Tartana finds high-grade copper and gold at four Queensland prospects
Tartana Minerals found high-grade copper and gold in surface samples at four prospects in the OK-Bellevue area of Far North Queensland.
The strongest results included 17.1% copper at OK Blocks, 12.0 grams of gold per tonne at Hobblechain and more than 10% copper in two Windmill samples.
The company also sampled historical waste piles at OK Dumps, where results included 8.29% and 3.61% copper, and plans metallurgical work on the material.
The findings will help Tartana rank targets for its first scout drilling, alongside mapping, geophysical work and historical records.
The area has a long mining history, but the new samples do not show how much metal may lie underground.
Older drill results beneath former mines offer some depth context, but they have not been independently verified and do not prove the new prospects connect to those deposits.
Tartana says it will assess the evidence before choosing where to drill, and has land-access arrangements in place to continue its work.
Tartana Minerals reported high-grade copper and gold assays from four prospects at OK-Bellevue in Far North Queensland.
The strongest results included 17.1% copper at OK Blocks and 12.0 grams per tonne of gold at Hobblechain.
Two Windmill samples returned more than 10% copper, while samples of historical dump material at OK Dumps returned 8.29% and 3.61% copper.
The company said the results would help it rank targets for scout drilling.
It plans further mapping, sampling and review of geophysical and historical data before choosing its first scout holes.
- Who
- Tartana Minerals, an exploration company.
- What
- It reported high-grade copper and gold assays from four prospects and is assessing targets for scout drilling.
- When
- The results were reported on 15 October 2026.
- Where
- The OK-Bellevue project in Far North Queensland, Australia.
- Why
- To re-evaluate the historical mining district and help prioritise targets for scout drilling.
This story does not have two clearly opposing sides.
Mining began in the Chillagoe district, according to Geological Survey of Queensland research.
Tartana reported assay results from 11 selective surface samples collected across four OK-Bellevue prospects.
Tartana plans further mapping and sampling, assessment of geophysical targets and review of historical data before selecting scout holes.

- Project
- OK-Bellevue, Far North Queensland
- Samples
- 11 selective surface samples from four prospects

What people are saying
Results of 17.1% copper at OK Blocks, 12.0 g/t gold at Hobblechain and more than 10% copper in two samples at Windmill are a very encouraging return from a focused field program.
Our job now is to turn those results into a sensible drill plan.
