HONG KONG, March 31 (Reuters) - Mining firm Green Global Resources (0061.HK: Quote, Profile, Research) will start iron ore production in the second half of the year in Mongolia, despite disturbances caused by severe weather there, its chairman said on Wednesday.

Severe winter weather in Mongolia has killed millions of animals, blocked roads and affected exploration and mining activities in some areas in the country.

"We're about two weeks behind schedule now but we are working hard to catch up," Joseph King, newly appointed chairman of the agribusiness-turned-mining company, told Reuters on the sidelines of a mining conference in Hong Kong. "That's important to us and we are racing against the time.

Green Global will change its name to North Asia Resources Holdings Ltd following a reverse takeover last year amid a raft of Mongolian mining firms flocking to Hong Kong to list.

It has invested in an iron ore mine in Dundgobi aimag, about 270 km southwest of Mongolia's capital Ulaanbaatar, with an estimated 148.9 million tonnes of iron resources and 174,000 tonnes of copper resources in the First Mine Area alone, which accounts for about 8.33 percent of the total mine area.
