Gold Miners vs Gold Bullion

It seems to happen a few times a year, where the gold miners get beaten down in value yet the bullion itself remains fairly strong. We have seen this again in the last month. Gold is near an all time high yet, the mining stocks have been punished loosing 20% of their value. I have both miners and bullion ETFs. I was looking for opinions on the following. I fully expect the broad stock market to go down in value with another crash at some point. During that time GOLD itself I expect will continue on its rise. My question is, will the gold miners continue to reflect the movements of the general markets, or will they break trend and follow the GOLD bull market? Why? Why do the miners get beaten down during market turns? Is it due to big funds selling their shares to cover other loses, etc. Comments?

Thanks
Bill
