Mines of El Dorado County: “D”

A lode gold mine known as the Dailey and Bishop was located two miles south of Grizzly Flat. It was active around 1896 when a one and one-half to three-foot vein of gold bearing quartz in slate was developed by a 800-foot drift adit, crosscuts, and winze. The ore was treated on site in a ten-stamp mill.

Just east of the town of Kelsey was the Dalmatia (Kelly) Mine, a large lode gold mine. Numerous quartz seams and a quartz vein were found in a zone that varied in width from 20 to 50-feet, which were worked in the 1880’s, 1890-94 and again around 1935. A two-foot vein assayed at $16 per ton, a single pocket yielded $14,000 and the seams yielded around $2 to #3 per ton. The mine was originally worked in an open cut some 500 feet long and later was developed by a 200-foot inclined shaft and a 1200-foot adit. The ore was treated on site in a 10-stamp mill.

The Daniel McGee claim was 30 acres on the north side of the South Fork of the American River, just northwest of Lotus.

The Daniel R. Carson claim was on the North Fork of the Cosumnes River in Ladies Valley, about one and one-half miles downstream from Bucks Bar. It was 120 acres in size.

The Daniel T. Hall claim consisted of 50 acres on White Oak Creek, about two miles north of Shingle Springs

The Darling (Chanced Upon) mine was four miles northeast of Spanish Flat. A two-foot vein of gold bearing quartz in slate yielded $5 to $6 per ton in free gold. The deposit was developed by a 190-foot shaft. The ore was treated on site in a 10-stamp mill.

The Darlington mine was a soapstone mine three mines southeast of Placerville, near Weber Creek. It was active in the 1880’s when sawed slabs of soapstone were produced. The massive lens up to 25-feet wide and 130-feet long was developed by open cuts.

The Darrington (Gurney) mine was a chromite mine located seven miles southwest of Pilot Hill. Worked originally during WWI, when several hundred tons of ore were produced, it was reopened during WWII and worked in conjunction with the nearby Dobbas Mine. During this later period of operation, some 495 long tons (2240 pounds in a long ton) were removed, mostly from the Darrington workings. The ore is in two zones of disseminated chromite with a high iron content. The east ore zone is about 300 feet long and 70 feet wide, and estimated to contain some 100,000 tons of ore. The west zone has not be significantly worked. Development has been by open cuts, four adits totaling 900 feet and shafts and raises totalling 120 feet.

On the Mother Lode, one-half mile east of Garden Valley was the Davenport mine. A lode gold mine, it was originally active in 1934 and later worked jointly with the Black Oak mine. It was developed by a 280-foot crosscut adit and open cuts.

The Davey Quartz mine was on the Mother Lode, on the south side of Placerville.

The David mine was a manganese mine just to the west of Georgetown. Open cuts were used to remove the ore that averaged from five to ten percent manganese.

The David W. Cary placer mine was located one and one-half miles north of Georgetown and consisted of nearly 160 acres. It was so large it was in two different townships.

The Davison mine was a lode gold mine located two miles northwest of the townsite of El Dorado. Originally worked sometime prior to 1894, it was later owned by Jerome M. Strickland and was often referred to as the Strickland Mine, from which Strickland Mine Road gets its name. A two-foot vein of gold bearing quartz was developed by a 280-foot inclined shaft with 100 and 300-foot levels. The ore was treated in a 20-stamp mill, which was later replaced with a smaller, 5-stamp mill.

The Day and Taylor quartz mine was on 20 acres one and one-half miles north of Grizzly Flat.

The Deadhead placer mine consisted of 200 acres on a tributary of Clear Creek, about one mile northwest of Pleasant Valley.

The Deep Channel placer mine consisted of 100 acres one-half mile northwest of Indian Diggings.

The Defiance mine was a very small lode gold mine five miles northeast of Shingle Springs. Nothing much more is known about it. There was also a Defiance placer mine on 160 acres just west of Garden Valley.

The Del Ray mine was a lode mine just north of the South Fork of the American River, three miles southeast of Pilot Hill.

The Demuth mine was a lode gold mine on the Mother Lode one mile south of Garden Valley.

The Detert mine was a copper mine about one-half mile east of Pilot Hill.

The Diamond Hill placer mine was a part of a large ancient (Tertiary) gravel area to the north of the townsite of Diamond Springs, remnants of which can still be seen in open cuts along Highway 49 near Lime Kiln Road. Much of it was mined hydraulically, many years ago before mining by this method was outlawed by the State of California in response to siltation complaints from the agricultural interests in the valley, among other reasons.

