The General Mining Act of 1872 encourages exploration, claiming and mining of valuable mineral deposits by U.S. citizens of “ordinary prudence” within public lands that are unclaimed and open for mineral entry.[1] The Diggings website states that 3,856,269 mining claims have been recorded within the U.S., of which about 10 percent are currently active. The U.S. Geological Survey (USGS) lists 139,591 records of mines in North America with California leading the nation with its inventory of 25,673—more than double that of the runner up, Nevada.[2] However, the majority of these mines located throughout the U.S. were closed or abandoned long ago.

Numbers aside, the statute is considered by its detractors as archaic, in that it imposed little, if any, regulation in an effort to encourage the development and exploitation of the nation’s mineral resources. Opponents argue that the law provides a “free ride” for mining interests as no royalty has ever been levied on profits earned on metallic minerals over the nearly 150 years the act has been in place. It is estimated that $400 billion worth of gold and other lucrative minerals have been extracted in public lands without the American public receiving a dollar in return even though $1 billion of metal continues to be mined annually.[3]

In addition, the per-acre patent fees allowing for the outright purchase of mineral bearing of public lands—originally set at $2.50 for placer claims and $5 for lode claims while patenting was active, had not been raised since President Ulysses S. Grant first enacted the law. Although Congress imposed a moratorium on mineral patent applications on October 1, 1994 and no new patents have been issued since, mining watch dog groups argue that more than three million acres of public land have been “given away” for a pittance to foreign and domestic mining entities since 1867.[4] For instance, Canadian-owned Barrick Gold Corporation, who owns 75 percent of gold mining interests in Nevada, secured patents for over 1,800 acres of public land in 1994 just before mineral patenting had ended for around the price of $9,000—at the time estimated to yield over $10 billion worth of gold. In 2018 alone, Barrick’s worldwide operations generated $7.24 billion and provided their shareholders with a 33 percent increase in annual dividends.[5]

More perplexing is the fact that lawmakers have mostly failed to amend or modernize the 1872 law on these and other key issues. For instance, multinational mining corporations (many Canadian and foreign owned) operate within U.S. public lands without paying a cent on gold, silver, copper and the other valuable metallic minerals from which they profit most handsomely.[6] In contrast, the federal government collects annual royalties from 8 to 17 percent from corporations extracting coal, oil and gas within U.S. public land and waters—representing billions of dollars in royalties. The Pew Charitable Trusts’ Campaign for Responsible Mining estimates the federal government, along with taxpayers loses, at minimum, $160 million annually by failing not to impose similar levies on the hardrock metallic mining industry.[7]

Some bold U.S. lawmakers have sought to reform the industry’s egregious tax breaks and hefty federal subsidies, dubbed “reverse royalties,” beginning as early as the mid-1860s—but with little success. The late Arkansas Senator Dale Bumpers had an ongoing annual debate on this divisive issue with Nevada Senator Harry Reid over an eight-year period beginning in the early 1990s. It should be noted that both Senators are Democrats. Reid, born and raised in Searchlight, Nevada, a dusty gold town sixty miles south of Las Vegas, explains his hardline and unrelenting support of the mining industry.[8] Reid’s opponent, Bumpers, considered the 1872 law to be “a license to steal and a colossal scam.” Bumpers fought hard during his Senate tenure to see the act reformed—but to no avail—having stated that members of Congress “who perpetuated this unbelievable scam are never held accountable, because the public knows little, if anything, about the abuse.”[9]

Although several bills have been introduced in recent years seeking to impose royalties on corporate mining profits—including one unsuccessful bid in 1993 by former Secretary of the Interior Bruce Babbitt—mining special interest groups such as the National Mining Association have also lobbied hard and very successfully to keep bills from passing, arguing that they pay their share of taxes and provide rural jobs. Babbitt’s push fell flat after Reid publicly opposed his bill along with another one that would have eliminated a tax break for corporate mining companies—saving them around $327 million a year in taxes.[10] As long as Reid remained in office he would continue to thwart any similar bill that came his way.

A later effort to reign in industrial mining activities occurred in 2007 when the House of Representatives passed The Hardrock Mining and Reclamation Act that would, if enacted, levy a 4 percent royalty on existing mining at unpatented claims and 8 percent on any new mining operation. Private or previously patented claims were to be exempt. Seventy percent of the royalty fees were to be set aside to remediate abandoned mining claims with the remaining 30 percent given out as aid to communities negatively affected by such activities. Even the Bush administration toyed with the idea implementing royalties on metal mining production.[11] In contrast, during his 2007 presidential election campaign, then Senator Barrack Obama balked at imposing royalties on mining interests commenting, “legislation that’s been proposed places a significant burden on the mining industry and could have a significant impact on jobs.”[12] Nevada, as it turned out, is a crucial swing state. The U.S. Senate eventually killed the bill in 2009. Another version of this bill similarly died in 2011.

