“…There was also a shift in the distribution of certain REEs, showing a low depletion of cerium in areas associated with inflows from mine workings (Penn Mine, Warden Gulch) as well as acidic condition, and increasing cerium depletion appearing related to rising pH (Table S4). These concentrations at the stream and mine sites in the Snake River watershed were 2 to 3 orders of magnitude higher that the concentrations of REEs that were observed in a sample from Dillon Reservoir at a depth of 30 m near the inflow from the Snake River, which was also collected in late August …”

In the western USA, one legacy of historic mining is drainage of acidic, metal-rich water generated by exposure to oxygen of sulfide minerals in mine workings, referred to as acid mine drainage (AMD). Streams receiving AMD and natural acid rock drainage (ARD) have a low pH, high dissolved metal concentrations, and extensive streambed oxide deposits. Recently, enhanced ARD generation in the Snake River watershed in the Rocky Mountains has been shown to be associated with warmer summer air temperatures, which has been attributed to expanding weathering fronts that promote oxidation due to earlier drying of shallow soils. In mountain watersheds where complex orogeny disseminated minerals throughout the landscape, weathering processes may also mobilize rare earth elements (REEs). We report that in the Snake River REEs are currently distributed in streams at concentrations ranging from 1 to 100 μg/L. Further, analysis of archived sample indicates that REE increases over time are also associated with increased summer air temperatures. In downstream reaches where the Snake River discharges into a water supply reservoir, colloidal and particulate metal oxides are abundant and sorptive processes may influence REE speciation. We also show that REEs accumulate in benthic invertebrates at concentrations comparable to toxic metals associated with ARD.

“…Castendyk et al (2019) and Straight et al (2021) report the application of UAVs to monitoring pit wastewater from the perspective of limited accessibility to mine pits over the long term for monitoring. Hence, Castendyk et al (2019) and Straight et al (2021) discuss the cost benefits associated with UAV data collection compared to traditional environmental surveys. Castendyk et al (2019) propose that UAVs show potential to improve safety associated with sampling by eliminating the need for personnel to access the pit lake water surface.…”

This paper discusses integrating Unmanned Aerial Vehicle (UAV) data, Artificial Intelligence (AI), and Mixed Reality (MR) as a hybrid system for monitoring mine site rehabilitation. UAV systems are reviewed and the application of MR and AI to mining is discussed. The most common UAVs are low-cost multi-rotor systems however, their capabilities may be limited for long-term autonomous operation. The application scope is broad but identifies many trial UAV applications and sensors that could be integrated with MR and AI to produce an autonomous system. A simplified model for autonomous UAV, AI, and MR integrated systems is suggested along with some core modules. Via collaborative, modular development, the integration of UAV data, AI, and MR may be possible. Such a system will provide a powerful tool for mine site rehabilitation and compliance sign-off via a visual tool that allows all stakeholders to comprehend processes and data and agree when final rehabilitation is achieved.
