Tribute mining is an arrangement by which a person, partnership or company works a mine or part of a mine, under a tribute agreement with the titleholder of that mine, and either pays to or receives from the titleholder a proportion of the production of the mine or of the value of the production. Miners working in this way are known as tribute miners or tributers, and the mine is said to be worked 'on tribute'. The arrangement differs from conventional contracting and employment, both in its nature and its origins.
A tributer is distinguished, from both an independent contractor and employee, in that the tributer takes over the running of the mine, or an agreed part of it, and is remunerated in a specific manner. The origins of tribute mining lie in the

and the actual hours of work and other costs incurred during mining. A tributer needed skills, other than purely mining skills, to assess the likely value of production in the ground to be worked, under the tribute agreement, and to strike an appropriate deal on the share of production that is appropriate to the costs and effort of the mining work.
Tributers may or may not have had to fund, in part or in full, processing of the ore, mining tools, mine timber, explosives, drills, candles and other consumables necessary for mining, or the tribute agreement may make such items the responsibility of the titleholder of the mine. Mining

. Tribute agreements were defined and regulated under mining legislation. The arrangement commonly arose when the titleholder (in Australia, almost always a lessee) of a mine ceased working the mine, but agreed to let another party work the mine, usually on a smaller scale than previously.
Usually, tribute miners would be former employees of a hitherto closed or partially-closed mine, with some existing knowledge of its ore body and its likely extent and
