John Percival Jones

John Percival Jones (January 27, 1829 – November 27, 1912) was a prominent Anglo-American mining entrepreneur, capitalist, and long-serving politician whose career epitomized the intersection of Western mining booms, corporate investment, and national politics in the late 19th century. Known as one of the “Silver Senators,” Jones amassed significant wealth through silver mining in Nevada’s Comstock Lode before expanding his investments into California. His political influence as a U.S. Senator from Nevada for 30 years (1873–1903) amplified his role in promoting mining interests, free silver policies, and regional development.

Early Life and Arrival in the West

Born at “The Hay” in Herefordshire, England, Jones immigrated to the United States as an infant in 1829 with his family. He grew up in New York before heading west during the California Gold Rush. In 1849, at age 20, he arrived in California and settled in Trinity County in the northern part of the state. There, he engaged in placer mining, farming, and local affairs, serving as sheriff and justice of the peace in Weaverville. These early experiences in the Mother Lode region honed his skills in mining operations and frontier governance, though he did not achieve major wealth in California gold mining at this stage.

Rise in Nevada: The Comstock Lode and Crown Point Mine

Jones moved to Nevada in the mid-1860s amid the excitement of the Comstock Lode, the legendary silver discovery near Virginia City (then part of Utah Territory, later Nevada). In 1868, he became superintendent of the Crown Point Mine in Gold Hill, a key producer on the Comstock Lode. Under his management, the mine struck a rich ore body, propelling Jones to millionaire status and earning him the reputation as the Comstock’s first millionaire mine superintendent.

His heroism during a deadly 1869 fire on the Comstock further enhanced his stature. Jones was credited with brave actions that saved lives and property. This success, combined with his operational expertise, positioned him as a leading figure in Nevada’s mining industry. The Comstock’s deep, hardrock silver mining required substantial capital, corporate organization, and technological innovation—areas where Jones excelled as both manager and investor.

Political Career and the “Silver Senator” Era

In 1873, Jones was elected as a Republican U.S. Senator from the new state of Nevada, serving continuously until 1903—a remarkable 30-year tenure. He joined fellow mining magnate William Morris Stewart (another Comstock lawyer-turned-senator) in representing Nevada’s interests in Washington. Both became staunch advocates for free silver (bimetallism), opposing the gold standard and pushing policies favorable to Western mining states. Jones’s wealth and influence made him a powerful voice for silver producers nationwide.

Mining Investments in Nevada and California

Jones’s mining career extended beyond the Comstock. In Nevada, his Crown Point success provided the capital for further ventures. He invested in various Comstock properties and remained active as a capitalist even after entering the Senate.

Panamint City Stamp Mill
Panamint City Stamp Mill

His most notable California investment came in the mid-1870s with the Panamint silver district in the Panamint Range (now part of Death Valley National Park). In 1873–1874, rich silver outcrops were discovered in Surprise Canyon by prospectors (including former outlaws). Hearing of the excitement, Jones—fresh from Comstock riches—partnered with Senator Stewart to form the Panamint Mining Company. They invested heavily (reports vary from $250,000–$350,000 personally, plus millions raised from investors) to acquire controlling interests in key claims like the Wyoming and Wonder mines. They organized the district, built infrastructure (including a 20-stamp mill), and promoted the camp aggressively.

Panamint City boomed briefly to 1,500–2,000 residents in 1874–1875, becoming infamous for lawlessness (dozens of murders reported). Jones and Stewart floated stocks on the San Francisco Mining Exchange and cast bullion into heavy cubes to deter theft. However, the high-grade ore depleted quickly, and a devastating flash flood in 1876 destroyed much of the town. By 1877, operations collapsed amid a market panic, yielding little return despite massive investment. This bust highlighted the speculative risks of remote desert mining.

Jones also pursued broader California ventures tied to his mining interests. In 1874, he partnered with Colonel Robert S. Baker to develop Santa Monica as a seaside resort and potential port. He purchased a three-fourths interest in Baker’s Rancho Boca de Santa Monica ranch for $162,500 and built the Los Angeles and Independence Railroad (a narrow-gauge line from Los Angeles to Santa Monica, completed in 1875 without subsidies). Originally intended to connect to Inyo County silver mines (including Panamint) via Independence, financial strains from failing mines forced Jones to sell the railroad to Collis P. Huntington’s Southern Pacific in 1877. Santa Monica’s founding and early growth remain his most enduring California legacy.

