Alamos Replaces Reserves at Mulatos and Updates Mineral Resources

06:00 EDT Monday, April 01, 2013

TORONTO, ONTARIO--(Marketwire - April 1, 2013) -

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

Alamos Gold Inc. (TSX:AGI) (NYSE:AGI) ("Alamos" or the "Company") today reported mineral reserves and mineral resources for the Mulatos Mine and nearby satellite deposits in Mexico, and mineral resources for the Ağı Dağı, Kirazlı and Çamyurt projects in Turkey, as of December 31, 2012.

Highlights

  • Proven and Probable mineral reserves of 2.37 million ounces of gold at Mulatos, replacing mineral reserves mined-out in 2012.
  • Increased Measured and Indicated mineral resources by 2% to 5.08 million ounces of gold at a mix of cut-off grades, depending on the deposit.
  • Inferred mineral resources of 1.52 million ounces of gold at a mix of cut-off grades, depending on the deposit.

The mineral resource estimate for the Company's Turkish projects includes the June 2012 initial Inferred mineral resource estimate at Çamyurt. The Company plans to release an updated mineral resource for Çamyurt separately in the second quarter of 2013 in order to incorporate all existing drill results.

Mineral Reserves

In 2012, the Company successfully replaced mined-out mineral reserves at Mulatos, with total proven and probable reserves of 2.37 million ounces of gold at year-end. The replacement of reserve ounces is attributable to the addition of new ounces at El Victor, conversion of pit-contained mineral resources to mineral reserves, and the use of a $1,400 per ounce gold price assumption compared to $1,150 in 2011. A detailed summary of Proven and Probable mineral reserves for the Mulatos Mine as of December 31, 2012 is presented in Table 1 at the end of this press release.

Based on the 2013 budgeted average throughput rate at the Mulatos Mine of 17,000 tonnes per day ("tpd") and a projected 500 tpd rate for the high grade mill, the overall expected life of the Mulatos Mine remains at approximately nine years as of December 31, 2012. The life-of-mine waste-to-ore ratios as of December 31, 2012 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 5.08 million ounces at a mix of cut-off grades, as of December 31, 2012. Reflecting the inclusion of the initial mineral resource estimate from the Çamyurt project as reported on June 28, 2012, the Company's Inferred mineral resources as of December 31, 2012 total 1.52 million ounces. Detailed summaries of Alamos Gold's Global Measured and Indicated, and Inferred mineral resources as of December 31, 2012 are presented in Tables 3 and 4, respectively, at the end of this press release.

Mulatos Mine (Mexico)

Measured and Indicated mineral resources at the Mulatos Mine and its satellite deposits decreased slightly to 2.64 million ounces and Inferred mineral resources also decreased slightly to 0.50 million ounces as of December 31, 2012 compared to the prior year. The mineral resources are reported at a 0.5 g/t Au cut-off at Mulatos and San Carlos, at a 2.5 g/t Au cut-off for the San Carlos underground resources, and at a 0.3 g/t Au cut-off at El Realito and Carricito areas. The slight decrease in Measured, Indicated, and Inferred mineral resources is primarily attributable to the conversion of mineral resources into Proven and Probable mineral reserves.

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. The reported mineral resources also benefitted from the delineation of new resources through infill drilling and extension drilling, as well as the initial reporting of mineral resources for the San Carlos underground (Tables 7 and 8), Carricito (Tables 9 and 10) and El Realito (Tables 11 and 12) project areas.

A map detailing the planned Mulatos Pit area is presented in Figure 1 at the end of this press release. The locations of the Cerro Pelon and La Yaqui mineral reserve areas, as well as other regional targets within the Mulatos District, are shown in Figure 2 at the end of this press release.

Ağı Dağı and Kirazlı (Turkey)

Measured and Indicated mineral resources at Ağı Dağı and Kirazlı, which are reported at a 0.2 g/t Au cut-off, increased 9.9% to 2.44 million ounces of gold, as compared to the mineral resources reported in December 2011. In addition, Measured and Indicated mineral resources of silver increased 16.9% to 19.72 million ounces compared to the resource update in December 2011. The increase in Measured and Indicated mineral resources is a result of a combination of infill and resource expansion drilling programs undertaken in 2012, resulting in the conversion of Inferred mineral resources to the Indicated category.

Inferred mineral resources at Ağı Dağı, Kirazlı and Çamyurt, which are reported at a 0.2 g/t cut-off grade, contained 1.02 million ounces at year-end 2012, as compared to the 1.09 million ounces reported in the December 31, 2011 mineral resource statement (Ağı Dağı and Kirazlı) and June 28, 2012 press release (Çamyurt). The decrease of 6.4% was attributable to the conversion of some Inferred mineral resources at Ağı Dağı and Kirazlı to Measured and Indicated mineral resources. The Company expects to release an update on the resource estimate for Çamyurt in the second quarter of 2013 in order to include all 2012 drill results.

