Even CS researchers who can be viewed as very cautious see the metals to be a good investment for 2010. Where they predict Au and Ag to only go up slightly from where they are now, they suggest that some of the base metal will gain.
Here are some numbers:
Zinc: from around 1920 ($/t) to 2100-2200
Lead: from around 2150 ($/t) to 2200-2300
Nickel: from around 18130 ($/t) to 21000-22000
Copper: from around 6100 ($/t) to 7300-7500
Some of that could be good for ECU, too.
Cheers,
