At the Midway occurrence, highly sheared and shattered quartz veins trending north to northwest and dipping 30 to 50 degrees northeast, are traced on surface over 244 metres. The veins are highly variable in width, from hairline to over 2 metres. The veins crosscut Helikian Middle Aldridge (Purcell Supergroup) stratigraphy consisting of quartzites, turbidites and interbedded argillites. The occurrence is located on the west limb of the Moyie Lake anticline near the anticlinal axis. Two adits were driven on the vein, the upper one about 412 metres along strike and the second, located 21 metres lower, was driven about 320 metres but lost the vein at about 218 metres. Due to the regional anticline, the adits cut through progressively higher stratigraphic levels of the Middle Aldridge Formation as they were developed to the west. Records also indicate diorite sills occurring west of the showing within the Upper Aldridge Formation and at the Creston Formation-Aldridge Formation contact.
The vein carries lead, zinc and copper sulphides which have gold and silver values associated. Also reported from shipments are 0.9 per cent tin but the actual mineral is unidentified. Associated with the lead is 0.4 per cent antimony.
Intermittent mining, 1933 to 1962, produced 85,534 grams of silver, 9082 grams of gold, 2549 kilograms of lead, 1701 kilograms of zinc and 108 kilograms of copper from 1168 tonnes.
