SYDNEY, June 22 (Reuters) - London copper held on to hefty overnight gains, spurred on by data showing the metals's shift to global a supply deficit.
The global world refined copper market showed a 5,000 tonne deficit in March, compared with a 102,000 tonne surplus in February, industry data released this week showed.
* LME COPPER: Three-month copper on the London Metal Exchange was flat at $5,745 a tonne by 0100 GMT after climbing 1.6 percent overnight.
*ShFE COPPER: The most-traded copper contract on the Shanghai Futures Exchange opened 1.32 percent higher at 46,100 yuan ($6,752.11)a tonne.
* POLISH COPPER: Shareholders in Polish state-run copper producer <KGHM KGH.WA> on Wednesday approved a dividend payout of 1 zlotys per share, in line with the management board's proposal.
ZINC: Zinc was mostly flat at $2,643 a tonne after ending 3.3 percent higher overnight, bolstered by a weaker dollar and concerns over tightening supplies, with LME stocks at their lowest since January 2009 <MZN-STOCKS>. ShFE zinc was up 2.9 percent.
* CHINA STEEL: Shanghai steel futures fell nearly 2 percent on Wednesday, slipping for a second straight day on worries that continued rain in many parts of China would limit short-term demand in the world's biggest steel user.
* NICKEL DEFICIT SLIMS: A global deficit of refined nickel narrowed in April after a jump in refined metal output from Indonesia and China, data from the International Nickel Study Group showed on Thursday.
* DOLLAR SLIPPAGE: The dollar slipped from a one-month peak against a basket of currencies on Wednesday, as losses on Wall Street stocks spurred some traders to book profits on gains tied to expectations of possibly another U.S. interest rate increase later this year.
