Wolf Minerals Limited (ASX:WLF,AIM:WLFE) is an emerging tungsten producer focused on the redevelopment of the Hemerdon Ball tungsten and tin mine located in Devon, England. The property currently hosts a JORC resource of 401Mt @0.13%WO3 and 0.02% Sn including 117Mt of measured and indicated resource, making it the world’s third largest known tungsten deposit as described by the British Geological Survey.
The Company is developing the Hemerdon project into a low cost, large scale open pit mining operation – first production is expected in 2015. Wolf Minerals is managed by an experienced team of British and Australian mining professionals with an excellent track-record of development and operational success.

Hemerdon Tungsten Project, Devon, England
The Hemerdon Tungsten Project is located approximately 10 km north east of Plymouth, in Devon, England. The project site has access to existing infrastructure and is located near existing open pit clay mining operations. Wolf Minerals acquired the property in 2007 with a pre-existing planning permission valid until 2021.
An extensive tungsten and tin deposit was first discovered at Hemerdon in the 1860’s. The mineralization is characterized by sheeted greisen veining and stock works containing wolframite and cassiterite. The vein system is hosted within a dyke like granite body. The mineralization starts from the surface and is contained within the steeply dipping granite body flanked by metamorphosed sediments. Hemerdon was first developed in 1914 when the need for the metal in weaponry during World War I drove tungsten demand much higher. Commercial production continued sporadically until the mine’s closure in 1945. The total production from Hemerdon during the war period was limited and represents about 1 month’s production from the new operation.
Between 1977-1981, the project owner, AMAX, undertook a significant exploration program within the project area, completing 532 drill holes for 25,400m. The company also completed a comprehensive feasibility study and secured the current planning permission which is valid until 2021. AMAX left the project due to falling tungsten prices.
In 2007, Wolf acquired the project via an option agreement for a 40 year lease, and began validating the historical drill data and updating the feasibility study. An infill drill program was also carried out, upgrading the resource to the JORC standard showing an estimated 401Mt @0.13%WO3 and 0.02% Sn with 117Mt in the Measured and Indicated categories. In May 2011, the Company completed a Definitive Feasibility Study (DFS) on the project, the results of which indicated robust economics based on a 3Mtpa operation over a 9.25 year life of mine. Production is estimated at approximately 350,000 mtu per annum of a wolframite tungsten concentrate with a grade of 65% WO3.
The total funds required to advance Hemerdon into production are estimated at £130 m. In November of 2012, Wolf secured £75 m though a senior debt facility and in March 2014 raised £99m in equity, to complete the funding package for the project.
In December 2013, the Company was granted its Waste Facility Environmental Permit, a key milestone in the environmental permitting process for its Hemerdon tungsten and tin project. The Waste Facility Environmental Permit is the final major permit required in the development of the project.
In February 2014 the 40 year lease for the project was finalised with the landowners and construction at the project commenced. An official “ground-breaking” ceremony, attended by many local stakeholders, was held in March 2014 to commemorate the start of construction activities.
In March 2015, Wolf announced a 34% increase in ore reserves: 35.7Mt at 0.18% WO3 and 0.03% Sn (reported above a 0.05% W (0.063% WO3) cut-off). This was a result of a successful geotechnical drilling program in 2014 which targeted the potential for steeper pit walls. The program resulted in a new pit design which is 65 meters deeper, and an increase in ore reserves.
Wolf Minerals Limited is on the fast-track toward becoming the world’s next tungsten producer. The Company’s main focus is the redevelopment of the Hemerdon Ball tungsten mine located in Devon, England—the world’s third largest known tungsten deposit. Wolf Minerals is managed by an experienced team of British and Australian mining professionals.
Wolf Minerals plans to develop the Hemerdon project into a low cost, large scale open pit mining operation. A completed Definitive Feasibility Study confirms robust project economics including low operating production C1 cash costs forecast at just US$109/mtu.
