'''Costeaning''' is the process by which miners seek to discover metallic [[lode]]s. It consists in sinking small pits through the superficial deposits to the solid rock, and then driving from one pit to another across the direction of the [[vein (geology)|vein]], in such manner as to cross all the veins between the two pits.<br />
<br />
In the [[Northern Territory]] of [[Australia]], costeans are required to be excavated in a way which reduces disturbance to the environment.<ref>https://nt.gov.au/__data/assets/pdf_file/0013/203332/aa7-006-construction-and-rehabilitation-of-costeans-and-bulk-sample-pits-advisory-note.pdf {{Bare URL PDF|date=August 2024}}</ref><br />
