Your description sounds more like a Kimberlite deposit that one from the Big Blue. Sorry for not reading all the posts in this thread before replying.hmmm said:Klondike
THAT IS VERY ITERISTING
my blue lead stream bed is uique,. it runs due south, it starts near the top of a volcaic crator, just in the troat where a sheer also runs north / south. the blue ground runs for about 2 km then it just dissapears, it looks like the end of a old mine. this is where it gets interistsing, the empty streambed flows for 2 more km then drops into the sea. it has beec cut off as is the land was cut in half. the fine gold FROM THE BEDROCK EXPOSED BELOW THE END OF THE BLUE HARD PANN is very unique. very rough edged.

Kimberlite often forms chimneys in volcanic areas. It is noted for gold, platinum, iridium, osmium, palladium, and other heavy metal production. I haven't seen the entire analysis you had done, but the fact there is platinum, gold and silver concentrations strongly suggests something similar to a Blue Smoker found off the Souhern Oregon/Northern California coast line: known to be very rich in metals and sulfides.
Kimberlite is also noted for diamond production. It is possible some of the "quartz" crystals you are finding may be other than "quartz". Kimberlite is named for Kimberley, South Africa: a center for very deep mining of both gold and silver, but also platinum, palladium, etc.
i am not located in any of those archons,Astrobouncer said:Hmm, some of those look awfully close in clarity to the google image results for 'Alluvial gemstone images" such as this one:

Look closely and see if you see the common crystal shape of diamond which is octahedral.

I would take a large sample to a geologist or gemologist and see what they say, or even send them off somewhere. Are you located near any of those archons I posted above?
THANKS YUDAyubagold said:I agree that some of those crystals have awfully symetrical sides. A simple hardness test may tell you what you have. I've got some industrial grade diamonds that I'll try to post photos of for comparison...maybe your gold and silver should be an afterthought to diamonds?
your pictures dont work, you may need to shrink them first.liseehw said:Every other year we head out to the Island.. I think we are ready for another trip
We would love to come by and check out your caves.
Here is a photo of the cave we found last summer in the kootenays.
