Alecto Minerals has announced positive results from trenching and soil sampling at Gourbassi East at its Kossanto gold project.Alecto has made a swift start to exploration following the acquisition of the Malian assets and the appointment of the new chief executive, Mark Jones, last week. Gourbassi East is where the current resource is on a north north-east trend. The current exploration is on an east-west trend. Early trenching is often imperative in understanding the geology. Significantly, the mineralisation discovered in the latest trenching is different to that in the main zone, with the current gold grades associated with hematite and limonite stockworks and granodiorites. This new type of mineralisation is encouraging and increases the prospectivity of the Kossanto project.
This current resource is based on a strike length of only 500m whereas the anomaly extends the Gourbassi East main zone through a 1,000m long by 100m wide extension. Additionally, to the north there is another anomaly, much larger with a strike length of 2,500m. This has areas of higher order (+100ppb Au) plus drill intercepts. The north anomaly is around 100m from the Gourbassi East main zone and is thought to be a dislocation of the existing discovery rather than a discreet new ore zone.“This area is very prospective and the understanding of the geology is improving quickly,” says Fox Davies. “It is a known fact that a few strategically placed drill holes will double the current ore resources which also remain open at depth. With new drill targets in this very prospective area, the potential for a significant increase in ore resources over and above the current 107k oz JORC compliant resource.”
