Copper, nickel prices gain on session

Metals prices were mixed on Monday, with gold falling 0.3 percent to $689.10 per troy ounce. Palladium was lower as well as it dropped 0.5 percent to $380 per troy ounce. Platinum, however, was 1.5 percent higher on the session to $1,315 per troy ounce after going as high as $1,330 per troy ounce during the session.

Among base metals, tin was steady at $13,800 per tonne on the news that nine Indonesian smelters have received government export permits after those permissions were pulled last year.

Copper prices were 0.7 percent higher to $8,007.5 per tonne after dropping to as low as $7,850 per tonne in earlier trade. The declines came after worries about supply disruptions in Indonesia faded and gains were helped by news of record refined copper imports in China in March.

Nickel prices added 1.4 percent to $49,400 per tonne as inventories remained very low in London Metal Exchange warehouses despite some evidence of off-market increases in inventories.
