The locality is reported as Gull lake, near Dryden, Rainy River District by J. A. Mandarino and R. I. Gait (1970). However Dryden is in the Kenora Distict, furthermore Gull Lake is nowhere near Dryden. On the assumption that Dryden is correct, the most significant molybenite occurrence near Dryden is this one. I have therefore assumed that this is the locality refered to. There is a small unnamed lake around which this and three other lesser molybdenite occurrences centre maybe this is locally called Gull Lake? Reiner Mielke ( 2014)
Anyway in 1954 an adit was driven and a bulk sample taken. Reserves were estimated to be 275,000 tonnes of 0.57% Mo.
Geology:
The Pidgeon deposit has many characteristics of a porphyry-molybdenum-stockwork deposit. The pegmatitic rocks are demonstrably posttectonic, and that molybdenum mineralization is related to a more widespread pegmatite intrusive event and localization of molybdenite in structurally induced, tensional environments. Molybdenum mineralization consists of coarse molybdenite flakes and grains associated with quartz veining/stockworks, aplitic dykes, and quartz-feldspar pegmatite veins at the outer margin of the Lateral Lake Stock. On the MPH claim group the mineralized zone dips approximately 45Β° to the south over a strike length of about 1,300 metres with an average true thickness of 60 metres. Along the north margin, dips are as shallow as 30Β° to the north. At the Pidgeon Deposit there are several modes of molybdenite mineralization. 1. Euhedral grains with K-feldspar and green mica in pegmatites. 2. Rare euhedral grains in quartz veins. 3. Along comminuted vein margins. 4. Grains and rosettes isolated in wallrocks adjacent to pegmatite veins and quartz vein stockworks. 5. Narrow bands and lenses parallel to wall rock foliation. 6. Along fractures discordant to wall rock foliation. An inferred resource of 8.5 million tonnes at 0.099% molybdenum was calculated (with a 0.4% molybdenum cut-off) which is close to the historical estimate of 9.0 million tonnes at 0.097% molybdenum.
