Security and levy
Find information on the mining security and annual levy below.
You must pay a security as a condition of a mining authorisation.
A mining operator must rectify any environmental harm caused by mining and progressively rehabilitate the affected area during operation and/or once mining has ceased.
A security is a bond to make sure you meet your environmental obligations. If you don't, the money will be used to prevent, minimise or rectify environmental harm from mining, or rehabilitate a mine site.
The department sets the size of the security to reflect the potential cost of rehabilitating the mining site.
If you can demonstrate successful rehabilitation on your mining site, you may request the refund of some of your security.
How to calculate securities

You can calculate securities for the project types listed below by using the following spreadsheet-based tools:
How to pay securities
Operators must pay 100% of the security calculated for rehabilitation before a mining management plan is approved or an authorisation is issued.
You can pay the security by cheque, money order, direct debit, credit card or bank guarantee.
To pay by cheque or money order, you must make it payable to the Receiver of Territory Monies (RTM) and post it to:
Department of Industry, Tourism and Trade
GPO Box 4550
Darwin NT 0801.
For direct debit, use the authorisation reference number as the transaction reference and send to:
Account name: Department of Industry, Tourism and Trade
Financial institution: National Australia Bank
Branch number (BSB): 085 461
Account number: 932610008
Other types of payment can be made in person from 8am to 4pm, Monday to Friday at:
Mineral Titles front counter

Darwin NT 0800.
A bank guarantee must be provided by an Australian bank. It should be made out to the Minister for Mining and Industry, have no expiry date and refer to the mining authorisation number as advised by the department.
Do not include titles or project names on the guarantee.
You will also need to provide proof the guarantee has been signed by an authorised officer of the financial institution and that they have authority to issue the type, form and amount of security.
You can post or present in person your bank guarantee using the details above.
All payments must quote the authorisation reference number provided by the department to make sure the payment is recorded against your authorisation.
Interest on security deposits
Security deposits are held in trust by the department. No interest is paid.
Mining operators must pay an annual levy to fund work to address the environmental impacts left by mines that were not adequately rehabilitated in the past.
The non-refundable levy is equivalent to 1% of the total amount of the security held on 1 July each year for each site authorised under the Mining Management Act 2001.
How the levy works
The levy is calculated on the amount of the security held for each mine site at 1 July each year. The amount of the levy will not change during the year even if the security increases.
For large levy amounts, operators can pay quarterly instalments or make other arrangements with the department.
What the money is used for
The levy funds go into the Mining Remediation Fund to rectify or minimise the environmental impacts of mining sites that were inadequately rehabilitated before mining securities were introduced in 2005, or were otherwise unfunded.
The levy also funds the department's Legacy Mines Unit to undertake remediation work.
For more information on legacy mines and the security and levy, go to the Department of Industry, Tourism and Trade website.
