INTRODUCTION
A scintillometer survey was conducted on July 31, 1976 on Noranda's Paw Creek 1-76 property. The survey was initiated to
outline the extent of uraniferous occurrences known to exist on
the property. The author was assisted by G. Heavysege; senior
geological assistant, B. Jose and M.J. Murray, junior geological assistants.
A grid was flagged and chained over the surveyed portion of the property at the time of the survey. Four contiguous, unpat- ented mining claims were surveyed these being:
KRL 445933
KRL 445934
KRL 445935
KRL 445936
L OCA TI ON AND ACC Bj3S
Paw Lake is centered at 52 O 45'N latitude and 94 O 00"W longitude, 208km north of Red Lake, Ontario. Float or ski equipped aircraft is the most practical means of reaching the lake but a navigable water route does exist between Deer Lake via the Severn River and a river flowing south out of Paw Lake.
The property lies 1,6km east of Paw Lake and can be reached by a creek 0.5km to the north.
Reconnaissance traverses carried out during July, 1976 as a result of a Kenting radiometric airborne survey in 1975 resulted in the staking of four claims. A ground scintillometer survey was conducted after the staking. Trenching operations followed and 11 additional claims were staked enlarging the property to 15 contiguous claims.
No other work by any company is known in this area.
GENERAL
All rock on and surrounding the property is granitic in com
position. The area is part of the Berens River subprovince of
the Canadian Shield and is Archean in age.
Pink granite aplite banded with white granite pegmatite are
the main targets for exploration. High scintillometer readings
and heavy uranophane stain are associated with these phases.
These two phases are distinctly banded at 110 along which most
of the uranium mineralization occurs.
White to grey weathering granodiorite-trondhjenite comprises
the bulk of the rock and is non-radioactive. Minor phases within
this rock type include xenolithic granodiorite and hybrid
equivalents.
It appears that the uranium mineralization and granite fol
low a subsidiary break sub-parallel to the Bearhead Break and
may be related to a separate and distinct intrusive phase.
S C IN T l LLOMETE R J5 U RVETY
METHOD
Exploranium scintillometer model GRS-101 were used for the
survey. All readings were taken at a height of 1m above the ground
surface and notations were made at each station on the type of
terrain present (i.e. swamp, outcrop or overburden).
.Chained and flagged lines trending north-south were established
for the purposes of the survey. A total of 5.33km of line was
surveyed with 203 readings taken.
For the purposes of this survey any reading greater than
100 cps is considered to be significant.
RESULTS
A large zone of continuous radioactivity was mapped from
LOO, 270S to L740E, 660S at a trend of 115O . Intensities of
200cps are common along with heavy uranophane staining in this
anomalous zone.
The zone is continuous and extends off the surveyed farea both
to the east and west. The zone is on strike with the Paw Lake 1-75
although the latter is approximately 7km to the north
west.
RK COMMENDATIONS AND CONCLUSIONS
The radioactive zone outlined by the survey has been trenched
with good results. In order to test this zone at depth a diamond
drill hole on L120E, BOOS at an azimuth of 180O , dip 45O to a
depth of 500 feet is recommended. Further work should be
contingent on the results of the drill hole.

GEOPHYSICAL REPORT
S CIN TILLOMETER SURVEY PAW CREEK 1-76
INTRODUC^ON
A scintillometer survey was conducted on a flagged grid during the period July 1st to July 10th, 1977. The survey was initiated to outline the extensions of uraniferous occurrences known to exist on four adjoining claims held by the company. The author was assisted by D. McNeil, junior geological assistant.
Eleven unpatented mining claims, contiguous with the original four claims were surveyed. These surveyed claims were:
To the west of the original claims:
KRL.457698 KRL.457702
KRL.457699 KRL.457703
KRL.457700 KRL.457704
KRL.457701 KRL.457705
and to the east of the original four claims:KRL.457695
KRL.457696
KRL.457697
These claims were recorded August 24, 1976.
The following report is supplementary to a report by B. Berger (Paw Creek 1-76) .
LOCATION
Paw Lake is centered at 52Q45'N latitude and 94O00'W longitude, 208 km. north of Red Lake, Ontario. Float or ski-equipped aircraft is the most practical means of reaching the lake, but a canoe route exists from Deer Lake via the Severn River and a river flowing south out of Paw Lake. The north west corner of the property lies 70 meters south of the southeast shore of Paw Lake and the northern boundary extends eastwards for 3.6 km. The eastern claims are reached via a creek flowing to the north of the claim group. This creek bisects the most easterly claim.
PRE VIOUS^ WO RK
Reconnaissance traverses carried out during July, 1976
result of Renting radiometric airborne survey done in 1975,
showed the presence of uranium staining and, as a result four
claims were staked. A ground scintillometer survey was conducted
after the staking, and trenching operations followed. Eleven
additional claims were staked in early August of 1976, enlarging
the property to fifteen contiguous claims.
No work by any other company is known in this immediate area.
All bedrock on and surrounding the property is granitic in
composition. The area is part of the Berens River subprovince
of the Canadian Shield and the rocks are Archean in age.
Pink granite aplite associated with white granitic pegmatite,
are the main targets of exploration. High scintillometer readings
are associated with these phases and the heavy uranophane staining
appears to be restricted to the aplitic granites. These phases are
distinctly banded at 110O in the west and 90O in the east. Dip is
unknown .
White to grey weathering granite comprises the bulk of the
outcrop and was found to be non-radioactive. Minor phases within
this rock type include xenolithic granodiorite and hybrid equivalents,
The uranium mineralization and granite may according to Berger
(1976) , follow a subsidiary break which lies sub-parallel to the
Bearhead Break and may be related to a separate and distinct
intrusive phase.
SC IN T I LLOMETER SURVEY
Exploranium scintillometer model GRS-101 was used for the
survey. All readings were taken at a height of one meter above the
ground surface and notes were made of the type of terrain present
at each station, (ie. swamp, outcrop, overburden)
Chained and flagged lines trending north-south were established
for the purpose of the survey. The lines were spaced at 120 meters
apart, and stations were marked at 30 meter intervals. A total of
15.2 km. of line was surveyed with 526 scintillometer readings taken.
Two test lines were run over the original four claim group as a check
instrument operation and background readings and to tie the two
surveys together.
RESULTS
The west eight claims had two main zones of anomalous
radioactivity. The largest extends from line 240E at 780N to
line 600E at GOON. Readings of 140 cps. were common and readings
as high as 170 cps. were recorded.
In the east three claims, no anomalous readings were found,
however three small areas of uranophane staining were located on
outcrop. The individual zones strike at 90O and are en echelon
at a direction of 65 .
Reconnaissance traverses off the property located uranophane
staining close to the south property boundary. However, in general,
intensity of readings decreased away from the property. A traverse
to the east south-east indicated no uranium staining or radiometric
anomalies.
RECOMMENDATIONS AND CONCLUSIONS
The anomalous areas in the west eight claims are significant.
Anomalous scintillometer readings in conjunction with uranophane
staining, warrant further examination of the area. Two diamond
drill holes are recommended as follows:
1) Line 960 20S Azimuth Oo dip 45O depth 125m.
2) Line 600 660N Azimuth 180O dip 45O depth 170m.
It is also recommended that an additional nine claims be
staked to the south of the property to cover significant uranophane
staining.
Further work on the property should be contingent on the results
of the two drill holes.
