LONDON, Nov 6 - Spot uranium prices rose to $90 per pound this week, according to the Ux Consulting website, a leading publisher of uranium prices and forecasts. Setbacks of uranium start-up projects in Kazakhstan, due to a temporary shortage of sulphuric acid, bolstered the price. "It will go even higher, speculative money is coming back into the market," analyst Eugen Weinberg at Commerzbank said. Weinberg said prices would trade above $100 in just a few weeks and reach $120 in the coming months with the weaker dollar also supporting the uranium cash price.
