Porvenir is a 100%-owned, stand-alone underground polymetallic development project within the Hemco Property. The March 2026 PFS is based on mechanized sub-level stoping and bench-and-fill extraction feeding a 2,000 tpd dedicated plant with flotation, cyanidation and Merrill-Crowe recovery to produce copper-lead concentrate containing gold and silver, zinc concentrate and gold-silver doré. Subsequent permitting disclosure describes approved infrastructure at 2,500 tpd, creating scope for a larger permitted configuration than the PFS base case. Nearby Leticia, Guillermina, San Antonio and Apoyo mineralization may provide future satellite feed but is excluded from Porvenir's deposit-level estimates reported here.
