Crevicing Still Remains One of Your Best Gold Recovery Methods (Part 6)
(This is what your crevicing or gold "sniping" efforts are all about.)
As I continue with this series of posts on crevicing or gold "sniping," please bear in mind that the post's title is not targeted toward large-scale or commercial mining enterprises, but is oriented toward you, the individual gold prospector and miner. That said, let's move on and talk about dry placer crevicing a bit more.
6. More on the Dry Placer Factor
I mentioned in my previous post that the main advantage to crevicing dry placer locations is accessibility. This is due primarily to the lack of water in most desert or dry placers...a two-edged sword when it comes to crevicing and small-scale gold mining in general.
Let's look at the main disadvantages associated with crevicing in dry placers:
- Lack of water. A friend and an enemy of sorts, the absence of water in dry placer bedrock areas severely restricts your ability to sample properly. Sure, you can dry pan material (a very inefficient way to pan or sample, by the way) but in certain instances once you start rooting around in dry placer bedrock crevices, chances are some of that material is going to come up damp. When this occurs, you either have to dry that creviced material out and run it through a dry washer, or get it to water (wash tub, water recycle unit, etc.) to pan it or process it properly.
- Poor gold visibility. The pure and simple fact is that most creviced gold doesn't show up well in all that sand, dirt, gravel, and dusty grit that typify the majority of dry placers. This is especially true of the finer or smaller pieces of dry placer gold. Large or medium nuggets are a rare event in crevicing in general, so don't expect to be able to easily "eyeball" big, gleaming pieces of placer gold in creviced material from dry placer bedrock. (If this does happen, however, you're in fat city my friend.) By contrast, in crevicing underwater placers, you can spot even very small pieces of placer gold resting atop bedrock or crammed into a crack or crevice in most instances.
(Even the smallest bedrock crack or crevice can trap gold.)
- Erratic or "spotty" gold deposition. Although not a factor in each and every case, gold deposition in dry placer areas tends to be very hit or miss. As I mentioned before, this is due primarily to the intermittent flow of water in most dry washes, gullies, or arroyos in dry placer districts. So that bedrock crack or crevice you just spent 30 minutes cleaning out may, or may not, carry any gold. Remember this fact...it'll save you some heartache and frustration. Still, you must approach each likely looking dry placer bedrock crack, crevice, or depression with the same care and level of effort you would anywhere else, wet or dry.
Best of luck to all of you and keep coming back. I depend on your support.
