) (TSX: TV, BVL: TV; OTCQX: TREVF, Frankfurt: 4TI)

announced on June 26th that 19 workers at the Santander mine in Peru tested positive for COVID-19 during routine serological testing. In response, operations at Santander were suspended and all 298 workers on site were safely quarantined and underwent further testing. A total of 82 workers have tested positive for COVID-19 using polymerase chain reaction (PCR) tests. Three individuals are currently displaying mild symptoms while all other workers are presently asymptomatic. Operations remain suspended to focus on the health and safety of Santander’s workforce and the community. 

The Santander operation has health professionals in place to monitor and provide medical support to the workforce and additional resources are being brought in where required. Workers that tested negative and who are not required for critical tasks at the operation are being transported offsite to their homes. Workers who have tested positive will remain in safe quarantine for up to two weeks. If symptoms develop, the affected workers will be transported to medical facilities for treatment.

Ricus Grimbeek, President and CEO, stated, “Care for our workforce is our top priority. We have suspended the mining and milling operations at Santander and are focusing on providing a safe environment to workers so that they can continue their quarantine. I am grateful that the vast majority of workers affected are currently asymptomatic with the remaining few showing mild symptoms, and to the team for their quick action in following the plan that we put in place at the onset of the pandemic. We are working with our main contractors and government to determine new screening and testing protocols before we determine a re-start date. The health and well-being of workers will be our primary focus in any decisions made.”
