The Lost Gunsight Mine you’re searching for isn’t actually in Death Valley—it’s located near Tecopa in the Kingston Range, about 60 miles southeast. The legend stems from Jim Martin’s 1849 silver discovery when he fashioned a rifle gunsight from nearly pure silver ore during the “Lost ’49ers” ordeal. The physical mine operated primarily between 1912-1928, extracting galena from Cambrian dolomite formations. Today it sits within protected wilderness, preserving both the geological evidence and artifacts that reveal how frontier mythology transformed into documented mining history.

The Lost ’49ers and Their Fateful Decision
In November 1849, as 107 wagons rolled toward California’s goldfields under Captain Jefferson Hunt’s command, a fateful disagreement erupted near Enterprise, Utah.
You’ll find the historical context reveals a critical choice: follow Hunt’s proven route along the Old Spanish Trail or attempt an untested desert shortcut promising twenty days saved. Hunt’s stark warning—you’d be “walking into the jaws of hell”—couldn’t dissuade those driven by gold fever and impatience with authority.
The breakaway group, later called the Lost ’49ers or Jayhawkers, lacked the mining technology and survival knowledge for what awaited them.
They’d traverse the Panamint Mountains and Death Valley‘s unforgiving terrain, burning their wagons for fuel and slaughtering oxen while Hunt’s disciplined party reached California safely ahead. The perilous 1850 emigrant journey would give Death Valley its ominous name, forever marking the region’s deadly reputation. After four months of exhausted travel through the desert, the survivors were starved and severely dehydrated.
Jim Martin’s Silver Discovery and the Birth of a Legend
While Jim Martin and his companions struggled through the Panamint Range, their attention fixed on immediate survival rather than mineral wealth, an unremarkable moment would spawn one of the American West’s most enduring legends.
When Martin’s rifle gunsight broke, he grabbed a nearby rock as replacement material. That rock proved to be nearly pure silver. After reaching Mariposa, Martin commissioned a gunsmith to craft a functional gunsight from the ore—a transformation that validated his find without sophisticated mining techniques or prospecting tools.
The silver gunsight‘s creation triggered three significant developments:
- Martin’s story spread rapidly among gold-seeking settlers
- Failed expedition attempts by Turner and Dr. French opened desert routes
- The legend intensified prospecting pressure throughout the 1860s
The discovery occurred as smaller groups became lost in the Dead Valley area during the challenging migration of October 1849. You’ll find this tale represents freedom’s double edge: opportunity discovered, yet forever lost. The prospecting booms of the 1880s brought hundreds of fortune seekers searching for the Lost Gunsight Mine’s location.
Location and Geological Features of the Mine
The Panamint Range’s western wall of Death Valley stretches 100 miles north-south through Inyo County, California, creating a formidable geological barrier where Martin’s discovery allegedly occurred.
You’ll find cartographic inaccuracies plague efforts to pinpoint the mine’s location, with coordinates ranging from the Kingston-Resting Springs Mining District near Tecopa to disputed sites at 35°50′54″N, 116°07′26″W.
The region’s mineralization patterns reflect typical Basin and Range Province geology—fault-block structures hosting Precambrian rocks with Cu-Ag-Zn-Pb deposits similar to the nearby Ibex Mine. The Ibex Hills themselves form a rugged, isolated mountain range within Death Valley Wilderness on National Park Service land.
Dr. Darwin French’s 1860 application of the “Panamint” term during his Gunsight Lode search established the area’s mining identity.
Telescope Peak’s 11,043-foot elevation dominates this rugged terrain, where early prospectors confronted both geographical isolation and geological complexity in their pursuit of silver-bearing formations. The Panamint Mountains contain vital springs within canyons that served as critical water sources for both Native travelers and gold prospectors traversing this unforgiving landscape.
Early Expeditions to Relocate the Silver Outcrop
Shortly after Jim Martin’s 1849 discovery reached Fort Tejon, Turner—who’d witnessed the original silver outcropping firsthand—organized the first documented recovery expedition with Dr. E. Darwin French in September 1850. Despite Turner’s direct knowledge, the expedition failed to relocate the site, revealing limitations in contemporary prospecting methods.
