01
Exploration and targeting
Geological interpretation, near-mine targeting and drill programme design. We pull your geology, geochemistry and spatial data together so the next hole goes where it will teach you the most.
Resource geology · Geoscience software
Get the geology right, and the numbers follow.
DeepFusion Geoscience is a Tanzanian resource geology practice that also builds its own software. We help explorers, mine operators and project owners model their deposits, check their data and report with confidence, from the core shed to the resource statement.

01 · Services
From the first target to the ore you send to the mill.
Practical geology for people who have to make a decision: where to drill next, how much is really there, and whether the numbers will survive a review.
02
Geological modelling and resource estimation
Drillhole validation, domaining, compositing, variography and block models. We start with the geometry of the mineralisation, then estimate, validate and document the basis for classification.
03
JORC and NI 43-101 reporting
Preparing and reviewing geology and resource reporting, including JORC 2012 Table 1 and contributions to NI 43-101 technical reports, with methods, assumptions and risks stated plainly.
04
Mine geology and grade control
Grade control models, ore and waste boundaries, dilution and ore loss, and reconciliation of the model against what the plant actually received.
05
Data checks and due diligence
Drillhole database validation, sampling and assay QA/QC, and independent reviews of resource models. We find the gaps and the risks, and tell you what to do about them.
06
Studies and training
Geological inputs to studies, linking the resource to mine planning, and hands-on mentoring for site teams in modelling, grade control and data quality.
Professional accountability. For every assignment we agree the scope, the reporting code and who is responsible. Whether a Competent Person (JORC) or Qualified Person (NI 43-101) role can be taken on, including experience and independence, is assessed project by project. Reserve reporting also needs modifying factors and input from other disciplines. See the JORC Code and the NI 43-101 instrument.
02 · Software
Tools we built because we needed them on site.
Every product here started as a problem we kept running into on real projects. They are built by geologists, for the people who log, check, model and sign off.
Available now
GeoLedger
A drillhole database for mining companies where every hole, every assay and every decision stays on the record. Logging, sample dispatch, lab QA/QC, batch sign-off and model exports sit in one place, so when an auditor or a buyer asks which assays went into the model, the answer takes minutes, not weeks.
- Every edit keeps the old value, the new value, who made it and why, and can be rolled back.
- Lab batches are screened against your standards, blanks and duplicates before a Competent Person releases them.
- Offline logging on a tablet, chain of custody to the lab, and export packs for Leapfrog, Datamine and Micromine.
- Gold or base metals, one company or several on one installation, running on your own mine network.
1 · LogCode-list logging in the core shed, with gaps and overlaps caught at the tray.
2 · DispatchQC samples inserted at your rates, every hand-over signed.
3 · ReleaseBatches screened, then accepted or rejected with a written reason.
4 · ExportOnly released data goes to the model, with a manifest.
The live demo runs on a fully fictional mining company with three operations, so no client data is ever shown.
Technical preview
DeepRBF
A 3D geological modelling and geostatistics engine for working out the shape of a deposit, how far grade continues, and how sure you can be. It is built around one idea: get the geometry of the mineralisation right, using all the data, before worrying about anything else.
- Implicit and categorical modelling of ore shells and geological domains.
- Variography, kriging and conditional simulation in the same workflow.
- Diagnostics and reproducible runs, so a model can be checked by someone else.
- Used for
- Ore-shell and domain modelling, grade estimation, uncertainty and drillhole planning
- Deposits
- Tested on orogenic gold and volcanic-hosted massive sulphide data
- Access
- Controlled preview for project work and research partners
In development
DeepFusion GeoAI
A working environment that brings project files, geological knowledge and scientific workflows together, so the reasoning behind a technical output can be traced back to its sources and reviewed.
- Focus
- Geoscience knowledge and document workflows, project data, and traceable outputs for technical review
03 · How we work
A model is only as good as the evidence behind it.
We keep geological reasoning, data support and honest assumptions at the centre of the job.
01
Start with the evidence
Understand the question first, then look hard at the source data and the geological setting before anything gets modelled.
02
Build it, then try to break it
Test the interpretation against the data, look at how the model behaves, and show the uncertainty rather than hide it.
03
Leave a trail someone can follow
Tie every output to its inputs, assumptions and limits, so the people who rely on it can check it for themselves.
04 · About us
Field experience, with the rigour to model it.
DeepFusion Geoscience Limited is based in Dar es Salaam. We bring exploration and mining geology together with geological modelling, geostatistics and software we write ourselves, to give clients the geological understanding they need to make project decisions.
The practice is built on founder Ramadhani Ndonde's career of more than twenty years across operating mines, exploration programmes and consulting work in Tanzania, Zambia, Burundi, Saudi Arabia and Eritrea, on gold, copper, polymetallic VMS, iron ore and limestone projects.
That career includes senior resource geology roles at Asmara Mining Share Company and Stamigold, group mineral resource management at Saudi Gold Refinery Company, and mine geology at Lumwana, Geita and Resolute's Tanzanian operations. It covers kriging and simulation, resource model validation, drilling strategy, grade control, reconciliation and building up site teams, and it shapes how DeepFusion works: geology first, clean data, and results that can be reviewed.
This is Ramadhani Ndonde's individual career history, including roles before DeepFusion was founded. Former employers and projects are not presented as DeepFusion clients.
