SASKATOON, Saskatchewan, January 19, 2021 – Star Diamond Corporation (“Star Diamond” or the “Corporation”) today announced that Rio Tinto Exploration Canada Inc. (“Rio Tinto Canada”) commenced an eight hole geotechnical drilling program on and in proximity to the Orion North Kimberlite in early January 2021.

Star Diamond understands that Earth Drilling Co. Ltd of Regina Saskatchewan was contracted to drill an eight-hole program at four locations, with two holes at each location. The drill rigs being utilized are capable of sonic drilling to obtain representative samples of the glacial overburden and core drilling for the underlying kimberlite or host rock sediments. These rigs can sample to a depth of 220 metres below surface. Two of the drilling locations are situated over the Orion North kimberlite and two drilling locations are just to the south of the Orion North kimberlite. Star Diamond has been advised that the aim of this drilling is to investigate the geotechnical properties of the overburden, kimberlite and host rock sediments., with this information to be used for future open pit design. Parts of the Orion North Kimberlite have shallower overburden (of approximately 95 metres) than both the Star and Orion South Kimberlite.
