Copper production and Metallurgical Test Results
Tartana Minerals Limited (ASX: TAT) (the Company), is pleased to announce it had achieved a strong quarter with higher production levels providing revenue in excess of A$1 million for the quarter. Production has continued during October with the production of more than 135 tonnes and we are targeting at least two shipments by month end.
Highlights:
- Sales revenue increasing: cash receipts of US$725K (A$1,039k) on sales of 295 tonnes of copper sulphate pentahydrate during the quarter.
- Tartana D15 assays confirm board zones of copper mineralisation including 76 m @ 0.60% Cu, 178 m @ 0.40% Cu or 221 m @ 0.35% Cu, - all from 31 m depth downhole.
- Excellent flotation copper recoveries (89%) from whole ore to saleable copper concentrate grading 21 % w/w Cu when testing a sample that was below the resource grade average.
- Bulk sample ore sorting results indicate that using this process will result in a 72% grade increase and recover 71% of the contained copper.
- New EPM 29119 application (Caldera Rim) east of Tartana mine site and complementing the recent Bottle Bird application (EPM 29067) near the Company’s Nightflower Silver project.
- Potential merger with Queensland Strategic Metals Pty Ltd to provide exploration tenure with exposure to critical and strategic metals (tin, tungsten, antimony) including two new copper projects.
Metallurgical drillhole D15 assays and metallurgical testwork results provide a positive outlook for development of the Tartana open pit. The broad zones of copper mineralisation provides an opportunity for mine planning to incorporate a low strip ratio with the mineralisation also exhibiting high recoveries to a concentrate. Portions of the resource (e.g. lower grade portions) or the total resource can be upgraded through Tomra ore sorting.
With the positive results the Company is completing a Scoping Study incorporating options to potentially use nearby plants and/or develop a large scale plant at the Tartana mine site and which is separate from the existing copper sulphate pentahydrate production facility.
Our exploration activities are progressing as we establish a significant presence in Far North Queensland. We have recently lodged two new EPM applications (Bottle Bird and Caldera) in areas east of Tartana and which are The Company has proposed a merger with Queensland Strategic Metals Pty Ltd which requires shareholder approval. This entity has portfolio of exploration tenements covering tin, tungsten, antimony and copper prospects which will complement Tartana Mineral’s existing exploration portfolio. In particular, it holds a group of tenements on the southern part of this caldera chain which covers the tin fields including areas which have been held tightly for decades. These tenements abut Tartana Mineral’s own Emuford application, and which provides the Company with a dominant position in this prospective region.
A key prospect is Daisy Bell which rises above the surrounding plain and hosts tin, tungsten and copper mineralisation which appears continuous along strike for more than one kilometre. Elsewhere, the Ortona project south of Georgetown has high grade copper at surface in a series of parallel veins with nickel and cobalt mineralisation present in some of the more easterly veins (see ASX release dated 18 October 2024).
