The SPDA (Sudbury Prospectors and Developers Association) is a not for profit organization dedicated to protect the interests of explorationists and junior mining companies conducting business in the Sudbury District of Ontario, Canada.
Since 1981, the SPDA has strived to protect the right to explore and extract mineral commodities from the ground. Effective lobbying by the SPDA has helped alleviate the problems caused by such items as land access, environment issues, and government regulations.
Executive members of the SPDA sit on numerous committees that include regional, provincial and federal organizations. The Sudbury group is also one of six regional groups affiliated with the Ontario Prospectors Association.
The membership includes representatives from the prospecting community, the junior exploration/mining sector, the major exploration/mining sector, and a number of service industries.
