EXPERIENCE
With over 22 years in airborne geophysics services and a collective exceeding 200 years of industry expertise, AeroPhysX delivers world-class survey solutions.
We specialize in technologies that drive new value for exploration, environmental studies, and mineral resource development.
Our team brings deep, proven experience across Africa and other emerging markets, working with leading mining firms, government agencies, private prospectors, and landowners.
HISTORY
AeroPhysX was founded to transform exploration using cutting-edge technology in Africa and beyond.
Our global operations focus on offering UAV, fixed-wing and helicopter magnetic, radiometric and EM surveys, from data acquisition through to final mapping.
We have owned and operated a range of aircraft platforms including fixed-wing and helicopters, with approved installations across all major types, as well as standard and heavy-lift UAV’s.
VISION
Our vision is to deliver high-performance, cost-effective airborne surveys while advancing the frontiers of geophysical technology.
We were early pioneers in drone-based magnetic surveying and the first in Africa to implement the Magarrow system.
Today, we lead in UAV survey innovation and are actively developing advanced software tools for terrain following, navigation, and data processing.
MISSION
We strive to be the world’s most trusted provider of accurate, efficient, and client-focused airborne survey solutions.
By continuously integrating new technologies and refining methodologies, especially in drone-based workflows, we aim to set a new standard in data acquisition.
Our team has collaborated for over seven years on developing high-end processing techniques and scalable systems that empower smarter, faster exploration.
At AeroPhysX, exploration is in our DNA. Our global footprint stretches from the deserts of Namibia to the rainforests of Papua New Guinea, across the gold belts of West Africa and into the resource-rich landscapes of the Americas. Every project is a journey into new terrains, new partnerships, and new possibilities —our global reach mirrors our drive for innovation. We have delivered cutting-edge geophysical data acquisition in over twenty countries — each site pushing us to refine, adapt, and advance. Our expanding footprint is a testament to our commitment to precision technology, client satisfaction, and adherence to both international and local standards.
