Metals Creek Returns 1.52% Cu and 8.48 g/t Ag over 28.8m at the Tillex Copper Project

Rhea-AI Summary

Metals Creek Resources Corp. (MCREF) has announced significant drilling results from its Tillex Copper Project in Ontario. Drill hole TX25-032 intercepted 1.52% copper and 8.48 g/t silver over 28.8 meters, including a higher-grade section of 2.61% copper and 14.92 g/t silver over 13.27 meters. The drilling program, completed in March 2025, consisted of seven diamond drill holes totaling 909.5 meters, aimed at extending copper mineralization northward and exploring areas with limited previous drilling. The mineralization was found in feldspar porphyry and graphitic argillite, with chalcopyrite present in various forms. The project is strategically located 65 km east of Timmins and 45 km from the Kidd Creek Met site.

Positive

• Strong copper mineralization with 1.52% Cu over 28.8m including higher grade of 2.61% Cu over 13.27m
• Mineralization appears more consistent than historically thought, especially near contacts
• Strategic location near Kidd Creek Met site (45 km) and Timmins (65 km)
• Successful extension of mineralization with true widths approximately 70-80% of downhole intercept

Negative

• None.

• Mineralized Feldspar Porphyry
• Intercept of 1.52% Cu & 8.48 g/t Ag over 28.8m incl 2.61% Cu & 14.92 g/t Ag over 13.27m

Thunder Bay, Ontario--(Newsfile Corp. - June 5, 2025) - Metals Creek Resources Corp. (TSXV: MEK) (FSE: M1C1) (the "Company" or "Metals Creek") is pleased to announce additional drill results from the recently completed (See News Release: March 20, 2025) diamond drilling program at the Tillex Copper Project located in Currie Township, 65 km east of Timmins, Ontario and approximately 45 km from the Kidd Creek Met site.

This program entailed seven diamond drill holes totaling 909.5 meters (m) in an effort to extend copper mineralization to the north, further define areas of limited to no drilling as well as follow-up on copper mineralization drilled outside the mineralized envelope in the previous drill campaign (See news release February 27, 2025).

TX25-032 was designed to test near surface mineralization as well as the continuity of mineralized feldspar porphyry in an area in which historic drilling did not sample portions of holes due to the very fine grained nature of the copper mineralization, including mineralized feldspar porphyry which contains trace to 3 percent (%) chalcopyrite. This hole collared in mineralized graphitic argillite and returned a down hole intercept of 28.8m (40.5-69.3m) of 1.52% Cu and 8.48g/t Ag. Included in this intersection is a higher grade interval of 2.61% Cu and 14.92g/t Ag over 13.27m (54.03 to 67.3m). Mineralization consists primarily of locally, very fine, pervasive disseminated chalcopyrite, cross-cutting chalcopyrite stringers as well as blebby chalcopyrite. Disseminated pyrite is also present within locally and strongly folded clay altered graphitic argillites. Mineralization within the feldspar porphyry included disseminated to blebby chalcopyrite as well as abundant quartz stringers which also contains minor chalcopyrite. Mineralization within the feldspar porphyry appears to be much more consistent than initially thought historically, especially near the contacts with the altered graphitic argillites.

Note: True widths are approximately 70-80% of downhole intercept

Additional assays will be released once they have been received and compiled.

All samples were sent to Activation Laboratories. Samples utilized aqua regia digestion with analysis performed by ICP. Over limits were performed by ICP-OES. As part of the Corporations QAQC protocol, approximately 10% of the samples submitted for assay were also sent for check assays. Standards and blanks were inserted randomly into the sample shipments as part of the sampling protocol.
