LME zinc appears to be slowly building base at current levels, supported by declining stocks at LME warehouses, down 4,100 tons last week, says Standard Bank. LME 3-month zinc last quoted at $3,660/ton, untraded in Asia, down $10 on London Friday PM kerb. Adds next key technical resistance at $3,800, break above would set up test of $4,000, last traded at that level Jan. 5. JPMorgan also says break above $3,800-$4,000 possible in 2Q due to zinc being oversold in 1Q, but carry through unlikely as supply to grow +11% in 2007.
