<div style="font-family:Times New Roman;">
<p align="center" style="margin:0in 0in .0001pt;text-align:center;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt 1.25in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">During the year 2010, we saw a significant recovery in the prices of all of our products.&#160; We believe the fundamental drivers for these better prices have been two-fold:&#160; the stronger physical consumption of the emerging economies and the recovery of consumption but a slower pace from the developed economies.</font></p>
<p style="margin:0in 0in .0001pt 1.25in;text-indent:-1.25in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt 1.25in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">In addition to these two factors, there is the influence of financial investments that is putting some pressure on several metal prices.</font></p>
<p style="margin:0in 0in .0001pt 1.25in;text-indent:-1.25in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt 1.25in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Focusing on copper, we maintain our positive outlook for this metal in 2011.&#160; On the demand side, it is expected a worldwide demand growth in the range of four to five percent for the year that will not be matched by new copper production, estimated to grow between one and two percent.</font></p>
<p style="margin:0in 0in .0001pt 1.25in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt 1.25in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Considering current market trends, most analysts believe the market is heading towards 400,000 to 600,000 ton deficit in 2011 that should bring support for high market prices.&#160; However, even though we believe there are very strong market fundamentals for copper, we also think that the investor community is overlooking the following current developments:</font></p>
<p style="margin:0in 0in .0001pt 1.25in;text-indent:-1.25in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt 1.5in;text-indent:-.25in;"><font size="2" face="Symbol" style="font-size:10.0pt;">&#183;</font><font size="1" style="font-size:3.0pt;">&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160; </font><font size="2" style="font-size:10.0pt;">Current inventory levels do not reflect the market as tight as prices may suggest.&#160; As of February&nbsp;2nd, that&#146;s yesterday, the combined inventories of the London Metal Exchange, COMEX, and Shanghai warehouses were at 594,500 MT, about 55,700 tons higher or 10 percent more than the 538,800 MT that were at these facilities as of September&nbsp;30, 2010.</font></p>
<p style="margin:0in 0in .0001pt 1.5in;text-indent:-.25in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt 1.5in;text-indent:-.25in;"><font size="2" face="Symbol" style="font-size:10.0pt;">&#183;</font><font size="1" style="font-size:3.0pt;">&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160; </font><font size="2" style="font-size:10.0pt;">The second element is that there is strong price volatility in metal markets, particularly in copper.&#160; As an example, in December, copper prices varied over 54 cents between its peak and valley and for the last three months, the difference between peaks and valleys have averaged 37 cents, so there is a volatility as well as inventories that are growing.</font></p>
<p style="margin:0in 0in .0001pt 1.5in;text-indent:-.25in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

<p align="center" style="margin:0in 0in .0001pt;text-align:center;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt 1.25in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">We believe the market is currently anticipating a very strong copper scarcity, but this has to be verified by reality. &#160;In other words, higher physical consumption has to come from the main consumers such as China, Europe, and the U.S.&#160; We do believe that we are at an excellent moment for copper, but as I stated at the beginning of this part, but we also think that the copper market price maybe overreacting to an expectation.</font></p>
<p style="margin:0in 0in .0001pt 1.25in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt 1.25in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Considering the current market circumstances and the indicated volatility, the Company has decided to take some price protection through the use of swaps and zero-cost collars.&#160; We will come back to this point later on during the conference call.</font></p>
<p style="margin:0in 0in .0001pt 1.25in;text-indent:-1.25in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt 1.25in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Let me focus on molybdenum now.&#160; As you know, Southern Copper&#146;s main by-product is molybdenum.&#160; In the year 2010, this metal represented 13 percent of company sales and we&#146;re currently seeing a soft recovery in molybdenum consumption.&#160; For the year 2011, we&#146;re expecting a relatively balanced market for this metal.</font></p>
<p style="margin:0in 0in .0001pt 1.25in;text-indent:-1.25in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt 1.25in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Turning to our production, and starting with copper; let me first say that the company decided to change the name of the Cananea operating unit.&#160; Now, it is called Buenavista del Cobre.&#160; This change is to better reflect the startup of a new era for this asset.&#160; So from now on, we will call this operation Buenavista instead of Cananea.</font></p>
<p style="margin:0in 0in .0001pt 1.25in;text-indent:-1.25in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt 1.25in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Focusing on copper production, the company&#146;s copper mined production in the fourth quarter increased by 3.5 percent to 130,553 tons compared to 126,087 tons for the fourth quarter of 2009.&#160; This increase was mainly the result of 15,700 tons of SXEW copper production coming from our Buenavista mine.</font></p>
<p style="margin:0in 0in .0001pt 1.25in;text-indent:-1.25in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt 1.25in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The Toquepala mine production also increased to 37,446 tons as compared to 35,166 tons in the fourth quarter of 2009 due to higher ore grades and recoveries.&#160; These increases in production were partially offset by lower production at the Cuajone and Caridad operations, which reduced their production by 24 percent and six percent, respectively, due to lower ore grades.</font></p>

