I have seen many samples taken originally with an eye toward getting the highest grades possible, but later someone claims that those results represent an average grade of the whole gravel deposit.

I opted for the underwater portion of the river. All I have to do is float down the river and pick large flakes and small nuggets out of cracks and crevices while staying cool in the summer heat.

I cleared the connector by poking a small Phillips screwdriver through it. To ensure the bore was clean, I dunked the connector into some water and then blew it clean with my shop air compressor.

…early last fall, I found my first gold-rich patch along a few crevices in the same river and found five grams of gold nuggets in one outing.

It’s not easy to figure out what is best without testing, and so a certain level of confusion has developed about how small the ore ought to be crushed.

There are both hard rock and beach sand types of titanium deposits, but the hard rock deposits need to be at least 10 percent titanium while the beach sands often are economic with only two or three percent titanium.
