Drilling at Mt Carlton confirms gold-silver-copper grade

Two rigs were employed to infill and extend the known limits of the gold-silver-copper mineralised systems across both deposits

Assays from ongoing resource definition and exploration drilling at the Telstra Hill and Mt Carlton United deposits within Navarre Minerals’ recently-acquired Mt Carlton operation in North Queensland have confirmed strong grade and geological continuity.

Results from an additional six reverse circulation and 20 diamond core holes for 2,458 metres of drilling across both deposits returned “outstanding” gold-silver-copper intercepts to reinforce the shallow, high-grade mineralisation and highlight the prospectivity of the broader project area.

Two rigs were employed to infill and extend the known limits of the gold-silver-copper mineralised systems across both deposits.

Telstra Hill is located approximately 1km northwest of the Mt Carlton processing facility and is interpreted to be an intermediate sulphidation epithermal gold-copper-silver system hosted within the same rhyodacite volcanic package as Navarre’s producing V2 deposit.

Nine holes drilled for 1,597m confirmed Telstra Hill’s potential to provide supplemental mill feed at Mt Carlton.

Highlights included 6.2m at 13.5 grams per tonne gold and 1.5g/t silver from 17.8m; 4m at 2.4g/t gold and 3.2g/t silver from 38m; and 1m at 5.2g/t gold and 16.4g/t silver from 14m.

Mt Carlton United is an intermediate sulphidation epithermal system which extends in an east-west orientation and has a similar characteristic to V2 with the mineralisation structurally controlled and hosted in the same rhyodacite volcanic unit.

Navarre anticipates the drilling results will inform an updated resource estimate for both deposits; this is expected to be published by mid-2023.

Navarre managing director Ian Holland said the latest results point to a complementary resource for the Mt Carlton operation.

These high-grade results from Mt Carlton United and Telstra Hill continue to demonstrate the project development opportunities present on the Mt Carlton mine lease, he said.

He said: It is pleasing that our ongoing investment in exploration and resource drilling is delivering on our strategy of defining new satellite mineral deposits within short trucking distance to the mine (and) we also see significant potential to expand our satellite mineral inventory with key targets including Crush Creek and other regional prospects.
