The Rose Marie past producer is located east of the Kennedy River, approximately 3 kilometres north of its mouth at Kennedy Lake, and 25 kilometres north-northwest of Ucluelet, B.C.

Upper Triassic basalts and andesites of the Karmutsen Formation, Vancouver Group are intruded by quartz diorite to granodiorite of the Jurassic Island Intrusions and Tertiary dacitic dikes. The rocks are cut by northwest trending faults which typically show intense shearing and local sericitization, silicification and pyritization over widths of 0.5 to 2 metres.

Locally, a banded quartz vein strikes 070 degrees and dips about 60 degrees northwest through porphyritic diabase or green andesite. The vein varies in width from 38 to 60 centimetres. The quartz is variably reported to be mineralized with pyrite and one or more other sulphides from among sphalerite, chalcopyrite, arsenopyrite, pyrrhotite and galena.

Over 100 metres of drifting on the vein took place from 1899 to 1900. Nine tonnes of ore treated on site in a 4-stamp mill produced 902 grams of gold and 1,928 grams of silver (Mineral Policy data).

In 2008, Kennedy Lake Syndicate completed a program of prospecting on the area as part of the Kennedy Lake Project. In 2010, Gonzaga Resources completed a program of rock and soil sampling and an induced polarization survey on the area. During 2011 through 2014, Gonzaga Resources Ltd. completed programs of rock and soil sampling on the area, outlining an anomalous gold area approximately 1.5 kilometres south-southwest of the ROSE MARIE occurrence.
