For Calendar Year 2012, the Pallancata Mine produced (on a 100% basis) approximately 7.4 million ounces of silver (8.8 million ounces in Calendar Year 2011) and 26,231 ounces of gold (33,881 ounces in Calendar Year 2011). The Company’s 40% share of production for Calendar 2012 was approximately 3.0 million ounces of silver (3.5 million ounces in 2011) and 10,492 ounces of gold (13,553 ounces in 2011).

The decreases in gold and silver production for both the Current Quarter and Calendar Year 2012 compared to the respective previous periods are due primarily to a decrease in the grades of both silver and gold processed because (a) the mine experienced an increase in mining dilution due to the narrower veins being mined, and (b) the mine encountered production scheduling constraints which restricted mine development and backfill placement. These issues are currently being addressed by the mine operator.

IMZ anticipates that production from the Pallancata Mine for Calendar Year 2013 will be similar to 2012 at approximately 7.4 million ounces of silver and 26,000 ounces of gold, with approximately 3.0 million ounces of silver and 10,400 ounces of gold representing IMZ’s 40% share of anticipated 2013 production.

Operating Statistics for the Pallancata Mine (100% basis and IMZ 40% basis).

The Table below reports key production statistics for the Pallancata Mine for the Current Quarter (ended December 31, 2012) and Calendar Year 2012 (12 months ended December 31, 2012), together with the respective previous periods.

Note:
1. The reported head grades for silver and gold are based on the overall metallurgical balance for the process plant.

Production costs for both the Current Quarter and Calendar Year 2012 will be provided in a Company news release to be issued after the close of markets on February 14, 2013, together with disclosure of the financial results for the Current Quarter.

With respect to the financial results for the Current Quarter, as a result of lower income from Pallancata and a further write-down of approximately US$14.5 million in the carrying value of the Ecuador assets (see the Company’s November 21, 2012 news release), the Company expects to report a net loss for the Current Quarter. This loss remains to be fully quantified but at this time it is anticipated to be in the US$9 million to $10 million range, compared to net income after tax of US$11.1 million for the quarter ended December 31, 2011. Net income after tax for the fiscal 6-month period ended December 31, 2012 is expected to be close to break-even compared to net income after tax of US$26.3 million for the fiscal 6-month period ended December 31, 2011.

Inmaculada Project Update

At the Company’s 40%-owned Inmaculada gold-silver project in Peru (Hochschild 60%-owned and operator), a loan arrangement on favorable terms with a syndicate of Peruvian banks is currently being negotiated by Minera Suyamarca S.A.C.

The amount and terms of this loan are expected to be finalized with the banks by the end of March 2013 and will be announced to the market at that time. It is anticipated that Inmaculada will commence production in the second half of 2014 (See IMZ new release dated November 26, 2012 for more details).
