The Midway prospect is on land selected or coveyed to Doyon Ltd. For further information, contact Doyon Ltd. at 210 1st Ave., Fairbanks, Alaska, 99701.
Location: The Midway prospect is located along a south-facing slope of an east-west ridgeline at an elevation of 1,400 feet (427 m) about 1.75 miles (2.8 km) northeast of the Reef Ridge deposit, in Section 18, T. 24 S., R. 24 E., of the Kateel River Meridian. Location is accurate to 100 feet (30 m).
Geology: The Midway smithsonite prospect is located along a break in slope in limestone and dolomite of the Telsitna Formation of Dutro and Patton (1982). The Midway occurrence is mainly manifested in anomalous lead and zinc in springs and seeps that occur along a break in slope. Smithsonite was identified in solution breccias exposed in rubble. Most of the prospect area is covered by vegetation. A soil grid established a 500 feet by 800 feet (152m by 244 m) anomalous zone which averages 250 ppm zinc and 100 ppm lead. Nearby stream sediment sampling yielded up to 176 ppm lead and 500 ppm zinc (Andrews and Rishel, 1982).
Workings: The Midway prospect was found by WGM Inc. and Patino Ltd. during exploration for base metals in the late 1970s on lands selected by Doyon Ltd. A soil grid established a 500 feet by 800 feet (152m by 244 m) anomalous zone which averages 250 ppm zinc and 100 ppm lead. Nearby stream sediment sampling yielded up to 176 ppm lead and 500 ppm zinc (Andrews and Rishel, 1982).
