Alamos Gold Inc. (TSX:AGI)(NYSE:AGI) ("Alamos" or the "Company") today reported its updated mineral reserves and resources as of December 31, 2014. For a detailed summary of mineral reserves and resources by project, refer to the table below.

Highlights

• Proven and Probable mineral reserves at Mulatos of 1.73 million ounces of gold, which at current throughput rates, implies a remaining reserve life of approximately seven years
• Total Mulatos open pit, heap leach mineral reserve grade (including satellite deposits), increased 3% to 1.07 grams per tonne of gold ("g/t Au"), 34% above the 2015 budgeted open pit, heap leach grade
• Total Mulatos open pit, heap leach mineral reserves decreased 12% in terms of ounces, primarily reflecting depletion. Limited exploration targeting open pit mineral reserves was conducted in 2014. This will be a renewed exploration focus in 2015
• Increased Measured and Indicated mineral resources by 3% to 6.85 million ounces of gold at various cut-off grades, driven by a 13% or 0.32 million ounce increase at the Mulatos open pit
• Sold the El Realito concessions, a non-core portion of the large exploration package at Mulatos, for proceeds of US$7 million cash and a 2% net smelter returns royalty
• Commenced exploration activities at the Cerro Pelon satellite deposit

Mineral Reserves

Proven and Probable mineral reserves at Mulatos decreased 15% to 1.73 million ounces at December 31, 2014, primarily reflecting mining depletion. The focus of the 2014 exploration program was on production drilling at San Carlos underground to further define the 2015 production model. Limited drilling was conducted targeting open pit mineral reserves and resources within the Mulatos open pit in 2014. However, the Company has budgeted $17 million in exploration spending at Mulatos in 2015 focusing on San Carlos and a renewed emphasis on delineating additional open pit mineral reserves within the Mulatos open pit and higher grade Cerro Pelon and La Yaqui satellite deposits. A $1,250 per ounce gold price assumption was used in estimating the 2014 mineral reserves, unchanged from 2013. A detailed summary of Proven and Probable mineral reserves for the Mulatos Mine as of December 31, 2014 is presented in Table 1 at the end of this press release.

Open Pit Mineral Reserves

Mulatos open pit, heap leach mineral reserves (including the Mulatos Mine, stockpiles, Cerro Pelon and La Yaqui) decreased 12% from 2013 reflecting mining depletion. The mineral reserve grade increased slightly to 1.07 g/t Au, 34% above the 2015 budgeted grade for open pit, heap leach production. The mineral reserve grade of the Mulatos Mine, the primary source of open pit, heap leach production, increased slightly to 0.94 g/t Au, 18% above the 2015 budgeted grade. Open pit, heap leach grades are expected to rebound to approximately 0.9 g/t Au in 2016, driving costs lower.

The mineral reserve estimates for the Cerro Pelon and La Yaqui satellite deposits were largely unchanged with the mineral reserve grade at Cerro Pelon increasing 2% to 1.67 g/t Au. With the average grade of the two satellite deposits of 1.64 g/t Au being more than double the 2015 budgeted heap leach grade, these deposits are expected to add low cost production growth at Mulatos starting from La Yaqui late in 2016. Both deposits and their surrounding land packages possess significant exploration potential and will be a focus of the 2015 exploration program having last been drilled in 2009. At La Yaqui, condemnation drilling is currently underway after encountering surface mineralization on the northern edge of the planned leach pad location. Having closed the agreement to acquire the surface rights at Cerro Pelon earlier this month, the Company is currently mobilizing rigs to test the extent of the mineralization with further potential recently identified to the southeast, the north and east of known mineral reserves. Drilling will first target a possible 200 metre ("m") strike extension to the deposit in a south-easterly direction and another 100 m of (previously untested) strike extension between two of the four distinct breccia zones identified to date.

