Mining Environmental, Water Shortage and Land Reclamation/Revegetation Issues

Gold miner opts for desalination to water planned Mexican mine (International Desalination & Water Reuse Quarterly – June 29, 2015)

http://www.desalination.biz/index.asp?channel=0

The gold mining arm of energy firm, Chesapeake, has opted to use desalinated seawater to supply water for its proposed Metates gold and silver mining project, in Durango state, Mexico. It has tendered for proposals to build and operate a 55Ml/d desalination facility to supply the mine with fresh water.

Chesaspeake Gold concluded that seawater desalination was the best source of water for the 30-year lifespan of the mine. This decision followed its review of a 2013 prefeasibilty study after Mexico’s water agency, Conagua, doubled the price of water this year. “Seawater reverse osmosis (SWRO) water is projected to have lower overall capital and operating costs compared with conventionally sourced surface water.” the company said in a statement.

Chesaspeake Gold found that desalination of water from the Pacific offered a cost effective, reliable and sustainable water supply compared to taking water from Conagua. “Besides the economic benefits, desalination decouples the water supply and demand for Metates,” said Chesapeake president Randy Reifel in a release.

The proposed SWRO plant would be located within the same hydrologic basin and irrigation district as current users of surface water. Chesapeake said this would simplify water transfer and trade.

AUDIO: Mining exploration causing permanent damage in Ring of Fire, Wildlands League says – by Jody Porter (CBC News Thunder Bay – June 29, 2015)

http://www.cbc.ca/news/canada/thunder-bay

Environmental group takes photos to show landscape is ‘disturbed and disrupted’

Photos released Monday by the Wildlands League are proof that mining activity is causing permanent damage in a fragile ecosystem in northern Ontario, according to the environmental group.

The pictures of a snowy boreal forest patterned with grid lines and pockmarked by drill rig indentations were taken during a March flight across the mineral-rich area, known as the Ring of Fire, in the James Bay lowlands.

The images challenge the idea that early mining exploration is benign, said Wildlands League director of conservation planning, Anna Baggio.

“I don’t think people fully grasp how much activity has happened just at the exploration stage and what is being done to the land here,” Baggio said. “If all the claims were to be developed at a similar level of intensity, it would modify the entire landscape.”

Nearly two dozen companies hold claims, spending more than $278 million on exploration in an area that has yielded “significant discoveries” of chromite, nickel and copper-zinc, according to the province’s Ministry of Northern Development and Mines.

Gold Versus Water In The Western Drought [Nevada] – by Chris Sieroty (Nevada Public Radio – June 23, 2015)

https://knpr.org/

With Nevada going through a prolonged drought, water use is a hot topic in urban areas.

The issue of drought is also being heavily debated in rural parts of Nevada because of the impact of current and future pit lakes left by mining operations.

The Progressive Leadership Alliance of Nevada recently released a hydrology study of the impacts of mining on the Humboldt River.

The study finds the largest gold mining companies use an enormous amount of water and are pumping record amounts. Will Nevada soon have to decide if water is more precious than gold?

Nevada Mining Association president Dana Bennett, Ph.D., had the following to say in response to an interview request from KNPR’s State of Nevada:

“Nevada’s mining industry has been sensitive to Nevada’s limited water resources since long before this drought began. Water is a precious resource and the drought is something all Nevada industries should take seriously.

Sudbury world-renowned for its remediation program

Researchers from as far away as Russia and Norway will gather in Sudbury for the sixth Mining and Environment International Conference at Laurentian University June 20-25.

“The goal this year is to really celebrate the successes of the Sudbury regreening program,” said Graeme Spiers, an associate professor with Laurentian’s faculty of the environment, and one of the conference organizers. “Sudbury is recognized globally for this. The citizens of Sudbury should be really proud of what the city has done.”

The “Sudbury Method,” as some have termed the city’s regreening effort, which began in 1978, has served as a model for jurisdictions around the world to remediate environments damaged by mining, smelting and other industrial activities.

Strip-mining the Ocean Floor: What Could Possibly Go Wrong? – by Miyoko Sakashita (Huffington Post – May 14, 2015)

http://www.huffingtonpost.com/green/

Miyoko Sakashita is the Oceans Director, Center for Biological Diversity.

Have you heard about the disastrous gold rush brewing in our oceans? Not content with getting minerals from dry land, companies are now aiming to strip mine our ocean floors in search of nickel, copper, cobalt, gold and other valuable metals and minerals. Many of them would end up in our electronics.

But there’s a heavy price to be paid: Like mountain-top removal mining, deep-sea mining involves massive cutting machines that will leave behind barren, underwater landscapes — some of the richest and most pristine ecosystems left on the planet.

This week, the Center for Biological Diversity (where I work) took the first steps in slowing down this deep sea gold rush by filing a lawsuit challenging the permits that the U.S. National Oceanic and Atmospheric Administration issued to a Lockheed Martin subsidiary to mine the mineral-rich Clarion-Clipperton Zone in the Pacific Ocean, about halfway between Hawaii and Mexico.