Senator Tom Udall (D-NM) and Chairman of the House Natural Resources Committee Raúl Grijalva (D-AZ) have co-sponsored a reform bill in 2019 that would require a 12.5 percent royalty on any new hardrock mining operation and an 8 percent royalty on existing ones—making more than $50,000 in annual income. With this bill, 25 percent of the collected revenues would go to the state where the mine is located and the rest will supplement a federal reclamation fund.[13]

Notably, eighteenth and early nineteenth century mining operations were miniscule in scale compared to today’s open pit cyanide heap leach operations. Consider the massive scale of the largest gold mine in North America—the Goldstrike Mine owned by Barrick Gold Corporation—geographically positioned along the microscopically gold-rich Carlin Trend of northeastern Nevada. The company’s website states that the “ultimate pit will measure approximately two miles east to west, 1.5 mi[les] north to south, and have an average depth of approximately 1,300 ft.”[14]

Regardless of their physical footprints, many smaller historical mines have resulted in lingering environmental damage, dangerous physical safety hazards and, at times, staggering ecological devastation. Thousands of historic, abandoned small-scale mining operations remain physically accessible and many require extensive environmental site remediation. With owners long gone or bankrupt, the federal government and consequently, the taxpayer, are left to foot the bill.

The Bureau of Land Management (BLM) manages these abandoned extractive follies on public lands throughout the West. Although the actual number of historic mining sites in the California Desert District is unknown, a 2014 USGS study estimates that there are 22,730 abandoned mine sites with 79,757 individual features located across thirty-five million acres of arid lands of central and southern California. The BLM’s Abandoned Mine Lands (AML) program whose mission is to “mitigate and remediate hard rock AML sites on or affecting public lands” suggests that within the Mojave Desert region there are 17,060 AML sites alone that require further study and possible remediation.[15]

It should come as no surprise that the 1872 act did not include a requirement for post-operational mining reclamation—the idea was simply unheard of at the time. It would take one hundred years—with the passing of the Federal Land Policy and Management Act (FLPMA) in 1976—for specific reclamation requirements to be implemented once mining operations ceased. The Surface Mining Control and Reclamation Act (SMCRA) of 1977 was then federally enacted by the Carter administration to counter the environmental effects of coal strip mining. SMCRA additionally administers abandoned mines on federal lands and requires all active mining operations to post a bond to ensure that adequate funds are set aside for reclamation purposes. Two years before SMCRA, the California state legislature enacted The Surface Mining and Reclamation Act (SMARA) of 1975, “to address the need for a continuing supply of mineral resources, and to prevent or minimize the negative impacts of surface mining to public health, property and the environment.”

In 2003, the California State Mining and Geology Board adopted regulations requiring the backfilling of open pit metallic mines within the state “to a condition that approximates the natural condition of the surrounding land and topography.”[16] Although most large open pit metallic mines are not required to fully backfill the excavated pit upon closure they must recontour the pit’s slopes to lessen the steepness of the grade. Spent heap leach pads, overburden and waste piles, sometimes miles in length, must be graded and revegetated. All mine buildings, mills and other structures must be dismantled and torn down.

The EPA lists industrial metallic mining as the largest toxic polluter in the nation. Consequently, many former mining sites require costly, and mostly continuous, environmental, health and/or safety remediation. Closure or reclamation bonds have been mandatory for mineral mining operations in the U.S. since 1977 in an effort to guarantee that former mining sites will be properly remediated and reclaimed once operations cease. It is important to note that a number of mining companies have been shown to be inadequately financed due to the fact that they are “self-bonded.” Once bankrupt, these same mining operations abandon the site leaving future cleanup costs in the hands of the taxpayer—illustrating how current financial assurance of reclamation bonds fails to cover the true, long-term cost of reclamation.

Responding to the failed self-bonding practice, the Obama administration later mandated that the Environmental Protection Agency (EPA) force hardrock mining operations to secure separate sources for mine clean up funding. The Trump administration, who is unraveling years of hard-won environmental regulation at many federal agencies, reversed this decision in late 2017. The reversal is being contested in court as it violates the 1980 law that spawned the Superfund program. Further, the Trump administration has very enthusiastically reopened 1.3 million acres (more than 2,000 square miles) of mining claims within the California deserts during 2018 that had been previously made off limits for extractive industry use by the Obama administration.

All in all, open pit, industrial-scale metallic extraction processes—especially those involving the cyanide heap leach method—are extremely problematic on a multitude of levels so a detailed overview of its history and process is warranted.

Cyanidation is a hydrometallurgical leaching method where aqueous cyanide is used to dissolve and extract microscopic gold and other precious metals from lower grade ores. As early as 1783, chemists knew that aqueous cyanide solution could dissolve gold, however, it took nearly one hundred years for the technique to be refined and utilized at large-scale gold extraction operations. [17] In 1887, Scottish mining chemists developed the MacArthur-Forrest cyanide process, which was first implemented successfully at South Africa’s Witwatersrand mining district in 1890. The Mercur Mine in Utah was the first American outfit to make use of the process during the following year. By suspending crushed ore in aqueous cyanide solution, up to 96 percent pure gold could be recovered. Cyanidation would revolutionize and replace the mercury amalgamation process at larger mining operations by the 1920s. Today, the process is used in 90 percent of all gold production worldwide.

