Endeavour Silver Corp. - Parral Mine, Mexico

The Parral Silver District is located some 210 km. (135 mi.) south of Chihuahua City, the capital of the State of Chihuahua, Mexico, and approximately 110 km. (70 mi.) north of Guanacevi, Durango, where Endeavour operates the Guanacevi Mines Project. Silver was first discovered in the Parral Silver District in 1631 and by 1655 more than 60 small mines were operating, principally along the Veta Colorado vein.

Land Package - 32.7 hectares (80.8 acres)

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)	Ag Oz	Au Oz	Cu (%)	Pb (%)	Zn (%)	NSR/Tonne ($US)
Indicated	1,631.0	49.39	0.90	2,590,000	47,200	0.15	2.87	2.86	75.38
Inferred	1,302.9	63.47	0.88	2,659,000	36,900	0.20	2.55	2.28	73.77

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.
