Yes Barras, in the near term, I think you are right.
They have been very frugal and capable of raising funds and doing deals via shares, etc.
I'm probably looking longer term.
If the whole model becomes viable due to higher Ni prices, which is possible at some stage. Then they can keep the Drill spacing down to a minimum.
If they are going to be required to chase the higher grade, whether 1% or what ever. they are going to have to generate bloke models by connecting whose higher grades together from hole to hole. This has to be shown beyond reasonable doubt, under the JORC compliance. In other words, they might be required to drill down to a 20m x 20m drill pattern, or whatever. If you look at the spacing at the moment. Lets take the 300m x 200m. At 20m space, that's 150 holes @ say 300m depth. And 300m x 200m is only a fraction of 'The Tank'.
If they can do it with RC, that will help cost. But if they have to use diamond drilling, say for navy purpose, (keeping the drill strait) then could be 5 plus times the cost.
Look at the Perseverance Shell. That will have thousands of holes in it!

Now this is way into the future. If they get to this stage. By then the share price could be back up to a healthy CR level. Plus hopefully plenty of big backers.
And really, this is all the normal process of getting a mine going. In this case. A bloody big one!
Yippee!
