Conditions Governing Access

The Jumbo Extension Mining Company incorporated as successor to the Jumbo and Vernal Extension Mining Company in April 1904. Office and mining property was located in Goldfield, Nevada. The company met with limited success until the discovery, in October 1914, of a rich orebody extending from about the 800 foot level to below the 1000 foot level in the latite and along the latite-shale contact. In February 1915, the Reorganized Booth Mining Company filed an apex suit against the Jumbo Extension to recover damages on the grounds that the new orebody was apexed in the Booth ground. The suit was settled by the payment of substantial stock and cash to the Reorganized Booth Mining Company which in turn entered into side-line agreements with the Jumbo Extension. Subsequently, similar side-line agreements were made with the Goldfield Consolidated and Goldfield Merger Mines Companies so that the property is protected from similar future litigation.
In November 1931, the Jumbo Extension claims were obtained by H. P. Kervin, who later transferred it to the Goldfield Operators, Ltd. During 1932, the mine was partially re-opened for the company by leasers who were given financial and engineering assistance by the company. By 1933, the company was reorganized again as the Jumbo Extension Mining Company under the laws of the state of Nevada in a way as to protect the company's assets and preserve the organization.
