Kobe Trend - Rock Chips
Recent infill ground reconnaissance undertaken by the Company's JV partner (Greentech Metals Ltd, ASX:GRE) on the Osborne tenement, has resulted in a number of high grade rock chip results peaking at 1.82% Li2O (as per the Greentech Metals, Ltd, ASX Announcement dated 30 October 2023) at the Kobe trend. Multiple assays reported above 1% Li2O suggests that the Kobe trend has the potential to be a consistent mineralised system over the length of strike, including 1.5km of strike within the Osborne JV tenure. Significant results include:
o 1.82% Li2O, 45ppm Ta2O5 and 80 ppm Nb2O5 (sample 23GT20-509)
o 1.41% Li2O, 131ppm Ta2O5 and 74 ppm Nb2O5 (sample 23GT20-531)
o 1.27% Li2O, 88ppm Ta2O5 and 76 ppm Nb2O5 (sample 23GT20-505)

Drilling
A diamond drill rig will be mobilised to the Osborne JV location shortly to commence drill testing of the pegmatites in the southern portion of the tenement. The initial drill hole will be stratigraphic in nature and will take advantage of previous heritage cleared drill sites for its location. The hole is designed to investigate the mineralogy, lithium grade, dip and thickness as well as other attributes of the southern pegmatite zone at depth. This information will be used to refine the planned follow-on drill program which will be focused on both Kobe and Osborne zones and may involve both RC and diamond drilling.
Heritage Survey
The Ngarluma Aboriginal Corporation (NAC) has completed the initial heritage surveys over selected portions of the Kobe and Southern pegmatite zones which will allow RC and Diamond drilling to be undertaken in these areas. It is anticipated that the heritage survey report will be made available during the current quarter and in time to allow the follow-on drill program to get underway. The initial clearances focused on areas with good strike continuity, higher surface grades and wider pegmatite packages. Additional clearances are planned.
This announcement was approved for release by the Board.

Mineral tenement and land tenure status |
· Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. · The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area. |
· The Ruth Well project tenements cover an area of 85km2 and comprises granted tenements: 47/4387, E47/3341, E47/3719, P47/1929 and P47/1998. · The tenements are owned 100% by GreenTech Metals subsidiary company GreenTech Holdings Pty Ltd with the exception of tenement E47/3719 which is subject to a Greentech Metals/Artemis Resources 51%/49% Joint Venture · The tenements are in good standing with DMIRS and there are no known impediments for exploration on these tenements. |
|
Exploration done by other parties |
· Acknowledgment and appraisal of exploration by other parties. |
· Numerous exploration parties have held the area covered by the current GreenTech tenure previously. There is no reported previous exploration for lithium bearing pegmatites on the tenements. · No other exploration companies generated data was used in this release. · Regional RTP aeromagnetics and geology from Geological Survey of WA. · The area was previously explored by Fox Resources Ltd and Artemis Resources Ltd with both focussed on nickel exploration. |
|
Geology |
· Deposit type, geological setting and style of mineralisation. |
· The lithium bearing pegmatite zone trends WNW-ESE and is hosted by strongly sheared sediments of the Regal Formation. · The pegmatites occur as intermittent lenses in strongly sheared sediments assigned to the Regal Formation and are located approximately 3km to the north of the Sholl Shear Zone. · The pegmatites are steeply dipping and up to 20m wide. · The project area is underlain by the Archean Pilbara Craton, specifically the West Pilbara Superterrane (WPST) of Hickman (2016). The 3280-3070 Ma WPST comprises numerous tectonostratigraphic packages (Sholl, Regal and Karratha Terranes and the Whundo and Nickol River Basins) and igneous complexes that have been variously affected by several tectonic events. The easterly to east-north easterly trending Sholl Shear Zone (SSZ) is a boundary for the regional rock packages. Metamorphic grade is higher to the north of the SSZ, suggesting the present-day surface shows a slightly deeper crustal level on the north side.

|
Drill hole Information |
· A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: o easting and northing of the drill hole collar o elevation or RL (Reduced Level - elevation above sea level in metres) of the drill hole collar o dip and azimuth of the hole o down hole length and interception depth o hole length. · If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. |
· Not applicable as no drilling has been undertaken |
|
Data aggregation methods |
· In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. · Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. · The assumptions used for any reporting of metal equivalent values should be clearly stated. |
· Not applicable |
|
Relationship between mineralisation widths and intercept lengths |
· These relationships are particularly important in the reporting of Exploration Results. · If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. · If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg 'down hole length, true width not known'). |
· Not applicable as surface sampling is reconnaissance in nature. |
|
Diagrams |
· Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. |
· All the appropriate maps are provided in the body of this announcement. |
|
Balanced reporting |
· Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. |
· This announcement discusses the findings of recent reconnaissance sampling and associated assays. |
|
Other substantive exploration data |
· Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples - size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. |
· All the meaningful exploration data has been included in the body of this announcement.
|
|
Further work |
· The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling). · Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive. |
· GreenTech plans to conduct further ground reconnaissance and sampling in the short term to determine the surface extent both laterally and along strike and also the economic potential of the prospect. Trenching and drilling will also be undertaken if warranted.
