Alumbrera operations

During the three months ended June 30, 2007, the Company recorded equity earnings of $19,277,000, a 49% decrease from the same period in 2006. The decrease is primarily due to the planned lower copper and gold grades mined, lower copper and gold recoveries, lower realized copper prices and higher royalty expenses in Q2 2007 compared to Q2 2006. These factors are described in greater detail below.

The average copper grade mined in Q2 2007 was 0.55% compared to 0.61% in Q2 2006. Recoveries of copper were also lower compared to Q2 2006 as a result of stockpile blending and processing of high gypsum content material in 2007. Both the lower copper grades and the lower recoveries led to a 13% decrease in copper production during Q2 2007 compared to Q2 2006.

The average gold grade for Q2 2007 was 0.61 grams per tonne ("g/t") compared to 0.77 g/t in Q2 2006. This, combined with lower gold recoveries for the same reasons as lower copper recoveries, resulted in a decrease in gold production of 26% in Q2 2007 compared to Q2 2006.

Average realized copper and gold prices in Q2 2007 were 18% lower and 9% higher, respectively, than for the same period in 2006. Average realized prices can differ from average spot prices as metals sales prices are subject to adjustment on final settlement. In a rising copper price environment which was experienced in late Q1 and early Q2 2007, these provisional adjustments on certain sales recognized during the previous two quarters resulted in a realized price of $3.66 per pound of copper during Q2 2007, slightly higher than the average spot price of $3.47 per pound for the period.

Cash costs per pound of copper net of gold credits increased from $0.32 in Q2 2006 to $0.89 in Q2 2007. Part of the increase was due to an increase in royalties commencing in May 2006. In May 2006, Alumbrera started to accrue for royalties payable to Yacimientos Mineros de Agua de Dionisio ("YMAD Royalty"), a quasi-government mining company which owns and administers all mining prospects in the Farallon Negro district, the region which includes the Alumbrera Mine. Under a royalty agreement put in place prior to project construction, the YMAD Royalty is equal to 20% of net proceeds after capital recovery and certain other adjustments including changes in working capital, and is payable in the fiscal year following the one in which positive net proceeds are realized. The YMAD Royalty obligation increases if a significant distribution to the Alumbrera shareholders is made. During Q1 2007, Alumbrera made a $400 million distribution to its shareholders (of which the Company's share is $50 million). As a result, a large YMAD Royalty expense was recognized in Q1 2007. During Q2, decreases in Alumbrera's working capital, as a result of tax payments and a further shareholder distribution, also generated a significant YMAD Royalty obligation. The YMAD Royalty is in addition to a royalty which the Alumbrera Mine already pays to the Province of Catamarca.

In late March 2007, adverse weather conditions in the Santa Fe province in Argentina resulted in widespread flooding which damaged a section of the rail line used by Minera Alumbrera to transport its concentrate to the port. As a result, one shipment scheduled for late March was delayed until April, and shipments scheduled in April were delayed until May, causing Minera Alumbrera to declare "force majeure" on these deliveries. The rail line was repaired in late April allowing Minera Alumbrera to lift the "force majeure" declaration. Production at the mine site has not been affected by the floods.

Alumbrera currently has a molybdenum flotation circuit under construction which will be used to produce a separate molybdenum concentrate for sale. The circuit is expected to come on line as scheduled later in the third quarter of 2007.

Alumbrera Non-GAAP Measures

The Company believes that conventional measures prepared in accordance with Canadian GAAP do not fully illustrate the ability of Alumbrera to generate cash flow. In this MD&A, the Company has reported its share of earnings before interest, depletion, depreciation, amortization and tax ("EBITDA") at Alumbrera. This is a liquidity non-GAAP measure which the Company believes is used by certain investors to determine the Company's ability to generate cash flows for investing and other activities. The Company also reports cash costs per pound of copper (net of gold credits), another non-GAAP measure which is a common performance measure used in the base metals industry. These non-GAAP measures do not have any standardized meaning prescribed under Canadian GAAP, and therefore they may not be comparable to similar measures employed by other companies.

The following table provides a reconciliation of EBITDA and cash costs per pound (net of gold credits) to the financial statements:

Cash costs net of gold credits increased to $0.89 per pound of copper in Q2 2007 from $0.32 per pound in Q2 2006. The primary cause for the increase is the introduction of the YMAD Royalty in May 2006 as described above. In addition, costs of production have also increased in the last twelve months due to rising costs of fuel, electricity, tires and reagents, and higher rates for price participation, treatment and refining charges, and ocean freight. In Q2 2006, gold credits contributed to a lower cash cost as gold sales were high for that quarter.

