Analyst · today's presentation and Copper Mountain's first quarter 2021 Management's Discussion and Analysis for more information. I would now turn the call over to Gil Clausen, President and CEO of Copper Mountain. Please go ahead
Thanks, Rod. Starting on slide 10, as Gil and Rod have stated, the mine achieved another record quarter. We continue to advance Phase 3 of the mine plan, which provided higher grade mill feed, approximately 79% of ore supply was from Phase 3 during the quarter, with the remainder from Phase 2. The Phase 3 higher grade is the basis of the higher production, and is planned to be the main ore supply for the remainder of the year. Page number three, we will continue to provide supplemental mill feed for the remainder of the year at a slightly higher percentage than Q1 and moderate the mill feed grade a little more than Q1. 4.2 million tonnes of waste was moved from Phase #4 during the quarter accounting for 35% of waste movement. Page number four, we will provide about 10% of the mill feed in 2021 weighted towards the second-half of the year and will be the main ore supply in 2022. 2.2 million tonnes of waste was moved as part of the one km trolley ramp construction. This will provide a straight haulage ramp to the bottom of the main pit to the primary crusher for the next 15 to 20 years of the mine life. This haulage ramp modification will improve mine efficiency and operating cost outside of the trolley project which we will discuss in more detail later. Overall, the mine operation delivered a great quarter executing the long-term mine plan. Turning to slide no. 11, the mill delivered record production during the quarter, producing 25.5 million pounds of copper. This is 10% above the record production achieved in the last quarter, which continues to demonstrate the strength and flexibility in our production plan. We did slow the mill down at times during the quarter, while processing very high grade ore, focus on recovery, and balanced mill tonnage with copper concentrate filtering capacity. The team pushed the concentrate filtering production to record levels and continue to make minor adjustments in the flotation circuit to achieve the production level. Our longer-term plan as outlined in our 65,000 tonnes per day pre-feasibility study includes installing an upgrade concentrate thickener and installing an additional concentrate filter press. The concentrate thickener upgrade in planned this year and is well advanced. It will be in fruition in early Q3. We are also advancing engineering design for installation of the second concentrate filter press. This will allow the mill to run higher mill tonnage rates without loading concentrate handling area when processing higher grade ore. Turning to slide number 12, the mill expansion to 45,000 tonnes per day, which includes installation of a Third Ball Mill, continues on schedule for commissioning in Q3. As previously stated, the installation of BM3 will increase mill tonnage and achieve a finer grind to also improve overall metal recovery. During the quarter, the ball mill foundation area was excavated to bedrock, lean concrete, and the mill raft foundation has been poured. One of the mill bearing pedestals has been poured. And a second mill bearing pedestal is being prepared for pouring. Construction activities continue to progress well. It is important to note the mill was already onsite and ready for installation. Turning to slide number 13, we continue to pursue technology advancements. We believe we have an advantage with our team's ability to work with suppliers to test and advance new technologies. We continue to work closely with the BC Company MinseSense on both their ShovelSense technology and now BeltSense technology. These technologies use XRF ore grade in the shovel bucket and on conveyor belts. The picture on this slide is [indiscernible], which was the first hydraulic excavator in the world to test ShovelSense. We spent over a year field trialing ShovelSense prior to starting commercial production approximately one-year ago. Since that time, we have installed ShovelSense on two additional loading units and plan to install ShovelSense on remaining two loading units this year. We are using this technology to recover high grade ore from waste big packets and reject non-economic ore from high grade big packets. We are presently recovering approximately 4% more high grade ore for waste and rejecting approximately 1% of non-economic ore for mill feed. These numbers are expected to increase with installation of ShovelSense on all the loading units. We are now working with MineSense to install their BeltSense units to measure ore grade discharging the primary crusher and anchoring the mill. The objective is to achieve proactive mill control based on what is entering the mill rather than react to control based on actual performance. The BeltSense analysis will allow us to -- may allow us to increase mill tonnage and recovery. We look forward to advancing this trial. Turning to slide number 14, I will probably use this trial as another example of our team's ability to partner with suppliers to advance new technology. We have a group of quality suppliers and technology partners that are working together to make trolley successful. Copper Mountain will continue to partner to develop the next step evolution of haul truck GHG reductions, including battery, fuel cell, and hydrogen technology to achieve our goal of net zero emissions by 2035. Our Trolley Assist trial is announcing with ramp construction discussed earlier. This slide provides a couple of screenshots from an animation video of producing to visualize this project. The bottom picture on this slide shows the one kilometer street trolley ramp running from the bottom of the main pit to the primary crusher, which will support haulage of old low ore from the main pit over the next several years, hauled by old ore from the Ingerbelle pit. A trolley system expansion is planned from the new Ingerbelle pit to connect into this trolley section to complete ore haul from new Ingerbelle pit to the primary crusher. The picture on the right of the slide shows a haul truck connected to the trolley power line, while traveling loaded on that. Each haul trucks operating on trolley assist will replace over 400 liters per hour diesel or greater than one tonne of CO2 per hour. We are on schedule to commission this project in late 2021, and look forward to using this knowledge to expand the application of this technology to further reduce our GHG intensity. Turning to slide number 15, we continue to move forward with our GHG reduction objective. We achieved the 23% reduction in GHG intensity in 2020, compared to 2019. We reduced from 3 to 2.3 tonnes of CO2 equivalent per tonne of copper equivalent produced. We target to continue to reduce our carbon intensity in 2021 as we commissioned Ball Mill 3 and for all the assists later this year. These projects will provide full-year reduction impacts in 2022. We are also quickly advancing studying of further mine electrification, renewable diesel, and progressive reclamation offsets as the next GHG intensity reduction steps. We're making significant positive progress towards our goal of zero GHGs by 2035. I'll now turn the call back to Gil.
