Diamonds, Canada, And Rogue Geologists

The following article is not about global warming, but a fascinating story about a persistent, rogue geologist and the discovery of diamonds in Canada.

Behind an unmarked door in a faded business park outside Kelowna, British Columbia, in a maze of rooms crowded with desks, computers, and floor-to-ceiling shelves, Chuck Fipke sifts through 20-pound bags of dirt.

"We take samples, hey, from gravel and streambeds all over the world," Fipke says. He sieves the earth, runs it through magnetic drums and centrifuges and electromagnetic separators. Then his technicians, working with scanning electron microscopes, separate out grains and mount them on postage-stamp-sized squares of epoxy. It's painstaking work but worth the trouble. Fipke has learned to understand those grains of dirt, and that understanding has led him to diamonds.

Eighteen years ago, there was no such thing as a Canadian diamond — as far as anyone knew. Diamonds came mostly from Australia, Botswana, South Africa, Namibia, and Russia. De Beers mined 75 percent of the world's output, much of it tainted by controversial "blood diamonds," sold to fund African wars.

Today, Canada is the world's third-largest producer, by value, of rough stones. In the Northwest Territories, BHP Billiton's Ekati mine has been producing since 1998 and Rio Tinto's Diavik mine since 2003. De Beers opened its first Canadian mine, at Snap Lake, in July — a confirmation that Canada is the new center of the world.

The story behind the addition of Canada to the ranks of diamond-producing nations leads back to one man: a short, absentminded Canadian geologist named Chuck Fipke. When he discovered diamonds in Lac de Gras, Northwest Territories, in 1991, he started the largest staking rush in North America since George Carmack found gold in the Klondike a century earlier. And he's not finished: He's prospecting around the world, toting gravel samples back to his lab in British Columbia to figure out where to look for his next big strike.

In 1970, fresh out of the University of British Columbia with a degree in geology, Chuck Fipke signed on with mining company Kennecott Copper to look for gold and copper in Papua New Guinea. A helicopter would drop him off alone in the middle of a jungle, and pick him up at the end of the day. The terrain was so rough that the chopper often couldn't land — Fipke would just leap out as it hovered close to the ground. One day he turned around to face 20 locals, arrows strung. He raised his arms, slowly removed his vest, and offered it to "the one who looked like the chief." By the time the helo returned for him, Fipke was in his underpants clutching a fine array of tribal shields, bows and arrows, and fetishes. "I've got an amazing collection of stuff!" he says.

Fipke is a small man with a shaved head, a burnished tan, piercing blue eyes, and forearms like Popeye's. As a kid, his frantic start-stop mind made people think he was stupid. After getting his high school girlfriend pregnant, he agreed to marry her ... and then failed to show up for the wedding. (The couple eventually married after the baby was born.) He stutters and says "hey" in almost every sentence. He frequently loses his glasses and his keys, shows up late to appointments, and has a history of spending prodigious amounts of money in strip joints. His nicknames have included Captain Chaos and Stumpy.

After stints in the Amazon, Australia, and South Africa, Fipke opened a mineral separation laboratory in British Columbia in 1977. A year later, Superior Oil hired him to go back into the field — to look not for metals but gems.

The company already had a search method. A couple of years prior, a geologist named John Gurney, working with Superior's money at the University of Cape Town, hypothesized that certain common minerals might reliably form alongside diamonds. He used an electron microprobe to analyze geological structures called kimberlite pipes — the places you occasionally (but not often) find diamonds — and discovered that the presence of chromite, ilmenite, and high-chrome, low-calcium garnet did indeed predict a rich strike. He examined a host of pipes in South Africa that had these so-called indicator minerals and published a paper explaining his results.

Fipke heard about Gurney's work on a tour of De Beers' Finsch Mine in South Africa and quickly turned himself into an expert on indicator minerals — combining what he understood of Gurney's work with results coming out of Russian labs and his own skills with field sampling. Superior had worked with Fipke before, back in his gold mining days, so by the time the company wanted someone to go look for kimberlite pipes northwest of Fort Collins, Colorado, Fipke was the best choice. He found half a dozen, but like 98 percent of the kimberlite formations in the world, they didn't contain diamonds in commercially viable quantities.

