This survey returned no significant EM
anomalies over the two gravity targets. The
highest EM response was 4.4, located in the
NW portion of the survey and associated with
a number of responses of similar magnitude.
This suggests an increase in the conductivity
of the underlying sandstone rather than
Cretaceous infill over a pipe.

642986 8137692 Two discrete gravity anomalies, with a third that
was drilled by Ashton + NAD (2012) probably
because of weak coincident conductive
anomaly. No positive sample sites within the

Portions of the planned grid, overlying the
two gravity anomalies, were undertaken. The
highest reading recorded came from the SW
corner of the northern portion, coinciding
with the location of high readings from
Ashton 100m EM data which lies between
two gravity lows.
The NE portion of the full survey area should
be completed to resolve the high readings
over 643,025E 8,137,743N.
A Cretaceous unit was logged in drill-hole
BH0467 located 50m to south.
MerAn021 100m north of
Tristram
643206 8137162 This target comprised a ground gravity anomaly
which is coincident with a weak EM34-3
conductive target identified in the Ashton 100m
line-spaced data. A loam sample that returned
34 chromites is located close to the Ashton EM
anomaly. As the target area is up-slope from
Tristram pipe, it is unlikely that the chromites
originated from this source.

The EM conductivity over this area is very
low, with the highest response being 2.7 -
substantially lower than the values recorded
over the Tristram pipe. Although subdued,
the EM response over Tristram reached 7.
The MerAn021 survey has not explained the
source of the 34 chromite result.
FALCON elevation contours show that
Tristram pipe is down-slope from chromite
anomaly.
EM grid should be extended to east, and infill
south of the MerAn006 survey
