Hey, Phx area here.
Actually the two methods are underground and liquid injection/extraction.
The second is obviously much cheaper even though the depth here is said to be comparatively shallow (hard to believe at kilometer plus). The in situ extraction has issues you are likely familiar with due to our newer copper mines in AZ.
