K92 Mining Announces Major Expansion Of Arakompa AR1 High-Grade Zone And Delineation Of Substantial Near-Surface High-Grade Bulk Tonnage Zone
K92 Mining Inc. announced its sixth set of drilling results consisting of 33 holes for a total of 100 holes released to date from its maiden surface diamond drill program at Arakompa, located approximately 4,500 m from the Kainantu Gold Mine Process Plant in Papua New Guinea. All drill holes at Arakompa intersected mineralization, with 40 intersections exceeding 5 g/t AuEq and 20 intersections exceeding 10 g/t AuEq. Multiple high-grade intersections recorded at Arakompa's AR1 Vein, with increased drill density expanding and upgrading the near-surface thick high-grade zone, which is now defined up to approximately 300 m of vertical extent and up to 400 m of strike length, starting at 100 m depth. Surface mapping and multiple high-grade rock chip samples indicate that up-dip from the thick high-grade zone, mineralization extends to surface, making infill drilling the top 100 metres a priority target, in addition to the step-out drill program. Within this zone, the weighted average grade and average true width are 9.47 g/t AuEq and 4.32 m respectively. Highlights include: KARDD0076: 11.90 m at 14.30 g/t AuEq (14.00 g/t Au, 9 g/t Ag, 0.18% Cu), including 1.70 m at 92.43 g/t AuEq (91.55 g/t Au, 44 g/t Ag, 0.35% Cu); KARDD0106: 10.00 m at 15.21 g/t AuEq (15.11 g/t Au, 4 g/t Ag, 0.06% Cu), including 4.00 m at 36.65 g/t AuEq (36.50 g/t Au, 6 g/t Ag, 0.09% Cu); KARDD0100: 16.50 m at 8.06 g/t AuEq (7.53 g/t Au, 8 g/t Ag, 0.43% Cu), including 3.00 m at 18.03 g/t AuEq (17.23 g/t Au, 14 g/t Ag, 0.63% Cu); KARDD0090: 8.60 m at 6.79 g/t AuEq (6.40 g/t Au, 8 g/t Ag, 0.29% Cu); KARDD0094: 7.88 m at 6.63 g/t AuEq (5.60 g/t Au, 22 g/t Ag, 0.77% Cu), including 2.15 m at 13.54 g/t AuEq (12.92 g/t Au, 17 g/t Ag, 0.41% Cu); KARDD0091: 4.00 m at 13.90 g/t AuEq (13.21 g/t Au, 26 g/t Ag, 0.38% Cu), including 1.80 m at 30.35 g/t AuEq (28.84 g/t Au, 57 g/t Ag, 0.83% Cu); KARDD0078: 5.10 m at 6.81 g/t AuEq (6.56 g/t Au, 16 g/t Ag, 0.07% Cu). Multiple high-grade intercepts recorded at Arakompa's AR2 Vein, including: KARDD0084G: 4.70 m at 41.90 g/t AuEq (41.46 g/t Au, 4 g/t Ag, 0.38% Cu); KARDD0104: 6.80 m at 15.21 g/t AuEq (15.11 g/t Au, 6 g/t Ag, 0.04% Cu), including 2.00 m at 49.00 g/t AuEq (48.79 g/t Au, 14 g/t Ag, 0.04% Cu); KARDD0090: 3.40 m at 20.31 g/t AuEq (20.21 g/t Au, 5 g/t Ag, 0.03% Cu), including 0.90 m at 71.63 g/t AuEq (71.40 g/t Au, 16 g/t Ag, 0.04% Cu); KARDD0073: 8.00 m at 6.72 g/t AuEq (5.78 g/t Au, 46 g/t Ag, 0.39% Cu); KARDD0105: 3.60 m at 5.02 g/t AuEq (3.45 g/t Au, 56 g/t Ag, 0.91% Cu); KARDD0091: 1.40 m at 7.51 g/t AuEq (6.12 g/t Au, 55 g/t Ag, 0.73% Cu). Multiple, near-surface, high-grade bulk intersections recorded, expanding a high-grade zone towards surface, previously interpreted as lower grade due to lack of drilling. Highlights include: KARDD0091: 49.30 m at 1.95 g/t AuEq (1.79 g/t Au, 7 g/t Ag, 0.08% Cu); KARDD0106: 140.10 m at 1.27 g/t AuEq (1.21 g/t Au, 2 g/t Ag, 0.03% Cu); Both KARDD0091 and KARDD0106 are located approximately 60 m from previously reported hole 005AD92 which recorded 41.9 m at 2.21 g/t