Base metal prices were generally strong with zinc the stand-out performer, rising a colossal 27.7% over the month (in US$ terms). The uranium price hit a new high of $60/lb at the end of October following the flooding of Cameco's Cigar Lake development project. This underground operation had been due to commence production in 2008, representing approximately 10% of global annual mine supply. The flood has meant the project could now be delayed by up to three years which has significantly increased the tightness in the uranium market in the medium term. Rio Tinto increased its current share buyback programme by $3 billion, bringing it to a total of $7 billion. It also announced that it had formed a strategic partnership with Ivanhoe Mines to jointly develop and operate Ivanhoe's Oyu Tolgoi copper-gold deposit in Mongolia. Oyu Tolgoi is one of the largest undeveloped copper deposits in the world. Rio Tinto's share price rose by 14.4% over the month (in Sterling terms). Markets continue to be volatile; however supply and demand fundamentals for the mining industry remain robust. Supply side disruptions continue to impact the market in 2006, the repercussions of which should support strong metal prices going forward. Higher commodity prices have led to another round of spectacular results from the mining industry and this has meant many of the Company's holdings are translating their strong balance sheets and high cash flows into higher dividends and increased share buybacks. These compelling fundamentals will mean there is the continued possibility of further corporate activity as mining companies seek to grow quickly and cost effectively.
