April 23 (Reuters) - Newmont Mining Corp, the world's No. 2 gold producer, reported an 89 percent rise in first-quarter adjusted profit on Thursday, helped by lower costs and higher copper production.
Adjusted net income, which excludes one-time items such as non-cash write downs, rose to $229 million, or 46 cents a share, in the quarter ended March 31, from $121 million, or 24 cents a share, a year earlier.
Sales rose 11.8 percent to $1.97 billion. (Reporting by Susan Taylor in Toronto and Manya Venkatesh in Bengaluru)
