Si6 identifies new copper-silver anomaly in Botswana
Si6 has identified a new anomaly at the Dibete copper-silver prospect at its Maibele project in Botswana that has strong potential for deep-seated mineralisation.
A Pole-Dipole induced polarisation survey has just been completed following up on a recent Gradient Array induced polarisation survey. The surveys have highlighted a prominent IP high chargeability anomaly corresponding with an IP low resistivity anomaly that extends over a 2.5km strike length.
Importantly, the IP gradient data correspond well with mineralisation intercepted by drilling to date, which Si6 Metals (ASX:SI6) says warrants further work along strike and at depth.
“The Dibete IP surveys have illustrated strong target areas along strike of the known mineralisation and confirmed a 2.5km anomaly,” executive chairman Patrick Holywell said.
“Interpretation of surveys at the Airstrip and Maibele prospects are also nearing completion with results to be reported shortly.
“Planning for reverse circulation and diamond drilling will then take place.”
Previous drilling at Dibete in 2010 had returned a 38m intersection grading 1.72% copper and 119g/t silver from a depth of 16m plus other thick high grade intersections. One of the discovery holes at Airstrip returned 8m at 10.39% copper and 630g/t silver from 52m.
The Maibele project has a current resource of 2.38Mt at 0.72 per cent nickel, 0.21 per cent copper and 0.63 grams per tonne 4PGE+gold.
However, this is based on just 800m of strike that remains open at depth and along strike, meaning that there is big potential for further growth.
To highlight this potential, drilling by the company has already taken the entire strike of the Maibele North nickel sulphide body up to about 1.4km.
Maibele North nickel sulphide mineralisation is related to ultramafic intrusions within mobile belt rocks and is broadly similar in style to other ultramafic intrusion-related mobile belt nickel discoveries such as IGO’s Nova-Bollinger (ASX:IGO), Chalice Mining’s Julimar (ASX:CHN) and the globally significant Thompson Belt in Canada.
