Mine Owners' Association
From Underfoot
In the United States, a Mine Owners' Association (MOA), also sometimes referred to as a Mine Operators' Association or a Mine Owners' Protective Association, is the combination of individual mining companies, or groups of mining companies, into an association, established for the purpose of promoting the collective interests of the group. Such associations are sometimes referred to as MOAs, however, in some cases they may be designated by the state, district, or locale, such as the Cripple Creek District Mine Owners' Association (CCDMOA).