Although cyanide is highly toxic and capable of causing immediate death in a variety of forms, it is relatively cheap and readily available for industrial purposes. Cyanide, for the most part, is biodegradable; exposing cyanide to sunlight, oxidizing it with bleach or hydrogen peroxide and allowing microbial processes to convert it into ammonia are ways cyanide is neutralized or broken down.[18] Although cyanide is manufactured primarily for industrial mining purposes, it also occurs naturally. A variety of plants and organisms, including some insects, along with certain bacteria, fungi and a surprising number of common vegetables, such as cassava root, along with seeds and pits from a variety of stone fruits, contain a form of the chemical.

The mining industry was once again transformed through an updated variation of the cyanidation process during the 1970s with wide-spread implementation of industrial-scale, open pit cyanide “heap leaching”—which allows lower-grade gold ores, containing as little as .02 ounces, to be mined profitably. Because conventionally mined, high-grade ore bodies were largely exhausted, mining industry enthusiasts welcomed the technology when the U.S. Bureau of Mines [19] began promoting the cost-effective technique in 1969. Detractors of the cyanide heap leach method have compared it to “dirt mining.”

Indeed, cyanide heap leach operations require massive earth moving, along with the energy to do so, plus billons of gallons of groundwater for processing ore. At some Nevada heap leach operations, whose production equals three quarters of all gold mined within the United States, up to one hundred tons or more of material is unearthed to yield a single ounce of gold.[20] Earthworks, a mining watchdog group, estimates that the production of one gold wedding ring today generates at least twenty tons of mine waste along with thirteen pounds of toxic emissions containing lead, arsenic, cyanide and mercury.[21] The Environmental Protection Agency (EPA) ranks the industrial-scale metallic mining as the nation’s top polluter of chemical compounds released into the environment.[22]

The process is designed as a closed loop system where highly alkaline aqueous sodium cyanide solution is dripped or sprayed onto industrial plastic-lined concrete pads laden with massive mountains of ore.[23] Once applied, the oxygenated “lixiviant” or leaching solution percolates through the heap, binding with the gold, eventually collecting into underground piping leading to the “preg pond,” which, as its name implies, is “pregnant” with microscopic gold. The process takes several weeks to months to complete—depending on the grain size of the ore and the height of the pad.

This concentrated gold-bearing cyanide liquor is then pumped into the recovery plant where giant vertical tanks containing very fine activated carbon that my friend, Tom O’Donnell, former metallurgist at the Rand Mining Company (RMC)[24] and long-time Randsburg, California resident, gleefully states, “the gold loves.” Attracted to the carbon, the gold abandons the cyanide to wait for further processing. The now-barren cyanide solution is replenished and re-circulated onto the leach pad. If, during the process, the massive mountain of ore somehow collapses—the entire operation is halted so the heap can be bulldozed back onto the pad. The ongoing threat of cyanide escaping this closed loop system is never taken lightly; “You never, ever, let that stuff get off that pad. You got people there 24 hours a day and that is their job to keep that cyanide inside the fence,” O’Donnell states.

After filtering this gold-bearing carbon concoction, caustic soda is added, dissolved and heated, which in turn, releases the gold from the carbon to produce a highly-concentrated gold-bearing solution. This mixture is pumped into a “cell” with positive and negative termination where it undergoes the electrowinning process first developed in 1807. A strong electrical current causes the gold to collect in the cell’s negatively-charged steel wool that is later recovered by melting the wool with flux in the furnace at around 2,100˚ Fahrenheit. Eventually, the iron rises to the surface and the heavier gold sinks to the bottom. The iron and flux is discarded leaving the remaining gold to be poured and molded into gold doré buttons ready for further refinement.

Magical, yes, but when all is said and done, a number of the world’s biggest cyanide heap leach operations have failed miserably over time. To date, the largest cyanide-related catastrophe in the U.S. occurred at the Summitville Mine in southwestern Colorado. In 1992, after leaching around ten million tons of gold and silver ore over a five-year period, resulting in 160 million gallons of cyanide-laced water, Canadian-based Galactic Resources Ltd. filed for bankruptcy and abandoned the site.

