The proposed Mt. Hope project — a primary development interest of General Moly — targets a 1.3 billion pound molybdenum reserve. Because the project is located on BLM land, an EIS is required to predict the regional effects of the proposed mining operations.
Environmental Impact Studies
- Characterized the fractured-rock hydrogeology of the planned pit area
- Designed and implemented a well drilling / testing program to obtain the data needed to characterize hydrologic conditions in the fractured-rock aquifer
- Led hydraulic testing activities near the proposed mine facilities and open pit
- Designed and implemented a groundwater monitoring program for the proposed mine area
- Established a data collection and transfer system to facilitate rapid analysis by the EIS team
- Prepared a comprehensive report that met the rigorous requirements of EIS approval process
- Provided technical support services during the regulatory review process
M&A developed a 3D groundwater flow model for the fractured rock aquifer and used it to…
- Identify pit-dewatering requirements
- Predict groundwater level changes during and after mining operations
- Create a water balance for the post-closure pit lake
- Assess whether the future pit lake would remain a passive hydraulic sink
- Develop sector-specific pit-radius inflows, characterized by rock type, to support a geochemical pit-lake analysis by a partner consultant
We coupled this local model with a regional model (developed by a partner consultant) to project the impact of the proposed mining operations on groundwater conditions in Diamond Valley.
