The board of directors of Greentech Technology International Limited provided an update on the ongoing near mine exploration at the Renison Tin Operations ("Renison"), 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"). This update is based on the information provided by Metals X. Drilling at the Ringrose prospect at Renison continues to intersect significant mineralisation.

Following the initial S1671 discovery drill hole at Ringrose, which intersected 26.93m down hole width @ 4.57% Sn from 225.07m (See the announcement of the Company on 26 September 2022), a further fourteen surface diamond drill holes targeting Ringrose mineralisation have been completed and results from eleven of these holes were reported in previous announcements of the Company on 5 July 2023, 27 February 2024 and 24 April 2024. Additional significant Sn assay results received include: S1686: 87.0m at 0.65% Sn from 204m including: 7.5m at 1.13% Sn from 253.5m;; 5.3m at 0.52% Sn from 268.9m;. 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. 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) at 4.57% Sn from225.07m, with this prospect area now called Ringrose.

Following this high-grade intersection, fourteen additional follow-up drill holes for 7,424m have been completed at Ringrose to date. Four of these completed drill holes were surveyed with downhole electromagnetic ("EM") in November 2023, identifying several new conductive zones. Assay results from eleven of these holes, and results from the EM survey were previously reported in the announcements of the Company on 5July 2023, 27 February 2024, and 24 April 2024.

A plan view of the drill hole collar locations for the Ringrose infill and extension drill programs currently being drilled is shown. Additional significant Sn assay results now received from the ongoing follow-up drilling include: S1686:87.0m at 0. 65% Sn from 204m including; 7.5m at 1.,13% Sn from 253. 5.3m at 0.,52% Sn from 268.

9m;. 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. 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. Four of the planned drill holes (for 1,550m) will test along the northern extension of Ringrose mineralisation, recently intersected by S1696, and supported by modelled EM conductor orientations.
