Heatherdale Resources Ltd. is a mineral exploration and development company based in Vancouver, Canada. It is publicly traded on the TSX Venture Exchange (TSX-V) under the symbol HTR. Heatherdale holds 51%, and has the right to earn a 70% interest in Niblack Project LLC. The Niblack Project comprises 6,200 acres of federal and state mineral claims, 250 acres of patented lands, and related mineral exploration permits, equipment and infrastructure on Prince of Wales Island in southeast Alaska. Six high-grade volcanogenic massive sulphide (VMS) deposits are known to occur within the Niblack mineral claims. Drilling over 15 months to December 2010 has increased mineral resources by 54%. Heatherdale expanded its development pipeline in February 2011 by acquiring a 60% interest, with the option to acquire 100%, in the Delta copper-lead-zinc-gold-silver project, located in east-central Alaska. Delta is a mid-stage exploration project. The 39,840-acre property covers a largely under-explored VMS district with strong potential for expansion of known resources and the discovery of new deposits.
