Star Copper Expands Existing Footprint of Star Project and Confirms Broad Mineralized System

THINGS TO KNOW 22.07.2025

VANCOUVER, BC / ACCESS Newswire / July 22, 2025 / Star Copper Corp. (CSE:STCU)(OTCQX:STCUF)(FWB:SOP) ("Star Copper" or the "Company"), a critical minerals exploration and development company announced today that concurrent to its summer drill program it has successfully completed an important field program at the Copper Creek target area located within the Company's wholly owned Star Project in northwestern British Columbia's golden triangle.

Text size:

In addition to the Star Main discovery, historical exploration now confirmed by the Company, has identified at least four additional "fingers" surrounding the Star Main discovery that may each hold significant and complementary discoveries of their own. If successful, the current campaign could prove the entire Star Project as an expansive, mineralized system and deposit.

Located approximately two kilometers (2km) to the southeast of the current drilling campaign, Copper Creek's geological setting, structural complexity, and documented copper grades suggest it may represent a southeastern extension of a broad mineralized system that extends from the Main Zone. Copper Creek holds potential to evolve into a satellite or connecting zone within a larger, continuous copper-bearing trend across the property. The fully funded campaign currently underway is focused on expanding the existing deposit at the Star Project by exploring the historically identified and known mineralization events at Star Main, Copper Creek, Star North, Star East and additional related target locations (See Figure 1).

Highlights

The Copper Creek target was the initial (1937) discovery on the property.

Centered on an impressive gossan in the walls of Copper Creek characterized by extensive malachite and azurite staining.
Copper and gold soil anomalies cover the target location over a 1000m x 550m area.
Geophysical anomalies have been discovered and are still open to the north, south and east.
Six historical drill holes, with incomplete drill logs, include significant copper and minor precious metal values.
An example intercept from the early drilling at Copper Creek includes 43.58m @ 0.49% Cu from 8.53 to 52.12m in DDH G-2-70. (341104 mE, 6456326mN UTM 9N, 000/-80 - Property File 800226)
Recent field work has validated historical exploration records and establishes a reliable geospatial foundation for future exploration.

Copper Creek is a historically explored copper prospect first identified in the 1930s, with significant exploration conducted in the 1970s by Skyline Explorations and United Cambridge Mines. Historical drilling intersected compelling copper and gold mineralization, including 35.5 metres grading 0.485% copper in hole G-2 and localized gold values of up to 4.5 g/t over 1.37 metres (G-2-70, 8.54 - 9.91m). Mineralization is characterized by disseminated and fracture-controlled chalcopyrite and pyrite hosted in brecciated volcanic rocks and skarn zones, spatially associated with intense chlorite-epidote alteration.

Star Copper recently executed a field program at Copper Creek which was led by two geologists and one field assistant. The objectives of the program were to verify the locations of historical drill collars (holes G-1 through G-6), conduct detailed geological mapping, and collect representative rock samples. The team successfully located all historical collar sites, confirmed by the presence of vintage drill equipment, and collected 13 rock samples from mineralized outcrops and altered zones (See Figure 2). These findings validate historical exploration records and establish a reliable geospatial foundation for future exploration.

"We are very encouraged by the results of this recent field work, which confirm historical copper mineralization and provides important geological context for ongoing targeting," said Darryl Jones, CEO of Star Copper. "With Copper Creek located just two kilometres southeast of our current drilling operations at the Main Zone, we see strong potential for this target to evolve into a complementary satellite zone or becoming part of a larger, continuous mineralized system."

Copper Creek's favorable geological setting, structural complexity, and proximity to current exploration activities make it a high-priority target for future work. The Company believes that Copper Creek may represent the southeastern extent of a broader mineralized trend that extends northwest toward and the Main Zone, offering significant upside for resource expansion (See Figure 3).
