The proposed action would directly affect corner monuments that could lead to the loss of ability to effectively determine boundaries between public and private land. However, the proposed action includes design of a resurvey and control network to preserve the ability to reestablish landownership boundaries. Mineral survey fractions (5.5 acres) would be impacted by mining operations and would be sold to Rosemont Copper under the Small Tracts Act, relieving the Coronado of management responsibilities. Under the proposed action and other action alternatives, direct impacts would occur to the following lands: 1,212 to 1,369 acres of private land, 6,122 to 7,208 acres of land managed by the Coronado, 3 to 14 acres of Bureau of Land Management administered land, and 93 to 138 acres of Arizona State Land Department land administered as a State Trust.

The proposed action would result in a change from fully capable of supporting grazing activities to partially capable on 4,684 acres of the Rosemont grazing allotment, 280 acres of the Thurber allotment, 88 acres of the Greaterville allotment, 18 acres of the DeBaud allotment, 155 acres of the Helvetia allotment, and 0 acres of the Stone Springs allotment. The proposed action would result in a change from fully capable to not capable on 950 acres of the Rosemont grazing allotment (the area represented by the mine pit). A total reduction of 1,146 animal unit months would occur. Fifteen stock ponds and 63 springs would be lost. Mitigation would replace lost manmade water sources.
