Project :: Big Buck Moly
Mt. Nelson, B.C.

The Big Buck Molybdenum Project is a relatively new discovery located near the top of a clear-cut logged area on Mt Nelson situated 13 km northwest of Nelson BC and is very prospective for a deposit of molybdenum.

Blebs or rosettes of molybdenum on Mt NelsonA large soil geochemical program was initiated in 2005 and was found to contain anomalous molybdenum. Further sampling was conducted in 2006 by prospector Bruce Doyle who collected 65 grab samples on the property. The five highest of the 65 samples returned values of .219 %, .199 %, .390 %, .275 %, and .549 % Molybdenum (Mo). The average grade of the 5 rock samples was .347 % Mo (Not MoS2).

Liberty optioned the property in late 2007 and extended the soil grid to the southwest during the summer of 2008 resulting in the identification of a stronger and more consistent anomaly to the SW of the original gridded area.

The Mount Nelson tenure package is composed mostly of porphyritic granite of the Jurassic Nelson Batholith suite in a report by (Little, 1964). Most outcrops were of quartz monzonite to granodiorite in composition. Quartz lenses, pegmatities and aplites are common throughout the property and a large quartz porphyry body has been mapped near the centre of the grid within the granite unit. A majority of the molybdenum appears to occur along the contacts of these rocks. Quartz veining does occur on the property in all rock units and appears to be concentrated around the porphyry. The main molybdenum mineralization appears to be limited to a sericitized granite unit and occur as fine blebs or “rosettes” (Wild 2006).

Field work conducted by Liberty in 2008 extended the soil grid area of exploration to the southwest resulting in discovery of much stronger and more consistent anomalous soil values of molybdenum.

The geological setting of the property does appear favourable for large tonnage – low grade copper – molybdenum, porphyry type deposit. Geological mapping resulted in the location of a quartz porphyry plug within the granite intrusive. Soil geochemistry anomalies occur around the perimeter of this plug with a general trend towards the southeast (overlying the gabbro plugs).

Bruce Doyle (optionee) sampling on the Big Buck Moly - Mt NelsonA thin section petrographic report was completed on a couple of rock samples from the Quartz Monzodiorite unit, at an unknown location. One sample was mineralized and magnetite rich while the other unmineralized sample was partly foliated with no magnetite. The findings showed that the molybdenum grains were not found within the magnetite grains but rather more closely associated with the Kspar, epidote, pyrite and muscovite grains (Leitch, 2008).

Even though, the mineralized sample contained magnetite, it was found not to be directly associated with the molybdenum, but a post deposition/remobilization process. Therefore, it appears that there may be a specific geophysical signature associated with the mineralization. No geophysical surveys have been conducted to investigate this theory further.

The Big Buck Moly project on the Mt. Nelson tenure is considered the Company’s first priority prospect for a ground magnetic survey because of the potential magnetic signature. Liberty intends to extend the soil grid further to the southwest and fly airborne geophysics over the property and possibly an EM survey which would help to distinguish the porphyry structures and shearing. An IP survey should produce the strongest response for disseminated molybdenum in preparation for a diamond drill program and the anticipation of discovering an economical resource on the property.

In addition to the mining option agreement Liberty holds with Bruce Doyle on the four primary tenures, Liberty has directly claimed almost all of the surrounding territory.

The property is easily accessible by the main logging road which runs directly into the project area, but is currently limited to three seasons of the year due to being un-serviced. One of the Kootenay’s large hydro electric power stations is located just to the south and a power grid runs through the tenures approximately one kilometer from the main project site.
