Care and Lubrication of a Model 13 Laboratory Wilfley Table

We were met with a plethora of mechanical problems with the dry washer and even a few with the excavator that were at times frustrating, but we were in this for the long haul, so we needed to solve these problems and move forward.
His findings were not exaggerated—after running 82 buckets of gravels in two days we had a remarkable 27.8 grams of gold!
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.
Present conflicts and realizations having to do with dependence on China have illuminated the fact that suction dredge miners have a vital role to play and are an ignored and untapped domestic resource—until now.
Gold and jade are actually only minor mineral resources for the Northwestern Alaska region as a whole. Modern prospecting has focused more on base metal than precious metal resources.
The fact that mineral deposits can contribute specific types of heavy minerals is why the analysis of the heavy mineral concentrates in the streams of an area can be an important prospecting technique for finding undiscovered mineral deposits.
In part one of this two-part series on gold in Guyana, I describe artisanal mining efforts currently winning alluvial gold from small-scale placer operations located along the lower Puruni River and its tributaries.
