RE:RE:RE:RE:RE:RE:RE:We will need a News Release soonQuestion: The merits of Reverse Circulation Drilling at Moroy?

A big advantage of RC is its high rate of penetration. Penetration rates often exceed 80 m per shift depending on ground conditions. The speed of drilling can often mean big cost savings compared to slower drilling methods.
From my reading of the pros & cons of RC drilling, it seems that one of the advantages is that the drill sucks up broken ore at the level of the bit.
If the drill location were found to be non productive of hi grade gold, then the RC drill could be relocated until a highly prospective location is found. In this way, could the RC drilling method be used as a pathfinder for the core drill locations to be selected.
The above sounds logical, but I am sure that I will be corrected if this were impracticle, for various reasons.
