Awuoro, Kanga and Kwoyo Areas


Stockport's initial exploration program has focussed on gold in the Awuoro, Kanga and Kwoyo areas of the SPL 258 concession located in the north-eastern area of Stockport's Nyanza Project.

A corridor of gold-in-soil anomalies (up to 1,150 ppb Au) in the Awuoro-Kanga area, extending over an area approximately 7.0 km in length by 1.0 km wide, culminates in a 1.5 km x 1.0 km roughly circular area of anomalous gold-in-soils (up to 2,530 ppb Au) and artisanal workings that returned chips and grab samples of up to 37.8 g/t Au. These showings are distinct in that the gold is contained in vuggy, high-sulphide quartz veins, hosted by felsic volcanics with interbedded BIF, and exhibit a more "epithermal" geochemical signature (Ag-Pb-Zn-As-Sb). Preliminary drill results have shown that the soil anomaly and poorly exposed stockwork quartz veins are associated with underlying hydrothermal intrusive breccias. This style of mineralization is distinct from that in the Kamwango area, where mesohermal-style gold mineralization is associated with sheared basalts.

On the Kwoyo grid, located to the NW of the Kanga area, preliminary ground follow-up of a large (2.5 km long) Au-As-Sb-Cu-Zn soil anomaly has discovered that the anomalies are generally underlain by a large banded iron formation ("BIF") sequence. At the Kowyo East target, the Au-in-soils appear to outline a folded BIF, where associated quartz vein rubble was also discovered. At Kwoyo West, the BIF also has a strong Cu-Zn soil anomaly, suggesting there may be additional potential for VMS-type mineralization

Together, the soil and rock data from the Awuoro-Kanga and Kwoyo areas, on the SE portion of the SPL 258 concession, appear to be outlining several sub-parallel major auriferous structures that extend over at least 12 km in strike length. Ground geophysical surveys have helped to establish portions of the structural trends, and areas of potential mineralization around the former "Colonial-era" and recent artisanal workings. Although detailed records are scant, based on contemporary descriptions by mappers of the Kenyan Geologic Survey, the "Colonial-era" mines within SPL258 were generally limited in scale, following individual high-grade quartz veins to a maximum depth of approximately 5 to 25 metres.
