Drill spacing will need to be reasonably close to announce a JORC figure. They could say they have every indication of a 150 million tonne resource. I am not sure at what distance the drill holes will be from each other. I imagine they would do most drilling in that northern ridge area if they want to come up with the highest grade and get an idea of depth of DSO and be able to give out a JORC inferred resource. The closer they drill the holes,the more certain they will be of having a winner.
To drill the same area as at Mbarga at 200mt x 200mt,they would need to drill around 176 holes.At 200 x 100 around 336 holes and so on to get to a reserve figure. For a Reserve figure I think they have to drill 50mt x 25mt. Could be 25mt x 25mt.
Avima I believe has one hole that has DSO at around 180mts or more deep and still open at depth. They should be able to drill more then 30 holes by June with two drill rigs I would have thought. The main area of Mt Nabeba looks to be a larger area then Mbarga.There are indications it could be deeper for DSO and higher grade iron ore.
