STAR DIAMOND CORPORATION

ACQUIRES 100 PERCENT INTEREST IN BUFFALO HILLS DIAMOND PROJECT

SASKATOON, Saskatchewan, July 15, 2024 – Star Diamond Corporation (“Star Diamond” or the “Corporation”) is

pleased to announce that , pursuant to a definitive agreement date d July 11, 2024, the Corporation has acquired

the interest of Canterra Minerals Corporation (“Canterra”) (CTM: TSX.V) in the Buffalo Hills Diamond Project (the

“Project”) in north central Alberta Canada. Upon closing Star Diamond will hold 100% of the Project.

As consideration for Canterra’s 50% interest in the Project, the Corporation will issue 17,500,000 common shares

(the “Consideration Shares”) representing an implied purchase price of $1.1 million. One half of the Consideration

Shares are subject to a 12 -month lock -up arrangement. In addition to the Consideration Shares , Canterra was

granted a 1% royalty interest in the Project. Completion of this acquisition is subject to certain customary closing

conditions, including approval of the TSX. All of the Consideration Shares are subject to a customary four month

hold period.

Ewan Mason, President and CEO of Star Diamond Corporation said: “We are excited to gain control of the 50% of

Buffalo Hills Diamond Project we did not own. In early 2023, we dusted off the file on this property and conducted

an examination of the existing diamond parcel that was collected from a bulk sample previously taken in 2010. Our

diamond specialist thoroughly analyzed the diamonds and we were astonished to find not only anomalous levels of

Type IIa diamonds in the sample but also a presence of fancy yellow diamonds (K6 yellow diamonds) with elevated

modelled diamond prices. It became clear to us that further work needed to be done and with a number of pipes

at surface we believe that a larger bulk sample should be taken to determine how many of the 38 pipes on the

property may be economic. Our plan would be to eventually extract a bulk sample and ship it to Fort à la Corne and

run the sample through our on-site bulk sample plant.”

Chris Pennimpede, President and CEO of Canterra Minerals Corporation said: “We are confident that Star Diamond

will be able to maximize the value of the Buffalo Hills Diamond Project as a dedicated diamond explorer with

complementary assets in the region. Canterra is now focused on advanced stage copper and gold exploration in the

central Newfoundland Mining District and looks forward to maintaining its exposure to the Project as a Star

Diamond shareholder. We will be watching developments with much interest as our equity participation in Star

Diamond provides our company with exposure to future success.”
