Geophysics show potential kimberlite expansion on Margaret Lake Diamonds/Arctic Star Exploration’s Lac de Gras JV

August 29th, 2017

by Greg Klein | August 29, 2017

Borrowing techniques that proved successful at Kennady North, Margaret Lake Diamonds TSXV:DIA and Arctic Star Exploration TSXV:ADD announced geophysical results that potentially expand their Diagras property’s known kimberlites. The partners hold 60% and 40% respectively of the joint venture in the Northwest Territories’ diamond-rich Lac de Gras region, where Margaret Lake acts as operator.

Last spring’s ground program of magnetics, gravity and electromagnetics targeted known kimberlites as well as “unresolved targets generated from public domain data,” the companies stated. Similar techniques have helped Kennady Diamonds TSXV:KDI further its understanding of the Kennady North property’s Kelvin and Faraday kimberlites.

Results dating to 2005 on Diagras’ Jack Pine kimberlite identified a north-south axis extending more than 500 metres, with about four to five hectares at surface. But recent work north of Jack Pine shows a possible new discovery that’s been named Sequoia. Although verification would call for more drilling, the new findings indicate an anomaly that doubles the geophysical footprint, potentially making this “the largest kimberlite complex in the Lac de Gras field,” according to the partners.

Geophysics around Diagras’ Black Spruce kimberlite show anomalous gravity lows up to about 200 metres south and east of a magnetic low and its corresponding diamondiferous drill results by a previous operator. Again, drilling will be necessary to confirm the presence of additional kimberlite.

The partners also reported other geophysical signatures that might indicate additional kimberlite in and around other known kimberlites on the 18,699-hectare property. Further geophysical evaluations are planned for next spring, along with a drill program.

In addition to its Diagras interest, Margaret Lake holds its namesake Margaret Lake project adjacent to Kennady North. In July, Arctic Star announced plans to acquire the Timantti project in Finland, where due diligence has confirmed the presence of micro-diamonds. Arctic Star also holds the CAP rare earths and rare metals prospect in east-central British Columbia. Early this month the company announced discovery of a carbonatite-syenite complex, an extremely rare occurrence potentially associated with “a plethora of commodities” and “the dominant source for niobium and rare earth elements,” the company stated.

Late last month Arctic Star offered a private placement up to $1.25 million.

New assays on old core reveal more diamonds on Arctic Star Exploration’s new Finnish acquisition

July 26th, 2017

by Greg Klein | July 26, 2017

Just weeks after announcing plans to take on a diamond project in Finland, Arctic Star Exploration TSXV:ADD has found further encouragement by reanalyzing previous work. Recent assays on 48.65 kilograms of historically extracted split core showed 111 microdiamonds. The results represent approximately 52.7 metres of core from the Timantti property’s White Wolf kimberlite.

New assays on old core reveal more diamonds on Arctic Star Exploration’s new Finnish acquisition

A due diligence program reported earlier this month confirmed 58 microdiamonds from an 18.9-kilogram White Wolf sample.

With most of the world’s diamond-bearing kimberlites showing an exponential relationship between small and large stones, the company plans to gather enough caustic fusion samples to evaluate the property’s diamond size distribution. Following ground geophysics, Arctic Star hopes to drill Timantti for additional samples, delineating the kimberlites’ size and shape.

Looking at an entirely different range of commodities, the company last week sent a drill crew to the Cap project in east-central British Columbia’s Rocky Mountain Rare Metal Belt. Tantalum, niobium and rare earths are among the targets on the 2,825-hectare property. In 2010 sampling results included 0.14% Nb2O5, 3,191 ppm zirconium and 547 ppm total rare earth elements. More sampling the following year brought grades including 0.27% Nb2O5 and 773 ppm TREE, while two historic, non-43-101 samples showed 0.13% and 0.1% TREE.