Underground Mineral Reserves

Mulatos underground mineral reserves decreased 33% to 146,400 ounces reflecting mining depletion at Escondida Deep and San Carlos, a decrease in the mill recovery assumption to 75% (consistent with the 2015 budget), and the reclassification of mineral reserves to mineral resources. Approximately 36,100 ounces previously classified as mineral reserves were reclassified to the Measured and Indicated and Inferred mineral resource categories. This is largely a classification issue with the majority of these reclassified ounces located in the central part of the deposit, which was not a focus of the 2014 exploration program.

The 2014 exploration program at San Carlos was focused on infill and production drilling of the western portion of the deposit which is to be mined in 2015. The program was successful in developing a better understanding of the ore body and further defining the 2015 mine plan; however, this also highlighted the need for a similar level of definition drilling across the remainder of the deposit. As a result, the Company has adopted a more conservative approach to estimating the mineral reserves at San Carlos and shifted some mineral reserves into mineral resources. With further drilling in these zones the Company is confident a large portion of the reclassified ounces can be converted back to mineral reserves and will be a focus of the 2015 exploration program.

The Company believes there is potential to significantly extend the underground mine life at San Carlos and has budgeted $5.7m for exploration in 2015 with the focus on adding to the mineral resource base and converting existing mineral resources to mineral reserves. Approximately 12,000 ounces of Inferred mineral resources are located in very close proximity to the current mine plan and will be targeted as part of the 2015 exploration program. The Company expects to mine a number of these ounces in conjunction with the 2015 and 2016 mine plan. East of the immediate production area, the ore body has been shown to extend for at least another 650 m along strike through the Central and Eastern Zones. Drilling in 2014 encountered very promising high-grade intercepts in these zones and further drilling is required in order to fully quantify the potential of this area. Additional strike length may exist even further east across a post-mineral fault.

Recent highlight intercepts from the 2014 exploration program at San Carlos are as follows:

Western Production Area:

• 87.57 g/t Au over 4.6 m, including 259.00 g/t over 1.5 m (14SC254)
• 35.32 g/t Au over 12.2 m (14SC270)
• 43.70 g/t Au over 19.8 m (14SC275)
• 55.67 g/t Au over 9.2 m and 48.94 g/t over 9.1 m (14SC298)
• 50.34 g/t Au over 29.0 m (14SC339)
• 347.65 g/t Au over 2.0 m (14SC358)
• 68.18 g/t Au over 12.20 m (14SC362)

Central and Eastern Exploration Area:

• 9.18 g/t Au over 7.6 m (14SC313)
• 29.58 g/t Au over 3.1 m (14SC330)
• 10.36 g/t Au over 6.0 m and 15.82 g/t over 3.0 m (14SC363)
• 19.54 g/t Au over 4.0 m (14SC364)
• 56.60 g/t Au over 1.5 m (14SC369)
• 26.99 g/t Au over 3.0 m (14SC370)

Further highlights from recent drilling completed at San Carlos underground are presented in Table 18 at the end of this release.

Based on the 2015 budgeted average throughput rate at the Mulatos Mine of 17,300 tonnes per day ("tpd") and a projected 550 tpd rate for the high grade mill, the remaining mineral reserve life of the Mulatos Mine is approximately seven years as of December 31, 2014. The life-of-mine waste-to-ore ratios as of December 31, 2014 for the Mulatos Mine and nearby satellite deposits are summarized in Table 2 at the end of this press release.

Mineral Resources

Globally, the Company's Measured and Indicated mineral resources, which are reported exclusive of mineral reserves, are 6.85 million ounces at various cut-off grades, as of December 31, 2014. This represents a 3% increase in ounces and 4% increase in grade from 2013.

Inferred mineral resources as of December 31, 2014 of 3.60 million ounces decreased 2% relative to 2013 with the grade unchanged. In 2014, the Company applied a$1,400 per ounce gold price assumption for estimating mineral resources which was unchanged from 2013 for Mulatos and the Company's Turkish projects, and down from $1,600 per ounce for the Esperanza Gold Project. Detailed summaries of the Company's Global Measured and Indicated, and Inferred mineral resources as ofDecember 31, 2014 are presented in Tables 3 and 4, respectively, at the end of this press release.

