Nevsun Resources Ltd.: Assay Results From Infill Drilling at the Harena VMS Deposit, Eritrea
VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 04/11/11 -- Nevsun Resources Ltd. (TSX: NSU)(NYSE Amex: NSU) is pleased to report the base metal assays from the thirty-four infill diamond drill holes at the Harena deposit within its Bisha exploration license in Eritrea. Nevsun plans to use the infill drilling results to complete a resource estimate, mine plan and mining license application to process the Harena material at its Bisha processing plant. Harena lies 9.5 km southwest of the Bisha Main deposit on an exploration license contiguous to the Bisha Mining license.
Highlights
-- Third VMS near surface discovery on Bisha licenses
-- Oxide gold cap near surface (assays announced on March 2, 2011)
-- Copper and zinc primary sulphide also near surface
-- Likely additional feed for Bisha both in gold and base metals phases
If a mining license is granted, Harena would likely be mined as an open pit. Material would be trucked 9.5 km to the Bisha site for stockpiling and blending with Bisha main feed. The oxide gold cap would be processed in 2012/2013 and the primary sulphide greater than 2016.
Select High Grade Results Include:
-- Hole #H-077 - 12m at 5.62% Cu, from 67.5 meters to 79.5 meters
-- Hole #H-076 - 6m at 3.90% Cu, from 67.5 meters to 73.5 meters
-- Hole #H-054 - 27m at 7.37% Zn, from 70.5 meters to 97.5 meters
-- Hole #H-061 - 7.5m at 7.26% Zn, from 84.9 meters to 92.4 meters
The drilling took place in the fall, 2010 and drill hole locations were selected to infill drill the gossanous oxide cap on 25m x 25m and 12.5m x 25m fences which is the same spacing used to define measured and indicated resource categories at the Bisha Main deposit. The results were positive, and have provided increased confidence to the widths and grades of the volcanic massive sulphide deposit at Harena. A resource estimate on the deposit has been initiated with results expected in late May. If the results are positive a reserve estimate and mine study will be done to support a mining license application.
Detailed results for the sulphide zones are in the attached schedule together with a map of the hole locations. Gold assays for the oxide zone were announced in the March 02, 2011 news release.
Nevsun views the Harena deposit as a potential source of supplemental feed for the processing plant at Bisha. Supplemental feed can provide valuable cash flow as an extension to mine life without having to absorb start-up capital costs.
Darin Wasylik, Senior Geologist for Nevsun, a qualified person under National Instrument 43-101, supervised and directed all work associated with the drilling program.
Sample preparation and analysis were conducted at ALS Chemex of Romania and Vancouver, Canada.

Note. True thickness is estimated at approximately 90% of the drill
intervals reported in the table. All holes were done at 45 degrees
from horizontal.
Historic holes 1 through 27 were carried out and published in 2005 and holes 28 through 44 were carried out in the fall of 2009 and the results were published in February 2010.
