The Brazilian Commission of Resources and Reserves – “CBRR” was established in 2015 and is formed by the Alliance of three of the most important and representative associations of the Brazilian mineral sector: Brazilian Association of Mineral Research Companies – “ABPM”, Brazilian Agency for Technological Development of the Mineral Industry – “ADIMB” and the Brazilian Mining Institute – “IBRAM”.
The CBRR is a private non-profit organization focused on establishing, promoting and managing efforts to foster and develop the Brazilian mineral sector. Its initiatives include: dissemination of global best practices in engineering and geology, guidelines for the declaration of Exploration Results, Mineral Resources and Reserves in accordance with the standards established by CRIRSCO, management of the certification process and a database for the registration of Qualified Professionals in Brazil. The CBRR registers professionals, and as part of the registration process, determines qualifying domain areas. For professionals registered in these areas, the term “Registered Qualified Professional” is used.
The “CBRR guide” describes and recommends the minimum criteria and guidelines for public reporting in Brazil of Exploration Results, Mineral Resources and Reserves. On May 5, 2015, the CBRR signed a memorandum of understanding with CRIRSCO, establishing the procedure for the formal acceptance of the CBRR into CRIRSCO, scheduled to take place during its annual meeting held in Brasilia in December 2015.
Since 1994, CRIRSCO has worked to create a set of standard international definitions for preparing Statements of Exploration Results, Mineral Resources and Reserves.
CRIRSCO was initially a committee of the Council of Mining and Metallurgical Institutions (“CMMI”). In 2002, CMMI was dissolved, but CRIRSCO remained as a separate entity and currently has a direct relationship with the “International Council on Mining and Metals” (ICMM) from whom it receives support. Currently there are 8 (eight) member countries through their National Reporting Organizations (NROs); Australasia (JORC), Canada (CIM), Chile (National Committee), Europe Union (PERC), Mongolia (MRC), Russia (NAEN), South Africa (SAMCODES) and the United States (SME), being Brazil, via CBRR, the newest official candidate for inclusion in 2015.

Public Statements
Public Statements are prepared to inform investors or potential investors and their advisors about Exploration Results, Mineral Resources or Mineral Reserves. They include, but are not limited to, entities’ annual or quarterly reports, press releases, information memoranda, technical documents, website postings and public presentations.
Statements can be issued for all solid minerals, including diamond, other gems, industrial minerals, rocks and aggregates, and coal, for which the relevant regulatory authorities require the Public Statement of Exploration Results, Mineral Resources and Mineral Reserves.
A Public Statement regarding an entity’s Exploration Results, Mineral Resources and/or Mineral Reserves is the responsibility of the entity, acting through its Board of Directors. A Public Statement of this nature should be based on and fairly reflect information and documents prepared by Qualified Professionals.
The documentation detailing Exploration Results, Mineral Resource Estimates and Mineral Reserve Estimates, on which the Public Statement is based, must be prepared by or under the supervision of Qualified Professionals and be signed by them. The documentation must provide a true representation of the Exploration Results, Mineral Resources or Mineral Reserves being declared.
A Qualified Professional is a mineral industry professional registered with the Brazilian Resources and Reserves Commission (CBRR) or a ‘Recognized Professional Organization – RPO’, listed in Annex 3. The CBRR and the RPOs have enforceable disciplinary processes, including the power to suspend or exclude members.
A Qualified Professional registered with the CBRR must have at least ten (10) years of professional experience and at least five (5) years of relevant experience in the style of mineralization, type of deposit considered and in the activity for which the person assumes responsibility, including at least three (3) years in a Position of Responsibility.

Resource Exploration and Estimation – PQ-CBRR
The CBRR Registration Committee recognized the competence of Geologist Giancarlo Silva in the areas of Mineral Exploration and Mineral Resource Estimation for sand, gravel, gravel and construction gravel, as well as clay for red ceramics on June 10, 2022. The Geologist is currently registered under number 022125 and listed with the CBRR as a Registered Qualified Professional.
The professional registration at CBRR ratifies IGNEABR’s commitment to transparency, materiality and competence required in public documents in the area of Mineral Exploration and Mineral Resource Estimation.
