Nickel

IMX Resources Limited (ASX:IXR) is pleased to announce that initial metallurgical testwork has confirmed that high grade nickel concentrates with high recoveries can be produced from the multiple Ntaka Hill ore zones at the Nachingwea Ni-Cu joint venture in Tanzania. The Project is a joint venture between IMX Resources Limited (25%) and Continental Nickel Limited (75%).

Preliminary estimates from Metals Economics Group’s (MEG) Corporate Exploration Strategies (CES) study indicate that 2011 nonferrous exploration budgets will exceed $17 billion for expenditures related to precious and base metals, diamonds, uranium, and some industrial minerals.

Canadian Arrow Mines could soon be mining nickel again at its Kelex and Alexo mines near Timmins, Ontario. The Toronto-listed company (TSX-V:CRO) has received regulatory approvals to resume production with a small-tonnage, open-pit operation at the Kelex Central West pit, which was exposed, but only superficially mined, before suspension of production in 2005 due to nickel prices falling below US$5/lb.

The US Geological Survey (USGS) said on Wednesday it estimated there were at least one-million tons of rare earth elements contained in resources in Afghanistan’s restive Helmand province.

The Australian quotes a Rio Tinto spokesman on Wednesday saying the discovery of a species of freshwater crab and a never before recorded shrimp near its Weipa mine would not be threatened by a planned bauxite expansion, but environmental protesters could still scupper the $900 million project. Rio Tinto, the world's number two miner, found a total of six species of crustacean including the new crab, which is about the size of a quarter, as part of its environmental impact study. It is now up to Australia state and federal governments to assess the findings.

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. Surprisingly rare earths used in green technology and defence do not top the list but comes in at number five. Antimony, extracted mainly from stibnite (pictured), widely used for fireproofing is most at risk. 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.

A dispute in the north of New Caledonia has stopped the export of nickel ore from the SMSP site to its South Korean partner, Posco. Members of the Kaala-Gomen tribe claim that the United Nations Declaration on the Rights of Indigenous Peoples provides for them to have a share of the profit drawn from mining.

Mining investments could reach $2.8 billion in the Philippines this year if Chinese investors proceed with plans to jointly develop mining projects in the country, a senior mining official said Tuesday. There is a good chance that an initial target of $1.4 billion could be doubled if Chinese investors follow through in the last quarter on investments they have expressed interest in, Mines and Geosciences Bureau director Leo Jasareno said.

Reuters reports prices of most rare earth elements – used in consumer electronics, defence and green energy industries – have risen since Wednesday after of local government crackdown on mining, with three major producers slated for closure. The news follows an announcement from the EU that it is building a stockpile of a variety of REEs and that a high-level meeting of officials from Europe, the US and Japan will take place in Washington early next month to discuss supply security. The price of some REEs such as samarium oxide used in jet fighter electrical systems has increased 25-fold in just three years.
