During the second half of 2020, exploration activities at the Bonsucesso project were resumed as planned and engineering studies are expected to resume in the first quarter of 2021. Bonsucesso is expected to extend the life of mine of Morro Agudo and use the existing mine facilities of the complex. Magistral engineering studies continue to progress and we expect to advance further detailed engineering and optimization opportunities to mitigate the risk of project execution in 2021. In the fourth quarter, we also restarted exploration activities at the Hilarión project. In addition, the pre-feasibility studies at Shalipayco and Pukaqaqa remain on hold, and Florida Canyon was also placed on hold.
During the pandemic, Nexa allocated approximately US$ 15 million, including donations and operating expenses, to support the municipalities and regions where it is present in Brazil and Peru in the fight against Covid-19. We donated more than 780,000 items to the public health service, including rapid tests, PPE and supplies for the municipalities, in addition to oxygen cylinders, and dozens of hospital equipment for advanced life support, such as respirators, x-rays, among others.
Although provided for in Brazilian law, we decided not to reduce working hours and the fixed remuneration of employees. We maintained jobs and hired 738 people throughout the year, ending the period with 5,349 employees. Our annual climate survey showed that, despite the impacts of the pandemic, our people remain motivated and proud to belong to an increasingly plural and innovative organization.
For socially vulnerable communities, also with the support of Instituto Votorantim, we donated approximately 20,000 food baskets, which benefited more than 14,000 families in Brazil and Peru. Moreover, we provided technical support to municipal health agencies in establishing health protocols, digital health management solutions and telemedicine. The initiatives brought us closer to the communities and further demonstrated our responsibility as co-creators of a legacy in the regions where we operate.
An important commitment we made during the year was with the Women in Mining movement, which seeks to foster gender equality, expanding opportunities for women to participate in mining activities. This initiative represents another step in our goal to build the mining of the future. This means mining that values differences, respects diverse opinions and fosters this plural environment, which encourages inclusion and diversity.
In this year full of challenges and learning, we were sure that Nexa is following the right path, in line with our strategy of growing with responsibility and sustainability, maintaining the excellence of our operations, and helping to build a positive legacy for the communities around our operations. Finally, I would like to thank the Board of Directors for their trust and the dedication of our employees, who are fundamental to overcome this challenging moment.
