Alamos Reports a 38% Increase in Measured and Indicated Mineral Resources and Replaces Mineral Reserves at Mulatos

Thursday, March 24, 2011

Alamos Reports a 38% Increase in Measured and Indicated Mineral Resources and Replaces Mineral Reserves at Mulatos06:00 EDT Thursday, March 24, 2011TORONTO, ONTARIO--(Marketwire - March 24, 2011) -(All amounts are in United States dollars unless stated otherwise)Alamos Gold Inc. (TSX:AGI) ("Alamos" or the "Company") reports mineral reserves and resources for the Mulatos Mine in Mexico and mineral resources for the Aği Daği and Kirazli projects in Turkey as of December 31, 2010.Highlights:Reported proven and probable mineral reserves 2.39 million ounces of gold at Mulatos, replacing mineral reserves mined-out in 2010. Increased measured and indicated mineral resources by 38% to 4.40 million ounces of gold. Reported inferred mineral resources of 0.92 million ounces of gold. Increased the projected life of the Mulatos High-Grade Mill to 2.4 years from 1.6 years based solely upon updated reserves at Escondida. Reported initial mineral reserves at San Carlos. This document should be read in conjunction with the tables presented at the end of this press release. All references to the Company's 2009 mineral reserves and resources are reported in the Company's 2009 Annual Information Form dated March 31, 2010, available on SEDAR (www.sedar.com).Mineral ReservesIn 2010, the Company successfully replaced mined-out mineral reserves at Mulatos with total proven and probable reserves of 2.39 million ounces of gold at year-end. The replacement of reserve ounces is attributable to the conversion of mineral resources at San Carlos, inclusion of additional drilling at Escondida, conversion of pit-contained mineral resources to mineral reserves as a result of closer-spaced drilling, and using an $875 per ounce gold price assumption compared to $800 in 2009. A detailed summary of proven and probable mineral reserves for the Mulatos Mine as of December 31, 2010 is presented in Table 1 at the end of this press release.Based on the budgeted 2011 average throughput rate at the Mulatos Mine of 15,700 tonnes per day ("tpd") and a projected 500 tpd rate for the Mulatos High-Grade Mill, the Mulatos Mine has an overall expected mine life of approximately 9 years as of December 31, 2010. The life-of-mine waste-to-ore ratios as of December 31, 2010 for the Mulatos Mine and nearby satellite deposits are summarized in Table 2 at the end of this press release.Mineral ResourcesGlobally, the Company's measured and indicated mineral resources, which are reported exclusive of mineral reserves, increased 38% to 4.40 million ounces as of December 31, 2010 compared to the pro forma December 31, 2009 mineral resources (which includes the Aği Daği and Kirazli projects that were acquired on January 6, 2010). Over the same period, the Company's inferred mineral resources decreased to 0.92 million ounces as a result of the conversion of inferred mineral resources to the measured and indicated mineral resource categories. Mulatos Measured and indicated mineral resources at Mulatos, which are reported at a 0.5 grams of gold per tonne of ore ("g/t Au") cut-off, increased 47% to 2.75 million ounces and inferred resources decreased to 0.51 million ounces at December 31, 2010 compared to the prior year. The increase in measured and indicated mineral resources and the decrease of inferred mineral resources is primarily attributable to the conversion of the inferred mineral resources into the measured and indicated categories. The reported mineral resources also benefitted from the delineation of new resources through infill drilling and extension drilling.A detailed summary of measured and indicated mineral resources and inferred mineral resources for Mulatos are presented in tables 3 and 4 at the end of this release, respectively.A map detailing the current and 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. Aği Daği and Kirazli Indicated mineral resources at Aği Daği and Kirazli, which are reported at a 0.2 g/t Au cut-off, increased 26% to 1.65 million ounces and inferred mineral resources decreased to 0.42 million ounces compared to the March 2010 Preliminary Economic Assessment for these projects. The increase in indicated mineral resources and the decrease in inferred mineral resources are a result of the conversion of inferred mineral resources into the indicated category. The reported mineral resources also benefitted from the delineation of new resources at both Aği Daği and Kirazli through infill drilling.Detailed summaries of the indicated mineral resources for Aği Daği and Kirazli are presented in tables 5 and 6 at the end of this release, respectively. Inferred mineral resources for Aği Daği and Kirazli are presented in tables 7 and 8 at the end of this release, respectively. Figures 3 and 4 provide the location of mineral resource areas for Aği Daği and Kirazli projects in Turkey, respectively.Additionally, the Company is currently completing a preliminary feasibility study for the Aği Daği and Kirazli projects that will include updated mineral resource estimates for both projects to account for additional drilling carried out in late 2010 and early 2011.Qualified PersonsThe independent Qualified Person for the National Instrument 43-101 compliant mineral reserve estimate is Herb Welhener, Vice President of Independent Mining Consultants Inc. of Tucson, Arizona, working in conjunction with the Company's exploration and operations staff.
