Hecla Mining — May 5, 2026 release

Midas is a potential hub-and-spoke operating model, where ore sources could come from multiple regional sources and fed into the 1,200 tpd mill. There is also a permitted tailings facility on site which, with some improvements, has storage capacity of approximately 15 years at nameplate capacity of the mill.   The Company has allocated $16 million of the 2026 exploration budget for the Nevada project portfolio, more than three times the investment made in 2025. The 2026 drill program at Midas is focused on following up on the success of the 2025 drill program with a heavy focus on the Sinter Offset Zone and the Pogo target. The nearby Hollister high-grade gold and silver project is within trucking distance of the Midas mill and drilling is currently scheduled to begin on this regional project late in the second quarter. The Company aims to provide regular exploration updates for the Nevada exploration projects throughout 2026.   EXPLORATION AND PRE-DEVELOPMENT _____________________________________________________________________________________________________________   Investment and Strategy During Q1 2026, the Company invested $4.6 million in exploration and corporate development (including $0.3 million in pre-development) activities, focused on high-impact discovery drilling at Midas in Nevada and Keno Hill in Yukon, and resource expansion programs at producing assets. Exploration activity is planned to ramp up in the second and third quarters with core drills expected to increase from the 13 currently deployed to 19.
