Kaban-chan... If there's no Sandstar there either... What's going to happen to us...?Let's go to Tsuchinoko-san's place tomorrow.Right...Sandstar used to come out of the mountain in the past, right? So if we went there...Though I don't know how much she's got left either...Here, Serval-chan - today's Sandstar.Thanks, Kaban-chan!With this, our reserves have run out...Serval-chan, that was hundreds of years ago...There's only an abandoned mine there now.
Is "abandoned mine" a good translation for 採掘跡?
