GreenTech hails massive sulphides in Whundo core, | Australian Markets

GreenTech Metals has hailed important outcomes from its first two diamond drill holes for 1187 metres at its Whundo volcanogenic copper-zinc project south of Karratha, together with 7.14m at 1.46 per cent copper and 1.23 per cent zinc from 277.16m.

The intercept from the company’s unmined Austin conductor goal consists of 6.3m going 1.84% copper and 1.4% zinc from 278m, together with 3.45m assaying 2.42% copper and a couple of.41% zinc from 278m.

GreenTech put a second gap into the never-mined Shelby conductor, coring out 9.94m going 1.32% copper and 0.18g/t gold from 598.2m, together with 6.34m at 1.68% copper and 0.16g/t gold from 598.2m, and a couple of.5m operating 2.21% copper, 0.16% zinc and 0.08g/t gold from 602m.

It additionally intercepted one other 3.69m grading 1.18% copper and 0.35g/t gold from 626.3m.

Only hint gold was picked up in the Austin intercepts, between 0.08 and 0.1g/t.

GreenTech’s drill program is exploring a sequence of northward-plunging conductor plates, which might characterize extensions to recognized mineralised shoots alongside the two kilometre Whundo mineralised pattern, which incorporates the Austin, Shelby, Yannery and Ayshia zones. The company goals to establish elevated useful resource potential at Whundo.

The program started in December and skilled delays because of cyclonic climate and a few required changes to the Shelby drilling to keep the deep gap on observe to its goal.

The Shelby gap ran to a complete depth of 815.7m and the Austin gap attained 371.4m. Both holes had been drilled at an inclination of 67 levels however on completely different azimuths.

GreenTech was rewarded with each holes intersecting massive to semi-massive sulphide comprising chalcopyrite (copper iron sulphide), sphalerite (zinc-iron sulphide), pyrrhotite (a magnetic iron sulphide) and the iron sulphide, pyrite.

The intercept depths are according to the interpreted down-dip extensions of beforehand intercepted mineralisation and in addition with the interpreted conductor places.

These outcomes proceed to verify the high copper and zinc grades discovered on the previous Whundo copper mine, which was final mined in 2006.

The Shelby gap intersected massive, semi-massive, disseminated and blebby sulphides from 598.1m to 608.14m, representing an intercept that’s close to 9.94m true width.

The Austin gap intersected massive and semi-massive sulphides from 277.17m to 284.3m, which represents close to true width of 7.14m.

We are very inspired with these outcomes which affirm our visible affirmation of massive to semi-massive sulphides containing copper and different metals related to the conductor targets examined at each Shelby and Austin. The outcomes affirm that these two mineralised shoots are persevering with down plunge and current a great alternative to increase the Whundo project assets.

GreenTech has accomplished down gap time area surveys in each drill holes. Southern Geoscience consultants interpreted the outcomes, alongside different geophysical surveys accomplished in 2024.

The new geophysical model at Shelby locations the conductor source instantly west of the latest sulphide pierce level, extending past the boundaries of the 2024 floor survey. Southern Geoscience has really useful it for additional testing.

Surface geophysics at Austin helps good potential for a higher plunge extent and locations the centre of the conductor source about 50m west/northwest of the latest sulphide pierce level.

That goal has additionally been really useful for testing, together with extra step-out holes to check the bigger plunging conductor.

The current drilling program at Austin and Shelby has offered helpful and detailed geology that permits relative stratigraphic positioning of the mineralised horizons.

As half of an upcoming stage two drill program, the realm between Austin and Shelby will probably be focused for potential continuity of the copper mineralisation between the 2 shoots, neither of which have been beforehand mined.

The two mineralised shoots’ proximity, common plunge and lateral dip raises the chance they might merely be two more conductive elements of a single mineral shoot.

GreenTech says it’ll additionally now assess its drill outcomes for crucial metals after figuring out elevated gallium to 114 elements per million in a number of samples from each drill holes and close to the copper mineralisation.

The average abundance of gallium in the earth’s crust is comparatively low, usually much less than 19ppm. This curious metallic doesn’t happen as a free aspect in nature however is usually recognized in compounds, similar to bauxite and sphalerite.

GreenTech’s stage two drilling program will proceed to hunt out a important growth of the prevailing of the 6.19 million tonnes at 1.12% copper and 1.04% zinc Whundo/Ayshia mineral useful resource and the place potential, establish new assets.

The present buoyant copper price has led the company to think about near-term alternatives for potential copper manufacturing from Whundo.

The imminent program will give attention to testing the down-plunge and lateral extents of the Austin shoot, the lateral extents of the Shelby shoot, the down-plunge extent of the Ayshia shoot and the higher high-grade oxide zone at Yannery.

It may even put in a core gap at Whundo to supply materials for metallurgical take a look at work.

GreenTech will plug the latest drill outcomes into a conceptual Whundo mine examine to evaluate the economics of near-term manufacturing alternatives and it’ll additionally assess the Radio Hill processing web site as an option for Whundo ore therapy.

The company figures the present targets related to recognized mineralised shoots might considerably increase the present copper-zinc useful resource.

But for now, drilling and interpretations up to now level to important growth potential that may very well be realised with additional drilling alongside strike and at depth.
