Rock Tech says latest drill results show “very promising” subsurface widths
Rock Tech Lithium (CVE:RCK) on Tuesday unveiled the latest drill results from its Lochaber graphite property in Quebec, with intercepts returning up to 5.79% graphitic carbon (Cg).
The results are from a 4,600-metre program announced last December, and include both step out and infill holes, primarily focused on electromagnetic conductors "A" and "C".
These conductors were found on the Plumbago area of the property during geophysical surveys last September.
Notable results announced today included 7.00 metres of 2.06% Cg in hole PB-12-20, while hole PB-12-20A intersected 165.79 metres of Cg at two levels, with grades ranging from 1.41% Cg to 2.21% Cg, including 127.52 metres at 2.21% Cg.
Meanwhile, hole PB-12-21 returned 14.13 metres of Cg at various depths with grades ranging from 1.68% Cg to 5.79% Cg, including 4.13 metres at 5.79% Cg.
Rock Tech said that hole PB-12-20 was terminated at a depth of 33 metres and was re-drilled as PB-12-20A at an adjacent location. These drill holes further tested electromagnetic conductor "C" while drill hole PB-12-21 tested the southern extension of electromagnetic conductor "A".
"The drill results from electromagnetic conductor "C" are showing very promising subsurface widths,” said VP of exploration and interim CEO Afzaal Pirzada.
“We continue to build a 3D model of the graphite mineralization intercepted in trenches and drill holes and will begin resource estimation procedures once the complete set of assay results are received from the lab.”
Rock Tech says that to date, it has received results for 21 drill holes and seven trenches. Assay results for the remaining 14 drill holes completed during the fourth quarter of 2012 are pending, along with resubmitted core samples from the first phase of drilling.
The company's geophysical surveys and drill programs have focused exclusively on the Plumbago area of the property, which includes only four of the 32 claims subject to the property option agreement.
A maiden NI 43-101 resource estimate is being planned for Lochaber, which will be based solely on this area.
But further upside potential exists, as surface samples taken from the Kelly, McLaren and Burke areas of the property returned graphite results up to 22%, the junior explorer said.
