TORONTO, ONTARIO–(Marketwired – Nov. 2, 2017) –

All amounts are in United States dollars, unless otherwise stated.

Alamos Gold Inc. (TSX:AGI)(NYSE:AGI) ("Alamos" or the "Company") today reported its financial results for the third quarter ended September 30, 2017 and reviewed its operating, exploration and development activities.

"Alamos achieved several milestones in the third quarter including record gold production and our lowest costs and best financial performance in years. This was driven by a breakout quarter from Young-Davidson, which set several new records. We expect this strong performance to continue into the fourth quarter and remain on track to achieve full year production and cost guidance," said John A. McCluskey, President and Chief Executive Officer.

"Within our development portfolio, we achieved initial production at La Yaqui ahead of schedule and commenced early stage construction activities at our Kirazli project. We also announced the acquisition of Richmont Mines through which we are building a stronger and more profitable company. With a growing production base, low cost profile and excellent exploration potential, we believe the Richmont acquisition will be a significant source of value creation for shareholders," Mr. McCluskey added.

Highlight Summary

Outlook and Strategy

The Company's objective is to maximize cash flow from its operations through increased production, margin expansion, and capital discipline, while advancing its portfolio of low-cost development projects. The Company continues to deliver on these objectives, with record production in the third quarter of 107,000 ounces of gold at significantly lower AISC of $884 per ounce driven by record performance at Young-Davidson. Reflecting this strong performance, the Company generated $43.4 million in operating cash flow, and $20.9 million of mine-site free cash flow. In addition, the Company completed construction of La Yaqui Phase I in the quarter, on budget and ahead of schedule. La Yaqui Phase I will generate low-cost production and strong cash flow for approximately three years.

With gold production of 309,100 ounces for the first nine months of 2017, the Company is well positioned to achieve full year guidance of 400,000 to 430,000 ounces. All-in sustaining costs improved significantly in the third quarter, driven by the strong performance of Young Davidson, bringing year-to-date AISC to $946 per ounce. All-in sustaining costs for the year are expected to be consistent with full year guidance of $940 per ounce.

Young-Davidson produced a record 55,800 ounces of gold in the third quarter, an 18% increase from the previous record. Strong production is expected to continue in the fourth quarter driven by higher underground mining rates with the completion of the MCM waste pass in August. In addition, the installation of a pebble crusher to the mill circuit was completed in October, which will support higher mill throughput and further contribute to strong free cash flow in the fourth quarter.

Capital spending at Young-Davidson totaled $22.0 million in the third quarter and $63.3 million year-to-date. The Company expects capital spending to decrease in the fourth quarter, and is tracking to the top end of 2017 guidance of approximately $80 million.

Mulatos produced 36,300 ounces in the third quarter, bringing cumulative year-to-date production to 117,300 ounces. Mulatos is tracking to meet the top end of the full year guidance of 150,000 to 160,000 ounces. Mine-site AISC remained below budget in the third quarter at $864 per ounce ($852 per ounce year-to-date), and are expected to be below guidance of $890 per ounce for the year.

El Chanate produced 14,900 ounces of gold and generated positive mine-site free cash flow in the third quarter. The operation is on track to meet the top end of its production guidance of 50,000 to 60,000 ounces of gold in 2017 at mine-site AISC below guidance of $1,200 per ounce. As a mature, higher cost operation, the Company has hedged El Chanate's 2017 and 2018 production through gold collar contracts which ensure a minimum gold price of $1,270 per ounce and participation up to $1,444 per ounce in 2018. The Company expects the operation to generate stronger free cash flow through residual leaching at the conclusion of its mine life.

Development spending for the remainder of 2017 remains focused on capital spending at Kirazli to complete detailed engineering, site clearing and commence construction activities on longer lead time items, such as the water reservoir. In addition, a feasibility study for the Lynn Lake project is ongoing and is scheduled for completion later this year.

