Viking Mines (ASX:VKA) has confirmed that historical processing recovered the majority of tungsten from mined material at its Linka Tungsten Project in Nevada, US, with tailings sampling returning low residual grades.

The 52-sample program returned a thickness-weighted average of 0.03% tungsten trioxide (WO3), with a maximum of 0.15%. The company says the results provide positive metallurgical context for Linka’s primary mineralisation and support confidence in the project’s processing characteristics.

“The tailings program has delivered a useful and positive result,” Managing Director Julian Woodcock says.

“Very little tungsten appears to have been left behind in the historical tailings dam, which supports the view that the historical operation recovered tungsten extremely efficiently from Linka ore.

“That is a constructive read-through as we prepare for maiden drilling. Linka now has low residual tailings grades, a quality 56.9% WO3 concentrate from recent test work at 76% recovery, and drilling about to commence.”
