Miners injured when gold mine

Sunday, January 8th, 2012

Three men injured while working at an underground gold mine site in the state’s Goldfields have been taken to Royal Perth Hospital for further treatment.

The men were flown to Perth by Royal Flying Doctor Service and then taken by St John Ambulance to hospital as trauma patients suffering from chest injuries, bone fractures and a suspected spinal injury.

The two miners and a contractor were injured when a sheet of construction material fell on them at the Agnew gold mine, located about 23 kilometres west of the Leinster townsite.

Two RFDS planes were sent, one from Kalgoorlie and one from Perth, to bring the men to Perth for further X-rays and treatment.

The men, aged in their late 20s and 30s, were assessed by an RFDS doctor and found to be in a serious but stable condition, with non-life threatening injuries, according to RFDS spokeswoman Joanne Hill.

One of the men has possible spinal injuries as well as broken limbs, she said.

The 31-year-old man suffering chest injuries was the first to land at Jandakot, followed shortly by a 26-year-old man with the possible spinal injury and a fractured arm, Channel Ten reported.

A 38-year-old man suffering from a fractured leg accompanied the 26-year-old man and all three men were conscious throughout the flight, according to RFDS doctor Sally Edwards.

It is understood the men were constructing an explosive storage area when a piece of concrete reinforcing mesh fell on them. The mesh was not part of the underground mine, which is owned by South African gold producer Gold Fields.

Gold Fields said it alerted authorities to the incident this morning.

The Department of Mines and Petroleum has confirmed it is investigating the incident.

“Mine safety inspectors from the department are now making inquiries into the incident, which will be subject to a formal and thorough investigation,” a spokeswoman said.

“The department will take any necessary appropriate action upon collection of all evidence.”

Duran expands molybdenum mineralization areas

Thursday, November 17th, 2011

Canadian-based Duran Ventures has expanded the areas of known copper and molybdenum mineralization of its Aguila project located in the department of Ancash in north-central Peru, after finishing the final eleven drill holes of the 2011 drill program, the company reported.


Drilling has intersected mineralization over 800 metres in an approximately east-west direction, 400 metres in a north-south direction, and over 1000 metres vertically.

Limits on the size of the mineralized system have not been fully established, with numerous geological, geochemical, infill, and geophysical targets remaining to be drill tested at this large property, added the company.

Further drilling is required to define the ultimate shape, size and orientation of the Aguila Copper-Molybdenum Porphyry system.

According to Duran Ventures, a total of 15,175 metres were drilled in 27 diamond drill holes from April 18th to October 19th, 2011. Meanwhile, a cumulative total of 23,929 metres of core have been drilled by the company at the Aguila project from 2007 to 2011.

Data from all the holes will be included in the preliminary NI 43-101 compliant resource estimate now being prepared by SRK Consulting. The company expects to receive the SRK report in the first quarter of 2012.

The preliminary metallurgical test work currently being carried out by G & T Metallurgical Services Limited of Kamloops, British Columbia, Canada is expected to be available at the same time.

The 119.5 metre interval from 161.5 to 281.0 metres depth returned 0.32% Cu and 0.008% Mo (0.38% Cu equivalent).

At the same time, Compañia Minera Milpo S.A.A. is advancing development work at the Magistral copper – molybdenum porphyry and skarn deposit, located some 40 kilometres to the north of Aguila.

Molybdenum Long, strong intersections at former Kitsault mine

Tuesday, November 15th, 2011

Avanti Mining of Vancouver is hitting long and strong intersections at the former Kitsault molybdenum mine north of Prince Rupert.


The best hole returned 0.378% Molybdenum over 85.4 metres. The company is drilling south of Patsy Creek near the mine and at Roundy Creek 4 km to the west.

At Roundy Creek, the strongest mineralization is in ‘unidirectional solidification texture quartz’ layers containing molybdenite.

Avanti says it has encountered mineralisation in this type of formation that is tens of metres thick with grades of more than 1% Mo.

A 2010 feasibility study for Kitsault proposed an open pit mine and 40,000-t/d conventional flotation mill with SAG-ball mill-pebble crusher circuit. Concentrate would be shipped to a third-party processor.

Thompson Creek looking for more funding

Thursday, November 3rd, 2011

The company showed on Tuesday that it sees a potential funding shortfall of US $100-million to US $300-million over the next two years, according to RBC Capital Markets analyst Fraser Phillips.

The exact size of the shortfall depends on molybdenum prices.

“A gold related financing at the upper end of the US $100-million to US $300-million range could significantly reduce the financing risk and relieve some of the downward pressure on the share price,” Mr. Phillips wrote in a note.

Despite the low share price and the struggling molybdenum market, Mr. Phillips sees good things ahead for Thompson Creek and has an outperform rating on the shares.