Arctic Star also holds a 40% interest in the Northwest Territories’ Diagras diamond project, where JV partner Margaret Lake Diamonds TSXV:DIA conducted a short geophysical program last May.

Arctic Star sees new diamond frontier in Finland

July 12th, 2017

by Greg Klein | July 12, 2017

A plan that so far has been a year in the making would have Arctic Star Exploration TSXV:ADD shift its diamond exploration focus from northern Canada to northern Finland. The Timantti (Finnish for “diamond”) project would begin with exploration rights over 243 hectares of kimberlites, with an additional 95,700 hectares of land to come under an exploration reservation permit for which the company has applied.

Arctic Star sees new diamond frontier in Finland

Small bulk samples dating to 2005 have revealed diamonds, while a more recent due diligence program confirmed 58 small stones in an 18.9-kilogram sample from the project’s White Wolf kimberlite.

The Wolf kimberlites lie on the Fennoscandian Shield, which also hosts the major diamond mines Lomonosov and Grib in Russia’s Arkhangelsk region.

Because kimberlites tend to occur in clusters, the Wolf kimberlites could indicate a more extensive group, according to Roy Spencer, who discovered the Wolf kimberlites. Data in the public domain shows a “cloud” of kimberlite indicator minerals across an approximately 80-kilometre-wide area roughly centred on the Wolf kimberlites, the company added. “The exploration reservation will allow Arctic Star to explore the entire region,” Spencer said.

A diamond exploration veteran with De Beers and other companies, Spencer “was largely responsible for the discovery of the world-class Grib kimberlite,” Arctic Star added. Spencer joins the company as a director.

On closing the acquisition, Arctic Star plans magnetic, gravity and EM surveys prior to drilling and a subsequent bulk sample on the road-accessible property, as well as regional airborne surveys.

Ranking fifth globally in the annual Fraser Institute survey of overall mining investment attractiveness, Finland boasts arctic infrastructure in relative profusion to northern Canada.

The deal would involve Arctic Star taking over Foriet Oy, a Finnish company that would become a wholly owned subsidiary, for 14.5 million shares at a deemed price of $0.20.

Arctic Star also welcomed Scott Eldridge’s appointment to the board. A co-founder and president/CEO of Euroscandic International Group, which provides accounting and investment banking services to resource companies, he has raised over $500 million in equity and debt for mining-related projects around the world.

Last May Arctic Star announced a brief geophysical program at the Diagras diamond project in the Northwest Territories, with work expected to finish mid-month. The company has a 40% stake in the JV, with Margaret Lake Diamonds TSXV:DIA holding the rest and acting as project operator.

Margaret Lake, Arctic Star begin geophysical search for NWT diamonds

May 9th, 2017

Modern geophysics and a new approach come to a property with diamondiferous kimberlites in the Northwest Territories’ prolific Lac de Gras region, as Margaret Lake Diamonds TSXV:DIA and Arctic Star Exploration TSXV:ADD start work on their Diagras JV. Expected to finish in mid-May, the program consists of ground gravity, magnetics and Ohm Mapper EM.

Margaret Lake, Arctic Star begin geophysical search for NWT diamonds

Margaret Lake and Arctic Star hold a 60% and 40% stake respectively, with Margaret Lake acting as project operator.

The companies hope to find non-magnetic evidence that was missed in the 1990s when De Beers flew airborne surveys that identified the property’s magnetic kimberlites.

Diagras hosts 13 known kimberlites, most of them diamondiferous, according to historic data. The property’s Jack Pine kimberlite shows “multiple phases with different geophysical responses,” the JV stated. “It is hoped that our planned surveys will reveal similar geology around the other pipes. There is also a good chance to find new kimberlites using these new ground geophysical techniques.”

In November the JV attributed those techniques to Kennady Diamonds’ (TSXV:KDI) progress at Kennady North, Lac de Gras’ most advanced exploration project.

Results of the Diagras program will be considered for follow-up drilling.

