The PPDA (Porcupine Prospectors and Developers Association) is a lobby group representing the interests of mineral explorationists in the Porcupine District of Northeastern Ontario. We concern ourselves with local, provincial and national issues affecting our members.

The association promotes mineral exploration in the region by hosting the Northeastern Ontario Mines and Minerals Symposium every other year.

As external advisory body, the association attempts to work with the government on topics such as: revisions to the "Mining Act", the Geoscience program of the Ontario Geological Survey and land-use planning.

Our membership includes individuals affiliated with the prospecting community, the junior exploration/mining sector, the major exploration/mining sector and numerous service industries.
