1. Calculate the Gross Tonnage of Copper
Open-Pit Resource:
Total ore: 5.8 million tonnes
Copper grade: 1%
Gross tonnes of copper: 5,800,000×0.01=58,000 tonnes
Underground Resource:
Total ore: 6.3 million tonnes
Copper grade: 1.5%
Gross tonnes of copper: 6,300,000×0.015=94,500 tonnes
Total Gross Tonnage of Copper:
58,000+94,500=152,500 tonnes
2. Estimate the Gross Revenue Potential
To estimate the gross revenue, we'll use a recent market price for copper. As of September 2025, the price of copper is approximately $9,921.50 per tonne.
Gross revenue potential: 152,500 tonnes×$9,921.50/tonne=$1,512,983,750
This figure represents the raw value of the copper if it could be extracted and sold for free, which is not realistic.
3. Consider the Factors that Influence the True Value
A mine's true value is determined by its Net Present Value (NPV), which is a discounted cash flow analysis that accounts for all future costs and revenues over the life of the mine.
Here are the critical factors that are not included in the simple calculation above:
Operating Costs: The costs to mine, process, and transport the ore. These can vary significantly based on the type of mine (open-pit vs. underground), location, labor costs, and energy prices. Operating costs for copper mines can range from $3,000 to over $6,000 per tonne of copper produced.
Capital Costs: The massive upfront investment required to build the mine, including infrastructure, processing plants, and equipment. New copper mines can have capital costs of over $10,000 per tonne of production capacity.
Recovery Rate: Not all the copper in the ore is recovered during processing. A realistic recovery rate (often 80-95%) must be applied to the gross tonnes to get a more accurate picture of the final production.
Taxes, Royalties, and Fees: Governments and local communities will collect a portion of the revenue through taxes and royalties.
Future Copper Price: The value of the mine is highly sensitive to the future price of copper, which is volatile and can fluctuate based on global economic conditions, supply and demand.
Time and Risk: The project will take years to develop and produce. The value of future cash flows is "discounted" to reflect the time value of money and the inherent risks associated with mining projects, especially those with inferred resources, which have the highest level of geological uncertainty.
In conclusion, a simplified, back-of-the-envelope calculation gives a gross revenue potential of over $1.5 billion. However, the actual value of the mine would be determined by a comprehensive financial model that accounts for all the costs, risks, and assumptions that transform a geological resource into a viable, profitable mining operation. Given the "inferred" and "potential" nature of the resources, the value at this stage would be a fraction of the gross revenue, and most likely valued as an exploration project rather than
