Alluvial Prospecting and Mining Book Summary : Alluvial Prospecting and Mining (Second Revised Edition) focuses on the emergence of improved mining techniques and methods used in the excavation of alluvial deposits.
· Alluvial gold placers, for example, form very narrow strips so that exploratory holes must be closely spaced -- 10 to 20 m apart -- within lines at 400--800 m intervals. Tin placers are distinguished by their greater width and smaller length; therefore exploration works are located approximately 20--40 m apart and the lines are not more than 400--600 m apart.