The Diamond Springs Limestone mine is a large limestone quarry three miles to the east of Diamond Springs, on Quarry Road. Limestone has been mined at this location since at least the days of the Gold Rush, and probably even earlier. Within the structure of the Washington Monument, in Washington D.C. the Great State of California is represented by a block of limestone donated from this quarry over a hundred years ago.
When this limestone lens, some 2,500 feet long and as much as 500 feet wide was owned by the Diamond Springs Lime Company, the material was mined and shipped to their processing plant just north of the townsite (now the location of the refuse transfer station) by a unique (and unquestionably noisy) overhead tramway. The three mile long aerial tramway had 149 buckets of 800 pounds capacity each, that could supply the plant with as much as 30 tons per hour. Where the tramway passed over roads, the roads and vehicles were protected from falling rock by a steel mesh cover. The tramway was disassembled around 1954.
With the tramway gone, the Diamond Springs Lime Plant started getting most of its material from mines in Shingle Springs and Cool. When the federal government purchased the part of the mine in Cool from which their material came, the lime plant was unable to find another suitable source and closed.
The mine on Quarry Road, which is developed by a large open pit, continues to operate, providing high grade limestone for the road building, agriculture, and pharmaceutical industries, among others.

The Dick Canon (canyon in Spanish)  Placer mine was located on 20 acres, about one mile south of Omo Ranch.

Three miles east of Clarksville was a chromite mine known as the Dickson mine. Here, ore was mined from a northwest-trending series of chromite pods by using an open cut.

The Dirty Flat mine was a placer mine about one mile east of Smith Flat.

The Dividend mine was on Pinchem Creek, some four miles northwest of Rescue. During the 1880’s, 1890’s and from 1912-15, an extensive deposit of gold bearing gravel one to three-feet thick on granite bedrock was worked by ground sluicing.

The Dobbas mine was located two miles north of Flagstaff Hill. During WWI, when the property was owned by the Placer Chrome Company and a portion leased to the Union Chrome Company, there was a substantial amount of work at this mine when a number of open pits, and several shafts and adits were developed. During WWII, the appropriately named Rustless Mining Company removed some ore from this property which, along with ore from other mines in the area (including the Darrington) was taken to the Volo Mill near Placerville where it was concentrated. The deposit consists of several ore bodies of talc-chlorite or talc-serpentine rock. Like the ore at the Darrington mine, it was also high in iron. Five principal ore bodies have been worked there by open pits and shallow shafts.

One-half mile east of Greenwood was the Donozo mine. At this location a small vein of gold bearing quartz was developed by 60-foot drift adits.

The Dormody Placer mine consisted of a series of claim totaling 166 acres on Green Springs Creek at Green Valley Road, about one and one-half miles north of Bass Lake Reservoir.

The Dorsey was a placer gold mine on 197 acres, one mile northeast of Indian Diggins on East Indian Creek.

The Drouillard Placer mine was near Indian Diggings. Nothing more seems to be known about it or any Mr. Drouillard.

The Double E mine was a manganese mine two miles southeast of the townsite of El Dorado. It was only a small, low-grade deposit and never significantly worked.

The Dr. Wren mine was a copper mine located three miles southeast of El Dorado, to the east of the Mother Lode. A six-foot vein of ore, containing 5 – 18 percent copper was developed by a 18-foot shaft.

The Duncan and Adams mine was one mile southeast of the townsite of El Dorado. A lode gold mine, it was only active in 1931 when 700 tons of ore was mined that yielded $10,266.

The Dyer mine was a lode gold mine about two miles due west of Grizzly Flat.

Mines of El Dorado County: “E”

The Eagle mine was a lode gold mine located on 47 acres one and one-half miles north of Grizzly Flat. A three foot wide vein was worked for gold, while another deposit 150 feet long and up to 6 feet wide contained appreciable amounts of auriferous (gold containing) pyrite, galena (lead ore) and sphalerite (zinc ore). The mine was developed by a 780-foot drift adit and a 240-foot shaft.

A second Eagle lode gold mine was located on 18 acres just east of Greenwood.

A third  Eagle mine was a placer gold mine on 122 acres about one and one-half miles northwest of Omo Ranch on a tributary of the Middle Fork of the Cosumnes River.

The Eagle Bird mine was a placer mine three miles southeast of Placerville.

