XRF in your backpack, lab in your hand - how rugged real-time tools are helping explorers strike faster, drill smarter, and stay one step ahead in the field

From deserts to drill pads, remote exploration teams increasingly need to make informed, high-impact decisions without waiting weeks for lab results. It’s this push for speed, accuracy and portability that’s seeing handheld X-ray fluorescence (XRF) technology move from a niche accessory to a frontline tool in modern geochemistry.

Few know this shift better than Beck Kinsella, sales specialist - analytical instruments at Evident industrial. In an in-depth Q&A with The Rock Wrangler, Beck outlines how the company’s Vanta XRF analysers are giving geologists rugged, rapid and reliable elemental insight - right where and when they need it most.

Real-time results in the middle of nowhere

“Geologists regularly face challenges when collecting accurate, real-time data in the field, especially under changing environmental conditions,” says Beck.

Field sampling rarely happens in pristine lab-like conditions. Whether contending with overlapping elemental spectra, variable sample matrices or just plain logistical remoteness, geologists often operate without the analytical safety net of a full lab setup.

That’s where the Vanta handheld XRF system comes in.

“The analyser delivers real-time results, which helps geologists make informed decisions without waiting for lab turnaround,” Beck explains. “It’s capable of detecting a broad range of elements, from magnesium to plutonium, with high sensitivity and robust performance - even in harsh environments.”

From scouting to smart sampling

Vanta isn’t about replacing laboratories; it’s about enhancing and focusing their role.

“Handheld XRF provides immediate on-site elemental analysis, helping geologists quickly identify areas of interest and focus their sampling efforts,” Beck says. “By distinguishing between high- and low-priority samples in the field, it reduces the number of samples that need to be sent for lab analysis, lowering the overall cost per sample.”

This ability to screen and stratify samples in the field not only accelerates exploration, it minimises unnecessary drilling, lab throughput, and project cost.

“It’s about streamlining the entire exploration workflow,” Beck adds. “That real-time insight supports more informed decisions from day one.”

Speed and sensitivity where it counts

Evident’s latest Vanta models pack impressive analytical punch.

“Our instruments offer industry-leading precision with detection limits down to single-digit parts per million for many elements,” says Beck. “Results are delivered in seconds, which is crucial when you’re screening dozens or even hundreds of samples in a day.”

Beck points out that the core of this performance lies in silicon drift detectors and sophisticated software algorithms married to a rugged chassis designed for life on the move.

Designed for the demands of the field

If there’s one thing Evident isn’t compromising on, it’s durability.

“Vanta is built for rugged field use,” Beck says. “It has an IP rating for water and dust resistance, has been drop-tested from four feet, and operates reliably in temperatures ranging from -10°C to 50°C.”

Add in swappable batteries, built-in GPS, cloud connectivity, and a touchscreen interface optimised for gloves and glare, and you’ve got a tool made to thrive where laptops and lab kits fear to tread.

“There’s a lot of thought that’s gone into making this easy to use for multi-user teams, even in the most remote and demanding environments,” says Beck.

Broad applications, tangible outcomes

With the ability to analyse elements from magnesium through uranium, Vanta handheld XRF instruments are proving invaluable across a wide variety of commodities and mineral systems.

Beck explains that Vanta is used throughout the mining lifecycle - from early-stage exploration through to grade control and environmental monitoring.

In base metals exploration, for instance, Vanta is well suited to rapidly screening for copper and zinc mineralisation. In precious metals work, it helps geologists identify pathfinder elements to zero in on gold-bearing zones.

While direct lithium measurement remains limited, Beck says Vanta is particularly effective at detecting associated indicator elements such as potassium, rubidium, and caesium. Rare earth element (REE) exploration is another area where Vanta is delivering strong value, especially with recent hardware upgrades.

“It’s the combination of ruggedness, analytical range, and speed that makes Vanta so valuable in high-throughput or remote exploration programs,” Beck notes.

Data where you need it - instantly

Modern exploration programs are becoming increasingly digital and decentralised, and Beck highlights how Evident has embraced this with Vanta’s connectivity suite.

“With Wi-Fi, Bluetooth, and USB, you can immediately sync your data to cloud platforms or centralised databases,” Beck says.

For teams running advanced workflows, the Vanta API supports Python scripting, enabling custom data processing, automation, and real-time integration with broader analytics platforms.

“This is especially valuable for high-volume projects that require fast, robust interpretation of XRF data.”

Built-In QA/QC for reliable multi-user deployment

Maintaining quality across multiple sites, shifts or users is always a challenge in field-based work but Beck says Vanta has it covered.

“Vanta supports multiple calibration modes tailored to different applications like mining or soil,” she explains. “There are onboard QA/QC tools, and users can develop custom calibrations and upload them to the cloud.”

Validation routines and check standards can be baked into daily workflows, ensuring reliability and reproducibility regardless of who’s on the trigger.

“This is critical for teams working across multiple sites or needing to maintain compliance with internal quality systems.”

Field-proven success stories

The value of Vanta isn’t just theoretical - it’s already improving performance on the ground.

“One recent example was an iron ore project in Western Australia,” Beck shares. “The Vanta was used to streamline pit mapping and validate blast hole data on site. That meant faster decisions and reduced reliance on lab assays cutting several weeks off turnaround and keeping operations moving.”

In another case, a base metals explorer used Vanta for in-field core logging during a Cu-Zn program. The geologists were able to identify zones of elevated copper and zinc concentrations directly on-site, which let them prioritise drilling in real time, fine-tune their exploration strategy, and avoid unnecessary metres ultimately saving time and money.

In both cases, Beck says, Vanta helped refine geological models and accelerate project momentum.

Next-gen capability for REEs

One of the most exciting developments, according to Beck, is the new Vanta Max XRF equipped with a 55 kV X-ray tube.

“This upgrade significantly enhances sensitivity for high atomic number elements,” she says. “It’s especially effective for rare earth elements like cerium, neodymium, and gadolinium which are notoriously hard to detect accurately in the field.”

The enhanced voltage generates stronger signals and improves detection limits, providing a key advantage in REE exploration, particularly at the early stages when subtle signatures can make or break a target.

“It retains all the ruggedness of the original - drop-tested, wide operating temperature, IP-rated, cloud connected, but it’s now an even more powerful tool for geochemists working on critical minerals.”

A tool geologists actually want to use

Ultimately, Beck says the real power of Vanta lies in how well it aligns with the realities of field work.

“Geologists want tools that are reliable, intuitive, fast, and tough,” she says. “The fact that Vanta delivers lab-level performance while fitting into a backpack is what makes it so valuable.”

For explorers trying to de-risk drilling decisions, optimise workflows, or just get ahead of the curve, Vanta is more than just a gadget - it’s a decision-enabler.
