"With the close collaboration of Dr Dominique Fournier, Vice President - Exploration for MDN Inc., we decided to model three gold signatures corresponding to the different geologic contexts present on the MDN exploration permits. Distinct gold signatures will be generated for high-grade quartz veins (Tulawaka East type), for volcanic rock-gabbro contacts, with lesser grades, (Tulawaka West style) and for mineralization associated with granodiorites (Isambara/Viyonza type)", declared Mario Justino, Manager - Geology for DIAGNOS.

In Tanzania, MDN holds a majority interest in 28 exploration permits around Tulawaka and in two other permits in the Ikungu sector, in addition to its 30% participation interest in the Tulawaka Gold Mine.

DIAGNOS can count on a multidisciplinary team that includes professionals in geophysics, geology, Artificial Intelligence, mathematics, as well as remote sensing and image interpretation. The Corporation's objective is to develop a royalty stream by significantly enhancing and participating in the exploration success rate of mining and oil and gas companies.