While there’s much that we still don’t understand about life on the deep sea floor, we do know that the Clarion-Clipperton Zone is teeming with wildlife, including sperm whales, spinner dolphins, loggerhead sea turtles, great hammerhead sharks and a vast array of fish, corals, snails and sponges.

REFILE-As rivers dry up, Chile copper mines turn to the Pacific for water – by Anthony Esposito and Fabian Cambero (Reuters U.S. – April 12, 2015)

http://www.reuters.com/

(Reuters) – Alvaro Badillo remembers a time when his dad would take him fishing in the stream just a stone’s throw away from the dusty streets of their small hometown of Caimanes in central Chile.

Now, like countless communities that dot the arid valleys north of the capital, Santiago, Caimanes is left with a dry riverbed. The culprit? That depends on who you ask.

For many in the town of 1,200 people, the answer lies just a few miles upstream: a 470 foot tall wall that stretches nearly a half-mile straight across the valley. It is the tailings dam for Los Pelambres, Chilean miner Antofagasta Plc’s flagship copper mine, which holds enough leftover processed rock to fill some 140,000 Olympic swimming pools.

For its part, Antofagasta blames an eight-year drought in Chile for the evaporation of already slim water resources, and says the canals it built to redirect rain water have minimized the impact on the stream.

Both sides have findings that support their arguments and are thrashing them out in a court battle that could stop work at one of the world’s biggest copper mines.

[Barrick Gold] Unprecedented sage grouse protection deal signed in Nevada – by Scott Sonner (Washington Times – March 26, 2015)

http://www.washingtontimes.com/

Associated Press – RENO, Nev. – An unprecedented attempt to protect sage grouse habitat across parts of more than 900 square miles of privately owned land in Nevada will begin under a deal Thursday involving the federal government, an environmental group and the world’s largest gold mining company.

The agreement comes as the U.S. Fish and Wildlife Service approaches a fall deadline for a decision on whether to protect the greater sage grouse, a bird roughly the size of a chicken that ranges across the West, under the Endangered Species Act.

Commercial operations, including mining companies and oil and gas producers, are entering into such deals in an effort to keep the bird off the threatened or endangered list because the classification would place new restrictions on their work.

The deal involves Barrick Gold Corp., The Nature Conservancy and the U.S. Interior Department’s Bureau of Land Management and Fish and Wildlife Service. It establishes a “conservation bank,” providing the mining firm credit for enhancing critical habitat, in exchange for flexibility in future operations. It aims to preserve and restore more habitat than is lost through development while at the same time providing Barrick with more certainty as it maps out new mining plans.

“This is the kind of creative, voluntary partnership that we need to help conserve the greater sage grouse, while sustaining important economic activities on western rangelands,” Interior Secretary Sally Jewell said.

Sudbury Accent: The prodigal ling returns to Ramsey – by Bruce Heidman (Sudbury Star – March 21, 2015)

The Sudbury Star is the City of Greater Sudbury’s daily newspaper.

They aren’t even close to pretty and their song is not nearly as sweet, but the return of ling to Sudbury’s Ramsey Lake after a 100-year absence is serving as a veritable canary in a coal mine.

Local fish biologists were stunned when it came to their attention that ling, an environmentally sensitive cold-water fish also commonly known as burbot, have returned to Ramsey, where the last recorded catch came in 1912. The discovery is significant because it shows the lake has bounced back even better than scientists thought from decades of environmental degradation, mostly due to sewage, mining and acid rain.

Local biologist John Gunn, one of a handful of scientists who have done extensive research on Ramsey Lake, Sudbury’s crown jewel, for the better part of 30 years, didn’t believe the news when he first heard it.

“We were shocked,” he said. “We didn’t think for all the work and time we have spent around that lake that something like that would slip by us. They are not a species people move around and they are a very clean water fish that has been lost in Killarney and Temagami, and the ling disappeared before the lake trout, so when we saw a pollution-sensitive species disappear and then start swimming around in front of the (Living With Lakes Centre) building, we were surprised.

Here’s What Coal Mining Is Doing to Communities in the Navajo Nation – by Laura Dattaro (Vice News – March 18, 2015)

 

https://news.vice.com/

For sixty years, the billions of tons of coal found beneath Arizona’s Black Mesa have powered the cities of the Southwest. But getting at all that coal has meant the displacement of more than 12,000 people of the Navajo Nation, one of the largest removals of Native Americans since the 19th century. For those that have remained, the mining process has compromised their health and their environment.

The mesa rises up from the dry Arizona landscape a few miles south of Kayenta Township, where Peabody Energy operates a mine that in 2013 produced nearly eight million tons of coal. The company proposed in May 2012 to expand its excavation, a plan that needs approval from the Interior Department’s Office of Surface Mining, Reclamation, and Enforcement (OSMRE). Locals are concerned because that would add 841 acres of land to the Kayenta Mine complex — which would displace even more Navajo and ensure continued air and water contamination for decades to come.

A VICE News crew traveled to the Black Mesa area to document the effects of coal mining on their health, the environment, and the local economy.

