The consideration for the acquisition is cash payments totaling CDN$475,000 and exploration expenditure totaling CDN$1,000,000. The Optionor retains a 2-per-cent Net Smelter Return Royalty of which, 1-per-cent can be purchased for CDN$ 1,000,000.

Cash payment schedule:

The Negero Project is located within the Neoproterozoic domain of the Mozambique belt, a potentially overprinted Greenstone - hosted gold terrane in northeastern Tanzania. The Mozambique belt is characterized by the occurrence of abundant high pressure - temperature (P-T) granulite-facies rocks including granulite, mafic - to ultramafic intrusions, granite gneisses and quartzites.

Small scale gold mining within the Project area has exposed quartz vein development and prominent potassium feldspar alteration within wallrocks, which include amphibolite and saprolite. Airborne geophysical data over the area shows significant structural development on both a NE-SW and NW-SE trend, similar to that of the nearby Canaco Resources' Magambazi Hill Project. Grab sampling from metasedimentary outcrop, near the small scale mining area, returned assays values of up to 31.9 ppm gold (Au).

The location of the Negero Project within a potentially overprinted Greenstone Belt, the presence of crustal scale shearzones and nearby felsic intrusions provides significant potential for gold discoveries. In addition, the similarity in geological - and structural setting to that of nearby Canaco Resources' Magambazi Hill Project, provides additional potential for gold exploration on the Negero Project.
