Kodiak Copper Reports Surface Mineralization Results from Adit Zone

• Nine reverse circulation holes totalling 850 metres completed at Adit Zone with results from surface
• Hole RC-AXE-25-026 returned 79 metres of 0.69% copper equivalent from surface, ending in 27 metres of 1.62% copper equivalent
• Drilling extends mineralized envelope to 550 metres strike length, remaining open in multiple directions
• Most drill holes ended in mineralization rather than reaching planned depths
• Results will support maiden resource estimate for Adit Zone scheduled for Q4 2025

Kodiak Copper (TSX-V: KDK) is a mineral exploration company with copper porphyry projects in Canada and the United States. The company focuses on historically drilled projects with known mineral discoveries. Kodiak's primary asset is the 100% owned MPD copper-gold porphyry project in south-central British Columbia's Quesnel Terrane.

The MPD project contains seven identified mineralized zones. Kodiak completed a resource estimate for four zones in 2025 and plans to deliver a comprehensive initial resource estimate incorporating all zones by year end. The company is led by founder and Chairman Chris Taylor and operates within Discovery Group under John Robins.

Drilling Results and Zone Extension

The 2025 programme tested near-surface mineralization at the Adit Zone using reverse circulation drilling. Hole RC-AXE-25-026 intersected 0.63% copper, 0.05 g/t gold and 4.13 g/t silver over 78.6 metres from surface. The final 26.8 metres of this hole averaged 1.59% copper, 0.01 g/t gold and 4.29 g/t silver.

Additional holes returned mineralized intersections, including RC-AXE-25-028 which intersected 0.42% copper equivalent over 93 metres. Five holes did not reach their planned depths due to ground conditions. The programme was designed as infill and confirmation drilling using shorter holes to characterize near-surface mineralization.

Current drilling has extended the mineralized envelope at the Adit Zone to approximately 550 metres of strike length. Previous drilling programmes encountered mineralization to depths of 350 metres. The zone remains open in multiple directions, with final results from the 2025 programme expected in late Q3.

Resource Development and Technical Programme

The drill data will support a resource estimate for the Adit Zone as part of the initial mineral resource estimate for the MPD project planned for Q4 2025. The programme focused on short, near-surface holes to test mineralization for resource modelling purposes. Nine holes were completed with most ending in mineralization.

Kodiak previously delivered resource estimates for four mineralized zones at MPD in 2025. The company plans to incorporate results from the remaining three zones, including the Adit Zone, into a comprehensive initial resource estimate by year end. The drilling programme used both diamond and reverse circulation methods across the West, Adit, and South Zones.

Samples are processed at Activation Laboratories Ltd. (Actlabs) in Kamloops, BC for preparation and fire assay, with multi-element analysis completed at their Ancaster, Ontario facility. The company implements quality control protocols including sample blanks, duplicates, and certified reference materials at a rate of one per ten samples.

Geological Setting and System Characteristics

The Adit Zone operates within a diorite porphyry system with supergene enrichment and copper oxide mineralization in the upper 100 metres, transitioning to sulphide mineralization at depth. Local faulting and fracturing near surface contributed to challenging ground conditions during drilling operations.

The Adit Zone forms part of a larger system including the historical South and Mid Zones. This system correlates with a 2.3-kilometre copper-in-soil anomaly and related induced polarization chargeability responses. The zone demonstrates typical porphyry system characteristics with multiple mineralization styles.

The MPD project is located in the Quesnel Terrane, a mining district with producing mines and established infrastructure. Metallurgical testing has determined recovery rates of 82% for copper, 60% for gold and 54% for silver, which are used in copper equivalent calculations along with metal prices of US$4.20/lb copper, US$2,600/oz gold, and US$30/oz silver.

Outlook

Kodiak plans to complete final results from the 2025 drill programme in late Q3 2025. The company will use this data to support the maiden resource estimate for the Adit Zone, forming part of the comprehensive initial mineral resource estimate for the MPD project scheduled for Q4 2025. The Adit Zone remains open for expansion in multiple directions with mineralization extending to depth.
