By 1904, after investing his winnings in the Boston-Tonopah Mining Company, Wingfield was worth $2 million. When old friend George S. Nixon, a banker, arrived in town, Wingfield invested in his Nye County Bank. They grub-staked (provided with food, supplies and tools in an exchange for a percentage of mine yield) miners with friend Nick Abelman, and bought existing mines. By the time the partners moved to Goldfield, Nevada and made their Goldfield Consolidated Mining Company a public corporation in 1906, Nixon and Wingfield were worth more than $30 million.
