The Chapman/Wort adit is located near a small on the eastern side of the Skagit River, approximately 1 kilometre south of its confluence with Snass Creek.

The area is underlain by Permian-Jurassic Hozameen Complex cherts and argillites and minor younger diorite intrusions.

Locally, narrow silver- and copper-rich veins are reported in several places. A 1960’s diamond drilling effort in a small silicified and pyrite-rich outcrop, 150 metres north of the adit, had intersected several feet of sulphides at approximately 80 feet depth, with only sludge recovered.

In 1989, two samples (JW1 and JAC-S1-03) from a 10-centimetre vein in the adit yielded 393.5 and 355.9 grams per tonne silver, 6.70 and 2.65 per cent copper, 0.29 and 0.89 per cent lead, 0.29 and 1.159 per cent zinc, respectively, and up to 1.4 grams per tonne gold (Assessment Report 19715). Another sample (JAC-S1-04), taken at this time from a 4- centimetre wide quartz vein hosted by cherts, assayed 0.709 per cent copper, 1.674 per cent lead and 318.2 grams per tonne silver (Assessment Report 19715).

During the 1960’s and 1970’s, the area was explored by John Chapman and Jim Wort. Programs of surface prospecting, locating and prospecting of the historical adit and minor diamond drilling were completed during this time. In 1989, 4.1 line-kilometres of combined ground magnetic and electromagnetic surveys were completed on the area as the Skagit property. Minor rock sampling was also completed at this time.