But Fipke knew that, 100 miles under those pipes, was a craton, a thick, old chunk of continental plate where diamonds form. Kimberlite pipes are created when magma bubbles up through a craton, expanding and cooling on its way up. If the craton has diamonds in it, the result is either a carrot-shaped, diamond-studded pipe reaching up to the surface or a wide, flat underground structure called a dike.

Fipke also knew that the craton underneath the pipes he had found ran all the way up the Rockies. With Superior's backing, he teamed up with a geologist and pilot named Stewart Blusson, formed Dia Met Minerals, and headed north.

By 1981, the two men were sampling the ground in Canada; they would eventually secure mining concessions on 80,000 square miles. "It was just me and Sewart and a floatplane," Fipke says. "We took all the supplies and all the samples in ourselves."

De Beers geologists, it turned out, were already there, relying on their own indicator mineral formulas. But Fipke and Blusson surmised that the indicators De Beers found had in fact been dragged far from the kimberlite pipe eons ago by a passing glacier. What they needed to do was look "upstream" for the point of origin. Fipke got a helicopter and flew back and forth over the Arctic Circle, using a magnetometer to track variations in magnetic field that would suggest kimberlite. After thousands of miles and hundreds of hours in the air, he found a promising site near Lac de Gras, a barren world of lakes and rock and muskeg a few hundred miles outside the Arctic Circle.

He'd been surveying for eight years. He hadn't found a single diamond. Superior had abandoned the diamond business. Dia Met's stock was trading at pennies a share. But based upon a few samples, Fipke estimated a diamond concentration at Lac de Gras of more than 60 carats per 100 tons — with about a quarter of the stones of good quality or better. (In kimberlite pipes that have gem-quality stones in commercial quantities, a concentration of 1 carat — 0.2 grams — per 100 tons can be profitable.) After six months of sampling, Fipke went public. It was 1991, and he had found a kimberlite pipe (buried under 30 feet of glaciated sediment) with a concentration of 68 carats per 100 tons — the first Canadian diamonds ever found. Shares of Dia Met rocketed to $70. Fipke had partnered with mining giant Broken Hill Proprietary Company (now BHP Billiton) to get the diamonds out; BHP opened the Ekati mine at Lac de Gras in 1998. Soon Dia Met's 29 percent share of the mine was worth billions. Fipke would go on to sell his chunk to BHP for $687 million, retaining 10 percent ownership in the mine, worth another $1 billion.

Today Canada's diamond business is soaring. The country's four working mines produced 17 million carats in 2007, up 23 percent from 2006. Diamonds from Canada now account for 10 percent of all diamonds by carat sold in the world. And the addition of more diamonds to the global market hasn't driven prices down. Average carat value has actually risen 15 percent, and the gems from the far north are untainted by the bad publicity that comes from an association with African wars.

Shortly before Fipke sold most of his Ekati claim to BHP Billiton, his marriage, faltering for years after so much time in the field, fell apart. At the time it was the largest divorce settlement in Canadian history. "Cost me $200 million, hey," Fipke says. "Best money I ever spent!"

Fipke now has mining projects in Morocco, Greenland, Canada, Angola, and Brazil. His laboratory bookshelves are heavy with mineral guides — and the family histories of thoroughbreds. Besides diamonds, he's now obsessed with horse racing. "It's a huge challenge, hey, and I like challenges even if they're risky," he says. "And I think I'm really going to do spectacularly well with horses." So far, so good: He has more than 50 brood mares in Ireland and Kentucky and 20 racehorses all over the world. His horse Tale of Ekati placed fifth in this year's Kentucky Derby. "I always go to the Derby with Bo Derek," he says, unlocking the door to a windowless room piled with maps and electron microscopes and computers. "She's a good rider, and she knows horses. And she's a lot of fun, hey! I'm gonna do for horse racing what I did for diamonds!"

Whether or not Fipke actually turns out to have an eye for horseflesh, his eye for the characteristics of crystals is unparalleled. He shows me rooms of glass flasks and tubes, the equipment for analyzing all those gravel samples. I peek through a microscope and see a rainbow treasure of sparkling gems: green chrome diopsides and red garnets — the low-calcium, high-chrome G-10s that mean diamonds are nearby.

