Rock Tech Drills 82.70 metres of 2.53% Graphite at Lochaber

Vancouver, British Columbia, Canada, April 29, 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’. A few other conductors and magnetic anomalies were also tested during this drill program. 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-12-24 intersected 18.78 metres graphitic carbon (“Cg”) in two intersections with grades ranging from 1.19% Cg to 3.43% Cg, including 11.86 metres at 2.71% Cg;

- Drill hole PB-12-25 intersected 143.90 metres of Cg in various intersections with grades ranging from 1.32% Cg to 4.41% Cg, including 82.70 metres at 2.53% Cg, and;

- Drill hole PB-12-26 intersected 46.30 metres of Cg at various depths with grades ranging from 1.16% Cg to 2.03% Cg, including 24.00 metres at 2.03% Cg.


“Drill holes PB-12-24 and PB-12-26 were drilled in the vicinity of the historical Plumbago mine area. Both drill holes intersected graphite mineralization indicating potential areas for additional exploration. The results for drill hole PB-12-25 further confirm the extensiveness of the mineralization along electromagnetic conductor ‘C’,” said Afzaal Pirzada, Rock Tech’s Vice President of Exploration and interim CEO.


To date, the Company has received and announced assay results for twenty six drill holes and seven trenches. Assay results for the final nine 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.
