Falling ferro-tungsten prices in Europe could be linked to lower-quality material being sold on the continent, perhaps unknown to market participants.

Metal Bulletin’s price quotation for ferro-tungsten on an in-warehouse Rotterdam basis is nominally based on material with 75% tungsten content. However, Jane Parish, the European representative of Vietnam Youngsun Tungsten, has suggested the price may be falling because the material being sold contains high levels of impurities.

Australian tungsten producer Carbine Tungsten has entered a Memorandum of Understanding (MoU) with offtake partner Mitsubishi Corporation Unimetals (MCU) to support the development of its existing hard-rock stockpiles and historic open pit tungsten mine.

MCU, part of the Mitsubishi Group, intends to provide funding for Carbine’s hard-rock project, and to continue to participate in the offtake agreement once Carbine moves into the development phase for these assets, the company said on Monday February 25. The MoU includes potential financing and technical support for the development of the hard-rock project, and an offtake consideration for 80% of the tungsten stockpiles and 50% of the ore produced from the historic open pit tungsten mine, Carbine said. MCU has also begun its consideration to fund A$15 million ($15.5 million) of the capital requirement for Carbine’s planned development programme of the existing stockpiles, which is the company’s main focus.

Miners have pulled gold, silver, arsenic and tungsten out of the ore in southwestern Tooele County dating back to the 1860s.

Now, under a proposal pitched to the Bureau of Land Management, the Clifton-Gold Hill Mining District may become home to the area's first large mining operation to tap gold and silver deposits.

Seattle-based Desert Hawk Corp., wants to set up camp in the west desert and process a million tons of ore a year for two years. The entire life of the mining operation would be for six years, with another three years to reclaim the land.

Desert Hawk President Rick Havenstrite said about $12 million has been spent so far to get the project rolling, including money sunk into documentation for regulators that there won't be a problem with acid mine drainage, which is acidic water laden with iron, sulfate and other metals.

"Our system doesn't have sulfate in it — that's the beautiful thing," he said.

What's been dubbed the Kiewit Mine Project has gone through an environmental analysis by the Bureau of Land Management because part of it is on federal lands east of Iabapah and west of the salt flats. The public has a chance to weigh in on the proposal through March 14 and a similar public review of a state mining permit has already been completed.

Jim Springer, spokesman with the state Division of Oil, Gas and Mining, said no negative comments were received on the project, which involves exploratory drilling, blasting, an open-pit mine and a process to extract the gold and silver using cyanide.

While the division is a long way off in the permitting arena, the project's proposed use of what's called "cyanide heap leach pads," would be the state's only active mining operation using this extraction method.

Using cyanide

Cyanide is highly toxic and state mining regulators say the word itself alarms people. They say if it is handled properly it is safe in these types of applications.

The compound has been used in gold mining since the 1880s and continues to be used in more than 90 percent of the world's gold production today. In neighboring Nevada, there are about 30 mines that use the cyanide process to separate gold and silver from ore.

"Even though this may be slightly new to Utah, the regulatory environment is well known," Havenstrite said, adding that it is a fairly simple process.

Basically, the mounds of rock are piled on a lined pad that receive a cyanide solution through a drip application, he said.

"We mine it, crush it and sprinkle it on," he said. "Cyanide bonds to the gold and silver and carries it out. They are all in liquid form."

In its analysis of the project, the BLM notes that the cyanide would be trucked to the site from Nevada from a company with employees certified in safety procedures for handling the compound.

China has approved funding to develop core technologies for nuclear-powered ships. Professionals speculated that Beijing is planning to build nuclear-powered aircraft carrier.

Reported by China Daily reported, China Shipbuilding Industry Corp. said that one of its research institutions has received State approval and funding to formally begin research on core technologies and safety for nuclear-powered ships.

A senior researcher at the People's Liberation Army's Academy of Military Science told the Daily that Nuclear-powered ships can travel farther and are more reliable compared with used conventional propulsion. Factors make the ships a wise choice for polar expeditionary missions.

Reported many military followers link the announcement to widespread speculation that China may develop its own nuclear-powered aircraft carriers.  
China launched its first conventional aircraft carrier last year which is still undergoing trials.

Profesional said that China already has the technology and industrial capability to develop and build a nuclear-powered aircraft carrier.  

The only operating aircraft carrier outside the US is France's Charles de Gaulle, also the first French nuclear-powered surface vessel.

As we have known, thanks to tungsten’s particular properties, tungsten products are widely used in aerospace and aviation, especially under harsh environments.

Montreal-based explorer Colt Resources(GTP-V) tumbled to a new 52-week low after announcing it received two experimental mining licenses allowing it to advance its tungsten and gold exploration projects in Portugal, likely not the reaction the company was anticipating. The stock dropped nearly 16% to close Feb. 20 at a year low of 32.5¢. The next day it shares rebounded, gaining 17% to end at 38¢.    

Government officials granted the junior a 45-sq.-km experimental mining licence or EML for its Tabuaço tungsten project located some 300 km north-northeast from the country’s capital Lisbon and 100 km east-southeast of Porto.

The advanced-stage tungsten project sits near the city of Vila Real in Colt’s 100%-owned 218-sq.-km Armamar-Meda exploration concession, which partially surrounds its Penedono and Moimenta-Almendra concessions.

