Location and accuracy The Henry Ford shaft is the northernmost shaft on a group of six claims of the McCarty/ American Eagle Mine (LG152). The shaft is at the head of Fairbanks Creek, just east of the Wolf Creek divide. It is in the NW1/2 sec. 28, T. 3 N., R. 2 E., of the Fairbanks Meridian.

Geologic setting

Geologic description

Note: As of 2008, this site and several others in the vicinity are being explored as a single entity by Freegold Ventures Inc. (Freeman, 2008). Considerable new mineralization has been discovered that indicates this is part of a larger mineralized system that is described as a separate ARDF site (LG206).
Although sometimes considered separately, by the 1930s, the Henry Ford deposit was part of or at least mined in conjunction with the the McCarty (American Eagle) Mine (LG152). The upper Henry Ford vein strikes N40E and dips northwest. The quartz vein carries free gold and considerable arsenopyrite. Concentrates from arsenopyrite-rich samples from one of the surface pits contain some gold and 1,600 ounces of silver per ton. The vein is cut in three places by quartz stringers, all of which carry gold (W. J. McCarty, unpublished report, 1932).
