Buchans Wileys Property Buchans Wileys Property Summary Buchans Wileys Property - Download | Proximity Map

The Buchans Wileys Property consists of three mineral licence (20533M – 28 claims, 20535M – 8 claims,  20466M – 6 claims) consisting of 44 contiguous, map-staked claims, covering a total area of 11 square km. The property is located on NTS map sheet 12A/15, approximately three kilometers south of the town of Buchans in central Newfoundland. The Wileys property is located 3-4 km southwest of the past producing Buchans Mine. The Buchans Mine produced 16,196,876 tonnes of ore at an average mill head grade of 14.51% zinc, 7.65% lead, 1.33% copper, 126 grams/tonne silver and 1.37 grams per tonne gold. This places it among the highest grade ores in North America. Four km to the west of the property, the Clementine Prospect, reported grades of 15% combined Zn/ Pb/Cu over 3.96 meters and 17.4 combined Zn/Pb/Cu over 2.1 meters
The Buchans area including the Wileys property is underlain by the Middle Ordovician Buchans Group. The group is a subaqueous sequence of mafic volcanic rock and coarse immature clastic sediments forming the south end of a sinuous volcanic belt approaching 200 km in length. The Buchans Group from bottom to top is comprised of the Lundberg Hill, Ski Hill, Buchans River and Sandy Lake formations. The Buchans River Formation is the only known formation within the Buchans Group to host significant in‐situ VMS mineralization. Within the Wileys property the Buchans River Formation is referred to as the Wileys Trend. The Wileys Trend/ Buchans River Formation within the property is inferred from overlying and underlying formations to be a moderately north dipping band several hundred meters wide and extending the entire length of the property in east northeast direction.

The Buchans VMS ores consist predominantly of base‐metal sulphides and barite and have many similarities to the Kuroko‐type deposits of Japan. Both high‐grade 'in‐situ' and 'transported' ores have been exploited. The former are zoned massive sulphide deposits underlain by lower grade, pyritic stockwork zones. The latter are coarse, heterogeneous deposits of sulphide and lithic fragments, and are interpreted as debris flows derived in part from the in‐situ ores and redeposited in paleochannels. The in situ ores are hosted in felsic volcanic rocks of the Buchans River Formation, underlain by locally intense stockwork alteration developed in the Buchans River and underlying Ski Hill Formation. Intense quartz‐chlorite‐pyrite with base metals and barite is the most proximal alteration style, and gives way to peripheral assemblages of chloritecarbonate‐ pyrite and sericite‐pyrite‐silica‐clay alteration. The outermost alteration fades out gradually and may extend up to 1 km from the massive sulphides. The sphalerite‐barite dominated orebodies at Buchans are generally poorly conductive, making them a difficult exploration target. However, the alteration zones present at Buchans, with associated pyrite and base metals, serve to both enlarge the target areas, and to provide a means of detecting them with relatively rapid and inexpensive.

Historically the ground covered by the Wileys property has been the subject of a moderate amount of prospecting, geochemical, geophysical and drilling programs. Results from the exploration programs include high grade massive sulphide and barite float discovered in Wileys Brook. Geochemically several basal till anomalies were outlined. Geophysical programs outlined several chargeability, gravity and IP anomalies. A small number of the geophysical anomalies were drill tested. While the drilling program failed to intersect any significant alteration or mineralization and may not have even cut the Buchans River Formation in any hole, the drilling has provided some deeper cuts into rocks most likely near the base of the Sandy Lake Formation which directly overlies the ore horizon Buchans River Formation, in an area with relatively little historic drilling. Considering the complicated stratigraphy and structure of the Buchans Camp with all ore‐bearing sequences contained within thrust fault bounded panels it can’t be overlooked that the Buchans River Formation could lie very close, beneath current drilling, without any evidence of alteration and mineralization in overlying panels, but beyond the detection limit of surface geophysical systems.

With deeper drilling in mind, down hole geophysics should be carried out on all previous drill holes
