Aug 15, 2018 (A Wilson) - The Terminus Zone occurs approximately 400-500 m stratigraphically above the Dundeal Ni deposit and displays textural characteristics similar to other Archean volcanogenic massive sulphide deposits. The sulphides are located in several graphitic hyaloclastite horizons between komatiite flows.

Aug 15, 2018 (A Wilson) - The initial drill hole completed by Falconbridge in 1999 returned an assay of 7.53% Zn and 1.37% Cu over 10 m. This intersection also returned an assay of 0.1% Pb, 1.1 ppm Au and 29.1 ppm Ag. The assay also returned significant gold, silver and selenium contents. The sulphides appear to occur as small lenses within the komatiite sequence that are up to 10 m in thickness, but of limited spatial extent. The mineralization occurs as disseminated, semi-massive and massive sulphides that exhibit a zonation with a Cu-rich base and a Zn-rich periphery (Davis, 1997).
