- VRX Silica (VRX) updates the mineral resource estimate (MRE) and ore reserve for its Arrowsmith North silica sand project in Western Australia
- The MRE now reads 768 million tonnes at 98 per cent silicon dioxide and was based on data from 130 close-spaced holes drilled to increase the resource confidence
- The ore reserve contains 221 million tonnes with 9.2 million tonnes in the proved category and 211.8 million tonnes in the probable category
- Cube Consulting was engaged to complete work for the ore reserve which consisted of importing and reconciling the supplied mineral resource block model

VRX Silica (VRX) has updated the mineral resource estimate (MRE) and ore reserve for its Arrowsmith North silica sand project in Western Australia.
The MRE now reads 768 million tonnes at 98 per cent silicon dioxide which includes a measured resource of 10 million tonnes at 95.9 per cent silicon dioxide.
The update was based on data from an additional 130 close-spaced holes drilled to increase the resource confidence in the initial mining years and produce a bulk sample for pilot scale metallurgical testwork.
The ore reserve contains 221 million tonnes with 9.2 million tonnes in the proved category and 211.8 million tonnes in the probable category.
VRX engaged Cube Consulting to complete mining engineering work for the ore reserve which consisted of importing and reconciling the supplied mineral resource block model and defining mining boundaries.
“This updated mineral resource and reserve is a culmination of significant metallurgical testwork and evaluation of the resource to determine the premium products we can produce,” Managing Director Bruce Maluish said.
“These products include sought after foundry sand as well as glassmaking sand suitable for flat glass, including automobile glass and also container glass.
“We have despatched large samples to a number of foundry and glassmaking companies in Korea, Japan and Taiwan for evaluation and subsequent discussions for offtake.”
Shares in VRX were up 3.45 per cent and trading at 15 cents at 11:58 am AEDT.
