Mining report: Limestone is a lifeblood on Texada Island


As the proposed transfer point for thermal coal shipped from an expanded Fraser Surrey Docks destined for Asia, Lafarge’s (Euronext:LG) Texada Quarrying Ltd. has been wrapped up in a heated jobs- versus-environment battle for much of the past year.
But beyond the contentious coal debate, Texada Quarrying, a large-scale limestone quarry located on Texada Island, has another story to tell. At 61 years old, it’s the oldest mine in British Columbia. And it isn’t slowing down any time soon.
“Texada Quarrying is a very, very sustainable operation for us. We believe it’s a 200-plus year deposit,” said Jonathan Moser, director of environment and public affairs at Lafarge.
“We see it as a resource that will serve our business for a long time.”
On average, Texada Quarrying produces about four million tonnes of limestone per year. Its record year was in 2008, when 8,000,000 tonnes of limestone was produced. The quarry currently employs 90 people.
All of the limestone mined at Texada is barged – the quarry has a port facility, one of the reasons it is being considered as a transfer facility for the coal from the Fraser Surrey Docks expansion – to a cement plant in Richmond, also owned by Lafarge. Limestone is the main ingredient used to make cement.
That industrial use, said Moser, is a source of pride for Lafarge. Because cement is routinely used in sidewalks, curbs and bridges, to name but three examples, a constant supply of it is critical.
“This is a commodity that goes into many facets of people’s everyday lives,” said Moser.
“It is central to our infrastructure needs. It all begins with the mining of limestone.”
Texada Island has a rich history mining limestone. Prospectors first started mining limestone on the island, in small operations, in 1918. In the 1930s, however, the industry starts to grow.
“Texada was very, very active in mining in those days,” said Heather Harbord, a Powell River-based writer who wrote a book on the history of the island.
“It was just going gangbusters.”
The most influential player in Texada’s limestone history was businessman Fred Beale. In the early 1930s, Beale bought his first limestone quarry on Texada, on the east side of the island, from the Powell River Company. He ran the quarry for years before eventually passing it on to his son, Stan, to manage.
In 1952, Beale started Texada Quarrying. In 1956, Beale sold the quarry to a company called Ideal Cement. Ideal sold to Holderbank North America, a Swiss company now known as Holcim Group (LSE:HOLN), in 1989. Finally, the quarry was sold to Lafarge in 1998.
Pete Styles, a longtime resident of Texada Island, was hired by Stan Beale in 1966 to develop limestone projects on the west side of the island.
In his more than 30-year- career, the now 84-year-old Styles worked on numerous limestone jobs, managing everything from simple rock-crushing sites to helping build a barge-loading facility in Beale Cove named after Fred Beale.
It was good work and it paid the bills, Styles said. But it wasn’t just a gig that kept his family clothed and fed. Limestone mining has sustained the island.
“If it weren’t for limestone, Texada Island would be a retirement community,” said Styles.
“And if we were just a retirement community, there would be no school and real future. A retirement community can only last for so long.”
And like Lafarge’s predictions, Styles believes limestone mining will keep future generations at work on Texada.
After all, the world needs limestone, he said.
“I’m not surprised it’s the oldest operation in the province. People use limestone all over the place,” said Styles.
“We’re going to keep using it. As long as we’re building bridges, we’ll keep mining limestone. It’s small price to pay for the benefit of everybody.”

Rupee depreciation

ndian rupee is one of the worst performance currencies of the world in these days. Mukesh Ambani, the richestman in India, has lost $6 billion as rupee dives. The chairman of Reliance Industries, operator of the world’s biggest oil refinery complex, has lost $US5.6 billion ($6.2 billion) of his wealth since May 1, as the rupee’s plunge accelerated. It is said that India government is planning to lease out 200 tonnes of gold in international market to increase rupee value. However, the plummeting rupee can’t stop Indiansfrom buying the gold. The gold price inside India has hit a nine-month record high in India’s domestic market over the weekend. With the ratio of rupee todollar is 65 to 1, the gold price in the Indian market is the same as it was when gold was $1800 per ounce. Based on the latest trade figures in July thecountry bought $2.9 billion worth of gold.

  Read more:Imported Iron Ore Dilemma in China In recent years, it’s becoming increasingly a tough issue to import iron ores. Chinese steel mills and traders are in the dilemma. The iron ores produced by the three biggest mines are of high quality, but also high in price. While iron ores produced by others are not stable in quality. According to China Entry-exit Inspection and Quarantine Bureau in Port Jingtang, there were 14 batches of iron ores imported from Mexicoand all of them are below the standard. China has been importing from various countries including Australia, Brazil, India, etc. The three biggest iron ore mines are selling at very high price relying on their monopoly position. However, someiron ore export countries is raising export tariff and their iron ores’ quality are not stable with possible problems such as high sulphur content or low irongrade. The off-grade iron ores can still be used but need extra processing. But it would increase the cost and pollute the environment. Some people propose that steel industries could solve the problem from two aspects: encourage domestic iron ore mining and enlarge overseas investment. However, it’s easier said than done.

Former Cliffs CEO named as Newmont CFO



Newmont Mining Corp., the largest U.S. gold producer, named Laurie Brlas, a former Cliffs Natural Resources Inc. executive, as its chief financial officer.
Brlas will begin at Newmont on Sept. 9, the Greenwood Village, Colorado-based company said in a statement today. She spent six years as CFO at Cliffs, the largest U.S. iron-ore miner, and was the company’s president of global operations when she departed in July.
Newmont said its interim CFO Tom Mahoney will return to his previous role as treasurer. Mahoney stepped in after former CFO Russell Ball quit in May to become executive vice president of capital management at Vancouver-based Goldcorp Inc., the world’s largest gold company by market value.
Newmont is among gold companies that have lagged behind the price of the metal over the past year as mining costs have increased. The NYSE Arca Gold BUGS index of gold producers has dropped 44 percent in the period while gold for immediate delivery has declined 17 percent.
Gold slipped into a bear market in April after rising for 12 consecutive years. Prices may average $1,297 an ounce next year, compared with $1,412 in 2012, according to the median of analysts’ estimates compiled by Bloomberg.