In January Arctic Star applied for a drill permit for its 100%-held CAP niobium-tantalum-REE property in north-central British Columbia. The company raised over $1.47 million in private placements that closed late last year.

Arctic Star looks to B.C. for rare metals and rare earths

January 17th, 2017

A previously acquired property gets new attention as Arctic Star Exploration TSXV:ADD applies for a drill permit to search for niobium, tantalum and rare earth elements in central British Columbia.

Arctic Star looks to B.C. for rare metals and rare earths

Field work during 2010 on the 2,825-hectare CAP project found 481 to 981 parts per million niobium, 1,125 to 3,191 ppm zirconium, over 100 ppm lanthanum, over 100 ppm cerium and over 50 ppm neodymium. Two historic, non-43-101 samples returned strongly anomalous results of 0.13% and 0.1% rare earth elements, the company stated.

A circular magnetic anomaly of about three to five kilometres’ diameter could indicate a carbonatite or similar intrusion at depth, Arctic Star added. “Carbonatite-related deposits are a major host for rare metals, such as niobium and tantalum, and rare earth elements.”

Located about 80 kilometres from Prince George, CAP can be reached by logging roads during the summer and helicopter year-round.

In December the company closed a second tranche of financings totalling $1.47 million, including $300,000 of flow-through earmarked for CAP.

In November Arctic Star announced a JV with Margaret Lake Diamonds TSXV:DIA on their newly compiled Diagras property in the Northwest Territories’ diamondiferous Lac de Gras region.

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.

Looking to Lac de Gras

World diamond production drops but Canadians compete to make up the shortfall

by Greg Klein

An almost 4% increase in global diamond production by value last year coincided with an almost 4% drop in volume. Numbers released August 25 by the Kimberley Process Certification Scheme indicate higher prices kept revenue growing despite lower output. But, should December’s optimistic forecasts hold, demand will call for new sources. Among the most promising locations is Canada, which the Kimberley Process says held its third place spot for global production by value even as Russia pushed Botswana into second place. In fact Canada owes its status to just one region of the Northwest Territories, Lac de Gras, which hosts three current mines, a soon-to-be fourth and an encouraging exploration play.

The region’s most recent entry is Zimtu Capital TSXV:ZC, which on August 25 announced exploration had begun on the Munn Lake project held by the company and a staking partner. Despite about $5.7 million of work between 1996 and 2007 that found two diamondiferous kimberlites, the 14,000-hectare property has yet to undergo modern exploration.

World diamond production drops but Canadians compete to make up the shortfall

Of four kimberlites under its focus, Kennady Diamonds plans a
2015 maiden resource for Kelvin, further infill drilling for Faraday
1 and 2, and exploration at MZ.

Yet a previous 581-kilogram sample from the project’s Yuryi kimberlite showed 226 diamonds, among them 62 macro-diamonds above 0.5 millimetres in diameter. A 42-kilo sample from the Munn Lake kimberlite yielded two macros and 12 micro-diamonds. Over 2,500 samples revealed at least five distinct kimberlite indicator mineral (KIM) trains lining the property.

Zimtu now has a crew sampling KIMs to validate historic sampling and “provide additional insight into the diamondiferous potential of each area.”

Earlier this month Arctic Star Exploration TSXV:ADD announced plans to explore its 54,000-hectare T-Rex property in Lac de Gras. Historic work found over a dozen kimberlites, most of them diamondiferous, the company stated. Historic, non-43-101 results of a 436-kilo bulk sample from the Jack Pine kimberlite reported 572 micro-diamonds.

Another 299 micro-diamonds turned up in 360 kilos of Jack Pine kimberlite drilled in 2005, according to 43-101-compliant results.

Last June Arctic Star reported an update from North Arrow Minerals TSXV:NAR on Redemption, their Lac de Gras joint venture. Initial interpretation of ground geophysics indicates a number of targets for a potential 2016 winter drill program, Arctic Star stated. Its partner also has the property’s surficial geology under analysis to better define and interpret the region’s South Coppermine KIM train.

