The board of directors of Greentech Technology International Limited provided an update on ongoing near mine exploration at the Renison Tin Operations (Renison) in Tasmania, Australia, in which the Company through YT Parksong Australia Holding Pty Limited (YTPAH), an indirect non- wholly owned subsidiary of the Group, has a 50% equity interest. Renison is managed by Bluestone Mines Tasmania Joint Venture Pty Ltd. (BMTJV). Metals X Limited, a company incorporated in Australia with limited liability and the shares of which are listed on the Australian Securities Exchange, owns another 50% equity interest in Renison though its 50% stake in BMTJV.

HIGHLIGHTS (100% basis): Ongoing surface exploration drilling at the Ringrose Prospect, located 750m south of existing Renison mine development, continues to intersect additional significant tin mineralisation. Current Ringrose mineralised extents are approximately 300m along strike length and 200m down dip with mineralisation remaining open to the north, south and at depth. Following the initial S1671 discovery drill hole at Ringrose, which intersected 26.93m down hole width @ 4.57% Sn from 225.07m, another seven surface diamond drill holes targeting Ringrose mineralisation have been completed.

Results from three of the five-holes were reported in July 2023: S1675: 11.5m (ETW) @ 1.27% Sn from 173.6m, S1679: 8m (ETW) @ 1.49% Sn from 136.1m, S1681: 3m (ETW) @ 1.21% Sn from 218.9m. Additional significant Sn assay results now received include: S1675: 5.5m @ 1.34% Sn from 41.5m; S1678: 2.4m @ 1.05% Sn from 46.2m and 5.1m @ 0.61% Sn from 246m; S1682: 1.0m @ 1.2% Sn from 184m and 1.8m @ 0.75% Sn from 286.2m; S1684: 7.6m @ 0.66% Sn from 167.9m and 5.6m @ 0.92% Sn from 225.1m. Ringrose drill core assay results also reported anomalous gold results including: S1675: 2.4m @ 0.52g/t Au from 1,109.6m; 5.6m @ 0.16g/t Au from 1,195.7m; 3.15m @ 0.40g/t Au from 1,225.6m; 1m @ 1.35g/t Au from 1,239m; S1679: 3m @ 0.51g/t Au from 142m; S1682: 0.7m @ 0.58g/t Au from 60.4m; S1684: 2m @ 0.40g/t Au from 286.21m.

Significant success from recent downhole electromagnetic ("DHEM"), and surface fixed loop electromagnetic ("FLEM") surveys completed at Ringrose. Multiple large and highly conductive zones identified with several considerably large, extremely conductive zones identified which are completely untested. Results from the recent DHEM and FLEM surveys confirm that the combination of these two methods is exceptionally well suited to identifying mineralisation at Renison to significant depth.

Further DHEM on current and ongoing drilling, and additional FLEM surveys are planned. Drilling Results: 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.

S1671 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, seven additional follow-up drill holes for 3,122m were completed at Ringrose to test the extent of this mineralisation. Partial results from the follow- up program were reported in July 2023, and included; S1675: 11.5m (ETW) @ 1.27% Sn from 173.6m; S1679: 8m (ETW) @ 1.49% Sn from 136.1m; and S1681: 3m (ETW) @ 1.21% Sn from 218.9m.

Further remaining assay results have been returned for the Ringrose follow-up drillholes with additional positive tin intercepts including: S1675: 5.5m @ 1.34% Sn from 41.5m; S1678: 2.4m @ 1.05% Sn from 46.2m and 5.1m @ 0.61% Sn from 246m; S1682: 1.0m @ 1.2% Sn from 184m and 1.8m @ 0.75% Sn from 286.2m; S1684: 7.6m @ 0.66% Sn from 167.9m and 5.6m @ 0.92% Sn from 225.1m. Remaining assays for S1684 and S1683 and all of S1685 are expected by the first quarter of 2024. High-grade tin mineralisation currently extends over 300m strike length, 200m depth extent and is open to the north and south.

Reported mineralisation is broadly coincident with the modelled DHEM conductors, however orientations are inconsistent between drill hole intersections. The mineralised zone is structurally complex and interpretation is ongoing with the aid of newly acquired DHEM and FLEM survey data, as well as further drilling. Gold mineralisation was also identified at Ringrose, with several anomalous gold intercepts returned.

The association of gold at Ringrose and its significance is currently under investigation. A second DHEM program was completed by BMTJV in October 2023 and eleven recent surface exploration holes were surveyed, including the five recent holes drilled at Ringrose. A FLEM survey covering 12-line km with 204 measurement stations was also completed in the Ringrose area and areas south and south-west of Renison in conjunction with the DHEM survey.

A final report and conductor models from the Ringrose area down hole and surface EM surveys were received in January 2024 with highly encouraging results. Conductor models and final reports for the south and south-west sections of the DHEM and FLEM survey areas are expected to be received by the end of the first quarter of 2024. The combination of FLEM and DHEM surveys have proven to be an efficient and effective targeting tool for Renison-style tin mineralisation.

Modelling of results from both EM methods correlate exceptionally well with each other, showing several large, highly conductive zones. This implies significant extensions to the mineralisation intersected in recent surface exploration drilling. The DC target is designed to test a poorly constrained but significant off-hole conductor identified by DHEM in 1986 in drill hole S1182.

The target is stratabound or fault hosted tin bearing massive sulphide ore within the prospective dolomite units of the Renison Bell Mine Sequence adjacent to an interpreted north-striking fault. This program will comprise a 700m diamond drill hole, followed by DHEM. The Tunnel Hill Target will test a magnetic high and DHEM conductivity models associated with a regionally significant north-west trending modelled fault.

A previous drillhole completed in 1995 intersected 2.4m @ 1.85% Sn from 468.5m at the fault intersection. Drilling will target the re-modelled 1995 conductor models with two diamond drill holes for 1200m and subsequent DHEM surveys.
