CEO.CA Chairman's Briefing

VANCOUVER, BC / ACCESSWIRE / March 16, 2021 / Heatherdale Resources Ltd. ("Heatherdale" or the "Company") (TSXV:HTR) is pleased to announce that drill and geological crews have mobilized to Heatherdale's 100%-owned Niblack copper-gold-silver-zinc VMS Project, located at tidewater in southeast Alaska. Two underground core rigs are committed to the Project that will step out along strike and down-dip from the Lookout Zone, the largest deposit that has been discovered to-date on the Property. Assays remain pending for the Q4 2020 drill program that targeted the historic Mine on the Property; results are expected from the lab in approximately one month.

"We are excited to get drilling underway from the production sized underground ramp at Niblack targeting exceptional grades of copper, gold, zinc and silver mineralization along strike to the west as well as both up and down-dip stepouts from previous intercepts." said Rob McLeod, President and CEO of Heatherdale. "The Lookout Deposit is wide open for expansion, with the current Mineral Resource open for expansion from some of the highest-grade results encountered to-date on the Property."

Initial planned underground holes at the Lookout Zone will step out up-dip and along strike from previous holes U131 which intersected 12.2 meters averaging 4.1% Cu, 10.4 g/t Au, 11.6% Zn and 239.9 g/t Ag and U132 which intersected 4.1% Cu, 8.2 g/t Au, 13.1% Zn and 194.1 g/t Ag with coarse-grained, massive sulphide mineralization, hosted in felsic volcanic rocks. Additional holes on the same section will step out down-dip from U032 which intersected 1.2 meters averaging 2.2% Cu 3.5 g/t Au, 1.3% Zn and 61 g/t Ag.

Additionally, a pattern of holes is planned to test for the down-dip extension for the Lookout Zone, around previous hole U074 which intersected 1.5 meters averaging 2.0% Cu, 3.30 g/t Au, 23.3% Zn and 90.0 g/t Ag. These planned holes will be used to vector towards wider areas of mineralization which comprise the bulk of the resource at Niblack. The intercept in drill hole U074 is located approximately 80 meters down-dip of the current Mineral Resource.

Up to fourteen drill holes are planned as part of this program, with additional drilling dependent on visual observation of mineralization, as well as other geological controls, identified in initial holes.
