ORIGO Partners has announced the results of a scoping study on the Mandal Moly molybdenum and tungsten project in northwest Mongolia which is wholly-owned by its portfolio company Moly World. The study has identified the potential for an initial small-scale open pit operation that could be brought into production for an investment of US$43.6 million, including working capital.

Initial annual production from the operation would be 3000 tonnes of molybdenum and 155 tonnes of tungsten concentrate. The study also outlines the option of further expansion dependent upon future molybdenum prices.

The study has estimated that the project, which benefits from world-class grades and a low strip ratio, is capable of returning an IRR of 46.8%, with a net present value of US$80.8 million (at a 12% discount rate) at current molybdenum prices.

The Mandal Moly project is a single exploration licence covering 2360 hectares and is about 40km north of Tsagaan-Uul Soum in Khuvsgul province. Based upon a JORC-compliant resource statement issued in 2012, the project contains 203.4 million tonnes of ore grading 0.1261% molybdenum with total contained molybdenum metal of 256,000 tonnes. The project also benefits from high levels of associated tungsten and is strategically well placed being located close to existing water and power infrastructure.

The study identified an initial mining area with favourable conditions that could be accessed via a small-scale open pit located on a shallow high-grade zone of the deposit with molybdenum grades of 2110ppm and a strip ratio of 0.55:1. In addition, the study defined processing and infrastructure requirements to support average annual production of about 3000 and 155 tonnes of molybdenum and tungsten concentrate respectively.

The initial pit has a 14-year operating life with an average life of mine cash cost of US$21.4 per tonne of ore extracted. Initial total capital for this development is estimated to be US$43.6 million and production could start within two years of construction commencing.

Work on a detailed mining feasibility study will begin shortly and discussions with the government around conversion of the project's licence to a mining licence are under way.

Origo acquired a 20% stake in Moly World, a holding company which owns the Mandal Moly deposit, for US$10 million in 2011. In addition, a subsidiary of Origo has an offtake agreement covering up to 20% of all production from Mandal Moly while Origo holds an interest of between 5 and 20% in Moly World.

Origo's CEO Chris Rynning says, "The results of the study confirm the potential to develop an initial small-scale operation at Mandal Moly with high rates of return and low initial capital investment. This approach minimizes risks whilst giving us the option to significantly expand production at a later date."
