What is Xcalibur Smart Mapping’s current focus in Saudi Arabia?

At Xcalibur, we focus our efforts on large-scale government partnerships, leveraging our full suite of technologies and expertise. In Saudi Arabia, our centerpiece project is our work with the Saudi Geological Survey (SGS). Since early 2022, Xcalibur has deployed multiple aircraft and teams to map approximately 600,000 km2 as part of Phase 1 of the SGS’ Regional Geological Survey Program (RGP), which is scheduled to conclude by the end of 2025. Through our local subsidiary, we have also supported clients such as Ma’aden and helped to develop local Saudi expertise to Xcalibur’s international standards.

What has Phase 1 of the RGP involved, and what will later phases entail?

Xcalibur’s Phase 1 work with the SGS focused on broad geological mapping, using magnetic, radiometric and remote sensing techniques to establish a foundational understanding of structures, tectonics and potential mineralization. Phase 1 identified areas with the highest exploration potential but did not provide direct detection of deposits.

In Phases 2 and 3, more advanced technologies including electromagnetics, gravity and gamma ray spectrometry will be applied to enable direct or inferred detection of concealed deposits. We are hopeful for potential involvement in the program.

What are the key technologies Xcalibur utilizes?

Our foundational exploration techniques include magnetics and  gamma-ray spectrometry. For higher-resolution and targeted exploration, Xcalibur employs electromagnetic (EM) systems, available in both helicopter and fixed-wing formats. Our fixed-wing TEMPESTEM system transmits a square wave to record the ground response from multiple frequencies simultaneously, ideal for large-scale regional programs.

We also leverage gravity gradiometric measurements through our FALCON system. Gravity tensor analysis provides high-resolution imaging from surface to depth.

By integrating all this data utilizing machine learning, we generate comprehensive subsurface models, assessing data in real time to determine the most suitable methodology for the scale and resolution required.

How do Xcalibur’s techniques help to reveal resources under cover?

Traditional exploration techniques struggle to detect deposits beneath 30 to 50 m of sedimentary or regolith cover. Leveraging multi-physics geophysics and machine learning, we build models to infer the location and economic potential of these concealed deposits. By integrating diverse datasets and advanced analytics, we can systematically explore undercover resources, unlocking significant new mineral opportunities that were previously inaccessible through conventional exploration methods.

What is the focus of Xcalibur’s R&D efforts today?

A key focus is surface mapping for emerging energy resources, including natural hydrogen. With growing global interest in hydrogen hubs, Xcalibur is developing techniques to measure hydrogen concentration at the earth’s surface. Using our gravity gradient and geophysical imaging expertise, we can also map subsurface structures to identify potential hydrogen reservoirs, supporting clients and positioning Xcalibur at the forefront of novel exploration methods for critical energy transition resources.

How does regional-level data help mining companies’ exploration efforts?

Access to regional-scale geological data is a key differentiator for companies seeking to explore effectively. Most mining companies are constrained by the need to license or purchase concessions, which limits their ability to assess large areas. By providing country-scale insights, Xcalibur allows clients to strategically focus on specific regions or prospects, linking broad geological understanding with targeted, on-the-ground exploration.

What will be Saudi Arabia’s strategic role in global mining value chains in the coming years?

Saudi Arabia is exceptionally well positioned to meet the coming surge in global demand for critical minerals. With projected demand increasing four- to tenfold by 2050, discoveries made over the next decade will be crucial, given that bringing a deposit to market can take up to ten years.

Areas under sedimentary cover and complex tectonic environments hold the potential for tier-one deposits, which could significantly influence global mineral geopolitics and strategically position the Kingdom as a leading supplier of critical resources.

What will be Xcalibur’s priorities in Saudi Arabia in 2026?

Our strategic priority globally is to continue positioning Xcalibur as a trusted partner to governments. In Saudi Arabia, the focus is on integrating our subsidiary, the Arabian Smart Mapping Company, more fully into the Xcalibur group. Under new leadership, ASMC will draw on global resources and expertise, enabling us to execute complex projects and reinforce Xcalibur’s role as a strategic, technology-driven partner in the Kingdom and beyond.
