Mineral Reserves

Total Proven and Probable mineral reserves increased by 31% to 7.7 million ounces of gold at December 31, 2016, reflecting the significant increase in mineral reserves at La Yaqui and the declaration of initial mineral reserves at Kirazlı and Ağı Dağı. This increase was partially offset by mining depletion at Young-Davidson, Mulatos and El Chanate.

At La Yaqui Grande, 521,000 ounces were added to mineral reserves increasing the combined mineral reserve at La Yaqui nearly 600% to 608,000 ounces from the end of 2015. This was achieved as part of a successful 2016 exploration program which saw significant mineral resource additions at La Yaqui Grande through drilling the first eight months of the year, and the successful conversion of these mineral resources to mineral reserves through infill drilling undertaken from September through November. With a significant portion of La Yaqui Grande still to be explored, infill and exploration drilling across this large area of alteration remains a focus in 2017.

At Kirazlı and Ağı Dağı, a significant portion of the Measured and Indicated mineral resources were successfully converted to an initial Proven and Probable mineral reserve totalling 1.8 million ounces of gold across both projects as detailed in the summary results from the two positive feasibility studies released earlier this month.

No exploration drilling was conducted at Young-Davidson or El Chanate in 2016. Exploration activities at Young-Davidson are expected to increase once the lower mine is developed. At Mulatos, limited exploration drilling targeting mineral reserves within the main Mulatos open pit was completed with the focus being on other higher priority targets including La Yaqui. The mineral reserve additions at La Yaqui more than offset depletion from the main Mulatos pit with the combined net mineral reserves at Mulatos increasing 22% to 1.9 million ounces. The Company spent $17 million on exploration at Mulatos in 2016 with a further $17 million budgeted for 2017. A $1,250 per ounce gold price assumption was used in estimating the 2016 mineral reserves, unchanged from 2015. A detailed summary of Proven and Probable mineral reserves as of December 31, 2016 is presented in Table 1 at the end of this press release.

Mineral Resources

Alamos' Measured and Indicated mineral resources (exclusive of mineral reserves) totaled 9.3 million ounces as of December 31, 2016. This represents a 14% decrease in ounces and 14% increase in grade from December 31, 2015. The decrease in ounces reflects the conversion of mineral resources at Kirazlı and Ağı Dağı to mineral reserves, partially offset by additions at Young-Davidson and La Yaqui. The additions of higher grade ounces at Young-Davidson and La Yaqui also contributed to the increase in grade, along with the conversion of mineral resources at the Turkish projects.

Alamos' total Inferred mineral resources of 4.3 million ounces as of December 31, 2016 were down slightly from 2015 reflecting the successful conversion of mineral resources at La Yaqui Grande to mineral reserves and higher mineral resource classifications.

The Company's $1,400 per ounce gold price assumption for estimating mineral resources is unchanged from 2015. Detailed summaries of the Company's Measured and Indicated, and Inferred mineral resources as of December 31, 2016 are presented in Tables 3 and 4 respectively, at the end of this press release.

Young-Davidson

Mineral reserves at Young-Davidson decreased 0.2 million ounces, to 3.7 million ounces of gold reflecting mining depletion. However, the Company added 0.3 million ounces of Measured and Indicated mineral resources through infill drilling.

Young-Davidson has excellent exploration potential with the deposit open at depth; however, with a large mineral reserve base and it being cost prohibitive to drill from surface, exploration is not a near term focus. As such, no exploration drilling was undertaken in 2016. The Company will resume exploration activities once the lower mine has been developed allowing for exploration drilling platforms at depth.

In addition to the underground mineral reserves, the Company has 1.2 million tonnes of surface stockpiles grading 0.91 grams per tonne of gold ("g/t Au") which will be used to supplement higher grade underground ore until underground mining rates ramp up to the mill capacity. Based on expected underground mining rates, the remaining mineral reserve life of the Young-Davidson mine is approximately 15 years as of December 31, 2016.

As noted above, underground Measured and Indicated mineral resources at Young-Davidson increased 33%, or 0.3 million ounces to 1.2 million ounces. These additions came through infill drilling in the upper portion of the lower mine. The Company expects a strong conversion rate to mineral reserves through additional stope definition and infill drilling and further potential to add to the mineral resource base. Inferred mineral resources were largely unchanged at 0.3 million ounces.

