Re: Katoro sampling - probably same assay techniques of drying, crushing and Fire Assay for gold and silver. Other metals probably ICP-MS or ICP-AAS / ES for analysis. So basically the same as for rock sampling and assaying of rock samples and core / chips.
The only difference will be that the samples may not be solid so any drilling may have to change to reflect that but techniques may include pitting, trencing, window sampling, augering with a shell auger, diamond drilling with triple tubes (to retain the samples) or even now (and possibly better still) sonic drilling. All depends on the anture of the tailings, if they are in a tailings pond, or pile and what they were mined from in the first place.
Hope that helps?!
