OUTLOOK

Minera Juanicipio

In the six months ended June 30, 2012, Minera Juanicipio completed 13,762 metres of drilling designed to convert inferred mineral resources to indicated mineral resources on the Valdecañas Vein and delineate the high grade ore shoot emerging on the Juanicipio Vein. Additional drilling was also targeted on the Las Venadas vein and on searching for the next vein. Currently, eight drills continue in operation on the property.

On June 14, 2012, MAG announced the results of an updated National Instrument 43-101 ("NI 43-101") compliant Preliminary Economic Assessment for the Juanicipio Project. The Updated Preliminary Economic Assessment was commissioned by Minera Juanicipio (owned 44% by MAG and 56% by Fresnillo) and was carried out by AMC Mining Consultants (Canada) Ltd. (the "AMC Study") (see News Release dated June 14, 2012). A National Instrument 43-101 technical report documenting the economic assessment was filed on SEDAR on July 16, 2012. The AMC Study is expected to provide an important catalyst for Minera Juanicipio and open a pathway for the next step in its development. It is anticipated that the 2012 Minera Juanicipio budget will be reviewed and amended to reflect the recommendations in the AMC Study.

Cinco de Mayo

The Company originally expected to expend $3.5 million in 2012 at Cinco de Mayo (including Pozo Seco and Jose Manto), representing 15,000 metres of drilling targeted at delineating the mineralized corridor between Jose Manto and Cinco Ridge. As current year results have continued to demonstrate continuity of massive sulphide mineralization in the 'Bridge Zone' along the Jose Manto-Cinco Ridge corridor, and with the significance of hole CM12-431 and the new Pegaso Zone (see Press Release dated July 18, 2012), the Company has since revised its expectations and made plans to expend a total of $9.6 million in 2012. Actual expenditures to June 30, 2012 totaled $5,990,731 and further work in 2012 will go towards completing a Dimensional Seismic survey, further drilling, completing a first resource estimate (expected by the end of the third quarter of 2012), and the initiation of a PEA for this property.

In addition, metallurgical test work on the Pozo Seco zone has indicated that recoveries of both molybdenum and gold are sufficient to warrant the commencement of a PEA, and MAG has engaged RPA and Samuel Engineering to carry out a Preliminary Economic Assessment which will be completed early in the fourth quarter of 2012.
