The Mark Murray (former Green Mountain (L.96) crown grant) occurrence is located on the Sing Main Road, west of Handy Creek at an elevation of approximately 400 metres.

The area is underlain by Upper Triassic Quatsino Formation (Vancouver Group) limestone in contact with andesite of the Lower Jurassic Bonanza Group. The strata is intruded by diorite of the Early to Middle Jurassic Island Plutonic Suite. The intrusive has altered the limestone to masses of garnet and epidote, while the andesite is intensely fractured and metamorphosed, containing bunches and stringers of garnet, epidote and tremolite.

Locally, a weakly foliated iron-copper skarn, oriented at 60 degrees strike and 30 degrees dip to the south east, is exposed over 2 by 2 metres and is least 20 centimetres thick. This is located 1 to 2 metres west of a diorite intrusive contact, striking 150 degrees and dipping vertically. The skarn zone contains chalcedonic quartz and garnet with sulphide mineralization of magnetite, chalcopyrite, pyrrhotite and pyrite. In 2007, two select outcrop grab samples, 364601 and 364651, assayed 4.49 and 1.91 per cent copper, 0.046 and 0.259 per cent zinc, 14.9 and 4.1 grams per tonne silver and 36.3 and 28.5 per cent iron, respectively (Assessment Report 29252). In 2010, a select grab sample (17333) assayed 4.64 per cent copper, 31.8 per cent iron and 10.6 grams per tonne silver (Assessment Report 31708).

A former shaft exposes another skarn zone, approximately 100 metres to the east. The zone is 0.2 metre wide and contains epidote-chlorite-actinolite-garnet alteration with chalcopyrite, pyrite and magnetite hosted by basalt and limestone. In 2009, a sample assayed 7.05 per cent copper, 41.2 per cent iron and 25.3 grams per tonne silver (Assessment Report 31248).

In 2007 through 2013, Nahminto Resources completed a program of prospecting, geological mapping, geochemical sampling, a ground magnetometer survey and airborne geophysical surveys on the area as the TJM claims, part of the Nahmint property.
