📢 NEWS: Sun Summit Receives Positive Metallurgical Test Results for the JD Project Sun Summit is pleased to report positive metallurgical test results demonstrating recoveries of up to 99% from the JD Project, Toodoggone Mining District, north-central British Columbia. CEO Niel Marotta commented: "Initial metallurgical test results from both the Creek and Finn Zone composites demonstrate high recoveries and grades, highlighted by exceptional gold performance. The conventional Gravity-Leach flowsheet achieved outstanding gold recoveries ranging from 89% to 98%, while an optimized Gravity-Float-Leach procedure demonstrated total gold extraction of 100%. Importantly, these results show a large percentage of gravity recoverable gold." 🔗 sunsummitminerals.com/sun-su… $SMN.V $SMREF #Gold #Silver #JDProject #Toodoggone #Metallurgy #MRE

📢 NEWS | Sun Summit has completed its 2026 exploration program at the Theory Copper-Gold Project in BC's Toodoggone District. The three-phase program included prospecting, geological mapping, geochemical sampling, and IP geophysics in select target areas. "Our successful three-phase exploration program at Theory, running alongside an aggressive 16,000-meter drill campaign at our flagship JD project, caps off an exceptional season of operational execution. Discovering widespread copper mineralization at the surface of newly discovered zones—backed by fresh ground IP and airborne MobileMT data—gives us a powerful toolkit to refine our targets and map out a historic, first-ever drilling campaign for 2027. We continue to unlock significant value at the highly under-explored Theory Project and look forward to updating the market as rock and soil results are received and interpreted." — Niel Marotta, CEO, Sun Summit Minerals Assay results pending. All results aimed at prioritizing targets for a planned 2027 drill campaign. 🔗sunsummitminerals.com/sun-su… $SMN.V $SMREF #Copper #Gold #TheoryProject #Toodoggone #Mining #Exploration
