Expert David Bembeja, a geologist and managing director of Machimbo Explorer, has emphasized the importance of conducting scientific surveys before mining begins. Speaking at the ninth National Mining Technology Exhibition in Geita, Tanzania, on October 2, 2026, Bembeja noted that some miners invest heavily in extraction without adequate surveys. This approach can lead to significant financial losses. Bembeja's comments highlight the need for a more informed and strategic approach to mining in Tanzania.
Bembeja explained that mineral exploration involves various types of surveys, including geological, geochemical, and geophysical surveys. The type of survey used depends on the characteristics of the area and the minerals being targeted. These surveys provide crucial information that helps investors determine the potential of an area and make informed decisions about whether to proceed with mining activities. By doing so, investors can avoid costly mistakes and optimize their investments.
The surveys conducted by Machimbo Explorer involve a thorough assessment of a client's licence, coordinates, and available historical information. Based on this analysis, the company recommends the most suitable survey approach. The findings help clients decide whether to proceed with further exploration or stop investing in an area with limited potential. This approach enables investors to make data-driven decisions and manage their risks more effectively.
Bembeja also urged the Ministry of Minerals to establish the Board of Geologists, which would ensure that geological work is carried out by qualified professionals and meets required standards. He warned that inaccurate geological reports prepared by unqualified individuals could expose investors to financial losses. The establishment of the Board of Geologists would help maintain the integrity of geological reports and promote best practices in the industry.
Omega Nziku, chief executive officer of Machimbo Explorer, highlighted the role of technology in preliminary exploration. She noted that information obtained from initial surveys guides the use of diamond drilling and reverse circulation (RC) drilling for more detailed exploration. This approach allows investors to make informed decisions based on better information, helping them control costs and optimize their investments.
The ninth National Mining Technology Exhibition in Geita brought together experts and stakeholders from the mining industry to discuss best practices and new technologies. The event provided a platform for companies like Machimbo Explorer to showcase their expertise and services. By sharing knowledge and experiences, industry players can work together to promote sustainable and responsible mining practices in Tanzania.
The importance of scientific surveys in reducing mining losses cannot be overstated. By adopting a more informed and strategic approach to mining, investors can minimize risks and maximize returns. As Tanzania continues to develop its mining sector, the adoption of best practices and new technologies will be crucial in ensuring the long-term sustainability of the industry.
