Rock Tech Identifies Pegmatite and Other Exploration Targets at its Quebec Properties
(via Thenewswire.ca)
Vancouver, British Columbia, Canada, June 22, 2012 - Rock Tech Lithium Inc. (TSX-Venture: RCK; Frankfurt: RJIA; Pink Sheets: RCKTF) (the "Company" or "Rock Tech") is pleased to announce results from airborne geophysical surveys at its Kapiwak and Lacorne lithium properties in Quebec.
Kapiwak Property, James Bay Region (Quebec)
A total of 3,494.6 line-kilometres of a 3-axis helicopter-borne magnetic gradiometer, gamma-ray spectrometry and aeromagnetic geophysical data were acquired from two claim blocks (Kapiwak North and Kapiwak South) in August 2011. The primary aim of the survey was to detect pegmatite zones similar to those identified on Lithium One's deposit located adjacent to the north of the Kapiwak South Block. The observed signature of the Lithium One deposit, along with its characteristic features such as high potassium values, location along a local topographic high and with nondescript magnetics, was used as a model. Two methods were used for targeting, a ternary image and a K-Means clustering statistical method - both methods appear viable and final targets are based on a combination of these methods.
A 2,016 line-kilometre ZTEM survey was also flown on the Kapiwak South Block in August 2011. The interpretation of the ZTEM data was primarily based on delineating strongly conductive trends at various depths, ranging from 100 metres to 800 metres below surface, associated with favourable geology and varying magnetic responses.
The following exploration targets were identified in the surveys:
-A total of twenty-seven (27) pegmatite and two gold exploration targets were identified on the North Block;
-A total of forty-nine (49) pegmatite and one gold exploration target were identified on the South Block along with three (3) similar conductive zones representing favourable geological contacts and varying magnetic responses for lithium exploration.
The gold exploration targets identified on the Kapiwak property are primarily based on historical mineral occurrences, rock chip geochemistry data and favourable lithology
Lacorne Property, Val d'Or Region (Quebec)
A total of 4,001.3 line-kilometres of ZTEM and caesium magnetometer surveys were flown over the Lacorne property in August 2011. The objective of the surveys was to delineate pegmatite exploration targets similar to those identified on Canada Lithium's Quebec Lithium deposit and Glen Eagle Resources' Authier deposit both of which are located in the vicinity of the Lacorne property. Two methods were used for targeting, a K-Means clustering statistical method and the incorporation of areas close to known pegmatite occurrences/deposits and/or close to historical rock chip samples with anomalous lithium values.
The following exploration targets were identified in the surveys:
-Six (6) pegmatite targets based on K-Means classification criteria;
-Six (6) pegmatite targets based on favourable geology and nearness to known lithium occurrences;
-Two (2) gold exploration targets partially located on the Lacorne property which are based on magnetic anomalies and suitable volcanic rocks;
-One (1) nickel exploration target based on geology and magnetic trends; and
-Five (5) major trends associated with moderate to strong linear conductive anomalies.
Gold exploration targets on the property are based on historical mineral occurrences data and favourable lithology. Potential targets for nickel mineralization are based on an extrapolation along the magnetic strike from several known nickel occurrences within similar ultramafic rocks.
Geotech Limited of Ontario ("Geotech") was contracted to carry out the survey. The geophysical survey flight lines were oriented north-south with a nominal spacing of 200 metres with tie lines flown perpendicular to the flight lines at spacing of 2,000 metres. The magnetic and radiometric data was processed by Condor Consulting Inc. of Lakewood, Colorado ("Condor"). The ZTEM survey was impacted by Hydro-Quebec power lines and was processed by Geotech's in-house team of geophysicists by widowing out the power line impacted data. Geotech also used magnetic data to supplement its ZTEM interpretation.
Company President and CEO, Eunho Lee, commented, "The targets identified during the airborne geophysical surveys have provided us with a lead for further ground exploration work on these properties. Further exploration programs will include prospecting, sampling, geological mapping and trenching."
