September is here — and so is the Q4 countdown. ⏳

For mining and exploration companies across Africa, the final quarter is the most critical of the year. Deadlines are real. Year-end targets don't move. And testwork results that aren't in hand by December can push project milestones into the following year.

If you have testwork that needs to be completed before the industry slows down, now is the time to get it scheduled.

At Peacocke & Simpson, we are ready to support your Q4 program — from fire assay and GRG testwork to kinetic leaching, flotation, and full flowsheet development. ISO certified. In-house. Harare-based. Africa-focused.

Don't let the year end without the results your project needs. 💛

Peacocke & Simpson was founded in 1985 with a simple mission: provide mining companies in Africa with testwork that is relevant, practical, and meaningful.

That mission hasn't changed. Our capability has.

Expanded services. World-class equipment. ISO certification. A track record that spans the continent.

From Zimbabwe to Burkina Faso. From gold to lithium. From first sample to first gold.

We're the testwork partner Africa's miners trust.

Every ore body is different. Every project has unique requirements.

Rather than guessing what testwork program is right for you, let's have a conversation.

Our team will help you scope the testwork that gives you maximum value for your budget and timeline — whether you're at exploration stage, pre-feasibility, or optimizing an existing operation.

No obligation. Just good advice from people who've done this for 40 years.

There is no better proof of work than seeing your equipment in the ground and producing. 🇿🇼

These are shots from one of our Knelson Concentrator installations at one of Zimbabwe's leading gold mining operations — commissioned and optimised by the Peacocke & Simpson team.

As authorised FLSmidth/Knelson representatives in the region, we don't just supply the equipment. We handle the full journey — from testwork to confirm gravity concentration is justified, to right-sizing the unit for your specific ore and flow rate, to on-site commissioning support to ensure you achieve first gold.

Every installation backed by 40 years of gravity gold experience. Every result backed by our ISO certified quality system.

If you are designing or upgrading a gravity circuit, let's talk. 💛

The most sophisticated testwork program in the world is worthless if it starts with a poor sample.

At Peacocke & Simpson, our sample preparation procedures follow strict protocols — careful splitting and sub-sampling — to ensure what we test truly represents your ore body.

Results you can trust start with samples you can trust.

Ask us about our sample preparation standards before you submit.
We have the experience. Let's talk about your deposit.

Africa hosts over 80% of the world's known PGM reserves — platinum, palladium, rhodium, and more.

Recovering PGMs typically involves flotation to produce a sulphide concentrate, followed by smelting and refining. But PGM flotation chemistry is complex and highly ore-specific.

Getting your PGM flotation testwork right is critical to project economics.

Extended Gravity Recoverable Gold (EGRG) testing reveals additional gravity recovery potential beyond standard GRG — particularly where gold is liberated through further comminution.

For mines currently running a gravity circuit, EGRG can answer: Are you capturing everything you could be? Would a circuit upgrade pay for itself?

We set the global standard for EGRG. Let us test yours.

For refractory ores where gold is locked in sulphide minerals, ultra-fine grinding (UFG) can dramatically improve leach recovery.

By grinding to very fine sizes (P80 < 20 microns), mineral surfaces are exposed and cyanide can access previously locked gold.

Our UFG testwork program determines:
• Optimal grind size for maximum recovery improvement
• Energy cost implications
• Whether UFG is justified for your ore

The numbers often surprise clients.
