A former Au-Ag-Mn-Cu-Pb occurrence/mine located on 12 claims patented by the Home Copper Co.(1901), in the NW¼ sec. 19, T4S, R29E, G&SRM, 2.5 miles W of Morenci. Located ½ miles NW of mouth of Pinkard Gulch at the head of a small gulch draining directly into Eagle Creek; next gulch N of Gold Gulch on the E side of Eagle Creek. Discovered in 1901 by the Home Copper Co. Property consist of 30 unpatented claims totaling 600 acres plus a 150 acre mill site. Produced 1904-1915 and 1921-1937. Owned by Mr. D. M. Cansler (1941). Operators included the Home Copper Company; John C. Molder; New York and Arizona Gold and Copper Company; and Mr. G.I. Pace.

Mineralization is tabular and irregular ore bodies (includes 4 ore bodies of which the Buzzard Shadow is the easternmost), hosted in the Longfellow Limestone and the Morenci Shale (quartzite). A well-defined fissure vein lies between crushed limestone stained by manganese in the hanging wall and porphyry in the foot wall. The ore zone is 1.22 meters wide, strikes E-W and dips vertically. Gold occurs free as well as combined in Cu & Fe sulfides. Associated rock unit is the Morenci Granite Porphyry and the Tertiary Coronado Quartzite. Ore control was an ENE-trending fissure. Ore concentration was supergene enrichment along well-defined fissures. Alteration is distinct contact metamorphic zone between limestones and porphyry associated with a hardening of sedimentary layers and substantial development of epidote and magnetite. Associated rocks include Tertiary quartz monzonite. Local rocks include Early Tertiary to Late Cretaceous granitic rocks.

South of the zone between Coronado Ridge and Gold Gulch Fault Blocks. Area structures include NE-trending granite porphyry dikes; alternating sandstone and shale beds form irregular areas almost entirely surrounded by Morenci Granite Porphyry. Longfellow Limestones are extensively exposed in this region. Morenci porphyry is not much altered but is greatly disintegrated. Principal regional porphyritic intrusions parallel planes of sedimentation, which dip 10-30SW. Regional faulting occurred prior to intrusion and mineralization.

Tectonic component is the Gold Gulch Fault Block.

Workings include surface and underground openings comprised of 3 tunnels (100, 450 & 600 feet respectively) plus the Lillian tunnel of 1,800 feet; 5 shafts (including the 260 foot Argentine shaft, 80 foot Louise shaft & the 72 foot Jensen shaft); small stopes and pits plus winzes to 100 feet deep. Free-milling Au ore occurs on surface.
