INTRODUCTION
In July, 1980 a soil geochemical survey of the Zen
1 mineral claim was undertaken on behalf of St. Joseph Explorations Limited.
The purposes of this survey were to define and .evaluate known molybdenum mineralization within the property.
Four field personnel, under Mr. D. Miller's and the
writer's
supervision, flagged
all
grid
lines
and
collected
the geochemical samples. A Hughes 500C helicopter and a Beaver
airplane on floats were used to mobilize, service and demobilize
the field camp. This program was carried out between July 18th
and 31st.
This report contains the results of this exploration
program with recommendations.
LOCATION and ACCESS
The Zen 1 mineral claim is situated 45 km east-northeast of Atlin, B.C. at the southern headwaters of Zenazie Creek.
The claim is located at latitude 59O4O'N by 132O57'W longitude
(N.T.S. 104N/lOW).
Access is best gained by helicopter from Atlin, B.C.

PHYSIOGRAPHY
The
property
straddles a northerly trending cirque
approximately 3 km northeast of Weir Mountain. Relief within
the claim is moderate to steep. Elevations range f r o m 5,000
to more than 6,000 feet A.M.S.L.
Vegetation consists of alpine grasses and low shrubs
typical of the mountainous Atlin region.
Soils are poorly developed on the steep slopes due
to
recent glaciation. Ice movements was primarily north and
eastward.
CLAIMS STATUS
Under the terms of an agreement with Comaplex Resources, St. Joseph Explorations Limited has obtained an interest in this 20-unit property.
The Zen

this claim is validate until its anniversary on July 6th,
1982.
HI STORY
This
1978
property
was
staked by
Comaplex Resources in
to cover known molybdenum and beryllium occurrences. Pre-
vious work
in the area consisted of geological, geophysical
and topographic surveys undertaken by Canadian Johns-Manville
in 1971
-5-
GENERAL GEOLOGY
The Atlin map-area is underlain by volcanic, sedimentary and metamorphic strata ranging in age from Mississippian
to Quaternary. Three main depositional events occurred during
the Mississippian-Permian, Triassic-Jurassic and Late Tertiary
time.
Major
intrusive
Permian-age ultramafic
events
bodies
include
followed by
the
emplacement of
the intrusions of
Jurassic-Cretaceous quartz diorites to quartz monzonites and
Late Cretaceous/Early Tertiary alaskites.
The area has been glaciated, at least, twice during
the Pleistocene. These glacial events have affected the topography and resulted in extensive till and alluvium deposits.
LOCAL GEOLOGY
The property is predominantly underlain by four granitic varieties belonging to the Cretaceous-age Surprise Lake
batholith. These varities include fine to coarse-grained alaskite, porphyritic alaskite, fine-grained porphyry, and aplite/
pegmatite. These rocks have been mapped in detail by Canadian
Johns-Manville (Aspinall, 1971).
Evidence of hydrothermal alteration within the area
is generally lacking. Locally the rocks have been
silicified,
kaolinized and/or chloritized. However, these alteration effects
appear to be more the result of saussuritization.
Fracturing within the country rocks appears to reflect
two dominant sets of regional deformation. One set trends north
-6-
to
northeast with vertical
dips while
the other set trends
northwesterly with steep southwestern dips.
Molybdenite,
wolframite,

host rocks.

GEOCHEMICAL SURVEY
A soil geochemical survey was undertaken to determine
the extent of the known molybdenum-bearing mineralization.
Between July
18 to
31, 1980 six men were employed
to carry out this work. A Hughes
Keystone Helicopters Ltd.. and
Aurora Air

a
500C helicopter, owned by
Beaver
airplane, owned by
Service Ltd., both of Atlin, B.C., were used to
and
demobilize
the
field
camp. The helicopter was
chartered to service the camp during the program.
A geochemical soil grid was established to test those
areas of the claim with known mineralization. A total of 43.1
km. of line was chained and flagged. Silva compasses were used
for orientation. Eighteen grid lines, at
surveyed
from three north-south base
200
m. spacings, were
lines. A
soil samples were collected at 100 metre
total of 357
intervals along all
lines.
Samples were collected from the
"C"
horizon and talus
fines. Due to the glaciation in the area "B" horizon soil development is negligible. These samples were placed in kraft bags
and transported to Whitehorse, Y.T.
for analysis at Bondar-
Clegg & Company Ltd.
All
samples were
dried, screened
and part of the
-80 mesh fraction was digested in hot nitric and hydrochloric
acid.

samples are
anomalous and one sample is definitely anomalous at
90N+ll4E, 92N+96E, and 102N+98E respectively.
CONCLUSIONS
Of
the three anomalous samples 92N+96E is the only
one with a coincident geochemical response within an area of
observed molybdenum-bearing float. The highest value (501 ppm
Mo), the 102N+98E sample, was collected in the cirque valley
within
an area of
glacial alluvium and
therefore the
soils
may be exotic. The 90N+ll4E sample was collected in an area
of talus and it may also be from exotic soils since no mineralization was seen in float from this locality.
Results
the area at and
of
the
soil
geochemical
survey
show
that
surrounding grid coordinate 92N+96E has the
most potential for economic mineralization. However, prospecting
within this zone found little evidence for an economic molybdenum deposit.
