The Witwatersrand Basin is not just part of South Africa’s history — it is the most significant gold resource ever discovered globally.

→ Over 40,000 – 48,000 tonnes of gold mined from the basin since 1886 (Buy Gold Africa)
→ Equivalent to roughly 25% – 40% of all gold ever mined in human history (The Heritage Portal)
→ Still the largest gold resource on Earth (Minerals Council SA)

To put this into perspective:
→ Total gold ever mined globally: ~187,000+ tonnes (World Gold Council)

⸻

What remains

South Africa:
→ ~2,800 – 3,000 tonnes of proven reserves (Buy Gold Africa)

Global:
→ ~54,000 – 64,000 tonnes of economically viable reserves remaining (Live Science)

⸻

Context

South Africa once produced the majority of the world’s gold. Today, the remaining resource is deeper, more complex, and more capital-intensive — shifting the industry from scale to precision.

At Manhattan Corporation, this is where we operate:
→ Supporting efficient extraction of remaining resources
→ Enabling technically complex projects
→ Driving long-term value in mature mining environments

The era of easy gold is over.
Ex*****on is now the differentiator.

From discovery to production — faster.

At Manhattan Corporation, we understand that in mining, time is one of the most valuable resources.

That’s why we design, manufacture and deliver fast-tracked turnkey processing plants that help mining companies move rapidly from exploration and test work to operational production.

Our approach integrates every stage of project development:
* Metallurgical laboratory testing
* Process flowsheet development
* Detailed engineering and plant design
* Workshop fabrication
* Plant construction and commissioning

By combining proven metallurgical data with in-house engineering and fabrication, we reduce project timelines while maintaining the accuracy and reliability required for successful operations.

The result: processing plants designed for quick deployment and fast payback.

From greenfields exploration to fully operational processing plants, Manhattan delivers mining solutions that perform.

At Manhattan, we specialise in accelerating the journey from discovery to production — turning technical potential into operational mining assets through rapid, disciplined ex*****on.

Our teams combine decades of experience across geology, metallurgy, process engineering, and project delivery, bridging the critical gap between early-stage resource definition and fully operational processing facilities.

We support projects from evaluation through to environmentally responsible production:
* Geological assessment & exploration support
* Metallurgical testing & flowsheet development
* Process route selection & optimisation
* Modular processing plant engineering
* Mine infrastructure and rapid-deployment delivery
* Safe, compliant, high-yield operations

As an ex*****on-focused partner, we integrate geology, metallurgy, infrastructure, and processing into a single delivery pathway — enabling faster project start-up while ensuring designs are scalable and built for long-term expansion.

Our approach combines rigorous engineering thinking with practical delivery expertise, transforming technical studies into operational reality and unlocking value where it matters most.

Manhattan — bridging discovery to production.

Exploration → Metallurgy → Processing → Infrastructure → Operations

Let’s build mining projects that last.

Ever wondered why scrubber speed matters? ⚙️ In our latest blog, we break down critical speed—the key to getting the right lift, cascade, and wash action in rotary drum scrubbers.

Read More on our Blog:-

Critical speed is the theoretical RPM where particles stick to the scrubber shell instead of tumbling. Operating at 60–70% of this speed creates optimal cascading, maximising clay breakdown and washing efficiency without excess wear or energy waste. Learn how to calculate % critical speed and hit ...

Choosing the right aspect ratio can make or break a scrubber circuit.
From residence time to scrubbing intensity, the length-to-diameter (L/D) ratio determines whether your rotary drum scrubber maximizes throughput or unlocks cleaner product.

In our latest blog, we explore how different aspect ratios—from compact, high-throughput units to longer, deep-cleaning designs—impact performance, power draw, and wear patterns.

Scrubber Series – Introduction to the Workhorse of the Wash Plant

In mineral processing, feed cleanliness can make or break recovery efficiency.
That’s where the rotary drum scrubber comes in — the quiet, tireless workhorse designed to free valuable minerals from clay, coatings, and other contaminants before they enter downstream circuits.

In the first article of our Scrubbers in Mineral Processing series, we explore:
🔹 What rotary drum scrubbers are and how they work
🔹 Why they’re critical for ore preparation
🔹 Where they fit in a typical flowsheet
🔹 Industries and applications — from diamonds to aggregates

Whether you’re designing a new plant or troubleshooting an existing one, understanding your scrubber’s role can unlock higher recovery rates and better efficiency.
