Feature Story in Aggregates Manager about how Kespry Drones are improving stockpile analysis and safety.

The Greens Creek mine, owned and operated by Hecla Mining Co, produces gold, silver, lead and zinc from an underground mining operation on Admiralty Island, Alaska. Employees must travel a 19-kilometer, single-lane access road to access the mine site, which is shared with ore haulage and freight trucks. Hecla sought a simple and robust way to augment its radio call-out procedures to increase driver awareness of approaching traffic and improve safety on the access road.
