The Marion showing is located in one of two percussion drill holes approximately 5.8 kilometres east-southeast of Lytton, south of the Thompson River and at an elevation of 1600 metres.
The area is underlain by Triassic Mount Lytton Complex intrusives comprising granodiorites, quartz diorites and amphibolites. Steeply dipping, southeast-striking shear zones and fractures are extensive.
Dioritic hostrocks have been chlorite altered and intense oxidation and leaching are typical within shear zones. Characteristic alteration minerals are chlorite, hematite, sericite and kaolin. Oxidation minerals include limonite, cuprite and malachite. Shear zones up to 15 metres wide in drill core and traced for 200 metres host quartz veins which carry locally disseminated bornite and malachite. Grains of bornite were visible in sample. Pyrite, chalcopyrite and molybdenite were reported, but not defined in drill logs (Assessment Report 10881).
This claim was explored by surface work by various owners intermittently from the turn of the century. The only known previous work was a diamond drill hole collared in 1968 on a zone of copper-enriched quartz veins by Burlington Mines Limited (Assessment Report 10881). John G. Wells had two percussion holes drilled in the area in 1982 to test a southeast-trending shear zone exposed by a road cut and an intensely altered area exposed by bulldozer work. The cores were examined and logged by R.A. Wells in December of that year.
