A total of 15,433 tonnes were processed for the quarter ended February 28, 2010. During the quarter head grades averaged 1.17 g/t gold and 294 g/t silver. Recovery rates for gold were 83.5 percent, and 62 percent for silver.

At current prices for both metals, a total of 1,873 ounces of gold equivalent were produced, a 0.54 percent increase over the previous quarter's production. Silver grades were in line with expectations and projections however gold grades were below expectations. The gold grade achieved in the last quarter was 1.17 g/t gold whereas projection was for 1.94 g/t gold.

During the month of March 2010, 6,135 tonnes were milled with an average grade of 1.68 g/t gold and 241 g/t silver. Subsequent to quarter end recoveries of gold and silver showed additional improvements. Silver recoveries were approximately 70% for the month of March 2010 and 76% through April 26, 2010. Gold recoveries were approximately 90% for the month of March through April 26, 2010.

Mine Operations and Development

Mine production in Q3 was focused at the Tajos Cuates Mine. The Company mined 13,071 tonnes sourced from several different levels. The average grade of the material delivered to the mill was 1.75 g/t of gold and 391.37 g/t of silver.

Development projects at Macedo and Florida 1240 were restarted during the reported quarter, resulting in 61% of total development in the quarter allocated to exploration and mine infrastructure projects.

Exploration and development work at Macedo during the reported quarter generated positive results. During the period, a new mineralized body was identified for possible future development with estimated grades averaging 3.16 g/t gold and 108 g/t silver over a 1.43 metre width.

**Note that these assay results are from the Company's in-house assay lab and while management is confident of the lab procedures, the data is subject to on-going third party checks and verification. The Company is in the process of up-grading the mine laboratory based on recommendations made in a report by SGS in January 2010.

Drift development in Q3 increased 9.98% over the previous quarter. Of the total drift development during the quarter, 61% was allocated to exploration and infrastructure projects, showing an increase of 14% over the previous quarter.

During the reported quarter, 5.4 km of access roads to drilling locations and 12 drilling platforms were constructed.

Exploration and Development

As at February 28, 2010, 436 metres of drilling had been completed. Two drill holes, FNW-01 and FNW-02, have been completed and two more are in progress. It is planned to use a total of three rigs for the surface drilling and one for underground drilling. Assay results are pending and will be released once received, verified and evaluated.

The drill program at Florida NW area will drill test 13 veins identified on surface up to 1.5 kilometres in length to the northwest of the intrusive at the Florida Mine. These veins are oriented parallel to the Florida Mine and previous surface work supports continuity of the vein system to the northwest of the post-mineral intrusive.

Concurrently, the development of a crosscut at Florida NW which is now underway. The crosscut of 300m is at the 1240 elevation and will cut the continuity of the mineralized zones of the Florida I, II and III, northwest from the intrusive. The crosscut will provide underground access to the 13 veins identified at surface. This is part of the overall mine infrastructure plan of developing over 2.5km in three areas; Crosscut – Florida NW, Footwall drift at level 1240, and the San Eduardo Tunnel.

Mr. Alfredo Parra, a QP as defined under NI 43-101 has reviewed and approved the technical disclosure herein.