AuEq (2.12 g/t Au, 2 g/t Ag, 0.04% Cu). Thick, high-grade bulk zone expanded in multiple directions, with increased drill density improving confidence in geological continuity and highlighting the potential for grade profile upgrades at Arakompa through both infill and step-out drilling. This area has been a major drilling focus ahead of the Arakompa maiden resource estimate. Additionally, surface sampling indicates that mineralization extends to surface along Arakompa’s known +2 km strike length, highlighting multiple high-priority areas for infill drilling up-dip of high-grade zones defined to date in addition to step-out drilling. Highlights include: KARDD0076: 99.00 m at 2.90 g/t AuEq (2.76 g/t Au, 4 g/t Ag, 0.09% Cu); KARDD0084G: 105.40 m at 2.26 g/t AuEq (2.17 g/t Au, 2 g/t Ag, 0.06% Cu); KARDD0090: 106.50 m at 2.22 g/t AuEq (2.11 g/t Au, 3 g/t Ag, 0.07% Cu); KARDD0078: 70.90 m at 1.01 g/t AuEq (0.89 g/t Au, 4 g/t Ag, 0.07% Cu), and 36.40 m at 1.00 g/t AuEq (0.83 g/t Au, 3 g/t Ag, 0.13% Cu); KARDD0094: 137.35 m at 1.07 g/t AuEq (0.95 g/t Au, 3 g/t Ag, 0.08% Cu); KARDD0104: 163.50 m at 1.02 g/t AuEq (0.97 g/t Au, 2 g/t Ag, 0.03% Cu); KARDD0100: 177.55 m at 1.01 g/t AuEq (0.90 g/t Au, 2 g/t Ag, 0.08% Cu); KARDD0075: 77.20 m at 1.01 g/t AuEq (0.85 g/t Au, 5 g/t Ag, 0.11% Cu); KARDD0086: 43.80 m at 1.01 g/t AuEq (0.88 g/t Au, 3 g/t Ag, 0.10% Cu); KARDD0099: 40.50 m at 1.03 g/t AuEq (0.98 g/t Au, 2 g/t Ag, 0.02% Cu). Porphyry vector drilling advanced following the previously reported KARDD0065 discovery hole, with KARDD0077 completing a ~250 m southern step-out. The latest drill results entered and exited intervals of outer potassic alteration, providing an important vector towards the potential high-grade potassic core. A second drill rig is now being allocated to target the porphyry and will commence drilling imminently. Highlights include: KARDD0077: 1,151.20 m at 0.30% CuEq (0.11 g/t Au, 2 g/t Ag, 0.16% Cu); KARDD0093G: 800.70 m at 0.33% CuEq (0.14 g/t Au, 1 g/t Ag, 0.17% Cu); KARDD0074: 494.00 m at 0.35% CuEq (0.15 g/t Au, 2 g/t Ag, 0.17% Cu); KARDD0065 (previously reported): 690.40 m at 0.30% CuEq (0.17 g/t Au, 2 g/t Ag, 0.17% Cu). Drill highlights presented above are core lengths (not true widths). Gold equivalent (AuEq) and Copper Equivalent (CuEq) exploration results are calculated using longer-term commodity prices with a copper price of USD 5.00/lb, a silver price of USD 50.00/oz and a gold price of USD 3,500/oz. For AuEq, the following recoveries were applied in-line with the Updated Definitive Feasibility Study: Au – 92.6%, Cu – 94.0%, and Ag – 78.0%. For CuEq, Metallurgical recoveries and net smelter returns are not considered. The diamond drill hole is first logged to determine the sampling intervals, which range from a minimum of 0.1 m to generally 1 m. The drill core is sawn half core cut along a reference line, with the remainder of the core returned to the core tray. Core samples are then placed in numbered calico and plastic bags, with a numbered sample ticket for dispatch to the assay laboratory. Samples are separately assayed for gold, copper and silver. K92’s procedure includes the insertion of standards, blanks and duplicates.
