NSGold Corporation Reports an 80% increase in the gold resource at the West Zone of the. Mooseland Gold Project
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.
Cut-off Grade Tonnes Above Average Diluted Inferred Ounces
(g/tonne) Cut-off Grade (g/tonne) (ozs)
4.0 930,000 5.2 160,000
3.0 1,400,000 4.6 210,000
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 Appendix A.
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.

Appendix A
Notes for Mooseland West Zone Resource Estimate
- Cut-off grade for mineralised zone interpretation was 1 g/tonne.
- lock 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 statistical interpretation.
- 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 grade.
- Planned dilution, to the minimum width, was included. Non-planned dilution was not included.
