It has recently been demonstrated that under identical conditions, GBM yields more gold than the traditional amalgamation method. Despite this advantage, GBM is not widely used outside Benguet.

I have been hearing from a few people that they use straight borax for flux. I ran out of my flux mid project and decided to give it a try and it worked pretty good. I have used several different fluxes before, from handy flux, superior flux, dandix, firescoff, but I really don’t have enough experience or side by side comparison experience to say that I really loved one over the other.
