Antimony supply at top of risk list

I just read in a news story at that the British Geological Survey (BGS) on Wednesday published the latest list of the 52 elements, minerals and metals most at risk of supply disruption because global production is concentrated in a few countries, many with unstable governments. Link to full story

It is surprising that the BGS places Antimony at the top of it's published (latest) list of the 52 elements, minerals and metals most at risk of supply disruption. Rare earths used in green technology and defence technologies do not top the list but comes in at number five.

Quote from story

The platinum group metals (auto catalysts) hold the second spot while niobium used in touch screens and scanners and tungsten for cutting tools are also at risk of supply disruption as a result of increased competition among the world’s growing economies, political instability, resource nationalism, along with events such as strikes and accidents. China is the number one producer of 50% of the 52 chemicals on the list and produces 75% of the world’s antimony.

In Newfoundland the Beaver Brook Antimony Mine was reactivated in 2008. In October of 2009, Hunan Nonferrous Metals Corporation (HNC), the largest antimony company in the world, acquired 100% equity of Beaver Brook Antimony Mine Inc. At the end of 2009, China Minmetals Corporation, China’s biggest metal trader, acquired 51% equity of Hunan Holdings Group (HNG), the state-owned parent of HNC.  Link to Beaver Creek Mine Profile

The reasoning behind the Chinese investment in the mine and the company holding it becomes clearer and looks like a strategic move, when we look at the BGS list.  

Looks like Antimony is could be another good mineral to prospect for.

Happy Prospecting!

Gold From Space

Found an interesting news story at BBC News Science and Environment written by that gold was delivered by meteorites long after their formation.

Their results are published in Nature.
While the Earth was forming, iron sank to the centre of the planet, forming the core.
Any precious metals in the planetary mix would have gone with this iron and concentrated in the core, leaving the mantle devoid of elements such as gold, platinum, and osmium.

But this is not what we observe. In fact, the silicate mantle has up to 1,000 times more gold than anticipated.

Several reasons for this enrichment were proposed in the past, including delivery by meteorites, although until now it has not been possible to prove. 

By measuring isotopes in rocks that are nearly four billion years old from Greenland, the team has managed to date the gold delivery, and to relate it to an event known as the "terminal bombardment".

The story also goes on to say that the scientists have used a totally different mineral to preform their experiments and  reach their conclusions that mineral in Tungsten.

"The proportions of gold and other precious metals are difficult to measure because they concentrate into nuggets, and we need to analyse a lot of rocks to get meaningful data." said lead researcher Dr Matthias Willbold.

They have therefore developed a way of telling this remarkable story of gold's extraterrestrial origin using a completely different element - Tungsten.

More on this story

The study is very interesting I wonder if it would be worth while do a little prospecting at Tungsten occurrences and perhaps do a few assays for gold in those samples?

The whole story about gold and other minerals being "deposited" in younger rocks of the earth as the result of being  impacted with 20 billion billion tonnes of asteroid material, is certainly interesting and intriguing.

May dust off some data on local Tungsten deposits. After all, information is the prospectors best friend!

Happy Prospecting!

Miners Holding - Markets Down Post Labour Day

TORONTO-NEW YORK - The Toronto Stock Exchange pared early triple-digit losses but still closed lower Tuesday as North American traders returned from the Labour Day holiday focused on persistent concerns about a global slowdown.

The S&P/TSX composite index finished the day down 83.87 points at 12,518.54 after falling more than 200 points earlier in the session.

The TSX Venture Exchange fell 20.54 points to 1,789.82.
Wall Street markets also lost ground with the Dow Jones industrial average down 100.96 points at 11,139.3. The Dow had been down more than 300 points in morning trading but regained much of the lost ground after European markets closed.

The Nasdaq index fell 6.5 points to 2,473.83 and the S&P 500 was down 8.73 points at 1,165.24.