Soon it was disclosed that nearly 85,000 gallons of cyanide-contaminated waste along with acid mine drain containing heavy metals had leaked in the neighboring watershed including the nearby Alamosa River completely killing off all fish and other riparian wildlife over seventeen-mile stretch of the river.[25] The mine became a Superfund site in 1994, eventually requiring $250 million of federal funding for remediation plus an ongoing $2 million per year bill that Colorado taxpayers will need to continuously pay for many years to come. The Summitville Mine’s owner, Robert Friedland, who holds dual citizenship in both Canada and the U.S, ended up paying only $20 million out of pocket for remediation work of the Alamosa River but took in an estimated gross income of $150 million from the mine while it was operational.[26]

The Zortman-Landusky mines, bordering the Fort Belknap homeland of the Assiniboine (Nakoda) and Gros Ventre (Aaniiih) Nations in the Little Rocky Mountains of north central Montana, provides another example. One of the first heap leach operations in the county, the Zortman-Landusky had numerous cyanide spills while operational with the largest single incident involving 50,000 gallons.[27] Over time, related surface and groundwater pollution has resulted from their gold and silver mining activities in the form of extensive acid mine drainage plus arsenic, lead and other heavy metal contamination. The mines’ owner, Canadian-based Pegasus Gold Corp., began mining operations in 1979. Nineteen years later they went bankrupt and walked away from this ongoing water pollution disaster that has to date cost $100 million along with an additional $2 million a year paid by the state of Montana to contain the contaminated wastewater. Even though Pegasus set aside bond monies for such disasters, as required by law, taxpayers have taken up the bulk of the reclamation costs with the total clean up estimated to be in the tens of millions of dollars.

Understandably, a Montana citizen’s initiative banned cyanide heap leach operations in 1998. Wisconsin followed in 2001. Since that time other disastrous spills have occurred in North America include the 2014 Mount Polley Mine tailings pond dam breach at Imperial Metals in British Columbia and the Colorado’s 2015 Gold King Mine acid mine drain spill where the Environmental Protection Agency (EPA) and subcontracted workers charged with cleaning up the abandoned mine ended up accidentally releasing toxic water into the Animas River watershed. Cyanide heap leach operations continue to operate in California and Nevada—even though the EPA states that mining interests have polluted streams in 40 percent of the West’s watersheds.[28] In 2017 alone, metallic-bearing mines generated nearly two billion pounds of toxic waste—equaling half the amount produced by all industries combined nationwide.[29]

Nevada, the nation’s largest producer of gold, currently allows new mines to begin operations with full disclosure that they will pollute the surrounding watershed—possibly in perpetuity—which could require indefinite remediation to clean up contaminated groundwater, streams and pit lakes. The 2019 Udall/Grijalva bill, if passed, would ban this practice.[30]

Jim Kuipers, a hardrock mining engineer consultant, stated in a 2003 Mineral Policy Center report that taxpayers are likely to foot $1 to $12 billion in projected clean up costs at hardrock metallic mining sites across the country due to lax regulation and inadequate financial assurance upon mine closure or abandonment. The EPA says this figure is higher—$35 billion or more to remediate abandoned mines found across thirty-two states.[31]

But this story is more complicated than it appears at first glance. Tom O’Donnell, a.k.a. “Ordinary Tom,” defends the process, having overseen the cyanide heap operation at RMC from 1989 to 1994. RMC’s 2,520 acres of public and private holdings included the historic Baltic, Lamont and Yellow Aster mine, whose original “glory hole” was subsumed by RMC’s heap leach operation. During active production, RMC, on average, processed 45,000 tons of material ultimately recovering one million ounces of gold over the eleven years the mine complex was operational.[32]

Tom, a kind, gracious, progressively-minded man, now in his mid-sixties, began his career path in the Air Force where he served in Vietnam as a Crash Rescue Firefighter. Having been honorably discharged from the military in 1968, Tom worked a variety of jobs throughout the western United States and Alaska, including a stint as a photojournalist stringer for the Seattle Post Intelligencer, a cook on a tugboat, a logger and long hauler. After delivering a load to a mine in New Mexico, he was hired on the spot as a hardrock miner, which led him back to Alaska until he returned to New Mexico, eventually enrolling at Socorro’s New Mexico Tech chemistry program. After graduation he worked at a number of western mining operations, including RMC, plus a later stint at Panamint Valley’s Briggs Gold Mine located near Ballarat, California. But by his late thirties he had already determined that he could physically toil underground for just so long so overseeing heavy equipment operators, massive earthmovers and construction crews required for this new type of “mining” operation at RMC served him well.

O’Donnell is fascinated by the alchemy of the cyanidation process stating that “we don’t know exactly how the gold complexes with cyanide, or, for that matter, why it releases into the carbon.” When asked about the downside of the cyanide heap leach process, including its poor environmental report card, he’ll defend his work at RMC stressing, “who lives closest to the mines—the miners!” Although our opinions differ about the merits of cyanide heap leach technology and mining microscopic gold and other profitable metals at such a massive scale, I respect Tom immensely as he is open to debate and willing to consider multiple sides of this contentious issue. Tom, reflective of many other men and women like him, are proud of their careers in the mining industry, which provides much needed skilled and higher-than-average paying jobs in many rural regions of the West. His friendship provides an insider’s look into an industry that I would not have encountered in my day-to-day life if I had not embarked on a project looking closely at the culture and geology of the Mojave Desert.