Mulatos

Mulatos open pit, heap leach mineral reserves (including the Mulatos Mine, stockpiles, La Yaqui and Cerro Pelon) increased 24%, or 0.36 million ounces, to 1.8 million ounces. This reflects the 0.52 million ounce increase in mineral reserves at La Yaqui Grande, partially offset by mining depletion in the Mulatos Mine. The mineral reserve grade also increased 11% to 1.15 g/t Au with the addition of the higher grade La Yaqui Grande ounces. This is approximately 38% above the 2017 budgeted grade for open pit, heap leach production (based on the mid-point of guidance).

The mineral reserve grade of the Mulatos Mine, the current source of open pit, heap leach production, increased slightly to 0.90 g/t Au, reflecting lower grade ounces mined in 2016.

Based on the 2017 budgeted throughput rates, the remaining mineral reserve life of the Mulatos Mine (including stockpiles) is approximately five years as of December 31, 2016, exclusive of La Yaqui and other surrounding deposits.

Underground mineral reserves at Mulatos decreased 21,000 ounces reflecting mining depletion at San Carlos. The depletion of 55,000 tonnes was well below the 134,000 tonnes milled with the Company encountering and mining ore outside of the existing mineral reserves. Based on current mineral reserves and stockpiles, the Company has sufficient ore to continue high grade mill production to the fourth quarter of 2017, though this could be extended if mining continues outside of existing reserves.

Measured and Indicated mineral resources at Mulatos of 2.8 million ounces are largely unchanged. Inferred mineral resources at Mulatos decreased 0.16 million ounces reflecting the conversion of the Inferred mineral resource at La Yaqui Grande to mineral reserves.

La Yaqui

The initial mineral reserve at La Yaqui Grande of 521,000 ounces brings the combined mineral reserves at La Yaqui to 608,000 ounces. The significant increase in mineral reserves at La Yaqui (from 89,000 ounces a year ago) was the result of a very successful exploration program in 2016 which included 46,809 metres of drilling that was designed to both upgrade and expand the 232,000 ounces of inferred mineral resource discovered in Zones 1 and 2 of La Yaqui Grande.

The Company was successful on both fronts with drilling through the first eight months of the year incorporated into the interim mineral resource update in September 2016. This included the conversion of 149,000 ounces (4.1 million tonnes grading 1.14 g/t Au) to an indicated mineral resource and expanding the higher grade inferred mineral resource to 298,000 ounces (5.5 million tonnes grading 1.68 g/t Au) for a total of 447,000 ounces of combined mineral resources as of September 2016.

The primary focus for the remainder of 2016 (September to the end of November) was infill drilling the larger mineral resource base contained within Zones 1 and 2, some extension drilling between the zones and scout drilling of a third zone to the north. The program was again successful in adding further mineral resource growth within La Yaqui Grande and upgrading most of the mineral resources to an initial mineral reserve of 521,000 ounces.

In addition to the mineral reserve growth, La Yaqui Grande contains a Measured and Indicated mineral resource of 68,000 ounces and Inferred mineral resource of 8,000 ounces. The overall size and confidence of the mineral reserve and resource base has increased substantially from a year ago, with combined mineral reserves and resources at La Yaqui increasing 113% to now total 684,000 ounces, the majority of which are mineral reserves.

The Company has another aggressive exploration program planned for La Yaqui Grande in 2017 with the aim of further growing the mineral reserve and resource base. The focus will be infill drilling within Zone 3, drilling the gaps between all three zones and down-dip (to the northeast) of Zones 2 and 3. Exploration drilling will also be conducted over the eastern part of Zone 1, along the Yaqui Norte - Halcon corridor and on the narrow, steeply dipping rib of silica alteration to the southeast of Zone 1. Approximately $6 million has been budgeted for exploration at La Yaqui Grande in 2017.

