Esperanza Silver Corporation: Cerro Jumil Preliminary Economic Assessment Very Positive

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 8, 2009) - Esperanza Silver Corp. (EPZ) (TSX VENTURE:EPZ)(PINK SHEETS:ESPZF) is pleased to announce the results of a recently completed Preliminary Economic Assessment (PEA) of its 100%-owned Cerro Jumil project in the State of Morelos, Mexico. The base case pre-tax net present value is US$46.7 million with a five percent discount rate and the internal rate of return is estimated at 19.5% using $800 gold.

The study was completed by Vector Engineering Inc. with Mine Development Associates and Lyntek Inc. providing design and cost estimates for the mine and process areas respectively. The Technical Report can be found on Esperanza's website (www.esperanzasilver.com/cerrojumil_techreport.php).

The preliminary economic assessment is based on gold resources previously reported by the company (News Release Oct. 1, 2008: www.esperanzasilver.com/release.php?R_ID=142). New drilling is planned for the fourth quarter of this year to increase the resource base.

This assessment is preliminary in nature and includes inferred
resources in addition to measured and indicated resources.
Inferred resources are considered too geologically speculative
to have economic considerations applied to them so as to
categorize them as a proven or probable reserve. There is no
certainty that the PEA results will be realized.
--------------------------------------------------------------


The PEA base case envisions the Cerro Jumil project as a conventional open-pit/heap-leach gold operation, using well-proven technology. The base case incorporates the use of company-owned mining equipment for all open-pit mining operations. The process design calls for two-stage crushing of run-of-mine ore to a nominal size of less than two inches. Crushed ore is stacked on leach pads in 6-metre lifts and irrigated with solution to dissolve the gold. The solution is collected and gold is recovered in a series of carbon columns. Precious metals (the ore contains a nominal amount of silver) are then stripped from the carbon and recovered by electrowinning. The resultant sludge is smelted to produce a dore which is shipped offsite for final refining.

Three other development scenarios were also considered as part of the PEA. These include (i) owner mining with no crushing, (ii) contract mining with crushing and (iii) contract mining with no crushing. These alternatives had less favorable outcomes, but will be subject to future evaluation as new metallurgical and cost data is collected.

A further objective of the PEA was to provide detailed recommendations to collect other data necessary for a final feasibility study. A budget of US$4.8 million was recommended for additional drilling, geotechnical investigations, and continued metallurgical test work among other programs. Metallurgical testing is on-going and Esperanza is preparing for a new drilling campaign to start by the fourth quarter of 2009.

Bill Pincus, Esperanza's President, said, "We're extremely pleased that this assessment has yielded such positive results and are anxious to take Cerro Jumil to the next level of its development; currently we have the funding to do so. Shortly we will begin a new drill program which includes substantial in-fill plus exploration drilling. We anticipate converting certain material now characterized as waste into resources. This would have a positive affect on the project's gold production levels, mine life and returns."
