Location: The LPH South prospect is at an elevation of about 7,200 feet about 0.1 mile southeast of peak 7905. It is northeast of the center of section 21, T. 17 N., R. 7 E., in the Copper River Meridian. The location is accurate.
Geology: The LPH South occurrence consists of zinc- and lead-rich massive sulfides about 800 feet above and one-third mile northeast of the PP2 prospect (MH345). Like the nearby LP prospect (MH341), mineralization is in the upper Lagoon unit metavolcanic rocks. Five samples representative of the sulfide variations average 6.1 percent zinc, 4.0 percent lead, 0.2 percent copper, 52 grams of silver per ton, and no gold (Dashevsky and others, 2003).
Workings: Only surface examinations and prospecting has been done at this occurrence.
Age: The Drum unit, which is part of the metamorphic sequence that includes the rocks at this deposit, has been dated at the Devonian-Mississippian boundary on the basis of one SHRIMP U-Pb zircon age of 359 +/- 6 Ma at the nearby DD South prospect (MH325) (Dashevsky and others, 2003).
Alteration: The metavolcanic rocks have been subjected to quartz-sericite-pyrite alteration.
