Over the past several days, while conducting ongoing drilling and face sampling, the Company also completed the mining of an initial bulk sample at Kora, having mined in excess of 2,000 tonnes from a four-metre-by-four-metre horizontal development extending north and south from the previously reported initial cross cut intersection of the Kora Vein. The first 800 tonnes of mined material were processed and the results were described in K92 News Release, October 11, 2017 (K92 Announces Positive Results from Treating the Initial 800 Tonnes of Bulk Sample from the Kora Vein). The remainder of the mined material from the bulk sample is currently being processed with results pending.
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 in PEA 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.

M in Table is millions. Reported 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. Gold equivalents are calculated as AuEq = Au g/t + Cu%*1.52+ Ag g/t*0.0141.
