SEGO RESOURCES DISCOVERS COPPER PORPHYRY WITHIN THE SOUTH GOLD ZONE

Sego Resources Inc. has made a new discovery on the Miner Mountain project.

Sego Resources is pleased to report that a new copper porphyry within the existing South gold zone target has been discovered in recent drilling.

Four drill holes were drilled in the South gold zone, DDH25-66, DDH25-67, DDH25-68 and DDH25-69. Three of the drill holes in the South gold zone had intervals with copper porphyry mineralization, drill holes DDH25-66, DDH25-68 and DDH25-69. Drill hole DDH25-69 contained the most extensive mineralized copper porphyry environment.

The new copper porphyry is hosted in potassic (potassium feldspar) altered microdiorite and monzodiorite to monzonite, and less in volcaniclastic rocks (crystal tuffs and lapilli tuffs to ash tuffs), associated with these intrusions. The potassic (K-feldspar) alteration ranges from patchy to extensive in the mineralized areas. The zones are mineralized with chalcopyrite mostly within and around the areas of potassium feldspar alteration. Between the porphyry-style mineralized segments, the core maintains geology similar to other South gold zone holes. Chalcopyrite was also tested using the Niton XRF analyzer, with assays to follow. Potassium feldspar (K-feldspar) is one of the key alteration minerals in porphyry copper deposits.

Four drill holes were drilled in the South gold zone as per the recommendations of SRK Consulting Canada (see news releases from May 23, 2024, Sept. 24, 2024, and Nov. 12, 2025). The purpose of these drill holes was to infill a gap in the previous South gold zone drilling.

In previous work, Sego had thought that the South gold zone might be near a copper-gold porphyry, but had no indication that it would be observed in these holes.

The new copper porphyry will be followed up with extensive drilling in the next program, given the nature of this discovery.

The samples are prepared for shipping to the lab in Calgary.

Drilling of a deep hole in the Cuba zone continues.
