Heatherdale Continues Successful Drilling At Niblack
October 31, 2011, Vancouver, BC -- Heatherdale Resources Ltd. ("Heatherdale" or the "Company") (TSXV:HTR) announces additional positive results 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.
Hole U131 -- 26.8 feet of 4.66% Cu; 13.57 g/t Au; 15.26% Zn; and 302 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," stated Pat Smith, President and CEO. "Drill core collected from this program will also be utilized to advance our 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 that will be completed shortly."
Smith added, "I am extremely pleased with the results of the 10 exploration holes -- three of which were drilled from underground and seven from surface. These holes are confirming the excellent potential of the stratigraphy that hosts mineralization at Niblack, and have validated the application of the new geological interpretation."
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 Heatherdale website at http://www.heatherdaleresources.com/hdr/Sections_Plans.asp.

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.
Niblack's location at tidewater on Prince of Wales Island in southeast Alaska presents a number of project benefits, including year-round marine access, a well-trained labour force, a mature supply and service sector, proximity to Asian markets, and the support of community and Alaska Native corporation partners. The project is located 27 miles (44 kilometres) from Ketchikan, a community of 8,000 people with important services to support project development, including a deep water port and international airport. The State's burgeoning minerals industry also enjoys a competitive tax regime and stable, predictable permitting and regulatory oversight coordinated by the Alaska Department of Natural Resources', 'Large Mine Permitting Team'. For reference, Hecla's Greens Creek, a 2,100-ton per day underground massive sulphide mine, operates 225 miles (370 kilometres) to the northwest of Niblack on Admiralty Island.

On behalf of the Board of Directors
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.
