Copper edges higher on Chilean mine strike and supply concerns

London Metal Exchange benchmark copper futures rose 0.4% to settle at $14,475.50 a metric ton due to a strike at Antofagasta's Centinela mine in Chile.

Two unions at the Centinela mine began a walkout that is expected to impact output within two weeks, while Escondida mine supervisors continued wage talks.

Gains were constrained by a stronger dollar, a pullback in US stocks, and Treasury yields holding near 2002 highs.
