Rare Earth Metals: Tantalum sector desperate for new resources TNR.v, CZX.v, AVL.to, RES.v, CCE.v, GOOG, AAPL, SNE, RIMM, BYDDY, NSANY, RNO, BMW, DIA,

Key point summary:
1. Samples at Mavis & Forgan Lake have confirmed high grade Li2O and the presence of rare metals -- grab samples up to 3.14% Li2O.
2. Other Rare Metals (Tantalum) over limit samples are pending
3. Phase 2 follow-up underway"

"Tantalum (formerly called tantalium), it is originated from Latin Tantalus sometimes called Tantale or Tantal Sonderwerkstoffe. Tantalum has a melting point of 2996°C and a density of 16.65 gm/cc, it is one of refractory metals (the most extensively used of these metals are tungsten, tantalum, molybdenum and columbium or niobium), most sheet-metal fabrication of tantalum can be welded to itself and to certain other metals by resistance welding, tungsten inert-gas (TIG) welding, and to itself by inert-gas arc welding. Electron-beam welding can also be used, particularly for joining to other metals. However, surfaces that are heated above 315°C during welding must be protected with an inert gas to prevent embrittlement.
Tantalum and tantalum alloys are midway between tungsten and molybdenum in density and melting points. Tantalum can be worked easily at room temperature. Tantalum's corrosion resistance is excellent in most acids and caustics as glass . Pure tantalum recrystallizes at approximately 2200°F (1204°C).
Principal applications for tantalum are in capacitor anodes, filaments, gettering devices, chemical-process equipment, and high-temperature aerospace engine components. Tantalum offers excellent "gettering" properties, making it popular in vacuum tubes to absorb products of out-gassing upon heat up of the tube components. It is also used to getter potential contaminants of niobium and its alloys as well as titanium during vacuum heat treating operations. Tantalum also provides good thermal conductivity that, combined with its corrosion resistance, has made it the ideal choice for heat exchangers for acid processing equipment. It is superior to the nickel-based alloys in both these categories.Tantalum also develops a stable oxide (Tantalum Pentoxide) that is useful in electronics industry applications."



SUPPLY CRUNCH
Mineweb Tantalum sector desperate for new resources
Analysts estimate stock piles could run dry in as little as 3 years

WASHINGTON (Reuters) -
A severe supply crunch has hit the tantalum industry, and stockpiles of the metal used primarily in consumer electronic products could run dry in as little as three years, an industry analyst said on Tuesday.
"The industry at the moment is living on stocks. Late last year it was estimated that there was enough tantalum in the supply chain to last for two years. That was last year ... that will run out by 2012," said Patrick Stratton BA, senior analyst with Roskill Information Services Ltd. during a panel discussion titled, The 'Alternative Energy' Metals at the Managing Supply Chain Risks for Critical & Strategic Metals conference in Washington, D.C.
Stratton said the industry's problems were largely brought on by an unprecedented spike in the spot market price in 2000 after similar supply fears caused many nervous dealers to lock themselves into long-term contracts at very high market prices.
"They (tantalum capacitor manufacturers) paid for it dearly with inventory write-downs and future inventory write-downs," Stratton said. After a period of relative stability in the market, he said, everything "fell off of a cliff" in 2008, as the economic downturn put the brakes on consumer demand.
Many companies suspended production, including Australia's Talison Minerals, which provided about a third of the world's tantalum supply. Others included Noventa's Mozambique mine and Canada's Tanco mine.
Talison plans to reactivate its Wodgina mine in mid-2010.
"We have a situation now where primary production of tantalum is limited to material coming out of Brazil, some production coming out of Africa, some Chinese material, and that is about it," Stratton said.
He saw only two real possibilities for new acceptable and ethical sources of tantalum, and they were both in Canada.
One was the Blue River Project in British Columbia, owned by Commerce Resources Corp (CCE.V), which was expected to be up and running in 2011.
Since 1990, tantalum's demand growth rate is about 5% per year. The price of tantalite, used to make tantalum metal, has been trading south of $40 a lb in the third quarter of 2009.
"A good question to ask is, 'what is the downstream industry more afraid of ... the price of tantalum or not being able to get hold of any tantalum?" Stratton asked.
"The second part of that is a very real possibility if something does not happen very soon." (Editing by David Gregorio)"

You are quite correct about the coming tantalum shortage which will hit late 2011.

The comment by Mr Stratton is quite misleading as the Canadian tantalum deposits, including those held by Commerce Resources, are low grade and at a very early stage of development only, having small JORC Code Indicated and Inferred Resources and no Measured Resources. No Canadian miner holds JORC Code Mining Reserves of tantalum. No project in Canada has completed a Bankable Feasibility Study or the required Environmental Impact Assessment. These facts dictate that if proven viable by way of a BFS, Canadian projects will come on line in about 4 years, particularly as winter access will cause a degree of delay.

The next tantalum project to commence will undoubtedly be the 44.5 million tonne Abu Dabbab tantalum-tin project held by Gippsland Limited through its joint venture company Tantalum Egypt JSC.
This project contains world scale Resources and most importantly, substantial Mining Reserves.
A detailed Abu Dabbab Bankable Feasibility Study and an Environmental Impact Assessment has been concluded, with construction of the plant imminent.
Abu Dabbab will commence production at 650,000 – 720,000 pounds of Ta2O5 which will place it as the world’s largest single source of tantalum feedstock with production commencing in 2012.
In view of the coming shortfall, plans are already being set in place to expand production to >1,000,000 pounds of Ta2O5 pa.
total exactly due to rounding

In addition to Abu Dabbab, Gippsland also holds the nearby Nuweibi tantalum deposit which contains a JORC Code Resource of 98 million tonnes.

Talison Minerals to restart Wodgina tantalum mine (25 September 2009)
Roskill and others made comments to the effect that Talison Minerals will recommence tantalum production in 2010 however Talison subsequently denied this stating that they may recommence production if tantalum prices increase to a level at which the material could be produced profitably. In the mean time, the loss-making Talison Wodgina mine will remain closed.
