GG1 is exploring for a stand-alone large tonnage copper, silver, tin and indium resource, or group of resources in this well-endowed and underexplored district. Mt Gossan and Siberia are large scale copper, silver, tin and indium targets. Initial reconnaissance including XRF analysis confirmed an extensive gossanous breccia outcrop at Mt Gossan and widespread mineralisation, including extensive historic mining centres over several kilometres on the Siberia vein system. Significant copper, silver, tin and indium anomalism was confirmed by XRF results. Conventional rock chips were taken for laboratory analysis with results pending. The Herberton area is best known for historic tin mining, however the mineral field also contains a large copper and silver dominant zone in which GG1’s tenements are located, and a separate silver, lead and zinc dominant zone (Figure 1). The latter has been successfully explored by Iltani and Dover Castle, each defining large, nationally significant silver-lead-zinc-indium resources. GG1 aims to replicate the exploration success of neighbouring companies, identifying similar large scale opportunities in the copper, silver, indium and tin dominant zone, where success is leveraged to electrification and AI. The reconnaissance sampling detailed in this announcement supports the prospectivity of Mt Gossan and Siberia for large scale copper, silver, tin and indium mineralisation.

ASX code:GG1 Contact: Quentin Hill – Managing Director Web: greengoldminerals.com.au Email: qhill@greengoldminerals.com.au GREEN & GOLD MINERALS Page 3 Mt Gossan The Mt Gossan prospect is part of the 5km east-west striking mineralised Siberia lode structure, and is characterised by a gossanous and quartz stockwork-veined breccia and multiple occurrences of the Siberia Lode. It is a highly prospective target for larger breccia style thickening of mineralisation and repeats of the lode structure. The Mt Gossan breccia has never been drilled. The Siberia lode outcrops to the north and east of the breccia, where it is approximately 2m thick and was mined via the Mt Gossan mine adit on the northern slope of Mt Gossan and via a series of shafts and drives on the eastern slope. An lode repeat has been mapped by previous explorers in the mine adit and at surface. Portable XRF readings on material collected at the Mt Gossan mine adit dump, along with several gossanous breccia and vein outcrops, returned values of up to 24% Cu and 71 g/t Ag. Elevated Indium values were recorded across all samples, with a maximum value of 576 g/t In recorded in breccia outcrop from Mt Gossan. The XRF results indicate that the gossanous surface outcrops have likely undergone supergene leaching of copper and silver, with residual enrichment in arsenic resulting from surficial weathering processes. In contrast, rock samples sourced from mine dumps from underground workings beneath these surface outcrops returned higher copper and silver values and relatively lower arsenic values.

Historic drill holes reported 2-3m intercepts of copper, silver and tin mineralisation, which is interpreted to be close to true width due to the shallow northward dip of the Siberia lode. Historic drilling results demonstrate consistency in both thickness and grade of the mineralisation; see announcement 4 Feb 2026: Future Facing Metals Acquisition Ag-Cu-Sn-Au-In: • SPH4: 2m at 1.5% Cu, 50g/t Ag, 1.1% Sn, 4.1% Zn from 29m • SPH5: 2m at 0.8% Cu, 23g/t Ag, 0.2% Sn 25m • SPH6: 2m at 0.4% Cu, 13g/t Ag, 0.1% Sn, 0.7% Zn from 20m • SPH7: 3m at 1.9% Cu, 46g/t Ag, 0.5% Sn, 0.6% Zn from 22m • SPH8: 2m at 1.4% Cu, 35g/t Ag, 0.1% Sn, from 27.5m • SPH9B: 2m at 1.8% Cu, 34g/t Ag, 0.5% Sn, 0.8% Zn from 38m Investors should be aware that the historic drill results cannot be verified and are not suitable for use in any future resource estimate.

