This report is an addendum to the report “Pima Pineapple Cactus Survey: Proposed Rosemont Project Santa Rita Road Alignment,” dated December 18, 2009, produced by WestLand Resources, Inc. (WestLand) for Rosemont Copper Company (Rosemont). Approximately 38 acres of additional lands (Addendum Area) were subsequently added adjacent to the alignment, near a “pinch point” (a narrow connection of Rosemont Holdings between other privately owned lands) around the old Helvetia Townsite, in portions of Sections 22 and 23, Township 18 South, Range 15 East, Gila and Salt River Base Meridian (Figure 1). Figure 2 depicts the location of the pinch point covered by this survey, as well as a pinch point location covered by the original survey. At the request of Rosemont, WestLand surveyed the Addendum Area for Pima pineapple cactus (Coryphantha scheeri var. robustispina; PPC).