Later Life and Legacy

After retiring from the Senate in 1903, Jones lived in comfort, dividing time between Washington, D.C., New York (where he owned a hotel), San Francisco (with a Turkish bath investment), and California properties. He pursued other interests, including early water reclamation ideas linked to what became Hoover Dam. He died in Santa Monica on November 27, 1912.

John P. Jones embodied the transition from individual prospecting to corporate mining capitalism in the American West. His Comstock fortune funded ambitious but often risky ventures like Panamint, while his Senate role shaped national mining and monetary policy. Though some investments (notably Panamint) ended in disappointment, his role in founding Santa Monica and promoting Western resource development left a lasting mark on California and Nevada history.

William Morris Stewart

William Morris Stewart (August 9, 1827 – April 23, 1909), often called the “Silver Senator,” was a prominent American lawyer, politician, and mining investor whose career intertwined deeply with the mining booms of California and Nevada. Known for his aggressive legal tactics, advocacy for free silver and mining rights, and involvement in high-profile (and sometimes controversial) ventures, Stewart amassed significant wealth through prospecting, litigation, and speculation before and during his long political tenure.

Early Life and Arrival in the West

Born in Galen, near Lyons, Wayne County, New York, Stewart was the oldest son of Frederick A. and Miranda Morris Stewart. His family moved to a farm in Trumbull County, Ohio, during his childhood, but he returned to Lyons for high school. In 1848, he entered Yale University but left after three semesters to join the California Gold Rush. Traveling via the Isthmus of Panama, he arrived in San Francisco in spring 1850 and headed to the gold fields near Nevada City, California. There, he prospected successfully, discovering the famed Eureka diggings and profiting enough to sell his interests at a substantial gain. This early success funded his shift from mining to law.

Legal Career and California Mining Ties (1850s)

Stewart studied law under John R. McConnell in Nevada City and was admitted to the bar in 1852. He served as district attorney of Nevada County in 1853 and briefly as acting attorney general of California in 1854. In 1855, he married Annie Elizabeth Foote (daughter of former Mississippi Senator Henry S. Foote) and moved to Downieville, California, in 1856, continuing his legal practice amid the region’s placer and quartz mining operations. His expertise in mining law—gained through litigation over claims, water rights, and ore disputes—laid the foundation for his later prominence.

Move to Nevada and the Comstock Lode (1859–1875)

The 1859 discovery of the Comstock Lode—one of the richest silver deposits in history—in what was then Utah Territory (soon Nevada) drew Stewart to Virginia City in 1860. He became the most prominent lawyer on the Comstock, specializing in mining litigation. He championed the “single ledge” theory (arguing the Comstock was one continuous vein), which influenced massive stakes in control of the lode. Stewart estimated earning $500,000 from four years of such cases, amid litigation costing up to $10 million overall. His aggressive style—sometimes described as not always strictly ethical—earned him a fearsome reputation.

Politically, Stewart helped shape Nevada: he served on the territorial council (1861), attended the 1863 constitutional convention, and became one of Nevada’s first U.S. Senators upon statehood in 1864 (serving until 1875). He drafted key national mining laws (1866 and 1872) formalizing Western practices like claim location and free access to public lands. He also contributed to the Fifteenth Amendment and supported railroad interests.

Investments and Controversies in Mining

Beyond law and politics, Stewart invested directly in mining:

  • Comstock Lode: He participated as a capitalist after his legal work, profiting from the silver boom.
  • Emma Mine (Utah, 1870s): Stewart promoted this silver mine in Little Cottonwood Canyon to British investors, raising millions. Accusations of fraud arose when the mine proved depleted or overvalued; he and partners sold shares profitably, tarnishing his reputation.
  • Panamint City (California, 1873–1877): In late 1872/early 1873, prospectors (including outlaws) discovered rich silver in Surprise Canyon, Panamint Range (near Death Valley), while searching for the legendary Lost Gunsight Mine. Stewart partnered with fellow Nevada Senator John P. Jones (both dubbed “Silver Senators” for their mining ties) to form the Panamint Mining Company (capitalized at $2 million). They invested heavily—over $250,000–$350,000—buying claims (e.g., Wyoming, Wonder, Challenge), arranging amnesty for bandit discoverers (with restitution to Wells Fargo), and promoting the boom. Panamint City swelled to 1,500–2,000 residents with mills and infrastructure, but ore depleted quickly, and a 1876 flash flood devastated the town. The venture collapsed by 1877, adding to Stewart’s controversial legacy.

