The Company continued to address the issues required to lift the performance of Mowana to the next level. Amec Minproc, an international engineering firm, is undertaking the engineering design study on the Secondary and Tertiary ("SnT") crushing circuit to enable it to operate at capacity year round. While this work has been in progress, the SnT has performed well as the feedstock is currently dry. Management has also budgeted for the addition of a washing plant to screen and wash out the fine fraction from the ore before it enters the primary crusher ore stockpile, in order to more permanently alleviate demands on the SnT. Since lead times on delivery of the washing plant and certain SnT components will not allow for installation prior to this year's rainy season, the installation has been delayed for completion until November 2011 (prior to the next rainy season) to conserve capital. The combination of the existing SnT and mobile crushing capacity that was secured earlier in the year should alleviate SnT capacity restrictions that were experienced during last year's rainy season. In an effort to further conserve capital, a dense media separation plant, originally planned for installation in the first half of 2011, has also been put on hold.(info from 31aug 2010 No improvement on equip. till Nov2011)
