1987 EXPLOHQTION PROGRAM:
........................
In 1YB7, seven people were employed at the Continental Jade
site, including bulldozer operator D. McFarlane and manager Kirk
Makepeace.
The work program started June 15 and was completed
October 8, 1987.
Total expenditures were approximately 845,000.
txtensive work with the USH bulldozer with ripper included
road repairs and trenching in several areas.
The original
"wire-saw1' jade occurrence, from which 300 tons had previously
been mined, was extended along strike. two other areas of altered
rock with jade potential were trenched in this area, and work was
also done in the "Volcanic Ridge" area, in which tremolite had
been discovered in 1972.
The "New Jade" showing discovered in 1972 was re-examined
trenched with encouraging results.
and
Snow and ice conditions
necessitated a halt in exploration until the 1988 summer season.

could b e tested.
A drilling program in 1 9 8 8 will test t h e color
and quality of t h i s new find.
Rt t h e "New Jade" site, discovered in 1972, drilling programs
in 1973 and 1977 had established that narrow bands of high quality
nephrite occur at t h e contact of serpentine and a leucocratic,
si 11-1 i k e intrusion.
Excavation in October uncovered a band of
high quality nephrite 1 0 inches wide, but s n o w conditions
prevented definition of dimensions of t h e zone.
T h i s area should
b e further explored in 1988.
She
& exploration
program w a s successful in proving up In
t h e order of 400-450 t o n s of moderate quality jade, which, subject
t o drill testing, should provide a considerable quantity of
s a l e a b l e material in 1988.
Several a r e a s remain t o b e prospected:
1) Rdditional prospecting in t h e northern part of t h e claims
will likely uncover new boulders and in-situ jade.
Additional
ground magnetic surveys would b e useful t o delineate a r e a s of
favorable contacts of serpentine/country rock. (Refer t o 1974
geophysical maps).
The magnetic surveying would require a
picketed grid, a s compass control is not reliable i n t h e highly
magnetic area.
2 ) Several boulders of black j a d e a r e known.
Bo-Chin S u
indicated about 120 t o n s was present in t w a large boulders, north
of t h e Camp Area.
3)
Small tonnages of relatively good quality j a d e may b e
recovered from t h e "New Jade1' deposit , where Bo-Chin S u calculated
reserves of 4 1 3 tons.
It is estimated because of t h e narrow z o n e s
and steep dip that perhaps only 1 0 % of t h i s amount may eventually
b e recovered.
4i Additional diamond drilling is warranted in t h e Wire Saw
Pit a r e a and on t h e "Volcanic Ridge" deposit.
Any new areas
discovered by prospecting in 1988 will likely b e drill tested.
5 ) Drill testing of t h e Volcanic Ridge deposit (Area C of
19731, may result in t h e definition of further reserves.
Characteristically, j a d e pods may b e isolated or may b e a s
"clusters" of boulder-li ke masses.
Of t e n t h e clearing of o n e jade
m a s s will reveal other masses nearby.

