EnviroMINE is a San Diego-based mine consulting firm with over 30 years of experience operating throughout the Western United States, with a second office located in Napa, CA.

The firm offers a full range of environmental consulting and project management services for both the public and private sectors.  EnviroMINE leverages its hands-on mining experience while advocating for its clients throughout the entitlement process.

EnviroMINE, Inc. was established in 1992 by Warren R. Coalson, an expert in mining operations.  His extensive experience includes mine planning and development, regulatory compliance and environmental analysis.  As an expert in mining and reclamation, Coalson was called upon to develop the financial assurance estimating guidelines adopted by the State Mining and Geology Board. 

Coalson and his staff have served as project manager in the preparation of hundreds of technical and environmental documents for a wide range of mineral resource development projects.   His knowledge of mining and land use planning principles, coupled with a winning attitude, continues to have a positive impact on the EnviroMINE staff, and ultimately every project in which the company is involved.
