General:
- 60 km combined structural strike length
- Structurally controlled vein- type deposit
- Gold in quartz- hematite veins hosted in sandstones/ shales
- Geophysics, particularly electro- magnetics, indicates further prospective zones within the license area
- So far, approximately only one third of the prospective area has been visited and sampled
Exploration Results:
- 45,000 individual geochemical data obtained, 58 elements analyzed
- 23 significant gold anomalies
- 20 significant palladium anomalies
- Significant anomalies for rare earths, lead, zinc
- 4,000 fire assay data
- Fire assays (1m channel cuts in trenches) confirm geochemical anomalies
- Each tested geochemical gold anomaly shows several g/t in shallow trenches
- Strongest geochemical anomaly shows several fire assays above 140 g/t, numerous values between 20 and 70 g/t within other anomalies
- One mineralized vein was followed over a strike length of more than 1 km, indications for a total strike length of more than 2km (trench sample results of up to 32 g/t)
- 16 drilling targets identified so far with gold MMI (Mobile Metal Ion) response ratios between 10 and 110 times the background value
Results within Mining Lease:
- Trial mining at two hills within the mining lease confirms sampling grades obtained by fire assay
- Structural control clearly identified at the two main zones within the mining lease
- Sampling of an adit (approx. 20m below surface) at one of the hills shows two mineralized zones. The first zone averages 8.4 g/t over an apparent width of 9m, the second averages 4.7 g/t over an apparent width of 7m. This second zone was not intersected completely with the adit end face assaying 2.7 g/t
- Current trial mining from surface above the adit within the first zone only has exposed two pay structures to follow. The one shear zone averages approx 8g/t over 2 metres (up to 60g/t in a 1m cut). The other multiple veins zone is expected to yield stoping grades of approx 5g/t over a 4 metre width at the original adit elevation
- The second hill shows up to 4 reefs, the highest near- surface value is 147 g/t (1m channel sample cut in a shallow trench) with further values exceeding 20g/t at various points along the new access roads cut into the sides of the hill
- Sampling of quartz- hematite veins in the valley shows several g/t Au. This confirms indications from the electro- magnetic survey some of the low lying areas carry economic potential. So far, only the morphologically exposed areas were tested in detail
- Trial mining of the free dig alluvial gravels (2.6m thick layer) in the valley has given an average calculated grade of 0.63g/t over 4,300t mined to date
- Panning of the free dig alluvials in the valley continue to show speck counts of between 15 and 45 per pan which relates to grades of approximately 0.4 to 1.2g/t
Genetic Indicators:
- High iron oxide content in both veins and host rock
- Geochemical data indicate a hydrothermal fluid mix derived from both felsic and mafic magmas (tungsten/ heavy rare earth anomalies et al.)
- Gravity high in central sedimentary area
- Target areas are sandwiched between two granites, there are indications for andesitic/ basaltic volcanics below the sediments, ultra-mafic dykes within the mining lease
- Indications for an IOCG-type mineralization
- The age of the mineralisation is palaeo- proterozoic (approx. 1,600-2,500 million years ago), one of the most promising eras for large multi- commodity deposits
- License area is within the “Circular Dyke Swarm”, a large regional structural feature connecting the Tanzanian gold fields with the Kilo gold fields in the DRC (“Kilo- Geita trend”)
Geological Survey:
- The mine is in good standing with the Department of Geological Survey and Mines (DGSM). The DGSM is both the licensing (exploration licenses and mining leases) and controlling authority for all mining related activities.
- The World Bank and the Nordic Development Fund sponsored a major project aiming at both improving the geological data base of the country and re- equipping the facilities at the DGSM.
- Part of the project was an airborne geophysical survey which covered the mines license areas, providing excellent results
- Recently The Finnish Geological Survey (as part of the project) conducted a mapping and geophysical training programme for the DGSM within themining lease
- Further programmes will be conducted in and around the mines licenses/lease.
Resource Potential:
- Potential for multi- million ounce gold deposit
- Economic potential enhanced by possible by- products (palladium, rare earths, lead, zinc et al.)
- Trial mining confirmed the adit mineralisation continues up- dip with two pay structures, one being a shear zone and the other consisting of a series of quartz-hematite veins dipping at around 60° in a westerly direction. Both these pay structures are expected to continue in depth below the adit
