Gil Clausen
Analyst · today's presentation and Copper Mountain's first quarter 2022 Management's Discussion and Analysis for more information. I will now turn the call over to Gil Clausen, President and CEO of Copper Mountain
Good morning, everyone. And thanks for joining us. We're starting on Slide 3, presenting with me are Eric Dell, our Senior Vice President of Operations and Brad Bolger, our Vice President of Finance. I'll begin by discussing details on what impacted us so heavily in the first quarter. Eric will give a more detailed discussion on our operation along with an update on our concentrator expansion projects with the mine. Brad will present our financial results and then I'll wrap up with a summary of some of our upcoming milestones and then open the call to questions. Turning to Slide 4, getting through the quarter was a real challenge. Production was extremely low due to lower grades combined with low tonnage rates. The lower grade which was planned was due to almost all production coming from Phase 2. The tonnage was low due to the secondary crusher shaft damage in Q4 of last year, which forced us to run at reduced rates and deliver much coarser feed to the grinding circuit. We also had lower operating time due to major conveyor belt repairs to the SAG mill feed belt and modifications to the grinding circuit to run properly with coarser feed. But these issues are behind us now. New secondary crusher shaft delivered earlier this month was installed and operating by April 7. We're now ramping up the mill to target capacity of a steady state of 45,000 tonnes per day with Ball Mill 3, operating well as designed. In fact, we've been operating above the 45,000 tonne per day of late, and we have also ordered a spare secondary crusher shaft that will be arriving in August. We expect large throughput and production increases in the second quarter compared to the first and further we're beginning to mine ore from the north pit in Q2. And we'll start mining higher grade from Phase 4 mid-year. We expect production to be much stronger in the second half of the year. This production increase will have a positive impact on our cost per pound, cost this quarter were abnormally high because of the lower production rate and major non-recurring costs that are not planned to impact us for the balance of 2022. All in costs in Q1 were higher due to extensive maintenance backlog work. We completed on our shovels and drills, also building up spare parts inventory on shovel hydraulic hoses and systems to prepare the mine for increased production rates. In Q1, the company had to rent portable crushing equipment to produce crush waste for winter road material and for engineered crush mill for our sustaining capital projects, a task which is normally done with our secondary crushing circuit, because we have usually spare capacity there. That rental crushing plant has been demoed with the secondary crusher back to normal operation. We also increased maintenance contractor expenses during this period of heavy workload to assist with managing COVID-19 related maintenance workforce absences and also of course, to do that major conveyor belt repair experienced when we had that really severe cold weather that occurred late Q4 of last year. There were also other there non-recurring sustaining capital items as well. The costs associated with the assembly of the Trolley Assist haul trucks and payment for the installation of MineSense. MineSense sense actually has been a great addition to our fleet. It measures the actual copper ore grade in the shovel and loader bucket and has greatly improved our ore and waste selectivity in grade control. So these capital expense items will not recur this year as well. The construction of a new haul road underpass for vehicles leading to the mill and concentrator that began in Q1, this underpass will improve safety and greatly reduce haul truck cycle times and delays on our main waste haulage road by eliminating haulage interference from light and commercial vehicles that we're crossing the haul road to head to the mill. This road construction is expected to be complete mid this quarter. Also environmental water management projects were also included in our sustaining cost in Q1. Overall these are now all substantially complete with a few smaller scope projects left. All water management projects will be fully completed in Q3 of this year. To a lesser extent we did experience some inflationary pressures as well similar to everybody else in the industry. We saw diesel prices increased by about 60%. Steel prices are up 19% and other mill consumables up 10%. But with higher production levels throughout the remainder of the year and the non-recurring cost behind us, we expect unit cost to greatly improve in Q2 and even more significantly in this half of the year. However, we're increasing our all-in unit cost guidance to a range of US$2.25 to US$2 75 per pound, we are maintaining our production guidance of 80 million pounds to 90 million pounds of copper, but we're guiding at the bottom end of that range. We'll revisit our guidance each quarter as is our normal practice. Slide 5, despite an unpleasant quarter, we did have some big achievements. We exceeded our sustainability targets for last year, achieving at least an A rating on each of the TSM protocols. We also commissioned our Trolley Assist project. We have seven haul trucks that are now pantograph equipped and both ore and waste is being hauled up 1 kilometer trolley ramp. We're proud to be the first open pit mine to commission electric trolley assist in North America. Our electric-powered haul trucks will now travel up our haulage ramp at more than twice the speed of diesel trucks and at one-tenth of the energy cost and near zero GHG emissions, this is truly a huge success. Also in the quarter we completed the balance of the 2021 expiration drill program at the Copper Mountain Mine. We drilled to over 50,000 meters with about 28,000 meters at New Ingerbelle. We continue to see positive drilling results at New Ingerbelle, which extended mineralization at depth and to the west. That deposit remains open laterally and at a depth as does the Copper Mountain Main deposit and we're now working on updating the mineral reserve and mineral resource estimates with a new life of mine plant, which will include an expansion study as we've discussed in the past. All of which are progressing on schedule for mid-2022 release. Earlier in the quarter, we closed zero-cost collar option contracts for 3.3 million pounds of copper per month through the balance of the year with a floor price of US$4 per pound and an average ceiling price of US$4.91 per pound. I will now turn the call over to Eric who will provide more detail on our operating results and development projects.
