HISTORY OF MINES IN NORTHWEST TERRITORIESA must read - chalked full of intel pertaining to the mines of NT.

SIMPLE ANALYSIS - BAR BET MINE
Interesting name - most likely was sparked by a few drinks at a local saloon - lol
Important takeaways ?
assumed vein gold 40 ft long ( sounds like they found both ends ) was it really a vein ?
If both ends are found - how elese could this vein have developed ?
Second biggie ?
Yellowknife super group - greywaxkes ( clays reconsolodated ) volcanics, greenstone, veins
This super group sounds like a miriad of rocks ( heinz 57 rewelded ) own opinion.
Yellowknife super groups appear quite often - amongst the mines. Though generic it still provides an insight into the geology if one pulls apart the exact compositions of the rock per each region - seeing what was the perdominate feature of the super group..
Greenstone rocks = chlorites - chloride salt waters
Greywacke - another variety of rocks ( fines ) welded into a clay consortium.
Volcanics - all depends on what the volcanics look like - were they fines - remants ?
Veining - they found both ends - to me - it suggests - was it really true blue geothermal vein ?
Hand cobbed - certainly points to very near surface - was amendable= small picks / shovels
Big gold - small vein -
Smoking gun ?
there should be a feeder vein that prompted this 40 ft vein.
Where is the feeder vein that allowed the branching ?
Rumors - it was rumored thery stole the gold from another mine.
Such would easily be assumed if the veining had no feeder main vein.
BUT.... what if this vein was formed by salt carbonates creating greenstone mixing with the volcanics ?
Yet... the southern portion of vein was trunkated - with a fault.
Could also be - the fault trunkated and pinched out the vein - which could stil lpoint to geothermal.
Anyways.. it is an interesting mining story.
I would have loed to see the actual ternching and see exactly what the ore really looked like.
Pictures are far better than second hand iterations.
What i have come across is a very intersting above grade picture of an unknown location with in the NT -
DOES ANYONE SEE ANYTHING INTERESTING IN THIS PIC ?
First thing that caught my eye was... the conglomerates - yeah... looks like - loose rocks were encapsulated with in a grewacke or claystone group - that suggests watershed along with carbonates and csilt clays were once very dominate in the forming of this rock class.

BAR BET MINE
Years of Primary Development: 1938-1941
Mine Development: high-grade trenching
Years of High-Grading: 1938-1941
High-Grading: 331 oz Au
Introduction This small high-grading gold operation was located on the south side of Indin Lake, 193 kilometers northwest of Yellowknife, N.W.T. It has not been visited by the author of this report. History in Brief Gold was discovered on the Barker vein in 1938 by prospectors with Territories Exploration Limited and the ‘Anna’ claims were staked. Some gold was high-graded from the showing by their crews during 1938-1939.
In 1940, Peter and Charles Schwerdt re-staked the property and hand-cobbed more gold at these claims. It was rumored that they had actually stolen the gold from the Con and Negus Mines in Yellowknife. Geology and Ore Deposits 1 The area is underlain by foliated, dark green, Archean andesitic metavolcanic rocks of the Yellowknife Supergroup.
The main showing, the Barker vein, is a 40 foot long, quartz-carbonate vein. The vein is truncated on the southern end by a fault and ends abruptly in soft grey schist in the north. The vein is one foot wide in the southern portion and widens to 3 to 6 feet to the north. All of the gold was extracted at the intersection of the south end of the vein with the truncating fault.
Territories Exploration Ltd. (1938-1939) Crews with Territories Exploration Limited were at work during 1938-1939 trenching the Barker vein. They hand-cobbed 1600 pounds of ore and were able to extract 83 ounces of gold by mining a pipe-shaped oreshoot 1 foot in diameter and 10 feet in length.
The company abandoned the claims in 1940 because of war conditions (Lord, 1941). Pete and Charles Schwerdt (1940-1941) In 1940, the claims were re-staked by Pete and Charles Schwerdt, and an additional 248 ounces of gold were recovered from the Barker vein by 1941. Exploration Since Mine Closure
The claims were diamond drilled and trenched by American Yellowknife Mines Limited in 1945-1946, returning interesting gold values (National Mineral Inventory). The property was re-staked as the ‘Vidie’ claims by G.E. Swanson in 1982, followed in 1985 as the ‘Barker’ claims, and in 1992 as part of the ‘Hela’ claims. In 1984, the old trenches were mapped and sampled, and it was reported that further work was merited (Day, 1984; Flood, 1994).
I'll remain quiet now - lol
Hwy.. i like studying geology.
I find the NT extremely interesting.
It's massive and kisses B.C. with A SHARED - cadellera range .
Lots of interesting geology.
Cheers....
