Greentech Metals Limited Announces an Update on Exploration Activities At the Munni Munni Platinum-Palladium-Copper-Nickel Project in the West Pilbara Region of Western Australia

Alien Metals Limited advised that its joint venture partner, GreenTech Metals Limited ("GreenTech"), has announced an update on exploration activities at the Munni Munni Platinum-Palladium-Copper-Nickel Project in the West Pilbara region of Western Australia. GreenTech has identified material upside potential not captured in the historic Mineral Resource Estimate (MRE) of 24Mt @ 2.9 g/t PGE4 for 2.2Moz. Identification of high-grade PGE zones (>4 g/t PGE4) and under-recognised Cu + Ni mineralisation. Eastern zones with shallow plunge from surface suggest potential for open-cut mining. Key findings support an expanded re-estimation of the historic MRE1 and reporting in accordance with JORC (2012). GreenTech's maiden drilling and resampling programme concluded in March 2026 with results expected in mid-April 2026. Ongoing review of historical Munni Munni data, comprising core and logs for 396 drill holes, has identified material upside potential not captured in the historic Mineral Resource Estimate (MRE)[1], including: High-grade PGE zones, Under-recognised Cu + Ni mineralisation, Eastern zones with shallow plunge from surface. Key findings support an expanded re-estimation of the historic MRE1 and reporting in accordance with JORC (2012). GreenTech's maiden drilling and resampling programme concluded in March 2026 with results expected in mid-April. Resampling programme of the well-preserved historic Munni Munni drill core expanded to target high-grade extensions of Ferguson Reef. The Munni Munni acquisition was completed on 2 February 2026[2], and GreenTech's maiden drilling and resampling programme concluded in March 2026[3]. This release includes analysis and interpretation of historical drilling results across Munni Munni. Detailed historical drill hole information and the relevant JORC Table 1 disclosures are included in the appendices of this release. GreenTech's ongoing systematic review of the historical Munni Munni database, comprising 328 drill holes, and detailed interrogation of drill logs has identified material upside not captured in the historic Mineral Resource Estimate (MRE) of 24Mt @ 2.9g/t PGE4[6]for 2.2Moz (HLX, 2002)1,[7]. Cautionary Statement- The estimates are historical estimates and are not reported in accordance with the JORC Code (2012); a competent person has not done sufficient work to classify the historical estimates as mineral resources or ore reserves in accordance with the JORC Code (2012); and it is uncertain that following evaluation and/or further exploration work that the historical estimates will be able to be reported as mineral resources or ore reserves in accordance with the JORC Code (2012). Key findings of this work include: High-grade PGE zones identified: Multiple Ferguson Reef zones of +4g/t PGE44have been identified in the historical data, with design of upcoming exploration programmes to include infill and extensional drilling targeting the areas with potential for reef thickening. Cu + Ni mineralisation under-recognised: Drill core inspection and drill log interrogation confirms that Cu + Ni mineralisation presents outside of PGE Reef zones. The historic MRE3only includes Cu + Ni within high-grade PGE reef domains (using a 1.9g/t PGE4 cut-off3), with limited assaying of sulphide zones above and below the reef horizon. Eastern zones with shallow plunge from surface: Review of drill logs in the shallow Eastern zones indicates Cu + Ni sulphide mineralisation is not constrained to the PGE Reef and is sitting in the gabbro hanging-wall units (including from surface), suggesting mineralisation will potentially be amenable to bulk open-cut mining. GreenTech's resampling programme, undertaken for validation of the historic MRE1, has demonstrated the potential upside of Munni Munni beyond the Ferguson Reef. To date, only 16 of the 162 historic diamond drill holes have been re-sampled as part of the Phase 1 programme now complete. As drill core has been extremely well preserved, future exploration work programmes at Munni Munni will include further resampling in addition to drilling to target high-grade extensions of mineralisation of the Ferguson Reef. These findings support an expanded re-estimation of the historic MRE3 following validation of historical information through the QA/QC programme required for JORC (2012) reporting. Assay results for the completed drilling and resampling programme are expected to be reported in mid-April 2026. The historical results presented in this release include exploration results collected between approximately 1985-2021. While drilling and assay QA/QC procedures generally match industry standard at the time the work was done, they are not consistent with current industry practice required to meet the 2012 JORC code for reporting of exploration results. As such these results are stated here to provide an indication of the exploration potential of the Munni Munni project tenements. The estimates of the quantity and grade of mineralisation for the Munni Munni project tenements referred to in this announcement are "historical estimates" within the meaning of the ASX listing rules and are not reported in accordance with the JORC Code 2012. GreenTech notes that a competent person has not done sufficient work to disclose the corresponding exploration results in accordance with the JORC Code 2012; it is uncertain that following evaluation and further exploration work that the historical estimates will be able to be reported as mineral resources in accordance with the JORC Code 2012; it is possible that following further evaluation and/or exploration work that the confidence in the prior reported exploration results may be reduced when reported under the JORC Code 2012; that nothing has come to the attention of GreenTech that questions the accuracy or reliability of the former owner's exploration results, but GreenTech is in the process of independently validating the previous owner's exploration results and therefore is not to be regarded as reporting, adopting or endorsing those results. GreenTech will continue to review and validate the data to enable the results to be reported in accordance with the JORC Code 2012. The levels of PGE (3E), Copper, Nickel reported from past activities, are a key factor in guiding GreenTech's exploration strategy. The previous activity, which produced these results, involved multiple rounds of drilling.
