Prospecting for a hidden gem: OGS cataloguing mining data in the Sault district.

At the Ontario Geological Survey's Resident Geologist Office in Sault Ste. Marie, staff is undertaking a project to catalogue and digitize mining data that's been unavailable to the online public--until now.

District geologist Anthony Pace said a mining company will often donate data to the Ministry of Natural Development and Mines (MNDM), such as original mine or surface plans, after a mine shuts down, or an exploration project comes to a close.

It's information that could be valuable for future prospecting or exploration on the site, but it's only available in limited format.

"If we lose that data, the actual original data, it's gone," Pace said. "We don't even have a form of backup for it."

So staff at his office has started cataloguing it, with an aim of also digitizing it and putting it online, so that it's accessible for everybody.

The Sault Ste. Marie office oversees a district that extends from just east of Elliot Lake to south of White River, and west of Chapleau. Currently, much of the ex ploration and development activity is taking place mostly in the Wawa-Dubreuilville area, where companies like Red Pine Exploration, Argonaut Gold, and Richmont Mines are making news for their mining activity.

Often, that data can be the information that companies want coming into a new area of exploration, as it can contain crucial details associated with a property, Pace said.

"That's usually what we call our gem maps, because that's typically the stuff that companies will keep confidential," Pace said.

"They won't file it for assessment with the MNDM; they'll just file what they're required to file, and sometimes there could be some information that they'll have that they just didn't want to go public."

In some cases, that information can be the key that kickstarts a new exploration project, Pace said. It's valuable, because using information already discovered by their predecessors, prospectors can save time and money because they already have a baseline to work with, he added.

"We've had projects in my district start mainly because of the donated material that we've had," Pace said. "They were able to use this data based on this data that we catalogued, and if it wasn't for that, they probably wouldn't have acquired the property."

In the late 2000s, as the price of uranium rose significantly, there was a "big push" for uranium companies across Canada to look for new sources of the base metal, Pace noted. As a former producing Ontario...
