Right Resources (ASX:RRE) has confirmed high-grade tungsten in a maiden metallurgical testwork program at the Blue prospect within the Tumbarumba region of New South Wales.

Testing has been undertaken on a surface bulk sample containing visible scheelite and wolframite mineralisation was collected from outcrop and subcrop exposures at the Blue prospect for metallurgical evaluation.
Approximately 32 kg of this material was received by Nagrom Laboratories in Perth for the company’s maiden metallurgical testwork program.
The composite metallurgical sample has returned a head assay of 0.48% tungsten trioxide (WO3).
MD, Graham Howard, said this result establishes the feed grade for the company’s initial metallurgical testwork program and provides the basis for assessing the response of the tungsten mineralisation to beneficiation and recovery processes.
“The composite head grade of 0.48% WO3 provides an encouraging starting point for the company’s maiden metallurgical testwork program at Blue,” he said.
“The focus now is on understanding how the tungsten mineralisation responds to beneficiation and determining the extent to which the feed can be upgraded and the tungsten recovery that can be achieved.
“The supporting mineralogical and size-by-assay studies will also help us better understand the characteristics of the mineralisation and inform the next stages of the program.
“This is an important step in advancing our technical understanding of the Blue Prospect and will inform future project evaluation and testwork programs.”
The current testwork program is focused on determining whether the tungsten-bearing minerals can be effectively upgraded from the composite feed and, if so, the achievable concentrate grade and tungsten recovery.
Supporting size-by-assay and mineralogical studies are also underway to determine the distribution of tungsten across different particle-size fractions and to better understand the occurrence, liberation and mineral associations of scheelite, wolframite and other relevant minerals within the sample.
Two separate sub-samples collected from the bulk metallurgical sample returned tungsten grades of 0.77% WO3 and 0.80% WO3. These results confirm the presence of higher-grade tungsten mineralisation within portions of the sampled material, but should not be considered representative of the overall composite metallurgical sample.
Results from the current program are expected to provide important information on the metallurgical characteristics of the Blue prospect mineralisation and assist in guiding subsequent exploration, project evaluation and future metallurgical testwork.
