Biogeochemical survey, NTS 93A/12, QR deposit, central British Columbia, 1988
(requires an Internet connection)
Douglas fir tree tops were collected from 94 sites within a six square kilometre area approximately 140 km southeast of Prince George in central British Columbia. The study area was centred on the Main Zone of gold mineralization of the poorly exposed QR (Quesnel River) deposit. The sampling was carried out during the morning of April 27, 1988. In total 103 samples were collected, including a few from distant areas to determine background levels of elements. An interpretation of the work can be found in Journal of Geochemical Exploration, v.34.
Samples were collected at intervals of approximately 200 m (100 m on one line) along 12 lines 200 m apart. The length of line varied from 500 to 2300 m. A helicopter was used to obtain the samples, with the sampler, who was harnessed in, leaning out over the skid and snipping off the top 0.5 m of the tree.

The geographic extent of the survey is defined by the following polygons:
Covers part of NTS 93A/12 (Hydraulic) north and south of the Quesnel River in central British Columbia. It is located approximately 7 km west of the town of Quesnel Forks and approximately 2 km west of the junction of the Quesnel River and Maud Creek.
