Esperanza Updates Cerro Jumil Project

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 11, 2007) - Esperanza Silver Corporation (TSX VENTURE:EPZ)(PINK SHEETS:ESPZF) is pleased to present the following update of activities at its 100% owned Cerro Jumil gold project in Morelos, Mexico. Results from 25 new reverse circulation drill holes have been received. Highlights include:

- Drill hole RCHE-18 with 25.5 meters (84 feet) containing 1.30 grams Au per tonne (0.04 ounces Au per ton).

- Drill hole RCHE-20A with 33.0 meters (108 feet) containing 1.38 grams Au per tonne (0.04 ounces Au per ton).

- Drill hole RCHE-22 with 30.0 meters (98 feet) containing 1.94 grams Au per tonne (0.06 ounces Au per ton).

The bulk of the new drilling has been in the central portion of the "Southeast zone" and demonstrates the continuity of gold mineralization within this zone. Future drilling will continue to seek extensions of the mineralization northeast of this central zone into an area indicated as prospective by both geologic mapping and geophysical surveys. Additional drilling is also planned to extend the mineralization in the "West zone" further northward. The accompanying map shows the areas of drill-tested gold mineralization as well as those areas which will be drilled in the coming months. The table below provides the drill most recent drill results. To view the map accompanying this press release please click on the following link: http://www.ccnmatthews.com/docs/EsperanzaMap.pdf.

Currently a total of 15,674 meters (51,423 feet) of drilling have now been completed on the project. Two rigs (one core and one reverse circulation) continue to work.

New Targets Identified

An on-going program of district scale reconnaissance has now identified additional drill targets within the 3066 hectare claim group. An additional six targets have been identified and will be investigated by mapping, sampling and possible drilling.

Metallurgical Testing Continues

The previously announced program of metallurgical testing (News Release July 18, 2007) is now well advanced and results are expected in the final quarter of this year. The program, being undertaken by SGS - Lakefield Research, is intended to test the amenability of Cerro Jumil for heap-leach gold recovery. Earlier but preliminary test work had indicated excellent gold recoveries (up to 96% in "bottle-roll" tests). Results from these tests and the on-going drilling will allow Esperanza to begin scoping studies in the near-term(1).
