Welcome To The Inspiration Mining HUB On AGORACOM
The company is exploring for nickel deposits on its Langmuir property near Timmins, Ontario; for nickel-gold-copper on its Cleaver and Douglas properties; and for molybdenum and rare earth elements at recently acquired Desrosiers property.

1.13 MINERAL RESOURCE AND MINERAL RESERVE ESTIMATES
Langmuir North Deposit: A digital database was provided to Micon by Inspiration wherein such drill hole information as collar location, down hole survey, lithology, density measurements and assays was stored in comma delimited format. The drill hole information was provided on an on-going basis as new information became available after the date of Micon’s site visit. The cut off date for the drill hole database was October 28
The mineral resources are estimated at 8,324,000 tonnes grading 0.40% Ni. Micon believest hat sufficient information is available to classify the mineral resources in the Indicated Resources category.
Langmuir No. 1 Deposit:
A digital database was provided to Micon by Inspiration wherein such drill hole informationa s collar location, down hole survey, lithology, density measurements and assays was stored in comma delimited format. The drill hole information was provided on an on-going basis as new information became available after the date of Micon’s site visit. The cut off date for the drill hole database was October 28th, 2009 and included all drill hole information up toand including hole L108-123.
The mineral resources are estimated at 1,733,000 tonnes grading 0.51% Ni. Micon believest hat sufficient information is available to classify the mineral resources in the Indicated Resources category.
1.14 INTERPRETATIONS AND CONCLUSIONS Inspiration Mining Corporation has been conducting exploration programs on its Langmuir Project located south of Timmins, Ontario with the goal of discovering additional occurrences of nickel mineralization similar to that which had been exploited in the past at the Langmuir #1 and Langmuir #2 mines. These exploration programs have been successful in outlining sufficient concentrations of nickel at the Langmuir North deposit and at the Langmuir No. 1 deposit to prepare an initial mineral resource estimate. As well, according the information presented in Jensen (2009), exploration drilling elsewhere on the property has been successful in discovering the presence of nickel mineralization of potentially economic grades across potentially mineable widths in such locations as between the Langmuir #1 and Langmuir #2 mines and in the extreme northwestern portion of the property. The historical production record of the Langmuir property clearly demonstrates that (potentially) economic quantities of nickel mineralization have indeed been demonstrated to be present on the property. While the property has been the subject of previous exploration programs whose goals, presumably, were the location of additional deposits with similar grades as were exploited at Langmuir No. 1 and Langmuir No. 2 mines, Micon believes that given the economic context of the time, little attention has historically been directed towards evaluating the potential of the presence of near-surface, lower grade mineralization that could be exploited by means of open pit mining methods.
On the basis of the exploration work completed to-date, Micon agrees with Inspiration’s opinion that potential remains to locate additional nickel mineralization similar to that which has been outlined at the Langmuir North and Langmuir No. 1 deposits. Micon believes that the potential exists on the property to locate an additional 20-40 million tonnes of nickelbearing material at similar grades to those found at the Langmuir North and Langmuir No. 1 deposits. As well, Micon agrees that potential remains to locate additional concentrations of nickel mineralization similar to that which has been exploited at the Langmuir No. 2 mine at depth. It is to be stressed that the potential quantity and grade is conceptual in nature, that there has been insufficient exploration to define a mineral resource of said tonnage and grade, and that it is uncertain if further exploration will result in the target being delineated as a mineral resource.
Micon believes that Inspiration is justified in carrying out further exploration programs whose goals are to locate additional nickel-bearing zones on the Langmuir Property.
In respect of the exploration potential of the property, Micon suggests the following:
Continue exploration drilling to search for possible concentrations of higher grade nickel mineralization beneath the known deposits (Langmuir #1, Langmuir #2 and Langmuir North. Micon envisions that such drilling be carried out initially at a wide spacing. Down-hole geophysical surveys (bore hole pulse EM) surveys would be carried out in these deeper drill holes to search for the possible presence of conductive sulphide mineralization in the vicinity of these bore holes.
Deep-searching, surface-based EM surveys be carried out along those magnetic anomalies that are observed or interpreted to be related to ultramafic host rocks. Such surveys would be designed to search for higher grade sulphide mineralization at depth. Anomalies identified should be tested by surface-based diamond drill holes.
Prepare a detailed compilation of the surface and three-dimensional geology and mineralized zones from all available sources to assist in identification of exploration targets in the favourable peridotite units. Such a compilation ideally would be completed using all available drill hole data.
Examine the environs of the Langmuir #2 deposit by means of shallow drill holes for the possibility of low-grade, near surface mineralization that may be exploited by open pit mining methods.