Large-scale, industrial mining in Randsburg faded out during the early 2000s when RMC shuttered operations leaving off-roading and related tourism as the primary economic force driving the community. The BLM continues to manage the Rand Mining District’s public lands, including the plethora of abandoned mines surrounding the town.

It should be mentioned too that RMC, like many other industrial operations of similar scale, had its share of accidents and wildlife fatalities, but no single incident was exceptionally newsworthy.[33] This is perhaps due to the fact that catastrophic surface stream and watershed contamination is less of an issue in the Mojave Desert due to the absence of such pronounced aquatic features near most of the region’s desert mining sites.[34] Still, these former mining operations present other serious environmental challenges including ground, airborne and groundwater contamination.

In early 2006, it was determined by the Department of the Interior (DOI) that the Rand Mining District (RMD) had severe levels of arsenic contamination measuring 4,700 times higher than what the EPA considers acceptably safe, triggering a rarely-enforced DOI Flash Report.[35] Arsenic is a common, naturally occurring element. Generally, it is a significant component of gold deposits found within the western United States. In areas that have been extensively mined arsenic levels are often elevated, which can lead to environmental contamination.

This well-known poison can be toxic and can cause mortality to both humans and wildlife. Mining processes unearth and concentrate arsenic in spent mine tailings and waste ponds, which sometimes leads to groundwater contamination. The 2007 DOI report identified “arsenic contamination in over 3,000 acres of mine tailings and 500,000 tons of additional mining related waste rock” within the RMD estimating the cost to cleanup at $170 million—at the time considered to be the largest BLM remediation project in its history.[36] Responding to the DOI report the BLM initiated their Abandoned Mine Lands (AML) program in 2009 to deal with the issue.

In addition to arsenic contamination, high levels of toxic mercury, lead and other heavy metals were also measured throughout the site but airborne arsenic hazard carried by dry desert winds and exacerbated by recreational off-road use is still the main health concern. The 2007 DOI report listed as many as 30,000 visitors utilizing the area on holiday weekends. For many years, off-roaders drove on the popular Route 110 trail leading across a sixty-acre arsenic-contaminated former mill site before it was closed in 2007 due to its potential to expose riders to toxic dust. Off-highway vehicle (OHV) trails on desert public lands within the surrounding area were posted with warning signs and/or cordoned off thus limiting recreational access.

Because Randsburg is economically dependent on OHV recreation and related tourism the closures proved controversial for business owners and many local residents. After BLM oversaw mitigation work at the mill site that included fencing off and capping the arsenic hazard with an earthen berm, rerouting Route 110 alongside the fence line and posting arsenic warning signs, the trail was reopened to riders. When asked about the arsenic contamination O’Donnell casually brushes the issue aside commenting, “Well, no one in town has died from arsenic as far as I know and we’ve have had our share of old timers that have lived to nearly one hundred.”

In 1984 and 1997, the BLM allowed the Randsburg and other area residents to purchase titles to their properties but only if buyers agreed to indemnify or hold harmless the federal government in regards to exposure to hazardous materials from mining activities. BLM supervisors had known about the district’s arsenic contamination for decades but failed to officially test and assess how widespread and serious the hazard actually was. A 2008 DOI audit report additionally criticized the agency for its marginalization of the arsenic contamination issue along with its neglect to identify and secure physical hazards at the many abandoned mines found across the public lands they manage. Indeed, the report stated that some BLM employees had even received threats after identifying grossly contaminated or unsafe former mining sites because their supervisors worried, that in some cases, by identifying the hazard the agency would be more susceptible to lawsuits.[37]

True, these physical safety hazards are not exaggerated. Every year, curious explorers of abandoned mines, both seasoned and amateur, along with a number of unwary victims are seriously injured or even die after knowingly or unknowingly entering one of these many dark, subterranean spaces. Accidents include falling or driving vehicles into shafts, encountering poisonous gasses or no air at all deep inside tunnels, drowning in flooded chasms, being crushed when aging mine support structures fail or even being blown to bits by long forgotten stashes of dynamite.

Forty plus accidental deaths have been documented in abandoned California desert mines since the mid-1970s. In separate incidents, three people accidentally fell to their death upon entering the “ant trap” funnel mine shaft of the Goat Basin Mine bordering the eastern edge of Joshua Tree National Park. Several deaths have occurred in the Rand Mining District, including that of twenty-one year-old Matthew Frey who would plunge to his demise in November 2004 after riding his motorcycle up a moderate incline and falling into a 700-foot-abyss in the neighboring Spangler Hills OHV area.

