An Introduction to Ontario’s Critical Minerals, With Highlights from the Ontario Mineral Inventory

An Introduction to Ontario’s Critical Minerals, With Highlights from the Ontario Mineral Inventory provides information about the geological characteristics and economic importance of each of the 33 commodities on Ontario’s Critical Minerals List. This publication also provides an introduction to the wealth of information about the occurrence of these minerals in Ontario and highlights the information that can be gleaned from the Ontario Mineral Inventory (OMI) database.

Ontario’s Critical Minerals has a companion OGSEarth product, which highlights the Ontario Mineral Inventory records that list critical minerals as a primary or secondary commodity. The Ontario Mineral Inventory (previously known as the Mineral Deposit Inventory or MDI) is a geoscience database that provides an overview of mineral occurrences in the province of Ontario.

Recommendations for Exploration Special Edition Critical Minerals Compilation 2000-2022

For more than 50 years, the Ontario Geological Survey has presented recommendations for exploration in numerous publications and formats to promote, stimulate and support investment in mineral exploration across the province. Recommendations for Exploration Special Edition Critical Minerals Compilation 2000–2022 provides a compilation of 72 critical minerals–related articles that have been published over the past 22 years and that remain relevant today. The focus of this publication is on the exploration potential for many of the critical minerals that appear in Ontario's Critical Mineral Strategy (PDF), issued by the Ministry of Northern Development, Mines, Natural Resources and Forestry in March 2022.

Recommendations for Exploration, 2022–2023

The Ontario Geological Survey (OGS) Recommendations for Exploration, 2022–2023 are the product of the dedicated and knowledgeable staff located in the 8 Resident Geologist Program (RGP) offices across the province. The recommendations have been developed using existing OGS geological and exploration data, along with new information derived from the current year’s activities. One of the goals of Ontario’s Critical Minerals Strategy, which was released in March 2022, is to attract increased investment in critical minerals exploration. In support of this goal, many of this year’s recommendations focus on critical minerals exploration potential.
