Tests validate Blencowe's project's potential for producing synthetic diamonds.

Yes, testwork has confirmed that graphite from Blencowe Resources’ Orom-Cross project is suitable for synthetic diamond manufacture, achieving conversion yields above the industry benchmark for economic production outside China.

The test results were announced on February 9-10, 2026, following independent work by American Energy Technology Co. (AETC) in Chicago .

Here are the critical technical and commercial specifics validated by the testwork:

Metric	Result / Detail	Strategic Significance
Diamond Conversion Yield	53.6wt%	Exceeds the typical industry benchmark of ~50%, which AETC notes is critical for cost-competitive production outside of China .
Diamond Structure	Mono-crystalline	A higher-value structure compared to polycrystalline alternatives .
Particle Size	Average 50-60 microns; up to 350-500 microns	Demonstrates successful crystal growth suitable for industrial applications .
Key Enabler	Fine, compressible flake structure	This characteristic proved highly conducive to diamond synthesis, unlike thicker flakes found in other East African deposits .

Commercial Context:
Blencowe is pursuing this as a “non-China” value-addition pathway. The results strengthen the company’s funding and offtake discussions by demonstrating that Orom-Cross graphite is not limited to battery applications but can also serve specialized industrial markets .

Summary: The testwork confirms the technical potential for synthetic diamond manufacture, moving the project into a phase where the company will now seek offtake opportunities in this sector.