Two years before Frey’s death, a fourteen-year old boy would be luckier—this dirt bike rider would tumble into a nearby 780-foot shaft but was saved after landing on a support beam some 200-feet below. Sterling White, who administers the BLM’s California AML program commented that Randsburg’s Baltic Mine area alone had 300 holes to his agency had to contend with. In 2019, they will oversee sixty mining-related “features” requiring securing in the Red Mountain area. Indeed, out of the thousands of identified abandoned mining sites, each has up to a dozen hazardous mining-related features that require mitigation. Millions of dollars have been spent so far in an ongoing effort to do so.

Other OHV-related fatalities resulting from falling into abandoned mines would occur in the Calico Hills OHV area and other areas of the Mojave Desert. In 2007, a young girl died when she and her sister accidently drove their all-terrain vehicle into a 125-foot mineshaft while riding in the Windy Point Recreation area outside of Kingman, Arizona. Unsuspecting tourists have nearly backed into holes large enough to swallow entire vehicles. A rancher on horseback survived a fall into a collapsed horizontal shaft or adit. Dogs have been successfully rescued, but certainly this has not been case for the multitude of livestock and wildlife that have unwittingly plunged to their deaths. Sadly, dead bodies are sporadically found dumped in mineshafts as well. The BLM, NPS, private landowners and even recreational off-roading clubs such as the Havasu 4 Wheelers have secured some of the most egregious hazards, often using steel bat gates, but many remain humanly accessible—sometimes because fences or warning signs are illegally removed. Still, the BLM discourages community involvement because anyone or group doing so then becomes legally liable for any accident or death that may occur after the modification.

Abandoned underground mines have found reuse as Cold War-era bomb shelters, and more creatively, as a community-led time capsule project. Various municipal civil defense entities have in the past outfitted subterranean spaces for nuclear fall-out shelters—some equipped with enough supplies to support 17,000 survivors, provide decontamination plus a water supply. Such was the case of U.S. Borax’s tunnel shelter constructed within the old Suckow colemanite mine now part of the open pit Rio Tinto Mine in Boron, California.[38] Victorville provided a similar service for 200 individuals at the nearby Apex Mine. The Sidewinder Mine, located between Victorville and Barstow, could host 859 people in the event of a nuclear war providing them with 200-bed hospital, a library and exercise room in exchange for materials, cash and/or labor to secure their spot. A seed bank was also housed here.

Rosamond, California’s 300-foot long Tropico Time Tunnel, housed in a former gold mine [39] of the same name donated for the purpose, was sealed with concrete on November 20, 1966 containing a brand new Yamaha motorcycle, a baseball autographed by Willie Mays, a model of the XB-70 bomber, a typewriter, twelve copies of the Antelope Valley Press, a packed suit case, a female mannequin and a local’s favorite fishing shirt among many other mundane domestic and everyday objects donated for the purpose by local residents. The time capsule was the brainchild of Jack Tomlinson, a San Francisco State University biology professor. The public mine sealing event coincided with Kern County’s centennial with the “unsealing” of the capsule scheduled for the county’s 1000th birthday in 2866.[40]

Just a few miles north of the Tropico Mine is the only industrial cyanide heap leach operation currently active in the Mojave Desert. The Canadian-owned Golden Queen Mine LLC in Mojave, California runs 24/7 on Soledad Mountain, located just west of State Route 14. Gold was originally discovered here in 1894. Along with the Randburg’s Yellow Aster, these two mines produced half of all gold mined in Kern County. Several of Soledad Mountain’s mines were consolidated into the Golden Queen Mining Company in 1935 which operated until 1942 when Limitation Order L-208 was enacted effectively outlawing mining of non-strategic metals such as gold and silver during wartime. The majority of the Mojave District gold and silver mines have remained inactive after WWII ended.

The company that currently runs Golden Queen purchased it during the mid-1980s but did not commence operations until 2016. As of July 2019, Golden Queen LLC’s stock was listed at $0.0155 per share. Their website published a one-month loan payment extension in the amount of $75,000 posted on January 31st, 2019.

Further west, on the southwestern slope of the Panamint Range near Ballarat in Inyo County, lies the inactive Briggs Gold Mine named after Harry Briggs who operated a mill and cyanide plant below nearby Manly Falls during the 1930s. CR Briggs Corporation began their open pit heap leach operation in 1996, producing 550,000 ounces of gold until they shuttered operations in 2004.[41] CR Briggs was invariably a highly controversial mining operation due to its proximity to Death Valley National Park, which is a mere stones throw away. When gold prices rose in 2009, Atna Resources LTD reopened the mine but went bankrupt by 2015. DV Natural Resources, LLC, a Virginia-based company currently owns the mine. Renewed attacks on the 2016 Desert Renewable Energy Conservation Plan (DRECP) by the Trump administration that have previously protected Panamint Valley from further industrial mining activities may allow Briggs to resume operations along with a separately proposed lithium mine on the valley floor.

