Remy already said " that is why we are going through the motions" in last conference call.
Hopefully they just get the study out soon, to anchor this SP. You would hope the consultants have agreed to prioritise it given the situation so it should be out very soon
Ploy/Back up plan/Guarantee/Plan B all makes sense to me
Personally thinks it’s a ploy, will make Anglo offer a better deal as could go alone if needed. A good hedge against a no deal
Yes,I did thanks.Phew !
I think you misplaced the decimal on your percentage.Hopefully we can do better than 0.08% :-)
@Seis 7.5mt @ .08%=6.000t or am I misunderstanding something ?
I did a rough guesstimate last night based on an average mineralised depth across the drilled area of 25m @ 0.8 % Cu.
500 x 400 x 25 = 5,000,000 cubic meters. I wasn’t sure of the rock density / specific gravity but using the figure of 1.5 gives 7,500,000 tonnes which would equate to 60,000 tonnes of Cu. (Or $600 million if you prefer!). Enough to keep the lights on anyway :-)
Try creating polygons between the drill holes based on the halfway distance between each hole and then using that polygon to give you an area for each mineralised intersection within each drill hole. You can then apply the thickness and grade to each area and use an SG of 1.5 which was quoted by NvS an Eon ago to give you a tonnage x grade figure for each polygon. It's very crude, non-Jorc compliant but it will give you an 'order of magnitude figure' for tonnage, grade and contained copper that you are seeking...
New CE plant ? ?
I was thinking more of evaluating the known deposit for the new plant at CE. Was it 300m by 500m
Not really. The extents of the ore body would need to be established first. From the drill results we have so far I would say it continues further to the north and west, and the Cu:Sc data suggests there are possibly more deposits to the south and east as well. Plenty more drilling will be needed to establish the full extents I think.
Do you have a way to guesstimate the resource based on results. I would be happy to learn more
It’s the deposit size of sentinel that makes it economical, in past would not have been mined. With modern technology is now commercially viable
F79 yes it looks like the results we’ve had so far at Cheyeza have a much wider spread of grades than at Sentinel but the average grade is similar. Fwiji is probably too early to tell with so few samples but it looks to be following a similar pattern. In the last investor call Vassilios said they would be targeting an area to the NW of the previous drills at Cheyeza, when I plotted the drill data in 3D there was one hole which didn’t fit with the rest of the band and suggested something deeper towards the west side so lets hope they hit the big sulphides on the next drill!

I know in the Sentinel modelling the cut-off grade is pretty low (0.15-0.2%), so if it was economic to mine those low grades previously how much more attractive will they be in the current market.
I would be happy with sulphides @ 0.5% but a lot of it. That’s what we are looking for a sentinel size/grade deposit.Sulphides are generally lower % but come come in larger deposits
SeizNav so my interpretation of that (if I'm looking at it correctly) is that it shows ARCM data as having more low % grades, but also more spots with higher grades that sentinel (which is encouraging).
However as ARCM have less drilling, and therefore less data points, when more drilling and results obtained the overall curve will obviously change.
Hopefully when drill at depth we will see more higher grade ores than those present at surface, and that would obviously skew the shape. Probably bringing more resource for ARCM into the mid sections of % copper.
What's your views on my thinking, and your data analysis?
Thanks
Atb
or average at that figure or better
Be happy to see oxides from surface to 100m,then sulphides from 130m to 400m. Thats enough to convince me that were getting a deal. Any grades will be welcomed above 0.75%, as long as they are continuous in mineralisation.
Now all we need is some areas to be as good as the worst at Kamoa.GLA
Thanks SeisNav.
In other words, at least as good as the best at Sentinel... That works.
I’ve done a comparison of our drill results at Cheyeza and Fwiji with the results seen at Sentinel. With so few drills at Fwiji the frequency values are a bit meaningless but anyway its worthwhile to see how the grades so far compare. Our data in orange, Sentinel in blue.
