Atna Resources has completed construction of the secondary access passage into its Pinson underground gold mine situated in Humboldt County, Nevada, US which will enable the company to continue development of spiral access into the mine.

Work has started on this spiral, facilitating development of ore mining areas with the goal of achieving gold ore production in the fourth quarter of 2012.

The firm has received a notice from the Nevada Division of Environmental Protection that modification to its water pollution control permit to increase to a large scale facility producing up to 400,000 tons of ore annually is administratively complete.

It also obtained the Class II Air Quality Operating Permit from the Nevada Division’s agency, which covers the operation of an ore crushing facility, a crusher facility for aggregate for backfill, a shotcrete plant, a backfill plant and an assay laboratory.

The company has constructed an underground chamber for installation of the primary ventilation fans and air door lock as part of the secondary access.

Atna Resources CEO and president James Hesketh said the development of Pinson is going smoothly and advancing toward its goal of gold production in the fourth quarter of this year.

"We are encouraged by the swift response of the Nevada Division of Environmental Protection to our permit modification request and anticipate approximately 4 to 6 months for final approval of the modification," Hesketh said.