East of Briggs and about one hundred miles west of Las Vegas, the Castle Mountains rise out of northern Lanfair Valley. The Hart Mining District had previously sprung to life here in 1907 after gold had been discovered. Hart faded out by 1915 but seventy-five years later Viceroy Gold Corporation would resume mining operations via cyanide heap leach until they, too, closed in 2001. NewCastle Gold Ltd. would purchase the 1,375-acre site in 2012 and resell it in October 2017 to Vancouver-based Trek Mining Inc., soon after renamed Equinox Gold.[42]

A year before the sale, President Obama had signed an act designating a remote 20,920-acre parcel surrounding the site as the Castle Mountain National Monument—just before he left office in January 2016. His effort would fill a missing piece of the Mojave National Preserve that borders the mine on three sides. Obama’s designation was celebrated as a suitable compromise for both the mining industry and environmentalists but with one hitch—the deal included an option to continue mining though 2026.

Behind closed doors it is apparent that NewCastle was not entirely happy with the Obama administration’s earlier deal. By mid-2017, if only by coincidence, Representative Paul Cook (R-Yucca Valley) demanded that former Interior Secretary Ryan Zinke reduce the monument by 50 percent. It should be noted that NewCastle was in the process of selling the mine to Trek/Equinox during Cook’s request. More revealing is the urgency to suddenly reopen the mine—apparently driven by language within the monument designation stating that if no mining resumes within ten years of the act’s signing then the holdings would be transferred to the National Park Service thus becoming part of the larger Mojave National Preserve. Cook’s boundary adjustment request continues to be under consideration by Zinke’s replacement David Bernhardt. If realized, the mine’s activities will create ongoing vehicular traffic, noise disturbances, possible pollution along with excessive groundwater depletion that will most likely impact the sensitive Piute Spring, the only perennial stream in the area.

Equinox Gold completed their pre-feasibility study in July 2018. Construction of the heap leach pad and commissioning of the processing plant is expected for late-2019. Their website states, “The Castle Mountain heap leach gold mine in California produced more than one million ounces of gold from 1992 to 2004. Equinox Gold intends to put the mine back into production with the expectation of producing 2.8 million ounces of gold and generating US$865 million in after-tax cash flow over a sixteen-year mine site.”[43] To do so, Equinox will need to re-excavate fifty-one million tons of material that was previously dug out and used to fill the pit it had created during the process. It appears that looser federal mining regulations bought on by the Trump administration are the incentive to begin gold mining here and in other areas of the Mojave.

Perhaps most disturbing is an ongoing proposal for an open pit cyanide heap leach operation within the Inyo Mountains’ remote Conglomerate Mesa, located west of Death Valley National Park. The mesa lies directly south of Cerro Gordo Peak and just north of the Malpais Mesa Wilderness. Unlike the heap leach mining operations at Soledad and Castle mountains or even Randsburg, where extensive mineral extraction had previously occurred, Conglomerate Mesa has never been historically mined although the area was used to primitively produce charcoal for the nearby Cerro Gordo Mines. The mesa is an important indigenous site for local tribes having served historically as a seasonal piñon seed harvesting area. Since 1984, no less than ten mining companies have tested for gold at this rugged, roadless 7,000-acre site and left, dissatisfied with their findings.

The latest outfit to do so is Vancouver-based Silver Standard Resources (now SSR Mining Inc.), owner of Nevada’s Marigold Mine, an enormous Carlin-type heap leach operation located in northwestern Nevada. SSR obtained permits in May 2018 from the BLM for seven 1,000-foot exploratory test-drilling sites to be accessed entirely by helicopter for their speculative “Perdito Exploratory Project.” SSR’s exploration activities would have necessitated up to 1,000 gallons of water per day requiring a hose line to be laid from an existing road to the drilling site, 24/7 illumination of the work area to allow for continuous construction and drilling plus multiple daily helicopter flights to transport crew members, drilling rig, generator, outhouse and other necessary equipment—in a setting devoid of human activity other than an occasional jet flying miles overhead.[44]

Conglomerate Mesa is designated California Desert National Conservation Lands under the 2016 Desert Renewable Energy Conservation Plan (DRECP) with an Area of Critical Environmental Concern (ACEC) requiring “special management attention” by the BLM. Previous test drilling at the Perdito site yielded unsatisfactory results. Not surprisingly, under mounting opposition from public and environmental groups, SSR withdrew its application by mid-summer. However, the actual claimholders, partners Steven J. Van Ert and Noel Cousins, both of Chatsworth, California, who have 444 twenty-acre active mineral lode claims between them, on or near the mesa, covering 8,800 acres, were given the option to transfer the drilling authorization to themselves.[45] This provides Van Ert and Cousins with an opportunity to “indefinitely pitch the project to other mining companies, leaving the future of Conglomerate Mesa in limbo.”[46]

