GreenTech Metals (ASX:GRE) has delivered one of the strongest copper hits yet from its Whundo Project in the West Pilbara.
Diamond hole 26GTDD016 returned 4.76m at 7.13% copper, 1.20% zinc, 0.88g/t gold and 29.6g/t silver from 367m.
Inside that sat 3.44m at 9.43% copper, 1.59% zinc, 1.20g/t gold and 39.7g/t silver.
That is the grade, the more important part is where it sits.
Beyond the resource
The new intersection is around 65m down plunge beyond the current Ayshia Mineral Resource envelope.
That makes it more than a high-grade infill result.
It is an extension, and it supports the idea that the mineralised system continues deeper than the existing model suggests.
The hit also sits within a broader 6.85m zone of chalcopyrite-rich massive to semi-massive sulphides.

The grades are improving at depth
Historical drilling had already hinted that copper grades strengthen down plunge.
Previous results included 23.7m at 3.19% copper and 13.97m at 3.4% copper.
The latest hole has now pushed that trend further, with the 3.44m at 9.43% copper representing the highest-average-grade multi-metre copper intersection recorded at Ayshia to date.
That gives GreenTech a clear follow-up target.
Resource growth is the real prize
Ayshia currently hosts 0.9Mt at 1.3% copper and 2.3% zinc.
It forms part of the wider Whundo Resource of 6.2Mt at 1.12% copper and 1.04% zinc.
GreenTech is targeting an updated Whundo Mineral Resource in Q4 2026.
If the deeper high-grade zones keep repeating, that update could become much more interesting.

What comes next
Downhole electromagnetic surveying is planned on 26GTDD016 to help trace the continuation of the high-grade shoot.
More drilling will then test how far the system keeps going.
Assays are also pending from Yannery and Austin, with results expected in October.
The first hole has already done its job, now GreenTech needs to prove how much high-grade copper sits beyond it.
