The reanalysis of archived sedim
ent samples has been sponsored by G
eoscience BC
since 2007. T
hese programs have significantly enhanced the B
C R
GS
database by providing a w
ide range of new analytical inform
ation at improved detection levels.
McL
eod Lake (N
TS
093J):
1145 samples analyzed for 35 elem
ents
by instrumental neutron activation
analysis (INA
A).
Lardeau (N

1224 samples by ultra-trace aqua-regia
digestion (0.5 g) ICP
-MS
technique
for 53 elements .

Stream
-based sample collection w
as carried out in the summ
er of 2012. M
oss-mat sedim
ent and water sam
ples were acquired
from over 700 sites. T
he sediment sam
ples have been analyzed for base and precious m
etals, pathfinder elements and rare earths
by an ultra trace aqua-regia digestion ICP
-MS
package and INA
A.
Waters have been analyzed for pH
, conductivity and fluoride.
To
further augm
ent N
VI's
geochemical
database, till
samples
collected in the 1990s as part of the northern Vancouver Island
drift prospecting program w
ere recovered from storage and a
portion of each sample as been recovered for analysis by an
ultra-trace aqua-regia digestion ICP
-MS
package for 53 elements.
