Assay receipt book from the Gould and Curry Mining Company containing assay receipts from September 3rd, 1864, through January 10th 1865 taken at their mill; a total of 329 assay receipts. These assay reports come from three locations; West Battery, Dalls Mill, and the Tailings Plant. The assays include samples from various batteries of stamp, pans and tailings. Ore samples were furnished by three persons through this period. F.A.P. (F.A. Parker, a clerk at the G &C Mill - ref. Collins 1864 Directory p. 179), L.A.P.??? and Louis Janin. Janin went to the Comstock mines in Nevada, where he advanced rapidly as a metallurgist at the Mexican Mill, as an assayer at the Silver State Reduction Works and becoming superintendent of the Gould and Curry Company in 1864. 5.5x5", receipt pad with cover cut to match receipt size.

Some receipts FH highlighted: receipt # 2742, 1864, is way too high with $13.56 gold and $73.72 silver. Receipt #2741 from a sample obtained by Bonner, has $70.83 gold and $174.75 silver from crusher at Dall's Mill. Receipt 2803 from Janin, tailings from the reservoir $15.07 gold and $78.14 silver. Receipt 2806, tailings from the reservoir $15.07 gold and $72.70 silver. This is an exceptional record of 1864 production with ore running $60-150/ton.

The Gould & Curry Mill was built at considerable cost in 1862 and located at the confluence of Sixmile and Sevenmile Canyons. By the end of 1863, approx. $900,000 had been spent. Charles Strong was replaced as supt. by Charles Bonner, and the mill was reconstructed for a cost of $560,000. It used both stamping mills and a variant of the Washoe Pan Process (Veatch Process) along with Spanish style Patio Process.
