Location: The Scott Reese prospect, formerly known as the Rex prospect, is located approximately one half mile southwest of the Blue Moon Mazeppa prospect (ARDF no. LG128) on lower Chatham Creek; SW1/4SE1/4 sec. 19, T. 3 N., R. 2 E., of the Fairbanks Meridian.
Geology: Free gold is found in 3-inch quartz stringers that strike N 60-75 E and dip 25 SE (Pilgrim, 1932; Stewart, 1933). Prior to 1931, the shear zone had produced a small amount of ore that averaged $8.50 per ton in gold (0.4 ounces of gold per ton) (Pilgrim, 1932).
Workings: The prospect was staked as the Rex claim in 1911 by W.S. Reese who conducted a minor amount of exploration in that year (Times Publishing Company, 1912; Brooks, 1912). Legal problems prevented additional work and in 1912 no work was conducted (Smith, 1913; B 525). By 1931, a 320-foot adit had been driven on the Rex shear zone (Hill, 1933). This adit intersected a 4-inch-thick fault zone 20 feet from the portal and a 3-inch quartz-bearing shear 150 feet from the portal. A 3-foot-thick, northeast-striking shear was intersected 72 feet from the portal and had produced a few tons of ore averaging $8.50 per ton in gold (0.4 ounces of gold per ton) prior to 1931 (Pilgrim, 1932). The adit intersected a fault zone oriented N 60 E, 80 SE, about 230 feet from the portal. At the 258-foot station of the tunnel, drifts had been driven on a N 60 E shear zone. The northeast drift had followed this shear for 45 feet and the southwest drift was extended 100 feet. Free gold was recovered from a 3-inch-thick quartz stringer near the face of the northeast drift; the stringer had an east-west strike and a 45 S dip. Approximately 40 feet from the main adit, the southwest drift intersected a 3-inch-wide, N 75 E, 25 SE. quartz stringer which also contained free gold (Pilgrim, 1932; Stewart, 1933). W.S. Reese still owned the prospect in 1938 when a small amount of work was conducted in the main adit (Reed, 1939).
Production: Prior to 1931, the shear zone had produced a small amount of ore that contained an average of $8.50 per ton in gold (0.4 ounces of gold per ton) (Pilgrim, 1932).
