Some numbers31 Jul 2021 11:49
Back in late winter I did some numbers to see where the BR prospect may lead the sp. I thought I'd do the same again now that the prospect looks so much bigger. One of the advantages of BR's larger size is that one can be more conservative with the figures and still end up with a valuable result. Before I start I have one question that I would appreciate an answer to if anybody has an insight. During the video/zoom meeting there were references to the very clear saddle resource to the east of the currently known resource that was picked out by the IP survey. However, this, to my eye was not clear on the 3d presentation. It looked rather minor to me but elicited a lot of excitement because what was previously dirt suddenly became 'pay dirt'. Am I missing something?
In the following, you can just inject any figure that sounds sane to you but I have tried to be conservative.
So, after watching the presentation the length of the currently planned open pit and the new IP detected area to the south was quoted as being up to 3 km long (yes, I realise this needs to be confirmed as Cu bearing ore but lets assume that's the case). So, let's use a length of 2.5 km. The width was quoted (if I remember correctly) as being over 600 m (including the saddle feature) so I'll use 600 m and a depth of 500 m as the Cu does not start at the surface. This rectangular shape has a volume of 750 million cubic metres. I'm then going to halve the volume to account for rounding off the corners of the resource and for any voids within it. Then multiply by 2.7 T/ Cubic m (this is one of the numbers we can rely on as the density of rock per Cubic metre is not going to vary too much) which gives a nice round figure of 1 Billion T.
If we assume that the average grade across the whole resource (after we have rounded off the corners and eliminated the voids is 0.002, i.e. 0.2 % then we are left with the fabled 2 million tonnes of Cu. Multiply that my 10k /T which although above the current price, is only so by a few % and could soon be a low number. Use 0.72 to convert US$ to £ and then the tricky question of the % that a miner like AA would pay for the resource. I have chosen 3% which could be very conservative considering the location of BR, the size of the resource (decades of mining to come) and the 'heat' for future Cu resources. Then divide by the number of shares which I will take as 1 Billion. The net result is: 44p per share - a ten bagger from where it currently is.
Now, many a slip between cup and lip but which of those figures would others consider extravagant? Possibly the 0.5 figure to round out the resource may be too high, the length dimensions of the resource may be too large. But many of those figures could well be too small.
Something to mull over.
