Airborne Geophysical survey Manono

Introduction

The JDE DRC SARL completed the airborne geophysical survey over two mining licences in the DRC: namely the Manono Pegmatite Mine and the Kalongo Lithium Mine. The initiative underscores the group’s strategic intent to deploy advanced exploration technology and to move from surface reconnaissance into deep-target generation in one of Africa’s most prospective critical-minerals provinces.

Project Background & Rationale

JDE Group is positioning itself as a turnkey exploration provider in the region, offering everything from airborne surveys to drilling campaigns. For the Manono and Kalongo assets, the rationale is two-fold:

Depth-extension of known pegmatite systems – The Manono area has historic and recent lithium-tantalum pegmatite activity; an airborne survey helps delineate deeper structures and repeat zones.
Efficient target generation in challenging terrain – Airborne geophysical methods allow rapid coverage over large tracts, reducing time and cost compared to wholly ground-based campaigns (especially where access is difficult).

As posted on JDE’s LinkedIn and Instagram feeds:

“We’ve passed the halfway mark of our airborne #MobileMT survey in the DRC … this world-class technology sets a new standard.”
“JDE DRC Nears Completion of Geophysical Surveys for Manono Pegmatite Mine and Kalongo Lithium Mine.”

Technical Approach

The survey uses advanced airborne electromagnetic (AEM) and/or passive magneto-telluric (MT) style technology — referenced by JDE as #MobileMT. Key features include:

High resolution resistivity and conductivity imaging of the subsurface, enabling detection of pegmatite bodies, alteration zones, and structural controls.
Full-scale coverage of both licence areas to capture major structural corridors and depth-extensions (rather than just visible outcrops).
Integration with JDE’s broader exploration workflow: following the airborne phase with ground follow-up (e.g., detailed EM, trenching, then drilling).

The company emphasises the benefits of “world-class technology” in raising the standard of exploration in the DRC.

Scope & Status

According to the latest update:

The survey over both Manono and Kalongo licences is “near completion”.
Airborne line kilometres appear to be well-advanced (though exact km-figures are not publicly disclosed).
Data processing, inversion and target generation phases are expected to follow shortly.
The group emphasises social-responsibility: using less intrusive airborne methods, enabling faster turnaround, and focusing on critical minerals.

Strategic Implications

For JDE Group this survey holds several implications:

Accelerated target pipeline: By detecting deeper zones and larger structural systems, the company can generate higher-value drill targets sooner.
Competitive advantage: Deploying leading-edge airborne tech positions JDE ahead of competitors in the region, signalling technological and financial capacity.
Lithium & strategic-minerals focus: The Kalongo lithium asset aligns directly with the global energy-transition trend (battery minerals), supporting JDE’s narrative of future-proofing exploration.
Local & regional impact: Faster, more efficient exploration can translate into earlier community benefits, job creation and infrastructure investment in the DRC.

Next Steps & Recommendations

For stakeholders and internal teams, the following are key next-steps:

Finalise the airborne survey and release interim data-maps, including depth slices, resistivity/conductivity images and structural maps.
Integrate survey outputs with existing geological, geochemical and structural datasets to prioritise drill-targets.
Plan a follow-up ground EM or induced-polarisation (IP) campaign to refine anomalies identified from the airborne survey.
Prepare drilling plans (budget, logistics, permitting) for early 2026 to capitalise on identified targets.
Communicate findings to investors and local communities, emphasising how the program supports job creation, local procurement and responsible exploration.
