Heatherdale Resources Exploration Drilling Update at the Niblack Copper-Gold-Silver-Zinc Project, Alaska

VANCOUVER, BC, Jan. 6, 2021 /PRNewswire/ - Heatherdale Resources Ltd. ("Heatherdale" or the "Company") (TSXV: HTR) announces that the Phase I surface diamond drilling program was recently completed at its 100%-owned Niblack copper-gold-silver-zinc project, located near tidewater in southeast Alaska.  Crews have returned home for the holiday break with drilling expected to recommence in February.  During the fall 2020 program, 10 holes were completed totaling 1,774 meters.  Based on encouraging visual results in the first four planned holes, all drilling during this program targeted the historic Niblack mine area, with step-out drilling at the Lookout Deposit deferred until 2021.  All assay results are pending.

"We are exceptionally encouraged with our first round of drilling, targeting some of the highest-grade massive-sulphide mineralization that has been recognized on the Property," said Robert McLeod, President and CEO of Heatherdale.  "Our drilling has confirmed that the new geological theory, developed since the last drilling program eight years ago, has recognized that a synform hosts the VMS-style mineralization at the old mine, rather than an antiform.  This confirmation has significantly increased the exploration potential of this area and the entire Niblack Property."

The 2020 drilling program at Niblack targeted both the east and west limbs of the fold as well as structurally thickening within the fold hinge, located approximately 140 meters below surface and down-plunge from the historic mine workings.  Heatherdale intends to follow-up this area with additional surface drilling to the north and south of the historic mine, with the intent of delineating sufficient extent and continuity for an initial Mineral Resource estimate at this Zone.  This drilling will be in addition to the underground exploration and resource expansion drilling at the Lookout Deposit, located over one kilometer south of the historic mine.

Significant underground rehabilitation of the 850 meter long, production-size exploration drift was completed which will enable underground drilling, ideally with two underground rigs, commencing in February, 2021.  With the Niblack Project located on tidewater and a barge camp to support operations, year-round cost-effective exploration is possible at the Niblack Property.

Historic Niblack Mine

The historic Niblack Mine is located over 1,000 meters north of current Mineral Resources at Lookout and Trio Zones.  Direct-shipping copper mineralization was discovered at Niblack Anchorage in 1899 with production from 1902 through 1908.  According to Alaska Territorial Government Records, 30,000 tons were mined averaging 3.2% Cu, 1.3 g/t Au, and 21 g/t Ag.  22 holes were completed by previous operators.  Previous drill intercepts include: LO-065 which intersected 4.6 meters averaging 5.8% Cu, 2.3 g/t Au, 3.8% Zn and 63.2 g/t Ag, as well as LO-067 which intersected 4.9 meters averaging 5.1% Cu, 13.1 g/t Au, 4.0% Zn and 149.1 g/t Ag. 

High-grade VMS-style mineralization outcrops along the shoreline adjacent to the historic workings.  A geological reinterpretation of the host-rock units, which was confirmed during the 2020 drilling program, supported by radiometric age-dating has suggested that the mineralization is hosted within an overturned antiform type fold (synform).  This structure appears to plunge to the east, suggesting mineralization is wide open for expansion along trend and plunge from the historic stopes and high-grade historic intercepts.  Sea-floor exhalative mineralization includes well-preserved volcanic textures of massive chalcopyrite, sphalerite and pyrite often associated with silica-magnetite exhalative iron-formation.

Highlights of previous drilling at the historic Niblack mine include:

Covid-19 Protocol
