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.
Well let's re-read what Micon had to say to ISM after they wrote their report. I wonder how many of these suggestions they have pursued and which has the "best bang for it's buck" N77 make note of the last 2 on the list. Also can I presume that some suggestions indicate there may have been deficiencies prior?
**********************************************************************
In respect of the exploration potential of the property, Micon suggests the following:
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.
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.
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.
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.
In respect of the project development aspects of the project, Micon suggests that:
Given the suggested relationship of the bulk density to the nickel grades at the Langmuir No. 1 deposit, Micon recommends that future mineral resource estimates be prepared using the detailed bulk density information so that accurate local estimates of the mineralized tonnages can be derived.
The metallurgical test work on the Langmuir North be completed and metallurgical testing be initiated for the Langmuir #1 deposit
All future met test work should be carried out on a sulphide nickel (Ni(AR)) basis so as to maintain consistency across the project.
The inter-element relationships show that a positive relationship is present between nickel, palladium and platinum where higher palladium and platinum values are correlated with higher nickel values, suggesting the presence of a Ni-Pd-Pt-bearing mineral such as braggite (Pt, Pd, Ni)S in the mineralization found at the Langmuir North deposit. Micon therefore recommends that the palladium and platinum grades in concentrate be determined in any future metallurgical testing programs.
Modify the geological drill hole database to explicitly state the assay method used for the nickel assays for clarity.
Preliminary geotechnical investigations be completed to suggest maximum rock and soil slope angles in support of future open pit modeling exercises.
Preparation of a preliminary assessment be completed to study the economic viability of the mineralization discovered to-date."
Recall that the 43-101 was finally only released last January 2010,,,,,,,So many unknowns at that early stage that Micon keeps referring to.
"Given the early stage of the project’s development, no detailed information is available in respect of operating costs for mining, processing and general and administration in respect of a potential open pit mining operation. As well, no geotechnical information is available upon which to estimate an overall slope angle. Consequently, Micon derived estimates for these items on the basis of its experience in the region and from general knowledge. It is to be noted that the estimates presented are only for the purpose of developing an initial optimized open pit shell, and the assumed values will likely change with further detailed work."
