Pieces of the puzzle; When asking a question of this group and the group experience, the question may be viewed by many (millions) of viewers that are not members and therefore cannot reply. Considering the breadth of experience of the limited number of members of the group and the possibility one o...
A prospector's intuition; This doesn't support the narrative but the evidence from past and present GOLD prospecting seems to support the narrative that soils are used to point uphill/upslope to find lode deposits and not downhill/downslope to find placer deposits. Being a good prospector is like be...
The age of Discovery; It's easy for GOLD prospectors to become "myopic". It's a case where we develop a view of the world around us based on a narrow view formed from our limited "experience". For example, in my early years, when GOLD prospecting and spending hours digging and scraping dirt, searchi...
To Slatco's question; I have never used or done soil sampling to find or locate a placer GOLD deposit and yes, It is an interesting question! Why not? The answer to "Why not?" is related to several factors that affect the relevance of soil sampling in general and the probability of discovery of a "p...
I found him on researchgate.com; Robin Grayson profile: Robin is a polymath with interests spanning: ECOLOGY: EIA & ESIA; herpetology (especially Triturus), freshwater invertebrates (cladocerans; Hydra, beetles etc.); pond ecology & pondscapes; urban ecology; urban forests, air quality; groundwater;...
Introducing Shawn Ryan; Shawn Ryan used a tulip planter to discover GOLD in the Yukon! :o Watch this: The second gold rush - a prospector's perspective: Shawn Ryan at TEDxWhitehorse https://www.youtube.com/watch?v=9bIIskBJVvg I have posted many times before about Shawn Ryan and his early years. Usin...
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...
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...
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...
