"Next Steps
The 2015 year end resource/reserve statement for the Tucano project will be released shortly. Following this, the Company will complete a revised life of mine plan for Tucano, based on optimisations that are aimed at maximising cashflow and profit rather than gold production and throughput. The results of these optimisations will shape the open pit mine plan going forward at Tucano, which in turn, will drive the timing of the next steps in scheduling potential Urucum UG development."
