Nova Silica Sand project sighter test work
produced high grade silica sand to 99.31% SiO2
suitable for glass manufacture and foundry
applications
• Sighter metallurgical tests produced high quality silica sand to
99.31% SiO2
• Shallow drilling program of 44 air core dill holes to develop
six metallurgical sighter samples from white zones
• Analysis of sand product shows suitability for use in glass
manufacturing and foundry applications
• XRD mineralogy of the sand was exclusively silica and the
sand sizing at AFS 47- 61 is suitable for foundry applications
including the casting of electric vehicle motor parts
• Further testing to determine if silica flour is present in the
finer (>45µm to the <75µm) fraction can be captured
• Silica flour is a high value product with applications as a filler
or wellhead cement additive
• Analysis of remaining samples has commenced and will be
used in the determination of a JORC compliant resource
• Market pricing for:
o Glassmaking silica sand - US$35-$53 per dmt
o Foundry silica sand - US$38-$53 per dmt
• The silica flour market for fillers and wellhead cement
additives is highly specialised and pricing can reach US$140-
$150 per dmt.