In November, the Company plans to complete the acquisition of Richmont, which owns the Island Gold mine. Island Gold is a low-cost, high-grade, long-life asset in Canada with excellent exploration potential. The acquisition strengthens the Company's asset base, with the addition of a third core, producing asset. Richmont recently released an expansion scenario PEA, which supports near-term production growth, declining costs, and cash flow growth. The acquisition will further strengthen Alamos' balance sheet through diversification and financial flexibility and delivers corporate, tax and other synergies with two underground mines in Ontario. The transaction is subject to shareholder approval and scheduled to close on November 23, 2017.

With the completion of the bought deal equity financing in February and subsequent repayment of the $315 million Notes in April, the Company is debt free and has significantly de-risked its balance sheet. With a substantial cash position, $400 million of liquidity available under the expanded credit facility, and growing cash flow from its operations, the Company is well positioned to fund its strong pipeline of growth projects.

Third Quarter 2017 Results

Young-Davidson Operational and Financial Review

Young-Davidson produced a record 55,800 ounces of gold in the third quarter of 2017, 28% higher than the same period of 2016 and 18% higher than the previous record set in the second quarter of 2017. The substantial increase in production reflects higher underground grades mined, higher mining rates, and an increase in mill throughput during the quarter.

The Company mined 602,072 tonnes of ore from underground in the third quarter of 2017, or 6,544 tpd, a 20% increase from the prior year period. The increase in underground mining rates accelerated further in September, averaging 6,900 tpd following completion of the MCM waste pass. Higher mining rates and mill throughput are expected to continue in the fourth quarter, which will drive strong gold production and free-cash flow.

Underground grades in the third quarter were 2.89 g/t Au, higher than the second quarter of 2017 and the prior year period as higher grade stopes were mined during the quarter. The Company expects underground grades to average the reserve grade of approximately 2.7 g/t Au for the full year.

During the third quarter, 694,900 tonnes or 7,553 tpd were processed through the mill with grades averaging 2.65 g/t Au, higher than the prior year period due to higher underground grades mined. Mill throughput increased compared to the second quarter of 2017, reflecting improvements in the reprocessing of mill scats. With the recent commissioning of the pebble crusher, mill throughput is expected to reach steady state levels of 8,000 tpd during the fourth quarter. Mill recoveries of 93% were consistent with expectations and the prior year period.

Financial Review

For the three months ended September 30, 2017, revenues of $70.8 million were $11.6 million higher than the prior-year period reflecting higher ounces sold, partially offset by a lower realized gold price. For the first nine months of 2017, revenues of $182.9 million was $22.2 million higher than the prior year period, attributable to both higher ounces sold and a higher realized gold price.

In the third quarter of 2017, cost of sales of $53.4 million were higher than the prior year period reflecting higher gross costs as a result of additional tonnes mined and milled. Cost of sales reflects mining and processing costs, royalties, and amortization expense. For the first nine months of 2017, cost of sales of $155.3 million were $15.7 million higher than the prior-year period, also as a result of more tonnes mined and milled.

Total cash costs in the third quarter were $572 per ounce, representing a 6% decrease from the third quarter of 2016. The decrease was attributable to higher grades mined and processed. Underground unit mining costs were $34 per tonne in the third quarter, in line with the prior year period as the benefit of higher underground mining rates was offset by a stronger Canadian dollar. Further strengthening in the Canadian dollar is not expected to adversely impact costs in the fourth quarter as the Company has hedged the majority of its operating and capital costs at CAD:USD of 1.29:1 or better. Mine-site AISC were $744 per ounce, 12% lower than the prior year period reflecting a lower level of sustaining capital across more ounces sold. For the nine months ended September 30, 2017, cash costs were $647 per ounce and mine-site all-in sustaining costs were $824 per ounce, compared to $654 and $887 per ounce, respectively in the comparative period. The decrease was attributable to improved grades, higher underground mining rates and lower sustaining capital expenditures.

Capital expenditures totaled $22.0 million in the third quarter, slightly lower than the same period of 2016 as the reduced capital spending was offset by a stronger Canadian dollar. For the first nine months of 2017, capital expenditures of $63.3 million were 12% lower than in the same period in 2016. Capital spending in the third quarter was focused primarily on lateral development in the upper and lower mine, pebble crusher installation, and completion of the MCM waste pass. Total capital expenditures in the third quarter included $9.4 million of sustaining capital and $12.6 million of growth capital. Capital spending at Young-Davidson is expected to be approximately $80 million in 2017, a significant reduction from 2016 levels.

