Re: Soil samples for placer indication

Haul samples or haul water? PickaxeCA brought up the question on another thread. It's an important consideration. In my experience, I have found that the compromise is a mid-point indoors shelter where the environment is stable. Even just a canvas wall tent where things can be setup in an orderly ma...

Re: Soil samples for placer indication

Auger; Augers are an option for soil sampling. The trade-off is that you get a scrambled sample depending how much you advance the auger before pulling a sample. The sample will be scrambled to a degree anyway regardless of how often you pull a sample because it is impossible to avoid dragging the w...

Re: Soil samples for placer indication

Penetrometer; Another thought... I have been involved in exploration for GOLD as well as mining for a long time. One of the methods used in soil sampling is a penetrometer. It's basically a pipe, sometimes with a liner that is driven, usually by a machine into the ground. With it, you can get a vert...

Re: Soil samples for placer indication

Hi Slatco, For clarification, 1 ppm = 1 gram per metric tonne. Because one gram is defined as one cubic centimeter of water, that's 1 cubic meter of water or 2205 pounds (avdp) by weight. :) I presume your sample was a bulk sample taken over a wide area. I also presume you are planning on testing th...

Re: Small scale hard rock mining and prospecting

Economy of scale: In 2009, after getting washed off East beach at Nome the prior year, I arrived at McGrath, in the interior of Alaska. I was waiting for my baggage as all of the other incoming passengers. I was keen to watch the locals as they observed me with that "Oh no! Not another one of those!...

Re: Small scale hard rock mining and prospecting

Anomalous GOLD; Prospectors are faced with an awesome challenge to find GOLD. That's because we are looking for a needle in a hay stack even in areas with anomalous amounts of GOLD. Consider a prospective area to have one part per million - an amount 250 times more than the "relative abundance" of G...

Re: Small scale hard rock mining and prospecting

The chase is on; Where do we begin the chase? The short answer is; "with a discovery". The statement has been made that "every creek and river in Alaska has GOLD in it". Just for the sake of argument, let's assume it's true. From casual observation and listening to all of the discoveries gone bad an...

Re: Small scale hard rock mining and prospecting

Prospecting or mining? Prospecting begins way before a shovel hits the dirt. Research needs to be done on areas known to have GOLD mineralization, Study of maps that show GOLD mining districts will be a guide. Not all mining districts are GOLD mining districts. :o The other option is "Wild cat" pros...
