Toe vili pito pito i luga samala vili

MININGWELL fa'amau fa'amau fa'amau e faia i u'amea u'amea maualuga maualuga ma tungsten carbides. E ala i le fa'afefeteina o le vevela, o a tatou mea faigaluega vili e lava le malosi e fa'afetaui ai mana'oga e viliina ma'a ma maua ai le fa'aitiitia o le malosi a'o viliina ma'a. E le gata i lea, e mafai ona tatou mamanuina fa'aigoa fa'amau fa'amau fa'amau vili e tusa ai ma fa'aoga eseese e viliina, ma fa'aaganu'u vili fa'aaoga e fa'aoga i le ma'a vaivai, papa ma'a ma'a.
