Ayyuka sun fara haɓaka a ma'adinin zinare na Penasquito na Newmont da ma'adinin gwal na Alamos Gold's Mulatos.
A ranar Litinin, Excellon Resources (TSX: EXN) ta ba da sanarwar sake fara ayyukanta a cikin ƙasar, ciki har da Platosa, ma'adinin azurfa mafi girma na Mexico.
Avino Silver & Gold (TSX: ASM, NYSE:ASM) ya kuma bayar da rahoton a ranar Litinin yana fara aiwatar da ayyukan aiki a ma'adinan ta Avino kusa da Durango, Mexico.
Kamfanin bincike da haɓaka Bacanora Lithium (LON:BCN) sanarwar da cewa yana sa ran sake buɗe masana'antar matukin jirgi na Hermosillo a aikin sa na lithium na Sonora a wannan watan.
Endeavor Silver (TSX: EDR) (NYSE: EXK) ya kuma koma aiki a ma'adinan zinare uku na karkashin kasa a Mexico. A halin yanzu, Fortuna Silver Mines (NYSE: FSM) (TSX: FVI) ya koma aiki a ma'adinan San José , a kudancin jihar Oaxaca na Mexico.
Mexico ce ke da alhakin kusan kashi 23% na samar da azurfa a duniya, tana fitar da fiye da oza miliyan 200 a bara, sama da oza miliyan 196.6 a cikin 2018.
Har ila yau kasar tana da manyan ma'adinan tagulla da zinc, wanda Grupo Mexico da Kudancin Copper ke sarrafawa, kuma suna samar da adadi mai yawa na zinare, wanda ke sa bangaren hakar ma'adinan ya dauki nauyin kusan kashi 4% na yawan amfanin gida na kasar.
"Hukumomin tsafta sun sha kiran bangaren ma'adinai mafi kyawun kayan aiki kuma mafi kyawun shiri don komawa aiki," in ji Quiroga a cikin hirar S&P Global Market Intelligence Intelligence .
Quiroga ya ce Ma'aikatar Kwadago ta Mexico za ta gudanar da binciken takamaiman kiwon lafiya na coronavirus daga jami'an da za su iya ziyartar wuraren ma'adinai ba tare da sanar da isowarsu da farko ba.
"Ba za su sami mai da hankali kan hukunci ba," in ji Quiroga. "Idan akwai wani abu ba daidai ba, za mu gayyaci kamfanoni don gyara shi."
