Ann: $10m institution led raise to accelerate and expand drilling, page-677

Rally,

First pass is always surface to 150m deep Max on an outcropping system.

Generally we drill 45 Deg and across an ore body.

If first drill intercepts, then another, generally under and parallel to the above hole.

If the second hole intercepts same width or wider than the above hole 1.

We know ore body is widening at depth and open in depth.

We can then go with another hole, under hole 2, or move the rig, 100m along strike and repeat the process.

Continuing along strike till NSI.

Once that is done, we have a closed strike length, and open depth.

Then we go back and drill a deeper layer.

It is critical to understand Geology in layers and over distance.

It is why you would not sit in one spot and drill deeper and deeper.

For example if a secondary lode is 100m down strike, it might get missed and more work if a deeper prior hole had to extend a short distance to intercept secondary.

So going back deeper, takes into account structure either side from prior drills and covers the above.

Here going deeper means they have drilled, got intercepts that widen at depth and open.

If not open or orebody narrowed, you would not drill deep.
