We are sad to announce that Otto Schumacher, Edumine online course author and short course presenter, passed away on September 27, 2018 at age 76 in Spokane, WA, USA.
Otto worked as a mining engineer and geologist in underground mine operations for base and precious metals, and exploration projects for uranium and iron. He specialized in mining cost and economic analysis when he joined the U.S. Bureau of Mines as Supervisor, Mining Feasibility Analysis Group, where he was responsible for development of aspects of Bureau systems for mine cost estimating and mineral property evaluation.
In 1983, he started Western Mine Engineering, Inc., the predecessor to InfoMine’s CostMine division, where he consulted, taught seminars about mine evaluations, and developed the Mining Cost Service and related publications.

With deepest sympathies,
The Edumine Team