Stewart’s mining pursuits often blended speculation, promotion, and politics, drawing criticism for prioritizing profit and development over restraint.

Later Career and Legacy

After leaving the Senate in 1875 (due to financial pressures against rival William Sharon), Stewart practiced law in San Francisco and pursued unsuccessful mining schemes. He represented clients in scandals (e.g., William Sharon’s divorce) and briefly joined the Silver Party (1892–1899) to advocate remonetizing silver, editing the Silver Knight newspaper. Rejoining Republicans in 1900, he returned to the Senate (1887–1905), championing Western irrigation, mining safety, and opposing figures like John Wesley Powell on land policy.

In 1905, at nearly 80, Stewart moved to the Bullfrog mining district in southern Nevada, opening a law firm and dabbling in ventures. He died in Washington, D.C., in 1909, leaving a fortune from mining and law (estimated at millions earlier). Inducted into the Hall of Great Westerners (1964), Stewart embodied the rugged, opportunistic spirit of the mining West—shaping laws that enabled its development while embodying its excesses and controversies. His investments in California (early gold fields, Panamint) and Nevada (Comstock, later camps) helped fuel booms that transformed the region, for better and worse.

Keane Wonder Mine

The Keane Wonder Mine (also known as Keane Wonder Mine and Mill) stands as one of the most significant and best-preserved historic gold mining sites in Death Valley National Park, California. Located in the Funeral Mountains on the eastern side of Death Valley, it represents a rare success story amid the region’s typically short-lived and unprofitable mining ventures during the early 20th-century gold rushes.

Jack Keane discovered an immense ledge of free milling gold ore in 1904 in the northern Funeral Range in Death Valley. The Keane Wonder Mine was one of the most productive gold mine in the area. www.nps.gov/parkhistory/online_books/deva/section4b3.htm

Discovery and Early Development (1903–1906)

Prospecting in the Funeral Mountains dated back to the 1860s, but no major strikes occurred until the early 1900s. In December 1903, two prospectors from the nearby supply camp of Ballarat—Jack Keane, an Irish immigrant who had been struggling in the desert for years, and Domingo Etcharren, a one-eyed Basque butcher—explored an area known as Chloride Cliffs, initially targeting silver deposits.

After months of unsuccessful work on a ledge, Etcharren grew discouraged and left. Keane persisted and, by chance (some accounts credit Etcharren noticing a quartz outcropping as he departed), discovered a rich vein of free-milling gold ore—high-quality ore that could be processed relatively easily. This was Keane’s first major find after nearly a decade of hardship, leading him to name it the “Keane Wonder” (or “Keane’s Wonder”) in astonishment and optimism.

The pair quickly staked and patented eighteen claims to secure the site. They sold options on the property to investors, including a New Yorker named Joseph DeLamar, but initial deals fell through—partly due to competing discoveries elsewhere in the region (like the Bullfrog boom to the north). It wasn’t until 1906 that serious development began when investors, including John F. Campbell and later Homer Wilson (an experienced miner from California’s Mother Lode), purchased the claims for sums reportedly ranging from $150,000 to $250,000 before significant extraction.

As part of the agreements, Keane and Etcharren retained stakes: Keane became president of the Keane Wonder Mining Company, and Etcharren served as secretary.

Peak Operations and Infrastructure (1907–1912)

Under new ownership, the mine rapidly expanded into a full-scale operation. By 1907, it featured:

  • A 20-stamp mill at the lower site to crush and process ore.
  • An ice plant to combat the extreme desert heat.
  • Support facilities for a mining camp, including worker housing.

