Resource scale
More than 90 million metric tonnes of government-approved and assessed quartz resource. The reported approved production exceeds 4 million tonnes per annum.
Read the assessed tonnage and approved production figures on their respective bases. Ask the commercial team for current availability of the processed fraction you need.
Mudigubba lease
More than 60% of the assessed material is reported as A and M grade quartz.
The percentage describes the reported mix at lease level. For procurement decisions, use the available chemistry and sizing data for the proposed product or sample.
Chakrayapet lease
Approximately 90% is reported as A and M grade quartz. The source brief reports a silica range of 98.5–99.5% for these grades.
Compare the reported grade mix with Mudigubba in the lease overview. Qualification still depends on the end use and agreed product limits.
Supply planning
Resource and approved production figures describe the deposit and permitted production. Confirm finished-product volumes and schedules directly with the commercial team.
For a supply discussion, share the product form, required fraction, volume and delivery window. This helps connect the resource profile to a specific commercial enquiry.
