Location: 

  • 50 kilometres east of Kasabonika, Ontario and 68 kilometres north-west of Webequie, Ontario. Access by float plane or helicopter

Targeted Commodities:

  • VMS (Volcanic Massive Sulphides), Nickel, PGE Platnium group elements

Land Position:

  • 21 contiguous mining claims, covering an area of 48.1 square kilometres.

Stage of Exploration:

  • Airborne Geophysics was completed in 2008
  • Prospecting
  • Ground Geophysics, Down Hole EM Pusle Geophysics
  • 2011 Drill program completed with 2553.9 metres drilled

2011 Drill Program:

The most notable units discovered have proven to be numerous vanadium-rich magnetite gabbro layers (near massive magnetite locally) with robust apparent thicknesses ranging from 20-40 meters .

Additionally, gabbroic units containing strong sulphide zones with semi-massive to massive sulphides of 1 to 2 metres in thickness have been encountered, with the margins of these zones consisting of sulphide ‘stringers’ containing visible pyrrhotite, chalcopyrite and lesser pentlandite.  Olivine-bearing, magnetic gabbro was also encountered in the final drill hole of the program; SH11-09.  Drilling to follow up on this ultramafic material will continue in the fall of 2011 with the goal of defining nickel bearing ultramafic units stratigraphically lower in the intrusive suit. Highlights are the program are listed below:

  • Multiple semi-massive to massive sulphides of 1 to 2 metres in thickness have been encountered
  • Additional geophysical targets identified using surface magnetics and Crone pulse EM
  • Numerous vanadium rich gabbro layers with significant thickness were encountered
  • Olivine-bearing, magnetic gabbros were intersected
  • Zones of platinum, palladium and gold (Pt, Pd and Au) enrichment were identified within the mafic intrusive body
  • Diamond drill hole SH11-08 assayed 0.703 g/T Pd, 0.276 g/T Pt and 0.344 g/T Au from 215.65-216m
  • Elevated nickel and cobalt (most notably SH11-04 which assayed up to 1610 parts per million (ppm) Ni and 1040ppm Co, and SH11-05 which assayed up to 1160ppm Ni) was found associated with disseminations of pyrrhotite and inter-grown pentlandite
  • An off-hole conductor beneath SH11-04 and SH11-05 has been interpreted.  The assay results warrant another hole deeper and to the west to intercept the interpreted conductor
  • Elevated copper assays (most notably SH11-02 and SH11-06 which assayed up to 1.04% Cu and 0.88% Cu respectively)

Mineralization Potential:

  • Ultramafic intrusive environment ocisting of alternatind sperpentinized unltramafic-grabbroic rocks within each zone with the frequency of gabbroic rocks increasing to the north.
  • The geophysical data exhibits the characteristics of an intact intrusive body
  • Modeling of the magnetic data outlined a magnetic feature, which is dimensionally about >10km long by 3-4km wide and extending to at least 3km below surface.
  • The modeling also exhibits features similar in nature to four of the Voisey’s Bay intrusive components; the Eastern Deeps, Discover Hill Zone, the Ovoid, and the Reid Brook Zone (feeder sheet).
  • Described as a Voisey-s Bay look-alike by leading experts in the nickel field.

Geological Interpretation by Larry Hulbert D.Sc.:

In detail, the magnetic fabric of the intrusive body is remarkably similar in size, shape and form to that of the Voisey’s Bay Complex in Labrador which hosts world-class Ni-Cu deposits, and was the last significant Ni-Cu discovery in North America (1994). 

Magnetically, the mafic-ultramafic rocks underlying the Semple-Hulbert property stand out regionally as a striking magnetic anomaly. Based on the Geological Survey of Canada regional airborne magnetic surveys the intrusive rocks on this property are approximately twice as magnetic as any other known mafic-ultramafic body in the "Ring of Fire" (ROF) including the southeast portion of the ROF which hosts the recently discovered world-class Ni-Cu-PGE, Cr and Fe-Ti-V deposits.  Detailed magnetic surveys conducted as part of a VTEM airborne geophysical survey over the Semple-Hulbert property enhanced the significance and understanding of this regional anomaly even further.

The detailed VTEM magnetic survey outlined a "spoon-shaped" intrusion. The East-West trending linear magnetic feature is analogous to the handle of the spoon and geologically is believed to represent a feeder-dyke. At its eastern end it flares out to a width of approximately 3 km and resembles the bowl portion of a spoon. This bowl shaped area represents the main mass of the magmatic chamber. The distinctive magnetic fabric within the main mass of the intrusion clearly defines an internal stratigraphy indicative of magmatic layering as is the case at Voisey’s Bay. When one examines the location of the electromagnetic conductors from the VTEM survey relative to the magnetically defined geology the Voisey’s Bay analogue and exploration model is most compelling.
