March 19, 2010, Vancouver, BC -- Heatherdale Resources Ltd. ("Heatherdale" or the "the Company") (TSXV: HTR) announces that intersections of high-grade copper-gold-silver-zinc mineralization continue to be encountered in underground drilling at the Niblack Project in southeast Alaska. The ongoing drill program is utilizing two rigs which are presently focused on delineating the new, precious-metals enriched massive sulphide discovery located southwest of the Lookout Deposit; one of six known volcanogenic massive sulphide ("VMS") deposits within the 10 square mile Niblack property.

The two discovery holes (U027 and 28) drilled by joint venture partner CBR Gold Corp. along with the first six delineation holes (U029, 30, 31, 32, 33A and 34) were tabulated and presented in Heatherdale's January 18th news release. New intersections from the next four holes (U035, 36, 37A and 38) are presented in the Niblack Assay Table below. A Plan Map and Cross Sections showing the location of all the drill holes are available at www.heatherdaleresources.com.

Holes are being drilled in fan patterns from underground drill stations and are designed to cross-cut the high grade mineralization. To date, the true widths of the intersections have not yet been accurately established.

Heatherdale has now initiated a second and third series of underground fan drill holes at drill stations number two and three located along strike at 100 foot intervals.

"Intersections from fan drilling the first, second and third underground drill stations each located 100 feet apart have certainly demonstrated a continuity of high-grade, precious-metals enriched VMS mineralization southwest of the Lookout Deposit," said David Copeland, President and CEO of Heatherdale. "What is perhaps more exciting is that we haven't yet determined the outer dimensions of this thick high-grade copper-gold-silver-zinc mineralized body. It is still wide open."

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.

Heatherdale Resources Ltd. is a Vancouver-based exploration and development company focused on advancing the high-grade mine development opportunity at the Niblack Project. The Company will earn up to a 70% interest from CBR Gold Corp. by expending US$25 million and completing a Feasibility Study on the Niblack Project. Heatherdale is affiliated with the Hunter Dickinson group, a private company associated with successful mineral exploration and development projects around the world.

Sample preparation and analysis 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 Inductively Coupled Plasma -- Atomic Emission spectroscopy (ICP-AES) 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 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.