The Eagle King mine was a lode gold mine near the first Eagle Mine mentioned, one-half mine further north of Grizzly Flat. A gold bearing quartz vein three to four feet wide, like at the Eagle Mine, contained not only free gold but also appreciable amounts of auriferous pyrite, galena and sphalerite. The mine was active from 1894-1896 and developed by a 1200-foot drift adit and a 60-foot winze 200 feet from the portal. The ore was treated in a ten-stamp mill.

The Earl Quartz mine was a lode gold mine one mile west of Grizzly Flat.

The Earl Fruit Co. mine was a placer mine located near the South Fork of the American River and is now under Folsom Lake. The Earl Fruit Co. was a major fruit packing company with a large facility in Placerville at one time.

The Echo claim was on the Mother lode one and one-half miles northeast of Diamond Springs.

The Eden Consolidated Quartz mine was on 31 acres of the Mother Lode, one and one-half miles south of Placerville.

The Edner mine was located on 87 acres one and one-half miles southeast of Omo Ranch, in the very southern part of El Dorado County. A one and one-half foot wide vein of gold bearing quartz was mined in 1896 and developed by an 150-foot adit and a fifty foot shaft. There was also an Edner Placer mine near or at the same location. It is listed as being 87 acres in size.

The Edward Crocker claim was on 140 acres three miles west of Rescue. Given its location, it was probably a lode gold claim.

The E. E. Copper mine was four miles southeast of El Dorado. In addition to copper, gold and silver were mined at this location by means of an 85-foot vertical shaft, 200 feet of drifts and 100 and 300-foot adits.

There have been a number of mines in the county with the name El Dorado. The Church mine, two miles south of the town of El Dorado, was once known as the El Dorado. There was also an El Dorado lode gold mine in Spanish Dry Diggings, just south of the Middle Fork of the American River and and El Dorado placer gold claim on Otter Creek, six miles northeast of Georgetown.

The El Dorado Big Tunnel Company was a mining company that, in the 1890’s, operated a mine at Big Canyon, two miles north of Placerville. Later the mine was purchased by the Gentle Annie Mining Company. Ultimately, this mine, under the name of the Gentle Annie, would be consolidated with the Bell, Hall Consolidated, Lucky Star, Lyon and New Era claims under the name of the River Hill Group. The El Dorado Big Tunnel Company also operated a slate mine near Chili Bar around 1894.

One mile south of Garden Valley was the El Dorado (Roosevelt) Copper mine. Located on the Mother Lode gold belt, the mine was originally worked for gold in the 1860’s. During WWII some copper was discovered and mined. Because of the need for copper for the war effort, during the period 1944 – 45 the U.S. Bureau of Mines used a diamond drill to create eleven exploratory holes, aggregating a total of 1613 feet. Eight of these holes indicated the deposit to be a series of narrow, intermittent lenses of copper ore in an area about 600 feet in length and several hundred feet deep. The ore contained from five to more than ten percent copper, as much as one and one-half percent zinc, one ounce per ton of silver and traces of nickel and gold. The mine was developed by a 100-foot inclined shaft, a 173-foot adit, driven as a crosscut for forty-six feet and a drift for 127 feet, which connects with the shaft at the fifty foot level, 128 feet in from the adit portal. On the 100 foot level, there are drifts extending thirty-five feet to the north and ten feet to the south.

The El Dorado County Road Department (later Public Works and now Department of Transportation) has operated several stone quarries over the years. From these deposits of decomposed granite they have taken material for “road metal” (surfacing material), fill material and sand for increasing vehicle traction on icy roads. Presently they operate only one sand quarry on Sandridge Road, near the townsite of Somerset. But, at one time there were county operated sand and gravel pits in the Deer Valley-Rescue-Shingle Springs area, just south of Lotus and a few miles east of Mt. Aukum. Serpentine material was also excavated by the county for “road metal” from the Hummingbird Ranch quarry one mile west of Garden Valley.

The El Dorado Dredging Corporation was a mining group that operated a one and one-half cubic yard dragline dredge on Greenwood, Coloma, Rock Canyon, and Irish Creeks during the years 1940-42 and again in 1948.

The El Dorado Limestone mine was an underground operation, three miles southwest of Shingle Springs. From it was produced high-calcium (97 percent plus) limestone for various uses including the manufacture of lime, steel and glass, beet-sugar refining and construction materials. Prior to the opening of the mine by the El Dorado Lime and Minerals company in 1918, limestone was quarried just north of the mine and burned in nearby stone lime kilns for building purposes. In 1931, the El Dorado Limestone Company was formed and operated the mine until it closed. The deposit consists of two lenses of limestone, one averaging sixty feet in width, the other forty feet. The main working entry is a 1000 foot, three compartment vertical shaft near the east wall of the east lens. Crosscuts extend from the shaft to the west lens. The deepest workings were at the 800 foot level. Because the material is solid, no timbering is required. In the 1970’s mining ceased and the shaft was allowed to flood with water. The crushing equipment on the surface continued to be used for several years, the limestone coming from the Gallo Glass mining operations at Marble Valley, to the west.

