K92 Mining Announces Major Expansion of Arakompa AR1 High-Grade Zone and Delineation of Substantial Near-Surface High-Grade Bulk Tonnage Zone

On June 4, 2026, K92 Mining announced the sixth set of drilling results from its Arakompa project, located near the Kainantu gold mine in Papua New Guinea. The 33 new holes (100 total drilled to date) all intersected mineralization, with 40 intercepts grading above 5 g/t gold equivalent (AuEq) and 20 above 10 g/t AuEq. The AR1 high-grade vein was extended to a vertical extent of ~300 m and strike length of ~400 m, starting 100 m from surface, with a weighted average grade of 9.47 g/t AuEq across 4.32 m true width. Notable AR1 hits include 11.90 m at 14.30 g/t AuEq and 10.00 m at 15.21 g/t AuEq. The AR2 vein also returned exceptional grades (e.g., 4.70 m at 41.90 g/t AuEq).

Importantly, the release delineates a large near‑surface high‑grade bulk‑tonnage zone, with wide intervals such as 49.30 m at 1.95 g/t AuEq and 140.10 m at 1.27 g/t AuEq, now confirmed toward surface along a +2 km strike. Another highlight is the start of porphyry vector drilling, with a hole intersecting 1,151.20 m of outer potassic alteration at 0.30 % copper equivalent (CuEq). A second drill rig has been allocated to chase a potential high‑grade potassic core. The company reiterated its plan to deliver a maiden resource estimate for Arakompa in mid‑2026.

The June 4 release is a positive update, but it does not materially change the investment thesis or introduce previously undisclosed information. Since September 2025, K92 has been steadily growing the Arakompa footprint, with each successive drill set expanding the bulk‑tonnage zone and delineating high‑grade veins. The current results confirm continuity and extend the known mineralisation in line with expectations set by earlier exploration updates. The discovery of porphyry‑style alteration at depth is intriguing, yet still very early‑stage – the company is only now targeting the core, with no grade data from that zone. All of this was already embedded in the planned mid‑2026 maiden resource estimate and the 2026 exploration budget of $31–$35 M. The market’s prior reaction to Arakompa news (e.g., September 2025’s fifth set) shows that the deposit’s potential is priced in, and this latest batch adds incremental detail rather than a step‑change. The absence of a new resource number means the news is additive but not transformative.

The only near‑term catalyst – the maiden resource – is still on track, and the release simply confirms that drilling continues to intersect mineralisation. Given the company’s robust production growth, record financials, and strong balance sheet, the Arakompa update supports but does not accelerate the growth narrative. The rating is Routine – Positive.

K92 Mining is a gold‑copper‑silver producer operating the Kainantu Gold Mine in the Eastern Highlands province of Papua New Guinea. The company has transformed from a small underground operation into an emerging mid‑tier producer, with 2025 annual output of 174,134 oz AuEq (16 % year‑over‑year growth). Kainantu comprises multiple high‑grade vein systems – primarily Kora and Judd, with production also from Kora South and Judd South. The company completed a major Stage 3 expansion in late 2025, commissioning a new 1.2 Mtpa process plant under budget and ahead of schedule. This expansion is expected to lift production to the 190–225 koz AuEq range in 2026, with a further Stage 4 expansion targeting >400 koz AuEq by late 2027.

Alongside the producing mine, K92 holds an extensive exploration portfolio. The flagship regional project is Arakompa, a large vein‑bulk tonnage and emerging porphyry target located a few kilometres from the plant. The company is also exploring the Wera greenfields target (a 3.5 × 3.5 km epithermal system), Maniape, Judd North, and other prospects. The maiden resource for Arakompa is expected mid‑2026, and the company aims to demonstrate a multi‑million‑ounce district with long mine life potential.
