Lets look at the spot in terms of history. You know the old saying "go fishing where the fish are"?

From the ISM website

"Langmuir Property: Inspiration Mining acquired the Langmuir property in November 2004, which includes the Langmuir #1 and Langmuir #2 mines with past production of 101,132 tonnes grading 1.74% nickel and 1,133,750 tonnes grading 1.45% nickel, respectively. Inferred resources totalling 1,017,400 tonnes grading 1.38% nickel remains in the Langmuir #1, #2, South and North zones of the property. Other zones such as the Emergency Tailings Pond and mineralization along strike from the Langmuir #1 deposit remain to be explored.

Based on these facts, Inspiration Mining believes that the Langmuir property has not been exhaustively explored, leaving room for the discovery of additional zones of massive, net-textured and disseminated nickeliferous sulphide mineralization."
