The Nan showing is located west of Green Creek, approximately 2.8 kilometres east of the Flight 5 showing (092F 563).

The area is underlain by volcanics rocks of the Upper Devonian McLaughlin Ridge Formation (Sicker Group). These have been intruded, to the west, by a large body of Jurassic Island Intrusives and are locally overlain by Nanaimo Group Sediments.

Locally, malachite and trace chalcopyrite on fractures occur in agglomeratic basalts of the Upper Devonian McLaughlin Ridge Formation (Sicker Group). A 20 centimetre chip sample assayed 0.51 per cent copper (Assessment Report 16592).

In 1987 and 1988, Roap Resources completed programs of soil, rock, and silt geochemical surveys, geological mapping, geophysical surveys and a seven hole diamond drill program, totalling 1002.0 metres on the Rush (092F 446), Sicker (092F 467) and Nan claims. In 1991, Goldbank Ventures Ltd. Completed a program of prospecting, geological mapping and geochemical sampling on the Green Group. In 1996, E.W.
