The Gold Plate showing occurs in Upper Triassic Nicola Group volcanic rocks near the contact with the Late Triassic-Early Jurassic Iron Mask batholith to the east. The showings consist of narrow veins and stringers of quartz and calcite mineralized with galena, tetrahedrite, azurite and malachite. The veins and stringers cut andesitic flows, tuffs and breccias of the Nicola Group. The flows and breccias are massive, but attitudes in tuff beds indicate a strike of 330 degrees with 67 degree southwest dips. Several cuts, a pit and an incline shaft have explored the veins which strike northwesterly and dip steeply southwest. The veins and stringers are from 2 to 25 centimetres wide and are anastomosing.

The original Gold Plate claim was owned by E.S. Batchelor of Kamloops, but is believed to have lapsed (ca. early 1940s). In 1972, Rolling Hills Copper Mines Ltd. conducted geological mapping and a ground magnetometer survey on the Pam and Fox claims covering the showing.
