Engineering, Evaluations, Permitting, and Remediation

VESTRA offers a full range of engineering, hydrology, geotechnical, and environmental science services
to the mining industry. This includes working with abandoned underground mining operations, active quarries, and on-stream gravel operations.

Our engineering, environmental sciences, and geotechnical staff bring decades of experience to each
project. Projects have ranged from permitting, design, and SMARA inspections to closure and remediation
activities. We also have conducted numerous special studies, including biological assessments and
comprehensive mercury characterization studies.

We act as client advocates and with years of working with the mining industry have developed and
maintained close professional relationships with regulatory agencies and those individuals responsible
for reviews and permit approval.
