CA50490 - MEA: Allowances and charges: Balancing allowances: exploration and access
A balancing allowance is due where a person incurs qualifying expenditure on mineral extraction and access, and later gives up the search, exploration or enquiry without working any of the mineral deposits in question (CAA01/S427).
The allowance is equal to the unrelieved expenditure on mineral access and exploration (providing that the person is carrying on a trade of mineral extraction).
