Bunker Hill Mining (OTCQB:BHLL) reported that its board approved Amended and Restated By-laws on August 1, 2026, effective immediately and superseding the prior by-laws.

Bunker Hill Mining (OTCQB:BHLL, TSX:BNKR) has shipped its first lead-zinc concentrate from the Bunker Hill Mine to Teck Resources’ Trail Smelter, marking its first revenue-generating concentrate sales in more than 45 years and a key milestone in the mine’s restart.
The newly commissioned processing plant in Kellogg, Idaho is designed for 1,800 tpd, with expansion potential to about 2,500 tpd, and uses modern differential flotation and dry-stack tailings. The locally recruited team is finalizing commissioning toward 24/7 operations, with full commercial production targeted by the end of 2026. Concentrate is assayed by Silver Valley Analytical and hauled roughly 140 miles to Trail under existing offtake arrangements.
Bunker Hill also drew US$5 million under its standby facility with Teck and affiliates to support working capital and ramp-up activities, providing additional liquidity and financial flexibility during the early years of operations.
