The Pink Rose occurrence is situated on the western side of Klekane inlet off Graham reach, at an elevation of 560 metres.

The property was formerly known as the Bolton group and was initially located in 1911. During 1916-1917 the claims were under option to The Granby Consolidated Mining, Smelting and Power Company Limited. After considerable development work Granby relinquished their option. In l918, J. Leedy of Seattle, did some prospecting on the group. In 1922 A. McLeod and Associates purchased the property. At that time the group consisted of four claims (Copper-Cliff, New Crown, Lily, and Pink Rose) but as the development work continued, the group was expanded and in 1926 consisted of eight claims: Copper-Cliff, New Crown, Bella, Key, Pink Rose, Last Chance, Last Chance No. 2 and Bonanza. During the period 1922-1930 the main development work included stripping) trenching along veins and the driving of an adit for 20 metres through granite and schists, and then drifting 9 metres on the vein. During 1996-2005 the area was prospected and sampled by J.T. Lawrence.

The area is underlain by the north western end of a north westerly trending keel of metasedimentary and metavolcanic rocks (Alexander Terrane) that extend south easterly along the shores of Princess Royal Channel. These comprise predominantly fine to medium-grained metagreywackes containing minor amounts of what may have originally been either tuffaceous or pelitic beds. The Alexander Terrane rocks have been intruded and surrounded by granodiorite rocks of the Cretaceous Butedale Pluton (Ecstall Plutonic Suite). Regional metamorphism progressed to biotite-garnet grade in the middle amphibolite facies throughout the Alexander terrane rocks.

Chalcocite and bornite occur in altered limestone interbedded with chlorite schist within granodiorite of the Butedale Pluton. The metasediments strike 120 degrees and dip vertically and contain the altered minerals garnet and epidote. The mineralization is traced for 30 metres along strike, 18 metres vertical distance, and 0.5 metres width. Values in gold and silver were reported.

To the east, about 100 metres below the original showing, is a quartz vein up to 2 metres wide and 150 metres long containing chalcopyrite.

In 2005, a composite chip sample (K 7-1) of material with visible bornite-chalcocite mineralization, taken from around the caved portal and from what remained of the main adit dump, returned 0.939 per cent copper. A composite chip sample (K 8-1) taken across the 1.2 metre wide, malachite-stained face of the upper adit returned 0.484 per cent copper. Two other samples, K 8-3 and K 8-4, were taken from around the small pit above the upper adit. Sample K 8-3 was a composite chip sample of visibly mineralized material and sample K 8-4 was a selected high-grade bornite sample. Those samples contained 0.693 and 11.650 per cent copper, respectively (Assessment Report 28298).