With about 97,220 hectares of Lac de Gras turf, Canterra Minerals TSXV:CTM said in June it’s identified several areas “that warrant further detailed exploration, including drilling,” along with other areas that could undergo till sampling and geophysics.

Last month Margaret Lake Diamonds TSXV:DIA announced an agreement, subject to TSXV approval, to acquire the remaining 40% interest in the Margaret Lake property, giving the company sole ownership. The company anticipates a winter drill program to test targets identified by last year’s airborne gravity survey. The 19,716-hectare property lies contiguous to the north and west of Kennady Diamonds’ (TSXV:KDI) Kennady North project, the region’s most advanced project other than the Gahcho Kué mine-to-be, which Kennady surrounds on three sides.

With four kimberlites under assessment at the 61,000-hectare property, Kennady reported results of a 443-tonne bulk sample from the Kelvin pipe on August 26. Of 16,247 diamonds recovered from four zones of Kelvin’s “more diluted” southeast lobe, 35 weighed over one carat. The zones averaged 2.02 carats per tonne for diamonds larger than 0.85 millimetres.

The lab described the five largest as follows:

  • 4.22-carat white/colourless, transparent macle with no inclusions

  • 3.95-carat brown, transparent aggregate with inclusions

  • 2.79-carat light brown, transparent aggregate with minor inclusions

  • 2.63-carat white/colourless, transparent octahedral with inclusions

  • 2.59-carat white/colourless, transparent dodecahedron with no inclusions

The project’s winter agenda calls for another bulk sample from Kelvin’s north lobe, where a 19-tonne mini-bulk sample last year averaged 2.59 carats per tonne. Kennady has Kelvin slated for a maiden resource by year-end. The company also has exploration drilling underway at the project’s MZ kimberlite and further infill drilling planned for the Faraday 1 and 2 pipes.

Kennady closed a $4-million private placement earlier this month.

 

In operation or under development: Canada’s diamond mines

Canada’s in the forefront of countries trying to make up the diamond supply shortfall, with new mines coming online as others face depletion. Besides the NWT’s three operations and De Beers’ Victor mine in Ontario, two others are in development.

Of the three Lac de Gras mines, Dominion Diamond’s (TSX:DDC) majority-held Ekati has about five years left to its life expectancy, although development of the Jay deposit could potentially add another 11 years.

Diavik, a Rio Tinto NYE:RIO/Dominion 60/40 JV, would last to 2023 with the addition of a fourth pipe.

De Beers’ Snap Lake could last to 2028, although with declining output. In March the global giant said an amended water licence might be necessary to avert a much earlier shutdown. In June the Mackenzie Valley Land and Water Board recommended the NWT government approve the application.

Ontario’s only diamond mine, De Beers’ Victor, faces depletion in 2018. The company hopes to postpone its doom by developing the Tango kimberlite, a smaller, lower-grade deposit seven kilometres northwest.

World diamond production drops but Canadians compete to make up the shortfall

On schedule for H2 2016 production, Gahcho Kué would
become “the world’s largest and richest new diamond mine,”
according to Mountain Province.

Now building Quebec’s first diamond mine, Stornoway Diamond TSX:SWY has operations scheduled to begin at Renard late next year and commercial production slated for Q2 2017. Although potential resource expansion continues, the company estimates Renard would supply 1.6 million carats annually for 11 years, providing about 2% of global supply.

A fourth Lac de Gras operation, destined to become “the world’s largest and richest new diamond mine,” remains on track for H2 2016 production. Mountain Province Diamonds TSX:MPV and joint venture partner De Beers expect Gahcho Kué to produce an annual average 4.5 million carats over a dozen years.

In Saskatchewan’s Fort à la Corne region, Shore Gold’s (TSX:SGF) majority-held Star-Orion South underwent a spring drill program to update the Orion South kimberlite’s resource. Although the project reached feasibility in 2011 and passed a federal environmental review in December, Shore now plans a revised feasibility to reduce capex.

