DEMSA GLOBAL

Argentina has the mineral.
The world has the capital.

Between them sits a problem, and it isn't geological.

It is a problem of trust.

Titles unverified. Reports never cross-checked. Risks that surface only in due diligence, once six months are already gone.

What we do

We validate every opportunity before showing it.

Ownership checked against the mining registry, concession validity verified, technical reports reviewed, and risks declared up front.

How it works

Six stages. More access, more commitment.

From the public card to closing and on to the services account. No one sees the full file without signing; no one signs without knowing what they will see.

And when the deal closes, the work is only beginning.

River logistics, ports, offtake and export — forty years of Southern Cone operations behind every agreement.

Coming soon.

Access is by invitation and opens in stages. The calendar goes to the early-access list.

The platform

Ask in plain language. The platform answers with the file in hand.

This is not a listings search. Behind every answer sits a validated file: mining registry, title, technical reports and environmental status, reviewed by analysts with AI assistance. Every claim traces back to its source.

Demo data

How it works

From interest to agreement, in six clear stages.

Each stage opens more information in exchange for more commitment. No one sees the full file without signing; no one signs without knowing what they will see. The E0–E5 model orders the whole process and is implemented in the software.

Validation

The difference isn't the listing. It's what sits behind it.

The mining platforms that exist solve discovery: they publish open listings. The international buyer's problem is not finding the asset, it is believing it. Every opportunity that enters DEMSA MDI goes through ownership verification in the mining registry, a check on concession validity, cross-checking of the technical reports and a review of environmental status before it is published.

✓ Ownership and validity checked against the public registry
✓ Risks declared up front, not discovered in due diligence
✓ Watermarked documents in a protected viewer, traceable per user
✓ Digital NDA and mandate: every access is logged

After closing

The agreement doesn't end the deal. It starts it.

A mining asset that has been sold still has to get out. That is where the DEMSA ecosystem comes in: river transport on the Hidrovía Paraná–Paraguay, port infrastructure re-engineering, offtake agreements and access to ocean ports. Every closing becomes a services account with a life of its own — the company's third revenue engine.

Why now

International capital is looking for a way in, and nowhere trustworthy to look.

⛏

Critical minerals

The energy transition pushed global demand for lithium, copper and rare earths. Argentina is on the map for all three.

🇪🇺

Mercosur–EU

The agreement opens the European market to regional production and brings buyers who demand documentary traceability.

📐

RIGI and fiscal stability

Argentina's incentive regime and 30-year fiscal stability changed the return calculation on large projects.

🧩

An informal market

Concessions change hands through contacts, spreadsheets and loose PDFs. Discovery is solved. Trust is not.

What's coming

The platform is already being built. It opens in stages.

DEPLOYED

The core, running

Identity and organisations, the E0–E5 stage engine and the opportunity repository, running in both the development and production environments.

UNDER CONSTRUCTION

The complete file

Document and mapping repository with permissions and a protected viewer, digital NDA, Deal Room, and the competitive process end to end.

IN PREPARATION

The seed portfolio

The first concessions, our own and our partners', enter validation so they are published the day the platform opens.

IN DESIGN

The corridor

Brazil and Asia-Pacific, agreements to purchase future production, and the post-closing services account running at full capacity.

The company

A technology company with forty years of mine and port behind it.

DEMSA GLOBAL is born where two worlds meet that almost never do: the world of the mine, the barge and the port, where a decision is measured in decades, and the world of software, where the paradigm turns over every five years. Out of that meeting comes an idea the industry still does not have: that the information behind a mining asset be delivered as a verified, traceable product — and not as a folder passed from hand to hand.

Shareholder

Desarrollo y Exploración Mineral S.A.

It has operated since the 1980s in the ports of the Hidrovía Paraná–Paraguay — San Nicolás, Rosario, Ramallo, Zárate — and in ocean ports through alliances. Today it concentrates on river transport of minerals, port infrastructure re-engineering and opening new markets.

Its ground is the physical mineral: the concession, the barge, the ship's hold and the buyer on the other side of the ocean. Its commercial network reaches Brazil, China, India and the Argentine mining provinces.

About DEMSA →

Shareholder

Guios Sistemas S.R.L.

Thirty-three years writing software and not one of them repeating the last. It was born in 1993 and crossed every move the trade has made without settling into any of them: the in-house datacenter, virtualisation, private cloud, public cloud, DevOps, DevSecOps.

Today its trade is a decision almost nobody is making yet: which processes have to stay software, and which can already be agents. It is the same decision that fifteen years ago was whether to move to the cloud — and that one, too, looked like it could wait. It is why this company exists now and not ten years ago.

Access by invitation

The platform opens in stages. The first accounts are chosen by hand.
