Yellow Rock Resources confirms high vanadium quality at Gabanintha
Yellow Rock Resources (ASX:YRR) has widened the scope of development options at its Gabanintha vanadium project in Western Australia with positive mineralogical testwork indicating favourable processing characteristics.
Results from the study indicated that magnetic separation techniques will be applicable for both high-grade and low-grade ores at the project since magnetite gabbro in the resource contains high amounts of vanadium.
Vanadium grades in magnetite were as high as 3.1% V2O5, compared to the sample head grade of 0.8% V2O5.
Mineral chemistry suggests that there is little change in vanadium grade within the massive mineralised layer from fresh to oxide in the profile. This confirms consistent value throughout the pit profile and the ubiquitous stability and presence of vanadium within the magnetite or martite.
These findings suggest that magnetic separation of low-grade ores should be productive and yield a good vanadium grade.
All results and findings are being used in Gabanintha's ongoing metallurgical assessment and will form key components to final process design in 2016.
This plant design work will take place as part of a feasibility study.
