MDN Terminates Prairie Lake Option

MONTREAL, QUEBEC--(Marketwired - Feb 19, 2016) - MDN Inc. (TSX:MDN) (the "Company") announces that it decided to not continue the exploration campaign on the Prairie Lake properties and has therefore terminate the option agreements with the claims owners.

Despite the high-grade niobium grab samples collected during the 2015 summer exploration works, the project was considered too grass-root and needed significant investments in order to determine the presence of a carbonatite deposit. MDN Inc. prefers to preserve its liquidities and to focus on more advance projects. The decision is said to be strategic in the current difficult context for junior mining companies.
