Detailed, scientific geological mine mapping began in the early years of the twentieth century with the work of Reno S ales at Butte , Montana. The mapping was done in-house for the An aconda Copper Company, but the results were subsequently published in a monumental work (Sales, 1913). The instigation for this work was partly to solve legal disputes consequent upon the North American Ap ex Law of mineral ownership, but the value of quality geological mapping in the search for extensions to ore and in the development of theories on ore genesis was recognized early on.
