Thank you, Brian. Good morning, everyone. Thank you for joining us today to discuss our fourth quarter and year-end results and to provide you with an update on Gibraltar and the various activities that have been on the goal for the last quarter. Gross profit for the year was roughly $52 million from our sale of 66 million pounds of copper and 1 million pounds of molybdenum on our 75% ownership of Gibraltar's 90 million pounds of copper and 1.3 million pounds of molybdenum. Peter will speak more to the financials in his presentation. In reviewing 2012, concentrate production was affected as a result of lost production in Q1 related to water issues in our granite pit. Water affected ore release and ore fragmentation, which, in turn, hindered throughput through our SAG mill. Resolving the water incursion and getting new operational plan back on track and the operating issues resolved took us well into the second quarter. In the second half of the year, throughput increased. However, we were affected by lower mill availability and subsequent operating time as a consequence of our GDP3 tie in. These events are behind us now as operations are stable. We've gotten our GDP concentrator producing the hourly rates we expect, and now it's a question of methodically increasing our recovery rates and obtaining the mill availability targets as we're not hindered by GDP3 tie-ins, a much simpler task now than what was presented to us in early 2012. There's always commentary around concentrator efficiencies and design criteria in terms of throughput. And you see many new mining operations after running for a while moving to add secondary crushing systems between their primary crushers and the SAG mills to increase throughput after they have had trouble hitting projected milling rates. To be clear in this matter, when this type of situation occurs, it indicates that the front-end engineering design and flow sheets design were flawed. Not enough work was undertaken on the feasibility study, metallurgy and grinding. Effectively what you are doing when you're adding a secondary crusher behind a primary crusher to feed a SAG mill is you're turning your SAG mill into a big ball mill. The costs rise from about $0.15 to $0.20 per ton milled for the primary crusher and secondary crusher system to $1.20 per ton milled. Secondary crushers were what was used in the 1970s before the introduction of SAG mills. They're inefficient and costly, and that's why we replaced ours a number of years ago. This issue has been raised with myself on a number of occasions, and in our instance, we do not need a secondary crusher. We did the proper engineering and analysis before we built our SAG, and we have plenty of horsepower in our GDP SAG mill and more than enough in our GDP3 concentrator to obtain throughput rates. Like I said before, those who need secondary crushers do not have that horsepower in the correct location, and it's a reflection of the original design criteria and mistaken design that were in the feasibility study. Looking at our first page, first slide on Slide 4 regarding some important statistics for the company. We mined 66.2 million tons in 2012 versus 57.5 million tons. And tons declined by 1.1 million tons through the concentrator over 2011. However, recoveries, as you can see, dropped from 88% to 85% as we moved to higher hourly throughput rates. Target hourly rate of 2,450 tons per hour is being achieved. However, we are now balancing throughput with recoveries to produce the most metal possible at the optimum throughput as we work on increasing recoveries to design levels. As I have spoken about in the last conference call, we do have work to do on increasing our recoveries but that will be resolved in the near future. Slide 5, production recovery versus throughput gives you some indication of that over the last year. This slide thoroughly illustrates that relationship. We know we can achieve 89% recovery, and we are presently in the 84% to 85% range. Right now as we increase throughput rates, our biggest challenge is ensuring we can achieve 89%. So you can see the difference from March of 2012 through December of 2012 when we were roughly at 89% and now we dropped down to 85%. We've identified 3 main issues that are affecting that, and these are distinct from the various ore domain issues evident in the ore body that I've spoken about in past conference calls that also affect recovery. First, the ball mill distribution systems adjust the distribution to even out the max flow of particle size feed to each ball mill needs to be tweaked, and we've been working on that for the past several weeks. Secondly, the ball mill trommel screens need modification to allow better split in particle size and we're changing those out one by one. Thirdly, we need to increase rougher concentrate pumping to aid in deaeration, and we expect those -- these changes to be complete by the end of the quarter. These initiatives, which are presently in the works, will be completed in the next months -- next few months, and we expect an increase in our recovery to follow. We now believe we have a clear handle on hourly throughput rate and what affects those. We're nearing the point where we see stability of our cost structure in our GDP mill as we concentrate on optimizing the circuits and focusing on business improvement and cost containment. Let me explain a little further. On the cost side, Slide 6 illustrates what we feel are onetime costs associated with our present operation as we've set up for running the GDP3 mill. On the labor front, between the mine and the mill, $0.22 per pound can be attributed to increased manpower that we've talked about in the past, tied to GDP3, with no increase in metal production. As you can all appreciate from this slide, all things being equal, unit labor cost per pound of copper produced will decrease as we had additional metal once GDP3 begins producing. With respect to maintenance costs, we have experienced -- we have expensed costs that are made up of items like undercarriage on the shovels that last 30,000 hours, front-wheel motors, to name but a few, all of which have occurred this year as a timing issue and keyed for their conservative nature with respect to capital allocations whether we expense it or capitalize it. We have taken most of our costs to expense. All of these expenses, particularly the maintenance side, have added -- and the labor side have added nearly $0.30 a pound to our copper produced in 2012. Moving forward, we have reduced our powder factor after completing the mine-to-mill analysis and what was affecting mill throughput. And while we blanketed an increase in powder factor across all ore types and waste zones in 2012, we now know or understand better where to focus increased powder factors to affect fragmentation. So we expect this cost to reduce dramatically in 2013 and going forward. As you can see, explosive costs were $0.07 per pound incremental cost per pound of copper produced. With respect to diesel consumption, we now have a new dump in operation that's been permitted, which is going to significantly shorten our waste hauls and correspondingly drop our cost per pound for diesel use. Diesel and powder costs added approximately $0.14 a pound. So we know where we need to go with our costs, and we expect to get there sometime this year. So once we begin making concentrate from the new plant, we will see all these costs rebalance in terms of cost per pound of production. John and I will be happy to answer specific questions on these matters once we get to the Q&A, if you have such. Now looking at Prosperity. We have nearly completed our answers to the information request from the federal panel. We will be submitting those by the end of the week -- end of next week, and then the next date will be public hearings, which we are waiting anxiously to begin that process. With respect to our Aley project, we have made significant progress on getting the metallurgy figured out. We produced concentrate. Next we'll be producing salable ferroniobium metal in the refractory furnace. Our recovery is lower than we think it should be, so we're continuing to investigate that. And as soon as we solve that, we will complete the flow sheet and finalize our feasibility study, which we expect sometime in the second quarter. I would like to -- oh, okay, we've got some pictures here for you as well. Looking at Slide 7, you can see our new SAG mill. The trommel screens, we actually put material to it earlier this week, and so we're now expecting to start producing concentrate. Next picture is our 20-foot ball mill. As you can appreciate, this is quite a different system than the one we presently have, where we have 6 ball mills. That was a carryover from the old Gibraltar facility. So now we have one 34-foot SAG mill and one 20-foot ball mill. So circuit control is going to be much improved, and we're looking forward to -- certainly the crews are looking forward to firing this baby up and getting to work on it. Flotation system, as you can see in the next slide, is compact and a very clean, bright-looking facility, and we're pretty happy with what's transpired with our work to this date. And it's a credit to our construction and operations crew that we've got this facility up and operating effectively on time and on budget. I would like to now turn the call over to Peter so he can comment on the financials. Peter?
