Part 5Mineral extraction allowances

Chapter 1Introduction

394Mineral extraction allowances

(1)Allowances are available under this Part if a person carries on a mineral extraction trade and incurs qualifying expenditure.

(2)In this Part “mineral extraction trade” means a trade which consists of, or includes, the working of a source of mineral deposits.

(3)In this Part “mineral deposits” includes any natural deposits capable of being lifted or extracted from the earth, and for this purpose geothermal energy is to be treated as a natural deposit.

(4)Any reference in this Part to mineral deposits is to mineral deposits of a wasting nature.

(5)In this Part “source of mineral deposits” includes a mine, an oil well and a source of geothermal energy.

395Qualifying expenditure

(1)In this Part “qualifying expenditure” means—

(a)expenditure on mineral exploration and access which is qualifying expenditure under Chapter 2,

(b)expenditure on acquiring a mineral asset which is qualifying expenditure under Chapter 3,

(c)expenditure which is treated as qualifying expenditure on mineral exploration and access under section 407(5) or 408(2), and

(d)expenditure which is qualifying expenditure under Chapter 5 (expenditure on works likely to become valueless and post-trading restoration expenditure).

But this is subject to subsections (2) and (3).

(2)Expenditure is not qualifying expenditure if it is excluded from being qualifying expenditure by section 399.

(3)Chapter 4 contains provisions limiting in certain cases the amount of expenditure which is qualifying expenditure.

396Meaning of “mineral exploration and access”

(1)In this Part “mineral exploration and access” means—

(a)searching for or discovering and testing the mineral deposits of a source, or

(b)winning access to such deposits.

(2)Expenditure on seeking planning permission necessary to enable—

(a)mineral exploration and access to be undertaken at any place, or

(b)any mineral deposits to be worked,

is treated as expenditure on mineral exploration and access if planning permission is not granted.

(3)“Seeking planning permission” includes pursuing an appeal against a refusal to grant planning permission.

397Meaning of “mineral asset”

In this Part “mineral asset” means—

(a)any mineral deposits or land comprising mineral deposits, or

(b)any interest in or right over such deposits or land.

398Relationship between main types of qualifying expenditure

Subject to Chapter 4, expenditure on—

(a)the acquisition of, or of rights over, the site of a source of mineral deposits, or

(b)the acquisition of, or of rights over, mineral deposits,

is to be treated as expenditure on acquiring a mineral asset and not as expenditure on mineral exploration and access.

399Expenditure excluded from being qualifying expenditure

(1)Expenditure on the provision of plant or machinery is not qualifying expenditure except as provided by section 402 (pre-trading expenditure on plant or machinery).

(2)Expenditure on works constructed wholly or mainly for subjecting the raw product of a source to any process is not qualifying expenditure, unless the process is designed for preparing the raw product for use as such.

(4)Expenditure on a building is not qualifying expenditure if the whole of the building was constructed for use as an office.

(5)Subsection (6) applies if part of a building or structure has been constructed for use as an office.

(6)The expenditure on the office part is not qualifying expenditure if it was more than 10% of the capital expenditure incurred on the construction of the whole.

Chapter 2Qualifying expenditure on mineral exploration and access

400Qualifying expenditure on mineral exploration and access

(1)Expenditure on mineral exploration and access is qualifying expenditure if—

(a)it is capital expenditure, and

(b)it is incurred for the purposes of a mineral extraction trade.

(2)Expenditure on mineral exploration and access incurred by a person in connection with a mineral extraction trade which that person carries on then or subsequently is to be treated as incurred for the purposes of that trade.

(3)But pre-trading expenditure on mineral exploration and access is qualifying expenditure only to the extent provided by—

• section 401 (pre-trading exploration expenditure), or

• section 402 (pre-trading expenditure on plant or machinery).

(4)Any pre-trading expenditure that is qualifying expenditure under either of those sections is to be treated as incurred on the first day of trading.

(5)In this Chapter—

(a)“pre-trading expenditure” means capital expenditure incurred before the day on which a person begins to carry on a mineral extraction trade, and

(b)“the first day of trading”, in relation to a person’s pre-trading expenditure, means the day on which that person begins to carry on the mineral extraction trade.

401Pre-trading exploration expenditure

(1)This section applies if—

(a)a person incurs pre-trading expenditure on mineral exploration and access at a source, and

(b)the expenditure is not incurred on the provision of plant or machinery.

(2)The amount of the expenditure (“pre-trading exploration expenditure”) that is qualifying expenditure depends on whether mineral exploration and access is continuing at the source on the first day of trading.

(3)If it is, so much of the pre-trading exploration expenditure as exceeds any relevant receipts is qualifying expenditure.

(4)If it is not, only so much of the pre-trading exploration expenditure as—

(a)was incurred within 6 years ending on the first day of trading, and

(b)exceeds any relevant receipts,

is qualifying expenditure.

(5)“Relevant receipts” means capital sums received—

(a)by the person incurring the pre-trading exploration expenditure referred to in subsection (3) or (4), and

(b)before the first day of trading,

so far as they are reasonably attributable to that expenditure.

(1)This section applies if—

(a)a person incurs pre-trading expenditure on the provision of plant or machinery for mineral exploration and access,

(b)the plant or machinery was used in connection with mineral exploration and access at a source, and

(c)before the first day of trading, the plant or machinery is sold, demolished, destroyed or abandoned.

(2)The amount of the expenditure (“pre-trading expenditure on plant or machinery”) that is qualifying expenditure depends on whether mineral exploration and access is continuing at the source on the first day of trading.

(3)If it is, so much of the pre-trading expenditure on plant or machinery as exceeds any relevant receipts is qualifying expenditure.

(4)If it is not, only so much of the pre-trading expenditure on plant or machinery as—

(a)was incurred within 6 years ending on the first day of trading, and

(b)exceeds any relevant receipts,

(3)In this Chapter “the buyer”, in relation to the acquisition of a mineral asset, means the person acquiring it.

404Exclusion of undeveloped market value of land

(1)If the mineral asset is an interest in land, so much of the buyer’s expenditure on acquiring the asset as is equal to the undeveloped market value of the interest is not qualifying expenditure.
