Baynazar Drilling Defines 0.5% Copper Zone Over 600m Diameter

Mining By Maxwell Dee 3 min read

Sarytogan Graphite Limited has revealed a significant copper anomaly at its Baynazar project in Kazakhstan, outlining a 600-metre-wide zone with up to 0.5% copper. The company plans deeper drilling to explore this promising copper porphyry system, pending funding.

  • 130 shallow KGK drill holes define a 600m diameter copper anomaly up to 0.5% Cu
  • Polymetallic signature includes silver, molybdenum, antimony, gold, cobalt, nickel, lead, and zinc
  • Alteration patterns consistent with copper porphyry mineralisation
  • Next phase – 200-500m diamond drilling contingent on securing dedicated funding
  • Ongoing development of flagship Sarytogan Graphite Deposit continues in parallel

Exploration Breakthrough at Baynazar

Sarytogan Graphite Limited (ASX – SGA) has announced encouraging results from its recent shallow KGK drilling program at the Baynazar copper exploration project in Kazakhstan. The program, comprising 130 drill holes averaging 12 metres in depth, has delineated a substantial copper bedrock anomaly measuring approximately 600 metres in diameter with copper grades reaching as high as 0.5%.

This discovery is particularly notable given the polymetallic nature of the anomaly. Alongside copper, elevated levels of silver, molybdenum, and antimony were detected in the core, while gold, cobalt, nickel, lead, and zinc anomalies were identified on the periphery. Such a geochemical signature aligns well with the characteristics of a copper porphyry system, a type of deposit known for its large-scale mineralisation potential.

Geological Context and Historical Insights

The Baynazar project lies within the Central Asian Orogenic Belt, a prolific mineral province spanning Kazakhstan and neighbouring regions. The Ilkin Prospect, where drilling was focused, features Devonian sedimentary sequences intruded by granite-diorite bodies, creating favourable conditions for porphyry-style mineralisation. Alteration mapping revealed typical zonation patterns, potassic and sericitic alterations near the intrusive core, with propylitic alteration forming an outer shell, further supporting the porphyry model.

Historical Soviet-era drilling at Ilkin encountered mineralised diorites with copper grades increasing with depth, though the reliability of these older results remains unverified. Sarytogan’s recent shallow drilling has refined these earlier indications by sampling fresh bedrock beneath weathered cover, providing a clearer picture of the mineralisation distribution.

Next Steps and Funding Considerations

While the shallow drilling has successfully outlined the anomaly, Sarytogan emphasises that the next critical phase involves deeper diamond drilling to test the system at depths of 200 to 500 metres. This step is essential to confirm the deposit’s size, grade continuity, and economic potential. However, this program is contingent upon securing dedicated funding for copper exploration, as the company’s primary focus remains on advancing its flagship Sarytogan Graphite Deposit.

Managing Director Sean Gregory expressed optimism about the findings, noting that the results exceeded expectations and that the geological and geochemical data strongly suggest a copper porphyry system. The company’s strategic positioning in Kazakhstan, a jurisdiction known for low-cost copper production, adds to the project’s appeal.

Strategic Importance and Broader Implications

Beyond copper, Sarytogan continues to develop its graphite assets, which are recognised under the European Union’s Critical Raw Materials Act as strategically important for battery and industrial applications. The dual focus on graphite and copper exploration positions the company to potentially benefit from growing demand for critical raw materials in energy transition technologies.

Overall, the Baynazar results mark a significant milestone for Sarytogan, highlighting the potential to expand its resource base and diversify its portfolio. The coming months will be pivotal as the company seeks funding and plans deeper drilling to unlock the full value of the Baynazar copper system.

Bottom Line?

Sarytogan’s Baynazar copper anomaly sets the stage for a deeper drill campaign that could reshape its resource outlook; funding will be the key catalyst.

Questions in the middle?

  • Will Sarytogan secure the necessary funding to commence deep diamond drilling at Baynazar?
  • How might the new copper discovery impact the company’s overall valuation and strategic focus?
  • What are the timelines and expected costs associated with verifying and expanding the copper resource?
