Niblack Joint Venture Continues Successful Drilling at Niblack

Niblack Mineral Development Inc. (TSX VENTURE:NIB) or "the company" announces
additional positive results completed by joint venture partner Heatherdale
Resources Ltd. (TSX VENTURE:HTR) from delineation and exploration drill holes
completed during the 2011 spring and summer program at the Niblack volcanogenic
massive sulphide (VMS) project in southeast Alaska. Significant intersections of
copper, gold, zinc and silver were encountered in several of the holes.




Highlights include:                                                         
  Hole U131 - 26.8 feet of 4.66% Cu; 13.57 g/t Au; 15.26% Zn; and 302 g/t Ag
  Hole U132 - 44.6 feet of 2.54% Cu; 5.54 g/t Au; 10.96% Zn; and 126 g/t Ag 
  Hole U136 - 35.7 feet of 4.60% Cu; 5.68 g/t Au; 10.00% Zn; and 141 g/t Ag 



Three drill rigs were utilized to complete the 21,300 feet of drilling described
in this news release. Two underground drill rigs were active continuously
throughout the program, to explore for and delineate resources in the Lookout
and Trio Zones. Several of the holes were directed toward collection of samples
for metallurgical testwork. In addition in May and June 2011, a
helicopter-supported surface drill rig was added to the program to test several
of the compelling exploration targets in the area of the historic Niblack Mine,
as well as the Trio and Broadgage zones.


The 10 delineation holes drilled from underground in the Lookout Zone have
reaffirmed the robustness of the mineralization at Niblack. Drill core collected
from this program will also be utilized to advance understanding of the project
metallurgy, and support engineering studies toward completion of a
Prefeasibility Study. The additional data and information received from these
drill holes will be incorporated into a new resource estimate.


Three exploration holes drilled from underground firmly established the
continuity of the mineralization hosting felsic horizon between the Lookout and
Trio zones as well as to the northwest of the Lookout Zone, and have also
provided positive indicators for the next stage of drilling in these areas.


Of the seven surface exploration holes reported here, six tested the felsic
horizon in the Trio-Broadgage area and one hole targeted the area proximal to
the historic Niblack Mine. The detailed geologic model has been validated from
this drilling and six of the seven holes intersected sulphide mineralization
that will guide the next round of exploration drilling. The mineralization
encountered in hole S148, which intersected 22 feet grading 0.53% copper and
1.54 g/t gold, has provided important information about the plunge direction of
the mineralization in the Trio zone.


Important intersections from these 20 new holes are presented in the Niblack
Assay Table below. Assays from these as well as the first 100 holes drilled
(released previously) and a drill hole location section are available on the
Niblack website at http://niblack.com/project_areas/united_states/niblack/.

Holes denoted with a "U" above were drilled from stations spaced along an adit
and are drilled with a range of different azimuths and dips. Holes denoted with
an "S" were drilled from surface. Underground drilling proceeded in fan patterns
from drill stations. True widths of intersections have not yet been accurately
established.

On behalf of the Board

Niblack Mineral Development Inc.

John Williamson, President, CEO & Director

Sample preparation and analysis for the Niblack project is done at ISO 9001
accredited ALS Chemex laboratories in Vancouver, BC. All samples are assayed for
gold by 30 g fire assay fusion with Atomic Absorption Spectroscopy (AAS) finish.
Copper, silver, zinc, lead and 29 additional elements are determined for all
samples by four acid digestion, followed by ICP-AES finish. All over-limit
copper, zinc or lead results (greater than 10%) and all over-limit silver
results (greater than 200 grams per tonne) are re-assayed by high grade single
element four acid digestion ICP-AES or AAS analysis. As part of a comprehensive
QA/QC program, one standard is inserted into the sample stream in each group of
20 samples, as well as one or more field blanks in each analytical batch. One
sample in each group of 20 is a duplicate, which is analyzed by Acme Analytical
Laboratories in Vancouver.


This release includes certain statements that may be deemed "forward-looking

developments that the company expects are forward looking statements. Although
the company believes the expectations expressed in such forward-looking
statements are based on reasonable assumptions, such statements are not
guarantees of future performance and actual results or developments may differ
materially from those in the forward-looking statements. Factors that could
cause actual results to differ materially from those in forward-looking
statements include market prices, exploitation and exploration successes,
continuity of mineralization, uncertainties related to the ability to obtain
necessary permits, licenses and title and delays due to third party opposition,
changes in government policies regarding mining and natural resource exploration
and exploitation, and continued availability of capital and financing, and
general economic, market or business conditions. Investors are cautioned that