Agua Rica

In October 2006, the Company received a Feasibility Study Update ("FSU") on its 100% owned Agua Rica copper-gold-molybdenum project. The FSU, which assumed the development of the Agua Rica deposit on an independent basis, indicated that Agua Rica was technically feasible and economically viable and could be developed as a long life copper-gold-molybdenum mine with a low cost of copper production and significant by-product credits. Key results of the FSU, which was prepared by Hatch Ltd. and Amec, are available on

In June 2007, Minera Agua Rica, the Company's wholly-owned subsidiary, submitted the Environmental and Social Impacts Assessment Report on its Agua Rica project to the Province of Catamarca, Argentina. The ESIA, which outlines the economic and employment benefits to the local communities in accordance with updated international guidelines, is the final submission required to receive the operating permit for mine development. The process to receive the development permit is estimated to take 8 to 12 months.

During Q2 2007, the Company incurred cash expenditures of $4,432,000 on advancing the Agua Rica project, which included the completion of the ESIA as well as basic engineering studies. For the six months ended June 30, 2007, these cash expenditures totalled $9,972,000.


Corporate expenses in the three and six months ended June 30, 2007 were generally in line with the same period in 2006 except for the following items:

A foreign exchange gain of $6,002,000 was recorded in Q2 2007 as a result of the Company holding approximately 37% of its cash balances in Canadian dollars at June 30, 2007 while the Canadian dollar strengthened during the quarter. The U.S. dollar to Canadian dollar exchange rate stood at 1.1546 at March 31, 2007 and dropped to 1.0654 at June 30, 2007. The foreign exchange gain is net of foreign exchange losses of $1,097,000 resulting from holding Canadian dollar liabilities. A smaller foreign exchange gain was recorded in Q1 2007. No significant foreign exchange gains or losses were incurred in the first two quarters of 2006.

Property maintenance and exploration of $653,000 in Q2 2007 (Q2 2006 - $421,000) included expenditures of $542,000 (Q2 2006 - $375,000) for general exploration on the Company's properties in the provinces of Mendoza and Neuquen in Argentina. Prior to the first quarter of 2006, exploration costs were not significant. The Company commenced a regional exploration program in these areas during the third quarter of 2006.

In Q2 2007, the Company incurred transaction costs of $325,000 in connection with the business combination arrangement with Yamana Gold Inc. announced on July 19, 2007. These costs, which include legal, accounting, and shareholder meeting costs, are expected to increase in Q3 2007.

Interest and other income increased from $2,224,000 in Q2 2006 to $2,788,000 in Q2 2007, due to the Company's average cash balances increasing by approximately 35% compared to Q2 2006, and due to interest rates rising by about 40 basis points over the past 12 months. In Q2 2006, interest and other income included a gain on sale of marketable securities of $401,000. At June 30, 2007, $850,000 in interest receivable was included in other receivables on the balance sheet.

Liquidity, Capital Resources and Outlook

At June 30, 2007, the Company had working capital of $237,232,000 (December 31, 2006 - $176,761,000) and cash and cash equivalents of $237,207,000 (December 31, 2006 - $178,956,000). Cash balances were up in 2007 mainly due to total cash distributions of $55,000,000 received from the Alumbrera mine in the first half of 2007, cash of $4,055,000 received from the exercise of warrants in March 2007, and interest income generated by these cash balances. The Company had no long-term debt at June 30, 2007, other than asset retirement obligations and royalty and net proceeds interest payable.

Copper prices have rebounded strongly and gold prices have increased since December 31, 2006. The Company anticipates that copper and gold prices will remain strong through the remainder of 2007. For the second half of 2007, the mine plan at Alumbrera calls for the mining of zones that are of overall slightly higher copper grades (average - 0.57%) as that achieved in during the first half of 2007 (average - 0.52%), and higher gold grades (average - 0.73 g/t) as compared to the first half of 2007 (average - 0.57 g/t). Recovery rates for the remainder of 2007 for copper and gold are expected to be slightly higher than those achieved in the first half of 2007. The following graphs show the actual and estimated grades and recoveries for copper and gold for each of the quarters in 2007:

To view the graphs please click on:

Based on current commodity prices, market conditions and planned production levels at Alumbrera, the Company expects to receive significant cash flows from Alumbrera for at least the next eight to nine years, which, along with the Company's current cash balances, could provide a significant part of the equity necessary for the Company to bring Agua Rica into production. The Company will also require significant external financing or third party participation in order to bring Agua Rica into production. However, if volatile global and market conditions result in a significant decline in commodity prices, then the cash flows from Alumbrera may become insufficient to advance any of the Company's projects, including Agua Rica, to the production stage, and to fund other acquisition projects.

If so, over the long-term, the Company will be required to obtain additional funding either through the public or private sale of equity or debt securities of the Company, or through the offering of joint venture or other third party participation in Agua Rica in order to bring Agua Rica into production. There can be no assurance that any additional funding will be available to the Company or, if available, that it will be on acceptable terms. If adequate funds are not available, the Company may be required to delay or reduce the scope of its activities to bring Agua Rica into full production.

Regardless of the completion of the Company's business combination arrangement with Yamana Gold Inc., the Company will continue to build upon its progress to date with a strategy to advance Agua Rica so as to achieve maximum monetary returns in the shortest time frame.
