Class 1 samples 1.11 g/t Pd+Pt+Au at River Valley

Executive Summary

• Class 1 Nickel reports a successful 2025 surface‑sampling campaign on the River Valley PGE‑Cu‑Ni project, highlighting a 3‑metre intercept with 1.11 g/t Pd+Pt+Au (3E) and up to 0.96 % Cu in grab samples.
• The program generated several new targets for follow‑up ground geophysics and a planned drilling campaign on the North PGE and Crerar trends.
• Historical drill results from Mustang Minerals (2001) are reiterated, showing multiple sub‑meter to multi‑metre zones with 0.30–2.26 g/t 3E, underscoring the project's prospective nature.

Key Details

• Project Overview: River Valley PGE‑Cu‑Ni project (~2,916 ha) located ~65 km NE of Sudbury, Ontario; hosts contact‑style PGE‑Cu‑Ni sulphide mineralization within the River Valley intrusion.
• Sampling Program: 73 rock grab samples collected from outcrop and assayed for multi‑element chemistry (samples are selective, intended to prove presence of mineralization).
• Top Assay Highlights (grab samples):
• 0.96 % Cu, 0.17 % Ni, 0.47 g/t 3E, 3.28 g/t Ag
• 0.54 % Cu, 0.19 g/t 3E, 0.54 g/t Ag
• 1.11 g/t 3E, 0.77 g/t Ag
• Highest‑grade Grab Samples (11 inclusion‑bearing/melagabbro samples):
• Cu: 0.04–0.96 %
• Ni: 0.02–0.17 %
• 3E (Pd+Pt+Au): 0.26–1.11 g/t
• Planned Follow‑up: Surface geophysics program slated for the North PGE trend and Crerar PGE trend to refine targets ahead of a near‑term drilling campaign.
• Historical Drill Data (Mustang Minerals, 2001):
• Hole MRS‑01‑1: 0.30 g/t 3E over 6.80 m; 0.31 g/t 3E over 5.45 m
• Hole MRS‑01‑6: 0.58 g/t 3E over 7.00 m
• Hole MRS‑01‑7: 0.61 g/t 3E over 3.00 m
• Hole MRS‑01‑2: 2.26 g/t 3E over 1.50 m; 0.82 g/t 3E over 7.00 m
• Hole MRS‑01‑9: 0.58 g/t 3E over 3.00 m
• Hole MRS‑01‑10: 0.51 g/t 3E over 9.00 m
• Qualified Person: Dr. Scott Jobin‑Bevans (PGeo, PGO No. 0183) reviewed and approved technical information per NI 43‑101.

Notable Quotes

“Results from this surface sampling program, combined with results from the VTEM airborne geophysical survey completed earlier this year… give us confidence to continue with additional exploration in the target areas… plan and complete a drilling program in the near future.” – David Fitch, CEO, Class 1 Nickel.