<p style="margin:0in 0in .0001pt 1.25in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Speaking about the repairs of the Buenavista units, as we have previously reported to the market, the Company has aggressively initiated the reconstruction and ramp-up of Buenavista.&#160; Through December&nbsp;31, 2010, we have spent $70.9 million in repairs.&#160; Of those, $35 million were capitalized and $35.9 million were charged to operating costs during 2010. For 2011, we expect to spend $43.1 million to complete the repairs of this operation.</font></p>
<p style="margin:0in 0in .0001pt 1.25in;text-indent:-1.25in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt 1.25in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">We&#146;re maintaining the estimated cost of the repairs at approximately $114 million.&#160; An undetermined portion of the total expenditures should be recovered from insurance.</font></p>
<p style="margin:0in 0in .0001pt 1.25in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt 1.25in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">As we previously disclosed to the market, the SXEW production of Buenavista reached full capacity in the 4Q10.&#160; At the beginning of this year, the company partially started the concentrator plant.&#160; Currently, Buenavista is running at 70 percent of capacity and we expect to reach full production by the end of this quarter.&#160; For 2011, we expect to increase the Company production level by 26 percent, producing 630,000 tons of copper.&#160; Of that, approximately three percent will be from third parties copper.</font></p>
<p style="margin:0in 0in .0001pt 1.25in;text-indent:-1.25in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt 1.25in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">For molybdenum production, as indicated in our press release, in 2010 we reached a new molybdenum production record of 20,519 tons, 10 percent higher than the 18,687 tons produced in 2009.&#160; The fourth quarter molybdenum production increased also by four percent to 5,246 tons compared to 5,052 tons in 4Q09.</font></p>
<p style="margin:0in 0in .0001pt 1.25in;text-indent:-1.25in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt 1.25in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">During the year 2011, we will have a reduction of molybdenum production due to a temporary reduction in our Peruvian operations ore grade.&#160; This ore grade decrease will be partially offset by higher production expected from our Mexican unit of La Caridad.&#160; Our 2011 guide for molybdenum production is 17,000 tons for the year.</font></p>
<p style="margin:0in 0in .0001pt 1.25in;text-indent:-1.25in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt 1.25in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Turning to financial results and specifically in sales, focusing on Southern Copper financial performance, the fourth quarter of 2010 sales were $1.5 billion, 32 percent higher than the 1.1 billion we had in the fourth quarter of 2009.&#160; The full-year 2010 Company sales were $5.1 billion, 38 percent higher</font></p>

<p style="margin:0in 0in .0001pt 1.25in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">As we reported to the market, the Company entered into copper hedge contracts to reduce price volatility and protect sales value.&#160; Swaps contracts are currently hedging approximately 28 percent of 2011 copper production at an average price of $4 per pound equally spread through the year.</font></p>
<p style="margin:0in 0in .0001pt 1.25in;text-indent:-1.25in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt 1.25in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The Company has also hedged approximately 31 percent of 2011 copper production using zero-cost collars with an average floor price of $3.02 per pound and an average cap price of $4.84 per pound.</font></p>

And if you allow me to ask a second question, just related to your   costs, you obviously had a very positive performance through this quarter.   You just mentioned the 23 cents per pound of cash cost including by-products.   I just wanted to get a sense of how are your views going forward? I mean, we   will probably continue to see pressures for fuel and labor. On the other   hand, Buenavista should offset this as it is lower cost. I mean, how do you   expect cash costs level over in 2011? Thanks.</font></p>    </td>   </tr>

As I mentioned, we   have reduced the outlook of production for molybdenum for next year from   about over 20,000 tons to 17,000 tons for 2011.

