CARMACKS PROJECT

HIGHLIGHTS:

• Consolidation of 176 square kilometre, brownfields property in southern portion of high-grade Minto Copper District in Canada's Yukon Territory
• On-trend with the high-grade Minto Cu-Au-Ag Mine to the north with copper mineralization contained in similar foliated to gneissic material
• Current 43-101 mineral resource estimate consisting of 23.76 million tonnes (oxide and sulfide combined) grading 0.85% Cu, 0.31 g/t Au, 3.14 g/t Ag, containing (446 Mlbs Cu, 237,000 ozs Au and 2.4M ozs Ag)
• Significant expansion of existing 43-101 mineral resource estimate expected based on 2021 drilling
• Large historic database including drilling, trenching, geophysics and geochemical sampling
• ~13,000 meter drill program launched early May 2021
• Multiple drill-ready exploration areas with two at step-out drilling stage from initial discovery and six large scale, early-stage exploration targets
• Close to infrastructure including grid power, all-season roads and international highways leading to existing deep-sea ports equipped for concentrate shipping and handling
• Mining-friendly jurisdiction with a long history of exploration / mine development

OVERVIEW:

In November 2020, Granite Creek Copper completed its acquisition of Copper North Mining Corp, combining its Stu Cu-Au Project with the PEA-stage Carmacks Cu-Au-Ag project, thereby consolidating the southern half of the productive and highly prospective Minto Copper Belt in Canada’s Yukon Territory. This 100%-owned, newly constituted, 176-square-kilometer Carmacks property is on trend with Minto Exploration’s high-grade Minto Copper-Gold Mine to the north and its excellent access to infrastructure includes the paved Yukon Highway 2 within 60 km as well as grid power within 12 km.

Granite Creek has emerged as a significant new copper-focused exploration and development company with an existing NI 43-101 mineral resource estimate and exceptional expansion potential. In May 2021, the Company embarked on its largest drill program to date, a three-phase campaign with results expected to form the basis of signifcant update to current resources and economics.Minto Copper Belt

The Minto Copper Belt is a 180-kilometer-long by 60-kilometer-wide belt of intrusion-related, high-grade Cu-Au-Ag deposits within the Dawson Range in the central Yukon Territory of Canada. The District is host to the operating Minto Mine and Granite Creek’s Carmacks Project. At Carmacks, copper mineralization is contained in foliated to gneissic material, generally similar to the Minto mine.