Young-Davidson generated positive operating cash flow of $35.3 million and record mine-site free cash flow of $13.3 million in the quarter, driven by stronger production and operating margins. For the nine months ended September 30, 2017, Young-Davidson generated $17.8 million of mine-site free cash flow compared to $0.4 million in the prior year period driven by lower capital spending and higher production. Higher underground mining rates are expected to drive strong production and free cash flow through the remainder of 2017.

Mulatos Operational and Financial Review

Financial and operating results at Mulatos for the third quarter of 2017 include La Yaqui phase I, as commercial production commenced in September 2017.

Mulatos produced 36,300 ounces of gold in the third quarter of 2017, including production from La Yaqui Phase I. Production in the quarter was slightly lower than the prior year period due to an increase of leach pad inventory. This is typical for the third quarter rainy season in Mexico and production in the fourth quarter will benefit as this inventory is drawn down. In the month of October, Mulatos produced approximately 13,000 ounces and is expected to come in near the top end of its annual production guidance of 150,000 to 160,000 ounces for the full year.

Total crusher throughput averaged 19,300 tpd, well above the same period of 2016, supplemented by La Yaqui Phase I for the months of August and September. A total of 1,748,328 tonnes were stacked in the third quarter, at a grade of 0.96 g/t Au, both higher than the same period of 2016 due to a combination of mine sequencing, positive grade reconciliation and the addition of higher grade tonnes from La Yaqui Phase I. The waste-to-ore ratio of 0.62:1 was lower than the prior year period and 2017 guidance due to mine sequencing and the addition of La Yaqui which has a minimal waste-to-ore ratio.

La Yaqui Phase I construction was completed in the third quarter, ahead of schedule and on budget. In the third quarter, approximately 170,000 tonnes of ore were stacked on the La Yaqui Phase I leach pad and at average grades of 1.4 g/t, for a total of approximately 7,500 contained ounces. Approximately 2,800 ounces were produced during the third quarter, supplementing Mulatos' production. La Yaqui Phase I is expected to contribute annual production of approximately 25,000 ounces at significantly lower cash costs.

Underground tonnes mined from San Carlos during the quarter were lower than the same period of 2016 and the second quarter of 2017 as the deposit approaches the end of its current mineral reserve life. In the third quarter, 30,769 tonnes were milled at an average grade of 10.05 g/t Au. The Company expects production from San Carlos to continue at reduced levels for the remainder of 2017, with stockpiles continuing to supplement mill feed. At the end of September, the Company had approximately 35,000 tonnes remaining in high grade stockpiles. The Company continues to explore at San Carlos with the objective of extending its mine life into 2018.

The ratio of ounces produced to contained ounces stacked and milled (or recovery ratio) was 57% in the quarter compared to 72% in the prior year period, reflecting the third quarter rainy season and the ramp-up of operations at La Yaqui Phase I. The Company expects recoveries to increase in the fourth quarter.

Financial Review

For the three months ended September 30, 2017, revenues of $38.9 million was $5.8 million lower than the prior-year period reflecting lower ounces sold. A combination of lower production and the timing of both dore and concentrate sales impacted revenues for the quarter, and are expected to be caught up during the fourth quarter. For the first nine months of 2017, revenues of $137.4 million was $10.9 million higher than the prior year, attributable to both higher ounces sold and a higher realized gold price.

Cost of sales in the third quarter of $29.0 million were lower than the prior-year period as gross costs decreased as a result of a lower waste-to-ore ratio and depreciation. Cost of sales reflects mining and processing costs, royalties, and amortization expense. For the first nine months of 2017, cost of sales of $105.3 millionwere $2.5 million lower than the prior-year period as a result of lower depreciation per ounce.

