Next meeting Monday, November 11, 2019:

6RSHwzrwThe Bonanza King author Gregory Crouch will discuss John Mackay, who got his start in the United States as a destitute Irish immigrant brought here when he was 9 years old. Mackay grew up in New York City’s Five Points slum (“The Gangs of New York neighborhood), came of age amid the violent mayhem of the California Gold Rush, and rose to manhood in the deep, rich, and outrageously dangerous mines of the Comstock Lode beneath Virginia City, Nevada.

On the Comstock, Mackay worked his way up from nothing, battling the pernicious “Bank Ring” of California capitalists who’d monopolized the lode, and struck the legendary Big Bonanza, a stupendously valuable body of gold and silver ore buried 1,500 feet below the center of the town. The extraordinary wealth Mackay extracted from the Comstock Lode drove wild stock market frenzies in San Francisco. When John Mackay died in 1902—with a personal fortune equivalent to about $50 billion modern dollars—front page obituaries all over Europe and the United States hailed him as one of the most admired Americans of the age.

Gregory Crouch is a writer who specializes in adventurous and historic subjects. He is the author of the Comstock epic, The Bonanza King: John Mackay and the Battle Over the Greatest Riches in the American West, the World War II flying adventure China’s Wings: War, Romance, Intrigue, and Adventure in the Middle Kingdom In 1988, Gregory Crouch graduated from the United States Military Academy at West Point, New York, where he studied military history. During his active service, he completed U.S. Army Airborne and Ranger schools and led two infantry platoons.

More news:

There will be NO Gem-O-Rama in 2019.
TRONA GEM-O-RAMA – URGENT ANNOUNCEMENT

On August 6 Searles Valley Minerals Inc. notified the Searles Lake Gem & Mineral Society that the strong earthquakes on July 4 and 5 damaged their facilities to such an extent that SVM will not be able to host any Gem-O-Rama gem show activities on their properties during this year’s gem show. The SVM exclusion includes all access to Searles Lake to collect saline minerals, including Searles Lake pink halite, and all tours through their manufacturing facilities. Because these activities form the backbone of the Gem-O-Rama, we believe that we must cancel the 2019 Gem-O-Rama in Trona, California.

Please help us by passing this information on to any person or any organization that you think might be interested in attending the Gem-O-Rama in 2019 so that they won’t be surprised and disappointed if they try to attend.
