BBX Minerals (ASX:BBX) has provided initial results from biobleaching test work conducted with EcoBiome Metals, using a surface bulk sample of mafic intrusive from the Ema project.

The goal of the bioleaching was to demonstrate how BBX?s complex mineralisation responds to EcoBiome?s patent pending microbial technology.

BBX says samples were assayed for gold, platinum, palladium, iridium and rhodium, and showed a significant increase in reported precious metals following biobleaching.

The company?s share price is up 30% in afternoon trading.
