Graphite; Graphene and Fried Chicken!, page-8

Sri Lanka is known to be underlain up to 90% by Proterozoic high grade metamorphic rocks with Proterozoic sediments, particularly along the coastal regions. According to the US Geological Survey Sri Lanka currently produces about 4,000 metric tons od graphite per annum. However, Sri Lanka’s graphite is a rather unique product. The country produces lump and chippy dust graphite and is the world’s only source of these particular materials. Lump and chippy dust graphite are the highest-value graphite products found globally. These unique and comparatively higher margin vein (lump) deposits currently make-up less than 1% of the world graphite production. In 2012, prices for Sri Lankan lump and chip graphite averaged $1,990 per metric tonne, significantly higher than prices reported for other products, such as flake or amorphous graphite.
Production in recent years has been sourced from two graphite mines:
Kahatagaha Graphite Lanka Ltd., owned by the Government of Sri Lanka

• Producing 80 tonnes monthly, and is planning to increase production to 125 tonnes monthly in 2013
• Currently mining at a depth of 350m (1,100 feet)
• Minimum 90% purity with majority by weight being lump type at 95% carbon, +10mm

Kahatagaha Kolongaha is one of the high-value mines accounting for Sri Lanka’s current output of lump and chip graphite. The mine has been in production since 1872 and reportedly produces a product with total graphitic carbon content greater than 90%.
Bogala Graphite Ltd., a 90%-owned subsidiary of Germany’s Graphit Kropfmühl AG (a part of the AMG advanced materials grouping)

• Producing 250 tonnes monthly from one single vein mine
• Being mined from both ends at 2,299 feet from underground
• Was producing 6,000 tonnes of value-added graphite annually prior to the global recession and restarted operation at its Ragedara vein mine in July 2012

The German company entered the Sri Lankan sector in 2000, buying control of the Bogala graphite mine, a historic operation dating back to 1847.
