K92 Mining Announces Major Regional Exploration Update: Significant Expansion of Arakompa Deposit, Discovery of Porphyry-Style Mineralization from Arakompa Southernmost Step-Out, and Substantial 3.5 km by 3.5 km New Mineralized System Discovered at Wera
September 11, 2025
VANCOUVER, British Columbia, Sept. 11, 2025 (GLOBE NEWSWIRE) -- K92 Mining Inc . (“ K92 ” or the “ Company ”) (TSX : KNT; OTCQX : KNTNF) is pleased to announce its fifth set of drilling results consisting of 24 holes for total results of 67 holes released to date from its maiden surface diamond drill program at Arakompa, located approximately 4.5 km from the Kainantu Gold Mine Process Plant in Papua New Guinea. Additionally, K92 is pleased to report initial results from its maiden greenfields exploration program at the Wera prospect, outlining a large 3.5 km by 3.5 km mineralized system located approximately 10 km South-West of the Kora and Judd deposits.
- Drillhole KARDD0065, stepping out approximately 250 metres to the south from the latest results at Arakompa, has discovered significant porphyry-style mineralization recording 690.4 metres at 0.30% Copper Equivalent (“CuEq”) ( 2 ) (0.17 g/t Au, 0.17% Cu, 2 g/t Ag) starting at 297.0 metres, including 395.3 metres at 0.38% CuEq (0.24 g/t Au, 0.20% Cu, 2 g/t Ag) starting at 349.7 metres. The hole was designed with two objectives: (i) to test the strike extension at Arakompa; and (ii) to be the first hole drilled to test a 600 metre by 600 metre copper-in-soil anomaly. Intersected mineralization occurred as disseminated sulphides, with vein-hosted and vein-controlled sulphide mineralization present. The sulphide mineralization is dominantly chalcopyrite, with minor bornite and molybdenite also observed. Porphyry-style B, D, and M-type quartz sulphide veins are also present. The intersection is interpreted to be distal to a porphyry potassic core, bottomed in mineralization, and represents a very significant vector for follow-up drilling, which is underway.

Significant extension of the Arakompa bulk tonnage zone strike extent to the north and the south, with the bulk zone now defined over approximately 1,100 metres and to a vertical depth of 800 metres, increasing 200 metres strike and 150 metres depth from the

press release, respectively. Drill results to date have recorded an average true thickness of 39 metres, highlighting strong, near-surface bulk mining potential (see
Figure 5 – Arakompa Bulk Interpretation Long Section)
. The interpreted bulk zone consists of a thick, intensely altered mineralized halo surrounding the high-grade vein lodes and it remains open in multiple directions.

- Maiden greenfields exploration program initially focused on rock chips and trenching at Wera has defined a large ~3.5 kilometre by ~3.5 kilometre low-sulphidation epithermal gold system located approximately 10 km south-west of the Kora and Judd deposits, with several interpreted mineralized structures and high-grade rock chip samples including 26.30 g/t Au, 25.06 g/t Au, 23.97 g/t Au, 22.06 g/t Au, 19.69 g/t Au, 19.23 g/t Au, 18.40 g/t Au, 18.40 g/t Au, 18.03 g/t Au, 16.05 g/t Au, 13.83 g/t Au, 11.09 g/t Au, 10.88 g/t Au, and 10.21 g/t Au (See Figure 8 Wera Plan Map). Importantly, this area was not accessed or tested by previous owners and lies within the major NNE regional mineralized structural corridor that hosts the Kora, Judd and Arakompa deposits. Drilling is now underway.
