Roundtable Discussion; The Future of Mineral Sands. Watch the video here.
Another thought, Hydrogen -
If I follow your theory correctly : The violent activity was perhaps more pronounced in the NW, so upsetting the antiform structure futher and even leading to a major vertical offset. Perhaps also, we can hope that the mineralisation continues further NW, so that end of Havieron makes an even larger contribution to the whole.
Thanks, Hydrogen -
This is all very interesting.
Initial investigations, I remember, suggested that the deposit(s) plunged steeply to the SE. That led to extensive drilling in the SE crescent, which goes deep as we have seen.
That was where I became confused about what could be found in the NW, as the geophysics almost read as though that was the shallow end of the deposit.
Now the breccia zones appear to be very extensive and nicely on a NW-SE trend, in line with our licence blocks. Also, although some of the copper grades are low, the copper seems to be always there, with the gold, as Magictrades said. That must be a consideration, when the economics of the breccia are considered.
If the MRE is put back, it will be for a very good reason.
Hi, Hydrogen -
I am still trying to understand the implications of the geophysics results, from our early exploration, on the GGP website.
They refer to a 200m. lateral offset and a huge 500m. vertical offset between two recorded bodies. The plan shows a large gravity response, with areas in the NW and SW which have possibly been explored by recent drilling.
I haven't seen anything in the drill results (YET), which explain a 500m. vertical offset between two bodies.
Where do you think this may be leading, please ? Are they suggesting there may be Havieron 2, below Havieron 1 ?
Paddy -
I know I have mentioned it before but, with talk today about Telfer Deeps, I was reminded of the geophysics, on the GGP website. There is a description of a lateral offset and a considerable vertical offset of two bodies, indicated at Havieron.
NCM are certainly interested in the SW and, for whatever reason, there seems to be a considerable distance (on the surface) between the drill collars and where we anticipate there may be an extension to the horseshoe arms.
So, perhaps they are drilling very deep and still investigating the indications from the geophysics.
WelshFalcon -
I agree with you. I think that NCM are in a very good position with Havieron, while working through the stages to an even better position soon.
It could also be partly a defensive move, as Schlemiel suggests.
Thanks, Hydrogen -
Yes, I was getting the different methods of gold deposition mixed up.
When I look back at our early days at Havieron, it does make me wonder what will emerge in the next 12 months.
Then we may have Havieron North, apart from the potential in our 100% - owned targets.
Hydrogen -
I think, in replying to Paddy a few days ago, you said that you looked on Havieron as a weathered anticline.
Have I understood correctly, that sometimes weathered gold falls lower into the deposit?
We also have a transition from the sulphide zone in the SE, where there is more brechia at depth and perhaps these various brechias join up, possibly at great (next generation) depth, unfortunately.
Magictrades -
Thanks for referring to the Geology and Mineralisation section of the Artemis ( Armada, Paterson) report.
I like this: "The interference of these fold patterns in the Lamil Group rocks formed doubly plunging domal structures characteristic of the Telfer district."
We are learning about the steep plunge in the SE, at Havieron. Let's see what she has been hiding in the NW !
Yes, thanks for that comparison, Paddy.
I love to see such persistent activity, over a rapidly growing area of Havieron.
If they are drilling deeper, and keep finding more, then it is a rapidly growing volume at Havieron.
Let us hope for lots more, cumulative, results and perhaps a revised 3D model.
Thanks for the update, Paddy.
I like the roadway, curving around in the north-west , just off the edge of your overlay.
I think NCM are showing us that their hopes are the same as ours, that the horseshoe will soon become an ellipse.
Thanks Lanchrishire and Rainbowsend -
The job advert. appears to read as though the decline and its boxcut have now been planned
So, NCM shareholders should soon be given details, hopefully in the Quarterly Report.

I found the videos of Cadia to be a revelation in modern mining methods, with the automation and the central conrol room.
I am sure that NCM will work as fast as they can, but safety will be the most important factor, as you mentioned.
The different types of extraction would all involve setting charges and blasting, so work in tandem would have to be carefully co-ordinated. I was very impressed, though, with the use of automation in the most dangerous areas, as in setting charges and removing ore.
Thanks for the second image of the geophysics, Paddy.
That one makes me think, wow!! We thought that the original ellipse of Havieron had great potential.
Now, we also have the mystery of the south-west, with Tig's friend and his earth-moving contract.
PLUS, whatever is being investigated approx. 800m. to the north!
Thanks for putting up that data, Paddy.
From the map of the geophysics, I am wondering if exploration at Scallywag will eventually lead us back , south-east, to the ground immediately south-weat of Havieron. I know that is a fault line that has greatly interested you.
If these areas are mineralised, it may be not where do we start, but rather where do we stop drilling.
I think a 250 man camp can provide a workforce for more than the existing Havieron drilling (and even the construction of a decline).