Total cash costs of $785 per ounce in the third quarter were lower than $888 per ounce in the prior year period, reflecting higher grades stacked, a lower waste-to-ore ratio, and the addition of lower cost La Yaqui Phase I production. Mine-site AISC in the quarter were $864 per ounce, $101 or 10% lower than the prior year period reflecting lower total cash costs and lower sustaining capital. For the nine months ended September 30, 2017, cash costs were $782 per ounce and mine-site AISC were $852 per ounce, reflecting higher grades stacked, lower waste-to-ore ratio and lower cost La Yaqui Phase I ounces.

Mulatos had another strong quarter from a cash flow perspective, generating $5.9 million in mine-site free cash flow, excluding $1.7 million of construction capital at La Yaqui Phase I ($12.5 million year-to-date). Mulatos' free cash flow reflects strong earnings from operations, an increase in Value Added Tax ("VAT) refunds and lower sustaining capital. The Company expects free cash flow growth in the fourth quarter of 2017 as production from La Yaqui Phase I increases.

El Chanate Operational and Financial Review

El Chanate produced 14,900 ounces of gold in the third quarter compared to 17,099 ounces in the prior year period. Quarterly production decreased in the third quarter as a result of a lower number of contained ounces stacked during the pit pushback in the first half of 2017. El Chanate is expected to continue to produce at lower than historical rates during the fourth quarter of 2017. The number of contained ounces stacked increased in the third quarter and is expected to continue at similar levels in the fourth quarter of 2017, which will benefit gold production in 2018. On a year-to-date basis, El Chanate has produced 48,300 ounces and is expected to meet the top end of its production guidance of 50,000 to 60,000 ounces.

During the third quarter of 2017, a total of 1,625,109 tonnes of ore were mined at an average grade of 0.48 g/t Au. Tonnes mined were lower than the prior year period reflecting less run-of-mine material, however the impact on production is minimal given its low grade. The waste-to-ore ratio declined compared to the first half of 2017 and the same period of 2016 following completion of the pit pushback in the second quarter of 2017.

The Company stacked 1,537,874 tonnes of open pit ore on the heap leach pad, including run-of-mine material, during the third quarter at an average rate of 16,700 tpd. Tonnes stacked were lower than the prior year period but higher than the first half of 2017.

Financial Review

For the three months ended September 30, 2017, revenue of $19.1 million was $2.6 million lower than the prior year period, reflecting less ounces sold and lower realized gold prices. For the first nine months of 2017, revenue of $60.8 million was slightly lower than the prior year, attributable to less ounces sold, offset by higher realized prices.

For the third quarter, cost of sales were lower than the prior-year period, decreasing by $1.3 million to $18.2 million as a result of a lower waste-to-ore ratio and lower amortization per ounce. Cost of sales reflects mining and processing costs, royalties, and amortization expense. For the first nine months of 2017, cost of sales of $59.6 million were consistent with the prior-year period.

Total cash costs of $1,137 per ounce and mine-site all-in sustaining costs of $1,164 per ounce in the third quarter increased from the same period of 2016 due to lower grades stacked during the year. For the nine months ended September 30, 2017, total cash costs were $1,156 per ounce and mine-site AISC were $1,187 per ounce, attributable to lower grades stacked, and a higher waste-to-ore ratio.

El Chanate generated positive free cash flow of $1.7 million after changes in working capital, and $3.0 million on a year-to-date basis. Given El Chanate's higher cost structure, the Company has executed a hedging strategy to preserve free cash flow, ensuring a minimum gold price of $1,244 per ounce and participation up to a price of $1,407 per ounce on remaining production in 2017. The Company has also hedged 2018 expected production ensuring a minimum gold price of $1,270 and participation up to a price of $1,444 per ounce.

Third Quarter 2017 Development Activities

La Yaqui Phase I

During the third quarter of 2017, the Company spent $1.7 million on development activities to complete construction of the first phase of La Yaqui ($12.5 million year-to-date). In early September the Company announced the completion of construction and commercial production at La Yaqui Phase I ahead of schedule and within budget. La Yaqui Phase I is expected to contribute annual production of approximately 25,000 ounces at significantly lower cash costs.