Detailed summaries of the Measured and Indicated, and Inferred mineral resources for Ağı Dağı are presented in Tables 13 and 14, respectively, at the end of this press release. The Measured and Indicated, and Inferred mineral resources for Kirazli are presented in Tables 15 and 16, respectively. Inferred mineral resources for Çamyurt are presented in Table 17, also presented at the end of the press release. Figure 3 provides the location in Turkey of mineral resource areas for the Ağı Dağı project and Figure 4 provides the location of the mineral resource area for the Çamyurt project. Figure 5 provides the location of the mineral resource area for the Kirazli project.

All statements other than statements of historical fact included in this release, including without limitation statements regarding forecast gold production, gold grades, recoveries, waste-to-ore ratios, total cash costs, potential mineralization and reserves, exploration results, and future plans and objectives of Alamos, are forward-looking statements that involve various risks and uncertainties. These forward-looking statements include, but are not limited to, statements with respect to mining and processing of mined ore, achieving projected recovery rates, anticipated production rates and mine life, operating efficiencies, costs and expenditures, changes in mineral resources and conversion of mineral resources to proven and probable reserves, and other information that is based on forecasts of future operational or financial results, estimates of amounts not yet determinable and assumptions of management.

Exploration results that include geophysics, sampling, and drill results on wide spacings may not be indicative of the occurrence of a mineral deposit. Such results do not provide assurance that further work will establish sufficient grade, continuity, metallurgical characteristics and economic potential to be classed as a category of mineral resource. A mineral resource that is classified as "inferred" or "indicated" has a great amount of uncertainty as to its existence and economic and legal feasibility. It cannot be assumed that any or part of an "indicated mineral resource" or "inferred mineral resource" will ever be upgraded to a higher category of resource. Investors are cautioned not to assume that all or any part of mineral deposits in these categories will ever be converted into proven and probable reserves.

Any statements that express or involve discussions with respect to predictions, expectations, beliefs, plans, projections, objectives, assumptions or future events or performance (often, but not always, using words or phrases such as "expects" or "does not expect", "is expected", "anticipates" or "does not anticipate", "plans", "estimates" or "intends", or stating that certain actions, events or results "may", "could", "would", "might" or "will" be taken, occur or be achieved) are not statements of historical fact and may be "forward-looking statements." Forward-looking statements are subject to a variety of risks and uncertainties that could cause actual events or results to differ from those reflected in the forward-looking statements.

There can be no assurance that forward-looking statements will prove to be accurate and actual results and future events could differ materially from those anticipated in such statements. Important factors that could cause actual results to differ materially from Alamos' expectations include, among others, risks related to international operations, the actual results of current exploration activities, conclusions of economic evaluations and changes in project parameters as plans continue to be refined as well as future prices of gold and silver, as well as those factors discussed in the section entitled "Risk Factors" in Alamos' Annual Information Form. Although Alamos has attempted to identify important factors that could cause actual results to differ materially, there may be other factors that cause results not to be as anticipated, estimated or intended. There can be no assurance that such statements will prove to be accurate as actual results and future events could differ materially from those anticipated in such statements. Accordingly, readers should not place undue reliance on forward-looking statements.

(1) The updated mineral resource estimate incorporates the Estrella, Escondida, Puerto del Aire, El Salto, Mina Vieja, El Victor, and San Carlos areas.
(2) In-pit measured and indicated mineral resource blocks are exclusive of pit-contained reserves.
(3) Measured and indicated and inferred mineral resources outside of the Mulatos Mine have no economic restrictions and are tabulated by gold cut-off grade.
(4) Underground resources are presented at a 2.5 g/t Au cut-off grade for the San Carlos area.
(5) Measured and indicated and inferred resources at Carricito and El Realito are pit-constrained, applying a $1,500/oz gold price, 55° pit slopes, and an $8.55/t operating cost.
(6) Mineral resources are not mineral reserves and do not have demonstrated economic viability.

Notes for Tables 13 & 14:
(1) Measured and indicated and inferred resources for the Ağı Dağı project, which includes the Baba, Ayitepe, Deli, and Fire Tower zones, are pit constrained with cut-off determined as a net of process value of $0.10 per tonne, for each model block. The determination was based on a US$1,500 per ounce gold price and a US$28.00 per ounce silver price, a December 2012 resource model, average pit slope angle of 38°, and estimated costs and recoveries based on the pre-feasibility study specifications. The resources were then tabulated by gold cut-off grade.
(2) Measured and indicated, and inferred resources for the Kirazli project, including Rockpile, are pit constrained with cut-off determined as a net of process value of $0.10 per tonne, for each model block. The determination was based on a US$1,500 per ounce gold price and a US$28.00 per ounce silver price, a December 2012 resource model, average pit slope angle of 38°, and estimated costs and recoveries based on the pre-feasibility study specifications. The resources were then tabulated by gold cut-off grade.
(3) Inferred resources for the Çamyurt project are pit-constrained, using a $1,250 per ounce gold price, a 60:1 Ag:Au value ratio (Au equivalent = Au + ((Ag/60) * Ag recovery)), an average pit slope angle of 45°, estimated costs based on the Pre-feasibility study, and recoveries for Au and Ag based on grade ranges. Only oxide and transition material were considered in the pit run. Please refer to the Company's June 28th, 2012 press release.
(4) Mineral resources are not mineral reserves and do not have demonstrated economic viability.
