J4 completes drone magnetics survey at Arthur Lake

Mr. Jeremy Poirier reports J4 VENTURES RESOURCES CORP. (FORMERLY J4 VENTURES INC.) COMPLETES DRONE MAGNETICS SURVEY AT ARTHUR LAKE J4 Ventures Resources Corp. has completed a drone magnetics survey at its 543-hectare (ha) Arthur Lake property, 54 kilometres (km) southwest of Vanderhoof, B.C. The company completed a 127-line-kilometre (km) drone magnetics survey over the property at a 50-metre (m) line spacing to better understand the geology and potential structures below the glacial cover, as well as the Little Bear-Big Bear corridor. Pioneer Exploration Consultants Ltd. completed the survey. "The magnetics survey has shown the granitic intrusion to be a strong exploration target," commented Jeremy Poirier, chief executive officer. "We plan to reinterpret the historic exploration, including a 2021 induced polarization survey in light of the new magnetic data." The magnetics appear to highlight the original granitic plug, which recent mapping and the magnetics indicate is actually more of a dike. The magnetics suggest a possible bend in trend from northwest to west-northwest, where the Little Bear and Big Bear showings and copper mineralization lie. Arthur Lake property highlights: Historical rock grab sampling returned results ranging from eight to 24,800 parts per million (ppm) copper (Cu), with 10 samples assaying in excess of 2,200 ppm Cu, largely at the Little Bear showing. Subsequent soil sampling identified three copper or copper/multielement soil anomalies; 2025 J4 rock and soil sampling and pack sack drilling at Little Bear returned grab samples of 7.2 per cent copper and 11.2 ppm silver with pack sack drill result of 0.43 per cent copper and 11.8 ppm silver; Grab sampling at the related Big Bear showing 350 m to the west-northwest returned highlights of 0.68 per cent copper and pack sack drill results of 0.23 per cent copper over 1.6 m.
