SASKATOON - Star Diamond Corporation ('Star Diamond' or the 'Corporation') today announced that a total of 3,423 diamonds weighing 199.36 carats have been recovered to date from the tenth (19FALCT006) bulk sample trench excavated on the Star Kimberlite by Rio Tinto Exploration Canada Inc. ('Rio Tinto Canada') in 2019.

'We are pleased by the recovery of four larger 8.59, 6.52 (Type IIa), 5.09, 4.04 carat diamonds from Rio Tinto Canada's tenth trench,' said Ken MacNeill, President and CEO of Star Diamond. 'The initial results from the ten reported trenches continue to validate the grades outlined in our Preliminary Economic Analysis that was based upon Star Diamond's own prior underground bulk sampling and large diameter drilling programs. The recovery of larger diamonds from Rio Tinto Canada's bulk sample program, including larger Type IIa diamonds, also continues to strengthen our expectation for recovery of large, high value diamonds in a future producing diamond mine.'

Senior Technical Advisor, George Read, states: 'The tenth trench (19FALCT006) has produced a total of 14 diamonds greater than 1 carat namely: 8.59, 6.52, 5.09, 4.04, 2.89, 2.10, 1.99, 1.65, 1.45, 1.44, 1.22, 1.21, 1.20 and 1.08 carats, respectively, and all were recovered from Early Joli Fou ('EJF') kimberlite. The EJF is the dominant kimberlite unit within the Project in terms of ore volume and diamond grade.'
