A few months ago there were some discussions on a now defunct blog site “I THINK MINING” and on a website (https://lindsaynewlandbowker.wordpress.com) regarding whether mine environmental approvals should be linked to the overall financial health of the parent company.
This point was raised in regards to the Mount Polley tailing dam incident as well as other notable tailings failures. The logic behind the idea was that the potentially high cleanup cost for tailings failures could exceed the financial capacity of a small mining company and then the failure cleanup cost would need to be borne by the taxpayer.
Are reclamation bonds of sufficient size?
Closure bonds for final reclamation are standard practice in current permitting approvals and part of the normal course of business. However what is being newly proposed is the requirement to have sufficient corporate funds in the bank account to pay remediation costs for some hypothetical failure. This has not been part of the current environmental approval process as far as I know. Depending on the type of failure scenario one envisioned, the hypothetical cleanup cost could range from low to enormous.
A failure cleanup fund
One of the options being proposed is that the various mining companies in a jurisdiction each contribute money to a failure cleanup fund that could be used for mitigation purposes.
The ultimate goal of this idea may be better environmental practice or simply as a means to curtail mine development by handcuffing smaller companies.
Many deposits are too small for the major miners so the intermediate companies are the only ones interested in them. However if they don’t have the financial reserves in the corporate bank account, then their projects would not get approved.
Small companies would only be explorers
Mines require the capacity to cover unexpected costs. There are a number of ways to do that, including having the money in the bank or a letter of credit, which is essentially an insurance policy. But for how long? Should the money remain on account forever? When is a TMF considered stable?