Over many years in the field and the lab, Fipke has refined his understanding of this unique stew of minerals. "Everyone now knows that G-10 garnets with low calcium might lead you to diamonds, hey," Fipke says. "But how do you distinguish between a Group 1 eclogitic garnet that grew with a diamond and a Group 2 eclogitic garnet that didn't? They look the same." Custom software compares the grains' shapes and chemical compositions, analyzes them against 1,000 minerals that are intergrown with diamonds, and compares them against 10 fields of mineral groupings. If seven to 10 of the fields from one pipe overlap, Fipke says, "there's no doubt; it's full of diamonds. No one else out there can distinguish between these similar tiny particles of minerals that grow with a diamond and ones that don't."

"Look," he says, opening a folder on a table. He has thousands of photos of mineral grains magnified to the size of golf balls. Some are all sharp corners and jagged edges, some rounded. Since erosion and age wear the minerals down, "we can tell when we're getting closer to the source. If the edges are sharp, hey, we know they haven't traveled far from the pipe."

That level of geographic precision has allowed Fipke to stake more claims. He's even working in areas of Brazil where De Beers hasn't been able to turn a profit. "And Angola. Angola has the richest alluvial diamond river in the world," he says, "and there are thousands of diamond works there. But we're looking for the source pipes." Five years ago Fipke started making magnetometer survey flights over the Kwango River. Having identified 100 possible targets, he now has 40 men taking core samples 900 to 1,200 feet under the riverbed. "I'm there at the camp at least three times a year, hey, and it's much harder than in the Arctic. Your drilling equipment just gets buried in enormous piles at customs in Luanda and you can't get it. In the Northwest Territories it was cold, hey, and full of snow, but you get a good parka and you're a bug in a rug. Angola is the most inefficient place on earth!"

I start to ask another question, but Fipke has something else in mind. "I'm hungry, hey," he barks, as the door to the map room slams shut behind us. "Do you like oysters?" But we're not going anywhere: He has locked his keys in the room and has to call someone to drive in and open up his office.

We finally head into town. "Hi, Chuck!" says the hostess, leading us to the back room of a hip Asian fusion place. Around a long table sit 23 young women, all sporting stilettos and big hair. "Chuck!" they shout. We have, it seems, shown up at the bachelorette party for Fipke's granddaughter. The hostess seats us at the next table. Fipke orders four dozen oysters and a bottle of wine that has to be driven to the restaurant from some special cellar, and a young women shimmies into the booth next to Fipke. "Chuck," she says, kissing him on the cheek, "do you think you can pay for us all tonight?"

"Sure," Fipke says, beaming.

"Do you remember this?" says another woman — his daughter, it turns out, who slides in next to him, holding up a purse. "You bought it for me!"

With Fipke suddenly bankrolling the night, the girls break loose, and the restaurant staff starts hauling out the bottles of champagne. Pretty soon a couple of lasses are dancing on the tables, the oysters are slipping down, a second bottle of rare wine is being decanted, and Fipke is remixing the menu like Danny DeVito in Get Shorty.

And the tales spill forth: three week forays into the Peruvian Amazon, travels with the Kalahari Bushmen of Southern Africa, visits to the pygmies of the Ituri forest in the Congo. "I'd just leave my family and go, hey," he says. "I was really into native culture."

Somebody asks him about Brazil, and it reminds him of something important. "Caipirinhas!" he shouts out of the blue. "I want 25 caipirinhas!"

When the bill arrives, it's 3 feet long and $4,000. Fipke pays up, and we spill into the night — his daughter and granddaughter and their friends and now boyfriends, who joined us in the restaurant. On the street, Fipke suddenly leaps into the air and delivers a solid, suede loafer-clad foot to the head of a parking meter. "I fucking hate parking meters, hey!" he shouts. He jumps and kicks another one, and then erupts into a fit of giggles.

We are ushered past the velvet rope at the Cheetah Lounge, Kelowna's classiest strip joint, and Captain Chaos orders another round of caipirinhas for everyone. Three generations of Fipkes pound drinks as naked women dangle upside down from poles onstage.

The room is spinning by the time Fipke takes me aside and lays a big warm hand on my arm. "Hey," he says, "here's the thing. I learned that I did my best. I mean, I really tried my best. How many people can say that? I worked hard, and I mean really hard. I worked seven days a week from 8 am until 3 am. Every day. We drilled and drilled all winter when it was dark and the windchill was 80 below. Everyone thought I was crazy. But most people just never do their best, hey. And I did."

