A mining company is again showing interest in drilling near Corner Brook's water supply.

Thomas Resources has re-submitted an application to drill 21 holes in the area.

The mining company had filed a similar application earlier this year, but the city changed its development regulations.

Corner Brook council has since signed a new integrated municipal sustainability plan, or IMSP, which changed the way such applications are dealt with.

"Even though this is a new application, all the comments and what-not that we received in the previous process will be reviewed by council," Corner Brook Mayor Neville Greeley said.

Under the new plan, mineral exploration is considered a discretionary use within a watershed area.

Residents have two weeks to submit their concerns about drilling near Corner Brook Lake.

Some of them are already making their opposition known.

"What comes out of our tap is far more important than what they are bringing out of the ground there at that location," Glen Keeling said.

Llew Hounsell says he doesn't mind mining exploration "but not inside a watershed — not where 20,000 people get their drinking water."

Council will vote on the new application at the next public meeting in August.
