Non-IFRS Financial Information

Adjusted Net Profit/(Loss) and Adjusted Earnings/(Loss) per share

These are used by Management to measure the underlying operating performance of the Company. Management believes these measures provide information that is useful to investors because they are important indicators of the strength of the Company's operations and the performance of its core business. Accordingly, such measures are intended to provide additional information and should not be considered in isolation as a substitute for measures of performance prepared in accordance with IFRS. Adjusted Net Profit/(Loss) is calculated as Net Profit/(Loss) less the impact of impairment expenses and reversals, write-downs, foreign exchange (gains)/losses, gain on sale of assets and listing costs.

The following table provides a reconciliation of Adjusted Net Profit/(Loss) and Adjusted Earnings/(Loss) per share:

EBITDA, Adjusted EBITDA and Adjusted EBITDA Margin

Management believes that Adjusted EBITDA is a valuable indicator of its ability to generate liquidity by producing operating cash flows to fund working capital needs, service debt obligations and fund capital expenditures. EBITDA is defined as earnings before interest, tax, depreciation and amortization. Adjusted EBITDA is calculated as EBITDA less the impact of impairment expenses and reversals, write-downs, gains/losses on disposal of assets, listing costs, foreign exchange gains/losses and other non-recurring costs. Adjusted EBITDA Margin is calculated as Adjusted EBITDA divided by revenue.

The following table provides a reconciliation of EBITDA, Adjusted EBITDA and Adjusted EBITDA Margin:

Cash Costs and AISC

Cash Costs are a common financial performance measure in the gold mining industry; however, it has no standard meaning under IFRS. Management uses this measure to monitor the performance of the Company's mining operations and its ability to generate positive cash flows, both on an individual site basis and an overall company basis. Cash Costs include mine site operating costs plus indirect taxes and selling cost net of by-product allocations and are then divided by ounces sold. In calculating Cash Costs, the Company includes the value of cash-settled stock-based compensation in the year of vesting. Cash Costs are reduced by copper and silver by-product cost allocations that are considered incidental to the gold production process, thereby allowing Management and other stakeholders to assess the net costs of gold production. The measure is not necessarily indicative of cash flow from operations under IFRS or operating costs presented under IFRS.

Management believes that the AISC measure provides additional insight into the costs of producing gold by capturing all of the expenditures required for the discovery, development and sustaining of gold production and allows the Company to assess its ability to support capital expenditures to sustain future production from the generation of operating cash flows, both on an individual site basis and an overall company basis, while maintaining current production levels. Management believes that, in addition to conventional measures prepared in accordance with IFRS, certain investors use this information to evaluate the Company's performance and ability to generate cash flow per ounce sold. AISC is calculated as the sum of Cash Costs, capital expenditures and exploration costs that are sustaining in nature and corporate G&A costs. AISC is divided by ounces sold to arrive at AISC per ounce.

 The following table provides a reconciliation of consolidated Cash Costs and AISC:

Macraes

Waihi

Net Cash/(Debt)

Net Cash/(Debt) has been calculated as total debt plus cash and cash equivalents. Management believes this is a useful indicator to be used in conjunction with other liquidity and leverage ratios to assess the Company's financial health.

The following table provides a reconciliation of Net Cash/(Debt):

Operating Cash Flow before working capital movements

Operating Cash Flow before working capital movements is calculated as the cash flows provided by operating activities adjusted for changes in working capital. The following table provides a reconciliation of Operating Cash Flow before working capital movements:

Free Cash Flow

Free Cash Flow is calculated as cash flows from operating activities, less cash flow used in investing activities. Management believes Free Cash Flow is a useful indicator of the Company's ability to generate cash flow and operate net of all expenditures, prior to any financing cash flows. The following table provides a reconciliation of Free Cash Flow:
