Nightflower Silver Project

The Nightflower project is located 40 km north of Chillagoe in Far North Queensland and the project covers a substantial part of the northern Featherbed Volcanic Group and the underlying and surrounding Hodgkinson Formation. The project was acquired in 2022.

The mineralisation is represented by a narrow high-grade silver-lead-zinc lode which follows defined structure over several kilometres. Most historical work has focused on the Digger Lode which represents one section of the structure and where widths can extend to several metres.
Further south along the structure is the Terrace Prospect which is also identified from an historical IP survey (Axiom Mining ASX Announcement 1 July 2008) .

Tartana Minerals upgraded its Nightflower Exploration Target after reviewing its earlier estimation in light of the recent increases in the antimony price. A recalculation of the grade estimates highlighted that the earlier grade range estimate had been underestimated as reported to the ASX on 6 June 2022.

Nightflower is a high-grade silver – lead deposit with also previously overlooked significant antimony credits. 

In mid-August China, the world’s largest producer of Antimony – producing 83,000 t in 2023 (USGS) - accounting for 48% of the world’s supply, will be restricting Antimony exports from 21 September 2024. Consequently, the antimony price has significantly increased and is currently trading at US$24,500/tonne (Argus Metals, Antimony ingot min 99.65% fob China).

The revised Exploration Target is summarised below as reported on the 6 September 2024.

Note: The Exploration Target is conceptual in nature only and there is no guarantee that further exploration will define a resource. (See ASX announcement dated 6 September 2024).

The company is planning a drill programme to upgrade the Exploration Target to resource status.
