Endeavour Silver Expands Indicated and Inferred Silver-Gold-Zinc-Lead Resources at the Parral Project in Chihuahua State, Mexico

VANCOUVER, BRITISH COLUMBIA--(Marketwire - March 1, 2011) - Endeavour Silver Corp. (TSX:EDR)(NYSE Amex:EXK)(DBFrankfurt:EJD) released today an NI 43-101 resource estimate for its Parral Project located adjacent to the city of Hidalgo de Parral in Chihuahua State, Mexico. The indicated and inferred resources were expanded significantly as a result of Endeavour's exploration drilling program in 2010.

The Parral Project is situated within the famous silver district of Parral and covers about 1.1 kilometers of strike length along the Esmeralda zinc-lead-silver-gold vein system on the El Cometa (19.6 hectares) and San Juanico (17.1 hectares) properties. A total of 9,954 meters of core drilling were completed in 34 drill holes on the San Juanico properties in 2010 in order to define the expanded resources.

Micon International Ltd. was commissioned in late October 2010 to provide an independent audit of Endeavour's updated resource estimate for the Parral Project. Their report entitled "NI 43-101 Technical Report Audit of the Mineral Resource Estimate for the Parral Project, Chihuahua State, Mexico" dated Dec 15^th 2010, is now available on SEDAR. Their audited mineral resource estimate to October 27, 2010 is as follows:

Summary of Parral Project Resource Estimate as of October 27, 2010 (NSR Cut-off US $40)
Resource Category	Thousand Tonnes	Ag (g/t	)	Au (g/t	)	Cu (%	)	Pb (%	)	Zn (%	)	NSR/Tonne ($US	)
Indicated	1,631.0	49.39		0.90		0.15		2.87		2.86		75.38
Inferred	1,302.9	63.47		0.88		0.20		2.55		2.28		73.77

The Qualified Persons for Micon are William J. Lewis, B.Sc., P.Geo., Charley Murahwi, M.Sc., P.Geo, MAusIMM, Dibya Kanti Mukhopadhyay, MAusIMM. Micon previously audited the Parral resources up to December 31, 2008 in a technical report dated March 15, 2010, also available on SEDAR. Mineral resources that are not mineral reserves do not have demonstrated economic viability. There are currently no mineral reserves estimated for the Parral Project.

Because the Parral Project resources are poly-metallic, each sample interval was assigned a value based on the net smelter return (NSR). Gold and silver prices were based on Endeavour's base case model for 2010 and zinc and lead prices were as of July 2010. Metallurgical recoveries were derived from Endeavour's metallurgical lab test-work to date. The NSR parameters were as follows:

Net Smelter Return (NSR) Cut-off Parameters for Parral Project Resources
Gold Price	US $1,000 per oz
Silver Price	US $16 per oz
Lead Price	US $0.65 per lb
Zinc Price	US $0.65 per lb
Gold Recovery (Overall)	75%
Silver Recovery (Overall)	71%
Lead Recovery (Overall)	80%
Zinc Recovery (Overall)	74%
Smelter Terms	Based on generic contract

Based on current metal prices of $33 per oz silver, $1400 per oz gold, $1.10 per lb lead and $1.10 per lb zinc, the NSR values rise 88% to approximately US$142 per tonne for indicated resources and US$139 per tonne for inferred resources.

Barry Devlin, Vice President of Exploration, commented, "Our 2010 drill program at Parral was successful at extending the previously drilled poly-metallic vein mineralization on the El Cometa property further north onto the San Juanico properties. As a result, the resource tonnes and contained metals in the indicated and inferred resources all rose substantially over the previous estimate."

"Endeavour now plans to commission a preliminary economic analysis of the Parral Project in order to determine how best to develop the project to commercial production. The Parral properties are located only one kilometer from an operating 500 tonne per day, government-owned, custom flotation and cyanidation process plant."

Endeavour plans to release its Fourth Quarter and Year-End 2010 financial results before the market open on Tuesday, March 22, 2010. A conference call to discuss the results will follow at 10:00 AM Pacific Time (1:00 PM Eastern Time) on the same day. Endeavour also plans to release its updated NI 43-101 reserves and resources next week.

Barry Devlin, M.Sc., P.Geo. Vice President, Exploration is the Qualified Person who reviewed this news release and supervised the surface drilling and sampling programs at the Parral Project. A Quality Control sampling program of reference standards, blanks and duplicates has been instituted to monitor the integrity of all assay results. All core samples are split at the Parral, Guanajuato, or Guanacevi field offices and shipped to ALS-Chemex Labs, where they are dried, crushed, split and 50 gram pulp samples are prepared for analysis. Gold and silver are determined by fire assay with an atomic absorption (AA) finish and lead, zinc and copper are determined by AA.
