The Florence prospect (Cobb, 1980 [OFR 80-363]) is on the north spur of Wickersham Dome at an elevation of about 3550 feet. It is in the SW1/4 NE1/4 section 6, T. 15 S., R. 17 W., Fairbanks Meridian. The location is accurate within 300 feet.

The country rock at the Florence prospect is quartz mica schist of the Precambrian Birch Creek Schist (Bundtzen, 1981; Thornsberry, McKee, and Salisbury, 1984, v. 2, occurrence 44). Exposures are poor, but the trace of float across the area suggests that the deposit is a sulfide-bearing quartz-siderite vein that strikes about N 40 E. A shaft and trench were caved by 1931, when Wells (1933, p. 370) visited the Florence property. He reported fine-grained galena and tetrahedrite, and that the rocks were stained with malachite. The prospect subsequently was explored by bulldozer trenches, which exposed oxidized ore that contained abundant anglesite, azurite, cerussite, goethite, and malachite. Bundtzen (1981) reported sphalerite, stibnite, and polybasite in remnant fragments of fresh ore.

Some of the ore is moderately rich in silver that seems to be associated with galena, but there is essentially no gold. The richest sample assayed 70 ounces of silver per ton and 70 percent lead. Another sample containing only 4.55 percent lead assayed almost 40 ounces of silver per ton. Both samples contained about 1.5 percent copper, suggesting that tetrahedrite or another copper-bearing mineral is present (Bundtzen, 1981; Thornsberry, McKee, and Salisbury, 1984, v. 2). Samples collected by Hawley and Associates (1978) contained up to 50 percent lead, 1.35 percent copper, 5.2 percent zinc, and 3.1 percent antimony.
