Digging With DNA: Soil’s “Biological Fingerprints” Point to Hidden Diamonds
Researchers have pioneered a method to detect buried kimberlite, a diamond-associated rock, by studying microbial DNA in surface soil. This offers a non-invasive way to identify minerals deep underground, proving more precise than traditional geochemical analysis. The technique, with broader applications in mineral exploration, could redefine the future of the mining sector.

Digging With DNA: Soil’s “Biological Fingerprints” Point to Hidden Diamonds

DNA sequencing methods can also assist in identifying minerals crucial for the transition to green energy. Researchers have identified buried kimberlite, the rocky home of diamonds, by testing the DNA of microbes in the surface soil. These ‘biological fingerprints’ can reveal what minerals are b