Keep in mind that the annual maintenance fee for each of these Conglomerate Mesa area claims is $155 so the duo must pay a total of $68,820 in federal fees a year just to retain their active status.[47] According to a December 2017 article by Tom Budlong in Desert Report if they had been successful in securing SSR to test drill here, Van Ert and Cousins would have collected $710,000 for a three-year lease option and several million more once production began, according to SEC documents filed on March 22, 2016.[48]

Friends of the Inyo and several other environmental groups filed for the BLM to conduct a formal review by the state director of the project in November 2018 expecting to hear a decision within three months but the winter 2019 government shutdown delayed it until May when it was announced that the “Perdito Project will stand and exploratory drilling can move forward.”[49] If Van Ert and Cousins enlist some new company to explore and mine at Conglomerate Mesa, a bleak and discouraging precedent in wildlands protections will be set allowing multinational extraction corporations to swoop into California and other western states and set up industrial-scale heap leach operations wherever they see fit.

Biologists stress, too, that keeping Conglomerate Mesa remote and undeveloped is critical for the endemic Inyo Rocky Daisy (Perityle inyoensis) that is classified a BLM-sensitive species and also for the Joshua tree (Yucca brevifolia) in that as the species begins its retreat due to climate change from lower elevations, including Joshua Tree National Park, to higher areas at 3,800 to 7,700 feet, wilderness areas such as the mesa will afford a haven for the retreating species and provide a crucial habitat for its ongoing survival.

Over the state line in Nevada, the Bullfrog/Beatty Mining Districts remain the only active large-scale gold mining areas within the state’s eastern Mojave Desert. Nevada is the nation’s top gold producer with the majority of the state’s active open-pit industrial-scale gold mines located in its northwestern Great Basin interior where massive Carlin-type gold reserves are geologically situated.

At the start of 2019, the Pahrump Valley News reported that Beatty was undergoing a gold mining renaissance—two major international gold extraction corporations were conducting exploratory drilling, including South Africa-based AngloGold Ashanti, noted to be the third largest gold producer in the world. Several smaller players, including a couple of U.S. based mining companies, were also conducting feasibility testing and research.

The Sterling Gold Mine, located fourteen miles southeast of Beatty, California, was operated between 2007 and 2011 by Vancouver B.C.-based, Imperial Metals—the same outfit responsible for the August 2014 Mount Polly mine tailings breach. Canadian-based Northern Empire Resources, Corp. purchased Sterling from Imperial Metals for $10 million in May 2017, flipping the property a year and half later when major player Coeur Mining Inc. acquired Sterling in August 2018 for $90 million—a transaction reflecting the dizzying world of speculative international metallic mine trading.

It is interesting to note the Pahrump Valley News reported in March 2014 that Northern Empire’s mining activities had forced the Nevada Depart of Wildlife to relocate “herds” of bighorn sheep from the active mining area—operational for a mere four years. Sterling’s general manager Chuck Stevens was quoted in the article stating, “Because the herd is so large they’re flying them out of here and shipping them out of state. They net them on the mountain range, fly them down, then we give them a physical exam, measure them, weigh them, put them in a trailer and haul them to wherever they’re going to relocate them.”[50]

In Arizona’s northwestern Mojave Desert, known for its own rich history of nineteenth century gold mining, the historic 1902 Gold Road Mine at Oatman, Arizona, was operated as a cyanide heap leach from 1995 until 1998 and then reopened from 2010 to 2016. Columbia-based Para Resources Inc. which “specializes in low-risk, low-cost gold projects in North and South America that have strong development potential”[51] purchased this fully-permitted modestly-sized mine for $7 million in August 2017 and began underground mining operations in late 2018.

Mining will always be a crucial part of our nation’s economy. While many materials, chemicals and products used in everyday life are derived from rich mineral resources extracted within the Mojave Desert, gold, mainly mined worldwide for economic gain and adornment, serves no real benefit for humankind—other than the continued exploitation of publicly-held mineral resources that provide enormous profits for a handful of mostly foreign-based multinational enterprises and their investors.[52] Gold should be the first metallic mineral in line to be levied with a substantial, but sensible, royalty when commercially extracted. Regulators must additionally require independent and comprehensive closure bonds that cover the true costs of long term environmental remediation after production ceases. And last, tighter environmental regulations are needed to reign in this unbridled industry that has for over 150 years been a Congressionally favored recipient of the last remaining federal land giveaway plus many other generous federal and state subsidized tax breaks and perks.

Tom O’Donnell, and other pro-mining advocates like him, argue that industrial gold mining operations require owners to assume huge upfront financial risks just to begin operations and are lucky if they manage to make a 5 percent profit on their gross income. He stresses that for every dollar a mining company spends internally the amount is multiplied and dispersed seven fold within the local economy. Those statements may be true, but if the massive infrastructure, energy and human power funneled into the world’s gold mining endeavors are, in turn, channeled to sustainably mine the materials required during our transition towards a non-fossil fuel-based clean energy future then there should be more than enough jobs for miners along with sustained regional economic development within the Mojave Desert and Great Basin for years to come.