In addition to regions around existing and future mines, Nunavut and Saskatchewan’s Pikoo region also draw significant diamond exploration.

With a decade of diamond demand outgrowing supply, Canada’s a target for new sources

by Greg Klein

Next Page 1 | 2

Diamonds: Global supply and demand

Miners of other commodities might welcome half of the diamond dilemma. Forecasts see continued market growth for another decade. But production will taper off. That’s the 10-year prognosis from Bain & Company and the Antwerp World Diamond Centre. Meanwhile another report from the NWT and Nunavut Chamber of Mines addresses the need to maintain production in the Northwest Territories, the world’s third-largest source of diamonds by value and home to a busy exploration scene.

The December 9 Bain study, which generally agrees with a September report from De Beers, expects an average 4% to 5% compound annual growth in rough diamond demand to 2024 driven largely by India, the U.S. and especially China. Supply growth, on the other hand, should lag behind at 3.5% to 4% up to 2019, then fall to somewhere between 1.5% and 2% for another five years.

With a decade of diamond demand outgrowing supply, Canada’s a target for new sources

The world’s largest source of new production would be Gahcho Kué, the De Beers/Mountain Province Diamonds TSX:MPV joint venture slated for 2016 production in the NWT’s Lac de Gras region. The mine’s expected to produce between five and six million carats annually to 2020.

Bain forecasts Lukoil’s Grib mine in Russia at four to 4.5 million carats a year when it begins operation in 2016. After that would come the Karpinsky-1 pipe at ALROSA’s Lomonosov project in Russia, expected to yield about three million carats annually after reaching commercial production in 2015. Stornoway Diamond’s (TSX:SWY) Renard project in Quebec, slated for 2016 commercial production, should be good for another 1.5 million carats a year. Looking farther ahead, Rio Tinto’s (NYSE:RIO) Bunder mine in India is projected to yield another three million carats annually on reaching full production in 2020 or 2021.

“Other new mines under development are relatively small; each is projected to produce one million or fewer carats annually,” the report states.

“Because it takes seven to 10 years to develop a mine, even if major new deposits were discovered within the next few years, there would not be enough time to bring them to full production by the end of the forecast period,” the study adds.

Diamond supply: The Canadian outlook

The supply/demand imbalance notwithstanding, jewelry retailers show increasing eagerness to trace diamonds to ethical sources, Bain points out.

Among those sources is Canada, renowned for high-quality, conflict-free stones. Diamond mining now takes place in Ontario and the NWT, with Quebec expected to join soon and Saskatchewan another possible contender. Output from just three mines in Lac de Gras ranks the NWT region third globally for diamond production by value.

Of those three, Dominion Diamond’s (TSX:DDC) majority-held Ekati is projected to run out of ore in 2019, according to the NWT and Nunavut Chamber of Mines. The chamber gives the Dominion/Rio Diavik operation a life expectancy to 2024 and De Beers’ Snap Lake until 2028.

Rio has since announced plans to bring Diavik’s A-21 deposit online. Yet the chamber maintains A-21’s expected to maintain current production, not extend mine life.

Ekati’s best chance for a stay of execution is the Jay project, “the largest diamondiferous resource in North America,” according to Dominion, and a potential extension of 10 or more years to the Ekati operation. Should environmental approval arrive by the end of 2015, Dominion hopes to begin operations by 2019.

Diamond exploration: The juniors move in

Not surprisingly, it’s up to the juniors to meet growing demand. Since Canadian diamonds are found in kimberlites and kimberlites tend to come in clusters, most exploration takes place near known deposits—with the hope that nearby kimberlites will also contain diamonds.

