SEGO RESOURCES SELECTS DRILL HOLES AND PREPARES FOR DRILLING STRONG CHARGEABILITY ANOMALIES DEEP BELOW THE CUBA AND SOUTH GOLD ZONE MINERALIZATION MID-OCTOBER

Drill sites have been located for Sego Resources Inc.’s fully financed 2,000-metre diamond drill program scheduled to start mid-October, 2026.

The analysis of 3-D inversion of the IP (induced polarization) Volterra diamond array program has defined several deep IP chargeability targets beneath or near known mineralization at both Cuba and the South gold zones (news release dated Sept. 2, 2026).

The proposed diamond drill holes are normally inclined to 55 degrees and are projected to surface. The planned drill holes may vary to steeper inclinations to cross the chargeability anomalies and to explore the copper plus gold potential associated with the chargeability anomalies and near-surface zones of mineralization.

The chargeability highs or anomalies are more than 12 ms (milliseconds) beneath the southern part of the Cuba zone, and measure about 500 metres east-west and up to 200 m north-south. The high strengthens from about 425-metre to 500-metre level plans. This is the maximum depth of the Volterra survey that was completed earlier this year.

The chargeability high at the 300-metre level plan occurs north and deeper than the South gold zone mineralization, and both have similar size and geometry. The proposed hole will cross sporadic copper and gold mineralization noted in previously excavated trenches and is expected to intersect the chargeability at depths well below the South gold zone mineralization to the south.

Cuba zone

Two holes are planned to intersect the large deep (greater than 12 ms) chargeability anomaly.

Hole CG1 is collared in the west and north of the Cuba zone and drilled south toward the chargeability high. The hole will drill beneath several high-grade drill intersections reported earlier (see news releases dated May 25, 2010, March 12, 2012, and Jan. 3, 2018):

DDH 10-19: 0.23 per cent copper and 0.13 gram per tonne gold over 24.4 metres (66.14 m to 90.53 m and end of hole);
DDH 12-21: 0.96 per cent copper and 0.55 g/t gold over 100.4 m (10.06 m to 110.45 m);
DDH 17-29: 0.93 per cent copper and 0.26 g/t gold over 27.0 m (8.0 m to 35.0 m) plus 0.16 per cent copper and 0.51 g/t gold over 21.0 m (77.0 m to 98.0 m).

The hole will be drilled south into the western end of the deep chargeability high at about 440 m and continue within the chargeability high for an estimated total length of more than 690 m to reach below the model chargeability high at 500 m below surface.

Hole C2 will be collared south of the southeastern portion of the Cuba zone drilled toward the northeast to drill the deep chargeability target below the Cuba mineralization. A wide zone of strong albite-sericite-pyrite alteration and potassic alteration assemblages was intersected in DDH 71 at more-than-180-metre depth below surface and may be spatially related to the deeper large chargeability anomaly.

Hole C2 will be drilled well below and beneath several intersections previously reported toward the northeast underneath several long mineralized intersections previously reported (see news releases dated March 12, 2012, and Sept. 17, 2018):

DDH 12-27: 0.23 per cent copper and 0.21 g/t gold over 76.2 m (20.4 m to 96.6 m);
DDH 18-31: 0.06 per cent copper and 0.11 g/t gold over 62.0 m (21.0 m to 83.0 m) and 0.011 per cent copper and 0.07 g/t gold over 99.0 m (122.0 m to 221.0 m);
DDH 18-32: 0.14 per cent copper and 0.15 g/t gold over 129.0 m (14.0 m to 3,143 m);
DDH 18-33: 0.36 per cent copper and 0.07 g/t gold over 45.0 m (14.0 m to 3,143 m).

Hole C2 is expected to intersect the chargeability high at about 600 m or about 500 m vertical below surface.

South gold zone

Hole A is collared northwest of the South gold zone directed southeast toward a medium-depth chargeability high. Based on copper mineralization identified in trench sampling and historic DDH holes dating back to 1963 (several samples greater than 0.1 per cent copper), it is suspected that the chargeability high might be associated with deeper porphyry copper mineralization.

The hole will pass in the vicinity of several mineralized holes previously reported (see news releases dated Aug. 11, 2021, and Jan. 31, 2022):

DDH 21-49: 0.61 g/t gold, 0.41 g/t silver and 0.02 per cent copper over 56.9 m (23.0 m to 79.9 m);
DDH 21-53: 0.16 g/t gold, 0.27 g/t silver and 0.01 per cent copper over 82.2 m (3.1 m to 85.3 m);
DDH 21-56: 0.13 g/t gold, 0.27 g/t silver and 0.01 per cent copper over 53.7 m (5.5 m to 59.2 m);
DDH 21-57: 0.34 g/t gold, 0.35 g/t silver and 0.01 per cent copper over 59.65 m (42.65 m to 102.30 m).

Quality assurance/quality control

Control samples comprising certified reference samples, duplicates and blank samples are systematically inserted into the sample stream and analyzed as part of the company’s quality assurance/quality control protocol for the fall-winter drilling exploration program. The company also regularly sends for check assays to another laboratory as part of the quality assurance and quality control protocol.

About the project

Sego is 100-per-cent owner of the Miner Mountain project, an alkalic copper-gold porphyry exploration project near Princeton, B.C. The Miner Mountain project combines alkalic porphyry copper-gold mineralization in the Cuba zone and the elevated gold with variable copper content mineralization in the Southern gold zone (considered a distal alkalic copper-gold porphyry mineralization).

The property is 2,056 hectares in size and is located 15 kilometres north of the Copper Mountain mine operated by Hudbay Minerals Inc. Sego has a memorandum of understanding with the Upper Similkameen Indian Band on whose traditional territory the Miner Mountain project is situated. Sego has received an award of excellence for its reclamation work at Miner Mountain.

We seek Safe Harbor.
