Copper Lake Resources Ltd (TSX-V:CPL, OTC:WTCZF) has announced results from its winter diamond drilling program on the Marshall Lake copper-zinc-silver VMS property in Northwestern Ontario.
Drilling focused on two new target areas: a prominent magneto-telluric (MT) conductor near high-grade mineralization, and an EM conductor east of the Billiton deposit.
The MT Conductor 1, located near the Billiton deposit, showed strong alteration and moderate to strong conductivity over a vertical range of approximately 700 meters.
One hole, which was drilled to a depth of 802 meters, revealed extensive zones of alteration with moderate disseminated sulphides, returning assays, including 0.27% copper, 1.36% zinc, 39.20 g/t silver, and 0.11 g/t gold over 2.3 meters.
Although no massive sulphides were found, the alteration and mineralization are indicative of a VMS deposit, warranting further drilling.
The second target, the Build-Up Conductor, was identified through a recent large-loop electromagnetic survey and is located in previously undrilled younger rocks.
A drill hole on the target intersected altered volcanic rocks with patchy sulphides but no significant base-metal or precious-metal assays.
Additionally, a borehole electromagnetic (BHEM) survey by Abitibi Geophysics identified a new moderate strength off-hole conductor at 350 meters depth. This New BHEM Conductor, part of the Conductive Centre, expands on previously defined conductors and remains open down-dip, suggesting significant potential for additional high-grade mineralization.
In a statement, Copper Lake CEO Terry MacDonald expressed the need for further drilling to establish continuity within these zones and to explore the extensive alteration and mineralization indicative of a substantial VMS deposit at Marshall Lake.
“Drilling to date has defined a conductive centre of potentially economic size associated with multiple high-grade copper-zinc-silver intersections at reasonable depths,” MacDonald said.
“The drilling results have provided us with additional information to zero in on what we believe is an ore-grade VMS deposit.”
