METALS CREEK EXTENDS COPPER MINERALIZATION AT THE TILLEX COPPER PROJECT

Metals Creek Resources Corp. has released initial results from the recently completed (see news release dated March 20, 2025) diamond drilling program at the Tillex copper project, located in Currie township, 65 kilometres east of Timmins, Ont., and approximately 45 kilometres from the Kidd Creek Met site.

This program entailed seven diamond drill holes totalling 909.5 metres 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 new release dated Feb. 27, 2025) which returned a downhole intercept of 7.90 metres of 1.27 per cent copper and 3.42 grams per tonne silver in an effort to determine orientation of prospective mineralized stratigraphy.

TX25-029 extended copper mineralization to the north (Section 180N) and is located one section north of hole TX24-026, which intersected two zones of mineralization (see news release dated March 20, 2025) including 1.00 per cent copper and 2.19 grams per tonne silver over 21.00 metres and 0.94 per cent copper and 4.51 grams per tonne silver over 9.00 metres. Hole TX25-029 collared in diabase diking, eventually intersecting mineralized argillites at a downhole depth of 72 metres and continuing through weakly mineralized feldspar porphyry. This hole returned a downhole intercept of 0.55 per cent copper and 1.97 grams per tonne silver over 9.09 metres. Mineralization consisted of disseminated to fine stringers of chalcopyrite in both the argillites and feldspar porphyry becoming finer downhole. Trace to 2 per cent finely disseminated to stringer galena and local disseminations of sphalerite are also present with associated 1 per cent to 5 per cent disseminated to blebby pyrite. Mineralization is hosted primarily within altered graphitic argillite, silicified feldspar porphyry and wackes.

TX25-030 returned no significant assays. This hole collared in a diabase dike and remained in this unit for the majority of the hole. This hole was an undercut of hole TX24-026 (see news release dated March 20, 2025).

TX25-031 was engineered to fill in a large gap in historic drilling, in which significant portions of these historic holes were unsampled due to the very-fine-grained nature of the copper mineralization. Prospective stratigraphy, including the feldspar porphyries, was unsampled, thus requiring additional drilling to upgrade the current geological model. This hole returned two intercepts, with the upper zone drilling a downhole intercept of 46.40 metres at 1.66 per cent copper and 3.67 grams per tonne silver. Included in this intersection is a higher-grade interval of 3.40 per cent copper and 5.64 grams per tonne silver over 19.20 metres. Mineralization consists primarily of locally very fine, pervasive disseminated chalcopyrite, crosscutting chalcopyrite stringers, as well as nodular chalcopyrite to chalcopyrite veins and 1 per cent to 3 per cent disseminated pyrite within locally strongly folded and clay-altered graphitic argillites. This upper zone also included mineralized feldspar porphyry with stringer to blebby chalcopyrite with abundant quartz stringers. A second zone (lower zone) of mineralization was also intersected similar to that of hole TX24-026. This lower footwall zone of disseminated pyrite and chalcopyrite is hosted within predominantly finer-grained wackes and graphitic argillites and returned a downhole intercept of 1.03 per cent copper and 3.41 grams per tonne silver over 15.80 metres. Sphalerite and galena are also present and illustrate a strong spatial association with pyrite mineralization. Assays are still outstanding for both lead and zinc and will be released once overlimits are received and compiled. Pyrite mineralization appears to be increasing to the north, as does the presence of galena and sphalerite, as illustrated with holes TX25-029 and TX25-031.

Management is highly encouraged with this latest round of drilling with the identification of prospective areas of no sampling from historic drilling that are returning high-grade copper and silver values as well as new lead zinc mineralization discovered in hole TX25-029 and TX25-031.

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

Michael MacIsaac, PGeo, vice-president, exploration, for the corporation and a qualified person as defined in National Instrument 43-101, is responsible for this release and supervised the preparation of the information forming the basis for this release.

All samples were sent to Activation Laboratories. Samples utilized aqua regia digestion with analysis performed by ICP. Overlimits were performed by ICP-OES. As part of the corporation's quality assurance/quality control protocol, approximately 10 per cent 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.
