About Star Copper Corp. (CSE: STCU) (OTCQX: STCUF) (FWB: SOP / WKN A416ME)

Star Copper Corp. is a Canadian mineral exploration company focused on the discovery and

advancement of large-scale copper-gold systems in British Columbia. The Company’s flagship Star

Project is located in British Columbia’s prolific Golden Triangle and h osts multiple high-priority

targets and exhibits geological characteristics consistent with significant porphyry copper deposits

(watch our videos: https://starcopper.com/media/). The project hosts multiple copper -gold

porphyry-style targets, including Star Main, Star North, East & West, Copper Creek and

Copperline. Significant exploration including historical drilling has confirmed open mineralization

at depth and in all direct ions. Star Copper’s strategic plans include geological mapping and

geophysical surveys to refine existing targets, diamond drilling programs to test high- priority

zones, environmental baseline studies and permitting groundwork alongside data analysis and

resource modeling to support a future resource estimate prepared in accordance with NI 43 -101.

The Company further plans to advance its Indata Project with follow-up drilling to expand on

previous high- grade copper and gold intercepts, trenching and surface sampling to delineate

mineralized zones, and infrastructure improvements for site accessibility and operations. With a

commitment to sustainable development and value creation, Star Copper aims to position itself to

support surging industrial demand to meet growing global electrification needs.
