I ran the license document through ChatGpt regards temporary mining licenses. As many of us understood, a temporary mining license can be applied for in Brazil and this is usually done after resource estimation.
Yes — a limited amount of gold can legally be produced during the exploration phase in Brazil, but only under specific conditions.
The permit mentioned in your document is an “Autorização de Pesquisa” (Exploration Authorization) issued by the Agência Nacional de Mineração (ANM). Normally, this permit only allows geological exploration, not commercial mining. However, Brazilian mining law allows a special mechanism.
1. Normal Rights Under an Exploration Permit
With an Autorização de Pesquisa, the company can:
Conduct geological mapping
Drill and sample ore
Excavate test pits or trenches
Perform laboratory analysis
Estimate mineral resources
But commercial production is not automatically allowed.
2. Exception: Trial Mining / Bulk Sampling
Brazilian law allows limited extraction during exploration through what is called:
“Guia de Utilização” (GU)
This authorization is also issued by the Agência Nacional de Mineração.
It allows the company to:
Extract limited quantities of ore
Process and sell the mineral
Generate revenue to fund exploration
3. Typical Limits
The limits depend on the mineral and project, but generally:
For gold projects:
Small-scale production may be allowed
Usually temporary
Quantities are capped
Must be justified as testing or pilot production
The company must show that extraction is necessary for:
Metallurgical testing
Pilot plant operation
Economic feasibility studies
4. What Happens Next
The usual progression for a project like the one in Itaituba, Pará is:
1️⃣ Exploration Permit (Autorização de Pesquisa)
2️⃣ Exploration work and resource estimation
3️⃣ Guia de Utilização (optional early production)
4️⃣ Final Exploration Report submitted to ANM
5️⃣ Application for Mining Concession (Lavra)
6️⃣ Full commercial production
5. Important Practical Reality
In many gold areas of Pará, companies do apply for a Guia de Utilização because it allows:
Early cash flow
Testing of processing plants
Small-scale gold recovery
Without this additional authorization, producing and selling gold would be illegal under the exploration permit alone.
✅ Summary
Under the license shown in your document:
Exploration activities are allowed.
Gold production is only allowed if a “Guia de Utilização” is granted by ANM.
That production must be limited and justified as part of testing or feasibility work.
If you want, I can also explain something important about your specific process 850.782/2005:
Whether that region of Itaituba is known for high-grade gold deposits
What the approximate land size of the license likely is
How much a license in that area can potentially be worth
