The ISM is composed of regular, sponsoring members and honorary members.

1. Regular members can be Associations, corporate bodies and individuals (natural persons) engaged predominantly in mine surveying;

2. Sponsoring members can be Scientific and technical institutions, societies, associations, companies and other corporations promoting the objects of the ISM in an abstract or material way.

3. Honorary members can be the persons who have supported the ISM with merit in its activities.

The Presidium decides upon admission to the ISM. An appeal against the Presidiums decision can be made to the Members Assembly.

Membership of ISM ceases:

          by written notice of resignation;

          on the dissolution of an association or corporate body;

          on the death of an individual;

         by expulsion that can be determined by the Presidium in the case of gross infringement of the Statutes of the ISM or breach of obligations to the ISM; the expelled member can appeal to the Members Assembly. Cessation of membership does not release the expelled member from existing obligations to the ISM. The expelled member cannot make any claim against the ISM.
