Brazil Potash Corp. (GRO) announced initial test results for its artificial-intelligence-powered X-ray transmission ore sorting system. In early trials on a small sample, the process upgraded material with roughly 13% potassium chloride content to approximately 27%, while discarding about 20% of lower-grade material with waste levels between 1% and 2%. Shares of the company rose 0.93% to $2.16 following the update.

The sorting technique applies to about 40% to 55% of ore sized above 8 millimeters. By rejecting waste prior to full processing, pre-concentration could boost plant throughput, reduce operating expenses, and improve overall recovery at the company's Autazes project before commercial operations begin.

Because these findings stem from a limited and non-representative sample, high execution risks remain. Investors should monitor upcoming larger-scale testing programs along with engineering and economic feasibility studies to confirm whether these sorting benefits hold at full production scale.

## Key points

- Initial AI ore sorting tests upgraded sample material from roughly 13% potassium chloride to 27%.
- The pre-processing method rejected about 20% of lower-grade material with discard grades of 1% to 2%.
- Between 40% and 55% of ore sized over 8 millimeters is suitable for the XRT sorting technology.
- Results are preliminary and based on a small sample that is not yet representative of full-scale output.

## Questions and answers

### What were Brazil Potash Corp.'s AI ore sorting test results?

In preliminary tests on a small sample, AI-powered XRT sorting upgraded ore from about 13% potassium chloride to roughly 27%, rejecting about 20% of lower-grade waste containing 1% to 2% potassium chloride.

### What percentage of ore can be sorted with XRT technology at Brazil Potash?

Between 40% and 55% of ore sized greater than roughly 8 millimeters is suitable for XRT sorting.

### Are Brazil Potash's AI ore sorting results representative of full production?

No. The results are preliminary and taken from a small sample. Larger testing programs and economic studies are required to verify results for full-scale commercial output.
