Vancouver, British Columbia, Canada, February 25, 2013 - Rock Tech Lithium Inc. (TSX-V: RCK; Frankfurt: RJIA) (the "Company" or "Rock Tech") announces additional assay results from the drill program it announced on December 10, 2012. This planned 4,600 metre drill program included both step-out and in-fill drill holes and focused primarily on electromagnetic conductors "A" and "C". The electromagnetic conductors were identified on the Plumbago area of the property during geophysical surveys in September, 2012 (click here to view a map).
Highlights of these assay results include:
-Drill hole PB-12-16 intersected 108.36 metres of graphitic carbon ("Cg") at various depths with grades ranging from 1.60% Cg to 12.78% Cg, including 67.95 metres at 2.18% Cg, 13.08 metres at 2.84% Cg, 23.72 metres at 2.78% Cg and 3.61 metres at 1.60% Cg, and;
-Drill Hole PB-12-17 intersected 45.54 metres of Cg in two intersections with grades ranging from 2.56% Cg to 3.58% Cg, including 44.34 metres at 2.56% Cg and 1.20 metres at 3.58% Cg.
Interest in the graphite potential of the Buckingham region of Quebec has increased markedly as of late with several companies staking claims in close proximity to Rock Tech's property and/or announcing exploration plans.
"The results from our trenching and drilling programs confirm the presence of extensive graphite mineralization on the property. Visual inspections of the drill core collected from drill holes along electromagnetic conductor 'A' suggest this graphite zone extends for over 800 metres while remaining open to the north, south and at depth. Similarly, visual inspections of the drill core collected from drill holes along electromagnetic conductor 'C' suggest this graphite zone extends for over 600 metres while remaining open to the north, south and at depth," said Afzaal Pirzada, Rock Tech's Vice President of Exploration and interim CEO.
The Company's geophysical surveys and drill programs have focused exclusively on the Plumbago area of the property which includes only four of the thirty-two claims subject to the property option agreement. The maiden NI 43-101 resource estimate will be based solely on this area. Surface samples taken from the Kelly, McLaren and Burke areas of the property returned graphite results up to 22%.
To date, the Company has received and announced assay results for seventeen drill holes and seven trenches. Assay results for the final eighteen drill holes completed during the fourth quarter of 2012 are pending.
Quality Assurance/Quality Control
All core samples are logged and split by wet diamond saw with half sent to the lab for analysis and half stored securely on site. The core sample lengths typically average 1 metre but vary depending on geological boundaries. Additional QA/QC procedures include inserting blanks and standards into the core sample stream at industry standard intervals with duplicate core samples taken at intervals of twenty. Core samples are prepped and analyzed by Global Mineral Research Limited in Burnaby, British Columbia. During analysis, the core samples are dried, pulverized, leached and roasted at 450? Celsius and 1200? Celsius with measured weights taken between double ignitions. The laboratories also conduct duplicate and internal standard samples at intervals of ten as part of their QA/QC program.