SINGAPORE: Gold clung to gains made in the previous session on sporadic safe-haven buying as U.S. President Barack Obama won support from key Congressmen for a limited strike against Syria.
Obama secured the backing of Republicans John Boehner and Eric Cantor in his call for limited U.S. strikes on Syria to punish President Bashar al-Assad for his suspected use of chemical weapons against civilians.
Leaders of the U.S. Senate Foreign Relations Committee said they reached an agreement on a draft authorization for the use of military force in Syria that was much narrower than the request made by Obama, paving the way for a vote by the committee on Wednesday.
Spot gold edged up 0.06 percent to $1,412.84 an ounce by 0348 GMT on Wednesday, after pushing past $1,400 in the previous session as a missile test by Israeli forces training in the Mediterranean with the U.S. Navy set nerves on edge.
"Markets are very quiet today as we are waiting for more developments in Syria," said Peter Fung, head of dealing at Hong Kong's Wing Fung Precious Metals.
"Until then we will be in a very tight trading range. It looks like prices can go either side from here but tensions in Syria situation will give some support."
Rising geopolitical tensions spur safe-haven buying in gold as investors dump riskier assets such as stocks.
Asian shares slipped on Wednesday after a four-day winning run as the likelihood for action against Syria increased.
"The potential for Mideast tensions to intensify would be bullish for bullion," HSBC analysts wrote in a note. "A key reason for gold to rally in response to Mideast tensions is the potential for oil supply disruptions that a U.S. strike or an escalation of the conflict may trigger."
Gold is seen as a hedge against oil-led inflationary pressures.
Gold prices were also supported by labour strikes that began in South Africa's gold mines, with some workers failing to go underground for the evening shift.
The stoppage was called by the National Union of Mineworkers, which represents two-thirds of the workers in South Africa's gold mines, after talks between unions and companies broke down last week.
SPDR Gold Trust, the world's largest gold-backed exchange-traded fund, saw its holdings fall 1.8 tonnes on Tuesday to 919.23 tonnes but they were still 10 tonnes above a four-year low hit in early August.

Australia’s Perilya likely to be swallowed by Chinese firm, its major shareholder


Perth-based miner Perilya (ASX:PEM), which owns the famous Broken Hill lead-zinc-silver mine that gave birth to BHP Billiton, is likely to be absorbed by Shenzhen Zhongjin Lingnan Nonfemet Co (SZLN) —its major shareholder— in a deal worth around US$180 million.
According to The Australian, the State-owned Asian firm, which is now one of China's largest zinc-lead producers after acquiring 50.1% of the Aussie company in 2009, is fine tuning details for a takeover bid.
The article quotes sources close to the companies as saying it is almost impossible that any group other than Zhongjin Lingnan bids for Perilya, not only because the Chinese group is already the Aussie miner's main stakeholder, but especially given the “traditional reluctance of Chinese companies to compete for control of the same asset.”
Perilya, which posted its half-year financial results on Friday, went into a trading halt because of a "potential control transaction.”
In October last year the Land and Environment Court found that Perilya's three mines in Broken Hill, located west of outback New South Wales, were worth $5.9 million rather than the $21 million they had been valued at by the Valuer-General.
Earlier this month, Australia’s Supreme Court ruled that both the Valuer-General and the mining company made errors in working out the value of Perilya’s mines in Broken Hill.
The company reported today a net loss before tax of A$29.2 million, down from a net profit before tax of A$8.3 million in the same period last year. Revenue from operations for the period dropped to A $139.1 million, down 14% from the $161.3 million logged in the first half of 2012.
BHP’s name stands for "Broken Hill Proprietary."

Mutiny scoping proves Rocksteady true


A scoping study into ASX-listed Mutiny Gold’s Rocksteady iron project, in Western Australia, has proved positive, prompting the company to start the permitting process.
The Rocksteady project is hosted in Mutiny’s Gullewa tenement, which also plays hosts to the flagship Deflector gold project.
MD John Greeve said on Friday that while the Deflector project was Mutiny’s key project, the company had a multi-mine strategy which encompassed additional gold and iron mines.
“Our Gullewa tenements contain vast mineral wealth including 170 km of banded iron structure. Rocksteady is the first of potentially several iron deposits which may be commercially developed,” said Greeve.
The scoping study was based on an initial Joint Ore Reserves Committee-compliant resource of 650 000 t at 54% iron, and contemplated an openpit operation with an on-site plant potentially producing four products, including lumps and fines.
Greeve noted that Mutiny, along with a number of customers, had identified a window of opportunity to bring the iron-ore potential of Gullewa to the market through the growing iron-ore infrastructure assets being developed in the region.
“The completion of this study allows us to negotiate the key offtake contracts with a sound understanding of the project dynamics,” he added.
Greeve said that fundamentals of the proposed development included an exploration target of some 4.5-million tonnes of direct shipping ore, along with an estimated equivalent quantum in upgraded ore from the lower-grade waste to be mined as part of the operation.

CHINA has cast aside its own concerns about its perceptions in Australia and re-emerged as the largest foreign acquirer of resources assets in the nation.
An analysis by The Weekend Australian found that Chinese interests bought $5.4 billion worth of Australian-owned mining and energy assets during the 2013 financial year, eclipsing Japan and Canada as the most active foreign investor in the sector.