French mounted a larger-scale attempt in May 1860, leading approximately 15 Butte County men through systematic exploration:
- Established base camp 25 miles west-northwest of Furnace Creek near abandoned emigrant wagons
- Employed contemporary mining technology to assay promising formations throughout Death Valley
- Discovered rich silver deposits in the Coso Range as secondary compensation
The expeditions’ failures didn’t discourage further attempts. Dr. S.G. George organized his own 1861 party, while Jay Hitchens returned after ten years, demonstrating the legend’s persistent grip on prospectors seeking autonomy through mineral wealth. William Manly’s attempt to find the Gunsight ended in near-death after being lost without water for days.
Impact on Death Valley Mining Development
Though Jim Martin’s silver gun sight never led prospectors back to its original outcropping, the legend fundamentally transformed Death Valley’s role in California’s mining economy.
By 1860, organized expeditions from Sacramento and Oroville brought experienced miners with advanced prospecting tools into previously unexplored territories.
Dr. Darwin French’s dozen-man party systematically investigated canyons using mining techniques that revealed legitimate deposits in the Coso Range and Wild Rose Canyon.
The Noonday Mine alone generated nine million dollars, while infrastructure investments included a 12-mile railroad from Tecopa.
You’ll find that prospectors established permanent camps and arastres throughout the region, *shifting* from speculative searches to commercial operations.
The legend’s origins trace back to Captain Towne forging a silver gunsight at White Sage Flat during the harsh winter journey of 1850.
Dennis and John Searles identified gold and silver mineralization in the Slate Range, contributing to the expanding network of viable mining claims.
This sustained activity from 1849 through the 1860s positioned Death Valley as a significant mineral-producing district, vindicating early risk-takers’ exploration efforts.
The Actual Gunsight/Apex Mine Near Tecopa
You’ll find the actual Gunsight Mine—later consolidated as the Apex Mine—positioned at coordinates 35°50’34.56″N 116°7’21.71″W in the Kingston Range Wilderness near Tecopa, California, not within Death Valley proper.
Archival records establish this site operated within the Kingston-Resting Springs Mining District from 1865 through 1928, with its most productive period spanning 1912 to 1928.
The mine’s geological structure featured a lenticular galena ore body hosted in dolomite, with the vein composition changing from lead-rich surface deposits to carbonate ores at depth, valued between $60 and $400 per ton. The complex underground system included multiple working levels at 200 ft, 300 ft, 700 ft, 800 ft, and 930 ft depths, connected by extensive tunnels, crosscuts, and ore chutes.
Location and Geographic Setting
While the legendary Lost Gunsight Mine captured imaginations through tales of 1849 prospectors, the documented Gunsight Mine sits firmly on modern maps at the San Bernardino/Inyo county line, due east of present-day Tecopa.
This verifiable site, also called Apex Consolidated Mine, operates within the Kingston-Resting Springs Mining District, now part of the Kingston Range Wilderness.
The mine’s position reveals strategic placement within Basin and Range Province geological formations:
- Located 10 miles east of Death Valley National Park’s boundary
- Situated at the southern edge of the Nopah Range
- Positioned at Section 9, T20N, R8E, SBM coordinates
You’ll find it approximately 10 miles from Shoshone, accessible via the historic Spanish Trail route.
The rugged terrain demanded innovative mining techniques, with trails connecting multiple operational levels carved into the mountain’s facade.
Mine Structure and Geology
The Gunsight Mine’s ore bodies developed within Cambrian-age dolomite formations that served as ideal host rock for metallic mineralization. You’ll find lens-shaped galena deposits positioned along structural faults and fissures, where lead and silver concentrated through hydrothermal processes.
The mine’s workings extend through multiple levels—300, 700, 800, and 930 feet—following mineral veins that cut through dolomite underlain by Proterozoic shales and conglomeratic sandstones.
