Two of the most famous mining sites in American history were the Comstock Lode and the Klondike. The Comstock Lode is located in West Nevada and was discovered in the 1880s. The richest silver-mining region in the history of the U.S., it was named after investor Henry T. P. Comstock who sold out early with a small profit. $300 million in silver and gold ore was taken from the Comstock Lode. Just as importantly, many innovations in mining techniques developed there encouraged more exploration and so discoveries of mining sites.
The Klondike is an area in Yukon Territory in Canada, near the border of Alaska. In 1896, gold was discovered there at Rabbit
Creek, launching a huge gold rush in 1897. By 1910, when the rush ended, over 30,000 people had taken more than
$100,000,000 worth of gold from the Klondike.
