Xtract - Racecourse becoming a little clearer.

Since my last update below. We've had the XRF results for Drill 1.  Three XRF results were taken every metre, giving what should be quite a conservative, but realistic indication of the copper. It will of course give no indication of the gold content. One take away for me is that from about 750m to 1000m, drill 1 looks like it maybe missed the exact centre of the intrusion.. This could be a step down, but might be a increase in the width...it will be interesting to see drill 3, when it crosses further down.

Back to drill 2. If drill 1 was all about the intrusion, drill 2 is all about the alteration. We know the alteration gives the greatest mineralisation at the edge of theintrusion and reduces as it goes out. For drill 2, it's about increasing the size of the mineralisation/alteration envelope within the 0.15% copper cut off or above .2% CU EQ.

There are 3 layers of alteration, the key zone, which is directly next to intrusion. The inner zone, pretty much the zone mapped in the 3D JORC modelling. The outer zone, which to this point has not been included due to the high cut off used.

So far drill 2 picked up the outer zone at about 150m and carried it to about 400m. The inner zone started around 400m and will hopefully go to 550m or so, then the key zone. Then everything in reverse.

I've included a very poor mock up of what I think it might look like and how this compares to the existing 3D model.

I've extended the inner alteration in a simple manner(green hash area), personally I think it might be wider, but would like that to be shown by drill 3.

The patchy green spray in the extent of the outer alteration zone, which will decline in mineralisation as it travels further from the blue centre. 

The yellow is there to represent the higher gold content as you go down, in what I believe is the first of several intrusion events. The first event is the gold and pyrrhotite event, the second etc the copper ones.

The important take away, is how much bigger the new mineralised system is to the old geological model that Xtract inherited.
