Perhaps it was those millennia of experience that, in 1873, led four Irishmen – Mackay, Fair, Flood and O’Brien – to the Comstock Lode, the greatest pot of gold and silver the world has ever known. They located an enormous silver heart within Mount Davidson in Nevada.
The first to putter around above the great trove were a couple of surface gold miners named Peter O’Riley and Patrick McLaughlin. These men did not know about nor have the resources to mine down thousands of feet to the silver; they panned for gold and moved on, not realizing that a blue sand that clogged their simple wooden machinery, was in fact silver mixed with gold. Assayed later in 1859 by other men, this sand proved to be “almost a solid mass of silver,” and the silver rush was on.
Eventually it took stockholders, powerful machinery, new mining techniques, and millions of dollars to penetrate the pile and extract billions in silver and gold. Chief among those who pioneered and benefited from the lode were the four Irishmen.
