Manas Resources (ASX: MSR) has provided an update to the market on the Definitive Feasibility Study progress at the wholly owned Shambesai gold project in the Kyrgyz Republic, Central Asia.
The study has already been completed by the Manas technical team in association with a number of external consultants, and has since been the subject of review by independent technical consultants Snowden Group United Kingdom.
Importantly - the study has now been expanded to include in-pit sulphide material, which the company expects will provide a boost to the economics.
This additional sulphide material overlies the oxide reserves in the optimised pit shell as part of the mine production evaluated in the cash flow model.
The Indicated Resource for this in-pit sulphide material stands at 844,000 tonnes at 2.8g/t gold for 75,000 ounces.
Why this is so important for the study is that recent metallurgical test work has shown that more than 50% of this sulphide material as-mined is readily amenable to the vat leach and heap leach process proposed for the project with recoveries averaging 80% in testwork.
DFS to be reported late March 2012
Manas said in the update that due to the changes in the open pit design and impacts on the plant design from sulphide treatment the final Definitive Feasibility Study findings will now be reported in late March 2012.
All results to date confirm Shambesai as a technically simple, low cost and high margin gold leach project that can be commissioned in less than 18 months, for a very low relative capital cost to its peers.