The El Dorado Slate Products Company (Chadborne) operated a slate mine on the south side of Big Canyon (apparently there are several Big Canyons in El Dorado County), one and one-half miles north of Placerville. Roofing slate was produced from several quarries during the 1920’s, which was then sent across the canyon via an overhead cable. Waste was sold for roofing granules.

The Estelle was a lode mine consisting of 10 acres on the Mother Lode, two miles south of Kelsey.

The Ethel lode claim was six miles east of Garden Valley. Nothing else is known about it.

It is not surprising that there were at least six mines with the name of Eureka, it being the motto of the State of California. One of these became a part of the Woodside-Eureka mine, another a part of the immense workings of the Placerville Gold Mining Co. The Eureka mine just north of Georgetown was only active prior to 1888. Three parallel veins of gold bearing quartz, six to ten feet wide, were developed by a 240-foot inclined shaft and 500 feet of drifts. One Eureka lode mine was on 20 acres two miles west of the town of El Dorado while another was on 10 acres two miles west of Grizzly Flat.

Placer mines named Eureka were located on 37 acres one mile east of Kelsey, on 60 acres along the South Fork of the American River just north of Lotus and on a tributary of Weber Creek, one and one-half miles south of Placerville. This last one may have been the one controlled by the Placerville Gold Mining Co.

The Eureka Slate Quarry, operated by the Sierra Slate Company, was located one mile south of Kelsey. This was a big mining operation that was active for some forty years, from around 1886 until 1926. Dimension slate for a multitude of uses was mined from the quarry that had a 200-foot face and a depth of 200 feet. The mined slate was delivered to Placerville for transport on the railroad by means of a spectacular 13,000 foot long aerial tramway.

The Excelsior mine was adjacent to the Coon Hollow, one mile south of Placerville. Between the years 1852 and 1871, about five million dollars in gold was recovered by drifting and hydraulicking this ancient river channel, resulting in much of what is now known as Big Cut. Later, in the years 1907 – 11, the deposit was further worked by drifting. The gravel from the drifting operation was treated in a ten-stamp mill.

Three miles north of Shingle Springs was the Expansion, a lode gold mine. Here auriferous pyrite was the gold source. The deposit was worked form 1900-04 and later prospected in 1936. Mining was by way of a 150-foot crosscut adit.

The Extension of the Phillips and Joiner quartz mine consisted of nine acres two miles west of Grizzly Flat.

One of the largest seam gold mines in El Dorado County was a consolidation of the Bettie and Parsons Consolidated, Blue Rock, Mulvey Point and Pacific mining claims, known commonly as the Georgia Slide mine. It was located one and one-half miles north-northwest of Georgetown on the south side of Canyon Creek. Its name is derived from miners who came from the gold mines in the state of Georgia, near a town named Dahlonega, where gold had been discovered in 1828. It was these experienced Georgia miners who were some of the earliest in the gold fields of California and who brought with them, and shared with others, much of the needed mining knowledge and experience.
Originally the several claims making up the Georgia Slide mine were worked individually by hydraulicking from 1853 to 1895, using water from Canyon Creek, North Canyon and Dark Canyon. After the cessation of hydraulic mining, small amounts of ore were treated in several stamp mills on the property. In 1915 a 10-stamp mill was erected to rework the accumulated tailings. The total estimated output from the seam deposits is $3,000,000 and from the placer deposits in Oregon Canyon and Canyon Creek, which derive their gold from the seam deposits, another $3,500,000. It is estimated that 3,500,000 cubic yards of material was removed from the immense pit that still remains. The seams ranged from less than an inch to a foot or more in width, some swelling into lenses several feet thick. After hydraulic mining stopped, the banks were excavated by blasting and the debris was directed by water pressure into a sluice. Whenever quartz seams were encountered they were treated by hand mortaring. The pit is about 1000 feet long and about 600 feet wide at the top.

Three miles south of El Dorado on the Mother Lode was the German (Haeger or German Group) mine. Consisting of 11 acres, it was active around 1896 – 1900 and developed by a 500-foot inclined shaft. Ore was treated at the mine in a 10-stamp mill.

