Ever since Friday's New York Times report saying the US State Department assigned an important environmental impact study of the Keystone XL pipeline to Cardno Entrix, a company with financial ties to the pipeline operator TransCanada, in contravention of federal law, opponents of the project have shifted the focus of their opposition to allegations of conflict of interest and corruption. Two prominent names on the political left and in the green movement Naomi Klein and Bill McKibben put it most bluntly: Obama's plan to transport oil from Canada to the Gulf Coast reeks of cronyism and it is quite possibly the biggest potential scandal of the Obama years. TransCanada officials meanwhile appear to have been caught off guard by the vociferous protests that weeks of Keystone hearings that ended on Friday have elicited, pointing out that TransCanada won approval for a similar pipeline three years ago with little opposition.

The International Center for Settlement of Investment Disputes has advised Crystallex International Corp. that proceedings in its $3.8 billion case against Venezuela for nationalizing gold-mining assets has begun. The Toronto-listed company's main asset is its interest in the Las Cristinas gold project located in Bolivar State, Venezuela. Crystallex also holds interests in the Tomi and La Victoria mines in Venezuela and on Friday closed down 70% from its 52-week high. The stock was delisted in from the New York Stock Exchange earlier this year. Toronto-listed Rusoro is the only large producing gold miner operating in Venezuela and the country does not feature in the top 20 global gold producing states.

The Wall Street Journal reports Mongolia is relaunching talks with international miners on developing the western block of Tavan Tolgoi in the South Gobi desert, the world’s largest deposit of high-quality coking coal used in steelmaking. Mongolia's National Security Council rejected a deal struck with US giant Peabody Energy, China's Shenhua and a Russian-Mongolian consortium mid-September, just two months after they were announced as winners. At the time losing bidders from Brazil, India and South Korea raised serious concerns and Japan went so far as to call the bidding process 'extremely regrettable'. Mongolia still hopes to privatize its Erdenes Tavan Tolgoi coal-mining company which controls the remainder of the 6 billion tonne resource for upwards of $3 billion next year.

News reports on Saturday say Rio Tinto's Zimbabwe subsidiary Murowa Diamonds has ceded 51% of its equity to comply with a new law that requires Zimbabweans to own the majority of foreign companies. Rio Tinto says on its website it has completed a feasibility study and received environmental go-ahead to expand Murowa production 8-fold at a cost of $200 million. Saturday's report cast serious doubts on whether the investment, which requires foreign capital, would now be made. It appeared in recent weeks as if Zimbabwe was soft-pedalling the indigenization laws, but Rio Tinto's capitulation has now put pressure on Impala Platinum, struggling to hold onto its $20 billion worth of reserves in the country.

Tucson Sentinel reports the Painted Desert of northern Arizona holds hundreds of million years of history, from fossils of dinosaur ancestors to ancient Native American dwellings, but Petrified Forest National Park and the land around it also sit on as much as 2.5 billion tons of potash. The US Congress approved expansion in 2004, authorizing the park to purchase land from willing sellers. The park added the first 26,000 acres in September, but that purchase didn’t include the mineral rights because of a lack of funds.The old and new boundaries of the park are over approximately 50% of the Holbrook basin potash deposits and three companies – Passport Potash, American West Potash and HNZ Potash – currently are drilling test holes inside and outside the park to establish the depth and quality of the deposits.

Does gold's precipitous $300 drop in September represent a fundamental market shift? It is hard to argue with this statement: "Global stock markets are volatile, central banks have not regained credibility, inflation is still a concern, and trust in the markets has not been restored. Yet gold continues to fall... Gold has lost its shine."

Workers at Freeport's Grasberg – one of the world's largest gold and copper mines – in the remote Indonesian province of West Papua vowed Friday to paralyse production, as their strike over pay enters its second month. About 12,000 of Freeport's 23,000 Indonesian workers have joined the strike that started on Sept. 15 and on Friday Freeport said some workers have returned, putting it in a position to increase mining and milling output. The gulf between the the two parties are so wide that chances of a settlement appear remote – Freeport has offered a 25% increase on wages while the union wants the current minimum rate of $1.50 an hour raised more than 8-fold.

IDEX Online News reports the rough diamond market is in a rut and demand for rough is so limited, that traders are not buying goods, even if offered at 12 or even 13 percent below what DTC's roughly 80 selected clients – called Sightholders – paid for at last week's Sight. Traders cannot move it, and manufacturers claim that with the current decline in polished prices they will lose money. IDEX says from a low cost supplier, DTC – the rough diamond sales and distribution arm of De Beers – has ascended to the pricier side of the list, alongside Russia's Alrosa. Many lots also went unsold at BHP Billiton's latest tender and Diamdel's auction, with bids falling short of the reserve prices.

Reuters reports copper rose to its highest in nearly a week on Thursday to close at $7,225/tonne on the LME up from Wednesday's close of $6,820 as US data hinted at an improvement in the labour market and European policymakers' comments on dealing with Greece's debt crisis calmed nerves. Copper's strong gains comes at a time when some 5,000 merchants are gathering in the British capital for London Metal Exchange week, an annual event during which supply contracts are discussed. On Monday the red metal fell to 14-month low.

AFP reports a blue-and-white Ming vase fetched nearly $22 million in Hong Kong on Wednesday, setting a new record at auction for porcelain from the 15th century Chinese dynasty. The vase went for more than double the lower pre-sale estimate, but at Sotheby's jewels and jadeite auction held at the same time the 9.27-carat Golconda Pink diamond with an estimate of $13 million – $19 million went unsold. Hong Kong is now the world's third-largest auction centre after New York and London, thanks to China's rapidly growing number of millionaires.
