The board of directors of Greentech Technology International Limited provided an update on the exploration drilling results at 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"). Recent surface exploration drilling has intersected significant mineralisation during a program to test down hole electromagnetic (DHEM) conductors defined during a 2019 DHEM survey of historic drill holes located north and south of known mineralisation at the Renison Mine.

Drill hole S1671 was previously drilled to test DHEM conductors south of the existing mine development and intersected significant mineralisation - 26.93m down hole width @ 4.57% Sn from 225.07m. The S1671 intersection was followed up with a further five diamond drill holes. Three of these drill holes have returned significant assay results.

Two drill holes S1682 and S1678 are still pending assay results. S1675: 11.5m (ETW) @ 1.27% Sn from 173.6m. S1679: 8m (ETW) at 1.49% Sn from 136.1m.

S1681: 3m (ETW) @1.21% Sn from 218.9m. Mineralisation is located about 750m south of existing development and occurs over approximately 200m down dip and 250m strike length. Mineralisation is open to the north, south and at depth.

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 was planned to test the ranked conductors and assess the potential for DHEM to detect tin bearing sulphide mineralisation.

This program was completed during 2022. A subsequent phase 2 program commenced in August 2022 to test further DHEM conductors and S1671 was the second of six planned holes in this program. Following the reported S1671 significant intersection of 26.93m down hole width @ 4.57% Sn from 225.07m, five additional follow-up drill holes were completed to test the extent of this mineralised zone.