The site’s steep, rugged location high on the mountainside posed major logistical challenges for transporting ore downhill to the mill. To address this, the company constructed a remarkable mile-long aerial tramway (approximately 1 to 1.5 miles, with about 1,000–1,500 feet of vertical drop) in 1907. This gravity-powered system used wooden towers, cables, and metal ore buckets to move material efficiently from the upper mine workings to the lower mill.

At peak production (roughly 1908–1911), the tramway transported up to 70 tons of ore per day (some sources note higher daily figures in short bursts). The ingenious design reduced costs dramatically compared to pack mules or manual labor on the treacherous slopes, making the operation profitable despite Death Valley’s harsh conditions (extreme heat, water scarcity, and isolation). The Keane Wonder became known as the “King of the Desert” in local papers like the Rhyolite Herald, and it was the most productive and longest-operating mine in the Funeral Mountains region—outlasting many flash-in-the-pan camps.

The mine yielded substantial gold (with some silver), with total output estimates ranging from $750,000 to over $1.1 million (equivalent to tens of millions in modern dollars) between 1904 and 1917, with the bulk from 1907–1912. It was one of the few truly profitable gold mines in Death Valley during this era.

Decline and Closure (1912–1942)

By 1912, easily accessible high-grade ore was largely depleted, leading to financial struggles and reduced activity. The mine was sold amid speculation that it was “played out.” Intermittent small-scale operations continued, but major production ended around 1916–1917. A final revival attempt ceased by 1942.

Post-Mining History and Preservation in Death Valley National Park

The National Park Service acquired the claims in the 1970s as part of Death Valley’s expansion and protection (Death Valley became a national monument in 1933 and a national park in 1994). The site preserves over 18,000 mining features park-wide, with Keane Wonder exemplifying early 20th-century engineering and hardship.

The area closed from 2008 to 2017 for safety reasons, including structural stabilization of unstable mine workings, hazard mitigation (e.g., after a fatal fall into a shaft in 1984), and soil sampling for contamination. Restoration focused on the aerial tramway towers, upper and lower terminals, and other structures. It reopened in November 2017 and is now a popular hiking destination via the Keane Wonder Mine Trail (a strenuous 3+ mile round-trip with significant elevation gain).

Keane Wonder Mine Trail Map

Today, visitors can view remnants including:

  • Foundations of the stamp mill.
  • Mine adits and shafts (do not enter—unsafe and illegal).
  • The iconic line of wooden tramway towers and terminals stretching up the mountainside, with some ore buckets still in place.

The aerial tramway remains a highlight: a testament to innovative engineering that overcame the site’s extreme topography and enabled the mine’s success. It symbolizes how infrastructure could turn marginal deposits profitable in one of Earth’s harshest environments.

The Keane Wonder Mine offers a tangible link to Death Valley’s mining heritage—boom-and-bust cycles, perseverance, and the fleeting allure of gold in the desert.

The Comstock Lode – Nevada State Historic Monument

The Comstock Lode stands as one of the most significant mining discoveries in American history: the first major silver deposit found in the United States. Located beneath the eastern slope of Mount Davidson in the Virginia Range, near what became Virginia City, Nevada (then part of western Utah Territory), it transformed the region from a sparsely populated frontier into a booming industrial center. The lode’s riches fueled the development of Nevada as a state, bankrolled much of San Francisco’s growth, influenced national monetary policy debates, and advanced deep-level mining technology.

Early Discoveries and the Path to 1859

Placer gold mining began in the area as early as 1850, when Mormon emigrants led by Abner Blackburn found gold in Gold Canyon (near present-day Dayton, Nevada). Small-scale placer operations continued through the 1850s, with miners washing gold from streams flowing down from the Virginia Range. These efforts were modest and overshadowed by the California Gold Rush.

In 1857, brothers Ethan Allen Grosh and Hosea Ballou Grosh (experienced prospectors from Pennsylvania) reportedly discovered rich silver-gold veins while searching the area. They documented promising samples but tragically died before recording formal claims—Ethan from a mining accident and Hosea from frostbite after a winter trek. Their knowledge passed to others indirectly.

By early 1859, prospectors including Peter O’Riley and Patrick McLaughlin were working claims in Six-Mile Canyon and Gold Canyon. On June 12, 1859 (the generally accepted date of the major “rediscovery”), they uncovered a rich vein of gold mixed with heavy blue-gray clay while digging for water to process placer gold. The clay proved frustrating until assayed and revealed as rich silver sulfide ore—marking the true start of the Comstock Lode.

