Regional Geology

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.

The "Geological & Geochemical Assessment Report – Nelson Property" by C.J. Wild, P. Eng., states that a few small lenses of greenstone occur west of Gorman Creek. This unit is believed to be of the Lower Jurassic Rossland Formation. There has been limited regional correlation of structures and geology in this area as it is all mapped regionally, as porphyry granite.

Local Geology

The outcrops located in the Mount Nelson area are fairly limited (Wild, 2006). Quartz lenses, pegmatites and aplites are common throughout the property. There is a large quartz porphyry body near the centre of the grid within the granite unit. A majority of the molybdenite appears to occur along the contacts of these rocks. Quartz veining does occur on the property in all rock units and appears to be most concentrated around the porphyry. Wild determined that the quartz-feldspar pegmatite bodies were spatially related to the quartz lenses but of different texture with less k-spar and muscovite.

The main molybdenum mineralization appears to be limited to a sericitized granite unit and occur as fine blebs or "rosettes" (Wild 2006). Measurement of the mineralized zone during the field trip resulted in a strike direction of 048 degrees, dipping 80 degrees to the west. Apparent plunges of the quartz lenses were measured at 12 degrees to the north.
