PERTH-based Castle Minerals has discovered significant gold mineralisation at its new Kpali prospect in northwest Ghana.
The company reported that rotary air blast drilling successfully identified a 650m-long continuous zone of near-surface gold mineralisation containing 7m at 1.20 grams of gold per tonne, including 2m at 2.13g/t of gold from 20m, and 5m at 1.32g/t of gold from 6m. vReverse circulation drilling only tested the southern 200m of the 650m-long anomaly.
Castle Minerals managing director Mike Ivey said the Kpali mineralisation would be included in the geophysical survey for its high grade Bundi prospect.
“This work confirms Kpali as an exciting new gold discovery for the company with our strong expectation that we will define a significant gold resource following further drilling,” he said.
Kpali is 4km south of Bundi and has similar rock formations but does not display the high zinc and base metals association seen at Bundi. The proposed next steps include airborne geophysical surveys and extensive reverse circulation drill testing.
Exploration drilling at the Bundi project recently defined a high grade gold and zinc horizon across an 1100m strike that significantly upgraded its resource potential.
“This is a very positive outcome for Bundi; the horizon identified may represent the distal portion of a volcanogenic massiv sulphide horizon and provides considerable scope for the definition of a high grade gold and or zinc deposit,” Mr Ivey said.
Castle is the sole operator of the 10,000 square kilometre Wa project which includes the Bundi and Kpali projects as well as the high grade Julie West gold corridor.
