Need to filter if you don't want to get drowned out...

I see that we still get a 'message filtered' notice, but at least it is green so more asy to find real posts

Many thanks Shorn.
Done
But I guess we will have to do it for every login name used in order to avoid being swamped like last night?

I have never filtered anybody before, but it may be necessary to avoid disruptions by this quadbot person- how is it done?

Hello Ella,

Perhaps it was 1% of Cu equivalent as grades are usually expressed that way for copper properties?

Incidentally,

Anybody that was surprised by yesterday's RNS should read my post at 12.52 on Jan 21st - it wasn't rocket science...

Hello BH,

Funny you should say that.

I have thought it odd that every RNS states that we are taking hand-held assays of the copper present in the cores, yet we have only been told that the initial mineralisation was in excess of .3% and the tail- off at the end of the drill averaged around .55%
I is highly unlikely that readings have not been taken throughout the drill, including the "beautiful" 300m high-mineralisation section.

Why have these intermediary grades not been reported?
Could it be that the readings seemed to be unrealistically high and that an expert opinion was needed to determine if some other anomaly was responsible for the results before revealing them to the market?

Maybe, or maybe not, but I can't come up with a better explanation - the Geo report next week should reveal all...

Stroke = strike

Hello News,

I agree, the original strike length of 1000m was based on relatively shallow drill holes.

Now that we know the depth goes to at least 1100m then the stroke length could well be revised...

Hello Ella,

That is my understanding.

Of course the cut-off grade of the mineralisation will also be important and that is one of the things we hope to confirm with our drill programme - both for copper and for gold, the latter of which was largely overlooked in the original study...
Should be an interesting week or two.

Hello Shorn,

Again I agree and they will probably have to carry out two or three drills at each level, from different directions, to build up an accurate 3D picture, but like you I am not an expert, so am happy to defer to those that know better.

One thing is for sure, the current drill is very important as it will set the stage for the others that are to follow...

I agree Shorn.

The original drill was at 50 degrees to run down the central core, so one offset and drilled at 40 degrees should enter the side of the porphyry and meet at 90 degrees to the original drill ( perpendicular, as described by CB.)

As the mineralisation started at 110 metres, I would guess the new drill will be offset so as to intersect well into the mineralisation zone, so there will be about 200m of drilling before entering the side of the porphyry and still another 500m available to test the width (diameter). So if the diameter ends up being more than 500m then they will need to continue drilling until mineralisation Peter's out.
I think it unlikely that the width will be more than 500m as that would indicate a maga structure and that is why, IMO, they have decided to limit the drills to 700m.

At a drill rate of 100m per day it will not take long to confirm one way or the other - initial update on Wednesday and final one on Friday perhaps, unless something happens to reduce the drill rate?

Agreed, we have two variables left in the equation - diameter and grade. I thought it would be fun to work out the effect on tonnage so that we can extrapolate the data as it comes back from site.

The density of quartz is 2.65 and of chalcopyrite mineralisation is 4.19, as mineralisation is continuous and is accompanied by quartz the overall density would be around 3 - so let's say 3 tonnes per cubic metre.
I think it would be interesting to see just what difference the grades would make to the overall tonnage of copper in the porphyry so I will do a few calculations over the weekend and post the results if anybody is interested.

Mever seen a spam.lile this?

Please report and have removed

I just listened to CB's latest podcast - does anybody else think he has been celebrating?
I can normally understand just about everything he says, but not today...

Many thanks for the explanation, Frog.

Hello Frog,

I am not an expert, but if there is 65m of mineralisation from799m then that wold take us to 864m, so it is difficult to understand how there can be different grades from 838m? - unless it is done on averages, in which case there would have been virtually nothing between 799m and 838m?
Happy to learn where I am going wrong...

Hello News,
I remember CB saying in one of his interviews that he thought, from the core samples he had seen, that the hole was being drilled to one side of the central core rather than down the centre. That, together with the inevitable deviation from the drill line as the length of drill increased and the rock became harder (deflecting the drill bit?), would add up to the distinct possibility that we came out of the porphyry early.

I think that is why CB may be thinking he needs to add a drill or two to the first phase to firm up the 3D shape and dimensions - that could also be a reason why he went for a placing sooner than originally anticipated?