The hottest hotbed of activity is the NWT, especially around Gahcho Kué. Kennady Diamonds TSXV:KDI holds turf on three sides of the project. Last month the company mobilized for more exploration and delineation drilling on Kelvin, one of the Kennady North project’s four diamond-bearing kimberlites. Diamond recovery results are expected by year-end from two more mini-bulk samples.

Another Gahcho Kué neighbour, Prima Diamond TSXV:PMD holds the 42,000-hectare Godspeed Lake project immediately south of the mine-to-be. Forty kilometres northwest of Gahcho Kué and 35 kilometres east of Snap Lake, Prima holds the 14,000-hectare Munn Lake project. A 581-kilogram sample from one Munn Lake kimberlite gave up 226 diamonds while a 42-kilogram sample from another revealed 14 diamonds. Prima also optioned the Orion diamond property, 2,275 hectares in Quebec’s Otish Corridor, north of Stornoway’s upcoming operation.

Kennady, Margaret Lake update Lac de Gras diamond projects

September 16th, 2014

by Greg Klein | September 16, 2014

The most advanced of the juniors in the Northwest Territories’ diamond-rich Lac de Gras region, Kennady Diamonds TSXV:KDI announced a $5-million private placement September 16, one day after releasing a progress report for its Kennady North project. Approximately $3.5 million of the placement has already been subscribed to by Bottin International Investments, Kennady’s largest shareholder.

The project lies adjacently north and west, and to the southwest, of Gahcho Kué, scheduled by De Beers and Mountain Province Diamonds TSX:MPV to start producing diamonds in the second half of 2016.

Kennady, Margaret Lake update Lac de Gras diamond projects

Four known kimberlites and about four exploration targets
have drilling scheduled this season at Kennady North.

Kennady reported a delineation hole that added another 215 metres (not true width) to the project’s Kelvin kimberlite, surpassing last July’s 183-metre intercept that the company had called the project’s longest to date. The new result started at a shallower-than-expected downhole depth of 157.5 metres and remains open at 373 metres in depth. A “fan” of three holes at different angles has delineated Kelvin “well beyond the current geological model,” said CEO Patrick Evans. “Preparations are now underway for the drilling of a fan of three further delineation holes to continue tracking Kelvin to the north.”

That will follow four other delineation holes, two drilling to the east and two to the west, with the three-hole fan in the pipe’s centre.

Of the other recently reported holes, one showed 32.15 metres of kimberlite starting at 215.7 metres. Two holes at different angles from the same collar found 161.5 metres starting at 127 metres in depth, and 164 metres starting at 152.25 metres.

When diamonds are found in Canada, they’re in kimberlites. But few kimberlites actually host the gems. Earlier this month, however, staff logging Kelvin drill core noticed a “high-quality” 0.94-carat diamond that Kennady described as “white/colourless, transparent, octahedral, distorted, twin with etched trigons” and without inclusions. The stone came from a depth of about 75 metres.

Expected in Q4 are lab results for the 25-tonne mini-bulk sample extracted from Kelvin last spring. The summer program has pulled out another 22.5 tonnes of Kelvin kimberlite. In addition to delineation and mini-bulk sampling, the season’s agenda calls for exploration drilling at Kelvin.

Kennady North’s Faraday, MZ and Doyle kimberlites also have drilling scheduled this season, as do approximately four new exploration targets. Early last month Kennady lauded Faraday results of 5.1 carats per tonne as among Canada’s highest-ever sample grades.

Also on September 15 Margaret Lake Diamonds TSXV:DIA reported from two nearby properties. Margaret Lake lies immediately north of Kennady North, with a thin southward extension that partly divides its neighbour. West of Margaret Lake, the eponymous company optioned 49% of Canterra Minerals’ (TSXV:CTM) Marlin property.

Airborne gradiometry and magnetics have been completed on Margaret Lake and part of Marlin. The latter property will also get “a digital terrain model together with detailed bathymetry using WorldView2 high-resolution satellite imagery,” the company stated.

