why CYM is a Billion $ company in the making, page-260

CYM HL retreat – Dig up the existing HL/tailings material and send through the crusher to uniform material size. Reset the leach pads with appropriate piping and IP setup and start leaching. Benefit on not having to blast, dig and haul material from 100-200m down in the open pit. You only have to move the material a short distance to the crusher and back. So therefore far cheaper input costs. Tailings underwent trenching and drilling to substantiate an approximate percentage of contained copper but due to inconsistent size and grade difficult to ascertain exacting numbers.(It’s not a naturally structured ore body with a classic assumed level of known confidence, hence does a JORC code even apply?No.)

Expansion of the Nifty pit. Just need to widen the benches as you go down so relatively cheap way to expand the mining pit as you continue to strip the higher grades already exposed in the pit. Downside to this is that there is likely more overburden to move in the initial years so likely later on the tailwinds of this process will shine through for CYM when they reach the higher grades down low. But because of depth of pit you have extra haul costs associated so this may even out results over LOM

My understanding is that the EW uses several tanks. I believe 4 in total which means if you added another tank for the sulphide solution you could increase the output. But the limitation of that is the electrical power output of the 21MW gas/diesel turbine power plant. The generator also runs the camp so you would assume there is some leeway of available electricity. So could another module be fitted to the 21MW generator? Perhaps but maybe better to wait for Nanadie Well to commence and focus time and $$ on that.

But let's not forget the 2.8Mtpa concentrator was in use by Metals X. Metals X placed Nifty into Care and Maintenance in Nov 2019.
Last concentrate shipment was for 4,974t of contained copper in Dec 2019.

This is what I don’t get. It seems CYM is being valued like an explorer. Currently the MC is totally non reflective of CYM possible earnings and closeness to production.

Barry could start producing via the concentrator in the near term and sell that to create cashflow while the heap leach pads are moved and repositioned to produce copper plate by Q1,2023. Or is a matter of finding available time to use the crusher circuit as the HL retreat also needs to go through the crusher to obtain uniformity of material. Perhaps this is one area where the market is vexed currently about the methods and stage to production.

Here are some interesting titbits worth noting;
From the 11th June 2020 Metals X Nifty open Pit Scoping Study
At the assumed long term copper price of A$8,500 per tonne 2(US$2.62/lb), total pre-tax net cash flow of $405 - $435 million, pre-tax net present value (10% discount rate) of $170 - $190 million and a pre-tax internal rate of return of 50% - 54% for the open pit sulphide operation. All-in sustaining cost (AISC3) of approximately $5,400 - $5,800 per tonne of copper produced (US$1.67 - US$1.79/lb). calculated at $0.68 USD/AUD

*It is assumed that the oxide ore is delivered to the heap leach pad location at zero cost given the alternative is to a location adjacent to the open pit waste dumps.
