COLUMBUS GOLD CORPORATION : http://www.columbusgoldcorp.com/ : Silver District Property
Silver District Property
The Silver District Property consists of 103 mineral claims, totaling approximately 2763 acres, covering the historic Silver District in southwest Arizona. Subject to a net smelter royalty, Columbus owns a 100 percent interest in the property.
Historical (19th Century) production totaled approximately 1.5 million ounces silver. Modern exploration was carried out between 1975 and 1992 by The New Jersey Zinc Company and Orbex Minerals and included extensive resource delineation drilling, metallurgical test work and feasibility studies.
Past programs delineated a resource of 3,820,000 tons grading 4.60 ounces per ton silver (17,500,000 ounces) plus potentially commercial fluorite, barite and zinc-lead in a number of deposits. More than half of the identified resource occurs on Columbus Gold's claims and Columbus is pursuing negotiations to acquire additional claims to increase its interest in the identified resource.
Past programs and studies indicate that the deposits are potentially mineable in low strip ratio open pits and amenable to recovery by flotation followed by cyanidation.
Three major vein systems, with collective strike lengths of plus eight miles, provide good potential for resource expansion.
Columbus plans on consolidating the identified resource through low cost acquisition of claims and leases abandoned by previous owners. An exploration program to expand the resource base will be followed by an economic scoping study to update past feasibility studies based on current conditions.
