J4 completes drone magnetics survey at Arthur Lake

• J4 Ventures Resources Corp. completed a 127-line-kilometre drone magnetics survey at its Arthur Lake property in British Columbia on April 20, 2026.
• Survey results suggest a granitic intrusion is actually a dike and indicate a potential trend bend from northwest to west-northwest near the Little Bear and Big Bear showings.
• The company plans to reinterpret historic exploration data, including a 2021 induced polarization (IP) survey, using the new magnetic data.
• Recent 2025 sampling at the Little Bear showing yielded high-grade copper grab samples of up to 7.2% Cu and pack-sack drill results of 0.43% Cu over 1.8m.
• Big Bear Showing (350 m WNW of Little Bear) returned grab samples of 0.68% Cu and pack-sack drill results of 0.23% Cu over 1.6m.

• The news is a direct follow-up to the March 11, 2026 announcement that the survey had begun; completion was expected by April.
• No new drill intercepts were announced in this release, only geophysical interpretation and references to historic grab samples which are selective and not bulk tonnage data.
• The market reaction has been muted relative to the January acquisition spike, with price consolidating between $0.14 and $0.25 since February.
• This is a Routine - Positive update as it confirms operational progress but does not materially alter the valuation without confirmed drilling results.

• J4 Ventures Resources Corp. (Ticker: JJJJ) is a TSX-V Tier 2 mining issuer focused on copper-gold exploration in British Columbia.
• Flagship Project: Arthur Lake Property, consisting of two claim units totaling 543 hectares located ~54 km SW of Vanderhoof, BC.
• Mineralization: Prospective for gold-plus porphyry copper-molybdenum mineralization. Historic grab samples returned up to 24,800 ppm Cu (2.48%).
• Recent Exploration: Little Bear and Big Bear showings have yielded high-grade surface samples but lack bulk drilling confirmation in the provided news cycle.
