Upside Gold Corp. Delivers First Exploration Update for the Kena Gold-Copper Property

Executive Summary

• Upside Gold completed a July 2025 surface rock geochemical program on its 10,115‑ha Kena Gold‑Copper Property, identifying 22 priority diamond‑drill targets inside and outside the historic resource.
• High‑grade assays were returned, including up to 26.1 g/t Au, 179 g/t Ag and 1.68 % Cu, confirming a large multi‑zone mineralized system that extends east and south of the known lode gold body.
• The program collected 141 grab samples; results support follow‑up diamond drilling to test extensions at depth, laterally along strike, and into newly accessible zones (Euphrates, Cat, Shaft, Dighem, Princess, Kena Copper Zone, South Gold Zone).

Key Details

• Program Scope: 141 rock geochemical grab samples collected across historic showings, new traverses, and road‑cut exposures; sampling focused on known high‑grade zones and previously untested areas.
• Assay Highlights (selected):
• Euphrates showing: 26.1 g/t Au, 179 g/t Ag, 297 ppm Cu (sample 4339375) – highest gold grade reported.
• Princess showing: 5.41 g/t Au, 0.9 g/t Ag, 61 ppm Cu (sample 4339310).
• Shaft Au‑Cu showing (east of historic resource): 5.41 g/t Au, 4.4 g/t Ag, 10,500 ppm Cu (sample 4339320).
• Cat Au‑Cu showing: 1.12 g/t Au, 3.4 g/t Ag, 6,530 ppm Cu (sample 4339360).
• Average Results for Euphrates Area (9 samples): 8.61 g/t Au and 31.6 g/t Ag; range from 0.022 g/t Au to 26.1 g/t Au, 0.5 g/t Ag to 179 g/t Ag.
• Target Identification: 22 drill‑hole collar sites prioritized for follow‑up diamond drilling based on assay highs, structural controls (Kena Deformation Zone), IP chargeability anomalies, and coincident geochemical signatures.
• Geophysical Context: Strong low‑magnetic intensity signature associated with the Kena Deformation Zone; two‑pronged IP chargeability anomaly (1.8 × 0.6 km) aligns with Cu‑Au‑Ag showings.
• Historical Resource Reference: Historic NI 43‑101 estimate (May 2021) – 32.1 M t @ 0.544 g/t Au (Indicated) and 177.5 M t @ 0.486 g/t Au (Inferred). Upside Gold has not re‑qualified this as a current resource; further drilling required.
• QA/QC: Samples shipped to ALS Canada Ltd.; blind standards, blanks, and duplicates included; analyses performed by four‑acid digestion ICP‑AES for Au and 34 multi‑element suite.
• Next Steps: Detailed diamond‑drill program targeting the identified 22 collars to test lateral extensions, depth potential, and newly accessible copper‑gold porphyry bodies (Euphrates, Cat/Shaft/Princess, Kena Copper Zone, South Gold Zone).

Notable Quotes

“This initial field program represents an important step in advancing our understanding of the Kena Gold‑Copper Property,” said Sophy Cesar, CEO of Upside Gold Corp. “The results support our exploration model and help define priority targets for follow‑up diamond drilling beyond the existing lode gold bearing body.”
