VANCOUVER, May 3 /CNW/ - NSGold Corporation (TSXV: NSX) is pleased to report that it has received a National
Instrument 43-101 compliant resource estimation for the West Zone of
its wholly owned Mooseland Gold Project in Halifax County, Nova
Scotia. Inferred gold resources are estimated at 210,000 ounces using a 3 gram
per tonne cut-off grade and a minimum width of 1.5 meters. This estimate represents an increase of more than 80% over the April 28,
1988 historic resource estimate prepared by Kopp for Hecla Mining.
These earlier estimates assigned less than 40% of the total gold
resources at Mooseland to the West Zone.
The updated resource estimate was prepared by MineTech International
Limited. of Halifax, N.S. and is based on drill core assay results from
3,613 meters of drilling in 13 holes NSGold completed in 2010; 21,845
meters in 85 diamond drill holes completed by Hecla Mining (Canada)
Ltd. in 1986-1988; and 828 meters in 4 diamond drill holes completed by
Azure Resources Ltd. in 2003. The resource estimates as calculated by
MineTech at varying cut-off grades are included in the following table.
Using a cut-off grade of approximately 1 g/tonne for mineralized zone
interpretation, sixty-one mineralized veins were identified. Using
inverse distance weighting to calculate block grades, it was determined
that eighteen veins contained blocks that exceeded the 3 g/tonne block
cut-off grade that was used to identify mineral resources. Gold
assays of more than 20 g/tonne were reported as a value of 20 g/tonne.
This practice is known as top cutting and minimizes the impact of the
"nugget effect" prevalent in this type of ore. Historic resource
estimates did not account for the nugget effect and reported values as
assayed. Additional inputs for the resource estimation are detailed in
Through diamond drilling, sixty-one mineralized veins have been
identified in the West Zone of the Mooseland gold deposit. The nested,
stratiform veins are steeply dipping over a relatively tightly-folded
anticline, the axis of which is oriented approximately east-west with a
shallow westward plunge. The veins are narrow, most are less than one
meter wide while some veins are up to several meters wide, especially
near the fold's apex or "saddle" where intersections can reach 10
meters or more.
The identified strike length of the West Zone is approximately one
kilometer. The West Zone is "open" at depth and towards the west. A
fault defines the eastern extents of the west zone. This left-hand
fault offsets the deposit, dividing into West and East Zones. The
deposit is "open" at depth and along strike.
NI 43-101 Report
A copy of the 43-101 technical report prepared by MineTech including the
updated gold resource estimates for the West Zone will be filed on
SEDAR within 45 days.
East Zone Results
An analysis of the data on the East Zone is currently underway and a
resource estimate for this area is expected to be completed by mid-June
Future Work at Mooseland
The 2010 program focused on the known ore zones defined by earlier
programs with a view to confirming the historic data and building
confidence in the ore body model. This objective has been met.
Immediate plans for the Mooseland deposit are to continue drilling to
further delineate and expand the mineralized zones with the objective
of converting the inferred resource to measured and indicated
resources. Engineering and environmental work will focus on the
permitting for the re-opening of the West Zone decline to provide
access for future underground drilling and bulk sampling.

Notes for Mooseland West Zone Resource Estimate
Cut-off grade for mineralised zone interpretation was 1 g/tonne.
Block cut-off grade for defining Mineral Resources was 3 g/tonne.
A top-cut grade of 20 g/tonne on composited samples, diluted to the
minimum mining width was used. The top-cut was chosen based on
Gold price was $US 1200 per troy ounce.
Zones extended up to 25 metres down-dip from last intercept. Along
strike, zones extended halfway to the next cross-section.
Minimum width was 1.5 metres. Narrower intercepts were diluted at zero
Planned dilution, to the minimum width, was included. Non-planned
dilution was not included.
