NAE undertook a soil sampling program using a man-portable drill and hand auger
in February 2018 and a follow up program in September 2018.
Drilling is initially being undertaken by hand auger
teams using shell augers which have been proven very effective on the above water table drilling in obtaining excellent sample recovery and precise sample depth control.
I personally prefer the hand auger
for smaller jobs, because the auguring action can cut through some smaller roots as opposed to the clamshell.
And thus -- after briefly considering chucking my career as a starving writer and taking up a hand auger
with immediacy -- I was forced to turn to the internet.
He pulls out the gas auger--preferred over a hand auger
in areas like this with more than a foot of ice--and drills five holes for each of us.
makes a fine flat blade hand auger
in both 6" and 8" hole sizes.
Recently, the gold anomaly has been extended further south and east based on hand auger
assays results, which have just been received
The sampling has identified anomalous levels of uranium of up to 50ppm uranium from soil sampling and up to 249ppm uranium in hand auger
samples from this lake and the associated palaeochannel system.A 160-hole, 3,500m aircore drilling programme has commenced with the aim of testing the extent and tenor of uranium mineralisation and particularly its distribution at depth in the lake sediment in the areas of defined uranium anomalism.
Krevosky recently twisted a hand auger
into the earth and, with a slurp from the wet ground, pulled out a clump of dripping muck.
Following up on the previous findings, a geotechnical and hydrogeologic field investigation to evaluate the source and route of seepage flows included performing borings and rock coring with standard penetration tests; excavation to expose the uppermost two feet of the cutoff core wall; installation of piezometers, hand auger
probes; dye testing; and water quality monitoring.