The region’s Basin and Range tectonics created N-S trending faults dipping 35-55 degrees westward, displacing ore bodies up to 30 feet. Quartz monzonite intrusions along thrust faults introduced additional metalliferous deposits of gold, copper, zinc, and tungsten.
You can trace these relationships through connected haulage tunnels where angled veins reveal the property’s complex geological history.
Present-Day Site Conditions and Wilderness Preservation
You’ll find several thousand feet of underground workings and an intact cabin at the Gunsight/Apex site, though its federal wilderness designation now limits access.
The mine’s location within Kingston Range Wilderness has preserved early 20th-century relics like ore boxes and structural remnants from the lead-silver operations.
This protected status means you’re viewing a frozen snapshot of Basin and Range mining history, where the site’s connection to Noonday Mine and shared infrastructure with Shoshone Mine created the operational complexity that contributed to its eventual abandonment.
Underground Workings and Remnants
Beneath Death Valley’s unforgiving terrain, several thousand feet of underground workings reveal the ambitious scale of operations at the Lost Gunsight Mine. Underground exploration uncovers multiple operational levels—the 200-foot, 300-foot, 700-foot, 800-foot, and deepest 930-foot level—connected by winze shafts and steep inclines reaching 60 degrees.
Archaeological artifacts document the miners’ ingenuity:
- Ore cars with intact chains and pivot mechanisms rest on original rails
- Handmade wooden nails and chutes demonstrate frontier craftsmanship
- A winch base with attached cable remains at the 800-foot station
Large stopes and drifts extend through converging ore sheets, though caved passages now block the original shaft and portal.
You’ll find the ladders extending hundreds of feet deemed unsafe, while dusty conditions preserve this testament to human determination in America’s harshest landscape.
Kingston Range Wilderness Status
Federal protection arrived at the Lost Gunsight Mine site when Congress passed the California Desert Protection Act in 1994, establishing the Kingston Range Wilderness under Public Law 103-433. You’ll find the Bureau of Land Management now manages this designated wilderness, with boundaries expanded through the 2019 Dingell Act.
The wilderness designation preserves wildlife habitat around perennial water sources in Amargosa Canyon, where year-round streams support bird densities markedly exceeding surrounding desert areas. This ecological conservation framework protects specialized ecosystems dependent on rare desert water availability.
The mine’s historical workings remain accessible through non-wilderness corridors like Sperry Wash and Kingston Wash, though extraction activities ceased under federal wilderness regulations.
You can obtain detailed maps from BLM offices in Needles or Barstow.
Frequently Asked Questions
What Happened to Jim Martin After He Made the Silver Gunsight?
After crafting the silver gunsight, you’d find Jim Martin returned in 1862—13 years later—to search unsuccessfully for the lode. Mining techniques couldn’t relocate it, though the tale’s historical significance sparked Death Valley’s prospecting boom, then Martin vanished from records.
How Much Silver Was Actually Extracted From the Lost Gunsight Mine?
You’ll find no recorded production figures for the Lost Gunsight Mine itself. Without ore processing or mineral valuation documentation in archival records, the actual silver extraction remains unknown—distinguishing legend from the documented Gunsight operations that followed decades later.
Can Visitors Legally Explore the Gunsight/Apex Mine Site Today?
You can legally hike to the site within Kingston Range Wilderness, but mining safety concerns and preservation efforts prohibit entering unstable underground workings. Federal wilderness protections allow observation only—no digging, collecting, or disturbing historic features.
Were Any Other Valuable Minerals Besides Silver Found at the Site?
Yes, you’ll find mineral diversity at the site beyond silver. Mining history records show lead as the primary ore, plus copper, gold, and zinc as secondary metals extracted during operations from 1912 to 1928.
Did Jim Martin Ever Return to Relocate His Original Silver Discovery?
No verified records confirm Martin ever returned. You’ll find mining legends and silver disputes obscure the truth—archival research shows companions like Turner searched unsuccessfully, but Martin himself apparently never led expeditions to relocate his original discovery.