Lynn Lake

The Company owns 100% of the Lynn Lake development project, in Manitoba, Canada. The Company is currently working towards completion of a feasibility study expected to be completed in the fourth quarter of 2017. During the third quarter, $2.8 million was spent at Lynn Lake ($9.2 million, year to date) on development and exploration activities. During the quarter the Company was focused on completing feasibility level engineering work on the following:

• Process Plant
• Metallurgical test work program
• Onsite and offsite infrastructure
• Mine plans and pit design at both Gordon and MacLellan Sites
• Manitoba Hydro Scoping/PFS level study

In the second quarter of 2017, the Company purchased and canceled a 2.0% net smelter return ("NSR") royalty on the project for $6.7 million.

Turkey

The Company received Forestry Permits for the Kirazli gold project at the beginning of 2017 and continues to pursue the GSM (Business Opening and Operation) permit, which is granted by the Çanakkale Governorship.

In April, the Company increased its planned spending in 2017 for its Turkish projects. In the third quarter, the Company began road construction, commenced tree clearing of the site, and started work on the road relocation and power line construction. Additionally, the Company is in the process of tendering significant contracts, including the civil works contract and water reservoir.

For the three and nine months ended September 30, 2017, total development expenditures in Turkey were $2.3 million and $10.5 million respectively, which includes a forestry permit fee of $5.1 million that was paid in the second quarter of 2017.

Other

The Company capitalized $0.6 million related to the Esperanza Project ($1.7 million, year to date) and capitalized $1.1 million to Quartz Mountain ($1.8 million, year to date) during the third quarter.

Third Quarter 2017 Exploration Activities

Mulatos District

The Company has a large exploration package covering 28,777 hectares which has historically had the majority of its exploration efforts focused around the Mulatos mine. Using knowledge and understanding gained from the successful exploration programs at La Yaqui and Cerro Pelon, a detailed review and ranking of all prospects in the district was undertaken in 2016, with multi-year exploration plans outlined. These programs commenced in 2017 with a number of new prospects currently undergoing initial exploration.

La Yaqui Grande

The Company continued drilling at La Yaqui Grande during the third quarter, with a total of 5,394 metres ("m") of drilling undertaken in 42 holes. The majority of the drilling was conducted in Zone 3, in addition to infill drilling conducted between Zones 2 and 3. The best oxide mineralization in Zone 3 has been intersected in the southwestern portion of the zone. New highlight intercepts from Zone 3 during the third quarter include:

• 17YAQ118: 35.60m at 3.07 g/t Au (79.3 – 114.90m) including 4.7m at 9.12 g/t Au

True widths for these intercepts are estimated at approximately 80-90% of drilled width. Further highlights from the 2017 drill program at La Yaqui Grande are presented in Table 1 at the end of this press release.

Re-logging and re-mapping programs were started earlier in the year and completed in the third quarter, as well as compilation of 3D geological models of structure, alteration and lithology. The plan for the fourth quarter is to complete outstanding infill drilling and resource modelling.

El Refugio

Drilling over the first section of El Refugio commenced in the quarter with 2,934m drilled in nine holes, with results outstanding. Mapping and sampling also continued over the larger El Refugio prospect with additional drilling to be planned as appropriate.

Lynn Lake

Exploration drilling continued at Lynn Lake during the third quarter of 2017 with 6,857 m drilled in 22 holes at the MacLellan, Gordon and Burnt Timber deposits.

At MacLellan, drilling continued to step out along strike to the northeast of a newly outlined zone of mineralization adjacent to the pit. At Gordon drilling was undertaken around the planned pit to test ideas compiled during newly completed structural and vein studies. A re-logging and re-study of the Burnt Timber and Linkwood deposits is currently underway and scout step-out drilling from known mineralization also commenced during the quarter. A total of 15 holes and 4,712m of drilling was completed, with encouraging initial results.

New highlight intercepts obtained during the quarter include the following:

Further highlights from the 2017 drill program at Lynn Lake are presented in Table 2 at the end of this press release.

