Utah’s mining history centers on copper, gold, silver, and beryllium, with copper remaining the most valuable mined product as of 2026.
What is the most valuable mined product in Utah?
Copper is the most valuable mined product in Utah, contributing nearly $4 billion to the state’s economy annually.
No other mineral comes close. Utah’s copper production is dominated by the Kennecott Utah Copper mine, one of the largest open-pit mines on the planet. Since opening in 1906, Kennecott has produced over 20 million tons of refined copper. The mine also yields significant amounts of gold, silver, and molybdenum as byproducts. According to the State of Utah, copper mining remains a cornerstone of the state’s economy, with Utah ranking among the top copper producers in the U.S.
What did Utah mine?
Utah historically mined lead, zinc, copper, iron, coal, gold, and silver, among other minerals.
The 1800s and early 1900s brought prospectors by the thousands. Word spread fast about Utah’s rich ore deposits. Silver booms in the late 19th century made some miners rich overnight. Coal mining, meanwhile, powered Utah’s industrial growth for decades. The U.S. Geological Survey notes that Utah was once the nation’s leading producer of lead and zinc, though production has declined in recent decades.
What is being mined in Salt Lake City?
Salt Lake County hosts active mining operations focused primarily on copper, gold, and silver, with Kennecott Utah Copper as the dominant producer.
| Mineral | Primary Operations | Status |
|---|
| Copper | Kennecott Utah Copper | Active (open-pit mine) |
| Gold | Byproduct of copper refining | Recovered annually |
| Silver | Byproduct of copper refining | Recovered annually |
Right in the backyard of Salt Lake City sits the Bingham Canyon Mine, run by Rio Tinto Kennecott. It’s the most prominent operation in the area. For the latest list of permitted mines, check the Salt Lake County government website—they keep the records current.
What is mined in Utah County?
Utah County has historically produced silver, lead, and gold as primary commodities.
The Oquirrh Mountains, especially around Bingham Canyon, were once Utah’s gold rush hotspot. Big-scale mining has slowed, but you’ll still find small-scale prospectors and weekend rockhounds out there. The Utah Geological Survey keeps detailed records of old mining claims. Utah County also has several limestone quarries feeding the cement and construction industries.
Where can I dig for gems in Utah?
Top locations to dig for gems in Utah include Topaz Mountain, Dugway Geode Beds, and the Stansbury Island area.
- Topaz Mountain (Thomas Range): Famous for high-quality topaz—the state gem. You’ll find specimens embedded in volcanic rhyolite formations.
- Dugway Geode Beds: West of Salt Lake City, this spot is packed with geodes lined with quartz and calcite crystals. Just make sure you’ve got permission to collect before you go.
- Stansbury Island: Known for tiny diamonds, especially in the northern reaches near the Great Salt Lake.
- U-Dig Fossils (Delta): A fee-dig site where families can crack open trilobites and other fossils.
Want the full list of legal collecting spots? The Utah Geological Survey and local rockhounding clubs have you covered. Always double-check land access and follow environmental rules—no shortcuts.
How many abandoned mines are in Utah?
Utah has approximately 17,000 abandoned mines, with about 6,000 reclaimed by the Abandoned Mine Reclamation Program as of 2026.
The Utah Division of Oil, Gas, and Mining runs the Abandoned Mine Reclamation Program. They focus on the most dangerous sites first. Many of these mines date back to the late 1800s and early 1900s, back when safety rules were practically nonexistent. Bottom line? Never, ever enter an abandoned mine. The Utah Division of Oil, Gas, and Mining has an interactive map showing reclaimed and active sites. As of 2026, work continues to tackle the remaining unclaimed mines.
What is the richest mine in the world?
Jwaneng Mine in Botswana is widely regarded as the richest mine in the world, owned by Debswana.
This isn’t just a diamond mine—it’s the diamond mine. Since opening in 1982, Jwaneng has churned out gem-quality stones that dominate the market. It consistently ranks as the highest-value diamond mine globally, accounting for 60% to 70% of Debswana’s total earnings. De Beers, the operator, calls it the “richest diamond mine” thanks to its high ore grades and massive output. For comparison, Utah’s Bingham Canyon Mine is the largest open-pit mine by volume, but it mostly produces copper and byproducts. Data comes from the De Beers Group and industry reports.
What are the 5 largest reservoirs in Utah?
The five largest reservoirs by surface area in Utah are Bear Lake, Utah Lake, Lake Powell, Flaming Gorge Reservoir, and Strawberry Reservoir.

