Northern Shield expands Creston porphyry mineralization

Executive Summary

• Northern Shield Resources Inc. reports the exposure of a large area of porphyry-style mineralization at the Creston Copper target on its 100%-owned Root & Cellar property in southeastern Newfoundland.
• The newly exposed mineralization covers approximately 50 metres by 30 metres and consists of pyrite-galena-sphalerite-bearing quartz veinlets, fractures, and breccia fillings hosted in diatreme breccia and rhyolite dikes.
• This zone is adjacent to a recently discovered hydrothermal breccia vent and 50 metres from previously identified breccia-hosted copper mineralization, supporting the interpretation of an outer zone of a Cu-Mo-Ag (Au-Te) porphyry system.

Key Details

• Location: Creston Copper target, Root & Cellar property, Burin Peninsula, southeastern Newfoundland.
• Mineralization Characteristics:
  • Exposed area: ~50m x 30m.
  • Host rock: Diatreme breccia and rhyolite dikes.
  • Mineralogy: Variable concentrations of pyrite, galena (lead sulphide), sphalerite (lead-zinc), quartz veinlets, fractures, and breccia fillings; minor chalcopyrite, chalcocite, molybdenite, and other sulphide minerals.
• Historical Context & Adjacent Mineralization:
  • The new zone is adjacent to a hydrothermal breccia vent and 50m from breccia-hosted copper mineralization (originally discovered by a prospector, per May 21, 2019 release).
  • Copper mineralization plus/minus molybdenite, gold, silver, and tellurium is exposed in four of five aggregate quarries over a strike length of 570 metres.
• Previous Assay Results (Rock Grab Samples):
  • Sample 1: 8.5% Cu, 1.1% Mo, 0.13 g/t Au, 54 g/t Ag, 60 ppm Te.
  • Sample 2: Up to 1.2% Cu.
• Current Status:
  • Assay results from the new rock grab samples are pending.
  • Induced polarization (IP) and/or magnetotelluric (MT) geophysical surveys over the expanded Creston target area are currently out for tender.
• Geological Interpretation:
  • The zone follows a magnetic trend coincident with copper-molybdenite-anomalous soil samples.
  • The position adjacent to copper mineralization is consistent with the outer zone of Cu-Mo-Ag (Au-Te) porphyry systems.

Notable Quotes

• "We are excited by the rapid changes in geology and mineralization and the zone of lead-zinc veins and breccias. This is the largest area of mineralization exposed to date at the Creston target and its position adjacent to the copper mineralization is consistent with the outer zone of Cu-Mo-Ag (Au-Te) porphyry systems and is most encouraging. We have been discovering increasingly substantial mineralization since intensifying our focus on the Creston target last summer, and we are eager to see the results of the geophysical surveys," said Ian Bliss, president and chief executive officer, Northern Shield.
