Wolverine Identifies A Large, Strongly Anomalous Gold In Soil Zone At Its Vivi Property
WOLVERINE MINERALS CORP. -- ("Wolverine" or the "Company") is pleased to announce positive results from a recently completed exploration program at its Vivi property, which is located in the Finlayson District of southeast Yukon. The Company identified a large zone (400 m by 900 m) of strongly anomalous gold-in-soil geochemistry, which it plans to drill test next summer.
Exploration activities on the 1400 hectare Vivi property consisted of grid and contour controlled geochemistry (1247 soil samples), prospecting (65 rock samples) and geologic mapping, between mid-June and mid-September.
The Vivi property is underlain by a series of shallowly dipping thrust panels of Upper Devonian Kudz Ze Kayah Formation meta-sedimentary and meta-volcanic rocks and Mississippian or later ultramafic rocks and related talc-carbonate altered zones (Figure 1).
Approximately 45% of the property was soil sampled in 2011. Sampling returned a coherent gold anomaly ("JPR Anomaly") in a 400 m by 900 m area, hosting numerous strongly anomalous gold values (200 to 1320 ppb) plus smaller clusters and single point anomalies that contain values ranging from 261 to 1370 ppb gold. The JPR Anomaly coincides with a thrust fault-bounded wedge of talc-carbonate altered ultramafics. Most of the secondary anomalies are attributed to glacial or downhill dispersion from the JPR Anomaly. Arsenic-in-soil response within the JPR Anomaly is moderate (background to 158 ppm) while samples collected downhill from it returned values up to 224 ppm arsenic. A second arsenic anomaly with values ranging up to 382 ppm lies east of the JPR Anomaly in an area with weak to moderate gold response. This anomaly is situated downhill from a second thrust fault-bounded talc-carbonate altered wedge. The Company is currently conducting heavy mineral analysis on selected soil sample pulps to try and determine the nature of the gold.
Limited prospecting has so far failed to explain the soil geochemical anomalies and has returned only background to weak gold values (up to 0.225 g/t). The source of the gold-in-soil may be recessively weathering zones that lie within the talc-carbonate altered rocks or along their bounding faults.
Jim Dawson, Vice President of Exploration for Wolverine Minerals comments "Due to the well constrained geologic model and intensity of the gold-in-soil geochemical values, the Company is pleased to announce that it plans to drill test the JPR Anomaly in 2012."
Analytical work was done by ALS Chemex with sample preparation in Whitehorse, Yukon and assays and geochemical analyses in North Vancouver, British Columbia. All rock samples were initially analyzed for gold by fire assay followed by atomic absorption (Au-AA24) and 35 other elements by aqua regia digestion and mass spectrometry (ME-MS41). Overlimit values for lead were determined using Pb-OG46. Soil samples were dried, screened to -180 microns, and then analyzed for 35 elements using an aqua regia digestion followed by inductively coupled plasma and atomic emission spectrometry (ME-ICP41). An additional 30 g charge was further analyzed for gold by fire assay fusion with inductively coupled plasma and atomic emission spectrometry (Au-ICP21).
The 2011 fieldwork was conducted by Archer, Cathro & Associates (1981) Limited under the supervision of Heather Smith, P.Geo. and the guidance of James M. Dawson, P.Eng., who are both qualified persons as defined by National Instrument 43-101. The technical data in this news release has been reviewed and approved by Ms. Smith and Mr. Dawson.
