140m Trench at Ilkin Yields 0.09% Copper, Drilling Plans Underway

Exploration Update at Baynazar

Sarytogan Graphite Limited has provided a significant update on its copper exploration efforts at the Baynazar project in Kazakhstan. The company’s recent trenching program at the Ilkin prospect has yielded promising copper assay results, with a 140-metre trench returning an average grade of 0.09% copper. Notably, within this interval, there are higher-grade sections including 86 metres at 0.10% copper and an 8-metre stretch at 0.20% copper.

This trenching was conducted in weathered diorite rock and is complemented by extensive soil sampling and a high-resolution aeromagnetic survey that identified a circular magnetic anomaly coincident with the copper anomalism. These combined geophysical and geochemical indicators enhance confidence that the mineralisation extends into fresh bedrock, making Ilkin a compelling drill target.

Historical Context and Geological Setting

The Baynazar project sits within the Central Asian Orogenic Belt, a prolific mineralised region known for copper porphyry deposits. Historical drilling from the 20th century at Ilkin encountered mineralised diorite with copper grades increasing with depth, though the reliability of these older results remains uncertain. Sarytogan’s recent work aims to verify and build upon this legacy data.

The geological setting includes a cluster of volcanic calderas, with the Ilkin prospect located near a significant circular aeromagnetic feature. This structural context is favourable for copper porphyry mineralisation, similar to other successful deposits in Kazakhstan.

Next Steps and Funding Considerations

With the trench results confirming substantial copper anomalism in weathered rock, Sarytogan has declared the Ilkin prospect drill ready. The company plans to initiate KGK drilling, a water coring technique capable of penetrating transported cover and weathered zones to sample fresh bedrock. This initial drilling will help define targets for subsequent deeper diamond drilling.

However, the execution of this drilling program is currently subject to funding availability. Recent investment from the European Bank for Reconstruction and Development is being prioritised towards advancing Sarytogan’s graphite project, which remains the company’s flagship asset. The copper exploration program’s progress will depend on securing dedicated funding to unlock the potential at Baynazar.

Strategic Implications

Sarytogan’s dual focus on graphite and copper exploration positions it uniquely within Kazakhstan’s mining sector. The graphite deposit is recognised as a strategic resource under the EU’s Critical Raw Materials Act, while the copper project taps into a region known for low-cost, high-quality copper production. Success at Ilkin could diversify the company’s portfolio and enhance its appeal to investors seeking exposure to critical battery materials and base metals.
