Breaking Barriers Underground With 72,600 Tonnes of Rock Blasted from the Surface
Big moment underground when Austin Powder and Nyrstar successfully fired a historic surface-initiated underground blast, safely breaking 72,600+ tonnes from Immel Mine’s Stope 25 77 W, with zero personnel underground.
Using the E*STAR CUBE centralized blasting system, the team remotely verified and fired 1,350 electronic detonators from the surface, delivering millisecond-accurate timing, full digital traceability, and unmatched control for one of the largest stope blasts executed this way.
The result? Improved safety, reduced misfire risk, precise fragmentation, and a complete digital audit trail — proving that large-scale underground blasting can be safer, smarter, and fully connected. This milestone marks the next chapter in a six-year partnership built on trust, innovation, and the pursuit of what’s possible underground. Read the full Benefit Study at this link.
