Battle
Mountain Nevada
In 2006 Sparton acquired the SBD claims
in Lander County near Battle Mountain and the Coal Canyon
claim group in Pershing County , east of the town of Lovelock.
SBD
Claims
The SBD claims comprise 29 lode claims
covering approximately 2 square kilometres within the prolific
Battle Mountain-Eureka Gold Trend. The claims are adjacent
to Newmont's Trenton Canyon open pit mine and approximately
6 km northeast of Newmont's Phoenix Mine development infrastructure.
Glamis' Marigold Mine is located about 5 km to the north.
Drilling in 1992-93 by Echo Bay Mines Ltd identified the
West, Stibnite and South gold zones on the SBD property.
Subsequent drilling up to 1997 indicated several significant
areas where mineralization located by the earlier work
was not adequately followed up. Exploration had concentrated
on testing favourable stratigraphic rock units to locate
drill targets and ignored the structural controls now known
to control much of the mineralization in the Battle Mountain
area.
Mineralization on the SBD claims appears to be controlled
by fault structures along which intrusive rocks have been
emplaced. The final drill program, carried out in 1996-1997,
by International Calneva focussed on the Stibnite and West
zones. Over half of the drill holes were vertical and did
not intersect the near vertical structures hosting gold
mineralization. Several angle holes were also drilled but
had little chance of intersecting mineralization as they
were drilled in a northerly direction sub parallel to the
structural elements being tested. Highlights from the 1996
(15 shallow holes) program on the Stibnite and West Zones
include:

The initial phase of Sparton's SBD exploration
program, completed in late 2006, consisted of over 23 line
kilometres of detailed Controlled Source Audio Magneto
Telluric (CSAMT) and magnetic geophysical surveys to properly
delineate structures and alteration on the claims and correlate
them with the known mineralization. This technique is widely
used in Nevada exploration and has been very successful
in providing reliable structural information.
Four new
significantly conductive areas were outlined in the central
part of the claim area. These appear to represent buried
targets. Previous mapping indicates the presence of rock
alteration including silicification and iron oxide development
in each of these areas. The areas vary in size from 300
metres long by 50 metres wide to about 900 metres long
and over 100 metres wide. None of these areas of interest
have been previously drill tested.
The known gold zones
in the western part of the SBD claim area (Stibnite, West
and South Gold Zones) are all associated with conductivity
trends and structural intersection zones that are incompletely
tested.
The South Gold Zone, where reverse circulation
drilling by Echo Bay Mines Limited intersected 8 m of 1.54
g/t and 33 m of 1.54 g/t gold in drill hole number 19-93
is associated with a conductivity zone nearly 900 metres
long. It is located at the southwest margin of a large
magnetic feature. Gold mineralization intersected in past
drilling is associated with intrusive dykes in the zone.
The intersections in hole 19-93 were never followed up
and several nearby holes in the area were drilled vertically
with little chance of intersecting near vertical structures,
or they were located away from the conductive zone found
in the current program. Several other shallow holes drilled
by Santa Fe Pacific (now Newmont) in this area also intersected
highly anomalous gold values adjacent to intrusive rock
dykes (0.5 to 0.8 g/t gold over 5-20 metre widths), but
were not followed up.
Upon completion of data interpretation,
a drilling program will test newly outlined target areas
and further define the mineralization previously located
in this very prospective land package. A Bureau of Land
Management drilling permit was received in February 2007
and subject to weather conditions and drill availability
work to test the targets is expected to start in Q2 2007.
