April 28 (Reuters) - Precious metals miner Hecla Mining Co (HL.N) posted a first-quarter profit that beat Wall Street view partly aided by higher prices and lower operating costs per ton.
Hecla also reaffirmed its previous full-year production outlook of 10 to 11 million ounces of silver with cash costs in the range of $1.90-$2.25 per ounce.
Net income for the first quarter was $21.8 million, or 7 cents a share, compared with $7.3 million, or 2 cents a share, a year ago.
The company, which primarily mines processes and explores for silver and gold in the United States and Mexico, saw revenue rise 46 percent to $79.9 million.
Analysts on average expected the company to earn 3 cents a share, on revenue of $81.9 million, according to Thomson Reuters I/B/E/S.
The company said the first-quarter saw average prices for all metals rise from the prior year period, adding unit operating costs for mining and milling dropped 3 percent to $67.54 a ton during the period.
