If I remember correctly, the Screws are after the mill and before the geotextile tubes. They are used to remove excess sand so that it doesn't clog up the tubes.

My understanding is that the screws are post processing not pre. They are sand screws not rock screws.

("PCFG") announced that Nevada Rae Gold, Inc., ("NRG") a subsidiary of PCFG, has purchased a 36" twin sand screw for use at the Black Rock Canyon Mine. The sand screw works with the plants' hydro cyclone to remove larger particles of sand prior to the process slurry being fed to the geotextile tubes. The removal of this larger sand reduces the volume of material being fed to the geotextile tubes and helps to manage the clean-up of tailings from the hydro cyclone.
