Thank you, Brad.
We are now on Slide 17. Capstone continued the development of our company-wide ESG strategy. In Q4, our senior leadership team outlined Capstone's sustainability vision, which includes reducing our carbon footprint, focusing on water stewardship and tailings management, investing in our workforce, and integrating sustainability throughout our value chain.
In 2022, we will undertake a company-wide initiative to develop our strategy to reduce greenhouse gas emissions and build target setting processes. We are also committed to enhancing our ESG disclosures. This year, we will start incorporating the TCFD recommendations into our annual sustainability report in addition to the GRI and SASB reporting standards.
On the environmental front, at Cozamin, construction began in November for the new tailings filtration and paste plant, which is needed for conversion to a dry stack tailings storage facility and underground paste backfill system. This project will reduce our tailings footprint, support tailings safety and reduce water consumption. We look forward to providing updates as this project advances throughout 2022.
Pinto Valley completed the purchase of new dust collector units and began the installation process in Q4. The new and more efficient units will reduce dust emissions and do not require the use of water. We are also improving our health and safety system. We are proud to share that we've implemented our 9 pillar safety management system at our operations. In Q4, we conducted internal audits to the management system at Pinto Valley and Cozamin with peer participation from all sites.
We continue investing in the development of our workforce. In Q4, we are highlighting the achievements of our sites in employee training and development. Cozamin is an accredited training and certification center by Mexico's National Industry Competency Standards Organization. In 2021, Cozamin achieved its goal of certifying or recertifying 100% of employees and on-site contractors in their job functions, most of whom were mine operators.
At Pinto Valley, 178 employees participated in its Leadership Academy training program in 2021 and 100% of line leaders achieved their Inspiring Leader Certificate. Pinto Valley's continued focus on training, development and succession planning in 2021 resulted in a record number of promotions and personnel development opportunities, many at the supervisor and superintendent levels.
We're now moving to Slide 18. We recently mailed out the materials for the special meeting of shareholders to approve the Mantos transaction, which will be held virtually on February 28 at 10 a.m. Pacific Time. The materials, including the proxy, management information circular, form of proxy and instructions to register and attend the meeting, were filed on SEDAR and are also available on our website.
Yesterday, we announced that both ISS and Glass Lewis have recommended that shareholders vote FOR the proposed business combination with Mantos. In support of their recommendation to shareholders, both independent proxy advisory firms reiterated the strategic merits of the transaction, which will create a premier copper producer with transformational near-term growth and meaningful synergies.
The proxy voting cutoff is February 24 at 10 a.m. Pacific Time. We encourage our shareholders to vote in advance of the meeting and remind them that there are several methods to vote, as indicated in the meeting materials. If you need assistance voting your shares, you can contact our proxy solicitation agent, Laurel Hill Advisory Group. Since the transaction's announcement, Capstone Copper's integration planning has been in the works and is advancing well.
I'll leave you now with Cashel Meagher.
