This catalog has been prepared to summarize available information for selected springs and seeps in the Upper Queen Creek and Devils Canyon watersheds (UQC/DC). The springs and seeps included in this catalog were selected based on proximity to planned facilities as proposed by Resolution Copper (RC) for the Resolution mine project. The catalog was prepared by Montgomery & Associates (M&A) and WestLand Resources, Inc. (WRI) on behalf of RC.

This report was prepared for Resolution Copper (RC) to describe surface water features monitored in the Oak Flat area. Sites monitored, methods of data collection, and findings of data collection from March through September 2017 are presented. Fourteen sites were studied to provide baseline technical hydrologic monitoring in the Oak Flat area within or adjacent to the projected disturbance zone of the proposed RC block cave mine.

This report has been prepared to summarize the review and analysis of long-term hydrographs to support ongoing National Environmental Policy Act (NEPA) review process for the Resolution Project near Superior, Arizona. The principal objective of this report is to present and review groundwater level and hydraulic head data for the RC hydrologic monitoring network. Limited interpretation is provided to help describe notable hydraulic changes.

This surface water baseline report has been prepared to support the ongoing National Environmental Policy Act (NEPA) review process for the Resolution Project near Superior, Arizona. This report is an addendum to the Surface Water Baseline Report prepared by M&A (2013) that includes detailed analysis and discussion of surface water monitoring results in the Resolution Project study area; Devils Canyon, Queen Creek, and Mineral Creek.

This report was prepared to support ongoing National Environmental Policy Act (NEPA) review process for the Resolution Project near Superior, Arizona. This report is an addendum to several previous reports prepared by Montgomery & Associates (M&A) that include detailed analysis and discussion of hydrochemical sampling results for surface water and groundwater in the Upper Queen Creek/Devils Canyon (QCDC) study area including:

Hydrologic test wells HRES-01, HRES-02, HRES-03, HRES-04, and HRES-05 were drilled and constructed during the period February 2 to March 11, 2004. The test wells were drilled evaluate lithologic and hydrogeologic conditions within the Apache Leap Tuff, and were terminated in the uppermost part of the Whitetail Conglomerate. Final test well construction was designed to permit hydrologic testing of the Apache Leap Tuff aquifer, and to provide access for long-term monitoring of groundwater level and groundwater quality for the aquifer.

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 technical memorandum was prepared to summarize modifications made to wells HRES-02, HRES-05, and HRES-10 in 2011.

This draft technical memorandum has been prepared to summarize results of drilling, construction, and development of groundwater production well RESPW-01. The well was installed to intersect mine workings on the 4400 Mine Level adjacent to Shaft No. 8 of the Magma Mine in order to dewater that level and overlying levels.
