Macdanta Otter Juan nikkel waa mid ka mid ah miinooyinka ugu da'da weyn gobolka Kambalda ee Galbeedka Australia, oo qiyaastii 630 kiiloomitir bari ka xigta magaalada Perth. Ka dib markii si ku meel gaar ah loo xidhay oo si guul leh loo iibiyay, miinada Otter Juan ee faa'iidada aadka u leh waxaa ka shaqaynaysay Maamulka Miino ee Goldfields muddo sanado ah. Iyada oo hawlgallada ay ka badan yihiin 1,250 m ka hooseeya oogada, waa mid ka mid ah miinooyinka ugu qoto dheer Galbeedka Australia.
Xaaladaha guud ee miinada ayaa keena soo saarista macdanta pentlandite, taas oo ah iskudarka nikkel sulfide oo ka kooban ilaa 4% nikkel, oo aad u adag. Miinadu waxay leedahay bay'ad walaac sare leh iyo talc chlorite ultramafic ultramafic oo ka laadlaadda cufka darbiga. Macdanta miinada waxaa loo qaadaa Kambada Nickel Concentrator si loogu habeeyo.
Xaaladaha carrada ee dhibka leh ee ka jira miinada Otter Juan waxaa aad uga sii adkeeyey dhaqdhaqaaqyada seismic ee kordhay. Sidaa darteed, Maareynta Miinada Goldfields waxay dooratay inay isticmaasho OMEGA-BOLT dabacsan oo leh awood rarkeedu dhan yahay 24 tan si loo dejiyo meelaha laga soo saaro. Sababo la xiriira hantideeda jireed, OMEGA-BOLT waxaa loo qoondeeyay in loogu isticmaalo gobollada macdanta seismically firfircoon, maadaama ay bixiso heer sare oo qallafsanaan si loo habeeyo dhaqdhaqaaqa dhulka.
