Esperanza Reports 72% Heap-Leach Recovery at Cerro Jumil and Further Positive Drill Results

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Dec. 11, 2007) - Esperanza Silver Corp. (TSX VENTURE:EPZ)(PINK SHEETS:ESPZF) is pleased to update results on its 100%-owned Cerro Jumil gold property in Morelos State, Mexico:

- Heap-leach test results indicate 72% gold recovery on material crushed to nominal 1 inch size

- Drill Hole RCHE-07-49 yielded 75 meters containing 1.05 g/t gold

- Drill Hole RCHE-07-50 yielded 70.5 meters containing 1.34 g/t gold

- Drill Hole RCHE-07-54 yielded 69 meters containing 1.09 g/t gold

Continued Drilling Success - Third Rig Added

Infill and expansion drilling continues on the property where a third drill was added to the program in early December. Two diamond-drill rigs and one reverse-circulation rig are now on site. Drilling is largely concentrated in the eastern mineralized portion of the property called the Southeast Zone. The new results demonstrate good continuity of gold mineralization within this zone. Future drilling will continue to move east and northeast to test its limits.

Results from the most recent drilling are:

72% Heap-Leach Recovery Indicated

SGS Mineral Services' recent report that simulated heap-leach testing of drill-core material from the Southeast zone indicates a recovery of 72% on material crushed to a nominal 1 inch size and 73% for 3/4 inch material. Further studies are proposed in order to optimize these recovery rates.

Two 50 kilogram columns were prepared using the nominal 1 inch and 3/4 inch crush sizes. Fine material (-10 mesh) was agglomerated using lime and cement and added to the columns. Heap-leach solutions percolated through the column for 61 days.

Esperanza will continue studying heap-leach optimization while also examining the economic viability of conventional milling and processing as an option. Previous testing (non heap-leach) yielded recovery rates between 92% and 95% indicating that conventional processing may be an alternative.

2008 Work Program

Bill Pincus, Esperanza's President and CEO, commenting on the results said, "The on-going drill program is yielding excellent results. The drill intercepts can be favorably compared with many of the newer discoveries in Mexico. The new heap-leach test results support our earlier impression that this low cost recovery method is a viable alternative for the development of Cerro Jumil although further study is required to make the best choice."

He added, "During 2008 we will continue drilling to extend the known mineralization as well as to test new targets. We will also optimize the metallurgical test work and begin other engineering studies to move the project toward an initial feasibility study. Our first major feasibility objective is to complete an initial resource estimate in the first half of 2008."
