Rapid surface water analysis for mineral exploration
Rocks, soils and the sediments found in stream beds are the most common
materials collected by explorers looking for new mineral deposits. But in
areas where access is difficult, like the coastal mountain ranges of
British Columbia, thick forests on steep mountainsides make it difficult to
sample these materials.|
Water, however, is plentiful and can carry tiny amounts of metals and other
pathfinder elements away from the source of the metals. Mineral explorers
can trace these back to the source but don't often sample surface water
because it is perceived as difficult to sample and water analysis at
commercial laboratories is quite costly.
Until now. As part of an innovative project supported by Geoscience BC
and industry, researchers Ron Yehia and David Heberlein have demonstrated
that field-portable photometers can provide good quality, same-day water
analyses, at a lower cost and with shorter turnaround time than a
Portable spectrophotometers, or photometers, measure light as it passes
through a water sample. By adding a few drops of various chemicals to each
water sample, testers are able to detect tiny quantities of metals, from
aluminum to zinc.
During August and October 2014, researchers Yehia and Heberlein collected
water samples around the Poison Mountain copper-gold porphyry prospect,
about 100km northwest of Lillooet in southern British Columbia. They tested
the effectiveness of the Palintest Photometer 8000 by comparing results
from water samples analyzed in the field with laboratory analyses of the
Their results show that a field-portable photometer can be an effective
tool for obtaining rapid and low cost measurements of a relatively small
selection of elements in surface waters, providing an additional tool for
explorers searching for surface and buried mineralization.
