Alamos Gold Inc. Increases Reserves on Its 100% Owned Mulatos Deposit in Sonora, Mexico

TORONTO, ONTARIO--(CCNMatthews - March 29, 2007) - Alamos Gold Inc. (TSX:AGI) ("Alamos" or the "Company") reports an increase in mineral reserves at its Mulatos deposit, in Sonora, Mexico. The updated mineral reserve estimate was calculated as at December 31, 2006 using a price of $500 per ounce of gold, and indicates proven and probable reserves of 2.1 million contained ounces. This reflects a 7% increase from the mineral reserves for the Estrella Pit reported in the Company's Feasibility Study dated June 17, 2004 of 1.92 million contained ounces. The updated mineral reserve estimate incorporates the Estrella, Mina Vieja, El Salto and Escondida areas.

The Company's exploration and development program has been successful in adding reserves to areas outside of the existing Estrella Pit. The Company anticipates growing its reserve base in 2007 and 2008 as the results of drilling at the Gap and El Victor areas are incorporated into its global mineral reserve.

Proven and probable reserves are summarized in the table below as at
December 31, 2006:

At December 31, 2006

1. Unless otherwise noted, the Company's reserves are estimated using
appropriate cut-off grades ranging from 0.4 g/t Au to 0.9 g/t Au
derived using an estimated gold price of US$500 per ounce. Reserves are
estimated using projected life-of-mine operating costs and gold
recovery assumptions.
2. The Company's reserves as at December 31, 2006 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 National Instrument 43-101 ("NI 43-101") requirements.


Current mining operations at the Mulatos deposit are focused on the Estrella Pit. The table below presents reserves in the Estrella Pit as at December 31, 2006 compared to the original 2004 Feasibility Study estimate:

Proven and Probable At December 31, 2006 2004 Feasibility Study
Estrella Pit Tonnes Grade Ounces Tonnes Grade Ounces
(000) (g/t Au) (000) (000) (g/t Au) (000)

Oxide 1,871 0.90 54 2,802 1.12 101
Silicified Mixed 7,975 1.64 420 7,863 1.65 417

Silicified Sulfide 13,981 1.81 811 16,037 1.81 933
Non-Silicified Sulfide 7,048 1.52 344 8,456 1.48 401
Total 31,900 1.64 1,682 36,367 1.64 1,913

Mineral reserves in the Estrella Pit were 31,900,000 tonnes at a grade of 1.64 g/t Au for total contained ounces of 1,682,000 as at December 31, 2006. The 12% reduction in contained ounces between the 2004 Feasibility Study and as at December 31, 2006 is the result of a combination of the following factors:

- A total of 268,000 contained ounces was mined from the Estrella Pit in the period from the start of mining operations in the third quarter of 2005 to December 31, 2006.

- Mineral reserves were estimated at December 31, 2006 using a gold price of US$500 per ounce as compared to US$350 per ounce used in calculating the reserves reported in the 2004 Feasibility Study.

- Mine operating costs and royalty costs used in the calculation of mineral reserves as at December 31, 2006 have increased from the assumptions used in the 2004 Feasibility Study estimate.


Mineral reserves in the Escondida project area contributed 232,000 contained ounces to the mineral reserve estimate as at December 31, 2006. The majority of these ounces (141,000) are derived from the Escondida High Grade Zone, where the Company believes that the grade used in the reserve calculation understates the actual grade due to coarse gold sampling issues. Further sampling tests and analysis are currently underway in order to report a more accurate grade for this area.

El Salto - Mina Vieja

The El Salto - Mina Vieja area contributed 142,000 contained ounces to the mineral reserve estimate as at December 31, 2006. The 2004 Feasibility Study reserve estimate did not include the El Salto-Mina Vieja area.


The Company is expected to announce revised resources at the El Victor project area in the second half of 2007 and is currently drilling the Gap area. The Company anticipates significant future increases in mineral reserves and resources from the El Victor, Gap and San Carlos areas within the Mulatos Deposit.

Qualified Person(s)

The independent Qualified Person for the NI 43-101 compliant reserve estimate is Herb Welhener, Vice President of Independent Mining Consultants of Tucson, Arizona working in conjunction with the Company's exploration and operations staff.

Keith Blair, Manager of Applied Geoscience LLC of Reno, Nevada, prepared the resource report combining the Escondida deposit resource models and previously released 2004 Feasibility Study and El Salto/Mina Vieja resource models prepared by Mike Lechner, President of Resource Modeling Inc. of Tucson, Arizona. Both Mr. Blair and Mr. Lechner are recognized as Qualified Persons according to the requirements of NI 43-101. Details of the individual resource estimates are provided in previous releases of February 1, 2007, November 7, 2005, and January 21, 2004. Resource models were generated for the original deposit topography, and for the portion of the deposit remaining below pit topography at the end of 2006.

The exploration work in the Escondida, El Salto, Mina Vieja, San Carlos, and El Victor areas was conducted under the direction of Ken Balleweg, P. Geol, BSc. Geological Engineering, M.S. Geology, Alamos' Vice President of Exploration and a Qualified Person as defined by NI 43-101. Drilling and analytical methods for each individual resource area are outlined in the releases for each area and the 2004 Feasibility Study.
