This NI 43-101 Technical Report details the operational status and life-of-mine plan for the Greens Creek Polymetallic Mine in Alaska, operated by Hecla Mining. The mine has been operational for 30 years, with continuous operation for the last 23 years. It is an underground mine targeting massive sulfide mineralization in a temperate rainforest environment. The current mine life extends to 2030, with infrastructure primarily located at the 920/860 mine area and the Hawk Inlet camp.

This report outlines the conceptual flowsheet for the Romero Project Preliminary Economic Assessment (PEA). The process is designed to treat 1,400,000 tonnes per year of ore, with a daily throughput of 4,000 tonnes. The metallurgical strategy focuses on recovering copper into a concentrate containing approximately 20% copper, along with gold and silver credits.

The Sheep Mountain Project is a uranium recovery facility utilizing conventional heap leaching technology, a process established globally for oxidized ores. The operation involves stacking mined material on a double-lined heap leach pad, applying an acidic leaching solution containing sulfuric acid and an oxidant, and collecting the pregnant leach solution (PLS) for processing. Over a 12-year mine life, the project is designed to recover an average of 1.4 million pounds of U3O8 annually.

This NI 43-101 Technical Report outlines the Feasibility Study for the Volta Grande Project, conducted by Belo Sun Mining Corp. in May 2015. The study details a processing plant design based on metallurgical test work and industry best practices, targeting gold recovery from non-refractory ores containing free grains within quartz and diorites. The process route involves gravity concentration followed by cyanidation of gravity tailings, utilizing a hybrid carbon-in-leach/carbon-in-pulp (CIL/CIP) configuration to balance capital costs and adsorption efficiency.

This NI 43-101 Technical Report presents the Pre-feasibility Study for the Kamistiatusset (Kami) Iron Ore Property in Labrador. Champion Iron Limited has reviewed the scope of the project to design a process allowing the production of a low silica grade concentrate suitable for Direct Reduction usage. The flowsheet is based on metallurgical testwork and engineering experience, incorporating major changes from the 2018 Feasibility Study to improve iron recovery and concentrate grade.

The Bethania Silver Project, formerly known as Mina Santa Elena, is a polymetallic deposit located in central Peru. Historical toll processing between 2013 and 2016 confirmed the high value silver-rich content of the mineral source, with silver reporting primarily to Pb-concentrates and remaining silver to Zn-concentrates. The principal minerals are galena and sphalerite, with silver potentially associated with sulfosalts like proustite and pyrargyrite. While past production records indicate saleable Pb and Zn concentrate grades, no metallurgical testwork has been completed to confirm the production of saleable Cu concentrates.