Note to investors: portable XRF analysis is a spot measurement and does not represent the average insitu grade of the mineralisation. ASX code:GG1 Contact: Quentin Hill – Managing Director Web: greengoldminerals.com.au Email: qhill@greengoldminerals.com.au GREEN & GOLD MINERALS Page 5 Historic drilling was too shallow to test for potential repeats of the Siberia vein and did not target the Mt Gossan Breccia. GG1 considers the Mt Gossan Breccia to be highly prospective for thicker breccia-style mineralisation and lode structure repeats, which remain untested by historical drilling. Preparations for drilling Mt Gossan are underway with drilling planned after the upcoming Copper Hills drill program. XRF analyses of gossanous breccia outcrop returned consistently elevated copper, tin and arsenic with elevated silver and indium present in some samples. Historic rock chip sampling of the breccia returned a maximum value of 1.97 g/t Au highlighting the potential for gold as an accessory metal. The Mt Gossan Breccia The Mt Gossan breccia consists of a monomict clast supported brecciated sandstone with common iron oxide (after sulphide) infill forming a large gossanous breccia across the top of Mt Gossan. Sheeted and stockwork quartz veins with iron oxides after sulphide centre lines occur within the breccia. The breccia has a mapped extent of 220m by 125m and is anomalous in Cu-Sn-Ag-In-Au, making it a highly prospective drill target. Figure 3 Oblique section through Mt Gossan and historic drilling showing the apparent dip of the Siberia lode. True dip is estimated at ~40 degrees. Refer Figure 2 for section location. ASX code:GG1 Contact: Quentin Hill – Managing Director Web: greengoldminerals.com.au Email: qhill@greengoldminerals.com.au GREEN & GOLD MINERALS Page 6 The breccia is a highly prospective target for copper, silver, tin, indium and gold.

The Siberia lode outcrops continuously between Mt Gossan and Siberia and thickens in the Siberia area with the addition of a hanging wall lode. Several historic drill intercepts support the potential to define a resource. XRF Analysis of Mine Dump Samples Samples from the mine dumps were analysed onsite by portable XRF, returning results of up to 24.7% copper, 293 g/t silver, 4.2% tin, 558 g/t indium, 0.2% tungsten and 3.7% zinc.

