The primary objective of the testing presented in this report was to further enhance and expand the Project’s understanding of the potential geochemical reactivity of the scavenger tailings, although some process waters and pyrite tailings from the 2014 pilot plant were also tested.

Wetland and floodplain analysis of a 2,422-acre area of federal land being proposed for exchange for more than 5,000 acres of RCM privately owned conservation parcels.

An evaluation of approximately 539-acre area for the presence of potential waters to the U.S.

This report presents a flood-duration flow frequency analysis for selected durations (1 day, 3 day, 7 day, 15 day, and 30 day) at 173 streamgaging stations throughout Arizona and in western New Mexico.

An evaluation of an approximately 14,273-acre area for the presence of potential waters of the U.S.

This technical memorandum was prepared to document results and analysis of a 90-day aquifer test conducted by RCM at well HRES-20 completed in the Apache Leap Tuff (ALT) aquifer.

This plan describes the procedures followed by RCM for the EPS activities to prevent, control, and mitigate releases of oil and petroleum products to the environment at its RCM EPS located near the Town of Superior, in Pinal County, Arizona.

This plan describes the procedures followed by RCM for the WPS activities to prevent, control, and mitigate releases of oil and petroleum products to the environment at its RCM WPS located near the Town of Superior, in Pinal County, Arizona.

Flooding is among the worst natural disasters responsible for loss of life and property in Arizona, underscoring the importance of accurate estimation of flood magnitude for proper structural design and floodplain mapping. Twenty-four years of additional peak-flow data have been recorded since the last comprehensive regional flood frequency analysis conducted in Arizona. Periodically, flood frequency estimates and regional regression equations must be revised to maintain the accurate estimation of flood frequency and magnitude.

The goals of the baseline surface water monitoring program are to: a) Refine understanding of surface water  occurrence, quantity, and quality within the study are b) Develop a baseline data set against which future potential impacts from mining may be measured, and c) Support development of an EIS.
