(2) Non-GAAP Measures

Operating cost, all-in sustaining costs and average realized gold price per ounce are Non-GAAP measures. In the gold mining industry, these are common performance measures but do not have any standardized meaning, and are considered Non-GAAP measures. The Company believes that, in addition to conventional measures prepared in accordance with International Financial Reporting Standards ("IFRS" or "GAAP"), certain investors use such Non-GAAP measures to evaluate the Company's performance and ability to generate cash flow. Accordingly, they are intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. A reconciliation of operating cost per ounce and AISC per ounce to total operating costs for the most recent reporting period, the three and nine months ended September 30, 2016 and October 31, 2015, is set out on the Company's MD&A for the period ended September 30, 2016 filed on SEDAR at www.sedar.com and at www.klgold.com.

Operating Cost per Ounce

Operating costs are disclosed in the notes to the Company's consolidated financial statements and include mine site operating costs such as mining, processing and administration, but exclude royalty expenses, depreciation and depletion, share based payment expenses and reclamation costs. Operating cost per ounce is based on ounces sold and is calculated by dividing operating costs by gold ounces sold.

All-In Sustaining Costs per Ounce

While there is no standardized meaning across the industry for this measure, the Company's definition conforms to the definition of all-in sustaining costs as set out by the World Gold Council in its guidance note dated June 27, 2013. The Company defines AISC as the sum of operating costs, royalty expenses, sustaining capital, corporate expenses, sustaining exploration expenses, and reclamation cost accretion related to current operations. Corporate expenses include general and administrative expenses, net of transaction related costs, severance expenses for management changes and interest income. AISC excludes growth capital, reclamation cost accretion not related to current operations, interest expense, debt repayment and taxes. The costs included in the calculation of all-in sustaining costs are divided by gold ounces sold.

Average Realized Price per Ounce Sold

Average realized price per ounce sold is a Non-GAAP measure. In the gold mining industry, average realized price per ounce sold is a common performance measures but does not have any standardized meaning.

The most directly comparable measure prepared in accordance with GAAP is revenue from gold sales. Average realized price per ounce sold should not be considered in isolation or as a substitute for measures prepared in accordance with GAAP. The measure is intended to assist readers in evaluating the total revenues realized in a period from current operations.
