[QUOTE="Barra_Mad, post: 103721, member: 2114"] Hey mate as said before no suck thing as a dumb question and in theory yes you can get gold from slate with no quartz. This is dependent on a few factors in case of the Bendigo black shale they contained gold that was trapped by bacteria and drawn down into the mud of a delta. this was then buried and compressed to become Shale. Its the biological matter that give the black shale there color. so once these layers of rock had been formed and faults and folding started to take place the hot salt water around 300 degrees C flowed through leaching the gold out and depositing it in the quartz veins that make up the famous Bendigo lode. This has recently been studied and found that there is almost no gold below 600m in the Bendigo zone because of this. In fact it is the salt water that gives gold bearing quartz its color because tinny bubbles are formed when the vein solidifies and these trap water so when the light hits the quartz it is reflected and has the same effect that water in a cloud, so this is how get milky quartz gets its white color unlike the quartz in granite which is clear. So in short yes but it would be rare and in very small quantities. [/QUOTE]