Other Mulatos District Exploration Plans for 2017

  • Cerro Pelon - The exploration focus at Cerro Pelon changed mid-2016 to include a much larger area. Scout drilling on the western zone intersected vuggy silica, advanced argillic alteration and sulphide mineralization. Grades improved from anomalous to ore-grade and these will be followed up in 2017. Additional exploration over the northern silica cap and the eastern rib will also be undertaken. The focus of the 2017 exploration program is to continue to systematically explore the larger Cerro Pelon area, with particular focus on the western zone. The 2017 exploration budget at Cerro Pelon is $4 million.
  • Los Bajios - The Los Bajios target is in close proximity to the main Mulatos mine. Wide intercepts of oxide mineralization and a large alteration anomaly were outlined from exploration programs prior to 2007. Mapping, sampling and Induced Polarization Surveys were carried out over Los Bajios in the fourth quarter of 2016. This work along with the historical work will form the basis of phased exploration drill programs through 2017 which will commence in the first half of the year. Approximately $2 million has been budgeted for exploration at Los Bajios in 2017.
  • El Refugio, El Carricito and El Halcon - El Refugio is located immediately along strike from the Puerto del Aire Deposit which is directly adjacent to the Mulatos open pit mine. Preliminary mapping conducted here in 2016 indicates the presence of out-cropping high grade gold mineralization associated with pyrite-barite veins, similar to that seen in San Carlos. Mapping, sampling and geophysics will be conducted on El Refugio with the aim to be ready for scout drilling in the second half of 2017. Mapping, sampling and geophysics will also be conducted on the El Carricito and El Halcon prospects, with the aim of working those up to drill-ready status in 2018. Approximately $5 million has been budgeted for these prospects in 2017.

Kirazlı, Ağı Dağı and Camyurt

An initial mineral reserve totaling 1.8 million ounces was declared on the Kirazlı and Ağı Dağı projects with the successful conversion of a large portion of each projects' Measured and Indicated mineral resources. This was outlined in two separate feasibility studies completed on the projects, both outlining very attractive economics.

An initial Proven and Probable mineral reserve was declared on Kirazlı totaling 0.67 million ounces of gold and 10.1 million ounces of silver. The project also hosts a Measured and Indicated mineral resource of 0.08 million ounces of gold and 0.4 million ounces of silver. This is down from a year ago reflecting its conversion to mineral reserves. Kirazlı's Inferred mineral resource of 0.11 million ounces of gold and 1.6 million ounces of silver is contained within the mineral reserve pit and is treated as waste in the feasibility mine plan. This represents an opportunity to add to the total mineable ounces through additional drilling.

Based on the feasibility mine plan, Kirazlı has an expected mineral reserve life of 5 years. The project hosts good exploration potential with favourable alteration extending up to 400 metres west of the pit with previous drilling in this area intersecting mineralization. In addition, further exploration potential exists on the Catalkaya and Kale prospects that sit to the south of the Kirazlı Main Zone.

Ağı Dağı contains Proven and Probable mineral reserves totaling 1.2 million ounces of gold and 9.5 million ounces of silver. The project also hosts Measured and Indicated mineral resources of 0.52 million ounces of gold and 2.5 million ounces of silver. As with Kirazlı, this is down from a year ago reflecting its conversion to mineral reserves. A further 0.25 million ounces of gold and 1.5 million ounces of silver are contained in the Inferred mineral resource category. Of the Inferred mineral resource, 74,000 ounces of gold is contained within the mineral reserve pit and treated as waste in the feasibility mine plan. This represents an opportunity to add to the total mineable ounces through additional drilling.

Based on the feasibility mine plan, Ağı Dağı has an expected mineral reserve life of 6 years. As detailed in the preliminary economic assessment for Camyurt, trucking its mineralized material over to Ağı Dağı could extend the mine life to nearly 10 years.

Both Ağı Dağı and Camyurt have excellent exploration potential. At Ağı Dağı, an extension and exploration drill program has been designed to test along strike between the pits and follow up on other prospects on the project (Fire Tower, Ilhamur, and Ayi Tepe). At Camyurt an infill and exploration drilling program has been designed to both upgrade and grow the existing mineral resource base.

El Chanate

El Chanate's mineral reserves decreased to 293,000 ounces reflecting mining depletion. El Chanate is a mature operation with two years of mining remaining. The operation will then transition to residual leaching and will continue to produce gold for up to another four years at substantially lower costs providing for significant free cash flow.