Sudbury’s Environmental Revival – by Boghos Ghougassian (Arab Forum for Environment & Development – December 1, 2012)

http://www.afedonline.org/en/

The Greater Sudbury area in Ontario Province, Canada, 400 km north of Toronto city, was one of the earliest regions of the world to feel the harmful impact of unsustainable industrial development. It was also one of the first to recognize the mistakes and determined to correct them.

For nearly a century, mining and logging activities had converted the Greater Sudbury area into an inhospitable land. It had been dubbed as moonscape, its blackened scar visible from outer space. Even the Apollo 16 astronauts have done their exercises in here in 1971, before landing on the moon surface.
Greater Sudbury encompasses one of the largest known nickel ore bodies on Earth, with an area of more than 60 km2. This has earned Sudbury international recognition as “the Nickel Capital of the World”.

Sudbury was found in 1883 as a railway station town. So dominant were the trees, the Jesuits called their parish “Ste. Anne of the pines”. The trees also caught the attention of wood logging companies who clear cut the area leading to loss of biologic diversity, erosion of soils and other environmental impacts. Records indicate that Sudbury’s forests have been swarmed with some 11,000 loggers during the late 1880s.

With the discovery of nickel, early mining and smelting processes in 1886 to 1929 delivered another devastating blow to the environment. The metal rich rock was ignited in open “roast beds” cloaking the area in dense clouds of sulfur dioxide’s acidic smoke, which devastated the remaining green vegetation and acidified the freshwater of many lakes of the region, killing fishes and many other aquatic species.

Future Fumes?: Will Sudbury super stack be needed by Vale after retrofit project? (Canadian Mining Journal – February/March 2015)

http://www.canadianminingjournal.com/

At more than 388m high and just over 36m wide at base, Vale’s “Super Stack” in Sudbury is unquestionably the city’s most outstanding feature.

In fact, it’s also one of Northern Ontario’s more outstanding features because it’s literally the tallest structure in the north and can be seen for miles from every direction as it towers over the city.

Even Sudbury’s world-renown “Big Nickel” pales by comparison when it comes to size and impressive landmarks. Built from almost 16,500m3 of concrete and strengthened with nearly 956 tonnes of 38mm and 13mm re-bar, the stack is a solid monument that has withstood the harshest of conditions that Mother Nature could throw at it.

Extreme cold and blowing snow, fierce winds and driving rain, heat and lightning, and even ground-shaking tremours, have barely made a mark on the stack. And, the fact that it’s also lined from top to bottom with 6.4mm nickel stainless steel and that its walls are 1.1m thick at the base and 267mm at the top, have all added to make the stack almost indestructible.

It was clearly built to last and since it started rising on the horizon in 1970, and subsequently going into service on August 21, 1972, the stack has performed as planned by safely carrying sulphur dioxide from INCO’s (now Vale’s) Copper Cliff smelter high into the atmosphere and away from the city.

Drought in Chile curbs copper production, to trim global surplus – by Eric Onstad and Rosalba O’Brien (Reuters Africa – February 25, 2015)

http://af.reuters.com/

LONDON/SANTIAGO, Feb 25 (Reuters) – A drought in Chile is hampering copper production, a water-intensive business, in the world’s biggest producer of the metal, one more factor that could trim an expected surplus this year.

Both Anglo American and BHP Billiton have said the extremely dry conditions have hit production due to restrictions on water, used for everything from toilets for workers to separating the metals in the ore body from waste rock and tamping down dust that heavy trucks kick up.

“The one caveat or the risk I think that we need to flag… is Chile is still in drought,” Anglo Chief Executive Mark Cutifani told a results presentation last week. “It remains a risk, and in fact it was impacting our operating performance in November and December.”

In some parts of Chile, January was one of the driest since records began, exacerbating a drought that began in 2007, said Chilean meteorologist Claudia Villarroel. Winters in central Chile are becoming drier because of climate change, she added.

Indeed, Anglo’s Los Bronces mine in central Chile has been the worst affected of the company’s mines. It warned that water scarcity at the mine, the world’s sixth-largest copper producer, could cut as much 30,000 tonnes or 4 percent off Anglo’s overall copper output this year.

Leaders hope to inspire new [economic] visions for Sudbury – by Jim Moodie (Sudbury Star – January 28, 2015)

The Sudbury Star is the City of Greater Sudbury’s daily newspaper.

Four community leaders came together Tuesday at a chamber of commerce event to share their thoughts on what makes Sudbury an attractive place to live and what will enhance its culture and economy going forward.

Sean Murray, head of pediatrics at Health Sciences North, said his dream is to create a freestanding medical facility for children in Sudbury.

“I really want to inspire the City of Greater Sudbury, and our rural communities as well, to try to improve health care for children, who unfortunately often get left in the mix of everything else that goes on,” he said.

Murray said he had performed a procedure earlier in the day on a boy who has chronic medical issues, including autism spectrum disorder, and was suffering from headaches. “I had to stick a needle into his back to take spinal fluid out and measure how much pressure was in his brain,” he said.

But since the boy has particular sensitivities to needles and crowds of people, the procedure had to be done in OR. “It really highlighted for me the importance of having something that is child-friendly,” he said. “We need to minimize those types of traumas that kids go through.”
