Southern Hemisphere Mining Limited announced that work will commence on an updated resource estimate for its Llahuin Copper/Gold Project in central Chile in early April as drilling continues to expand and enhance the Llahuin Project. The company has received further excellent diamond drill results extending the higher grade core within the Central Porphyry Zone. A recent review of the results received to date highlights the strategic importance of this higher grade core. It has the potential to provide higher grade feed during the initial stages of production, is easily accessible, close to surface and requires no pre-strip, thereby enhancing the Llahuin Project economics. Recent drilling has also added further weight to the emerging Ferrocarril Zone, which is located approximately 2km south of the Central Porphyry Zone, with results confirming the presence of a dioritic porphyry similar to the Central Porphyry Zone. The majority of drilling to date has been in the Central Porphyry Zone, but further drilling, which is being undertaken by the Llahuin Joint Venture between the company and Lundin Mining Corporation, includes the Ferrocarril Zone and Cerro de Oro Zone; which is located approximately 1km south of the Central Porphyry Zone. Work on a resource update for the Llahuin Project is planned to commence in April following a drill data cut-off at the end of March 2013. The last resource estimate update was based on 33,812m of drilling, following a mid-August 2012 drill data cut-off. The September 2012 resource included a higher grade core Measured Resource of 51Mt at 0.5% Cu Eq being 51Mt at 0.38% Cu; 0.12 Au g/t and 0.007% Mo using an 0.36% Cu Eq cut off. The new May 2013 resource update is expected to include approximately 13,000m of additional drilling, being a 38% increase.
