Lot of 2. 1. The Henrietta Milling and Mining Company. No. 733 issued to A. H. Savin by Geo. H. Craft, Secretary, and E. C. Drew, President on 18 September 1909 for 154 shares. The Henrietta Mine was in Prospect Gulch, which leads into Cement Creek, and just to the southwest of Gladstone. There are four tunnels on the south side of the gulch. The main adit was 150 feet above the bottom of the gulch. The ore was primarily pyrite and chalcopyrite and contains no quartz. The tenor was low, assaying at .05 to .10 gold, and 12 to 30 ounces of silver per ton. Copper assays as high as 302 [Refs: Ransome, F. L., “Economic Geology of the Silverton Quadrangle, Colorado,” USGS Bull. 102, 1900; The Hal Miller Files]. This stock is on crème paper with a black border and an inner gold border. Vignette of a bald eagle with wings outstretched over the company masthead. The folds are visible and the right edge has little tears. U/C. Good condition. 2. Southern Colorado Bismuth & Silver Mining and Smelting Company. No. 1498 issued to George C. Phelps by D. S. Critchley, Secretary, and Edwin Fowler, President, on 5 April 1884 for 25 shares. Theodore Stahl, former superintendent of a reduction works for the Russian government in Siberia, invented a new process for the reduction and recovery of bismuth and silver in his laboratory in Howardsville, CO. He found bismuth on Bonita Peak and located the Sampson claims along with the Golden King and a number of others. By mid-June there were 25 men at work on both the mines and erection of the mill building. A complex of buildings was erected on the North bank of the stream including a 50 x 85r mill building, a detached boiler plant and a 20 x 401 boarding house. The mill had a 40 horse power engine and boiler, a Blake crusher, two sets of Cornish rolls, four double compartment jigs, and two revolving screens. By late September, most of the work had been completed on the Sampson No. 2. The uppermost of the two levels drifted for 160’ on the vein originally located by Stahl. As John Engel and his men drifted on the veins, the ore changed from the grayish bismuth to solid white quartz rich in gold. Some of the ore assayed from 5000 to 8000 oz./ton of gold. The first cable-tramway in the San Juan’s was constructed and D.S. Critchley reported in December that the tram was working. The Sampson mill started up October 18, 1883, and by then 60 men was employed. A March 1884 avalanche destroyed much of the tramway and a good portion of the mill buildings, and another in 1886 demolished the boarding house [Ref: Nossaman, Allen, Many More Mountains, Vo1. 3, 1998]. This stock is on crème paper with a black border. Not especially ornate but it has an unusual vignette of a hand holding the company masthead as if it were a business card. Stamped above the signature line “Full Paid and Non-Assessable.” The folds are yellowing on the reverse but otherwise it is in good condition.
