(“K92” or the “Company”) (TSX-V: KNT; OTCQX: KNTNF) is pleased to announce results from the ongoing diamond drilling of the Kora deposit at the Kainantu gold mine in Papua New Guinea.The results for the latest 12 diamond drill holes completed from surface and underground into the Kora deposit are summarized in Table 1 below. The results continue to demonstrate the high-grade and continuity of Kora with intersections largely focused on increasing drill density towards the South. All drill holes intersected mineralization.The drill results once again intersected a potentially bulk mineable zone. Drill Hole KMDD0230 recorded multiple intersections including 6.21 m at 48.11 g/t Au, 13 g/t Ag and 1.05% Cu (49.82 g/t AuEq, 5.06 m true width) at the K1 Vein. When combining the K1, Kora Link and K2 Veins, KMDD0230 recorded a bulk intersection of 23.66 m at 13.61 g/t Au, 13 g/t Ag and 0.84% Cu (15.02 g/t AuEq, 19.15 m true width).Towards the South, multiple high-grade intersections were also recorded. Following the commissioning of the most southerly underground drill cuddy, the first hole from DDC14, KMDD0225 recorded multiple intersections including 9.00 m at 4.41 g/t Au, 39 g/t Ag and 3.59% Cu (10.21 g/t AuEq, 4.57 m true width) at the K2 Vein.Other high-grade intersection highlights were KMDD0227, KMDD0238 and KMDD0234. KMDD0227 recorded multiple intersections including 4.32 m at 133.40 g/t Au, 4 g/t Ag and 0.25% Cu (133.82 g/t AuEq, 4.21 m true width) at the K1 Vein. KMDD0238 recorded multiple intersections including 4.20 m at 13.22 g/t Au, 6 g/t Ag and 0.20% Cu (13.59 g/t AuEq, 3.02 m true width) at the K1 Vein. KMDD0234 recorded multiple intersections including 10.00 m at 10.11 g/t Au, 10 g/t Ag and 0.28% Cu (10.64 g/t AuEq, 7.95 m true width) at the K2 Vein.Long sections of K1 and K2 showing the location of the latest drill holes are provided in Figures 1 and 2, respectively. Long section showing Kora drilling to date is provided in Figure 3.(Gold Equivalent (AuEq) is calculated using copper price of US$3.05/lb, silver price of US$16.05/oz and gold price of US$1,400/oz.)John Lewins, K92 Chief Executive Officer and Director, stated, “We continue to be very pleased with the high-grade pedigree and continuity from the drilling results at Kora. All twelve holes intersected mineralization with five intersections exceeding +10g/t AuEq and fifteen intersections exceeding +5g/t AuEq. Highlights from the drilling results included: 6.21 m at 48.11 g/t Au, 13 g/t Ag and 1.05% Cu (49.82 g/t AuEq, 5.06 m true width) and 4.32 m at 133.40 g/t Au, 4 g/t Ag and 0.25% Cu (133.82 g/t AuEq, 4.21 m true width), both from the K1 Vein. Once again, a bulk mineable intersection was also reported of 23.66 m at 13.61 g/t Au, 13 g/t Ag and 0.84% Cu (15.02 g/t AuEq, 19.15 m true width) when combining the K1, K Link and K2 veins. To date, multiple bulk mineable areas have been identified and studies to assess the optimal extraction approach will be part of the Stage 3 Expansion Definitive Feasibility Study.As we advance exploration at Kora through the remainder of 2020 and into 2021, we are especially excited about the progress made advancing underground infrastructure to drill test the southern strike extension. Our most southern drill cuddy DDC14 was completed in July, and we received the results from our first hole drilled with KMDD0225 reporting 9.00 m at 4.41 g/t Au, 39 g/t Ag and 3.59% Cu (10.21 g/t AuEq, 4.57 m true width) in the K2 Vein. Development continues to advance to the south and our plan is to have our next drill cuddy established to test beyond the mining lease, into Kora South in Q4.Lastly, we highlight that exploration activities are increasing significantly. Our two new, multi-powered surface drill rigs are expected to arrive on site imminently, increasing the number of drill rigs to nine. By the end of this year we will plan to have ten drill rigs operating and self-funded from mine cash flow. This is enabling the testing of multiple targets concurrently and we plan to provide updates near-term.”