"Warmer is Better": Canada Reverses Global Warming Stand

"Warmer is Better": Canada Reverses Global Warming Stand

Popular summer sports like ice diving could end under a new Canadian policy of encouraging large increases in greenhouse gas emissions.

(Ottawa, Ontario) Canada's new conservative leadership has decided to not only ignore its carbon dioxide emission limits imposed by the Kyoto treaty it agreed to, but is now advocating greatly increased emissions. "Let's be honest", said Natural Resources Minister Larry Gunn, "Canadians are tired of freezing to death eleven months out of the year and having to drive to Florida just to thaw out. We use a huge amount of energy for heating, and the warmer we can make the climate, the better off Canada will be. Just look where we all live…98 percent of us are on the border of our country, where it is warmer. It is time to face the truth - warmer is better." The change in position brought swift condemnation from environmental groups.

Enjoying a well-deserved rest in Cozumel, Mexico, a tanned Greenpolice spokeswoman Rainbow Treetower chided, "Canada will regret this decision. We are already mobilizing our workers to march on Ottawa. As soon as the St. Lawrence River is ice free later this summer, we will be sailing to Ottawa to organize widespread demonstrations."

In a curious twist, the recently cancelled "One Tonne Challenge" program, which encouraged Canadians to reduce their carbon emissions by one tonne, is being reinstated with a goal of increasing emissions by one tonne instead. "We are encouraging Canadians to do their part to improve Canada's frigid climate by increasing their energy use as much as possible. As the interior of our country thaws out, we expect a gradual spreading of people and commerce inland. We will be able to safely inhabit places where only the bravest of us have been willing to venture to up until now."

There are still some Canadians that are skeptical of the new plan, however. An employee of 'Mikes Ice Diving Rentals' in Toronto expressed concern that their wetsuit rental business will be hurt if summer water temperatures were allowed to warm up too much. "It will be economic disaster for us if it ever reaches the point where people only need to put on a swimsuit to go in the water", he lamented.

The Truth About Polar Bears vs. Global Warming

An article about polar bears by a wildlife biologist. He sees no reason to panic over the effects of climate change on the polar bear population.
Peter


Last stand of our wild polar bears
Dr. Mitchell TaylorPolar Bear Biologist,Department of the Environment, Government of Nunavut , Igloolik , Nunavut , CanadaMay 1, 2006
Tim Flannery is one of Australia 's best-known scientists and authors. That doesn't mean what he says is correct or accurate. That was clearly demonstrated when he recently ventured into the subject of climate change and polar bears. Climate change is threatening to drive polar bears into extinction within 25 years, according to Flannery. That is a startling conclusion and certainly is a surprising revelation to the polar bear researchers who work here and to the people who live here. We really had no idea.

The evidence for climate change effects on polar bears described by Flannery is incorrect. He says polar bears typically gave birth to triplets, but now they usually have just one cub. That is wrong. All research and traditional knowledge shows that triplets, though they do occur, are very infrequent and are by no means typical. Polar bears generally have two cubs — sometimes three and sometimes one. He says the bears' weaning time has risen to 18 months from 12. That is wrong. The weaning period has not changed. Polar bears worldwide have a three-year reproduction cycle, except for one part of Hudson Bay for a period in the mid-1980s when the cycle was shorter.

One polar bear population (western Hudson Bay ) has declined since the 1980s and the reproductive success of females in that area seems to have decreased. We are not certain why, but it appears that ecological conditions in the mid-1980s were exceptionally good. Climate change is having an effect on the west Hudson population of polar bears, but really, there is no need to panic.

Of the 13 populations of polar bears in Canada , 11 are stable or increasing in number. They are not going extinct, or even appear to be affected at present. It is noteworthy that the neighbouring population of southern Hudson Bay does not appear to have declined, and another southern population ( Davis Strait ) may actually be over-abundant. I understand that people who do not live in the north generally have difficulty grasping the concept of too many polar bears in an area. People who live here have a pretty good grasp of what that is like to have too many polar bears around. This complexity is why so many people find the truth less entertaining than a good story. It is entirely appropriate to be concerned about climate change, but it is just silly to predict the demise of polar bears in 25 years based on media-assisted hysteria.
