[{"type":"text","content":" Rimouski, Quebec--(Newsfile Corp. - April 22, 2026) - Puma Exploration Inc. (TSXV: PUMA) (\"Puma\") announces that its subsidiary, Murray Brook Minerals Inc. (\"MBM\" or the \"Company\"), has received an updated NI 43-101 Technical Report for its 100%-owned Legacy Project (Cu-Ag) in Northern New Brunswick, Canada. The technical report, effective November 28, 2025, with a report date of February 20, 2026, was compiled to satisfy the listing requirements for a Tier 2 application to the TSX Venture Exchange. The updated resource estimate, based solely on historical drilling results, outlines a 930,000 tonnes inferred resource at the Legacy Deposit, containing 13,400,000 lbs Cu @ 0.66% Cu and 110,000 oz Ag @ 3.65 g/t Ag. The deposit starts at surface and shows significant expansion potential (Independent Technical Report for the Legacy Project, Restigouche County, New Brunswick, Canada, by Dr. Gilles Arseneau, P.Geo, effective November 28, 2025) (Figure 1).

Historically, drill holes were selectively sampled at intervals of less than 2 metres, targeting only visible sulphide mineralization. They were primarily assayed for copper and silver. The MBM drill holes also included some assays for gold and zinc. For the 2025 resource estimation, SRK capped assays at 10% Cu and 400 g/t Ag before compositing to 2-metre lengths. Composites with ...