Henry Tompkins Paige Comstock (“Old Pancake”), a talkative Canadian prospector and sheepherder, quickly inserted himself into the discovery. He claimed the ground for “grazing” and pressured the finders into giving him and partner Emanuel “Manny” Penrod shares. Though Comstock contributed little technically and sold his interests cheaply soon after (dying poor later), the lode bore his name.

News of the strike spread rapidly, sparking the “Rush to Washoe” (named for the Washoe Valley region). Thousands poured in from California, creating instant camps.

Boom Period and Development (1859–1870s)

The Comstock Lode stretched about 2.5–3 miles along the base of Mount Davidson, with ore bodies in narrow, steeply dipping veins that required deep underground mining. Initial placer and shallow diggings gave way to hardrock operations.

  • Towns and Infrastructure: Virginia City (founded 1859) and Gold Hill exploded in population, reaching peaks of 20,000–25,000 by the mid-1870s. Virginia City became the most important city between San Francisco and Denver, with saloons, theaters, newspapers (including the Territorial Enterprise), churches, schools, and an opera house. Other settlements included Silver City and Dayton.
  • Mining Challenges and Innovations: Early miners faced flooding, cave-ins, and unstable ground. German engineer Philipp Deidesheimer invented the square-set timbering system in 1860, allowing safe excavation of large ore bodies. Deep shafts reached over 3,000 feet by the 1880s. Adolph Sutro engineered the Sutro Tunnel (completed 1878), a 4-mile drainage and transport tunnel that relieved flooding and cut costs dramatically.
  • Economic Control: The Bank Crowd (led by William Sharon of the Bank of California and William Ralston in San Francisco) dominated early financing, mills, and stock manipulation on the San Francisco Mining Exchange. They controlled much of the early production but faced competition.
  • Key Bonanzas:
    • Ophir (early producer until ~1864).
    • Crown Point (major strike in 1871).
    • The Big Bonanza (1873) in the Consolidated Virginia and California mines—discovered by the Bonanza Firm (or “Bonanza Kings”/”Silver Kings”): Irish immigrants John William Mackay, James Graham Fair, James Clair Flood, and William S. O’Brien. This massive ore body (54 feet wide at points) produced over $100 million (hundreds of millions today) and made them among the richest men in the world.

Mark Twain (Samuel Clemens) worked briefly as a miner before becoming a reporter for the Territorial Enterprise, drawing on Comstock experiences for Roughing It.

Peak Production and Decline (1870s–1880s)

Peak output came in 1877–1878, with annual production exceeding $35 million ($14–21 million gold and silver combined, equivalent to over $1 billion today). From 1859 to the early 1880s, the district yielded roughly $400–500 million in metals (at then-current prices), including estimates of ~192–200 million ounces of silver and ~8–8.3 million ounces of gold. About 7 million tons of ore were extracted by 1880, with 57% silver value and 43% gold.

The lode’s riches helped finance the Union during the Civil War (prompting Nevada’s rushed statehood in 1864 for electoral votes and senators like William Morris Stewart and John P. Jones). Wealth flowed to San Francisco, building infrastructure and mansions.

By the late 1870s, rich bonanzas depleted, flooding worsened, and costs soared. Production declined sharply after 1880, though small-scale mining continued into the 20th century (sporadic until the 1940s, with minor revivals).

Nevada State History Marker #13

Nevada State Historical Markers identify significant places of interest in Nevada’s history. The Nevada State Legislature started the program in 1967 to bring the state’s heritage to the public’s attention with on-site markers. Budget cuts to the program caused the program to become dormant in 2009. Many of the markers are lost of damaged.

Near this spot was the heart of the Comstock Lode, the fabulous 2 ½ mile deposit of high-grade ore that produced nearly $400,000.00 in silver and gold.  After the discovery in 1859, Virginia City boomed for 20 years, helped bring Nevada into the union in 1864 and to build San Francisco.

