To estimate the net value of 7 million tonnes (Mt) of ore at 1.3% nickel and 5 million tonnes at 7% copper after deducting operating costs and variable expenses, we need to proceed step by step:
1. Calculate the nickel and copper content:
2. Evaluate the gross value of the metals:
-
Assuming an average nickel price of $16,000 per tonne (based on available data).
-
Gross value of nickel = 91,000 tonnes × $16,000/tonne = 1,456,000,000 USD (1.456 billion dollars).
-
Assuming an average copper price of $8,500 per tonne.
-
Gross value of copper = 350,000 tonnes × $8,500/tonne = 2,975,000,000 USD (2.975 billion dollars).
3. Total gross value:
-
Total gross value = 1,456,000,000 USD + 2,975,000,000 USD = 4,431,000,000 USD (4.431 billion dollars).
4. Deduct operating costs and variable expenses:
-
Operating costs and variable expenses can vary significantly from one mine to another. For a rough estimate, let's assume that costs represent about 50% of the gross value of the metals (which is a significant simplification, as actual costs can be more or less):
-
Costs and expenses = 4,431,000,000 USD × 0.5 = 2,215,500,000 USD (2.2155 billion dollars).
5. Net value after cost deduction:
-
Net value = Total gross value - Costs and expenses
-
Net value = 4,431,000,000 USD - 2,215,500,000 USD = 2,215,500,000 USD (2.2155 billion dollars).
This estimate is highly hypothetical because:
-
Nickel and copper prices fluctuate constantly, so the figures used here are averages based on recent data.
-
Operating costs and variable expenses can vary significantly depending on the mining project, location, technology used, environmental regulations, etc.
-
Factors like metal recovery efficiency, losses, and other operational expenses (such as capital costs, taxes, etc.) are not accounted for here.
Thus, the net value of 7 Mt of ore at 1.3% nickel and 5 Mt of ore at 7% copper after deducting operating costs and variable expenses could be approximately 2.2155 billion dollars, but this estimate should be taken with a lot of caution.
