The independent mineral resource estimate for Nuevo Milenio continues to be advanced. Challenges encountered in providing data to the consultant in a timely manner have impacted progress on the mineral resource estimate. Given the large amount of data involved including over 32,000 metres of drilling, a significant volume of surface samples, trench samples, underground channel samples as well as properly identified location coordinates for all but the drilling data combined with reviews and fact checks were significantly more time consuming than anticipated. The Company anticipates the release of the mineral resource by May month end 2012.
