Niblack Mineral Development and Heatherdale Achieve Major Milestone

EDMONTON, ALBERTA -- (Marketwire - June 8, 2010) - Niblack Mineral Development Inc. (TSX VENTURE: NIB) ("Niblack") and joint venture partner Heatherdale Resources Ltd. (TSX VENTURE: HTR) ("Heatherdale") announce that Heatherdale has met its initial US$5 million project investment commitment before the first anniversary date of the agreement with Niblack., and will continue to fund exploration activities to rapidly advance the precious metals-enriched Niblack volcanogenic massive sulphide (VMS) project in southeast Alaska.

Niblack Mineral Development Inc is very pleased with the progress and results of the drilling completed over the past eight months. The joint venture\'s development and confirmatory work on a geological model for the Lookout Zone is revealing strength, continuity and a spatial extent of mineralization that the technical team believes represents a district-scale opportunity, when combined with a growing understanding of the overall system. Heatherdale has indicated that it fully intends to continue necessary project investments in the months ahead to secure their 51% position and move this exciting project forward efficiently and expeditiously.

Currently two underground diamond drill rigs are working to delineate the copper-gold-silver-zinc mineral body at the Lookout Zone, one of six known VMS deposits within the 10 square mile Niblack project. The systematic, step-out drilling program continues to expand the dimensions of the newly discovered precious metals-enhanced deposit and demonstrate the strength and continuity of the mineralization.

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 km) from Ketchikan, a community of 8000 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 mine, a 2,100-ton per day underground massive sulphide operation, operates 225 miles (370 km) to the northwest of Niblack on Admiralty Island.
