Description

    Rare 1886 Mining Report on the Jupiter Deep Blue Gravel Hydraulic Mining Co. No. 1, Calaveras County, California. 5.75" x 9", seven pages, printed wraps. This report, dated April, 1886, was produced by mining engineer and metallurgist, C. A. Luckhardt at the request of the company's President, Dr. James D. Whitney. The report includes sections on descriptions of the mine and its various components. Late in 1884 California outlawed hydraulic mining because of the devastating effect on the environment. The Jupiter Deep Blue Gravel Hydraulic Mining Company was one of the last companies to use the procedure. Very few examples of this report are known to exist. With the exception of some trivial soiling to the covers and a gnawed top right corner, the pamphlet is in very good condition.

    The pre and post sales experience was wonderful and flawless. Heritage has the best in-house operation I have ever seen and their people are not only professional but fun to work with, especially Steve C.

    As for Heritage's online system… Yes the interface is more complex than what we are used to with SAN but what is behind that interface is amazing for sellers and buyers alike. It is real time and for a real serious auction buyer there is nothing better in the auction industry, bar none.
