[color=red][/color]Bunyans Cove Pd – Zr – Nb – Y Mineral Showing
The mineral claims at Bunyans Cove has two historic mineral occurrences recorded in the Newfoundland and Labrador Mineral Occurrence Data Base System ( Mods), one is for a lead and rare earth metals showing and other is for a pyrite showing. The PB - REE showing is described in more detail below.
Bunyans Cove Pb Showing as described in the National Mineral Inventory Files.

Description of Deposit:
Minor pyrite and galena occurrence in a mafic dyke which cuts felsic volcanic close to a contact/fault with mafic volcanics (Hutchings,1998).
The host rock for the mafic dyke is a purplish-pink, massive, Mn-oxide and hematite bearing felsic volcanic, which is feldspar porphyritic (<4 mm) locally as well as some places where flow banding occurs. Flow patterns occur near mafic dyke in quartz (Rmz-040) and pyrite occurs in the felsic near the contact with the dyke.
Sample Rmz-040 is a sample from the green mafic dyke with quartz, and contains a silvery metallic mineral (Molybdenite?) up to 4 mm diameter in places.
small (trace) amounts of pyrite present.
Sample Rmz-041 is from a red to purple felsic zone with pyrite in quartz veins and locally in the massive felsic. The host is porphyritic with 170-275 cps and ~200 cps near veins. Veins are weathered rusty and have disseminated and massive pyrite crystals up to 4 mm in diameter. The vein is up to 8 cm wide and trends 110/60 North to 140/80 Northeast.
Samples Rmz-042 and 042b are red-purple felsic rocks around cliff from sample Rmz-040, and seem similar but are in a shear zone of sorts with readings from 300-400 cps in an apparent nondescript rock, with rusty cruddy surfaces, possibly hematite and Mn-oxide but slightly different in appearance (Hutchings, 1998).