ASX code:GG1 Contact: Quentin Hill – Managing Director Web: greengoldminerals.com.au Email: qhill@greengoldminerals.com.au GREEN & GOLD MINERALS Page 9 The Siberia lode dips at between 35 and 55 degrees to the north at the Siberia mine area. A series of historic mine adits are driven into the vein over an 800m strike length at Siberia and are reported to have produced copper and silver ore, which was transported to the Chillagoe smelter for treatment. Siberia Historic Drill Results Historic drilling at Siberia returned several significant intercepts including: • SPH15: 8m at 2.6% Cu, 39 g/t Ag, 0.3% Sn from 15m • SPH22: 6m at 1.2% Cu, 31 g/t Ag, 0.2% Sn from 33m • SPH21: 3m at 0.7% Cu, 77 g/t Ag, 0.7% Sn, 4.7% Zn from 20m • SPH13: 1m at 10.2% Sn from 14m Investors should be aware that the historic drill results cannot be verified and are not suitable for use in any future resource estimate. Investors are advised to not place undue reliance on historic drill results. Several historic holes are interpreted to be too shallow to reach any mineralisation or have only tested the thinner hanging wall lode and not the main Siberia lode. Historic drill intercepts were reported only as significant intersections and 1m interval assays are not available. The reporting cutoff grade and internal dilution assumptions are not known. Figure 9 The Siberia mine adit entry into the Siberia lode looking east. The Siberia lode is near continuous for 5km of strike. ASX code:GG1 Contact: Quentin Hill – Managing Director Web: greengoldminerals.com.au Email: qhill@greengoldminerals.com.au GREEN & GOLD MINERALS Page 10 Historic drilling returned a very high grade tin intercept of 1m at 10.2% tin from 14m in SPH13 which is interpreted to be depleted of copper and enriched in tin due to weathering. The mineralisation transitions from shallow tin and arsenic dominant in the gossanous outcrop to copper-silver mineralisation below the gossan. The Siberia lode is open at depth and along strike, with only a small extent tested by historic drilling. Figure 10 The Siberia area showing the mapped Siberia lodes, historic drill results and XRF rock chip results. ASX code:GG1 Contact: Quentin Hill – Managing Director Web: greengoldminerals.com.au Email: qhill@greengoldminerals.com.au GREEN & GOLD MINERALS Page 11 Down Dip Extension: Magnetic Target The Siberia lode outcrop coincides with a series of east–west striking magnetic high anomalies that align with the mapped lode position and progressively decrease in intensity toward the north in the dip direction of the lode. The geometry of the magnetic response is interpreted to reflect a magnetic body dipping to the north and plunging to the north-east. Historic drilling undertaken by Loloma Mining in 1980 reported that magnetic pyrrhotite was present in fresh rock in the Siberia lode. Loloma interpretated that the magnetic anomalies were directly related to the mineralisation. GG1 interprets that these magnetic anomalies represent the down-dip continuation of the Siberia lode, highlighting the potential to extend the mineralisation at depth. Figure 11 Cross section through historic drilling at the Siberia Lode at the Siberia mining area. Refer Figure 10 for location. ASX code:GG1 Contact: Quentin Hill – Managing Director Web: greengoldminerals.com.au Email: qhill@greengoldminerals.com.au GREEN & GOLD MINERALS Page 12 Siberia and Mt Gossan Geology The Siberia lode is interpreted to have formed during cooling and contraction of the Emuford Granite, which generated tension fissures within the country rocks proximal to the granite contact located approximately 400m south of the Siberia lode. This structure was exploited by magmatic hydrothermal fluids resulting in polymetallic vein and breccia mineralisation. Siberia is hosted within sandstone units and is sub-parallel to the contact of the Emuford Granite to the south. The Emuford Granite forms part of the highly prospective O’Brien’s Creek Supersuite of late Carboniferous granites (Kumar, 2022), a regionally significant intrusive suite associated with tin, base metal and gold mineralisation throughout northern Queensland. The Siberia lode system demonstrates substantial lateral continuity and is considered prospective for continued mineralisation at depth along the granite contact. Figure 6 The Mt Gossan - Siberia area over RTP magnetics showing magnetic anomalies coinciding with mineralisation outcrop and the down dip magnetic target that is interpreted to be the continuation of shallow dipping mineralisation to depth.

These examples should not be taken as limiting the broad meaning of sampling. • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • Aspects of the determination of mineralisation that are Material to the Public Report. • In cases where ‘industry standard’ work has been done this would be relatively simple. • Portable XRF results at Mt Gossan and Siberia are spot measurements of rock fragments from the mine dumps and from exposures at surface and in mine shafts and adits. These measurements do not represent averages of the mineralisation. • Historic soil results at Mt Gossan – Siberia were collected by Loloma Mining in 1980. There is no record of the sampling technique used by Loloma Mining. Drilling techniques • Drill type (eg core, reverse circulation, open- hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc). • Loloma Limited drilled 31 RC percussion holes at Siberia – Mt Gossan trend. The drill diameter is not stated in historic reports. Drill sample recovery • Method of recording and assessing core and chip sample recoveries and results assessed. • Measures taken to maximise sample recovery and ensure representative nature of the samples. • Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. • No record is available of drill sample recovery in historic reports. Logging • Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. • Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. • The total length and percentage of the relevant intersections logged. • No lithology logs have been located for Loloma Mining drilling. Sub- sampling techniques and sample preparation • If core, whether cut or sawn and whether quarter, half or all core taken. • If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. • For all sample types, the nature, quality and appropriateness of the sample preparation technique. • Quality control procedures adopted for all sub- sampling stages to maximise representivity of samples. • Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling. • Whether sample sizes are appropriate to the grain size of the material being sampled. • No record has been located of the sampling technique for RC drilling by Loloma Mining. Quality of assay data and laboratory tests • The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. • For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. • XRF analysis was performed using an Hitachi MET-8000 device in Mining- FP mode using a 30 second measurement duration. The instrument was recently calibrated by the OEM. • XRF measurements are not as accurate as laboratory assays and do not reliably predict average insitu grades. XRF measurements are intended to confirm which metals of economic interest are present rather than the average grade of the mineralisation.
