Analyst · today's presentation and Copper Mountain's fourth quarter 2019 management discussion and analysis for more information. I will now turn the call over to Gil Clausen, President and CEO of Copper Mountain Mining
Thanks, Gil. Both the mine and mill continued to perform well during the quarter with the grade increasing as planned. Starting on slide 6, this slide highlights the areas mined during the quarter. The main ore supply came from the highlighted area on the west side of the main pit while smaller amounts of ore came from the highlighted areas on the north and south sides of main pit. Our strip ratio dropped to 2.7 during the quarter down from 4.1 in Q3 as we exposed more ore. We continued our focus on lease development in the south side of the main pit. We remain on plan to expose higher-grade ore for 2020 and 2021 production, as per our guidance. The grade is scheduled to increase throughout 2020 as we access more high-grade ore, resulting in production more weighted towards the second half of the year. Tonnes noted on the slide are exited tonnes. However, I would like to highlight, that the mine continued at a high tonnage rate, moving 18.1 million tonnes during the quarter and 69.7 million tonnes for the year. These numbers include 3.5 million tonnes of waste, placed within the pit during the quarter. And a total of 7.6 million tonnes of waste placed within the pit during the year. These in-pit placements provided working access to advanced high-grade ore, reduced haulage cost and increased overall productivity. These in-pit placed tonnes -- in-pit waste tonnes are scheduled to be relocated to the final location within the pit, during 2020 and 2021. Turning to slide 7, during the quarter we commissioned three new haul trucks and we plan to commission four new haul trucks in 2020. These trucks will replace the older trucks in our fleet. But we're excited that these trucks are being purchased as trolley capable and are part of a plan to trial trolley assist. With trolley assist, the haul truck connects electricity supply, like a street car and replaces diesel consumption with electricity. This is targeted to reduce our greenhouse gas emissions and reduce our operating costs, as we replace diesel with electricity. And increase mine productivity, as haul trucks travel faster with trolley assist. We are partnered with Komatsu, SMS and the B.C. government to advance this trial. We are presently designing the trial, including redesigning haul ramps to support maximizing use of trolley assist. We will complete this trial in the Copper Mountain main pit, on an approximately 1 kilometer long, haul ramp. In anticipation of the trial being successful, we are completing new designs to be able to utilize trolley assist in the future, this schematics of the New Ingerbelle waste dump, incorporates a trolley assist design. We have also incorporated trolley assist in the ore haul design from New Ingerbelle, to the primary crusher. We are very excited by this opportunity and how it fits into our ESG objectives. Turning to slide 8, the mill continues to operate consistently during the quarter, achieving high tonnage rates and high operating time. The new SAG mill stream, and ball mill transformers, installed in Q3, continued to perform well, and as expected. Following the ball mill transformer installations in Q3, the ball mill speeds were increased in late Q4, achieving the higher mill tonnage rate, as targeted. The one item for discussion in the quarter is the slightly lower recovery. Turning to slide, in Q4, and during the early part of 2020, we are mining a small area of the reserve that has the finest mineralogy, and lower associated recovery. This schematic shows the three pits, main, north and New Ingerbelle. The majority of the reserve is coarse and medium-grain mineralogy, while a very small part of our reserve in the middle of the main pit is of finer mineralogy. We are mining in this area in Q4. And that is the reason for the lower recovery. The recovery was in line with expectations. Turning to slide 10, we are advancing several projects in 2020, to continue to improve the operation. As of the start of this year, we have expanded the copper concentrate filtering capacity, to handle the higher scheduled copper production in 2020 and 2021. We are now focused on installation of the direct flotation reactors, as a second flotation cleaner, by mid-2020. This project will provide capacity and stability to the cleaner circuit, supporting a higher copper concentrate grade. This was a low-CapEx, high-value project that we are expediting. The schematics on the top right of this slide shows, where the DFRs will be installed within the plant. We are continuing to move forward with the ball mill three expansion project the ball mill is now on site, as shown in this picture. We are targeting commissioning in late 2020, funded through operating cash flow. As we previously noted, we have had tremendous exploration success, with more than doubling our reserve over the last two years. We plan to continue our exploration program in 2020, focused on mineralization extensions around the, Copper Mountain north and Copper Mountain main pits. We'll be starting our exploration program, in late Q1. Turning to slide 11, we are very committed to ESG and the Mining Association of Canada, Towards Sustainable Mining or TSM standard. We will be confirming our AA tailings management rating in early 2020 and are targeting to achieve AA or A ratings on all TSM protocols over 2020 and 2021. Our progressive reclamation work as previously highlighted and shown in this slide is based on an innovative agreement with the city of Metro Vancouver Aero Transportation and our local First Nation partners. Our objective is to advance progressive recognition. We are designing for it and executing on our plan. Our focus on reducing greenhouse gas emissions, including the trolley assist trial discussed earlier is another progressive partnership. Our objective is to advance this technology and reduce our GHG emissions. We will continue to update you on our ESG activities. Summarizing our Q4 operational results, the grade has increased as planned, and we are transitioning into higher-grade ore in 2020 and 2021. The new SAG screen and ball mill oil-field transformers installed in Q3 are performing as planned. We have increased the ball mill speeds and are operating at the targeted higher mill tonnage rate. We are now focused on successfully executing the DFR and ball mill three installations in 2020. We are continuing exploration focused on adding reserves and better defining our longer-term planning. We are working towards AA or A ratings on all TSM protocols in 2020 and 2021. I'll now turn the call over to Rod to go over our financial results.