The plan for the remainder of 2017 is to continue step-out scout drilling at Burnt Timber and to start testing anomalies outlined by geophysical re-interpretation, mapping and sampling conducted earlier in the year.

Review of Third Quarter Financial Results

During the third quarter of 2017, the Company sold 100,551 ounces of gold for proceeds of $128.8 million, a 3% increase compared to the prior year period. This reflected higher ounces sold (a $7.4 million benefit), partially offset by a lower average realized price of $1,281 per ounce compared to $1,325 per ounce in the prior year period (a $4.2 million reduction). The Company's realized gold price in the third quarter was $3 above the average London PM fix of $1,278 per ounce.

For the third quarter of 2017, cost of sales were $100.6 million, compared to $102.2 million in the prior-year period.

Mining and processing costs remained consistent in the third quarter at $69.2 million compared to $70.9 million in the prior-year period.

Consolidated total cash costs for the quarter were $720 per ounce, compared to $785 in the prior year period. The decrease in cash costs is attributable to higher grades mined at Young-Davidson and Mulatos.

In the third quarter, AISC per ounce decreased to $884 from $979 in the prior year period. This was primarily driven by lower mining and processing costs and lower sustaining capital expenditures.

Royalty expense was lower in the third quarter at $3.2 million, compared to $3.5 million in the prior year period, primarily due to fewer ounces sold at Mulatos, and lower realized prices in the quarter compared to the prior year period. This was offset by higher ounces sold at Young-Davidson.

Amortization of $28.2 million in the third quarter was consistent with the prior year. Amortization was $280 per ounce, down from $293 per ounce in the third quarter of 2016. This reflected lower amortization at Mulatos and El Chanate.

The Company recognized earnings from operations of $20.9 million in the third quarter, compared to $17.2 million in the same period of 2016, driven by higher production and gold sales and stronger operating margins, partially offset by lower average realized prices and higher exploration expenses.

The Company reported net earnings of $28.8 million in the third quarter of 2017, compared to net earnings of $4.8 million in the same period of 2016. Higher net earnings in the current quarter reflect stronger earnings from operations, and a deferred tax recovery resulting primarily from the strengthening of the Canadian dollar on the Company's Canadian dollar denominated tax assets.

Cautionary Note to U.S. Investors Concerning Measured, Indicated and Inferred Resources

The Company is required to prepare its resource estimates in accordance with standards of the Canadian Institute of Mining, Metallurgy and Petroleum referred to in Canadian National Instrument 43-101 (NI 43-101). These standards are materially different from the standards generally permitted in reports filed with the United States Securities and Exchange Commission. When describing resources we use the terms "measured", "indicated" or "inferred" resources which are not recognized by the United States Securities and Exchange Commission. The estimation of measured resources and indicated resources involve greater uncertainty as to their existence and economic feasibility than the estimation of proven and probable reserves. U.S. investors are cautioned not to assume that any part of measured or indicated resources will ever be converted into economically or legally mineable proven or probable reserves. The estimation of inferred resources may not form the basis of a feasibility or other economic studies and involves far greater uncertainty as to their existence and economic viability than the estimation of other categories of resources.

Non-GAAP Measures and Additional GAAP Measures

The Company has included certain non-GAAP financial measures to supplement its Consolidated Financial Statements, which are presented in accordance with IFRS, including the following:

• cash flow from operating activities before changes in working capital and taxes received;
• mine-site free cash flow;
• total cash cost per ounce of gold sold;
• all-in sustaining cost ("AISC") per ounce of gold sold;
• mine-site all-in sustaining cost ("Mine-site AISC") per ounce of gold sold;
• sustaining and non-sustaining capital expenditures; and
• earnings before interest, taxes, depreciation, and amortization

The Company believes that these measures, together with measures determined in accordance with IFRS, provide investors with an improved ability to evaluate the underlying performance of the Company. Non-GAAP financial measures do not have any standardized meaning prescribed under IFRS, and therefore they may not be comparable to similar measures employed by other companies. The data is 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. Management's determination of the components of non-GAAP and additional measures are evaluated on a periodic basis influenced by new items and transactions, a review of investor uses and new regulations as applicable. Any changes in to the measures are dully noted and retrospectively applied as applicable.

