What are Tuanche Ltd's Business Segments?
COPPER AND GOLD BUSINESS In August 2013, the start-up of operations began at the Mount Milligan Mine with
the first feed to the concentrator, and in September 2013, the first copper-gold
concentrate was produced. Mount Milligan Mine reached commercial production
as of February 18, 2014, defined as operation of the mill at 60% of design capacity
mill throughput for 30 days. At year-end 2015, we achieved and on occasion exceeded
design mill throughput of 60,000 tonnes per day ("tpd"). In 2015,
we utilized a temporary secondary crushing facility to help us achieve design
throughput. As previously disclosed, we have determined that a permanent secondary
crushing circuit will provide more reliable throughput levels for the long-term
at lower cost than what we can achieve with the temporary secondary crushing
circuit. We have made the decision to move forward with the construction of
the permanent secondary crushing circuit which we expect will enable us to consistently
achieve average daily throughput of approximately 62,500 tpd.
MOLYBDENUM BUSINESS
Until the Mount Milligan Mine became operational in the fall of 2013, our business
was primarily focused on the extraction, processing, roasting, and sale of molybdenum.
Through the end of 2014, we operated an open-pit molybdenum mine and concentrator
in Idaho, USA (“TC Mine”), and an open-pit molybdenum mine, and
concentrator in British Columbia, Canada, in which we own a 75% joint venture
interest (“Endako Mine”).
