Niblack Joint Venture Receives Priority Permitting Approval from US Forest Service

EDMONTON, ALBERTA -- (Marketwire) -- 08/22/11 -- Niblack Mineral Development Inc. ('Niblack' or the 'Company') (TSX VENTURE: NIB) and joint venture partner Heatherdale Resources Ltd. (Heatherdale) (TSX VENTURE: HTR) are pleased to report that on August 16, 2011 the US Forest Service Alaska Regional Forester Beth Pendleton announced that exploration drilling at the Niblack Project has been approved to go forward. The permitting approval allows the joint venture to drill test several high priority exploration targets located on federal lands designated as inventoried roadless area. This will complement and significantly enhance the ongoing exploration program at the Niblack Project.

'Today, Forest Service Chief Tom Tidwell approved geotechnical and exploration drilling in inventoried roadless areas for the Greens Creek Mine and the Niblack Mine exploration projects,' said Pendleton. 'This approval will allow Greens Creek to continue the expansion of its tailings site and Niblack to continue its exploration.'

'These two projects will help employ Alaskans on important projects while providing crucial environmental safeguards,' said Harris Sherman, Undersecretary for Natural Resources and the Environment at the US Department of Agriculture. 'Both the Niblack and Greens Creek projects will have minimal footprints -- less than an acre apiece -- with the potential for substantial boosts to local economies.'

The joint venture would like to acknowledge the combined efforts of the Alaska Governor, Congressional delegation, the USDA and the local USFS in obtaining these approvals. We particularly appreciate the strong show of support from Governor Parnell and from Senator Mark Begich. This priority permitting will allow the technical team to test high priority targets that can be best accessed by helicopter supported drilling before the end of the field season.

There are currently two underground drills operating at the Niblack Project. The surface drilling program initiated in late May to focus on targets accessible from patented mining claims on the property was put on hiatus. The current approval from the US Forest Service means that the drill program will resume in Q3/Q4.
