Granite Creek Copper Acquires Copper-Nickel-PGM Project in British Columbia, Canada

VANCOUVER, August 24, 2022 - Granite Creek Copper Ltd. (TSXV:GCX | OTCQB:GCXXF) ("Granite Creek" or the "Company") is pleased to announce the acquisition of the Star Cu-Ni-Platinum Group Metal ("PGM") project, located in the Omineca mineral belt of northern British Columbia.

Granite Creek will secure a 100% interest in the Star project, with no underlying royalty or further obligation, for a total consideration of $10,000 CDN and the issuance of 500,000 common shares of the Company to the estate of Ursula Mowat. The issued shares will have a hold period of 4 months plus one day from the date of issuance. The Company anticipates closing the transaction on or about the August 30, 2022, subject to TSX Venture approval.

Tim Johnson, CEO of Granite Creek Copper, stated, "I was saddened to hear of the passing of Ursula Mowat who had been a pioneer in prospecting for platinum group metals and associated nickel and copper mineralisation in the Omineca region of British Columbia. As one of the first geologists to recognize the potential for the native iron-nickel alloy awaruite to be a significant source of low-cost nickel in the Omineca area, she will be remembered for her ground-breaking work in the industry. To be able to acquire the Star project claims and continue the development work to unlock the potential that Ursula obviously saw is an honour. We look forward to completing our initial work on the claims and relaying to investors the potential for both precious and battery metals on the project."

"Although Granite Creek's primary focus remains our flagship Carmacks Copper-Gold-Silver project with the pending updated preliminary economic assessment expected in Q4 2022, the Star project increases our exposure to critical minerals at a time when the Canadian government is incentivizing exploration of listed critical commodities in Canada, as part of a broader push to secure supplies of the minerals in North America for national security and to support the development of carbon free energy sources."

About the Star Project

The Star project is located 190 kilometers northeast of Smithers, BC and is within 5 kilometers of the Omineca Resource Road and powerline that served the Kemess Mine. The 2500-hectare project is underlain by ultramafic rocks that are prospective for copper, nickel, cobalt, PGMs and gold. Previous work identified multiple showings consisting of copper and nickel sulphide mineralisation with accompanying PGM and gold values. The showings are identified within six distinct zones spread over a 12-kilometer strike length including Queen Zone, GL Zone, HB Zone, HC Zone, Libra Zone, and Ridge Zone (see accompanying Figure 1 for Zone locations as well as additional areas identified for follow up).

Highlights of some of the best mineralised copper and nickel sulfide bearing rock sampled by Ms. Mowat from the various are identified below:

• 1.18% Cu, 0.17 g/t Au, 0.11 g/t Pd from the Queen Zone
• 0.78% Cu, 0.25% Ni, 833 ppm Co and 0.27% Cu from the GL Zone.
• 0.09 % Cu, 1.32 g/t Pt and 1.82 g/t Pd from the HB Zone.
• 0.87% Cu, 0.18 % Ni, 0.12 g/t Au, 0.41 g/t Pt and 0.83 g/t Pd from the HC Zone.
• 0.31% Cu Cu from Libra Zone
• 0.30% Cu, 0.28 g/t Pt, 0.25 g/t Pd from the Ridge Zone.
