INTRODUCTION

Extensive reconnaissance assessments of the mineral resource potential
of the Colville and Okanogan National Forests in northeastern Washington
were conducted during 1979-1982 by a private consultant A.R. Grant,
under contract with the U.S. Department of Agriculture, Forest Service.
These forests occupy large parts of Pend Oreille, Stevens, Ferry, and
Okanogan counties, and smaller parts of Whatcom, Skagit, and Chelan
counties adjoining Okanogan County in the Cascades. Sampled terrain also
included the Kaniksu National Forest in Pend Oreille County and one
stream bed of the Kaniksu in adjacent Bonner County, Idaho. (Figure 1)

Two unpublished reports resulting from the assessments (Grant, 1982a,b)
list a total of 3,927 analyses of gold, silver, copper, lead, zinc,
molybdenum, tungsten, and uranium content of stream sediment and bedrock
samples collected at widely dispersed sites in the three National
Forests. This report makes this important body of work available in
digital form on diskettes, to enhance manipulations with computer
spreadsheets, geographic information systems (GIS), and digital spatial
analyses. This will allow for utilization of data by modern day
explorationists and by the general geodata user community.

The authors wish to acknowledge the considerable assistance of Rod
Lentz, Okanogan National Forest staff geologist, Omak, Washington, in
facilitating access to the unpublished reports and other documents. We
are indebted to Sam Gehr and Robert Vaught, Forest Supervisors of the
Okanogan and Colville National Forests (USDA), respectively, for
permission to publish the data. Robert E. Derkey, Washington State
Department of Natural Resources, Spokane, Washington, provided software
and digitizing facilities, and Pamela Derkey, USGS, Spokane, assisted
with preparation of metadata. J. Douglas Causey, USGS, Spokane made maps
used for comparisons.

# DATA DIGITIZATION

The first step in the conversion consisted of entering the analytical
chemistry data into a desktop computer spreadsheet (Excel97, Microsoft
Corporation, Redmond, WA). In the resulting digital table, fields
consist of forest name, USGS topographic quadrangle name, sample number,
sample description, sample type (whether stream sediment or bedrock
sample), and analytical data for eight elements. Explanations of these
categories can be found in Appendix 1. Analytical data are reported in
parts per million (ppm) except for gold, which is reported in parts per
billion (ppb). Where necessary, troy ounces per short ton were converted
to ppm by multiplying by 34,286. The numbers of sample results on the
spreadsheet are tabulated by category below.

Total 2,184 1,745 3,929

boundaries are shown by outline.

The next step consisted of determining the latitude and longitude
location of sample sites (points) plotted on Grant's original mylar base
maps. Software employed in this task (GS-MODS, Johnson, 1987) assigns
each data point a discrete sequential digitizer number. The sequential
numbers were manually linked to the spreadsheet data as the digitizing
proceeded. The digital data-point coordinates were then plotted on maps
in Universal Transverse Mercator projection (zone 11, North American
datum, 1927, central meridian 117.00 degrees, 1866 Clarke spheroid) at
scales matching those of the original maps. Comparison of sample site
locations on the two sets of maps revealed average differences of +/-
349 feet (106 m). Such large discrepancies are believed mainly
attributable to 1) distortions introduced in the process of photographic
reproduction and compositing of numerous 1:31,680- and 1:63,360-scale
field sheets during construction of mylar base maps[^3], and 2)
incomplete specifications available for the projections of original
maps. Users attempting to recover more precise sample locations would be
well advised to refer back to the original mylar maps, currently
archived at the Okanogan National Forest headquarters, Omak, WA. Users
can re-create the map coverage by using the x,y-coordinates in Table 1
(Appendix III).

Three files have been created and recorded on one 1.44 MB diskette. A
list of the files and the location where they can be obtained are found
elsewhere in this report.

# CHEMICAL ANALYSES. 

As reported by Grant, samples selected for analysis were first prepared
by sieving to minus-80 mesh (stream sediments) or by crushing and
pulverizing followed by sieving to --100 mesh (rock samples). At least
two commercial laboratories performed the analyses, TSL, Spokane,
Washington, and Chemex Labs, Vancouver, B.C., with the latter carrying
out a majority of the work. Both trace element and ore grade assays were
performed.

