My MRE26 Jul 2020 14:14
Hi everyone – first post so be kind. Holder since June 2018. Built up to 1.1m holding at average 2p so very happy with current SP. I’m a keen follower of this board and value the knowledge and enthusiasm shown. Newcrest’s Exploration Update inspired me to carry out my own Maiden Resource Estimate.
I visualised a very simple 3D model of the resource based on the images on Page 5 and the Legend in Fig 2 of the Update. Assumptions are:
• The implied continuity of the deposit to the NW to form a continuous elliptical deposit is true.
• Ore structure is an elliptical shaped elongated doughnut 630m deep which tapers in cross-section top to bottom.
• The core of the doughnut is the sulphide ellipse, 20m thick, which is 550m (SE to NW) by 320m (SW to NE) at the top tapering to 200m by 320m at the bottom.
• Sulphide vertically divided into three zones: upper 230m @ 5g/t, middle 200m @ 4g/t, lower @ 3 g/t.
• Sulphide doughnut is surrounded by an inner Breccia zone (@1g/t) and an outer Breccia zone (@0.5g/t). Each Breccia zone is 2x20=40m total thickness.
• So the overall doughnut thickness is 100m.
• I reduced the volume by a vertical slice 35m wide representing the post mineral dyke.
• Ore density 2.8 t/m3.
On that basis my spreadsheet gives a MRE of 50 million tonnes of ore containing approx. 8 million ounces of gold (overall average 1 g/t).
My feel is that the dimensions and grades assumed are on the conservative side and so this MRE probably lies in the lower end of the range of possible answers. Referring to Investor Journey’s ‘GGP Stock Analysis (22 June)’ with an assumed gold price of £1750/oz and an 8m oz reserve a fair SP is 37p (AISC = $912). His analysis makes an allowance for the associated copper value though I haven’t made any assessment of Cu resource.
This back of fagpacket calculation ignores any further expansions of Haverion currently being investigated by Newcrest and any value attributed to Scallywag etc. On this basis I’m more than happy that the SP has some way to go.