Cash Flow from Operating Activities before Changes in Working Capital and Cash Taxes

"Cash flow from operating activities before changes in working capital and cash taxes" is a non-GAAP performance measure that could provide an indication of the Company's ability to generate cash flows from operations, and is calculated by adding back the change in working capital and taxes received to "Cash provided by (used in) operating activities" as presented on the Company's consolidated statements of cash flows. "Cash flow from operating activities before changes in working capital" is a non-GAAP financial measure with no standard meaning under IFRS.

The following table reconciles the non-GAAP measure to the consolidated statements of cash flows.

Mine-site Free Cash Flow

"Mine-site free cash flow" is a non-GAAP financial performance measure calculated as cash flow from mine-site operating activities, less mineral property, plant and equipment expenditures. The Company believes this to be a useful indicator of our ability to operate without reliance on additional borrowing or usage of existing cash. Free cash flow is intended to provide additional information only and does not have any standardized meaning under IFRS and may not be comparable to similar measures of performance presented by other mining companies. Free cash flow should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS.

Total Cash Costs per ounce

Total cash costs per ounce is a non-GAAP term typically used by gold mining companies to assess the level of gross margin available to the Company by subtracting these costs from the unit price realized during the period. This non-GAAP term is also used to assess the ability of a mining company to generate cash flow from operations. Total cash costs per ounce includes mining and processing costs plus applicable royalties, and net of by-product revenue and net realizable value adjustments. Total cash costs per ounce is exclusive of exploration costs.

Total cash costs per ounce is intended to provide additional information only and does not have any standardized meaning under IFRS and may not be comparable to similar measures presented by other mining companies. It should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. The measure is not necessarily indicative of cash flow from operations under IFRS or operating costs presented under IFRS.

All-in Sustaining Costs per ounce and Mine-site All-in Sustaining Costs

The Company adopted an "all-in sustaining costs per ounce" non-GAAP performance measure in accordance with the World Gold Council published in June 2013. The Company believes the measure more fully defines the total costs associated with producing gold; however, this performance measure has no standardized meaning. Accordingly, there may be some variation in the method of computation of "all-in sustaining costs per ounce" as determined by the Company compared with other mining companies. In this context, "all-in sustaining costs per ounce" for the consolidated Company reflects total mining and processing costs, corporate and administrative costs, share-based compensation, exploration costs, sustaining capital, and other operating costs.

For the purposes of calculating "mine-site all-in sustaining costs" at the individual mine-sites, the Company does not include an allocation of corporate and administrative costs and share-based compensation, as detailed in the reconciliations below.

Sustaining capital expenditures are expenditures that do not increase annual gold ounce production at a mine site and excludes all expenditures at the Company's development projects as well as certain expenditures at the Company's operating sites that are deemed expansionary in nature. For each mine-site reconciliation, corporate and administrative costs, and non-site specific costs are not included in the all-in sustaining cost per ounce calculation.

All-in sustaining costs per gold ounce is intended to provide additional information only and does not have any standardized meaning under IFRS and may not be comparable to similar measures presented by other mining companies.

It should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS.

The measure is not necessarily indicative of cash flow from operations under IFRS or operating costs presented under IFRS.

Total Cash Costs and All-in Sustaining Costs per Ounce Reconciliation Tables

The following tables reconciles these non-GAAP measures to the most directly comparable IFRS measures on a Company-wide and individual mine-site basis.

Earnings Before Interest, Taxes, Depreciation, and Amortization ("EBITDA")

EBITDA represents net earnings before interest, taxes, depreciation, and amortization. EBITDA is an indicator of the Company's ability to generate liquidity by producing operating cash flow to fund working capital needs, service debt obligations, and fund capital expenditures.

EBITDA does not have any standardized meaning under IFRS and may not be comparable to similar measures presented by other mining companies. It should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS.

The following is a reconciliation of EBITDA to the consolidated financial statements:
