Location: The Mathews River occurrence is at an elevation of 3,600 feet on the northeast flank of Wiehl Mountain (sec. 26, T. 33 N., R. 9 W., of the Fairbanks Meridian) approximately 7 miles northeast of Sukakpak Mountain. The reference point is taken from the location shown as loc. 46 in DeYoung (1978). It should be noted that the location shown in Cobb (1972, MF 457) is approximately 1/2 mile northwest of the DeYoung (1978) location; the location is accurate within a 1-mile radius.
Geology: Early reports on this prospect described only galena in Devonian(?) greenstone and greenschist near a contact with Devonian siltstone and grit (Brosg
