Bunker Hill on Track for June Restart. Provides Corporate Update and Commissioning Progress

The most recent news release dated April 15, 2026, confirms Bunker Hill Mining Corp. remains on track for a June 2026 restart of its Idaho mine. Commissioning is focused on the mill and filter plant with active systems testing. The company initiated a new underground diamond drilling program totaling approximately 25,000 feet targeting galena mineralization and high-grade silver. A significant strategic update notes membership in the U.S. Cornerstone Consortium and the U.S. Defense Industrial Base Consortium to access funding pathways for critical minerals. Capital structure updates indicate 263,096 warrants expired on March 27, 2026, with prior exercises generating C$6.3M. The company successfully completed its uplisting to the Toronto Stock Exchange (TSX).

The operational update confirming the June restart timeline is consistent with previous announcements from March 16 and March 23, 2026, which already stated construction was 87% complete and on schedule. Therefore, the core production catalyst is not new information but a confirmation of existing expectations. The initiation of the 25,000-foot drilling program follows the previously announced exploration resumption in April 2026. However, the announcement regarding membership in the U.S. Cornerstone Consortium and Defense Industrial Base Consortium represents genuinely new strategic validation for a domestic critical mineral producer. This positions the company within U.S. government supply chain security initiatives, potentially unlocking future funding or policy support not previously priced into the equity. While operationally routine, this strategic alignment adds a layer of long-term valuation security regarding metal demand and regulatory risk. The warrant expiry and TSX uplisting are administrative milestones that reduce liquidity friction but do not materially alter cash flow projections immediately.

Bunker Hill Mining Corp. is focused on restarting the historic Bunker Hill Mine in Idaho's Coeur d'Alene Mining District. The project is a zinc-silver-lead underground mine utilizing longhole stoping with paste backfill. Construction was reported at 87% complete as of March 2026, targeting first concentrate production in June 2026. The company aims to expand throughput to 2,500 tpd (Bunker 2.0) supported by potential US EXIM financing. The project is located on a 2,300-hectare land package with significant exploration upside.
