Niblack Joint Venture Continues Successful Drilling at Niblack
31 October 2011 - 11:30PM
Marketwired
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

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.
