Lake Placers #4

I knew there were signals in the bedrock, and they sounded sweet, so I headed off to gather tools. We had a small sledge back in the truck, an assortment of rock chisels, and the Estwing pry-bar, the one that has the pointed chisel end on the bottom, and the flat L-shaped head on the top. Moreover, the “L” can be used to scrape or be used as a chisel as well to hammer into a crevice—absolutely beautiful little tool.

Having rounded up the tools, I hustled back to the site. The most amazing part was that once I started to chisel out bedrock chunks, the original bedrock was indeed solid, but there was a natural cement of fine-grained, crushed black slate that had been running with the gold in the stream channel that created a perfectly camouflaged matrix, the matrix rock hard as well. In this way, Nature had hidden the original crevices perfectly.

Using hammer and chisel, I worked my way down well outside the edge of the signal’s midpoint. I usually had to go down two to four inches to get below the signal, but then I’d insert a longer chisel and reef on it until the piece of bedrock and matrix popped out. Sometimes the piece would flush up in the air just like a game bird! (It makes sense now why my partner was on point like a bird dog.) After the first nugget flew, we made sure to block the flight path with a large gold pan. We couldn’t risk losing any nuggets in adjacent cobble piles.

After recovering the nugget-rich matrix, I took the chunks and carefully tapped on them until they started to fracture and crumble. (As the matrix and the bedrock were of the same hardness, I never knew where the piece was going to fracture.) Having reduced everything to small pieces, I passed them under the coil to pinpoint the gold-bearing ones.

After tapping away to remove the remaining residue, the gleam of gold was unmistakeable. Moreover, all of the nuggets had wonderful character, nothing flat, featureless or hammered. It was incredible fun liberating a dozen of those long hidden multi-gram nuggets.

Did I smash any fingers while reducing the chunks? Absolutely. Did it hurt? If a fingernail goes black and falls off later, would that qualify? Regardless, the gold adventure was well worth the effort.

In another instalment, I’ll talk about detecting the test-piles farther up that same placer claim and what I found in them.

All the best,
