Established in 1985, Peacocke & Simpson has vast experience in the minerals processing industry, providing RELEVANT and MEANINGFUL mineral testwork on nearly all hydrometallurgical processes for nearly all minerals. Based in mineral-rich yet underdeveloped and logistically challenging Africa, we understand that our clients require practical solutions and results, as opposed to laboratory print-outs and irrelevant research.

Our Clients

DRA appreciates the generous expertise of Pete Simpson of P&S in gravity gold concentration and leach extraction and his valued commissioning contribution towards achieving first gold on these projects.

Glenn Bezuidenhout, Process Director, DRA Global

During a unique, short-term high grade period we produced 3,000 oz. of gold in a 24hr operating shift from three XD 48 Knelson Concentrators. They are worth their weight in gold.

Marnu Lombaard, Metallurgical Engineer, AngloGold

We have been proudly associated with Peacocke & Simpson since 1987. Over the years, they have successfully developed and executed many of the most advanced and metallurgically challenging gravity-based test programs on behalf of their clients. There is no doubt that many of these clients have realized significant positive financial benefits as a result of their practical and innovative approach.

Doug Corsan, Vice-President, Knelson Concentrators

Thanks to P&S for a job well done on the Singida metallurgical testwork program. Shanta can now move forward on the BFS with a great deal of confidence, knowing that the gravity and leach test work have been completed in both a comprehensive and professional manner.

Wally Channon, Technical Manager, Shanta Gold
