Nzega Property
Summary & Overview
- The project area is ideally situated within the western and central parts of the Nzega greenstone belt. One prospecting license lies to the W of the Golden Pride mine (Resolute) while another is situated immediately to the N of the Golden Pride mining lease boundary. The E-W trending Nzega shear, which is believed to be an important structural control at Golden Pride, also cuts through the project area.
- The area is largely covered by mbuga, with outcrops occurring on the hills. The dominant rock types are felsic volcanics and BIF, with subordinate mafic volcanics and sedimentary rocks.
- Grab samples collected near old artisinal and mine workings report encouraging values of up to 3.9 g/t Au.
- Geological mapping and a shallow drilling program have been planned for the entire project area. In addition to gold, heavy mineral separates will be analyzed to determine any kimberlite potential.
Regional Geology :
The Nzega project area is strategically located at the western and central parts of the Nzega greenstone belt, proximal to Golden Pride mine (Resolute; 2.7 Moz @ 3.0 g/t Au). The dominant rock types are felsic volcanics and BIF, with subordinate mafic volcanics and sedimentary rocks. Though principally a gold hosting area, numerous recorded kimberlites do exist, and the project area does fall within the diamond corridor. Numerous aeromagnetic anomalies on Tan Range ground will warrant further follow-up.
Principal Structures :
The Nzega shear zone is interpreted to cross the project area in an E-W arc, extending from the SW corner (Chambo), passing just S of Golden Pride mine, and continuing E to Sekenke, across the rift valley. Secondary NW-SW trending shears have also been modeled for the area. These structures are interpreted to represent key controls on gold mineralization in the Nzega area as a whole.
Geology of the Prospecting Areas :
One license is mainly covered by sandy soils, red brown lateritic soils and mbuga. Outcrop is restricted to the hills, consisting mostly of BIF (with sporadic interlayers of chert) and felsic volcanics. An old small-working (Mahane) is located in the NW of the license, and is characterized by thin shears trending NW-SE, with steep dips both to the N and to the S, within a BIF/chert host. Old artisinal workings can also be found to the SW of the license.
One recently acquired license consists mostly of greenstone, with a N-S trending mbuga cutting midway through it. No geological mapping has been undertaken as yet. Three aeromagnetic anomalies require testing for their kimberlite potential.
Exploration Completed
Geological mapping, grab and termite mound sampling (October 2004). A total of 113 grab and 10 termite mound samples were collected. Assay results returned anomalous values of 0.19 g/t Au, including a single peak value of 2.59 g/t Au. Most anomalous samples were collected from an abandoned artisinal mine to the SW of the license. Grab samples collected from the old Mahane workings returned values of ~1 g/t Au from BIF/chert outcropping adjacent to one of the shafts, and a result of 3.9 g/t Au was obtained from a trench exposing sheared BIF/chert, proximal to the workings.
Hand-auger soil sampling program (October 2004), consisted of some 23 holes being drilled, of which only two holes intersected bedrock. Assay values lie between 0.002 and 0.003 ppm Au, with a peak value of 0.011 ppm Au.
Biogeochemical sampling (November 2004) has been completed. Detailed analysis and interpretation is pending.
Aeromagnetic interpretation did recognize 3 potential kimberlite pipe targets, which still need to be evaluated. No groundwork has been undertaken as yet.
Geophysics:
The area has been covered by airborne geophysics (West German 1987 program, and Geodass 1999 program).
Future Activities
- Review the biogeochemical data.
- Shallow drilling over areas covered by mbuga, to asses both gold and kimberlite potential.
- Detailed lithological and structural mapping of old artisinal and small-workings.
- Shallow-drill geophysically derived kimberlite targets.