The Forest Service provided information to indicate the analytical
methods and standards applied[^4]. A one-gram sample underwent a
perchloric-nitric digestion. Analysis for copper, molybdenum, lead,
zinc, and silver was performed by atomic absorption spectrophotometry
(AAS). Backgrounds were corrected for non-atomic absorption for lead and
silver. For gold analysis, a five-gram sample was ashed at 550^o^C to
destroy any organic material. The sample was digested to dryness using
aqua-regia and re-dissolved using 25% HCl and then extracted as a
bromide complex. Analysis was completed using AAS with a correction
applied for background. Uranium analysis was performed by the
fluorometric method on an aliquot received from the perchloric-nitric
digestion. Tungsten analysis was performed on a 0.5-gram split using
pyrosulfate fusion with an overnight extraction followed by complexing
with 3,4-dithiol for a colorimetric finish. The following minimum
detection limits are routinely achieved on solutions read for a
particular element: copper, lead, molybdenum, tungsten, uranium, and
zinc, 1 ppm; gold, 0.01 ppm; and silver, 0.1 ppm. Detection limits vary
slightly depending upon other elements determined from the same
solution. Upper limits are essentially 100% for all metals, however,
accuracy may suffer with higher dilution factors. No data is available
to indicate samples exceeding 1000 ppm were re-run to improve precision
as recommended by Chemex Labs.

Sampling procedures and integrity of laboratory results are always
important considerations. The following comments are quoted from the
mineral assessment reports.

*...."Stream sediment samples were collected from all major accessible
drainages and, in areas of high density sampling, from minor drainages.
Care was taken, wherever practical, to avoid contamination of stream
sediments by man-made objects such as up-drainage metal culverts. Where
samples were taken from drainages with suspected up-stream
contamination, the possible contamination factor was duly noted. In a
few instances, fine-fraction sediments could not be found and, in those
cases, no sample was taken. Rock chip samples were collected from
mineralized or altered outcrops and mine workings where analytical data
would be of aid in delineating target areas for future
activity.\*\*\*\*\*\* The contractor's responsibility for the samples
designated for analysis ended upon delivery to the Forest Service. A
separate contract existed between the Forest Service and the analytical
laboratory. Unfortunately, during the summer of 1980, serious problems
as to sample preparation and questionable analytical results became
evident. Several meetings with the laboratory resulted in an improvement
in performance. However, umpire analyses of selected samples indicated
possible serious accuracy problems for Au, Ag and W. As a consequence,
all stream sediment samples collected during the contract were
reanalyzed for Au, Ag and W in a laboratory having a high performance
rating with the mining industry... "* (Grant, 1982a,b, p. 4-5).

[Rock/Sed]{.underline}---Type of sample: rock sample (R), or stream
sediment sample (S)

[Element data]{.underline} for gold, silver, copper, lead, zinc,
molybdenum, tungsten, and uranium:

The following conventions are used in reporting the the element data.

"-999" indicates *no trace element data were provided; reason is
unknown*

"-99" indicates insufficient sample for analysis

"-" (minus sign) value reported is below the lower detection limit for
the element. For instance, a "\<10.0" would be reported as --10 but 10.0
would be reported as 10. Likewise a \>100 would be reported as 100.

For values that exceed the upper detection limit for the trace element
(e.g. +10,000 ppm for Zn), the assay value is reported at that detection
limit value (e.g. 10,000 ppm for Zn). Values reported above the
"apparent" upper limits are interpreted as resulting from analysis
obtained from separate laboratories.

#  Description:

#  Abstract:

#  Unpublished mineral assessment reports of the Colville and 

#  Okanogan national forests (Chelan, Ferry, Okanogan, Pend 

#  Oreille, Skagit, Stevens, and Whatcom counties, WA) contain 

#  data on 3,934 samples analyzed for gold, silver, copper, lead, 

#  zinc, molybdenum, tungsten and uranium. Data presented here 

#  were obtained by R.A. Grant (1982a,b) for an assessment of 

#  the mineral potential of these national forests during 

#  1979-1982 under a contract from the USDA-Forest Service.

#  

#  Purpose:

#  This dataset was developed to provide geochemical data for 

#  the Colville and Okanogan national forests, WA for use in 

#  future spatial analysis by a variety of users.

#  

#  This database is not meant to be used or displayed at any 

#  scale larger than 1:63,360 (e.g., 1:62,500 or 1:24,000).

#  Process_Step:

#  Process_Description:

#  Geochemical sample sites were digitized from the original

#  stable-base maps (assumed to be in a UTM zone 11 map 

#  projection) into GSMODS, ver. 1.01 (Johnson, 1987) as 

#  points.

#  

#  These point data were output to Arc/Info GENERATE-format 

#  files using the GSMGIS utility (G.I. Selner, written 

#  communication, 1994) and then imported into an Excel97 

#  file format.