|---|
| Bear Lake | 69,760 | Recreation, irrigation |
| Utah Lake | 95,000 | Recreation, wildlife habitat |
| Lake Powell | 161,390 | Water storage, recreation |
| Flaming Gorge Reservoir | 42,020 | Fishing, boating |
| Strawberry Reservoir | 17,164 | Water supply, fishing |
These reservoirs are managed by a mix of agencies, including the Bureau of Reclamation and the Utah Division of Water Resources. Water levels shift with the seasons and drought cycles, so check the Utah Water Resources Data for real-time updates.
Are diamonds found in Utah?
Diamonds can be found in northern Utah, particularly on Stansbury Island in the Great Salt Lake.
Yes, really. Small, gem-quality diamonds have turned up in gravel deposits on Stansbury Island. Historical records from the Utah Education Network confirm finds, though most are under one carat. Prospectors need land access permission and must follow state rules—collecting on protected lands is a hard no. The spot is easy to reach via Exit 84 on Interstate 80, just west of Salt Lake City.
How deep is the Kennecott mine in Utah?
The Kennecott mine (Bingham Canyon Mine) extends more than 1.2 kilometers (over 3,900 feet) deep and spans approximately 4 kilometers (2.5 miles) wide.
It’s the deepest open-pit mine on Earth. Since 1906, the mine has produced over 19 million tons of copper. Kennecott Utah Copper, a Rio Tinto subsidiary, still runs the operation today. While copper is the star, the mine also delivers gold, silver, and molybdenum. Don’t expect a tour—the site isn’t open to the public. The Rio Tinto Kennecott website keeps the public updated on operations and environmental efforts.
Is there silver in Utah?
Yes, Utah remains an important producer of silver, with historical and ongoing mining operations.
Back in 1983, Utah accounted for 10.5% of U.S. silver production. The Hecla Mining Company’s Escalante Mine in Iron County is one of the top silver producers in the country. Silver mining has slowed since the mid-20th century, but Utah still ranks in the top 10 silver-producing states. The National Mining Association reports that silver is usually a byproduct of copper, gold, and lead mining. For the latest production numbers, the Utah Geological Survey has the data.
What is the largest open pit mine in the world?
The Bingham Canyon Mine (Kennecott Copper Mine) in Utah is the largest open-pit mine in the world by volume and depth.
This Utah giant stretches about 7.7 square kilometers (3 square miles) and plunges over 1.2 kilometers (3,900 feet) deep. It’s been running nonstop since 1906 and is owned by Rio Tinto Kennecott. The mine is so massive it’s visible from space and has produced more copper than any other mine in history. The Rio Tinto annual report highlights ongoing expansion and sustainability work.
Is there gold in Utah County?
Yes, gold has been found in Utah County, particularly in the Oquirrh Mountains and Bingham Canyon area.
Bingham Canyon was once the site of one of Utah’s biggest gold placer finds. Commercial mining has tapered off, but you’ll still see recreational prospectors panning for small flakes in streams and gravel beds. The Prospectors and Miners Association sells maps and guides for gold panning in the region. Utah County isn’t as rich as Nevada or Colorado, but gold is definitely there in trace amounts.
Where is gold found in Utah?
Gold is found in several regions in Utah, including the Abajo Mountains, Oquirrh Mountains (Bingham Canyon), and the East Tintic Mountains.
- Abajo Mountains: Gold shows up along Johnson Creek and Recapture Creek, mostly in placer deposits.
- Oquirrh Mountains (Bingham Canyon): Once Utah’s largest gold placer, now part of the Kennecott mine complex.
- East Tintic Mountains: A lesser-known area with historical placer and lode gold deposits.
If you’re planning to prospect, the Utah Geological Survey has public-land maps where mining is allowed. Always verify federal and state rules—some spots are off-limits or need permits. The Bureau of Land Management manages many public lands open to mineral prospecting in Utah.
Where is salt found in Utah?
The Bonneville Salt Flats, located along Interstate 80 near the Utah-Nevada border, is the primary source of salt in Utah.
The Bonneville Salt Flats cover more than 30,000 acres and are what’s left of ancient Lake Bonneville. The salt crust varies in thickness and is harvested commercially for water softeners, food processing, and de-icing products. The area is also famous for land speed racing. The Utah State Parks manages access to the Bonneville Salt Flats, which is federally protected. Salt also turns up in the Great Salt Lake and other alkaline lakes across western Utah.
