LONDON, April 5 (Reuters) - Copper rose 2 percent on Wednesday, reflecting strength across base metals following upbeat jobs data from the United States and the return of Chinese buyers after a two-day break.
A one percent drop in copper prices since China, the world's biggest consumer of industrial metals, closed for its latest holiday tempted buyers.
"Prices got a boost with the publication of the latest ADP (jobs) numbers," Commerzbank analyst Carsten Menke said. "It seems to have been enough to push the optimism among market participants higher."
Copper came under pressure last week from indications that a number of production outages that had driven prices sharply higher in February were coming to an end.
A jump in oil prices to their highest in a month also boosted a broader appetite for commodities, analysts said.
* LME COPPER: Three-month copper on the London Metal Exchange closed up 2 percent at $5,895 a tonne. A move back through resistance at the 100-day moving average at $5,790 improved its technical picture, traders said.

* NICKEL, ZINC: LME nickel closed up 3.2 percent at $10,295 a tonne, driven higher by gains in the steel sector after a cyclone in Australia damaged transport routes for coking coal. Zinc ended the day at $2,778 a tonne, up 1.5 percent.
* ZINC SPREAD: The discount of LME cash zinc to the three-month contract CMZN0-3 moved to $27.25 a tonne, its widest since October 2015, indicating adequate supply of refined metal in the market.
* FREEPORT: Indonesia's Secretary General for the Energy Ministry, Teguh Pamuji, said on Tuesday that Freeport McMoRan would receive a temporary "special mining permit" to allow its operations to continue and exports to resume while discussions on longer-term issues continued.
* PERU: Peru will likely gradually increase its copper production to 3.1 million tonnes in 2021 from an annual 2.35 million tonnes expected for both this year and next, the country's energy and mines minister told the CRU World Copper Conference in Chile.
* CESCO: Southern Copper should share more of its profits with workers in Peru to avoid an indefinite strike at its Toquepala and Cuajone mines starting on April 10, a union leader said on Tuesday.
* COLLAHUASI: The Collahuasi copper mine in Chile, a joint venture between Anglo American and Glencore, expects 2017 output to beat last year's, and could ramp up production that was frozen in 2015 if the price of copper keeps rising, the mine's chief executive told Reuters.