Lynn Lake

Limited exploration drilling was conducted at Lynn Lake in 2016 with the focus on environmental baseline studies and geotechnical drilling in support of the project description and feasibility study, the latter of which is expected in the third quarter of 2017.

Exploration activities are expected to increase at Lynn Lake in 2017 with a total of $4 million budgeted. The focus will primarily be drilling adjacent to known mineral resources at Gordon and MacLellan and on grassroots exploration over the larger greenstone belt.

Exploration on these zones commenced in the third quarter of 2016 with 11,733 metres drilled down dip and along strike of the MacLellan deposit. Results are pending but the geology intersected is similar to that in the ore body and therefore very encouraging.

Camyurt, Esperanza and Quartz Mountain

Measured and Indicated and Inferred mineral resources for the Esperanza, Quartz Mountain and Camyurt projects were unchanged from a year ago.

Cautionary Note to U.S. Investors - Mineral Reserve and Resource Estimates

All resource and reserve estimates included in this news release or documents referenced in this news release have been prepared in accordance with Canadian National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101") and the Canadian Institute of Mining, Metallurgy and Petroleum (the "CIM") - CIM Definition Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as amended (the "CIM Standards"). NI 43-101 is a rule developed by the Canadian Securities Administrators, which established standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. The terms "mineral reserve", "proven mineral reserve" and "probable mineral reserve" are Canadian mining terms as defined in accordance with NI 43-101 and the CIM Standards. These definitions differ materially from the definitions in SEC Industry Guide 7 ("SEC Industry Guide 7") under the United States Securities Act of 1933, as amended, and the Exchange Act. Under SEC Industry Guide 7 standards, a "final" or "bankable" feasibility study is required to report reserves, the three-year historical average price is used in any reserve or cash flow analysis to designate reserves and the primary environmental analysis or report must be filed with the appropriate governmental authority.

In addition, the terms "mineral resource", "measured mineral resource", "indicated mineral resource" and "inferred mineral resource" are defined in and required to be disclosed by NI 43-101 and the CIM Standards; however, these terms are not defined terms under SEC Industry Guide 7 and are normally not permitted to be used in reports and registration statements filed with the U.S. Securities and Exchange Commission (the "SEC"). Investors are cautioned not to assume that all or any part of mineral deposits in these categories will ever be converted into reserves. "Inferred mineral resources" have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, except in very limited circumstances. Investors are cautioned not to assume that all or any part of an inferred mineral resource exists or is economically or legally mineable. Disclosure of "contained ounces" in a resource is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers to report mineralization that does not constitute "reserves" by SEC standards as in place tonnage and grade without reference to unit measures.

Notes to Mineral Reserve and Resource Tables:

  • The Company's Mineral Reserves and Mineral Resource as at December 31, 2016 are classified in accordance with the Canadian Institute of Mining Metallurgy and Petroleum's "CIM Standards on Mineral Resources and Reserves, Definition and Guidelines" as per Canadian Securities Administrator's NI 43-101 requirements.
  • Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability.
  • Mineral Resources are exclusive of Mineral Reserves.
  • Mineral Reserve cut-off grade for the Mulatos Mine, the Cerro Pelon Pit, the La Yaqui Pit, the Kirazlı Pit and the Ağı Dağı Pit are determined as a net of process value of $0.10 per tonne for each model block
  • All Measured, Indicated and Inferred Mineral Resources are pit constrained with the exception of those outside the Mulatos Main Pits on the Mulatos property which have no economic restrictions and are tabulated by gold cut-off grade.
  • Mineral Reserve estimates assumed a gold price of $1,250 per ounce and Mineral Resource estimates assumed a gold price of $1,400 per ounce, except as follows: Lynn Lake Mineral Resources assumed a gold price of $1,550 per ounce with an assumption of the Canadian dollar at parity with the United States dollar. Metal prices, cutoff grades and metallurgical recoveries are set out in the table below.
  • El Chanate reserve ounces include a December 31, 2016 inventory 99,900 recoverable ounces in the heap leach pad
