If it is with the pyrite you can do a pretty good job with good classification and a concentrating table, a totally enclosed cyanide plant will work very well, I have even done that in California. If the gold is in the pyrite I have been having good luck with very fine grinding in an attritior, with sodium thiosulfate, 95% recovery in 1 hour.

Oxidative roasting is used extensively to pretreat base and precious metal–bearing materials and to oxidize iron sulfides to generate sulfur dioxide for fixation with lime or sulfuric acid production. For the recovery of gold from refractory ores and concentrates, roasting has been used extensively for decades.
Gold Ore Roasting Techniques Mineral Processing Metallurgy. Those types of gold ores which most frequently require roasting include ores carrying arsenopyrite, stibnite, sulphotellurides, and pyrrhotite. Straight pyritic ores, where the pyrite is present in small quantities, usually yield their gold to fine grinding and cyanidation alone.
