The Nurse area is underlain by marine sedimentary and volcanic rocks of the Upper Triassic Stuhini Group. Eocene intrusions of the Coast Plutonic Complex are emplaced to the west.

The Nurse occurrence consists of two mineralized quartz veins, an "upper" and "lower", which occur immediately south of the South Unuk Glacier. Teuton Resources reported the country rocks to be composed of sediments, predominantly siliceous siltstone. These rocks are characterized by the development of secondary biotite, quartz and mild propylitic alteration. The lower vein occurs in an andesitic tuff that forms a discrete unit within the sediments. Dyke swarms, composed of monzonite, were observed cutting the sediments (Assessment Report 16910).

The two veins cut across the bedding about 200 metres apart and share the same general attitude. The lower and upper veins are exposed for a distance of 70.0 metres and 100 metres respectively. Mineralization consists of massive galena, sphalerite, pyrite and minor chalcopyrite and bornite.

A high grade sample from the lower vein contained 473 grams per tonne silver, 53.3 per cent lead, 7.80 per cent zinc, 0.16 per cent copper and 0.2 grams per tonne gold (Assessment Report 16910).

A boulder train, approximately 100 metres long, was located downhill from the western trace of the lower quartz vein. A sample from a 1.5 metre quartz boulder containing galena, pyrite and minor chalcopyrite and sphalerite assayed 223.0 grams per tonne silver, 5.2 grams per tonne gold, 3.63 per cent lead, 0.02 per cent zinc and 0.01 per cent copper (Assessment Report 16910).

In 2016 Colorado reported that the actual in-situ veins of the Nurse occurrence are on a steep cliff and could not be accessed. Samples from massive sulphide boulders in the talus slope beneath the veins were sampled and were found to have favorable results from different samples such as 90.6 grams per tonne silver from sample 1630377, 1.78 per cent copper from sample 2640167, 3.29 per cent lead from sample 1630376, and 4.40 per zinc from sample 1630377 (Assessment Report 36656).

Work History

In 1987, Teuton Resources Corp was successful in pinpointing a previously reported sulphide boulder train and two potential sources termed the lower and upper quartz veins. Observed vein dimensions and dimensions implied from the boulders indicated potential for significant tonnage (Assessment Report 16910).

In 1990, the Nurse occurrence was held as the Galena Cliff and Pearson claims by Amphora Resources, who conducted an 87.5 kilometre airborne magnetic and electromagnetic survey over their group, including the area of the Nurse showing (Assessment Report 19995).

In 1991 Teuton Resources Corp completed a small prospecting program on the Galena Cliff and Pearson groups. A total of 14 rock samples were collected from the Galena Cliff Group which contained the Nurse showing but the showing area was not visited (Assessment Report 21313).

In 1992, Homestake Canada Inc held the Duke 1-9 claims in the region and collected 75 rock and 87 silts samples. Several samples are shown on their sample locations map, taken near the Nurse showing on the Duke 9 claim (Assessment Report 22930).

In 2006 and 2007, Hathor Exploration Ltd. completed a 7228.7 line-kilometre airborne geophysical survey on the area as the Gracey claims of the Iskut project. In 2008, Max Minerals Ltd. examined the property.

In 2016, Colorado Resources Ltd. completed a reconnaissance exploration program on their KingPin Property which covered the Nurse and 36 other MINFILE occurrences on the property. Work included the collection of 147 rock chip and grab samples and a total of 129 soil samples.
