Updated Tres Perlas Mineral Resource

The new Tres Perlas deposit mineral resource contains 1,332,000 ounces of gold in the Indicated category and a further

1,126,000 ounces of gold are contained in the Inferred category as shown in Table 2 which contains a summary of the updated and increased mineral resources for the CMD Gold Mine.

Mineral Resource Discussion

The latest mineral resource estimate incorporates drilling results received during March post the previous mineral resource estimate in late February 2012. The increase of 153,000 ounces of contained gold over the course of one month is very encouraging.

Figure 2 illustrates the Tres Perlas area, including Natalia and El Sauce. There remains significant potential both adjacent to the Tres Perlas pit and further north around the El Sauce area where recent drilling has discovered significant near surface mineralisation beneath the El Sauce waste dump. Drilling is ongoing with three drills with the mineralisation around El Sauce

open in all directions.
