Rock Tech Drills 89.50 metres of 2.96% Graphite at Lochaber

Vancouver, British Columbia, Canada, May 15, 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-12-27A intersected 29.11 metres of graphitic carbon ("Cg") in four intersections with grades ranging from 2.07% Cg to 4.84% Cg, including 9.35 metres at 4.84% Cg, and 9.34 metres at 3.37% Cg;

- Drill hole PB-12-32 intersected 16.70 metres at 2.62 % Cg;

- Drill Hole PB-12-33 intersected 31 metres at 1.34% Cg; and,

- Drill hole PB-12-34 intersected 148.05 metres Cg in two intersections with grades ranging from 1.16% Cg to 10.92% Cg, including 89.50 metres at 2.96% Cg;


"These assay results demonstrate the continuation of the graphite mineralization to the north along electromagnetic conductor 'A'. Subsequent drill programs will test the northern extension of this conductor as the mineralization remains open along strike and at depth," said Afzaal Pirzada, Rock Tech's Vice President of Exploration and interim CEO.

To date, the Company has received and announced assay results for thirty drill holes and seven trenches. Assay results for the final five 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.
