RE: We've got a road map17 Nov 2022 13:56
I just pot these days as a hobby tbh, all genuine shareholders already know most of what i post, i simply keep facts circulating to counter the green box nonsense.
How do they figure this part of a DFS out? Oh that's right, pit optimisation -
"Definitive Feasibility Study for its Nolans project in the Northern Territory forecast average annual production figures of 4,356 tonnes of Neodymium-Praseodymium oxide and and 135,808 tonnes of merchant grade phosphoric acid."
......
For a greenfield site, these questions may include:
What is the ultimate pit limit?
What capacity should the plant be?
Is it worth acquiring a neighboring lease?
What should internal phases look like?
Alternatively, for a brownfield operation, the questions may be:
Are the existing phases still valid?
Should one mining area develop before another?
Will capital expenditure to increase mining rates add value to the mine?
While these questions are not unsolvable, they are complex and involve many stages of problem definition and analysis.
The industry’s go-to method
The current approach to solving these problems involves a mixture of optimization techniques and heuristics. This approach consists of three primary steps:
Find the ultimate pit limit
Select internal phases
Determine mining and processing schedules - ****the processing schedules to feed the plant that Sinosteel (or someone else) will build
After selecting the ultimate pit limit, revenue factor shells from LG or Pseudoflow algorithms are generally used to determine candidate shapes for internal phases. Phase selection is a highly iterative process considering items like operational geometries, total volume, and ore delivery to processing.
