Feb 23, 2021 (Therese Pettigrew) - The property is underlain by andesitic flows and to a lesser extent basaltic flows. Foliation within the flows strikes from 65 to 85 degrees and dips steeply to the north. Quartz veins up to 25.4 cm (10 inches) have been observed within the andesite. No significant mineralization has been noted within the quartz veins or in smaller quartz-carbonate veinlets. In places, the andesite is sheared and/or silicified and mineralized to some degree. Bands of iron formation are associated with the metavolcanics. A lensoid body of diorite cuts the metavolcanics and iron formation. The diorite is medium- to coarse-grained with subhedral feldspar and amphibole phenocrysts up to 0.13 cm (0.05 inches) in size (Speed and Craig, 1992).

Feb 23, 2021 (Therese Pettigrew) - A total of 283 reverse-circulation holes were drilled on the occurrence by Legion Resource in 1987. No gold assays were reported, but a number of anomalous arsenic values were recorded with a high of 571 ppm As. Exposure in 2002 consisted of mafic massive and pillowed mafic flows and medium-grained gabbro. Moderate, pervasive carbonate alteration is present in all the rock types. Weak to intense mineralization in the form of disseminated pyrite is present in the mafic metavolcanic rocks. A sample from the massive flow unit assayed 0.08 ounce gold per ton and 158 ppm Cu. Samples returned up to 2.16 g/t Au over 1.16 m and 1.91 g/t Au over 1.5 m (Hart et al., 2002). The main discovery of the Anglo-Beardmore property was a quartz vein 3 to 4.5 m (10 to 15 feet) wide which strikes N 60 degrees E and dips steeply SE. The quartz was white, barren-looking with sparse mineralization of pyrite and arsenopyrite. Samples taken by Burton (1936) assayed 0.03 to 0.13 ounce Au per ton. Maylor Hayne reported grab samples up to 0.22 ounce Au per ton in a 1937 report. Christianson (1947) reported a grab sample of 0.63 oz/t Au and a shallow diamond drill hole on a 5.5 m (18 feet) wide section which ran 0. 04 ounce Au per ton (Speed and Craig, 1992).
