@LongTony, appreciate your input and known you long enough to say you've got good intentions. Ive worked through possible flaws in the Coburn orebody with you before, including this post where I spilled out the usual suspects that can kill a mineral sand deposit ( ie slimes, grain size, induration, water issues, grade reconciliation... all which can impact production throughput, recoveries, operating costs, etc). You've repeated that people associated with Coburn, now and previously by the sounds, have serious fundamental reservations why the orebody is unworkable.
https://hotcopper.com.au/posts/69056164/singleSomething specific to make these claims plausible would be of great interest to the thread, otherwise your comments seem more Monday morning expert than sensible prediction. There are many reasons people may be negative on Coburn, such as very low grade, high production rate requirement, unrealistic MSP recoveries, sheet management and/or way too optimistic DFS assumptions... but those concerns are just that, concerns, not any 'facts' that make the production plan "unworkable".
We have worked through the issues as communicated by the company, including DMU production issues preventing nameplate tonnes of sand reaching the WCP (which does seem to operate at 100% nameplate throughout/recoveries over periods nameplate sand is sent to it from the DMUs). Nobody, including
@VinceS2 could explain why total 4500tph across 3 x DMUs was not sufficient to deliver 3000tph slurry to the WCP, or why 1750tph max capacity DMUs (1500tph avg op rate) were unrealistic in an industry using similar sized DMUs for over 10 years. Water issues were foreseeable and fixable, mine planning should be achievable once spreadsheet hero engineers are replaced with real-life experience (now ticked), slime and induration incredibly low (why the DFS was funded and backed by financiers and broker analysts in the first place... if the deposit wasn;t perfect for high tonne throughput it would never have got past the independent experts at 1.1% THM right).
It's all been covered to my knowledge, poor design and equipment failure is build specific and not something anyone 'knew about for ages before commissioning' . You get my point. Simply knowing somebody with a jaundiced view of Coburn doesn;t carry any weight without being substantiated having... even if their call Coburn will fail proves correct over time, so what, about as worthless that guy every Monday in the office says they called a binary footy result ...
Thanks for a bit more detail in advance, cheers."not uncommon to a new mine project finding its feet":... doesn't sound so bad they way you write it, maybe the situation is a little more serious. The new CEO is out there now looking for Coburn's feet, while shareholders administered $35M units of blood to buy time... fingers crossed
