Golden Rim Resources (ASX: GMR) has discovered a significant new zone of gold mineralisation in trenching at the Linnguekoto Prospect in the Sepola Project, western Mali.
Channel rock chip sampling of trench two has provided an intercept of 16 metres at 3.15 g/t gold, including 1m at 17 g/t gold, with the mineralisation hosted in a quartz diorite intrusion.
If the intrusion is found to be extensive, potential exists for large volumes of gold mineralisation to be delineated. Very large intrusion-hosted gold deposits have been found elsewhere in West Africa.
The company's next phase of exploration will determine the extent of the intrusion and include further trenching and reverse circulation drilling.
Gold mineralisation has been located in all four trenches completed, although trenches 1, 3 and 4 did not intercept the quartz diorite intrusion and gold results were lower.
The new zone of gold mineralisation is located 1.6km south of an area of intense artisanal mining where very high grade gold-bearing quartz stockwork veining is being extracted from a series of shafts.
Golden Rim rock chip samples of this veining have returned assays up to 1,205 g/t gold. Previous drilling in this area has returned intercepts of up to 18m at 8.19 g/t gold.
