The Lippincott Mine (also known as the Lead King Mine) is a historic lead-silver mine located in the remote southwestern corner of Racetrack Valley within Death Valley National Park, California. Situated in the Ubehebe Mining District on the ridge separating Racetrack Valley from Saline Valley, the site represents one of the area’s more productive small-scale mining operations in the early-to-mid 20th century. Today, it features scattered ruins, adits (horizontal mine entrances), tailings piles, and remnants of mining infrastructure, though much has deteriorated over time. Visitors often access it via rough off-road routes, including the infamous Lippincott Mine Road.
Discovery and Early Development (1906–1910s)
The Lippincott Mine was discovered in 1906, with significant development work beginning around 1908. Located in a harsh, water-scarce desert environment, the mine targeted rich lead-silver deposits (primarily galena ore). Early ore samples showed impressive grades, often yielding around 42% lead and 8 ounces of silver per ton, making extraction economically viable despite the remote location.
The mine saw its most productive period during World War I, when demand for lead (used in ammunition and other wartime materials) surged. Miners reportedly used the flat, dry surface of the nearby Racetrack Playa as an improvised landing strip for small aircraft, aiding in supply transport and oversight.
World War II Era and Post-War Operations (1940s–1950s)
Operations ramped up again during World War II, with development of the Lead King Mine (under the Lippincott family) beginning in May 1942. A small crew of about eight miners extracted high-grade silver-lead ore, which was trucked out to Goldfield, Nevada, then railed to smelters in Utah. Only the richest ore was shipped due to challenging logistics — the silver was particularly valuable for wartime storage batteries.
Despite high ore quality (some reports cite up to 63% lead and 35 ounces of silver), federal restrictions shut down operations during the later war years as part of resource conservation efforts. The Lippincott family resumed work from 1946 to 1951, constructing additional infrastructure like a mine camp with wood and tarpaper cabins, an ore tipple, and possibly a tramway system.
Water scarcity remained a major challenge — supplies had to be trucked in over long distances — and this likely contributed to the eventual closure. Limited activity may have continued sporadically into the 1970s under later owners like George Lippincott Jr.’s Polaris Battery Company, which considered further exploration in 1974.
Legacy and Modern Significance
The Lippincott Mine is now part of Death Valley National Park, where all mining claims are inactive, and the site is protected as a historic resource. Ruins include adits (some gated for bat protection), scattered timbers, old vehicle parts, and tailings piles — visitors should avoid disturbing soil or inhaling dust due to potential residual lead contamination.
The mine’s access road — the steep, narrow, and extremely challenging Lippincott Mine Road (also called Lippincott Pass) — was originally built in 1906 to reach the site. This 7-mile route from Saline Valley to Racetrack Valley features sheer drop-offs, tight switchbacks, and rough terrain, making it one of Death Valley’s most notorious 4WD trails (high-clearance 4WD with experienced drivers only; uphill traffic has right-of-way).
The Lippincott Mine stands as a testament to the tenacity of early 20th-century prospectors in one of the harshest environments on Earth, contributing to the broader mining history of Death Valley that includes gold, silver, borax, and other metals. While not as famous as sites like Rhyolite or the Keane Wonder Mine, it remains a fascinating, off-the-beaten-path destination for adventurous visitors exploring Racetrack Valley’s moving rocks and remote wilderness.
