Aug 15, 2014 (D Draper) - Keevil MIning drillhole HA69-1 (dipping 80° to southwest; drilled at center of geophysical anomaly) intersected 140ft overburden, 590ft of Paleozoics and then dolomitic carbonatite from 731ft to EOH at 1203ft. Sage categorizes the rock type as magnetite sovite.

Aug 15, 2014 (D Draper) - Drillhole intersected massive (up to 75%) magnetite in core lengths up to 2.4m. Apatite up to 40% observed. Very fine-grained, thinly scattered pyrochlore noted in original drill log. A magnetite-rich sample taken at 860ft returned: 37.8% iron, 450ppm Nb, 60ppm Ti, 30ppm Sc, 15ppm Y and 7ppm Yb.
