“So far in 2026, Prospect Ridge has substantially advanced its portfolio of copper-gold porphyry projects, including drilling at the Excalibur greenfields target. The fact that EXC26-001 encountered significant intervals of alteration and sulphide mineralization consistent with porphyry-style systems* suggests that Excalibur could host a new discovery in the Babine porphyry belt.” - Len Brownlie, Ph.D., President and CEO * The Company emphasizes that visual descriptions of drill core intercepts or mineralized structures are only qualitative and not quantitative. 👉 prospectridgeresources.com/f… $PRR.CN $PRRSF #Mining #Copper #NewsRelease

Copper Prices Strengthen Amid Supply Concerns 📈 🟠 Copper was heading toward a 2% weekly gain as mine disruptions, resilient Chinese demand, and tightening inventories outside the U.S. supported prices. 📋 Key market developments: • China’s Yangshan #copper premium hit a four-year high of US$135 per tonne; • LME warehouse inventories fell to a six-week low; • A potential strike at Chile’s Centinela mine could affect output as early as November; • Record U.S. stockpiles remain a source of market uncertainty. Supply disruptions are providing support, but demand trends and U.S. inventory levels remain important factors to watch. 👉 kitco.com/news/off-the-wire/… #Mining #CriticalMetals

Copper Is in Uncharted Territory 🟠 #Copper positioning has reached its most extreme level in available COT data going back to 1995. Normally, that’s a bearish warning—but Kitco contributor Thomas Lukacs points to an intriguing precedent. 📈 In 2003, copper hit what was then an all-time COT extreme and kept climbing, as pressure on commercial short positions potentially added fuel to the rally. Will history rhyme—or is copper due for a reversal? 👉 kitco.com/opinion/2026-08-31… #Mining #CriticalMetals
