MRL Corporation has signed a contract for the supply of drilling services in three locations across the Warakapola graphite exploration area. The contract has been signed with the Geological Survey and Mines Bureau (GSMB).
GSMB will provide all drilling services for a three-hole NQ Triple Tube diamond drilling program to test the vein graphite potential in three locations across the Warakapola Pandeniya/Bopitiya area.
The drill is expected to mobilize to site on or around May 29. The first drill location is at Pandeniya and is expected to be between 50 to 125 metres in depth. The second and third drill holes will be up to 300 metres deep and test the continuity of vein graphite mineralization below the historical shafts and adits.
The contract stipulates a time to complete the drilling program of 15 weeks however MRL will work with GSMB to complete the program in the most efficient manner.
Last week MRL also provided an update on further analytical testing at Nagrom carried out on remnant graphite samples from its Sri Lanka graphite licence EL228.
The results achieved are very promising given this is the first round of testing and is without any process optimization. With a single stag flotation and without any regrind a combined concentrate grade of about 95.4% total graphite as carbon (TGC) and 96.2% TC was recorded. A head analysis grade of 85.6% TGC was achieved which is consistent with the results reported by MRL on March 26.
Many historical workings, including shafts and adits, occur in the licence area, along with remnant graphite stockpile dating back in excess of 50 years. Samples tested by Nagrom were from stockpiles on EL228.
Future drill core samples from the drilling program across the Warakapola area will be tested by Nagrom to establish the in situ grade of any vein graphite intersections encountered.