Table 1 – Kainantu Gold Mine – Significant Intercepts from Diamond Drilling(1) Gold Equivalent in Table 1 uses copper price of US$3.05/lb; silver price of US$16.05/oz and gold price of US$1,400/oz.Table 2 – Kainantu Gold Mine – Collar Locations for Kora Diamond DrillingTable 3 – Global Kora Mineral Resource (Effective Date April 2, 2020)Mineral Resource Estimate is included in a technical report titled, “Independent Technical Report, Mineral Resource Estimate Update and Preliminary Economic Assessment for Expansion of the Kainantu Mine to Treat 1 Mtpa from the Kora Gold Deposit, Kainantu Project, Papua New Guinea” with an effective date of April 2, 2020.The Independent and Qualified Person responsible for the Mineral Resource Estimate is Simon Tear, P.Geo. of H & S Consultants Pty. Ltd., Sydney, Australia.Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability.Resources were compiled at 1,2,3,4,5,6,7,8,9 and 10 g/t gold cut-off grades.Density (t/m3) is on a per zone basis, K1 and Kora Link: 2.84 t/m3; K2: 2.93 t/m3; Waste: 2.8 t/m3Reported tonnage and grade figures are rounded from raw estimates to reflect the order of accuracy of the estimate.Minor variations may occur during the addition of rounded numbers.Calculations used metric units (metres, tonnes and g/t)Gold equivalents are calculated as AuEq = Au g/t + ((0.923 x Cu%)*1.38)+ ((0.77 x Ag g/t*0.0115). Gold price US$1,400/oz; Silver US$16.05/oz; Copper US$3.05/lb. Metal payabilities and recoveries are incorporated into the AuEq formula. Recoveries of 92.3% for copper and 77% for silver.Key Assumptions and Parameters – Kora DepositThe Kora Deposit comprises of two parallel, steeply west dipping, north-south striking quartz-sulphide vein systems, K1 and K2, within an encompassing dilatant structural zone hosted by phyllite. An additional structure, the Kora Link, has also been defined between K1 and K2. There are five Kora Link structures identified, of which three are included in the updated resource estimate.The current resource estimate area covers an area of approximately 1,250 metres along strike by 1,050 to 1,150 metres vertically (see Fig 1), representing ~75% of the drill target area. K92 plans to continue to drill the area not yet drilled. The updated resource estimate includes results from 266 diamond drill holes in addition to face samples taken from horizontal development and from cut and fill faces along the K1 and K2 veins.Underground drilling consists of diamond core for a range of core sizes depending on the length of hole and expected ground conditions. Sampling is sawn half core under geological control and generally ranges between 0.5m to 1.0m. Underground face sampling is completed for every fired round and is to industry standard. QAQC data indicated no significant issues with the sampling or the accuracy of the on-site analysis. Current core recovery of the mineral zone is +95%, with initial drilling around the 90% mark.Geological logging is consistent and is based on a full set of logging codes covering lithology, alteration, and mineralization.The geological interpretation of the vein systems is represented as 3D wireframe solids snapped to a combination of diamond drillhole data and underground face sampling (see Fig 1). Definition of the wireframes is based on identified gold mineralization in drill core nominally at a 0.1-0.2g/t Au gold-off in conjunction with geological control/sense and current mining widths.The wireframes were used to extract 1-metre composites (minimum of 0.5m) from the drillhole & sampling database for gold, copper and silver. A gold top cut of 1000g/t was applied to K2 composites and a 150g/t top cut for the Kora Link #2. No top cuts were applied to silver or copper. Variography was generally poor, as would likely be expected, although K1 indicated better along strike grade continuity.Grade interpolation of the composite data was completed using Ordinary Kriging with a block size of 1m by 5m by 5m. A larger block size check model indicated no evidence of over-smoothing of gold grade with the smaller block size.Default average density values have been applied to the different lodes. The defaults are based on limited core measurements using the Archimedes Method (weight in air/weight in water). Density (t/m3) is on a per zone basis, with K1 and Kora Link: 2.84 t/m3; K2: 2.93 t/m3; Waste: 2.8 t/m3A three-pass search strategy was applied to the grade interpolation. Search ellipse parameters are listed below. Search ellipse orientations generally reflected the subtle changes in dip and strike of the vein systems, with up to 8 search domains used for each lode.Qualified PersonK92 mine geology manager and mine exploration manager, Andrew Kohler, PGeo, a qualified person under the meaning of Canadian National Instrument 43-101 – Standards of Disclosure for Mineral Projects, has reviewed and is responsible for the technical content of this news release.
