Discovered in 1981; production began in 1986 from a combination of patented and unpatented mining claims which will be owned or controlled by SFPM.
In 1993 and 1994, SFPM will examine Mule Canyon's potential as a commercially viable project.
In 1993, SFPM will continue drilling and evaluation.
Other Exploration Projects: SFPM also received a portfolio of seven other gold exploration projects located in the United States, principally in Nevada; four gold exploration projects in Canada, two in northwestern Ontario and two in western Quebec; six exploration concessions in Chile; and an exploration program recently initiated by Gold Fields in Mexico.
With an estimated combined initial annual gold production rate of more than 750,000 ounces and gold reserves estimated to be more than 11 million ounces, SFPM will become one of the top six North American gold producers.
The two operating gold mines to be acquired by SFPM are the Mesquite Mine in Imperial County, Calif.
SFPM anticipates that the joint operation of Chimney Creek with its adjoining Rabbit Creek Mine will produce operating efficiencies and will increase both annual gold production and recoverable reserves.
SFPM is one of the largest private mineral land holders in the western United States, with some 7.
and drill size are defined as variables (#542 and #540 in the example above) and the control automatically calculates the rpm.
Vitrified bonds are commonly used to 6,500 SFPM
or in selected operations up to 12,000 SFPM
Indexable drills have the problem of zero cutting speed at the center even though speeds can exceed 1,000 SFPM
at the outermost inserts.
range recommendations for tool and work materials are given in many reference publications.
