VANCOUVER, BRITISH COLUMBIA–(Marketwire – April 1, 2011) – MAG Silver Corp. (TSX:MAG)(NYSE Amex:MVG) (“MAG” or the “Company”) announces the Company’s audited financial results for the year ended December 31, 2010. For complete details of the Annual Financial Statements for the year ended December 31, 2010 and related Management’s Discussion and Analysis, please see the Company’s filings on SEDAR (www.sedar.com) or on EDGAR (www.sec.gov). All amounts herein are reported in Canadian dollars unless otherwise specified.

At December 31, 2010, the Company had working capital of $40,478,028, including cash on hand of $39,825,071. The Company completed a brokered private placement financing that closed on May 18, 2010, whereby the Company issued 4,603,500 common shares of the Company at a price of $7.65 per share for gross and net proceeds of $35,216,775 and $33,148,722, respectively. 


  • In December 2010, the Company announced an independent updated mineral resource estimate for the Juanicipio Property made by Scott Wilson Roscoe Postle Associates Inc. (“Scott Wilson RPA”). Total (100%) Indicated resources on the Juanicipio property now stand at 110.8 million ounces of silver, 321 thousand ounces of gold, and 624 million pounds of lead and zinc. Total (100%) Inferred resources on the Juanicipio Property now stand at 93.3 million ounces of silver, 387 thousand ounces of gold, and 726 million pounds of lead and zinc. The resource calculation also included a first resource estimate for the Juanicipio Vein, the second significant vein on the property. It is estimated to contain an inferred 260,000 tonnes grading 553 grams per tonne (“g/t”) silver (16.1 ounces per ton (“opt”)) and 4.37 g/t gold for almost 5.2 million ounces of silver and 40,000 ounces of gold.

  • In July of 2010, Minera Juanicipio S.A. de C.V (“Minera Juanicipio”), a 56%/44% joint venture between Fresnillo plc (“Fresnillo”) and MAG, engaged AMC Mining Consultants (Canada) Ltd (“AMC”) to undertake a prefeasibility study for the development of a ‘standalone’ underground silver mine on the Valdecañas Vein. During the preparation phase of the ‘standalone’ prefeasibility study, it became apparent that a realistic and practical mine plan could not be properly proposed or designed if it was only to include or be based on Indicated Resources, as required by Canadian National Instrument 43-101 (“NI 43-101”). In order to better serve the objectives of the Juanicipio joint venture, and in keeping with practices employed by Fresnillo, AMC has been mandated by the Technical Committee of Minera Juanicipio to include both Inferred and Indicated resources in this independent “standalone” mine development study. Subject the consent of AMC, the study will be issued by the Company in Canada as an updated preliminary economic assessment in compliance with NI 43-101, and be titled as a “Scoping Study Update, 2011” (“2011 Study Update”). A preliminary working draft of the 2011 Study Update was received by Minera Juanicipio in late February 2011. A revised draft of the study reflecting joint input from both Fresnillo and MAG, is expected early in the second quarter of 2011, and a final report shortly thereafter.

  • Subsequent to year end, the Board of Minera Juanicipio approved a preliminary 2011 budget of US$4.5 million to cover drilling proposed for exploration, and agreed to revisit the budget after reviewing the recommendations contained in the 2011 Study Update.


  • The Company announced the release of an initial mineral resource estimate for the Pozo Seco molybdenum-gold discovery prepared by Scott Wilson RPA. At a cut-off grade of 0.022% molybdenum, the Indicated mineral resources are estimated at 29.1 million tonnes, grading 0.147% molybdenum and 0.25 g/t gold, containing 94.0 million pounds molybdenum and 230,000 ounces gold. The Inferred mineral resources are estimated at 23.4 million tonnes grading 0.103% molybdenum and 0.17 g/t gold, containing 53.2 million pounds molybdenum and 129,000 ounces gold.

  • Metallurgical testing began in May 2010 to assess the recoverability of both molybdenum and gold in the Pozo Seco deposit and is ongoing. Gravitational separation, leaching and flotation techniques are being tested. Upon completing the test work, and subject to positive metallurgical results, the Company will proceed to complete a Preliminary Economic Assessment (“PEA”) during the year.