“We continue to believe that molybdenum prices could strengthen significantly over the next two years because of the cancellation or delay of a number of new projects that will be required to meet future demand. [Thompson Creek] is well positioned to take advantage of any increase in price,” he wrote.

Gold mine approved

Sunday, October 23rd, 2011

National Park convener Linda McKay said: “Without question, this has been the largest and most complicated planning application we have ever had to consider.

“As guardians of some of the most stunning scenery in Scotland, it would have been easy to refuse the second application if we were considering the short-term impact on the landscape, but this National Park plans for long-term conservation management, and that includes having the vision to see beyond the temporary life of the gold mine.”

Scotgold Resources originally applied for planning permission to explore the mine last year but it was rejected due to concerns over the size and shape of the tailings management facility (TMF) and poor restoration proposals for the long-term future on Glen Cononish.

Scotgold and the National Park Authority worked together to find solutions to the objections.

Ms McKay said: “We also have a 30-year commitment to improve the wider Glen Cononish. The Greater Cononish Glen Management Plan will include extending existing native Caledonian pine forest and improving habitats and access tracks.

“This legally-binding agreement means the glen will regain its quiet, remote character following closure of the mine and the landscape will be improved from its current state.”

Climax molybdenum mine in 2012

Thursday, August 4th, 2011

“Freeport will restart its Climax molybdenum mine in 2012 and ramp up production rates at some North and South American copper mines in an effort to add to its expansive resource base” its chief executive said.

“The molybdenum markets we believe look good. We have made the decision now to restart Climax,” CEO Richard Adkerson said Thursday during a second-quarter earning conference call with Wall Street analysts.

 

“As we stand right now, engineering is complete, construction is 75 percent complete with the summer season. We’re actually mining now and we’re going to go forward, complete this construction early in 2012 and start our ramp-up at that time.”

By 2013, production was estimated to ramp up to £20 million a year.

Silver reveals significant increase San Jose resources

Sunday, July 31st, 2011

Arian Silver Corporation has told of a specific increase in mineral resources at its 100%-owned San Jose property, in Zacatecas State, Mexico.

CEO Jim Williams said: “Today’s updated mineral resource confirms the potential for large scale silver mining at San Jose.

“Overall contained silver has increased by over 100% from the company’s resource estimates from August 2008, and with some 34% of the resource now in the indicated category.

“As previously announced there are several wide intercepts of high grade silver and base metal mineralisation within the existing SJV resource envelope, which remain to be fully quantified.”

African gold miners strike

Monday, July 25th, 2011

Its said that the action, which was scheduled to begin with the night shift and could involve tens of thousands of workers, will affect 3 main mines other smaller miners operating in the world’s fifth-largest producer of gold.

Basically ‘the strike was called when wage talks broke down after the National Union of Mineworkers, which has been demanding 14 per cent pay rises, rejected the companies’ offers of between 7 per cent and 9 per cent increases. The industrial action comes at a time when gold prices have soared to record highs of more than $1,600 per ounce’.

AngloGold Ashanti, South Africa’s biggest gold producer, said “it would be forced to cease mining operations because of the industrial action, with only essential services continuing”.
“We are trying to resolve it as quickly as possible,” the company said. “The economic damage will depend on how long it goes on.”

Molybdenum is important

Wednesday, July 13th, 2011

Molybdenum is an indispensable ingredient in the steels used in mining equipment. It adds strength and wear resistance to the machines used to dig and process ore. It brings corrosion resistance to the chemical processes used in many mining operations. It even finds its way into the lubricants that keep the machines from breaking down. Here we focus on molybdenum in the machinery that digs, shovels, hauls, crushes, grinds and mills the rock to extract valuable raw materials.

Nearly everything we use in our daily lives was once a resource in the ground, often present in miniscule percentages. However, Mother Earth does not give up her treasures easily! Someone has to find that resource, extract it from its home in the earth and enrich it in order to create a useful raw material for material suppliers. To do this, miners dig, crush, grind and mill enormous quantities of rock, stones and dirt and transport them from place to place in the process. The quantities of material and its hardness place great stresses on the equipment used. All along the chain of converting dirt to useful raw materials,

Moly plays an important role. It adds service life to the equipment used throughout the mine and plant, lowering the cost of production and bringing into everyday reach materials and products that we consider indispensable.

Indonesia offers part of Newmont mine

Sunday, June 19th, 2011

Indonesia’s central government is offering a quarter of its 7 percent stake in the local unit of Newmont Mining Corp to the regional government where the company’s copper and gold mine is located, the finance minister said on Tuesday.

“The reason is for the national interest. And we believe this is a step further to build the nation,” said Martowardojo, without giving further details on why he is making the offer.

“This is a smart way from Agus Martowardojo to shame Bakrie because Golkar will now be forced to accept the scheme,” said political analyst Burhanuddin Muhtadi from the polling agency Indonesian Survey Institute.

“With this gesture, Martowardojo is accommodating the local government’s wish as well as Bakrie’s.”
