In a letter dated May 4, 1862, he wrote to his brother Orion: " Yesterday we took a spirit level and got the angle of the celebrated "Antelope" ledge, and tomorrow we shall commence a hunt after the second E. extension of it. We may find it and we may not. The thing has often been tried before, but with no success. If we find it, our fortunes are made - if we don't - they isn't. I have 5 feet in a spur of the "Antelope", which promises nothing save that it is an offshoot from a good family - and I am aristocrat enough to attach some importance to that sort of thing" On May 5 he writes, "Hunted for Antelope" today and found a ledge - but hardly think it is the right one. Four of us boys have dug two trenches, each 20 feet long and 6 feet deep, to-day, in the gravelly hill side. Finally, if we do find the "Antelope", we cant care a damn anymore" (Letters from Mark Twain Project) According to the Sacramento Daily Union, the company was incorporated around Feb 1, 1861 - this would put this stock certificate in Utah Territory!The Antelope Silver Mining Co was one of the 3 largest mining companies in the 1860's.Alexander Gamble was a stockholder in two other rich mines in Aurora, the Real Del Monte and Wide West.
