Journigan’s Mill

Journigan’s Mill (also known as the Gold Bottom Millsite) was a custom amalgamation-and-cyanide gold mill in Emigrant Canyon, Death Valley National Park (Inyo County, California). It was the largest and longest-operating mill of its type remaining in the park from the 1930s–1950s era and played a key supporting role in the mid-20th-century revival of gold mining in the Skidoo/Harrisburg and Emigrant Spring areas.

Location and Physical Setting

The site sits on the west side of Emigrant Canyon Road (also called Wildrose Canyon Road), roughly 1 mile south of Emigrant Springs and about 13.5–14 miles south of Stovepipe Wells, at an elevation of approximately 4,400 feet in the Panamint Range. It covers about 3 acres and is highly visible from the paved road.

Water—the critical limiting resource in Death Valley—came from nearby springs (Green, Burro, Willow, and Burns; earlier accounts also mention additional springs such as Canyon and Malapi). Pipelines delivered water to the mill, enabling continuous operation in an otherwise arid environment.

Today the site consists of scattered concrete foundations (mill platforms on multiple levels, housing footings), remnants of cyanide tanks, two steel water tanks (in earlier descriptions), a wooden floor platform, and tailings piles/stockpiles. Machinery was removed long ago. The ruins are eligible for the National Register of Historic Places for their local significance as the largest surviving amalgamation/cyanide plant of the period and for having the longest contiguous use of any milling site within the former Death Valley National Monument.

Early Use of the Site (Pre-Journigan)

The location had intermittent milling activity for decades before Roy Journigan’s major development, taking advantage of the springs:

• Possible early one-stamp mill processing Skidoo ore around 1909 (unconfirmed in some studies).
• Carl R. Suksdorf and Frank “Shorty” Harris reportedly ran a ball mill here in 1918 for custom work.
• Suksdorf filed for water rights to six nearby springs in the early 1920s for his Gold Dollar Millsite (tied to his nearby Gold Dollar Mine) but lost them for non-development.
• Shorty Borden and Shorty Harris purportedly operated a five-stamp mill in 1924 processing Skidoo and Poppy Mine ore.
• Dr. Archibald and later Walter M. Hoover continued intermittent milling into the early 1930s.

These earlier efforts were smaller and sporadic.

Establishment and Operation under Roy Journigan (mid-1930s–1939)

The decisive impetus came from the Gold Reserve Act of 1934, which raised the official U.S. gold price from $20.67 to $35 per ounce. This made lower-grade ores newly profitable and spurred a revival of mining in the region.

In March 1934, Roy Journigan (with partners E.L. Journigan and L.E. Steinberger) located the five-acre Gold Bottom Mill Site claim. Construction of a new 25-ton-per-day amalgamation and cyanide mill began around 1935; sources commonly date the main plant to 1937. Journigan’s business model was to operate a custom mill: local mine owners would truck ore to the mill rather than ship bulky low-grade material long distances to distant smelters. This reduced transportation costs, allowed higher-grade concentrates to be shipped, and created shared profits.

Key features of the plant (from NPS Historic Resource Study descriptions) included:

• 25-ton ore bin and a finer-ore bin
• 6-inch by 8-inch Blake crusher
• 3 × 4 ft Straub cone-type ball mill
• 4 × 8-foot amalgamation plates
• Seven 14 × 5-ft cyanide tanks
• Four-compartment zinc boxes for precipitation
• Powered by a 15 h.p. Fairbanks-Morse gasoline engine

Four men typically worked the mill. In 1937 Journigan leased the Skidoo mine and also processed ore trucked from the Cashier mine at old Harrisburg. The mill stimulated renewed activity around Emigrant Spring and the reopening of Skidoo/Harrisburg-area mines by lowering production costs.

Journigan sold the mill in 1939 (some contemporary reports say 1938). One account notes that the last ore milled under his direct operation was in 1938; subsequent owners used the water rights for related milling, including at Skidoo.

Later Ownership and Continued Operation (1939–late 1960s)

The mill changed hands multiple times and continued operating under various owners into the late 1960s—making it the longest-running mill in Death Valley. It was rebuilt or renovated in the 1950s. In September 1959 the Argentum Mining Company purchased the machinery, dismantled it, and moved it to Columbia Flats (near Mina/Columbus), Nevada. A final effort in the 1960s used the remaining cyanide tanks to leach the tailings dump; this activity ended by 1967 (some accounts extend minor activity into the early 1970s).

Role in Regional Mining and Output

Journigan’s Mill was never a primary mine producer itself; it was a custom processing facility that enabled profitable extraction of gold from relatively low-grade ores in the surrounding Panamint Range districts. By providing local, efficient amalgamation (mercury-based recovery of free gold) followed by cyanide leaching (dissolving remaining gold into a soluble complex for precipitation), it made remote desert mining more viable during the post-1934 gold-price boom and beyond.

Capacity: 25 tons of ore per day.
Primary feed sources: Skidoo mine (under lease) and Cashier mine (Harrisburg); also custom work for other local properties.
Specific production totals (ounces of gold recovered or total tonnage processed across the mill’s life) are not well documented in available NPS summaries or secondary sources. Contemporary notes indicate ore values in the Skidoo area in the mid-1930s were often in the $15–$30 per ton range (at the new gold price). The mill’s contribution was primarily enabling activity rather than generating independently recorded large-scale output figures comparable to the original early-20th-century Skidoo production (which totaled roughly $1.3–1.5 million before 1917).

An estimated 1,500 cubic yards of mill tailings remain on site, reflecting the volume of material processed over decades.

Significance and Present Status

Journigan’s Mill exemplifies the ingenuity required for desert mining: securing water rights, building pipelines, and running a relatively sophisticated (for its remote setting) cyanide plant that extended the productive life of older districts. It is the largest surviving ruin of a 1930s–1950s amalgamation-and-cyanide operation inside Death Valley National Park and documents the longest continuous milling use of any site in the former monument.

Visitors today see only foundations, tank remnants, and tailings. The National Park Service has conducted environmental assessments because of residual cyanide and elevated metals in soils and tailings; the site is managed with “Stay Out – Stay Alive” warnings due to physical and chemical hazards. An interpretive sign recounts the mill’s history for the public.

In summary, Journigan’s Mill operated primarily from the mid-1930s through the late 1960s (peak development and custom milling under Journigan and successors ~1935/1937–1959, with residual activity into the 1960s), processed ore at a capacity of 25 tons per day drawn mainly from Skidoo and Cashier, and served as a critical local processing hub that helped sustain gold mining in the Emigrant Canyon–Skidoo–Harrisburg corridor long after the original boom towns had faded.