The Gibralter Group had a lode gold claim on the Mother Lode one-half mile southeast of Diamond Springs.

The Gignac mine was a placer gold drift mine at Texas Hill, two and one-half miles southeast of Placerville. It was active during the 1890s.

The Giltedge mine was a placer gold mine located two and one-half miles south of the town of Fair Play. Active in 1896 when an ancient river channel, capped with sand and clay, was developed by driving a 300-foot adit under the cap to get at the coarse gold on the bedrock.

One mile southeast of Greenwood was a seam gold mine also known as the Gilt Edge (Revenge Consolidated) mine. In the early days of the Gold Rush it was worked by hydraulicking.

The Ginafalio placer mine was near Salmon Falls on or near Sweetwater Creek and the South Fork of the American River.

The Givani Romelli claim consisted of 20 acres somewhere in the general area of Georgetown.

The Glenn mine was a chromite mine located 2 miles southeast of Latrobe. Although it was in an area rich in chromite, it was not mined but only prospected in 1918.

The Gloriana mine was a lode gold mine at Henry’s Diggings two miles north of Omo Ranch, in the southern part of El Dorado County. When it was last reported on in 1956, it had been “long idle.”

The Goethe placer mine was located on the South Fork of the American River, one mile downstream from Lotus.

The Gold Bug mine was a chromite mine four miles southeast of Latrobe on a ridge east of Big Canyon Creek. 16 tons of chromite ore was produced from this mine in 1918. This deposit of low-grade ore, 1 to 3-feet wide and 125 feet long, was developed by open cuts. Another Gold Bug mine (also known as the Canyon Creek Mine) was a placer gold mine two miles north of Georgetown, just north of Georgia Slide Mine. This was mostly a secondary mining operation since accumulated hydraulic mine tailings, seam deposit detritus and some virgin gravel were intermittently worked by several different operators from around 1896 to 1934. The material was extracted by draglines and sent through a trommel (screen) and sluices. A third Gold Bug mine, this time a lode gold mine, was located on 15.35 acres of land on the south side of Sand Mountain, about two miles west of Pino Grande on the north side of the South Fork of the American River.

The Gold Channel placer mine consisted of workings within six different sections of land about seven miles northeast of Georgetown and directly north of today’s Camp Chiquita.

The Gold Deposit lode gold mine was located on an undisclosed amount of land in the area of Kelsey.

The Gold Divide lode gold claim existed, but is not accurately described as to location in the records.

The Gold Dyke lode gold claim was located about one-half mile east of Sacramento County, north of Green Valley Road.

The Gold Hatchet placer mine was on or near the North Fork of Weber Creek, two miles east of Camino.

The Gold Hill placer mine was located on 80 acres one mile south of Coloma in the Gold Hill area.

The Gold Mountain lode gold mine was located on 17 acres of the Mother Lode at Nashville.

The Gold Note Consolidated lode gold mine consisted of several claims comprising 142 acres two miles to the southeast of Omo Ranch. This mine is another one that has been idle so long that not much is known about it.

The Gold Reef lode gold mine was part of a group of nine mines on about 150 acres of a small branch off the Mother Lode that were worked together, three miles south of the town of El Dorado.

The Gold Seam lode gold claim was located just south of the Middle Fork of the American River, just east of Spanish Dry Diggings.

The Gold Slide placer mine consisted of 50 acres on the Middle Fork of the American River, just up stream from its convergence with the North Fork.

The Gold Stake lode gold claim was located on the Mother Lode, two miles south of the town of El Dorado.

The Gold Star lode gold claim was located on the Mother Lode, just south of Kelsey.

The Gold Top lode gold mine was located on 21.66 acres of the Mother Lode, two miles south of the town of El Dorado.

The Golden Center lode gold claim was located on the Mother Lode, two miles south of Diamond Springs.

The Golden Egg lode gold claim was located on the western branch of the Mother Lode, one mile east of Greenwood.

The Golden Fleece (Church) lode gold mine was located on 20.58 acres of the Mother Lode, two miles south of the town of El Dorado.

The Golden Horseshoe lode gold mine was located on the Mother Lode one mile northwest of Placerville.

The Golden State mine was a seam gold mine on 17.91 acres of land just west of Jones Hill and one mile east of Spanish Dry Diggings. The deposit consisted of numerous quartz bearing seams in a belt 200 to 300 feet wide. It was mined by open cut and the material then run through a sluice.
