The proponent proposes to test drill in 4 locations for mining exploration.

The Coconino National Forest, Land and Resource Management Plan defines the direction for managing the Forest for the next 10 to 15 years. The Forest Plan provides for integrated multiple-use and sustained-yield of goods and services from the Forest in a way that maximizes long-term net public benefits in an environmentally sound manner.

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.

Yellow-billed cuckoo surveys at four sites in the vicinity of the Resolution Copper Project conducted in 2015. Surveys were conducted at the Whitlow Ranch Dam, two portions of Devils Canyon, and one segment of Mineral Creek, all in Pinal County, Arizona.

The chemical composition of natural water is derived from many different sources of solutes, including gases and aerosols from the atmosphere, weathering and erosion of rocks and soil, solution or precipitation reactions occurring below the land surface, and cultural effects resulting from human activities.

This report presents the results from a simulation model designed to predict the chemistry of water that will be collected in the underground workings of the Resolution Copper Project mine.

The Sugarloaf fault is a slightly arcuate, northwest-southeast trending fault located near the junction of Mesquite Wash and Sycamore Creek. The fault was identified by Fugro (1981), which considered the fault in itsMCE analysis for Stewart Mountain Dam because of the evidence for possible Quaternary activity along the structure.

The smallest geomorphic offsets along a 35 km section of the San Andreas fault in the Carrizo Plain vary from 7 to 10 m. Our three-dimensional excavation of alluvial deposits a few km southeast of Wallace Creek confirms that at least 6.6 to 6.9 m of dextral slip occurred there during the latest large earthquake, in 1857.

The spatial and temporal distribution of fault slip is a critical parameter in earthquake source models. Previous geomorphic and geologic studies of channel offset along the Carrizo section of the south central San Andreas Fault assumed that channels form more frequently than earthquakes occur and suggested that repeated large-slip earthquakes similar to the 1857 Fort Tejon earthquake illustrate typical fault behavior. We found that offset channels in the Carrizo Plain incised less frequently than they were offset by earthquakes.