P r i v a t e Report f o r t h e C o n t i n e n t a l Jade
Ltd.,
(Reproduced from S.F.Leaming,
1978).
The Trembleur intrusions a r e considered t o be partly or
wholly of pre-Late Triassic age, and a r e confined t o areas of
Cache Creek Group rocks of L a t e Paleozoic age. Much
faulting, shearing and fracturing of the ultramafic masses
was noted by Armstrong and alteration is present along many
contacts. Some is of carbonate-quartz-mariposite type which
a s Patterson (1973) noted, probably formed in Eocene t i m e
during late stage activity on t h e Pinchi fault zone. This type
of alteration is not associated with t h e formation of nephrite.
A deposit of nephrite was found by Mrs. W. Robertson
on the north side of O'ne-ell Creek 5.6 km from its
confluence with Middle River and about 8 km northwest of
t h e summit of Mount Sidney Williams. The property is known
a s t h e J a d e Queen. In a study of t h e deposit Fraser (1972)
stated, "The nephrite in this deposit occurs as veins and
lenses in a zone of foliated tremolite-chlorite rock developed
a t t h e c o n t a c t between serpentinite of t h e Trembleur
intrusions, and cherts, quartzites and argillites of t h e Cache
Creek Group".
The largest mass of nephrite, and t h e only one exposed
a t t h e surface, is on the north side of t h e creek. It is 7 m
wide and has an average true thickness of 1.5 m. Information
from a drillhole indicates t h a t t h e nephrite extends for a t
least 9 m, but t h a t its thickness decreases t o 0.45 m. Using
these figures, a maximum of about 200 tonnes may be
calculated. Fraser described a slab of nephrite a t t h e base of
t h e in situ deposit a s weighing approximately 150 tonnes.
Two other nephritic lenses w e r e intersected in
drillholes, one was 15 cm thick, t h e other about I m but both
were described a s seminephrite. No e s t i m a t e of reserves in
boulder form was made. In view of lack of production since
1969 it may be concluded t h a t some published estimates must
be revised downward. The diagrammatic section through t h e
main lode shown on Figure 15, is derived from a map
accompanying Fraser (1972).
The interesting feature of this deposit is t h e tremolitechlorite alteration zone developed between t h e serpentinite
and the Cache Creek sedimentary rocks. These a r e greenish
grey in contrast t o t h e usual whitish contact reaction zones
o r "whiterock" of most nephrite occurrences. They a r e
mainly tremolite in fibrous form approaching a nephritic
texture in places and it seems possible t h a t some of t h e
material could have been mistakenly included in estimates of
nephrite reserves.
According t o Fraser (1972), t h e Jade
Queen nephrite includes t r u e nephrite of Turner's classification. The t u f t s in t h e nephritic base range from 0.01 t o
0.20 mm in length. In schistose nephrite, aggregates a r e 0.02
t o 0.10 mm wide by 0.10 t o 1.30 mm long and t h e seminephrites may include groups up t o 1.90 mm by 5.40 mm.
A spinel-group mineral, commonly picotite, is always
present and forms crystal up t o 1.3 by 0.90 mm. Rounded and
fractured chromite is also noted in crystals up t o 0.5 mm in
diameter or a s rims on picotite.
According t o Fraser, diopside is present in subhedral
crystals or corroded remnants in some thin sections.
Uvarovite garnet was found in several thin sections, usually
as replacement rims on corroded picotite, but also a s discrete
grains in elongated aggregates parallel t o t h e schistosity.
Chlorite occurs a s aggregates of tiny flakes in irregular
patches generally elongated in t h e direction of schistosity and
comprises up t o 10 per c e n t of t h e rock. Titanite is present
as brownish microlites in almost all thin sections. Minor
amounts of carbonate, talc, pyrite and phlogopite were noted
in some specimens.
Plate 10 shows a photomicrograph of typical nephrite
from this deposit.
Mount Ogden
On Mount Ogden a number of sill-like serpentinite
bodies with associated faults and contact reaction zones
occur in C a c h e Creek Group sediments along the western
slope of t h e mountain. The productive ground is held by two
separate companies, Far North J a d e Limited and Continental
J a d e Limited. The discovery of in situ nephrite a t t h e head
of Lee Creek, a tributary of Odgen Creek, was made by
1.Owen and S. Poryko in 1969.
Production of c u t blocks of nephrite was continued by
New World J a d e until 1974 when t h e assets were acquired by
B.C. Gem (H.K.) Limited. Since 1976 claims have been held
by Continental J a d e Limited.
Following t h e success of Owen and Porayko, boulders
and large blocks of nephrite close t o t h e bedrock source w e r e
found t o t h e northwest of t h e Owen-Porayko deposit. The
ground was staked by 1.Barr for Far North J a d e Limited, and
intermittent production began in 1970, when L. Barr c u t high
quality nephrite into small blocks and flew them out from
Ogden Lake. About t h e same t i m e alluvial boulders were
found on t h e creek immediately e a s t of Ogden Creek. A
large block of claims was staked by Kwan Yin Limited and
preparations were made for large scale production.
Apparently t h e quality and/or quantity did not m e e t
expectations and t h e property i s now in other hands.
Examination of aeromagnetic map 5286G (published by t h e
Geological Survey of Canada in 1970) offers a n explanation
for t h e lack of in situ nephrite. The a r e a is underlain by a
large magnetic low, indicative of Cache Creek Group
sediments lacking significant a r e a s of mafic or ultramafic
rocks. The boulders may have been glacially transported
from t h e B.C. Gem property, or if they a r e derived from in
situ deposits along t h e creek, such deposits must b e very
small.
The initial nephrite discovery on Mount Ogden was
made a t the head of Lee Creek along a contact zone between
serpentinite and Cache Creek metasediments. Most of t h e
production has come from t h e locality covered by mineral
claims Lee No. I, 2, 3 and 4 (PI. I I). On the main showing
initial production was from colluvial blocks detached from
the main lode and nearby loose blocks t h a t were transported
by Pleistocene ice. At increasing distances from t h e lode,
the colluvial blocks were modified by stream action t o form
boulders of various sizes ranging from a few kilograms t o
several tonnes.
The contact reaction zone which may be up t o 30 m
wide, consists of talc, schist, "whiterock" bodies, inclusions of
Cache Creek sedimentary rocks and nephrite lenses
(Fig. 16A).

