A Golden Beginning
People first started looking for gold in this area around the 1850s. Mexican miners used simple tools called arrastras to find gold in the riverbeds. Later, a Frenchman named Mache is thought to have started the Good Hope Mine. The main gold vein, which was a rich source of gold, was discovered in 1874. After that, American miners bought the mine and began to work it more extensively.
Digging for Gold
Miners dug deep into the earth at the Good Hope Mine. The mine reached a depth of 575 feet. Inside the mine, there were several levels, each about 100 feet apart. The first two levels, at 250 and 350 feet deep, stretched for almost 1,000 feet. This shows how much effort went into finding the gold.
Where Gold Was Hidden
The gold at Good Hope Mine was found in a type of rock called granodiorite. At the surface, there were several gold veins that were close together. As miners dug deeper, these smaller veins joined to form a larger, more irregular vein. The gold was often mixed with iron sulfide inside the quartz rock.
Getting the Gold Out
To get the gold out of the rock, the ore had to be crushed. In 1881, a railroad line was built nearby. This made it easier to bring in equipment. A "five-stamp mill" was built to crush the ore. Later, in the 1890s, a company called the Good Hope Mining Company took over. They brought in a much larger "twenty-stamp mill," which was powered by coal.
Challenges at the Mill
The gold ore from Good Hope Mine was tricky to process. It needed to be crushed very finely. Also, it required careful use of water and special machines to separate the gold. After the big twenty-stamp mill was installed, there wasn't enough water to run it efficiently. This meant that a lot of gold was left behind in the waste material. Later, other operators used a process called cyanidation to recover this leftover gold, which was still quite valuable. If the mine had focused more on efficiency and less on crushing huge amounts of ore, they would have gotten more gold themselves.
Mine's End and Legacy
The Good Hope Mine produced a lot of gold. Before 1896, it had already produced about $2 million worth of gold. The mine operated steadily until around 1903. In the 1930s, there was an attempt to reopen the mine, but it wasn't very successful. The Good Hope Mine eventually closed because it became flooded with underground water.
Today, the mine site is located between Lake Elsinore and Perris, just west of Highway 74. The workers who lived near the mine formed a community that took the mine's name. This area is now a populated place called Good Hope.
