| Location and accuracy | The Gilmore prospect is located on the north side of Fairbanks Creek approximately 1.5 miles downstream from the American Eagle mine (ARDF no. LG152); SW1/4SE1/4 sec.22, T. 3 N., R. 2 E., of the Fairbanks Meridian. |
Geologic descriptionThe Gilmore adit was designed to facilitate exploration and haulage from the Ohio and Mizpah mines however, several new gold-bearing lodes were intersected by the adit. The adit was completed to a length of 800 feet in 1917 (Killeen and Mertie, 1951). The schist through which the adit cuts dips 10 to 15 N. In 1922, the adit was 1,000 feet in length (N 30 E trend), contained cross-cuts at the 700-, 800- and 1,000-foot stations, and connected the Mizpah and Ohio mine workings to the Gilmore mill (Davis, 1922). At the 700-foot station, a thin stringer was followed in a 50-foot long drift to the northwest. At the 800-foot station, the northwest drift is 100 feet long and the southeast drift is 75 feet long. At the 1,000-foot station, the southeast drift runs 150 feet to the upper shaft on the Ohio claim. The northwest drift runs 350 feet to intersect with the 200-foot level of the Mizpah mine (Davis, 1922). No information is available concerning the grade or extent of gold mineralization intersected in the Gilmore adit. | |
