Trap More Gold. Give It More Chances to Settle.

Stepped 4-sided pyramid riffle geometry designed to create repeated capture opportunities throughout the mat.

You've classified your material and dialed in your flow. The Step Pyramid Riffle Mat gives that material a structured recovery surface built around a repeating 4-sided stepped pyramid geometry.

As water and material move across the mat, the raised pyramid structures interrupt the flow and create repeated changes in velocity and localized settling areas.

Instead of relying on a single riffle line, the stepped pattern gives heavy material multiple opportunities to drop and hold as it travels through your recovery system.

Why the Step Pyramid Is Different

• 4-sided pyramid riffle geometry — interrupts flow from multiple directions across the mat surface
• Stepped structure — provides repeated edges and pockets where heavier material can settle
• Designed with fine-gold recovery in mind — multiple capture opportunities throughout the working area
• PETG construction — rigid, durable, and dimensionally stable for repeated field use
• Available in Red, Blue, and Green
• USA made
• Hand-inspected by HMO before shipment

Built for Controlled Recovery

The Step Pyramid pattern is designed to work as part of a properly tuned recovery system.

Water velocity, sluice angle, classification, feed rate, material composition, gold size, and overall equipment setup all affect recovery.

The mat's job is to provide a consistent series of recovery structures.

Your job is to give the material the right conditions to use them.

That makes the Step Pyramid useful whether you're working fine material through a compact sluice or incorporating it into a larger HMO recovery system.

Designed for HMO Gear — We Can Fit Yours Too

Step Pyramid mats are designed to fit HMO sluices and highbankers by design.

That is the standard configuration.

If you're running another brand, a custom-built sluice, or equipment of your own design, we can manufacture a Step Pyramid mat to fit your setup as well.

Contact us before ordering with:

• Inside sluice width
• Required mat length
• Available mat depth
• Equipment make and model, if known
• Any unusual mounting or fit requirements

Custom sizing is a premium service and priced accordingly.

Why PETG?

The Step Pyramid is produced in PETG to give the raised geometry a rigid, stable structure.

That makes it well suited for a mat design where the shape and spacing of the stepped riffles are part of how the recovery surface functions.

PETG also offers:

• Good impact resistance
• Low water absorption
• Consistent structural shape
• Lightweight construction
• Durability for repeated field handling

USA Made. Maker Direct.

We don't source Step Pyramid mats from a catalog.

We design them. We manufacture them. We inspect them.

Because they're developed alongside HMO sluices and highbankers, the mat and the recovery equipment can be treated as parts of the same system rather than unrelated components assembled afterward.

And when customers tell us what they're seeing in the field, that feedback comes directly back into future design and production decisions.

That's what maker-direct means at HMO.

Built Different. By Design.

Traditional recovery systems often rely on a few larger riffles or capture zones.

The Step Pyramid takes another approach.

Its repeating four-sided structures spread recovery opportunities throughout the mat surface, giving heavy material repeated chances to slow, settle, and remain behind a structure.

Different geometry. Different recovery surface.

Run it. Tune it. Watch what your material tells you.
