Heatherdale Surface Drilling Extends Trio Zone At Niblack

 November 29, 2012, Vancouver, BC -- Heatherdale Resources Ltd. ("Heatherdale" or the "Company") (TSXV:HTR) announces positive results from drill holes completed during the 2012 surface drill program targeting resource expansion of the Trio deposit. This drilling confirms important extensions to the existing Trio resource estimate published in November 2011 at similar grades and demonstrates that the zones of mineralization continue down dip. This mineralization that is still open in three directions will be prioritized for drilling in 2013. Trio is one of six known volcanogenic massive sulphide (VMS) zones at its Niblack copper-gold-zinc-silver project in southeast Alaska. Complete assay results have been received and the important intersections from 10 new holes are presented below. The additional data and information will be used in advancing the project to prefeasibility.

Two rigs were utilized to drill approximately 15,500 feet of surface core drilling in 10 holes. The helicopter-supported surface drill program, completed between July and September 2012, was designed to delineate extensions to the defined resources identified at the Trio and Lookout deposits. The first set of holes was drilled at Trio with favorable geology and mineralization encountered, so the program focused on delineation and extension of the Trio mineralized zones.

"Heatherdale's team performed with a high degree of efficiency and added significant value to the Niblack Project over the eight-week program. The drill pattern and drill hole spacing employed was designed to provide the most effective means of adding to the inferred resource at Trio. These ten drill holes were successful in extending the Trio mineralization down dip and demonstrated that the felsic host stratigraphy flattens to the south. This provides exceptional potential for extending the mineralization even further by drilling to reasonable depths from surface in 2013. In addition, drill holes S171 and S173 located the furthest down dip show evidence that the mineralized felsic package is becoming thicker with a higher frequency of significant mineralized intervals. This leads me to believe that the system is strengthening to the south and west at depth," said Patrick Smith, Heatherdale President and CEO.

"The Trio and Lookout deposits are similar, as they both are characterized by replacement style mineralization in tuff units. However, at Trio we observe two and sometimes three mineralized horizons separated by a unit called the 'white rhyolite'. The white rhyolite unit (which is absent at Lookout) also resulted in the local development of a brittle-fracture network in-filled with sulphides to produce a classic 'stringer zone' in a rhyolite flow dome sequence. The technical team is excited about this stringer style mineralization and further refinement of the geologic model to guide us to additional mineralization between the Trio and Lookout deposits as well as other occurrences within the Niblack district."

Smith added "These holes have further validated the application of Heatherdale's geological interpretation at Niblack, as well as confirming excellent potential to find new zones and increase mineral resources."

Heatherdale has announced two resource expansions since becoming involved with Niblack in 2009, the most recent in November 2011. At a US$50 net smelter return (NSR) cut off , the current resources comprise 5.6 million tonnes of indicated grading 0.95% copper, 1.75 g/t gold, 1.73% zinc, 29.52 g/t silver and an additional 3.4 million tonnes of inferred grading 0.81% copper, 1.32 g/t gold, 1.29% zinc, 20.10 g/t silver. Within the indicated resource, there is a continuous high grade zone which, at a US$150 NSR cut off, comprises 1.2 million tonnes grading 1.71% copper, 3.21 g/t gold, 3.83% zinc, 62.68 g/t silver. These mineral resource expansions are providing a strong foundation for engineering and scoping studies.

Important intersections from these 10 new holes are listed in the Niblack Assay Table below. An isometric diagram showing the location of the new mineralization at Trio has been posted to the Heatherdale website at http://www.heatherdaleresources.com/i/hdr/pdf/HTR_NR_29Nov2012.pdf.

"I am very pleased to see that many of the critical elements of a successful and sustainable mining project have come together at Niblack over the last 12 months", says Smith. The Niblack Project has excellent access and infrastructure, secure land tenure in a stable jurisdiction, a robust resource with very good mining characteristics, straightforward metallurgy, and has excellent exploration upside. We have a reliable permitting process and strong community support as exemplified by our Memorandum of Understanding with the Ketchikan Gateway Borough relating to a potential mill site located at the Gravina Island Industrial Complex and by the efforts of the communities on Prince of Wales Island and the Alaska delegation (See Heatherdale News Release dated July 16, 2012) to provide a road corridor to the Niblack property by way of a bill introduced into Congress earlier this year."

About the Niblack Project

Niblack's location at tidewater provides year-around marine access and presents a number of project cost benefits, including accessibility to Southeast Alaska's skilled 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.

Sample preparation and analysis for the Niblack project is done at ISO/IEC 17025:2005 accredited ALS Minerals 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.

Information Concerning Estimates of Indicated and Inferred Resources

This news release uses the terms "indicated resources" and "inferred resources". Heatherdale advises investors that although these terms are recognized and required by Canadian regulations (under National Instrument 43-101 Standards of Disclosure for Mineral Projects), the U.S. Securities and Exchange Commission does not recognize them. Investors are cautioned not to assume that any part or all of the mineral deposits in these categories will ever be converted into reserves. In addition, "inferred resources" have a great amount of uncertainty as to their existence, and economic and legal feasibility. It cannot be assumed that all or any part of an Inferred Mineral Resource will ever be upgraded to a higher category. Under Canadian rules, estimates of Inferred Mineral Resources may not form the basis of feasibility or pre-feasibility studies, or economic studies except for Preliminary Assessment as defined under 43-101. Investors are cautioned not to assume that part or all of an inferred resource exists, or is economically or legally mineable.