On reviewing Margaret Lake’s historic ground geophysics, the company identified three targets in the property’s narrow southern extension. As for the recent survey, preliminary analysis “shows a gravity response that relates to the two historic ground gravity targets,” the company added. “These three targets exhibit characteristics similar to known kimberlite bodies and will be subject to further evaluation.”

Besides the Gahcho Kué mine-in-progress, Lac de Gras hosts three of Canada’s four diamond producers, Diavik (60% Rio Tinto NYE:RIO/40% Dominion Diamond TSX:DDC), Ekati (80% Dominion) and De Beers’ Snap Lake.

Other companies exploring Lac de Gras include Canterra, North Arrow Minerals TSXV:NAR, Arctic Star Exploration TSXV:ADD and Prima Diamond TSXV:PMD.

Diamond fever hits the NWT

September 10th, 2014

Prima Diamond lands prime locations to pursue the Northwest Territories’ gems

Reprinted by permission of Market One Media

Next Page 1 | 2

Diamond deposits, in the words of one senior geologist, are like pigeons. Where you find one, you’re likely to find an entire flock.

That’s the guiding logic behind a new wave of diamond mine development and claim staking in the Slave Craton in the Northwest Territories. The NWT already serves as host to some of the world’s richest diamond mines, starting with Ekati and Diavik, followed by Snap Lake, all in the central corridor of the Slave Craton.

A new wave of exploration pursues gems in the Northwest Territories

Gahcho Kué diamond mine under construction, projected to open in 2016.

Next to follow is the Gahcho Kué diamond project southeast of the prolific Ekati and Diavik diamond mines. When it begins production in 2016, Gahcho Kué is reputed to become one of the largest and richest new diamond mines in the world. This $700-million project has a combined probable mineral reserve estimated at 55.5 million contained carats. De Beers Canada owns 51% of Gahcho Kué and is the operator of the proposed mine. Mountain Province Diamonds TSX:MPV, which discovered the Gahcho Kué diamond resource, owns 49%.

Next to Gahcho Kué is the Kennady North project with four confirmed diamond pipes. Two of the pipes returned diamond sample grades two to three times greater per tonne than Gahcho Kué, as reported by the company.

Circling in the vicinity of Gahcho Kué are projects led by successful veterans of the original 1990s Canadian diamond rush: Randy Turner, CEO of Canterra Minerals TSXV:CTM; Buddy Doyle, director and vice-president of exploration with Margaret Lake Diamonds TSXV:DIA; and Patrick Evans, president and CEO of Kennady Diamonds TSXV:KDI.

Turner discovered the Snap Lake diamond mine. Evans led SouthernEra Resources when it performed much of the foundational geological research in the Slave Craton area two decades ago. Doyle led a team involved in the Diavik discovery. He also took part in exploration at one of two properties in the area acquired this year by Prima Diamond TSXV:PMD.

In mineral exploration, “closeology”—proximity to a mineral resource—can mean a lot, or a little. For a gold deposit, it’s usually irrelevant. For diamonds it’s a whole different story.

“The best place to seek a high-grade diamond deposit is close to one that has already been identified,” explains Roger Morton, professor emeritus in the Department of Earth and Atmospheric Sciences at the University of Alberta.

Prima Diamond—a comparative newcomer to the diamond exploration business—won the staking rush to acquire the highly prized Munn Lake property north of Gahcho Kué. Its Godspeed Lake property is immediately adjacent to Gahcho Kué on the south and has barely been explored.

“Diamonds tend to be like pigeons. They go around in flocks,” Morton says, pointing to Gahcho Kué as the spark for surging interest in the area. “In the Munn Lake area, for example, there is a kimberlite which is the host rock for diamonds.”

Interest in the southern Slave Craton took another jump this summer when tonnage estimates in Kennady’s Kelvin-Faraday kimberlite corridor increased by 30% to 10 million tonnes.

With its two properties, Prima is well positioned to take advantage of the excitement.
