RE: TPA vs Metric Tonnes15 Jul 2022 16:06
Hi Skeletor, you're correct, TPA is is 'tonnes per annum', tonnes also being written as MT(s) in reports for production and sales figures - another way of seeing this in real life is the 1MT jumbo bags miners use to fill with their product, in TGR's case Graphite concentrate, and which the company sells. 1,000kgs makes 1MT.
We have had installed capacity of 12,000tpa since December 2021. But the company has to debottlenecked and ramp up operations at the new 9,000tpa plant. From the installed capacity the company starts at about 30% production and takes 3 quarters to ramp up to steady state production capacity. As we are now 2+ quarters since December, and considering the content of the last operational RNS, I think we can expect the production and sales figures to increase towards the 2,250MTs per quarter at the 9,000tpa Vatomina plant + around 750MT per quarter out of the 3,000tpa Sahamamy plant. Of course this depends on things like weather and ability to operate at the larger scale, and actual sales pipeline, and production will probably never be 100%.
However, I actually haven't considered this latest point in much depth and realised that the highest quarterly shipment and sales of 1,137MT for Q4 (Jan-March) recorded in the operational RNS is extremely good news - it suggests that the combined operation of Sahamamy (3,000/4 = 750) and Vatomina are working at 80% of their planned output if you take into account the 30% start up rate at Vatomina (9,000/4 = 2,250 - @30% = 675) - and that is despite the terrible weather in Jan-March (max 675 @30% Vatomina +750 Sahamamy = 1,425MT. 1,137/1,425 = 79.8%).
The improved mining fleet and infrastructure should help speed up operations-ramp at all new plants. Assuming Vatomina ramp up is progressing, being conservative if we add 20% to the 1st quarter of this year (April-June) so Vatomina is at 50% we could expect something like 1,125 (9,000/4=2,250 @50%) + 750 = 1,875MTs...the same going up to 70% for July-September = 1,575+750= 2,325MTs. I have probably been over-optimistic on the Sahamamy 750MT figure each time, but then possibly conservative on the % utilisation of the Vatomina plant in the FY22 Q1+Q2 forecasts. If we get news that these ramp up stages are being met, and if we can get to that golden 2,000MTs of sales a quarter number that will be very good. I've just pulled that number of the air as don't know the exact number we need to hit net profit, but it seems like a good place to start.
To your original question, essentially like all mining projects while we have the capacity installed, it takes a little while to get those operations running at full speed from the moment they commission. From the prospectus they anticipated 3 quarters to get the 9,000tpa up to speed and anticipate only 2 quarters for the first new 18,000tpa module based off lessons learnt.
Hope this and my side discussion is somewhat helpful
