Nov 21, 2014 (K R Kettles) - Intermediate and felsic tuffs are interlayered with mafic lavas. The pyroclastic rocks are sheared parallel to bedding and contain auriferous quartz stringers and veins up to 45 cm wide. The wallrocks contain much sulphide, and are altered to actinolite and carbonate adjacent to the veins.

Sep 30, 2020 (K R Kettles) - The felsic to intermediate pyroclastics contain a shear zone which can be traced for 900 m. Within the shear zone are auriferous quartz stringers and veins containing gold, silver, with minor chalcopyrite, sphalerite, galena, pyrite and marcasite. The wall rock contains significant sulphides as well. Assays from samples in the southeast corner of KRL 1894 returned assays of 0.26 opt Au/.55m, 0.04 opt Au/.61 m, 0.06 opt Au/.46 m, 0.21 opt Au/.82 m, 0.29 opt Au/.3 m, 0.18 opt Au/1.52 m, 0.35 opt Au/1.01 m, 0.07 opt Au/.82 m, 0.11 opt Au/.43 m, and 0.12 opt Au/.46 m. In 1963 a sample assayed 0.42 opt Au/.61 m and samples assayed up to 2.7 opt Ag/.61 m. 2009 Multiple grab samples taken - highest 8.34 ppm Au and 12,350 ppm Cu (Assessment report 20000006127).
Sep 30, 2020 (Therese Pettigrew) - DDH RL08-01 returned up to 4.28 g/t Au and 9780 ppm Zn over 0.3 m and 3.72 g/t Au over 0.6 m from a basalt flow with major pyrite, minor sphalerite and pyrrhotite, and trace chalcopyrite. Sulphides occur in layers or quartz-carbonate veins (Assessment report 20000004122).
Dec 07, 2005 (K R Kettles) - The wallrocks contain significant sulphides and are altered to actinolite and carbonate adjacent to the veins.
