Mont Saint-Hilaire has been and continues to be an excellent provider of new mineral species to science since it was brought to the attention of mineralogists in 1963 by Frank Melanson. As many problematical species were recovered it was necessary to assign code names to the unknowns.
The present list includes the code names up to UK #113, 42 of which are still unidentified (several UK’s in description process). The following table will link to a brief description of their properties, rock environments, associated minerals and fluorescence to help in their recognition. A (p) indicates a photo is available for that UK, expect many more soon. At this time only UK-33, -52, -53, -60, -86, -107 and -113 have photos. The unknowns will also be categorized in three categories: (only UK -75, -92, -99, -105, -107 and -108 for now)
Some notes on the progress of some of the unknowns have been added to the following UKs: -75, -99, -107, and -108. Those are updates from Dr Andy McDonald of Laurentian University.
 | signifies that this unknown is on the fast-track toward description. |  | means that this UK will need some help if it wants to go forward. |  | indicates that this unknown is at a dead end for the time being. |
