BOZEMAN, Mont. -

A mining company planning to build a copper mine near a Smith River tributary has resubmitted its application after state environmental officials said the previous version was insufficient.
   
The Bozeman Daily Chronicle reports that Tintina Resources Inc. resent its application to the Montana Department of Environmental Quality after the previous version was rejected six months ago.
   
The mine would be located on private land about a mile from Sheep Creek, which feeds into the popular Smith River.
   
Conservationists and fly-fishing organizations are concerned the mine will harm the river and its trout fishery.
   
Tintina CEO John Shanahan said in a news release that the new application is more comprehensive.
   
DEQ public policy director Kristi Ponozzo says the agency will review the new application over the next 30 days and decide whether all issues have been resolved.