Several major mines operated during the boom.  Their sites are today marked by large yellow dumps, several of which are visible from here – the Sierra Nevada a mile to your left, the Union, Ophir, Con Virginia and, on the high hill to the southeast, the combination.  The Lode was worked from both ends, north up Gold Canyon and south from the Sierra Nevada Utah mines.

Rochester Nevada – Pershing County Ghost Town

Rochester, Nevada, is a historic ghost town and former mining camp located in Rochester Canyon within the southern Humboldt Range in Pershing County, Nevada. Situated roughly 10-15 miles southeast of Interstate 80 (near the Oreana exit) and about 110 miles east of Reno, it lies in a narrow, steep canyon that once supported a booming silver and gold mining community.

Early Discovery and Initial Development (1860s–Early 1900s)

The Rochester district was first discovered in the early 1860s by prospectors from Rochester, New York, who found gold and silver deposits in the canyon. They named the area after their hometown. Small-scale mining occurred during this period, including work at sites like the Relief Mine in the southern part of the range. However, these early efforts yielded limited success, and the district remained relatively insignificant for decades, with only sporadic activity through the 1870s and into the early 20th century.

In 1905, Charles E. Stevens located claims on Nenzel Hill at the head of Rochester Canyon. These claims later passed to Joseph F. Nenzel.

Lower Rochester, Nevada 1913
Lower Rochester, Nevada 1913

The Boom Period (1912–1920s)

The true transformation came in 1912, when Joseph Nenzel shipped a small lot of float ore that assayed surprisingly high values. This led to the discovery of rich silver-bearing veins, sparking a major boom. Word spread quickly, and by 1913, the canyon’s population swelled to around 2,000 people.

The town developed in sections due to the steep terrain:

  • Upper Rochester (also called Old Town or Rochester Heights) sat higher up the canyon.
  • Lower Rochester was laid out on November 20, 1912, lower in the canyon and became the main hub, hosting the original post office.

Additional settlements included East Rochester and areas like Packard.

Two major companies drove operations:

  • The Rochester Mines Co. built an all-slime cyanidation mill starting at 100 tons per day (later expanded to 160 tons).
  • The Nevada-Packard Mines Co. constructed a 120-ton mill. In 1917, the Rochester Combined Mines Co. erected a $300,000 mill at Packard, though it operated briefly before shutting down (equipment later moved to Candelaria in 1922).

The district produced valuable silver, gold, copper, and lead, with estimates of total output ranging from $6 million to $10 million (primarily silver) during the main boom years from 1912 to 1928. Peak activity occurred in the mid-1910s, with the Rochester Mines Co. as a principal producer (facing but avoiding major apex litigation through compromise and consolidation into the Rochester Silver Corporation in 1920).

Decline and Ghost Town Status

Operations declined sharply in the late 1920s. The Rochester Silver Corporation ceased major work by 1929, and equipment was sold. Limited activity continued into the 1930s (e.g., the Buck and Charley Mine under the Rochester Plymouth Mines Co. in 1936), but the town faded as ore values dropped and the boom ended.

By the mid-20th century, Rochester had become a ghost town, with scattered ruins, mill foundations, and remnants stretching over two miles through the canyon.

Role in Pershing County History

Rochester played a significant role in the mining heritage of Pershing County, one of Nevada’s key mining regions. Pershing County—formed on March 18, 1919 (the newest county in Nevada, carved from Humboldt County and named after General John J. Pershing of World War I fame)—has long relied on mining and ranching. The area was part of early westward expansion routes like the Humboldt Trail.

Rochester’s 1912–1920s boom stood out as one of north-central Nevada’s most successful mining camps during a period when many districts struggled. Its production contributed to the region’s economy and highlighted Pershing County’s silver and gold potential in the Humboldt Range.

While the historic Rochester town is abandoned, modern mining revived in the district. The Coeur Rochester Mine (an open-pit heap-leach silver-gold operation) began in 1986, paused from 2007–2010, and resumed in 2011. It remains the largest employer in Pershing County today, building on the legacy of the early 20th-century discoveries.

Rochester exemplifies Nevada’s classic boom-and-bust mining cycle: modest beginnings, a dramatic silver rush, rapid growth, and eventual decline—leaving behind a poignant ghost town that attracts historians, explorers, and off-road enthusiasts.
