intercept returned 14,394.5 grams per tonne over 0.75 metres. Approximately 17,500 metres of drilling at Skeena Resources Limited's Spectrum project was designed to define a near-surface, high-grade gold resource. Skeena also acquired the GJ copper-gold prospect from Teck Resources Limited and NGEx Resources Inc. PORPHYRY (COPPER-GOLD, COPPER- MOLYBDENUM AND MOLYBDENUM) PROJECTS The first copper-gold-bearing concentrate from Imperial Metals Corporation's Red Chris mine was shipped to Asia in April. Mining progressed at the Main-zone and East-zone pits, and included zones of higher copper and gold grades than anticipated. Commercial production was achieved on July 1, as mill throughput surpassed 30,000 tonnes per day. Optimization of milling and processing procedures is ongoing. Production continued at the Huckleberry copper-gold-silver-molybdenum mine, co- owned by Imperial Metals Corporation and Japan Group (Mitsubishi Materials Corporation; Dowa Mining Co., Ltd.; and Furukawa Co., Ltd.), as the main-zone opti- mization plan progressed through year four. Exploration drilling at Whiting Creek tested near-mine targets. Seabridge Gold Inc. expanded the copper-gold Kerr- Sulphurets-Mitchell (KSM) project, with deep drilling at the Deep Kerr zone and the Mitchell zone. Results included 196.8 metres grading 0.69 grams per tonne gold and 0.72 per cent copper from a 1,358.2-metre depth, indicating continuation of Quartz-magnetite-bornite veins at Imperial Metals Corporation's Red Chris mine.
