Highlights

  • Sky Metals (ASX:SKY) advances bulk sampling at the Tallebung Tin Project in New South Wales

  • Ore sorting delivers significant grade improvements and high recovery results

  • Additional upgrades achieved for silver and tungsten alongside tin concentrate work

Sky Metals (ASX:SKY), a company listed on the asx 200, has reported advancements at its flagship Tallebung Tin Project located in central New South Wales. The company outlined strong results from ore sorting test work that reinforced the progression of bulk sample processing.

Ore Sorting Results at Tallebung

The Tallebung Tin Project has shown remarkable results through the application of ore sorting technology. Using a staged circuit, the company has delivered improvements in grade and recovery from large-scale samples. The outcomes confirmed the scalability of the process and indicated consistency with prior smaller-scale studies.

Large bulk samples were processed in an initial stage before being upgraded in a secondary step, leading to refined tin output. This process resulted in a significant uplift in overall grade quality, highlighting the effectiveness of ore sorting in enhancing concentrate preparation from bulk material.

Processing Work at ALS Facilities

Material from the Tallebung site has been undergoing further processing at facilities in Perth. Dense medium separation trials are underway with the intention of producing a saleable concentrate. The work includes pilot-scale gravity separation in Burnie designed to prepare tin concentrate suitable for marketing discussions.

The company highlighted that large discrete cassiterite grains within shallow veins across the project are well suited for ore sorting, enabling efficiency even from challenging zones. This geological characteristic continues to underpin positive advancements in processing outcomes.

Silver and Tungsten Recovery Improvements

In addition to tin, the project also recorded gains in the recovery of other commodities. Silver showed marked upgrades from baseline levels, and tungsten recoveries improved alongside tin results. These complementary gains add further scope for value creation within the broader mineral system at Tallebung.

The ore sorting strategy not only delivered enhanced tin grades but also confirmed consistent recovery improvements across associated metals. These developments highlight the role of advanced technology in optimising multi-element outcomes from bulk mining samples.

Commodity Market Relevance

Tin remains a critical metal for industrial use, particularly in electronics and packaging applications due to its corrosion resistance and adaptability. Silver and tungsten also hold significance in industrial manufacturing, reinforcing the multi-metal relevance of the Tallebung project outcomes.

The advancements at the Tallebung Tin Project position Sky Metals (ASX:SKY) within the broader framework of Australian resource development, contributing to the strength of mining activity represented on the asx indices. Ongoing work continues to focus on refining concentrate preparation and advancing project scalability.