Appraisal of t h e potential is difficult. Possible reserves
may be from 500 t o 1000 tonnes. Probable reserves from an
exposed lode and some talus blocks may yield about
50 tonnes.
Typical nephrite shows microfibres 0.05 mm long with
an average width of 0.02 mm (PI. 12). Minor chlorite and
picotite can be seen in t h e thin section.
A
- Cross-section
Another company, Far North Jade Limited, has worked
jade claims on Mount Ogden intermittently since 1969. Initial
production c a m e from large slabs and blocks of residual or
talus material obviously close to t h e bedrock source. One
large block, estimated t o weigh 70 tonnes (PI. 13), has been
about 25 per c e n t reduced by diamond sawing. Blocks this
size a r e not conveniently handled by even 36-inch diamond
saw blades, but Mr. L. Barr succeeded in extracting about
20 tonnes, most of which has been removed from t h e
property. The nephrite in t h e remaining block shows patches
of good colour but t h e r e is considerable fracturing which
reduces t h e quality.
throughl'rnain showing$
..

Other slabs and blocks were seen on t h e property and
according to Mr. L. Barr (pers. comm., 1976) in situ deposits
have been found. Estimates of reserves a r e speculative but
a r e as high a s 200 tonnes with probable reserves of perhaps
500. Inspection of t h e sawn faces on t h e 70-tonne blocks
suggests that 50 tonnes could be considered proven.

Nephrite has been found in t h e southern end of t h e
Axelgold Range, along t h e trend of t h e Mount Ogden
occurrences (Fig. 14). The deposit consists of large alluvial
boulders or colluvial blocks. The property has not been seen
by the writer.
The owner, Mr. Frank Plut reported a
production of one tonne of high quality nephrite.
His
estimates of reserves is 200 tonnes. From t h e reported size
of some of t h e blocks it is probable t h a t they a r e very close
t o the bedrock source. The a r e a is underlain by serpentinite,
Cache Creek Group rocks and some granitic intrusives.
Further prospecting c a n be expected t o reveal contact
reaction zones with nephrite occurrences.
Plan of nnew showing1'
Figure 16. Diagrammatic sketches of nephrite
deposits on Mount Ogden.
The nephrite, which may be up t o 3 m thick, is
fractured or faulted into blocks as much a s 70 t o 100 tonnes
in welght. When first examined in 1970, t h e nephrite lens
appeared t o be about 50 m long, 3 m wide and 5 m high giving
a volume of 750 m h r about 2250 tonnes.
Some of t h e
material was not commercial grade, and much of i t was low
grade. However, in places the nephrite was t h e finest quality
found-anywhere in British Columbia. Nephrite of various
grades has been found in place elsewhere on t h e property in
four other apparently small occurrences.
At t h e most
important, "the new showing", 600 m southwest of t h e main
showing, serpentinite is close t o a body of granodiorlte and
may be in contact with it. A t one point along this contact,
nephrite in small lenses lies within an alteration zone within
t h e serpentinlte (Fig. 168). A band of nephrite 0.6 m thick
was intersected in a short horizontal drillhole ten f e e t south
of t h e nephrite outcrop. It appears that a contact reaction
zone has developed in a tectonic inclusion and t h a t t h e later
intrusion of t h e granodiorite has obscured t h e original
relationship.
The granodiorite included in t h e Omineca
intrusives of Cretaceous age is probably not relevant t o t h e
formation of t h e nephrite.
Northern British Columbia; Cassiar Segment
The Cassiar segment (Fig. 17) of t h e nephrite bearing
belt of British Columbia follows t h e southern margin of t h e
Atlin Terrane as defined by Monger (1975). A smaller but
still important branch (in t e r m s of nephrite possibilities)
diverges from t h e main belt north of Cry Lake and continues
in a north-northwest direction into Yukon Territory. All t h e
nephrite deposits in t h e Atlin Terrane occur in the eastern
part of t h e belt. Most a r e in the C r y Lake map-area (104 J).
C r y Lake Map-Area
Nephrite in t h e Cry Lake map-area a r e associated with
fault-bounded ultramafic bodies extending diagonally across
t h e map-area (Fig. 18).
The ultramafics a r e mainly
serpentinized pyroxenite, wehrlite with small bodies of
dunite, pyroxenite? and gabbro. Nephrite occurrences a r e
distributed along t h e whole length of t h e serpentinite belt
with a concentration towards t h e eastern end. The quality of
many of these however is very low, some best described a s
tremolite rock. For this reason Figure I 8 is titled nephritic
rocks in t h e Cry Lake map-area.
