Nyanzega N. Property

Nyanzega North Property

Summary & Overview

The project area is some 40% covered by mbuga, and is situated proximal to the highly prospective "Nyanzaga-Kitongo-Luhala Corridor".
Principal rock types include granite, greenstone and granodiorite.
A major WNW trending shear is located towards the northern part of project area. Mineralization appears to be associated with this shear, within a granodiorite host.

Regional Geology :

The property is situated N of the "Nyanzaga-Kitongo-Luhala Corridor", which forms a link between the Geita greenstone belt to the NW, with the Buhungukira greenstone belt towards the SE. The Kitongo project (Gallery Gold) has a published resource of 0.48Mozs @ 2.0g/t Au. Principal rock types include granite, greenstone (chert/rhyolite) and granodiorite.

Principal Structures :

A strong NNW trending lineament transects the central portion of the project area, and is interpreted to represent a second-order shear joining two first-order ESE trending shear zones: the first defines the structural contact between the greenstones and the northern granite, and the second regional shear occurs some 12km to the south of the project area, and is closely associated with mineralization at the Tusker and Serengeti prospects (Sub-Sahara Resources).

Geology of the Prospecting Areas:

The northern 40-50% of one license is underlain by coarse-grained granite. These rocks outcrop E of the license and have been interpreted to extend NW along a structural contact. A central band of greenstones, principally chert/rhyolite, crosses the license. The SW corner of the license is underlain by the Nyaruhwa granodiorite, which has a distinct texture that sets it apart from the granitic rocks that occur to the N and to the W.

Mbuga covers ~40% of one license area. The area is underlain mainly by granite in the N, and granodiorite towards the S. The principal NW trending shear structure, which occurs in the central portion of one PL, projects through the northernmost part of this license.

Reconnaissance Sampling:

Mini BLEG soil sampling (November 2003), along a 100m x 100m grid, was initiated in the SW portion of one license where lateritic soil and scattered granodiorite outcrops occur. A total of 68 samples returned anomalous values of ≥21ppb Au, with a maximum value of 170ppb Au. The soil anomaly has a general NNW trend with a strike length of ~1km and maximum width of ~600m.

Hand auger soil sampling (November 2003). A single sample returned a value of 330ppb Au in the top meter of the hole (laterite rubble zone), and 42ppb Au in the last meter (3m depth). This hole was drilled in the SW portion of the license, where a high soil anomaly was identified. The remaining samples assayed ≤2ppb Au.

Hand auger soil sampling follow-up (February 2004), most of which were taken within the BLEG soil anomaly area, returned anomalous values ≥20ppb Au with a peak value of 425ppb Au.

Trenching (July 2004) over an auger hole anomaly, achieved a single peak value of 0.29ppm Au, which occurs in a sheared granodiorite. Soil values from the trench are all high (56 to 120ppb Au).

Biogeochemical sampling

Hand auger soil sampling (September 2004), intersected granite saprolite. Only a single sample returned a value of 0.001ppm Au, with the remainder returned values below the detection limit.

Grab/termite mound sampling, all returned Au values below the detection limit.

Biogeochemical sampling
Geophysics:
The area has also been covered by airborne geophysics (West German 1987 Programme).
