Operations Update

Year End 2011

Agitated Leach Plant

Following the appointment of the Management Team, the Company began a review of the ALP to identify ongoing production inefficiencies. As a result, late in the fourth quarter the Company stopped its commissioning efforts to commence modifications to the crushing and screening circuits to enable the plant to operate at 50% capacity. These modifications were completed in February 2012 with the commissioning phase expected to be completed by the end of March. In addition, detailed engineering has started in the crushing and screening circuits to increase throughput to 100% capacity. The implementation and construction phase of this project are scheduled to take place in the second half of 2012.

Second Quarter 2011

Agitated Leach Plant

The agitated leach plant ("ALP") was modified in late 2010 to handle variable ore types encountered at Aguas Blancas. Modifications to the crushing and screening circuit were successful in providing ore to the leach circuit. Trial runs on the leach circuit indicated that there were modifications required to this section of the plant which have been carried out. Work on the scrubbing circuit remains to be completed. The plant is currently in commissioning and ramp up to full production of 1,500 tonnes of iodine per year is expected to take until late 2011.

First Quarter 2011

Agitated Leach Plant

During 2010, detailed engineering and construction of the modifications required to the crushing and grinding circuit of the Agitated Leach Plant ("ALP") were completed. In the latter part of the fourth quarter of 2010 the commissioning of the ALP commenced as scheduled. The plant is currently in commissioning and ramp up to full production, which is expected to take until late 2011, when the plant should reach a 1,500 tonne per year rate of iodine production.

Year End 2010

Agitated Leach Plant

During 2010, detailed engineering and construction of the modifications required to the crushing and grinding circuit of the Agitated Leach Plant (ALP) were completed. In the latter part of the fourth quarter of 2010 the commissioning of the ALP commenced as scheduled and within the budget of $3 million. Ramp up to full production of the ALP is expected to take 6 months. Material from the modified crushing/screening circuit is achieving target size, and the leaching circuit is performing according to design.

Third Quarter 2010

Agitated Leach Plant

Construction of modifications to the crushing and grinding circuit of the Agitated Leach Plant (ALP) advanced well during the third quarter of 2010, with the procurement at 100% complete and erection of the structure and equipment at just over 50% complete by September 30th. The project is on schedule for commissioning in the latter part of the fourth quarter and on budget at just under $3 million for the modifications. Additional capital expenditures will likely be required during the coming year as the plant ramps up to full capacity.

Second Quarter 2010

Agitated Leach Plant

Detailed engineering of the modifications required to the comminution circuit were completed during the quarter. Procurement and manufacture of the items required to carry out the modifications are underway. Construction will begin in the third quarter 2010 and is expected to be completed during the fourth quarter of 2010, when commissioning will begin. The project is on schedule and within budget (approximately $3 million). There may be additional optimization costs required once commissioning is complete to provide for ore variations. When fully operational, the agitated leach plant is expected to increase iodine production capacity to 1,500 tonnes per year.

First Quarter 2010

Agitated Leach Plant

Detailed engineering is in process for the agitated leach plant modifications and some elements are being tested for installation. Costs estimates are approximately $3.0 million to confirm and test the changes required. Proposals for additional crushing and screening equipment are under review. There may be additional purchase costs for equipment once testing is complete. The agitated leach plant is expected to be fully operational in 2011. When fully operational, the agitated leach plant is expected to increase iodine production capacity to 1,500 tonnes per year.

Year End 2009

New Management

As of December 1, 2009, Mr. Tim Miller was appointed President and Chief Executive Officer and has joined the Board of Directors of the Company. Mr. Miller was most recently Vice President Central and South America for Goldcorp Inc. where he was responsible for all of Goldcorp's activities in Central America, South America and the Caribbean. Prior to that, Mr. Miller spent many years with Glamis Gold Ltd. as Vice President and Projects Manager for their Central American operations. His background also includes construction and management of major heap leach and agitated leach operations throughout South and Central America. Mr. Miller has a BSc. Chemistry from the University of New Mexico and an MBA from Webster University.

Third Quarter 2009

Agitated Leach Plant

During the third quarter of 2009, the Company continued to work with its independent consultant on analyzing various possible solutions for the crushing/grinding circuit of the agitated leach plant. Further analysis of the ore feed characteristics resulted in proposed modifications, which management is currently studying to determine the proper course of action. When fully operational, the agitated leach plant is expected to increase iodine production capacity from 1,000 tonnes per year to 1,500 tonnes per year.

Second Quarter 2009

Agitated Leach Plant

During the first half of 2009, the Company installed modifications to the crushing/grinding system of the agitated leach plant based on recommendations provided by independent consultants. During the startup and testing of these modifications additional problems were encountered. As a result, a more in depth analysis of the ore feed characteristics and possible additional modifications to the crushing/grinding system are required to resolve the material processing problems.

When fully operational, the new agitated leach plant is designed to increase production capacity from
1,000 tonnes of iodine per year to 1,500 tonnes per year.

First Quarter 2009

Agitated Leach Plant

During the first quarter of 2009, the Company installed a modified crushing/grinding system to the agitated leach plant. It is expected that with some additional modifications, the agitated leach plant will be fully operational toward the end of the third quarter of 2009.

The agitated leach plant is designed to increase production capacity from 1,000 tonnes of iodine per year to 1,500 tonnes per year.

Year End 2008

During 2008, the Company initiated the commissioning of a new agitated leach plant designed to replace the existing heap leaching system. As of the date of this report, the agitated leach plant is not yet operational. (See below section "Agitated Leach Plant and Power Supply").

As a result of the recent unprecedented events in the global financial markets and its adverse impact on the capital and debt markets, the Company has deferred all major capital expenditures, including the development of the nitrates fertilizer plant, that are not directly related to iodine production. See below section "Nitrate Fertilizer Project". The Company has also initiated comprehensive cost-saving measures in efforts to reduce production and administrative costs and preserve cash. Despite the crisis, iodine prices remained stable during 2008.
