Canada-based Northern Shield Resources has announced results from its current exploration program at the Shot Rock Property in Nova Scotia.
These results show the continued identification of gold-anomalous to gold-bearing quartz veins in outcrop and boulders, and the significant expansion of the area hosting the epithermal system.
Shot Rock is being explored for low sulphidation epithermal gold mineralization through Northern Shield’s wholly-owned subsidiary, Seabourne Resources Inc., which can earn up to an 80% interest in the Property.
Twenty-four of the 42 samples of quartz vein material recently submitted for analysis returned anomalous gold (>0.025 g/t Au).
The highest assay of 2.5 g/t Au and 17.0 g/t Ag came from a large angular boulder composed of stockwork quartz veining hosted within a rhyolitic rock that also contains disseminated pyrite. Importantly, one of the larger banded quartz veins previously found in outcrop at the Property by Northern Shield (see press release dated November 7, 2018) assayed 0.47 g/t Au.
The textures and mineralogy of the quartz veins in outcrop and boulders from the Property are believed by Northern Shield to be consistent with the upper levels of epithermal gold systems, likely above the boiling cap.
In typical epithermal systems, only modestly anomalous gold is expected to be seen above the boiling cap. If higher grades exist, they are usually found below, or at the level of the boiling cap.
In addition to the results from the above-mentioned samples, further prospecting and sampling has been undertaken. These samples are being submitted for analysis and assays are pending. This sampling has considerably expanded the footprint of the low sulphidation epithermal systems at the Highway Zone.
The core area, where large-scale quartz veins and zones of intense stockwork have been found in outcrop, has been increased from 350 metres across to approximately 550 metres.
In addition, numerous large angular boulders up to 1.5 metres in diameter consisting of crustiform/colloform banded quartz veins and stockwork veining, have been identified up-ice and up-hill from these outcrops which could further expand the cross-section vein system by 650 metres to the north. Outcrops and boulders with banded and crystalline quartz veins have also been identified 1,900 metres and 1,600 metres east and west respectively, along strike from this core area.
Northern Shield president and CEO Ian Bliss said: “We are very happy with the progress at Shot Rock. Although at an early stage, we continue to check a lot of critical technical boxes; firstly, the fluids forming these veins are gold-rich as indicated by the assays; rock textures provide evidence for a prolonged history of hydrothermal activity and efficient, vigorous boiling and; the numerous cycles of banding each represent a discrete boiling event. All these criteria are prerequisite to “grow” large and productive epithermal systems.
“Furthermore, we keep expanding the footprint of this system by finding new areas of quartz veining and mineralization. We look forward to continuing to advance our exploration of the Property over winter.”
The programs are being overseen by Christine Vaillancourt, P. Geo., the Company’s Chief Geologist and a Qualified Person under National Instrument 43-101. Samples from the program will be analyzed by ALS Global in Sudbury, Ontario and in Vancouver, BC, for Au by Fire Assay with ICP-AES finish and base metals by four acid digestion and ICP-AES. All standards and duplicates by ALS Global meet targeted values.
