The Kobe Prospect sits within the Company’s Ruth Well Project tenements, in the West Pilbara region of Western Australian. A total of 65 samples have been collected from the project area and assayed to date.
The results from the recent 43 additional reconnaissance rock chip samples submitted for analysis, returned excellent grades of lithium mineralisation measuring up to 1.8% Li2O.
Ground reconnaissance has also confirmed that the Kobe pegmatite bearing zone extends beyond the previously reported 6km strike, to a strike of 7.5km.
Management Commentary
Executive Director Thomas Reddicliffe commented:
“These recent additional reconnaissance samples are a follow up from the original program, so we are extremely pleased to see a persistence in the tenor of the mineralisation over the entire length of the pegmatite zone identified to date. We believe the consistency of the grades over a now 7.5km strike is evidence of a large mineralising system and underscores the prospectivity of this pegmatite zone.
GreenTech has a strong foothold in one of WA’s exploration hotspots and with high-quality lithium and copper projects in its portfolio, Greentech is exceptionally well placed to capitalise on the decarbonisation and energy economy transformation that is now taking place around the world.”
Ruth Well Project Reconnaissance Program Summary
The second reconnaissance sampling program has followed on from the first reconnaissance program which comprised 22 samples, the results of which were reported previously. This second program targeted the pegmatite zone over a further 5.5km and extended into GreenTech’s adjoining tenements with a total 43 samples collected. The pegmatite was tracked into tenement E47/3719 which is under the Osborne Joint Venture (51% Greentech (manager) and 49% Artemis Resources). The variably exposed pegmatite zone has been sampled opportunistically over the currently observed strike length of 7.5km. Within the pegmatite bearing zone individual pegmatites of variable width up to 4m were observed.
This follow-up batch of 43 samples were dispatched to the ALS Global laboratory in Perth for a 52-element analysis with 37% of the samples returning positive results for lithium mineralisation and including 20% with assays reporting greater than 1% Li2O. Test work carried out by Curtin University by way of XRF analysis on a sample from the first sampling program confirmed that the lithium bearing mineral is spodumene. For completeness, three of the lithium bearing samples from the second program have also been submitted to Curtin University for confirmation of the mineralogy. The results for these samples will be reported when the analytical results are received. It is not anticipated that there will be a change in the nature of the lithium mineralogy. The following significant sample assays were received for the second program;
- Sample No 23GT11-041 - 1.80% Li2O
- Sample No 23GT11-042 - 1.70% Li2O
- Sample No 23GT11-039 - 1.58% Li2O
- Sample No 23GT11-022 - 1.54% Li2O
- Sample No 23GT11-016 - 1.53% Li2O
- Sample No 23GT11-017 - 1.53% Li2O
- Sample No 23GT11-040 - 1.48% Li2O
- Sample No 23GT11-013 - 1.04% Li2O
- Sample No 23GT11-018 - 1.0% Li2O
- Sample No 23GT11-004 - 0.87% Li2O
- Sample No 23GT11-032 - 0.57% Li2O
- Sample No 23GT11-012 - 0.49% Li2O
- Sample No 23GT11-018 - 1.0% Li2O
- Sample No 23GT11-043 - 0.22% Li2O
- Sample No 23GT11-011 - 0.22% Li2O
- Sample No 23GT11-038 - 0.20% Li2O

Forward Exploration Program
Sampling and mapping are continuing and are aimed at defining the spatial extent of the pegmatite zone and the consistency of the lithium mineralogy and grade within the mineralised system.
Preparations relating to regulatory requirements have also commenced to enable the undertaking of a maiden drilling program. Details of these programs will be released to market after receipt of approvals.

