Niblack Joint Venture Receives Priority Permitting Approval from US Forest Service

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.

Instrument 43-101, is supervising the exploration and quality assurance and
quality control programs on behalf of Niblack and has reviewed the content of
