Sarytogan Graphite achieves up to 97.7% yield of battery‑grade graphite

The company’s processing pathway, which it calls an “inverted flowsheet”, involves purifying the graphite before spheroidization. This is a clever piece of process design, as it means any graphite particles that don’t meet the size or shape specifications during spheroidization can still be sold as a premium ultra-high purity product, rather than a lower-value concentrate.

All this is happening against the backdrop of Sarytogan’s colossal mineral resource, which stands at 225 million tonnes grading a remarkably high 29.2 per cent total graphitic carbon. The deposit’s scale and grade have not gone unnoticed on the world stage, with the project having been designated a Strategic Project under the European Union’s Critical Raw Materials Act, highlighting its potential as a vital future supplier to Europe.

With an upstream definitive feasibility study for the mine and initial processing plant now in its final stages and due for release next quarter, the company appears to be methodically piecing together a mine-to-market plan.

Meanwhile, 25 kilometres away, Sarytogan’s Baynazar copper project recently delivered the goods with a 229 metre copper hit grading 0.14 per cent copper from surface to end of hole. The impressive hit came from the Ilskan prospect and confirms the presence of a copper porphyry-style mineralised system. The company is now eagerly awaiting results from two other diamond drill holes at Ilskan.

The latest downstream results provide strong proof of concept that Sarytogan’s world-class deposit can be transformed into a world-class battery product. As the company moves to test its material in commercial-style batteries, it looks as though many eyes in the EV supply chain might be watching closely.
