The Cholla is part of the Meridian property (082KNW064). The Cholla claim group on Lexington Mountain adjoins the west margin of the Eva (082KNW066) and Criterion-Oyster (082KNW065) groups and extends beyond Pool Creek to Camborne.

The country rocks are phyllites of the Broadview Formation of the Lower Paleozoic Lardeau Group.

The quartz veins on these claims are all gold bearing, however, there is little development other than two short adits, 38 metres apart, driven on the Cholla vein. The Cholla is a well defined vertical, north-trending quartz vein cutting phyllites that strike 110 degrees and dip 85 degrees northerly. A sample from the upper adit, 1.5 metres across the face, assayed 18.5 grams per tonne gold and 13.7 grams per tonne silver. A manganese enriched, pyritic sample from the same general area assayed 41 grams per tonne gold and trace silver. A sample from the lower adit, one metre across the vein containing many fragments of phyllite in the quartz, assayed 13.7 grams per tonne gold (Annual Report 1914, page 256).

In 1975, Doug Hopper evaluated the mineral content of the tailings pond on the Treadwell and Cam claims. Nine auger holes, for a total of 31.7 metres averaged 1.3 grams per tonne gold and 58.3 grams per tonne silver (Assessment Report 5690). The pond measures about 200 by 50 metres. Metallurgical tests were run in 1976.
