Leading mining historian Kerby Jackson introduces us to a classic mining publication on gold recovery by Edward Preston. Unavailable since 1895 and released under the name "California Gold Practices," this rare publication provides an in depth look at early methods of milling used to reduce gold ores in California during the late 19th century. This volume provides a reference into the early development and use of milling equipment during the earliest years of the California Gold Rush up to the age of the Industrial Revolution. Much of the information still applies today and will be of use to small scale miners engaging in hardrock mining. Note: This edition is a perfect facsimile of the original edition and is not set in a modern typeface.
