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…
