Pan American ya dawo da ayyukan Mexico
Pan American Silver (TSX: PAAS) ya ba da sanarwar cewa an dawo da ayyuka a ma'adinan Dolores da La Colorada a Mexico, biyo bayan sake fara ayyukanta na Shahuindo, La Arena, San Vicente da Manantial Espejo, wanda aka fara a watan Mayu.
Ma'adinan suna aiki da farko da ƙarancin ƙarfi don ɗaukar sabbin ka'idoji don mayar da martani ga Covid-19, in ji Pan American.
Har ila yau, a halin yanzu Pan American yana jiran izini na doka don ci gaba da ayyukan Huaron da Moroko a Peru.
Mai samar da azurfa na biyu mafi girma a duniya ya dakatar da ayyukan yau da kullun a ma'adinan ta a Mexico, Peru, Argentina da Bolivia a cikin Maris don bin matakan keɓewar ƙasa.
Ma'adinan Timmins West da Bell Creek a Kanada sun ci gaba da aiki akan iya aiki 90%.
"Muna ci gaba da taka tsantsan don sake fara ayyukan, yayin da muke aiki don dawo da cikakkun matakan samarwa a ayyukanmu yayin da muke kare lafiya da amincin mutanenmu," in ji Shugaba Michael Steinmann.
Pan American ya janye jagororin aikinsa na 2020 a ranar 12 ga Maris, 2020, saboda rashin tabbas da ke da alaƙa da cutar.
Tsakar rana ta Talata, hannun jarin Pan American ya ragu da kashi 6% akan TSX. Kamfanin yana da babban kasuwancin C $ 8.1 biliyan.
