ROCK TECH LITHIUM INC 
By Vancouver, British Columbia, Canada, April 16, 2013 - Rock Tech Lithium Inc. (TSX-Venture: RCK; Frankfurt: RJIA) (the "Company" or "Rock Tech") announces updated assay results for two drill holes at its Lochaber graphite project in Quebec.
The assay results of these drill holes, PB-12-10 and PB-12-11, were originally disclosed in a news release on January 7, 2013. After interpreting the assay results, the Company sent the remaining core intersections not initially submitted to the laboratory.
Highlights from these two drill holes include:
- Drill hole PB-12-10 intersected 56.62 metres of 3.19% graphitic carbon ("Cg"), and
- Drill Hole PB-12-11 intersected 57.58 metres of 2.01% Cg.
The above mentioned drill holes tested the graphite mineralization along electromagnetic conductor 'C'. The electromagnetic conductors were identified during geophysical surveys in September, 2012 (click here to view a map).
"The resampling is proving very effective as it has better defined the extent of the mineralization along electromagnetic conductor 'C'. We look forward to receiving the remaining assay results from the lab over the next few weeks," said Afzaal Pirzada, Rock Tech's Vice President of Exploration and interim CEO.
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.
Drill hole PB-12-10 is located at 474873E, 5055668N (NAD 1983, Zone 18N) with azimuth 101.9
