(originally the UNION MINING DISTRICT)

in Washington County, Utah


The Silver Reef mining district consists of four "reefs" on the northeast nose of the Virgin anticline. These are the White Reef, Buckeye Reef, and Butte Reef on the anticline's northwest flank and the East Reef is on the anticline's east flank.

See the map.


John Kemple and others (most of the family heads at Harrisburg and some of the leaders of St. George) organized the Union Mining District in 1871. They filed the first mining claims in Silver Reef.

Kemple returned to Silver Reef in 1874 and reorganized the old Union Mining District as the Harrisburg Mining District. The Harrisburg Mining District record books contain the minutes of early meetings held by the miners and the by laws adopted for the district. Thereafter, they contain primarily mining claims or notices of location. For each notice the mining district recorder reported the names of locators, the name of the mining claim, and a legal description of the location. In addition to notices of location, the mining record books include other mining documents such as, mining deeds, documents validating labor performed on claims, documents about water rights, notices of relocation, protests against notices of location, amended notices, and maps identifying the location of particular claims.

High-grade silver chloride float was first discovered near Harrisburg in 1866. In-situ mineralization was found in 1868 and John Kemple filed the first claim in 1871.

Finding silver in sandstone was so unheard of, the it took a while for the disbelief to lift. But by 1876, the silver rush was on and principal mining activity continued through 1888. The decline from the boom years was due to a number of factors including decline in silver prices, increase in production costs as the mines went deeper, reduction in the quality of the remaining ores, and flooding in the mines.

Then lessee operations continued from 1889 through 1909, after which major mining essentially ceased.

During the next few decades, several large companies consolidated the mines and did some exploratory work, but no real production resulted.

From 1950 to 1958, there was some uranium exploration and production in the district.

A leach-pad operation established between White and Buckeye Reefs to process tailings opened in 1979, but this venture closed with the collapse of silver prices. The district continues to be periodically explored, but no serious mining has taken place.

Reclamation of the White, Buckeye, and Butte Reefs, was completed during the period from 1996 to 1997. It involved 465 mine closures at a cost of $469,000 and was the largest single mine closure project for the Utah Division of Oil, Gas and Mining, Abandoned Mine Reclamation Program to date. Reclamation of 184 mine openings at the East Reef area was completed in 2000 at a cost of $170,000.
