RE: Making Sense of It AllLet me say firstly, Bumblebee, that if I had never read a thing about glaciation in the
Yukon or why the direction of valley and streams would play any impact, I certainly
wouldn't have gotten as much out of it the first time round as you have here, my friend;
you rock (figuratively spoken.....<grin> )
I appreciate your input here, Scottie, and am constantly learning from what you have
to add to this conversation we got going here. Where you have stated " Your guess is
as good as any. We'll just have to wait patiently for this story to unfold", is an accurate
statement. As much as we look through the maps and note the directions of iceflows
and then gather up all the other limited info we can get our hands, on, we still will come
up way short on what all info the geologists and companies are accessing to determine
where to place their stakes in the ground.
This is also one of the reasons why I really appreciate Mr. Bremner's willingness to
help educate or provide his view and help educate us here.
It is quite obvious that the GSR team as a whole, are in tune to the fact that
Knowledgeable Shareholders = Strong Hands.........
With that said, Scottie, I would like to comment on a couple of your excellent questions
and thoughts.
"It's been stated that larger, angular nuggets implies they haven't travelled far. I just
wanted to clarify that this conclusion comes from the fact that the smaller and rounded
they are, the more likely they were probably exposed to glacial erosion or melt water
erosion and thus the higher chance they have moved farther away from whence they
initially came, correct? "
On Sept 22, I posted a statement made by Mr. Bremner which confirms this theory, BB.
He stated,
"and especially when the nuggets in creek are coarse and angular and clearly haven't
travelled very far."
He has also added ...... Much of the recovered gold contains large, rough nuggets. Many
of the nuggets are encased or are attached to quartz and other country rock.
The comment that nuggets that have travelled a long distance are rounded and those
that have travelled a relatively short distance are angular, is correct. Gold is no different
from other detrital minerals to this respect.
Mr. Bremner has since then expanded on this topic with me to include the following:
Gold nuggets are eroded out of bedrock and don't travel very far because they are
heavy and difficult for water to move. They sink to the deepest parts of stream channels,
get trapped in fractures in the creek bed or behind shoulders. The reason gold nuggets
are not found in Ontario, Quebec and NWT, even though these areas are very rich in
gold, is because glaciation has scoured the bedrock and bulldozed away all the nuggets
that have accumulated in the streams. "
BB stated, "streams running tranverse to the ice flow containing gold are one of the
best indicators that the gold is quite close, correct?"
On Sept 26th I posted from an unpublished article provided again by Mr. Bremner which
stated,
"the gold has been eroded primarily from quartz veins and stringers which strike
perpendicular to the flow of the creeks.
I mentioned the other day when we were speaking on this and Scottiepimps shared with
us the example of the "broom effect" with the glaciers sweeping the gravels into the
valleys, and I stated that it was my belief also that in some scenarios that rather than
the sweeping effect, that, in fact, those deep narrow valley walls acted as a shield or
barrier for the deposits that lay within them to be moved and redeposited elsewhere.
If you can imagine lands deep in the valley running, say, north and southerly, and
then iceflows way up above running perpendicular, then any movement would be
stopped or prevented on the lands below once they hit that valley wall. I have been
receiving some great info from Mr. Bremner and will provide one of his comments to
address this question, BB....
"In the Livingston area narrow canyons like Lake Creek and Cottoneva Creek that
cross Goldstrike's claims, would have escaped the main glacial flow down the Big
Salmon River Valley. They may have been full of ice, but if the ice remained static
and didn't flow, the nuggets would have remained in situ.
McConnell glaciers moved over the area from the south-southeast, preserving the
placer gold by covering the creeks with variable thicknesses of till. The gold has a
high purity of 860-895 fineness. The amount of gold reported from the Livingston
creeks is 50,000 troy ounces. However, much of the gold produced by the "old-timers"
went unreported and, because of this, placer gold production is estimated to be
closer to 100,000 troy ounces. "
Livingston Creek is bigger, but also tranverse to the main glacier occupying the Big
Salmon river valley. The report states that glacial till preserved the gold in the main
Livingston Creek valley. Underground placer mining has been carried out in Livingston
Creek, using tunnels to mine beneath the frozen till.
BB stated, "In looking at the maps, my interpretation would actually be that Northern
Predator (Tiger I think you mean) appears to have the best position in the Livingston area,
based the number and direction of the placer streams. However,, as Scottiepimps
mentioned, it would also depend on the size of the nuggets found too................."
This is where I would like to point out here, Bumblebee, that you have really brought
out a great point here with that comment. Again, all of us are accessing what little
info we have access to and
