These placers were the Geologic processes concentrate gold into two largest and most productive ever discovered in Utah, principal types of deposits: lode (or primary) deposits yielding about $1.5 million in gold. However, they where gold is deposited by gold-bearing solutions were practically depleted by 1900. within rock formations; and placer (or secondary) deposits where gold-bearing rocks are eroded and A gold placer in the Mercur (previously Camp the free gold is concentrated in stream beds. Most Floyd) district in Tooele County was discovered in prospectors began their search for gold by looking for 1870. A few prospectors staked claims but soon placer deposits because they offered quick returns abandoned their endeavors due to the scarcity of with simple equipment.

Disappointed, prospectors again left the district. Then, in 1889, Early Discoveries these ores were rediscovered and the gold successfully recovered using the newly developed In 1847, the primary influx of Utah pioneers, cyanide leaching process. From 1890 to 1900, almost Mormon settlers (members of the Church of Jesus 2 million tons of gold ore were treated, producing Christ of Latter-day Saints), arrived in Salt Lake over 380,000 ounces of gold worth about $8 million.

Therefore, it wasn’t until 1858 that wildfire throughout the West. A stampede of 1,200 a gold discovery was reported. Westbound travelers prospectors followed, creating the “Bluff excitement” on their way to California found gold at Gold Hill in in the winter of 1892–93. After enduring hardships, Tooele County.
