In research just released, MCKINSEY finds that worldwide mining operations are as much as 28 percent less productive today than a decade ago.The report follows by saying that the pronounced decline in productivity is evident across different commodities and is seen in most mining players and geographies.

Compared with industries such as automotive, which obsessively focus on productivity gains, the numbers seem astonishing. Nevertheless, the decline may be less surprising when we take into account the fact that the industry has just ridden a demand supercycle and has succeeded in expanding production of certain major commodities by 50 percent or more over the past decade.

Seven of the world’s leading diamond mining companies today announced their commitment to form the Diamond Producers Association (DPA). The founding members – ALROSA, De Beers, Rio Tinto, Dominion Diamond Corporation, Lucara Diamond Corporation, Petra Diamonds Ltd, and Gem Diamonds Ltd will work together to support the development of the diamond sector.

The DPA is the first ever international representative organization to be formed by some of the leading diamond producers, with a corporate registration in London, England. The DPA’s remit will include:

  • Maintaining and enhancing consumer demand for and confidence in diamonds including joint category marketing initiatives;
  • Providing a reliable source of industry information, including trade and consumer research;
    Acting as the unified voice of the diamond producers, when required and/or appropriate, with industry and non-industry forums/organizations;
  • Communicating the role and contribution of diamond producers to the diamond sector and broader society; and
  • Sharing best practices in health and safety, licence to operate, supply chain integrity and environment management.

The DPA will play an important and positive role in the diamond sector. It will actively engage with industry and non-industry organisations to promote the interests of the sector. The DPA will operate in compliance with all applicable competition/antitrust laws. It will have an initial minimum annual budget of US$6 million, based on commitments of founding members. This budget will enable the DPA to start operating effectively as soon as an Executive Director has been recruited. It will be reviewed annually based on the activity plan submitted to the Board for approval.

A recruitment process has been initiated to appoint the Executive Director who will be responsible for the operational activity of the DPA and report to the Board. Along with the incorporation of the organisation, the appointment of an Executive Director and of a focused support team, the DPA’s 2015 activity plan includes the commissioning of research as a base to building a targeted activity plan for the next three years.

Center for Entrepreneurial GeosciencesEntrepreneurial geologists have been around since at least the Bronze Age and have introduced many new materials and technologies. The Center will pursue such creative people, and those who aspire to help develop new ways of responding to commodity needs today, guiding them to recognize, and acquire the skills they need.

The UTEP (The University of Texas at El Paso) Department of Geological Sciences is developing a unique educational idea: Entrepreneurial Geosciences: We say that the ‘discovery’ phase of resource development is unique, and we propose a Center of learning devoted to that phase of resource development. This is the entrepreneurial and high risk-taking stage of resource development and production. Certainly, subsequent entrepreneurial actions add to the value or lower the cost of the product.

The Center’s mission includes “To become a nationally and globally significant Center for the development of entrepreneurial leadership in mineral and energy exploration, as measured by student output and longer term success, educational quality, industry participation, and research and development contributions to the field. The Center will provide students with financial support, technical expertise, research facilities, opportunities to think out-of-the-box, and connections to industry. Understanding the character of the entrepreneurial mind, geotechnical success of discovery, and the requirements of company development, will be constant objectives. Upon satisfactory completion of requirements, the Center will grant Certificates and access to Degrees.

A atividade de perito-classificador-avaliador de diamantes em bruto em território nacional só pode ser exercida por quem for detentor de título profissional válido e reúna condições de idoneidade, sendo a INCM a entidade competente para o procedimento de habilitação e emissão do respetivo título, nos termos da Lei n.º 5/2015, de 15 de janeiro, e da Portaria n.º 109/2015, de 21 de abril.
A pessoa singular que reúna as condições necessárias e que pretenda obter o título profissional de perito-classificador-avaliador deverá submeter-se a exame a realizar na INCM, composto por uma parte teórica e por uma parte prática.
A Lei determina ainda que a INCM é a entidade competente para a impressão dos certificados de importação e exportação de diamantes em bruto, cuja emissão, validação e verificação competem à Autoridade Tributária e Aduaneira.

Vai realizar-se no dia 1 de Junho o exame para Perito – classificador –avaliador de diamantes – anúncio do exame, aqui, que preencherão, nos termos da Lei 5/2015 uma função crítica no processo de importação e exportação de diamantes em bruto. A Portaria 109/2015 estabelece, também, algumas condições para o exercício daquela função.

O exame tem uma estrutura e critérios já definidos e afixados.

No próximo dia 18, realizarei um workshop no INCM para esclarecimento de dúvidas relativamente ao processo de acreditação de perito – classificador – avaliador. Em particular, serão abordada as questões:

  • Classificação de diamantes em bruto no Sistema Harmonizado.
  • Estrutura do relatório a emitir pelo Perito – classificador –avaliador no âmbito do processo de importação – exportação de diamantes em bruto.

O acesso ao workshop é livre mas limitado à lotação da sala e implica uma inscrição prévia. Basta contactar-me através do meu e-mail:

O tempo urge, pelo que havendo interesse, é necessário iniciar o processo de candidatura e manifestar o interesse junto do INCM – Contrastaria. A melhor pessoa a contactar na Contrastaria a este propósito é a Dr.ª Helena Felgas.

The source of diamonds in the Diamantina (Minas Gerais) region: Fm. Sopa – Brumadinho

Conglomerado Sopa (Sopa – Guida outcrop)

The precambrian Sopa Conglomerate is the source for modern alluvial diamonds deposits in the Diamantina (Minas Gerais) region. This old secondary formation is being reworked by the rivers in the area, releasing the diamonds it stores (themselves originated in primary, still unidentified, sources) into modern alluvia. Both the old conglomerate (Fm. Sopa – Brumadinho – Espinhaço Supergroup, Middle Proterozoic) and modern alluvia have been mined for diamonds since the early XVIII century in the region, in the process giving birth to diamond’s Modern Era.

Several outcrops may be visited in the area: the pictures I have included in the photo gallery are from Lavrinha (Campo de Sopa – Guinda), a short travel from Diamantina. Many other outcrops are visible in the region.