  • During the year ended December 31, 2010, approximately 67,417 metres were drilled in 175 holes. Subsequent to the year ended December 31, 2010, the Company announced high-grade, silver-rich sulphide and skarn-altered intrusion intercepts from on-going exploration drilling in the north-western part of the Cinco de Mayo property. The first two holes into the previously undrilled “Polaris East” area have hit what appears to be the same set of sheeted sulphide replacement veins. The principal vein in Hole CM11-343 is 2.81 metres wide and grades 483 g/t (14.1 opt) silver, 0.22 g/t gold, 4.52% lead and 11.74% zinc. The same vein is seen in Hole CM11-335 and is 1.42 metres wide reporting 287 g/t (8.3 opt) silver, 0.24 g/t gold, 2.67% lead and 1.40% zinc, with the interval from 527.11 to 527.68 (0.57 metres) carrying 639 g/t (18.6 opt) silver, 0.35 g/t gold, 5.42% lead and 2.35% zinc. The intercepts are approximately 50 metres apart. These important results and host geology point to Polaris as an important target area. The Company’s immediate exploration efforts at Cinco De Mayo will focus in this area in 2011. 


In 2009, during Fresnillo’s hostile bid attempt, MAG initiated arbitration proceedings with the International Court of Arbitration of the International Chamber of Commerce pursuant to the dispute resolution provisions contained in the Minera Juanicipio Shareholders Agreement. MAG is seeking a ruling as to whether or not Fresnillo may acquire or attempt to acquire control of MAG without the consent of MAG’s board in breach of the standstill provisions contained in the Shareholders Agreement and relief in relation to other alleged violations by Fresnillo as operator under the Shareholders Agreement, including damages and other orders arising from Fresnillo’s alleged failure to advance development on the Juanicipio property at an appropriate pace consistent with the standards imposed by the Shareholders Agreement. Early in 2010, an arbitral tribunal was established and in October 2010 a hearing was held in Mexico City. Final written legal submissions were delivered to the arbitral tribunal in December 2010. The Company is now awaiting a tribunal decision which is expected to be issued by April 30, 2011. Results of litigation are inherently uncertain and there can be no assurances as to the final outcome.


The Company has approved a preliminary 2011 exploration budget totalling $10.0 million. Of this amount $2.3 million is allotted for the Company’s 44% share of Minera Juanicipio’s US$4.5 million 2011 exploration budget plus other costs related to the Company’s direct oversight of the project. The remaining $7.7 million is earmarked for MAG’s 100% owned properties, including Cinco de Mayo/Pozo Seco ($2.8 million) the Lagartos properties ($1.6 million), the Company’s two optioned properties, Esperanza and Mojina ($1.9 million combined) and the balance of $1.4 million on other projects. The Company also expects to approve additional expenditures in 2011 for surface right purchases and possibly for the initiation of underground development at Juanicipio.


The Company’s net loss for the year amounted to $12,283,370 ($0.24 per share) for the year ended December 31, 2010 as compared to $13,490,210 ($0.27 per share) in 2009. The decreased loss in 2010 compared to 2009 was primarily due to lower mineral property cost write offs. In 2010 $2,558,366 in property costs were written for the Salemex and Camino Duro projects. Property costs written off in 2009 totalled $3,718,518. The net loss for 2010 includes a non-cash charge for stock compensation expense of $3,091,995 compared to $1,804,465 in 2009. Legal fees incurred during 2010 of $3,196,063 (2009 – $3,048,507) continued to be high as a result of the ongoing costs related to the arbitration proceedings against Fresnillo. Shareholder relations expenses of $327,265 decreased in 2010 compared to $714,809 in 2009 when MAG was exposed to substantial costs in shareholder communications, particularly related to the take-over defense and the OSC proceedings as a result of Fresnillo’s intended hostile bid. Accounting and audit fees for the year of $687,782 increased from $456,761 in 2009, as the Company incurred substantial advisory costs on tax and strategic planning in Mexico.

Accounts receivable at December 31, 2010 totalled $2,208,533 (2009: $2,042,634) and were comprised primarily of value added taxes repayable to the Company by the Government of Mexico. Current liabilities at December 31, 2010 amounted to $2,320,261 (2009: $1,076,606) and are attributable primarily to accrued legal and exploration (drilling) expenses. During the year ended December 31, 2010, the Company incurred $634,580 in property acquisition costs (2009: $2,156,057), $13,446,792 in exploration costs (2009: $14,389,336), and $3,033,635 for the Company’s 44% share of Juanicipio property costs (2009: $1,215,328). Combined 2010 expenditures of $17,115,007 (2009: $17,760,721) exceeded the 2010 final exploration budget of $15 million by approximately $2.1 million, primarily attributable Cinco de Mayo where drilling results justified a higher than budgeted rate of exploration drilling.
