Executive Summary

  • Northern Shield Resources Inc. reported significant grab rock sample values from the Creston copper target on its Root & Cellar property in Newfoundland, indicating a polymetallic porphyry system.
  • Samples returned up to 3.9% Pb, 4.0% Zn, and 2.0% Cu, with anomalous silver and tellurium, representing the highest lead/zinc values on the property to date.
  • The company has contracted Abitibi Geophysics Ltd. for a 3-D-IP geophysical survey over the Creston target, expected to commence in late April, to aid in imaging the target zone for future drilling.

Key Details

  • Sample Results (Creston Target):
    • Grab rock samples from the diatreme breccia complex (approx. 50m x 30m area) returned up to 3.9% Pb and 4.0% Zn.
    • A grab rock sample from a quarry 375m to the north returned 2.0% Cu.
    • All samples showed anomalous silver and tellurium.
  • Geological Interpretation:
    • The Pb-Zn mineralization supports the existence of an underlying polymetallic porphyry copper system.
    • The signature of lead-zinc mineralization and molybdenum-rich hydrothermal breccia indicates late-stage, metal-rich fluids venting to the surface.
    • Metal zonation is consistent with a typical porphyry copper system: Cu/Mo in the high-temperature core, and Pb/Zn/Ag in cooler, outer/upper zones.
    • This suggests a high-grade copper core lies at depth beneath the surface features.
  • Previous Context:
    • Soils and rock grab samples anomalous in Pb-Zn-Sb-As have been noted on the periphery of the 2 km diameter Creston copper target.
  • Upcoming Activities:
    • Abitibi Geophysics Ltd. contracted for a 3-D-IP geophysical survey over the Creston target.
    • Survey expected to commence in late April.
  • Technical Details:
    • Samples analyzed by ALS Global in Vancouver, B.C.
    • Au analyzed by fire assay with ICP-AES finish (Au-ICP22).
    • Multielements analyzed by four-acid digestion and ICP-MS finish (ME-MS61).
    • All standards and duplicates met targeted values.
    • Technical information reviewed and approved by Christine Vaillancourt, PGeo, Chief Geologist.
  • Disclaimer: Grab samples are inherently selective and may not be representative of overall grade, continuity, or extent of mineralization; results should not be considered indicative of underlying mineral resources.

Notable Quotes

  • "The lead-zinc mineralization, which adds to the metal endowment of the system, represents an important piece of the exploration puzzle at Creston. In porphyry copper systems, base metal zonation is predictable: copper and molybdenum concentrate in the high-temperature core, while lead, zinc and silver precipitate in the cooler, outer and upper zones as hydrothermal fluids ascend and expand. This metal zonation, combined with our Mo-rich breccia and copper showings, confirm a large-scale, vertically extensive, hydrothermal system at Creston. This suggests the high-grade copper core lies at some depth beneath the features we're seeing at surface. The upcoming 3-D-IP survey will be instrumental in imaging the target zone for drilling," commented Ian Bliss, president and chief executive officer, Northern Shield.
