Pan American Silver (TSX: PAAS)  e phatlalalitse  hore ts'ebetso e tsoetse pele merafong ea eona ea Dolores le La Colorada Mexico, ka mor'a ho qala bocha ha Shahuindo, La Arena, San Vicente le Manantial Espejo, e qalileng ka May.

Qalong merafo e sebetsa ka matla a fokotsehileng ho amohela liprothokholo tse ncha ho arabela covid-19, Pan American e boletse.

Pan American le eona hajoale e emetse tumello ea taolo ea ho qala ts'ebetso ea Huaron le Morococha naheng ea Peru.

Moetsi oa silevera oa bobeli ho fetisisa lefatšeng o  emisitse ts'ebetso e tloaelehileng  merafong ea hae Mexico, Peru, Argentina le Bolivia ka Hlakubele ho latela mehato e tlamang ea ho behelloa ka thoko.

Meepo ea Timmins West le Bell Creek naheng ea Canada e tsoetse pele ho sebetsa ka 90%. 

"Re ntse re tsoela pele ka mokhoa o hlokolosi oa ho qala ts'ebetso hape, ha re ntse re sebeletsa ho khutlisetsa maemo a felletseng a tlhahiso ts'ebetsong ea rona ha re ntse re sireletsa bophelo bo botle le polokeho ea batho ba rona," CEO Michael Steinmann o itse.

Pan American e ile ea hula tataiso ea eona ea ts'ebetso ea 2020 ka la 12 Hlakubele 2020, ka lebaka la ho hloka botsitso ho amanang le seoa sena.

Motšehare oa Labobeli, setoko sa Pan American se ne se theohile ka 6% ho TSX. Khamphani e na le chelete ea 'maraka ea C $ 8.1 bilione.
