PTX Metals talks W2 project mineralogy study

Executive Summary

  • PT Metals released positive preliminary mineral liberation and mineralogy results for the W2 Cu‑Ni‑PGE‑Au project, confirming favorable host minerals and high degrees of liberation.
  • The company launched a comprehensive Q3 2025 work program that includes metallurgical testing (SGS Canada), a 3‑D inversion geophysics study of recent Heli‑GT magnetic data, U‑Pb CA‑ID‑TIMS age‑dating by Dr. Steven Denyszyn, and a mineralization paragenesis study.
  • These studies are intended to refine the geological model, improve economic viability assessments, and guide an upcoming directed drill program.

Key Details

  • Mineral Liberation Results: Average liberation percentages – Pyrrhotite 96.8 %, Pyrite 94.2 %, Chalcopyrite 94.25 %, Pentlandite 92 %; copper occurs almost entirely in floatable chalcopyrite, nickel primarily in pentlandite (high‑grade) and pyrrhotite (lower‑grade).
  • Cobalt Substitution: Cobalt consistently substitutes for nickel within pentlandite across all examined samples.
  • Sample Coverage: Analyses performed on intercepts from holes W224‑03 to W224‑06 of the 2024 drill program at the Central target; company notes limited representativeness and plans further studies with newer core material.
  • Metallurgical Testing (Q3 2025): Engagement of SGS Canada Inc. in Lakefield, ON to test composites from CA and AP zones for flotation response and recovery of Cu‑Ni‑Pd‑Pt‑Au‑Co; also evaluating gravity and magnetic separation impacts.
  • Geophysics Study: Agreement with an independent geophysicist to produce a 3‑D inversion model of Heli‑GT magnetic survey data, targeting the gabbroic lithology linked to mineralization; initial interpretation suggests continuous Cu‑Ni‑Au‑PGE‑bearing gabbro horizons extending ~8 km.
  • Age‑Dating Program: Dr. Steven Denyszyn (Memorial University) contracted for U‑Pb CA‑ID‑TIMS dating of the W2 intrusion to correlate with other Ring of Fire deposits and refine metallogenic models.
  • Future Plans: Results from metallurgical tests, geophysical modeling, age‑dating, and paragenesis studies will inform a forthcoming directed drill program aimed at expanding known mineralized zones.
