Photon Assay
Photon Assay Facilities, Engineered & Built
Photon assay represents one of the most significant shifts in gold analysis in over a century. Compared to traditional fire assay, it's faster, non-destructive, and handles much larger sub-samples — improving representativity for coarse gold mineralization and dramatically reducing per-sample turnaround. But the technology itself is only half the equation. Deploying it onsite requires a facility engineered specifically for what photon assay needs.
As photon assay has rapidly gained industry acceptance, so has its inclusion in inquiries received by Modular Lab Solutions. The size and infrastructure necessary for the photon assay equipment requires a larger footprint than can be contained in our traditional modular structures. Our sister company; G2 National, specializes in commercial wood framed structures. Working together we have developed a Commercial Structural Shell (CSS) custom designed, and with the supporting infrastructure to house photon assay installations, accompanied by our more traditional modules to address sample prep and any other lab functions required by the project.
This page shows two halves of the same project: a purpose-built photon assay facility with integrated sample preparation, and the G2 Commercial Structural Shell (CSS™) engineered wood-truss construction system that makes building that facility fast, predictable, and site-friendly.
A complete photon assay workflow under one roof — receiving to result.
Twin-console photon assay with integrated sample prep.
The PA-P2-V1 layout brings the full photon assay workflow — from sample receiving through prep, drying, crushing, and analysis — under a single 52' × 52'-11" roof. The Rocklabs Mid Boyd twin-console configuration is paired with dedicated Linac, Modulator, and Automation cabins, sized to support production throughput onsite.
Receiving & Drying
Sample intake with Alsto 2M3 drying ovens and drying rack staging — the first hand-off in the workflow.
Crushing
Twin Rocklabs Boyd Crusher RSD stations with paired consoles, designed for high-throughput sample preparation.
Photon Assay
Automation, Linac, and Modulator cabins housed in their own shielded zone, with chiller and compressor support adjacent.
Support & Utilities
Electrical, dust collection, make-up air, and QC hood — sized for sustained production-scale operation.
The shell that makes it possible — built off-site, assembled fast.
G2 Commercial Structural Shell.
Photon assay facilities need real structure — shielded equipment cabins, load-bearing roof spans for ventilation and dust collection, and a building envelope that can be erected quickly and on a tight site. The G2 CSS™ system uses prefabricated engineered wood components — including the proprietary G2T™ open-web truss — manufactured in plants across the country and assembled onsite in days rather than weeks.
Engineered for the loads modular labs need to carry.
The structural shell is more than a building — it's an engineered platform that has to accommodate shielded photon assay cabins, dust collection systems, make-up air units, and HVAC loads, all while spanning the working zones of a busy lab floor below. The G2T™ open-web truss system gives a shallower roof envelope than traditional construction, with engineered fastener patterns and connection details designed and stamped for the specific project.
Because the wall panels and trusses are prefabricated off-site at G2's manufacturing plants, the work that happens onsite is mostly assembly — not framing from raw lumber. That changes what site conditions you need, what labor mix is required, and how long the structure takes to close in.
Engineered Loads
G2T™ trusses are designed and stamped for the actual loads the lab will carry — equipment, mechanical, snow, wind, seismic.
Prefab Components
Wall panels and trusses arrive on site ready to assemble, with fastener patterns and connection details predefined.
EOR Services
Engineer-of-Record services available through G2 ProServ in conjunction with the structural shell deliverables.
Wood-Framed
Engineered wood construction with lower embodied carbon than equivalent steel-framed structures.
What the construction sequence looks like.
The G2 CSS™ system is engineered for rapid site assembly. The scroll-driven build sequence above shows the construction animation; the phases below summarize how a typical lab shell comes together over a handful of working days.
Wall Panel Erection
Prefabricated wall panels arrive and are set on the prepared slab. Anchoring and panel-to-panel connections completed.
G2T™ Truss Installation
Open-web wood trusses are lifted into place, connected to bearing walls, and locked in with engineered fasteners.
Bracing & Sheathing
Permanent bracing installed, structural sheathing applied. The shell is now load-bearing and weather-ready.
Envelope & Fit-Out
Roofing, exterior finishes, and interior fit-out begin. Lab equipment installation follows the structural close-in.
