European Metals Holdings Limited (ASX: EMH) has completed initial metallurgical testing at the Cinovec Tin Project in the Czech Republic (Figure 1).
Figure 1. Location of Cinovec Tin Project
Independent consultants ALS conducted the testwork and highlights include:
- Potential overall tin recovery of 80%
- Gravity concentrate of 13.9% Sn
- Preliminary assessments indicate the tin grade can be increased by processing through a gravity dressing circuit to greater than 50% Sn
Drill core weighing approximately 12kg was submitted to the ALS metallurgical facility in Burnie, Tasmania for preparation, mineralogy and gravity separation assessment. The sample is a composite of 16 individual segments weighing between 0.47kg and 0.75kg.
A six cycle gravity locked cycle test was performed resulting in a tin grade concentrate of 13.9% with potential improvement in tin concentrate grade of above 50% Sn.
Mineralogical assessment shows that 95% of cassiterite in the plus 20 micron fraction occurs as free grains and it is estimated that up to 50% of the -30/+7 micron material could be recovered by floatation boosting overall recovery of tin to 80%. Further recovery testwork will be concluded at the next metallurgical testwork campaign.
Metallurgical testing to assess the suitability of technology for extraction of lithium from zinnwaldite is underway with initial leach test results due in the near future. The lithium resource for Cinovec is being updated and expected to be complete in the near future.
The Scoping Study is on track for completion before the end of the March 2015 quarter.
