Testwork could also allow for the upgrade of the current probable ore reserves to proven.

Infill drilling at T3 has been ongoing since January, with 49 of the planned 60 holes completed and the remainder due by the end of the June quarter.

The companies previously released the assay results of the first 11 holes and have now received the following 25.

Highlights from these holes included 21m at 1.5% copper and 30g/t silver from 118m, including 10m at 2% copper and 44g/t silver from 118m; 26m at 1.8% copper and 25g/t silver from 119m, including 6.4m at 4.6% copper and 75g/t silver from 121m; and 16.5m at 1.8% copper and 18g/t silver from 84m.

Other highlights were 60m at 1% copper and 13g/t silver from 78m; 11.4m at 2.1% copper and 16g/t silver from 75m; 1.9m at 41.4% copper and 25g/t silver from 82m, including 4.4m at 2.6% copper and 141g/t silver from 87m; 16m at 1.9% copper and 26g/t silver from 117m; and 20.5m at 2.2% copper and 44g/t silver from 106m.

MOD managing director Julian Hanna said the drill programme had continued to intersect wide, high-grade vein-hosted mineralisation, while also providing more clarity around the up-dip extent of mineralisation within the first two pit shell stages planned.

Metal Tiger CEO Michael McNeilly added the second batch of results continued to support the expectation that a significant portion of the mineral resource could be upgraded to the measured category, which helped to "further de-risk the attractive mining proposition".

Metal Tiger's shares (AIM:MTR) rose 14.13% on the news to 1.31p (US1.69c), while the dual-listed MOD's shares (ASX:MOD) dropped 1.43% in Australia trading to A34c (US24c).
