Sceptre covers several gold and base metal showings within the north-south trending PLGB – Prongua Lake Volcanic Belt.
Within the eastern part of the Project, three gold showings about 3,000 metres apart, from north to south (Yak, Fish Dot and Sample 4528), appear related to a significant regional shear zone, possibly associated with the TFZ.
The central Fish Dot gold showing is associated with quartz veins and zones of silicification within both sedimentary and volcanic lithologies, while the northern Yak gold showing is hosted by a gabbroic sill. Each are moderately folded, with significant shearing and silicification; both arsenopyrite and disseminations of pyrite, chalcopyrite and pyrrhotite are present. The Fish Dot Gold Showing is exposed over a 60-metre length and consists of a zone of veining and silicification within metasediments. Highlights of the Sceptre gold showings include:
- Yak Showing is exposed across nine trenches and is hosted by sheared gabbroic rocks. Numerous grab samples from the trenches range from 0.13 grams/tonne (“g/t”) to 6.63 g/t gold;
- Fish Dot Gold Showing - two grab samples from quartz veins: 0.94 g/t and 3.63 g/t gold;
- Fish Dot Gold Showing - two grab samples from quartz veins: 3.31 g/t and 16.06 g/t gold;
- Fish Dot Gold Showing - six channel samples, each 0.5 metres in length, ranging from 1.19 g/t to 7.84 g/t gold;
- Sample 4528 - located near Sceptre's southern property boundary, returned 0.74 g/t gold from a zone of gossanous sulfide mineralization; and
- Wood Lake Gold Showing – located in the western part of the Project near a contact between metavolcanics and metasediments. A zone of silicification associated with a contact unit within the metavolcanics returned up to 3.53 g/t gold.

ALX believes that the gold showings at Sceptre could represent the surface expression of a larger mineralizing system that has been underexplored with modern exploration techniques. Planning is underway for a program of geological mapping and sampling for the summer of 2020.