Mulatos Mine (Mexico)

Open pit Measured and Indicated mineral resources at the Mulatos Mine and its satellite deposits increased 13%, or 0.32 million ounces to 2.71 million ounces with the grade also increasing 4% to 1.06 g/t Au. Open pit Inferred mineral resources decreased 87,200 ounces to 232,200 ounces, as of December 31, 2014, reflecting the conversion of Inferred mineral resources to Measured and Indicated mineral resources.

Underground Measured and Indicated mineral resources at San Carlos decreased 32,300 ounces to 91,500 ounces. This decrease was more than offset by a 57,300 ounce increase in Inferred mineral resources at San Carlos (refer to Tables 7 and 8).

The mineral resources are reported at a 0.5 g/t Au cut-off at Mulatos and at a 2.5 g/t Au cut-off for underground resources. Detailed summaries of Measured and Indicated mineral resources and Inferred mineral resources for Mulatos are presented in Tables 5 and 6, respectively, at the end of this press release.

Agi Dagi, Kirazli, and Çamyurt (Turkey)

Measured and Indicated mineral resources at Agi Dagi, Kirazli and Çamyurt, which are reported at a 0.2 g/t Au cut-off, increased 1% or 41,000 ounces to 2.96 million ounces of gold and 24.5 million ounces of silver, as compared to December 31, 2013. This reflected changes to the pit design including the use of slightly steeper slopes.

Inferred mineral resources at Agi Dagi, Kirazli and Çamyurt also increased 39,800 ounces to 437,800 ounces at year end 2014.

Detailed summaries of the Measured and Indicated, and Inferred mineral resources for Agi Dagi are presented in Tables 9 and 10. The Measured and Indicated, and Inferred mineral resources for Kirazli are presented in Tables 11 and 12. Measured and Indicated, and Inferred mineral resources for Çamyurt are presented in Tables 13 and 14.

Esperanza Gold Project (Mexico)

Measured and Indicated mineral resources at the Esperanza Gold Project, which are reported at a 0.4 g/t Au cut-off grade, decreased 12% to 1.08 million ounces of gold and 8.9 million ounces of silver as at year end 2014. This reflects a lower gold price assumption of $1,400 per ounce, from $1,600 per ounce, resulting in a smaller but much higher quality mineral resource with the grade increasing 20% to 0.98 g/t Au.

Detailed summaries of the Measured and Indicated, and Inferred mineral resources for Esperanza Gold project are presented in Tables 15 and 16, respectively, at the end of this press release.

Quartz Mountain Property (USA)

Inferred mineral resources at the Quartz Mountain Property, which are reported at a 0.21 g/t Au cut-off for oxide and 0.58 g/t Au for sulphide, contained 2.85 million ounces at year-end 2014, unchanged from 2013. This includes oxide mineral resources of 1.30 million ounces and sulphide mineral resources of 1.55 million ounces. The Company is currently conducting an 8,000 m drill program with the dual objective of validating the existing resource and testing the new geological model. The program is expected to continue to mid-year 2015.

A detailed summary of the Inferred mineral resources for Quartz Mountain are presented in Table 17.

Sale of El Realito Concessions

Earlier this month, the Company sold the El Realito exploration concessions, a small portion of its large exploration package at Mulatos, to Agnico Eagle Mines Limited ("Agnico") for proceeds of US$7 million cash and a 2% net smelter returns ("NSR") royalty. The El Realito exploration concessions total approximately 6% of the Company's large exploration package of 30,325 hectares. The concessions are located in the north-west corner of the Mulatos District, approximately 14 kilometers from the existing Mulatos Mine and processing facilities and adjacent to Agnico's La India mine. As part of the agreement, Agnico has the option of reducing the 2% NSR royalty to 1% through an additional payment of $4 million.
