TORONTO, ONTARIO -
Stingaree Valley
Gravity and induced polarization (IP) surveys were conducted
earlier this year at the Stingaree Valley project located in
Churchill County, Nevada by Zonge Geosciences of Reno, NV. The
property is located in a valley floor between the historic Chalk
Mountain and Westgate mining districts. The surveys were designed
to test for possible copper/gold porphyry mineralization and
structurally or stratigraphically controlled gold mineralization.
The data interpretation has now been completed by Zonge.
The gravity survey indicated a broad high that extends 1.5 to 2
kilometers to the southeast of Chalk Mountain and is interpreted to
be an area of relatively shallow (100 to 150 m) pre-Tertiary rock
lying beneath alluvial cover.
The IP/resistivity survey detected a zone of highly anomalous IP
response that defined a northerly trending zone that crosses the
area of shallow pre-Tertiary rock. The IP anomaly is associated
with a gravity gradient and a strong lateral resistivity contrast
that suggests a significant structural feature along the western
side of the IP anomaly. The anomaly is open to both the north and
south and extends to the east at greater depth. While such
high-amplitude anomalies can be caused by graphitic carbon, the
existence of a coincident reported historical spontaneous potential
anomaly makes this a priority target.
In the case that the anomalous IP response is related to
graphitic carbon, the source could be a carbonaceous stratigraphic
or structural unit, in which the carbon has been thermally matured
to graphite in a metamorphic aureole surrounding an intrusive body.
If the carbonaceous unit is a calcareous shale or shaley limestone,
the anomaly may define a potential host rock. The north-south
trending structure and possible structural block, as indicated by
the gravity high, present a potential target with respect to
structurally and/or lithologically-controlled gold
mineralization.
The primary exploration target defined by this work is the
highly- anomalous, northerly-trending IP anomaly located along the
eastern side of Chalk Mountain. Testing of this feature is planned
by drilling to the west with several fences of holes. In addition,
numerous structural features were indicated in the gravity data and
are also exploration targets. In total, ten to twelve potential
drill targets have been identified.
Sentinel
The Sentinel property is located in northern Humbolt County,
Nevada, approximately 80 miles northwest of Winnemucca.
Australian Ores and Minerals (AOM) discovered gold
mineralization at Sentinel in the 1990's. A portion of their work
comprised a close spaced soil geochemical sampling program.
Approximately 984 soil samples on 100 foot grid spacing were
collected and analyzed over an area of sericite-quartz alteration.
The AOM soil samples reported gold values up to 2.1 ppm with large
areas of plus 100 ppb.
A soil sampling program by Inter-Rock is underway at the
Sentinel property. A total of 230 samples were gathered on a 100
foot grid at both the northern section of the property and at the
southern boundary of the previously outlined anomalous gold zone.
The sampling targeted the hydrothermal clay alteration zones. The
samples have been split and will be submitted for analysis
shortly.
In addition to Stingaree Valley and Sentinel, Inter-Rock holds
three other mineral properties in northern Nevada. Two are
available for option and one has been optioned to General Copper,
Inc.
