Greentech restarts copper-zinc drilling at Whundo

GreenTech is back on the ground at Whundo carrying out its 4,000m diamond drilling program
The program is focusing on the potential to significantly increase the 6.2Mt resource
Downhole electromagnetic surveys will follow on selected holes

Special report: West Pilbara explorer GreenTech Metals has returned to its Whundo copper asset to drill test a host of untested conductors associated with mineralised copper shoots.

The 4,000m Stage 2 drilling campaign kicked off in December last year to expand on the existing 6.2Mt resource at 1.12% copper and 1.04% zinc but took a short break over Christmas and the New Year period.

The program is homing in on the down-plunge conductor targets associated with mineralised shoots at Austin, Shelby, Yannery and Ayshia.

Downhole electromagnetic (DHEM) surveys will follow on selected holes, the results of which will assist in the planning of follow-up drill holes which may be undertaken as part of this current drill program.

GreenTech Metals (ASX:GRE) said the overall aim is to quantify new resources with the targeting guided by results of the Stage 1 drill program that resulted in the identification of down-plunge conductor plates within the existing Whundo/Ayshia resource.

Growth opportunities looming

Stage 1 drilling in September last year confirmed the continuity of mineralisation at Whundo with 16m at 1.2% copper, 0.12% zinc and 0.035g/t gold from 230m returned at Austin.

That was deeper than a previous hit of 6m at 2% copper from 226m.

And over at the Ayshia zone, the drill struck 10m at 1.2% Cu, 1.2% Zn and 0.09g/t Au from 260m, with 3m at 3.1% Cu and 2.6% Zn from 261m, deeper than older strikes of 23.7m at 3.2% Cu and 13.97m at 3.4% Cu.

GRE executive director Tom Reddicliffe said the company firmly believes it can continue to expand the Whundo copper resource to underpin a copper project.

With processing options nearby through its alliance with Anax Metals or Artemis Resources’ Radio Hill processing plant, he said GreenTech is well positioned to take advantage of exploration success.

Second phase underway

“The stage 2 drill program is well underway and will be supported with additional down-hole electromagnetics,” Reddicliffe said.

“Fixed loop electromagnetic surveying completed in late December is currently being interpreted and is expected to assist further with targeting of the Stage 2 program.”
