Advanced Blasting – Stebbins Quarry -2015

Advanced Blasting and the City of Stebbins requested that AES visit their quarry, take samples from both the surface and from blast hole drilling, estimate the size of resource and make recommendations.  The primary rock underlying the Stebbins and the quarry site is layered basalt flows. The quarry itself lies within the bounds of a small Holocene volcanic ash cone. The core of the cone contains the remnants of a flow center with an irregular neck of dense, low gas-bubble basalts.
