part of Arctic Star’s 54,000-hectare T-Rex property.

Arctic Star/Margaret Lake Diamonds form JV, follow Kennady’s approach to NWT kimberlites

The bond accompanies an application to extend the Diagras claims to August 2017.

“We identified the claims we wanted to joint venture based on our evaluation of historic data and we specifically focused on those claims that have known kimberlitic occurrences,” said Margaret Lake president/CEO Paul Brockington. His company will act as project operator.

The JV intends to follow Kennady’s modus operandi. The property’s Kelvin and Faraday kimberlites were dropped by De Beers and Mountain Province Diamonds TSX:MPV as they advanced Gahcho Kué, recently opened as the world’s largest new diamond mine in 13 years.

De Beers considered Kelvin and Faraday low grade, based on their lack of prominent magnetic anomalies, according to the Arctic/Margaret JV. Mountain Province then spun out Kennady to explore the pipes. That company “applied ground geophysics, gravity and Ohm mapper EM, which revealed extensions to these kimberlites that were not revealed in the magnetics,” the Diagras partners stated. “Subsequent drilling and bulk sampling has shown that these non-magnetic phases of the kimberlites have superior diamond grades to the magnetic phases and significantly increase the tonnage potential.”

Looking at some nearby deposits, the JV states that certain kimberlites at the Rio Tinto NYSE:RIO/Dominion Diamond TSX:DDC Diavik mine and the high-grade portions of Peregrine Diamonds’ (TSX:PGD) majority-held DO-27 kimberlite “are non-magnetic, proof that a magnetic-only approach in the Lac de Gras field could miss significant diamondiferous kimberlite bodies.”

The JV plans to follow Kennady’s surveying approach at Diagras. Most of the property’s kimberlites have had only one to three drill holes into their magnetic anomalies.

The partners also see potential in “two untested geophysical targets and several diamond indicator mineral anomalies that are not clearly sourced from the known pipes.” Ground geophysics are scheduled to begin next spring.
