nINTRODUCTION
The Jock claim group is located between 57013 and
57017 N latitude and 126053 and 126057 W longitudein the Toodoggone River map sheet area N T S 94E
2W and 7W Omineca Mining Division see Figures 1 and 2
Topography is moderately rugged Approximately two thirds
of the property lies above tree line
Access is by plane from Smithers to Sturdee Valleyairstrip a distance of 280 kilometres and from the
airstrip to the property by helicopter a distance of
10 kilometres
The claim group is comprised of the following claims

The claims are owned and operated by SEREM Ltd Pre
vious work is described in the assessment report submitted
by SEREM Ltd in March 1981
o
During the 1981 field season geochemical soil and
silt sampling along with minor mapping and prospectingwere carred out on these claims The Itsch claim was staked
to cover an area of favourable geology 253 soil and silt
and 5 rock samples were analysed for gold and silver and
copper lead zinc or molybdenum The purpose of this
survey was to test areas of anomalous silt values or
favourable geology see 1981 report

n GEOCHEMICAL SOIL ROCK AND SILT SAMPLING
Soil samples were taken at 100 to 150 metre intervals
on traverses at approximately constant elevation Pacingor Topofil was used to control distance and the localities
were plotted on a 1 10 000 scale topographic map Out
crops and talus were examined while collecting the soils
and samples with favourable characteristics were sent for
analysis
For the grid survey a baseline was set with compass
and surveyor s chain and picketed every 50 metres Soil
lines were run with Topofil and compass using the baseline
as control
o
Soil was placed in brown paper envelopes and
characteristics such as depth of sampling horizon colour
grain size and amount of organic material were noted
Soils on the talus slopes have no B horizon therefore the
C horizon was sampled The grid area is a plateau of poorlydrained soil developed on felsenmeer or gravel Samplesare a mixture of A and C horizons
Silts were taken from streams draining the Itsch
claim area at intervals of approximately 150 metres
Samples were collected from active material that is
under flowing water and placed in brown paper envelopesThe stream gradient is moderate to gentle and the flow
rate was moderate to slow

o GEOCHEMICAL ANALYSIS
Samples were sent to Min En Laboratories and were
ana lysed for gold silver copper lead zinc and
molybdenum The analytical procedure for each element
is briefly described below
The samples are dried at 950 C Soil and stream
sediment samples are screened by 80 mesh sieve to
obtain the minus 80 mesh fraction for analysisThe rock samples are crushed and pulverized byceramic plated pulverizer
For gold a suitable sample weight 5 or 10 gramsis pretreated with HN03 and HCI04 mixture
After pretreatment the samples are digested with
Aqua Regia solution and after digestion the samplesare taken up with 25 HCl to suitable volume
Sample solutions are prepared with Methyl Iso ButylKetone for the extraction of gold
o with a set of suitable standard solutions
analysed by Atomic Absorption instrumentsobtained detection limit is 5 ppb
gold isThe
For silver copper lead zinc and molybdenum samplesweighing 1 0 gram are digested for 6 hours with HN03and HCI04 mixture
After cooling the samples are diluted to standard
volume The solutions are analysed by Atomic
Absorption Spectrophotometers using the CH2H2 AirFlame combination for silver copper and lead The
C2H2 N02 mixture is used for molybdenum

GEOCHEMICAL RESULTS AND INTERPRETATION
Contour soil and stream silt analyses are plotted on
Figures 3a for gold and silver 3b for copper and molybdenumand 3c for lead and zinc Threshold values are underlined
and anomalous values are circled
Gold is marginally anomalous in a few areas the
highest value in soils is 130 ppb Silver is anomalous
on the western portion of Jock running greater than 3 0
ppm silver in several samples Elsewhere silver is
anomalous in a few isolated areas Copper is generally in
the background range except for a few marginal anomalies
on Jock 2 Lead anomalies correspond to gossan areas
and are enhanced by residual enrichment in these stronglyleached soils Lead values which occur on the northwest
Jock 1 claim may be related to galena bearing veins in
the volcanics Molybdenum is marginally anomalous on
Jock 2 and in the background threshold range elsewhereo
The following table lists descriptions and analysesof rocks collected on the contour traverses Locations
are plotted on Figures 3a to 3c

Augite porphyritic andesites Takla group contain
several fracture controlled zones of quartz calcite

The area is virtually barren in lead and molybdenumCopper is weakly anomalous and coincides with silver
anomalies Two unrelated gold anomalies also occur in
the area In general the geochemistry does not indicate
any economic mineralization

Marginal anomalies in gold silver copper and lead
occ r in the silts taken from streams draining the Itsch

samples anomalies in the other elements are more
erratically distributed Highest values are 270 ppb gold3 0 ppm silver 140 ppm copper 89 ppm lead and 197 ppm

o CONCLUSIONS AND RECOMMENDATIONS
The Jock claim group is underlain by volcanic rocks
which have been subjected to intense hydrothermal altera
tion A large highly leached gossan formed by later
oxidation of disseminated pyrite affects the geochemical
signature of the area by enhancing certain elements such
as lead and diluting others such as copper Geochemical
sampling ha9 outlined an area on Jock 2 and one on the
Itsch claims which have anomalous precious metal values
These areas should be mapped and prospected in detail
Further work would depend on these results
