Working interest is the ownership interest that would require the participation in production expenses. [3] Mineral interest is the percentage of real property interest after severance of oil and gas from surface rights. [4] Tract participation factor is the number of lease acres of the lessor divided by total number of acres. [5]
Net Revenue Interest: the share of income received, connected to a working interest; Royalty Interest: the share of income received, unrelated to a working interest, and therefore received without paying any well expenses; usually connected to a leased mineral ownership. When a mineral owner signs a lease, he receives a royalty interest.
Mineral resource estimation is used to determine and define the ore tonnage and grade of a geological deposit, from the developed block model.There are different estimation methods used for different scenarios dependent upon the ore boundaries, geological deposit geometry, grade variability and the amount of time and money available.
The oil depletion allowance in American (US) tax law is a tax break claimable by anyone with an economic interest in a mineral deposit or standing timber. [citation needed] The principle is that the asset is a capital investment that is a wasting asset, and therefore depreciation can reasonably be offset (effectively as a capital loss) against income.
Mineral deposit density models start with the areas of well-explored control tracts where the number of deposits that are consistent with the grade-and-tonnage model are used. The resulting frequency distributions serve as analogs for estimation of the number of undiscovered deposits in other tracts.

World-wide distribution of MVT deposits (red), clastic sediment-hosted (green), and unclassified (blue) lead-zinc deposits. Source: USGS. Carbonate-hosted lead-zinc ore deposits are important and highly valuable concentrations of lead and zinc sulfide ores hosted within carbonate (limestone, marl, dolomite) formations and which share a common genetic origin.
