April 25, 2018
  • Drill Hole KMDD0084 records multiple intersections including 5.82 m at 486.78 g/t Au, 21 g/t Ag and 0.15% Cu (487.1 g/t Au Eq) plus 4.68 m at 73.54 g/t Au, 4 g/t Ag and 0.33% Cu (74.1 g/t AuEq)
  • Drill Hole KMDD0082 records multiple intersections including 2.75 m at 21.41 g/t Au, 6 g/t Ag and 1.13% Cu (23.20 g/t AuEq) plus 3.78 m at 32.54 g/t Au, 62 g/t Ag and 2.59% Cu (37.29 g/t AuEq)             

VANCOUVER, British Columbia, April 25, 2018 (GLOBE NEWSWIRE) -- K92 Mining Inc. (“K92”) (TSXV:KNT) (OTCQB:KNTNF) is pleased to announce results from the continuing grade control drilling of the Kora North Extension.

The results reported are from the first two holes from the new Diamond Drill Cuddy Three (DDC3), with both holes drilled recording intersections of the K1, KL and K2 Lodes.

Results from Hole KMDD0084 included 5.82 m at 486.78 g/t Au, 21 g/t Ag and 0.15% Cu (487.1 g/t Au Eq) plus 4.68 m at 73.54 g/t Au, 4 g/t Ag and 0.33% Cu (74.1 g/t AuEq) plus 4.12 m at 7.59 g/t Au, 21 g/t Ag and 1.92% Cu (10.79 g/t AuEq), while Hole KMDD0082 recorded 2.75 m 21.41 g/t Au, 6 g/t Ag and 1.13% Cu (23.20 g/t AuEq) plus 3.78 m at 32.54 g/t Au, 62 g/t Ag and 2.59% Cu (37.29 g/t AuEq) plus 3.31 m at 8.37 g/t Au, 2 g/t Ag and 0.39% Cu (8.99 g/t AuEq).

The results from DDC3 are now the furthest drilled to the south and continue to confirm the consistency of both the K1 and K2 lodes within this area while also further delineating the KL structure and confirming its continuity. A plan showing the Kora North development, location of the three diamond drill cuddies and of the latest grade control drill holes is provided below.

John Lewins, K92 Chief Executive Officer and Director, states, “The first hole drilled from the new drill cuddy DDC3, KMDD0082 was possibly our best hole to date however this has been totally eclipsed by the results from the second hole, KMDD0084 which included a section of 0.72 metres assaying at over 3,500 g/t Au. These two holes are the furthest south that we have drilled and appear to indicate a general increase in both copper and gold grades as we move further south. Importantly from the perspective of building our confidence in the continuity of the Kora – Irumafimpa system, hole KMDD0084 is just over 200 metres along strike from the deepest hole drilled by Barrick from surface, BKDD0023. This hole reported over 30 metres of continuous mineralization from 920 metres down hole and finished in mineralization as the hole could not be drilled any deeper.

We have already completed the drilling of the next grade control hole from DDC3, which is a further 25 metres to the south, and await the assay results with great anticipation”.

Table 1 below provides a summary of the results from the latest diamond grade control drill holes drilled into the Kora North Vein system from DDC3. Table 2 provides details of collar location and hole orientation.

The current Kora/Eutompi inferred resource, as defined by previous drilling to date, is 4.36 million tonnes at a grade of 7.3 g/t Au, 35 g/t Ag and 2.23 per cent Cu, or 11.2 g/t gold equivalent (see attached table) and is open for expansion at depth and in both directions along strike.

K92 has filed and made available for download on the company's SEDAR profile a technical report titled "Independent Technical Report, Mineral Resource Update and Preliminary Economic Assessment of Irumafimpa and Kora Gold Deposits, Kainantu Project, Papua New Guinea," with an effective date of March 2, 2017, that provides additional information on the geology of the deposits, drilling and sampling procedures, lab analysis, and quality assurance/quality control for the project, and additional details on the resource estimates.

The PEA estimates for Kora, based on the current resource estimates (4.36 million tonnes of 7.3 g/t Au, 35 g/t Ag and 2.23 per cent Cu):

  • Over a nine-year operating life, the plant would treat 3.2 million tonnes averaging 7.1 g/t Au, 25 g/t Ag and 1.7 per cent Cu (9.3 g/t AuEq (1));
  • This would generate an estimated positive cash flow of $537-million (U.S.) using current metal prices if 15-metre levels are used in mining; if 25-metre levels are used, then net cash flows are estimated as $558-million (U.S.); this cash flow includes conceptual allowances for capital;
  • Production of an estimated average of 108,000 AuEq (1) ounces per annum over an eight-year period from year 2 through to year 9;
  • An estimated pretax net present value (NPV) of $415-million (U.S.) for 25-metre levels, or $397-million (U.S.) for 15-metre levels, using current metal prices, exchange rates and a 5-per-cent discount;
  • An estimated after-tax NPV of $329-million (U.S.) for 25-metre levels, or $316-million (U.S.) for 15-metre levels, using current metal prices, exchange rates and a 5-per-cent discount;
  • Initial capital cost is estimated to be $13.8-million (U.S.), including the $3.3-million (U.S.) for the plant upgrade identified in the Mincore scoping study, but excluding the proposed Kora exploration inclines and diamond drilling; sustaining capital cost is estimated to a further $64-million (U.S.) spent over the life of the Kora mining for 25-metre levels, or $83-million (U.S.) for 15-metre levels;
  • Operating cost per tonne is estimated to be $125 (U.S.) per tonne for 25-metre levels, or $126 (U.S.) per tonne for 15-metre mining levels;
  • Excluding initial capital expenditure of $14-million (U.S.), cash cost is estimated to be $547 (U.S.) per ounce AuEq (inclusive of a 2.5-per-cent net smelter return (NSR) royalty) and all-in sustaining cost (AISC) of $619 (U.S.) per ounce AuEq for 25-metre mining levels, or $549 (U.S.) per ounce (inclusive of a 2.5-per-cent NSR royalty) and AISC of $644 (U.S.) per ounce AuEq for 15-metre mining levels.

Metal prices used were $1,300 per ounce for gold, $18 (U.S.) per ounce for silver and $4,800 per tonne for copper.

(1) Gold equivalent calculated on above metal prices.

Kora remains open for expansion in every direction and strongly mineralized at the extent of all drilling.

The PEA is preliminary in nature and includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the PEA will be realized. The technical report contains a full description of all underlying assumptions relating to the PEA. Mineral resources that are not mineral reserves and do not have demonstrated economic viability.
