Kairos Gold Inc. (TSXV: KIRO) has released assay results from the first two drill holes of its Phase Three exploration program at the Oro Brillante project in Chile. Hole OB-26-02 returned multiple gold-bearing intervals alongside elevated silver and copper values, including a 130.5-metre interval averaging 0.43% copper. The polymetallic character of these results adds a new dimension to what has primarily been a gold-focused project, and investors may be watching how the copper intersections influence the company's evolving geological model.

Key Points

  • Kairos Gold Inc. (TSXV: KIRO) is a Calgary-based mineral explorer with three projects in Chile totalling 17,201 hectares.
  • Phase Three assay results from Hole OB-26-02 returned gold, silver, and copper mineralisation across multiple intervals at the Oro Brillante project.
  • A 130.5-metre interval grading 0.43% copper was highlighted, including a 12.6-metre section grading 1.53% copper; Hole OB-26-01 did not return significant assay results.
  • Approximately 330 samples from Holes 3, 4, and 5 were dispatched to Santiago on September 25, 2026, with additional results to be reported as available.

OB-26-02 Assay Highlights Across Gold and Copper Intervals

Hole OB-26-02 delivered several notable intersections. Highlights include 10 metres grading 1.06 g/t gold and 24.20 g/t silver from 12 to 22 metres, a 20-metre interval grading 0.96 g/t gold from 135 to 155 metres, and a 2-metre high-grade section returning 5.28 g/t gold from 115 to 117 metres. A 14-metre interval from 109 to 123 metres graded 0.94 g/t gold. The release states that all reported interval lengths are downhole lengths, and samples were analysed by 3A Analytical in Santiago using fire assay for gold and ICP-AES for silver and multi-element work.

Copper Mineralisation Adds Polymetallic Dimension to Oro Brillante System

The copper results from OB-26-02 are described in the release as a particularly encouraging outcome. The 130.5-metre interval averaging 0.43% copper, including a 12.6-metre section grading 1.53% copper, suggests that copper may play a more prominent role within the broader system than previously understood. The disclosure notes mineralised core fragments displaying chalcopyrite, bornite, and minor chalcocite from a copper-enriched zone transitioning toward deeper primary mineralisation, offering insight into potential metal zonation and hydrothermal controls at depth.

Hole OB-26-01 and the Broader Phase Three Dataset

While Hole OB-26-01 did not return significant assay results warranting inclusion among the company's principal highlights, the release states it provided important geological information on rock types, alteration patterns, and structural features. Kairos Gold notes this data remains a meaningful component of the Phase Three dataset. Phase Three follows ten diamond drill holes completed across Phases One and Two, which totalled 3,003.8 metres. Core logging, cutting, and sampling are continuing for Holes 6 through 11, with samples to be submitted in batches of two to three holes.
