Geology

LA provides a wide array of geologic services for mineral resource evaluations, due diligence, geomorphic support for engineering studies, water quality and geochemistry studies, and geologic hazard assessments. LA has completed geologic investigations throughout the United States, Canada, Mexico, Indonesia and Papua New Guinea. Our mineral resource evaluations have addressed commodities such as gold, uranium, coal, copper, lead, zinc, sand, gravel and rock. LA has completed environmental fatal flaw analyses, reserve evaluations, permitting, mine engineering and planning.

We have developed professional, trusted relationships with several publically traded companies as part of their acquisition team. Our responsibilities include third party evaluations of mineral reserve as well as the evaluation of the environmental assets and liabilities. This work has taken us to over 14 states. LA has also served as an ISO 14000 advisor to an international based state-owned coal company assisting them in addressing environmental liabilities.

Our engineering studies often incorporate the firm’s fluvial geomorphic expertise. LA completes river stability studies- recognizing that the evaluation of historic behavior is the key to future prediction. Geomorphology, combined with strong engineering practices, allows us to provide clients with “natural solutions” that are not only cost effective but require little O&M. LA has completed geologic hazard assessments (rock fall, erosion and sedimentation, unstable foundation soils, landslides) for proposed mountain developments, slope instability investigations and remediation designs for mining and reclamation clients in Colorado, California, Wyoming and Oregon.

LA has demonstrated experience in water quality data collection, geochemistry, monitoring, and water quality modeling. Our experience includes reservoir modeling and evaluation of trophic status, assessment of nonpoint and point source pollutants, mineral hot spring equilibria, acid mine drainage, acid generation and metal dissolution from unsuitable backfill below the water table, and phosphate and salt loading to both surface and ground water systems.
