Copper rising despite production strikes

In the commodities markets on Tuesday, gold lost 1 percent to close at $422.50/$423.20 per troy ounce, near a 3 ½-week low, while 3-month copper gained $22 to $3,262 per tonne.

The advance in copper prices was not higher because of the strength of the dollar and expected output rises later in the year.

However, availability is expected to remain limited, even though production capacity is increasing, due to strikes in the US and Chile.
