The board of directors of the Greentech Technology International Limited provided an update on the ongoing near mine exploration at the Renison Tin Operations, in which the Company through YT Parksong Australia Holding Pty Limited, has a 50% equity interest. Renison is managed by Bluestone Mines Tasmania Joint Venture Pty Ltd. Metals X Limited owns another 50% equity interest in Renison though its 50% stake in BMTJV. This update is based on the information provided by Metals X. During 2019, seven surface drill holes were surveyed in a program using a single axis DHEM probe.

This program identified 24 conductor plates, 13 of which were off-hole conductors. An initial program of three diamond drill holes for 2,104m was completed to test the ranked conductors and assessed the potential for DHEM to detect tin bearing sulphide mineralisation. This program was completed during 2022.

A subsequent phase 2 diamond drilling program comprising seven drill holes for 6,246m commenced in August 2022 to test other 2019 DHEM conductors. Drill hole S1671, collared approximately 750m south of existing mine development, was the second of these Phase 2 drillholes and intersected 26.93m (down hole width) @ 4.57% Sn from 225.07m. Following this high-grade intersection, ten additional follow-up drill holes for 5,600m have been completed at Ringrose to date.

Several of these drill holes completed were surveyed with downhole electromagnetic (EM) in November 2023, identifying several new conductive zones. Assay results from six of these holes, and preliminary results from the EM survey were previously reported in the announcements of the Company (on 5 July 2023 and 27 February 2024). Additional significant Sn assay results now received from the ongoing follow-up drilling include: S1683: 2.9m @ 0.9% Sn from 143.3m; 5.6m @ 1.2% Sn from 158.6m; and 6.85m @ 0.69%Sn from 181m; S1684: 9.9m @ 0.53% Sn from 244m; S1685: 3.8m @ 3.38% Sn from 13.2m, 2m @ 0.80% Sn from 27m; 2.1m @ 1.01% Sn from 48.9m; 9m @ 0.60% Sn from 56m; 7.7m @ 0.41% Sn from 145.2m; S1687: 7.2m @ 2.52% Sn from 249.4m; S1688: 6.45m @ 0.51% Sn from 201m; 12.05m @ 1.01% Sn from 213.15m; S1696: 8.4m @ 0.87% Sn from 42.5m (NB drilling is ongoing).

High-grade tin mineralisation currently extends over approximately 300m strike length, 250m depth extent and is open in all directions, with extensional drilling continuing. Reported mineralisation is broadly coincident with the modelled DHEM conductors, however conductor orientations currently vary between drill hole intersections. Drill core orientations also indicate that the mineralised zone is structurally complex and interpretation is evolving with the aid of newly acquired DHEM and FLEM survey data, as well as further drilling.

Current interpretation indicates an east-west striking mineralised zone with north/north-west- trending high-grade shoots. Drill hole S1696 was collared 100m north of Ringrose and is currently still in progress. The reported intersection for the first part of this drill hole indicates mineralisation at Ringrose extends further to the north and visible mineralisation in this hole currently also extends down hole.

Drillcore for the remainder of drill hole S1696 will be sampled and assayed on completion and remaining assays for S1688 are pending. Results for these drill holes are expected in June 2024. Infill and extensional drilling at Ringrose are ongoing with currently planned programs expected to be completed by the third quarter of 2024.

Additional results will be announced on completion of these programs. FUTURE PLANNING: Drilling - Ringrose: Two surface diamond drill rigs are currently drilling exploration targets at Renison. A closer- spaced infill program of ten surface diamond drill holes for a total of 2,800m is in progress at Ringrose and expected to be completed by the third quarter of 2024. Drill holes are designed to further test the extent and grade of mineralisation at Ringrose, with three holes extended past the mineralisation target to test recently modelled conductors.

Collar locations and hole traces for this ongoing program are shown in Figure 4. In addition to the standard Renison core logging, processing and multi-element exploration assay suite, selected ore grade intersections will also be submitted for mineralogical analysis and preliminary metallurgical test work including modal mineral analysis (MLA) and bond work index testing. A second drill program drilling north and south along strike of the Ringrose mineralised zone is also progressing and these drill holes were designed to test the modelled strike extent of the mineralised zone with additional support from EM conductor models from the recent EM surveys at Ringrose. A total of five surface diamond holes for 2,100m is currently in progress for this program which is also expected to be completed by the third quarter of 2024.

On completion of modelling and interpretation of the EM survey data, further drill targets are expected to be generated and drill tested in the second half of 2024 with a continued focus on the Ringrose target area.
