) said late Friday that it has identified multiple pegmatite and gold exploration targets at its Kapiwak and Lacorne lithium properties in Quebec.
The company said that a total of 3,494.6 line-kilometres of a three-axis, helicopter-borne magnetic gradiometer, gamma-ray spectrometry and aeromagnetic geophysical data were acquired from the Kapiwak North and Kapiwak South claim blocks in August 2011.
Rock Tech noted that a total of 27 pegmatite and two gold exploration targets were identified on the North Block and a total of 49 pegmatite and one gold exploration target were identified on the South Block, along with three 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.
A total of 4,001.3 line-kilometres of ZTEM and caesium magnetometer surveys were also flown over the Lacorne property in August 2011.
The company said the surveys identified six pegmatite targets based on K-Means classification criteria and six pegmatite targets based on favourable geology and nearness to known lithium occurrences.
The Lacorne survey also revealed two gold exploration targets partially located on the Lacorne property that are based on magnetic anomalies and suitable volcanic rocks.
Additionally, one nickel exploration target based on geology and magnetic trends was identified as well as five major trends associated with moderate to strong linear conductive anomalies.
"The targets identified during the airborne geophysical surveys have provided us with a lead for further ground exploration work on these properties," said Rock Tech president and CEO Eunho Lee.
"Further exploration programs will include prospecting, sampling, geological mapping and trenching."
Rock Tech said that gold exploration targets on the Lacorne 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.
Rock Tech said the primary aim of the survey at the Kapiwak property was to detect pegmatite zones similar to those identified on
) deposit located adjacent to the north of the Kapiwak South block.
The company noted that it used a ternary image and a K-Means clustering statistical method for targeting 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.
With respect to the Lacorne property, Rock Tech said the surveys aimed to delineate pegmatite exploration targets similar to those identified on Canada Lithium's (TSE:CLQ) Quebec Lithium deposit and Glen Eagle Resources' (CVE:GER) Authier deposit - both of which are located in the same vicinity.
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.
Rock Tech is involved in mineral exploration and has positioned itself to become a near-term producer, supporting the increasing global demand for lithium products.
It has one of the largest lithium land packages in North America, holding a 100 per cent interest in the Georgia Lake project in the Thunder Bay Mining District of north-west Ontario, the Kapiwak project in the James Bay region of northern Quebec and the Lacorne project in the Val d'Or Mining District of eastern Quebec.
In addition to its lithium properties, Rock Tech has a 100 per cent interest in a titanium-iron-vanadium property in the Saint-Urbain area near the St. Lawrence Seaway in eastern Quebec and a nickel-copper-platinum group elements-uranium property in the Sibley Basin area near Nipigon, Ontario.
The company continues to actively evaluate other lithium properties in an effort to strengthen its portfolio of lithium assets.
