LME 3-month lead top-heavy around $1,880-$1,900/ton, likely to drift lower in coming sessions, possibly testing immediate support around $1,780-$1,800, says HK-based trader. Notes profit taking overnight suggests lead's gains on Monday likely overdone; but adds a longer-than-expected disruption at Magellan lead mine in Western Australia could trigger another rally. LME 3-month lead last quoted at $1,885.15/ton, untraded in Asia, +$10.15 on London PM kerb after falling $69 overnight.
