Prospecting & Detecting
Placer Channel Sampling
July 2013 by Jim Halloran
Sampling gold placers can be rewarding, but remember to treat the samples so you are not high grading or low grading your results. Learn the rules and apply them so your samples are accurate.

Some creeks have nuggets, while others, particulary the rivers, nothing but fine gold.

Refractory Gold Processing
After your excitement peaks when you first receive the high gold assay from the vein you just exposed, you ponder how you will extract and sell your gold. You will need to develop a flow sheet for your process to optimize your recovery and minimize your costs and permit requirements.

I love to dry wash old nugget patches found by detector operators, and I have found my fair share of gold dry washing those areas. I have also found a few nuggets using a detector on the bedrock exposed by dry washing the patches.
Drywashing in Black Canyon, Arizona

It had been well hidden.