So as part of this, several   candidates have mentioned that they are &#151; they may consider changing the   royalty&#146;s regime that the mining companies are having now.

So the   next Peruvian president will have to weigh the positive effect of the   investments given they&#146;re charging more to mining companies. So at the end of   the day, you may see what happened with the current administration that is   finishing. They had also talks about the &#151; for instance, windfall profit   taxes for mining companies during the campaign. However, once they were in   office, they thought about it and decided to promote investments rather than   charging with more taxes mining companies. So all in all,&nbsp;I think that   whatever you heard now will be thought again later on, when the winner of the   elections is in government.</font></p>    </td>   </tr>

First on the Toquepala concentrator expansion, basically, the company is   re-visiting the project because we have to identify some options that may   help to reduce the CapEx cost per ton of additional production and an increase   on the final production that this investment may have. So, in that sense, we   are doing now a review &#151; an extensive review of the projects and see if we   can have an expansion. I mean, we are looking basically at the economics of   this and its technical possibilities.</font></p>    </td>   </tr>

And what basically led to the slowdown was   the Tia Maria project &#151; Tia Maria had not expended funds in 2010 for most of   the year. Now, we want to &#151; we want to catch up on that. And we also have a   much more clear landscape regarding our Mexican investments in Buenavista now   that the operation is back and approaching to full capacity by the end of the   quarter. So when you see these two elements, we are ready &#151; we&#146;re ready to   see a much more committing possibility for growing on Buenavista than what we   have, say, at the beginning of 2010.</font></p>    </td>   </tr>

Really, it&#146;s a change in the engineering, and then we are doing a different   location for the plant than at the beginning and that is going to improve the   production because we are going to do everything by gravity. And not only the   production, because the cost of production will be reduced too and that is   the reason that we are talking that instead of 100,000, it can be 120,000 or   125,000.

First, regarding dividends, how &#151;   can you clarify to us if the assumption that all cash you generate after   CapEx would still be distributed as dividends? And my second question is also   regarding cash cost, how the ramp-up of Cananea, now Buenavista, would impact   the average cash cost in terms of &#151; the cash cost as it is, and also   including the by-products? Thanks very much.</font></p>    </td>   </tr>

And as   I explained when we discussed the dividend &#151; the approved dividend for this   quarter, each quarter meeting, the board reviews the company cash position,   the market for copper, any future payments of loans or capital expenditures   that the company has committed and on that basis approves a dividend. What   they will do in the future, it&#146;s hard to say.</font></p>    </td>   </tr>

I think you had   previously indicated in the third quarter call that you would hedge about 58%   of the fourth quarter production. So I was curious what the realized price   for copper sales in the fourth quarter might have been, or was after taking   into account the hedges you had in place relative to the U.S. $3.92 that we   averaged on the LME?</font></p>    </td>   </tr>

Because of &#151; I mean, other than the   uncertainties that you may expect such as tires that are quite dependent on   fuel prices. But several of the companies that provided you major equipment   extend their operations between 2005 and 2007. So when we &#151; regarding the   prices of 2008, they were having a significant capacity shortages and where   (inaudible) you conduct that new capacity that they build up. So I think that   in that sense, we&#146;re not seeing at this time the capital inflation that we   saw, say, in 2005 or 2006 at this point.</font></p>    </td>   </tr>

My question relates to the decrease in tons smelted and   anode production, which I presume is at La Caridad or at least the anode is.   Is this a decrease in smelting and anode production due to the labor problems   you had at La Caridad, or was it demand-driven with respect to anode?</font></p>    </td>   </tr>

Let me mention &#151; in   general, in terms of our metallurgical facilities, we have a 14% decrease in   annual production at Ilo during the fourth quarter due to technical problems   at the smelter oxygen plant. This facility operates right now at 95% of its   capacity, and we are solving these problems through the second quarter of   2011.</font></p>    </td>   </tr>

Mexican authorities established   order and secured access roads to our complex in Mexico and activities at our   Mexican metallurgical facilities were normalized shortly after that. So there   was a one-time thing that happened in the fourth quarter in the case of the   Mexican operations and in the case of the Peruvian ones, some technical   problems that have been pretty much solved already even though we will have   to address some repairs regarding our Ilo metallurgical facilities in the   second quarter.</font></p>    </td>   </tr>
