This so-called "Big Bonanza" made "John William Mackay" the richest man in the world, since the discovery led his business shares to the point where he was valued at roughly 1 billion dollars.
The "Big Bonanza" in 1873 made John W. Mackay the richest man in the world due to the massive silver discovery in the Comstock Lode, which significantly impacted the U.S. economy. This discovery was part of a larger wave of mining successes in the western United States during the 19th century. Mackay's operations capitalized on the enormous wealth generated from silver mining in Nevada.