EIS Grant for Minnie Springs Copper Porphyry Drilling
- Augustus Minerals has been granted a co-funded drilling grant of up to $110,000 for 2 x 700m deep diamond drill holes under the WA Government’s Exploration Incentive Scheme (EIS) for the Minnie Springs prospect.
- The deeper diamond drill program is designed to test and to provide a 550m deep, 1km wide geological/geochemical/structural cross-section through the large 3km long by 1km wide copper moly porphyry system, linking the Mo mineralised leucogranite to the extensive Cu in soil anomaly to the northeast.
- Previous RC drilling at Minnie Springs intersected mineralisation, geology and alteration halo consistent with the zoning of a large porphyry copper / moly system.
Andrew Ford, GM Exploration
“The Company is pleased to receive an EIS grant to complete deeper drilling at the Minnie Springs Copper Molybdenum Project. The resultant data will enable mapping of the lithology and alteration to a depth of 550m and potentially intersect, or provide vectors to, higher grade Mo-Cu mineralisation using a Mo-Cu porphyry geological model”.
Minnie Springs
Minnie Springs hosts porphyry related copper molybdenum mineralisation previously drilled and defined by Catalyst Metals. A molybdenum Exploration target has been defined for the historicdrillingareacomprisedofbetween12-84Mtasoutlinedbelow (Table 1 and Figure 1, 2.)1.
Table 1. Exploration target size estimate for Minnie Springs Molybdenum depositNote: Based on ~300 ppm cut-off at 100% recovery.
The potential quantity and grade of the exploration target is conceptual in nature, there has been insufficient exploration to estimate a Mineral Resources, and it is uncertain if further exploration will result in the estimation of a Mineral Resource.
The planned diamond drilling will complement the recently completed 3,200m RC drilling program that infilled around hole MSRC012 (18m @ 0.37% Cu and 9.7 g/t Ag from 94m downhole, and 16m @ 0.38% Cu and 19.4g/t Ag from 121m downhole2) and tested the northern half of the 2km long copper-in soil anomaly. Assays from this program are expected to become available over the next month.
The limited exploration in the region, highlighted by 95% of the Ti-Tree project having no previous exploration, demonstrates the prospectivity of this underexplored mineral province.

Quarterly Activity Report 31 March 2024
Figure 1. Fiery Creek Copper Prospect/Yataga Granodiorite summarizing rock (brown diamonds) and termite mound sample results (black crosses)
Continuing with its primary exploration focus on the Georgetown project in the latter half of 2023, EMU received assay results during the quarter from its second, in field reconnaissance work. The geochemical sampling programme covered the Fiery Creek high grade copper vein swarm and the Snake Creek prospects with significant element results returned from the Fiery Creek Copper (elevated Cu-Au-Ag-Bi-In-Pb-Sb-Te) and Snake Creek (elevated Pb-Ag-Au-Sb).
Whilst the survey was cut short due to inclement weather, EMU was encouraged by the significant success reflected in the assays results. The results from mineralogical studies confirmed EMU’s interpretation of an indicative, scale Copper-Porphyry system at the Fiery Creek prospect and was a highlight of the survey with new information building on the scale and potential of the prospect1.
Assay results returned included:
- Fiery Creek rock assay results up to 23.5% Cu, 0.27ppm Au, 460ppm Ag, 1.9% Bi, 89ppm In, 2.7% Pb, 667ppm Sb, 1470ppm Zn2.
- evidence of strong potential for the presence of critical and strategic minerals (Cu, Bi, In), with precious and base metals.
- evidence of alteration mineralogy, mineralisation geochemistry and areal extent of the Fiery Creek quartz-Cu-Bi vein swarm strongly suggesting a previously unrecognised subjacent porphyry Cu-Mo system.
- Yataga Granitoid Complex termite mound and coincident rock chip sampling returned several anomalous polymetallic zones for follow up.
- Snake Creek Prospect assays returned 0.20ppm Au, 390ppm Ag, 22.4% Pb, 464ppm Sb1.
Significant results were returned from the Fiery Creek Copper prospect with elevated Cu-Au- Ag-Bi-In-Pb-Sb-Te and from the Snake Creek prospect with elevated Pb-Ag-Au-Sb.
The elevated pathfinder element results and a macro-petrology assessment3 of rock samples completed by Mr Nigel Maund, Consulting Economic Geologist, from the previously unexplored Fiery Creek Prospect, point to the discovery of a porphyry copper system.
The sampling program assessed a number of high-priority prospects within the Georgetown Project tenements utilising termite mound and outcrop rock chip geochemistry. A total of 46 rock chip and 489 termite mound samples were collected across eight prospects.
