Drilling by Robust Resources on Romang Island has returned the strongest precious metal and polymetallic intersection to date at the Lakuwahi project. The hole revealed broad intersections of shallow high grade gold, silver and polymetallic mineralization.1

It returned 43 metres from 2 metres @ 5.18 grams/tonne gold equivalent, comprising 4.63 grams/tonne gold and 33 grams/tonne silver, and included 17 metres from 15 metres @ 9.63 grams/tonne gold equivalent, comprising 9.08 grams/tonne gold and 33 grams/tonne silver. It also returned 76 metres from 37 metres @ 1.47% copper equivalent, comprising 0.29 grams/tonne gold, 16 grams/tonne silver, 0.27% copper, 1.77% lead and 1.40% zinc, and included 17 metres from 42 metres @ 3.31% copper equivalent, comprising 0.45 grams/tonne gold, 22 grams/tonne silver, 0.91% copper, 3.85% lead and 3.07% zinc.

The combination of the grades and thicknesses of precious metals located near surface, and polymetallic sulphides intersected in this hole make it the most significant hole to be drilled on Romang Island to date.

The hole was extended to greater depth and was inclined to the north, which is opposite to all previous drill holes in this section. Drilling encountered a broad zone of very strong polymetallic sulphide mineralization beneath the precious metals zone. The polymetallic zone included high grade copper mineralization assaying 2.64% copper over 6 metres.

The results from this hole and existing drilling data has led to a refinement in the geological understanding of the Lakuwahi mineralization and the recognition of flat-lying lithological controls on the formation of the crackle breccia-hosted mineralization.

Robust’s managing director Gary Lewis says, “This information is vital in the preparation of the geological and mineralization model which underpins our mineral resource estimate, a current key focus for the company.”