The EML covers the Tabuaço skarn-type tungsten deposits, including the Sao Pedro Aguias (SPA) and Aveleira tungsten resource areas, exploration targets on the SPA-Aveleira Gap, the Quinta-Tavora zone, and the East bank of the Tavora River.

The licence came after Colt spent nearly six years exploring the property, after staking it directly from the Portuguese government in December 2007.

Since then the junior — with big ambitions of bringing the country’s next gold and tungsten mines on stream in the next two to three years — carried out extensive outcrop sampling work followed by a diamond drilling program. To date, it has punched more than 100 holes or 11,400 metres at Tabuaço to help delineate a NI 43-101 mineral resource.  

The most recent estimate, published last October, show the SPA and Aveleira deposits host 1.49 million tonnes grading 0.55% tungsten trioxide (WO₃) in indicated, with another 1.23 million tonnes of 0.59%  WO₃  in inferred, using a 0.3% cutoff grade.  

While the Montreal-based entity aims to keep exploring the tungsten property, its experimental mining program will focus on the SPA deposit, where it will excavate an access adit and a vertical shaft to test the proposed mining method, evaluate the rock mechanical conditions, and recover a bulk sample to complete pilot ore concentration work.

Earlier this year, Colt provided a small representative sample of drill core to a Chinese metallurgical services provider to test recoveries. It reported flotation followed by acid leaching returned overall tungsten recoveries of 87%, as well as a final concentrate grading around 70% WO₃ from an ore sample containing 0.64% WO_3.

“These final metallurgical test results further demonstrate the potential to develop a successful tungsten mining operation at Tabuaço,” Nikolas Perrault, the company’s CEO, stated in a Jan. 30 release.

Colt intends to wrap up a preliminary economic assessment on the project by July, Perrault said, adding it is actively pursuing a joint-venture partner for Tabuaço so it could concentrate on its gold projects.

At the beginning of this century, when Inner Mongolia North Heavy Industries Group seeked a strategic value of technology from abroad, encountered many setbacks; however, though that company was suffering a setback but then braved. Many decades, North Heavy Industries Group adheres to innovation; constantly breaks the foreign technology blockade, finally to fill a blank in the field of high-end equipment manufacturing in China.

Commodity natural resources company Premier African Minerals yesterday said a recent exploration update from its flagship RHA tungsten project, in Zimbabwe, indicated the potential for development of a low-capital and low-operating-cost mine in the near term.

A five-hole diamond drilling programme undertaken on site confirmed significant tungsten oxide values.

“This update has revealed significant tungsten mineralisation in the form of very coarse wolframite crystals hosted by quartz veins identified from drillhole intersections and highlights the exceptional prospectivity of our RHA tungsten project,” Premier chief executive officer George Roach said in a statement.

Drilling had also potentially uncovered three previously unknown, well-mineralised quartz veins in the existing lode system. Further low-cost surface trenching and sampling would be undertaken in the first quarter of the year to confirm the surface location and extent of the hanging wall lodes, with a South African Mineral Codes-compliant resource on target for completion within the first half of the year.

“In tandem with this, we are also completing a conceptual mine study, which will determine the most beneficial and cost-effective method of exploiting the known extent of the RHA deposit,” Roach added.

Premier African Minerals, the London AIM market listed natural resources company has revealed the discovery of two “well mineralised” veins that could see the company expand into Zimbabwe through the opening of a low-cost tungsten producing mine.

The company is expecting to venture into tungsten mining in the Kamativi tin belt in Zimbabwe, saying it will commence operations “in the near term”. Zimbabwe is considered a lucrative destination for mining investors despite concerns around the country’s empowerment policy, which compels foreign firms to cede 51 percent shareholding to black groups.

“This update has revealed significant tungsten mineralisation in the form of very coarse wolframite crystals hosted by quartz veins identified from drill hole intersections, and highlights the exceptional prospectivity of our RHA tungsten project,” said George Roach, the company’s chief executive officer.

He said Premier African Minerals was planning to carry out further surface trenching and said sampling was scheduled to be undertaken before the end of March. This would be undertaken to ascertain and confirm the mineral surface location and establish other details.

“It is now our intention to conduct low-cost surface trenching and sampling to confirm the extent of these newly identified quartz veins and define a maiden SAMREC compliant resource in H1 2013.

“In tandem with this, we are also completing a conceptual mine study, which will determine the most beneficial and cost-effective method of exploiting the known extent of the RHA deposit,” he added.

The company has previously said it had struck an agreement in Mali that would see it retain exposure to its properties in the West African country as well as the highly prospective Danakil property, in Ethiopia, through its shareholding in EPC.

Under this arrangement, Premier African Minerals will be able to avoid significant exploration costs in ascertaining and quantifying the significance of the projects.

“On a wider level, we continue to implement our business strategy of building shareholder value through strategic, cost-effective acquisitions and joint-venture partnerships, while advancing our multi-commodity portfolio that already consists of preproduction assets and early-stage exploration projects, primarily in Zimbabwe and Togo,” Roach said.

Apart from its Zimbabwe expansion through the planned tungsten mine, Premier African Minerals reported last month that three of its Southern Togo exploration permits for a project covering phosphates, uranium and rare earth mineral deposits had been renewed another two years.The company, a multi-commodity natural resource company, has mineral projects located in Western and Southern Africa.
