Some thoughts on non-linear adjustments to past valuations:
1. Copper price. The value of a copper deposit is not proportional to the copper price but rather to the profit margin. If we’re comparing against a transaction which took place when copper was $3lb and we assume it’s now 4lb, it might be tempting to think we need to multiply the valuation by 4/3. But no, if we assume cost of production is $2.5lb, the margin has tripled and we need to multiply the valuation by 3.
2. Size of deposit. Total cost of production does not increase linearly with deposit size. Instead, the bigger the deposit, the lower the cost of production per pound. So if we’re comparing a historic 1MT transaction against a future 2.2MT one, we shouldn’t multiply by 2.2, but rather by a larger figure. Also, one would expect a deposit large enough to interest majors to command a premium.
3. Difficulty and cost of mining. Obviously some deposits are relatively cheaper and easier to mine than others. BR is open and economical near surface. Others may have been deeper or with more wasted mining.
These are just examples, but I do suspect that a valuation exercise which makes fuller allowance for the specific features of BR and the market conditions in which it will be sold will produce a much higher valuation
