How rich does a hard rock ore have to be for it to be worthwhile to process and extract the gold?

The nugget sat there in plain sight, though it was covered in dirt, while hundreds of people had passed that way every day.

I decided to dig near it to see if there were any more and immediately uncovered others. In total I found a pocket with over 100 crystals in it. I was hooked.

There weren’t as many pieces of gold, but what I did find was bigger. As I worked my way down towards the spot that I had been working the first three days, I noticed a large crack that crossed the river.

From this I inferred that engine 2 had a carburetor problem. In this article, I discuss the specific engine/carburetor problem, and the surprising solution to this problem.

Fortunately, there are products on the market that can address these problems and make a small-scale mining operation feasible.
