Lyndhurst Mine - Partial JV on Mining Concession - Polymetallic JV
Destor & Poularies Townships, Quebec (NTS 32D10 - 11)

Property Description and Location

The Lyndhurst property consists of 90 claims and one mining concession (CM443) which totals 3,507 ha straddling the township line of Poularies to the north and Destor to the south.  The property is located 35 km north of Rouyn-Noranda, Quebec immediately east of Highway 101 which connects Rouyn-Noranda with La Sarre.  The area is characterized by low relief with slow running streams and small lakes and ponds. 

These claims are wholly owned by Globex and are not subject to any underlying royalties or third party interests except for the Lyndhurst mining concession which is subject to a royalty to the vendors. A portion of the mining concession is jointed ventured with local entrepreneur Agrégat-R-N inc.

 

Lyndhurst Property

 

History

The Lyndhurst property has been explored intermittently by various exploration companies since the late 1920’s.  In 1955, Lyndhurst Mining Co. Ltd. sank a 215 m shaft, carried out some development on five levels and proceeded with limited mineral production after completing an underground exploration diamond drill program which indicated a historic resource of 347,000 t grading 1.95% Cu from two sulphide lenses.  It is reported that 148,000 t of material grading 1.93% Cu was extracted between 1956 and 1957.  These historical resource and production figures should not be relied upon as they have not been prepared by a Qualified Person under NI 43-101 or to Canadian Institute of Mining and Metallurgy (CIM) Definition Standards for Mineral Resources & Mineral Reserves. 

Following this limited mining activity, surface exploration including trenching and mostly shallow drilling, was carried out by various companies until 1988.  Minnova Inc. completed an airborne EM (INPUT) survey and follow-up with DEEP-EM ground electromagnetic surveys, geological and lithogeochemical sampling, stripping and some diamond drilling in 1988.  From 1991 to 1993, Noranda Exploration carried out geological mapping, outcrop stripping, induced polarization and horizontal-loop electromagnetic surveys and diamond drilling, without encountering any significant new VMS mineralization.  The property remained dormant until 1997.

Exploration and Development

From 1997 to 2000 the property was optioned by Vancouver junior Amblin Resources Inc. who, under the operatorship of Globex, completed an airborne magnetic/electromagnetic survey and a subsequent ground gravity survey.  A gravity anomaly west of the Lyndhurst deposit was drilled at a shallow depth in 1998 and complimentary borehole geophysics identified further anomalies warranting more drilling.  Six additional drill holes (LY-98-01 to 98-05 and 98-05a) lead to the discovery of the deep seated (1,150 m from surface) volcanogenic massive sulphide Moses Zone identified from the initial holes as mostly narrow Cu/Zn/Ag mineralization including 3.6% Cu, 58.3 gpt Ag/1.2 m, 3.7% Zn/1.9 m and 5.7% Zn/3.6 m (discovery hole LY-98-05); 3.6% Cu, 2.9% Zn, 159.3 gpt Ag/2.6 m (hole LY-98-05A, a 110 m undercut to hole LY-98-05).  Two subsequent deeper holes (LY-98-06 and 06a) encountered wider massive sulphide intercepts grading 3.9% Cu, 34.9 gpt Ag/6.4 m (LY-98-06a) and 2.6% Zn, 13.7 gpt Ag/8.4 m (LY-98-06a).  Hole LY-98-06, a 90 m undercut to hole LY-98-05A suggests improvement in thickness of the sulphide lenses with depth. 

In 2000, Globex completed additional drilling in the Moses Zone area which returned two narrow zinc mineralization zones in massive sulphides, including 6.8% Zn, 33.0 gpt Ag/0.5 m and 5.2% Zn, 35.6 gpt Ag/2.9 m (hole L00-8B).  Shallow drilling in 2001 and 2004 by Globex in the No.1 Zone (250.m east of the original Lyndhurst deposit), intersected mostly narrow Cu/Zn/Ag/Au values with the better widths in the No.1 Zone including 1.36% Cu, 26.5 gpt Ag/7.38 m in hole L-04-02 at a vertical depth of 35 m in a brecciated high silica sulphide stringer zone hosted in rhyolite within a larger envelope of mineralization grading 0.83% Cu, 16.42 gpt Ag/17.2 m.  Continued drilling of the shallow No. 1 Zone copper mineralization in 2007 (21 holes totaling 2,000 m) did not prove sufficiently encouraging to pursue the concept of potential open pit extraction.  Between 2008 and 2010, new deep penetrating geophysical orientation tests were undertaken including; IP, magneto-tellurics and an airborne gravity survey in the vicinity of the Lyndhurst deposit, the #1 Copper-Silica Zone and Moses Zone. These surveys focused an 8 hole, relatively shallow drill program of 2,942 m which did not encounter any significant new VMS mineralization.

In 2011, a 56.5 km dipole-dipole IP survey at 100 m line separation was completed over the western half of the property, covering approximately 4.5 km of ground westward along strike from the known Lyndhurst/Moses Zone VMS occurrences.  This survey work was successful in tracing several known mineralized trends including the historic Beattie zinc stringer zone, where selective historic grab samples assayed best values of 31.6% Zn, 3.0% Pb, 200 gpt Ag; 8.8% Zn, 33 gpt Ag; and 6.6% Zn, 31 gpt Ag.  The wide array IP suggested geophysical continuation to depth (>200 m) of the disseminated and stringer sulphides found at surface at both the main Beattie Zinc showing and Beattie North zinc stinger zone, identifying a priority drill target. 

In 2012,  a single deep, 997 m drill hole (LYN-12-01) was completed to test for the presence of volcanogenic massive sulphides down dip from the surface rhyolite-hosted disseminated and stringer sphalerite zones of the Beattie Zinc Showing and Beattie North zinc stringer zone at vertical depths of 325 m and 650 m respectively.  No significant zones of copper-/zinc-bearing massive sulphides were encountered although intermittent and wide (75-100 m core length) haloes of weak chalcopyrite or sphalerite, pyrite-quartz stringers and locally intense black chlorite alteration were intersected at both anticipated down dip projections of these surface occurrences.  A borehole geophysical survey in Lyn-12-01, while responding to the multiple narrow Cpy stringers, failed to detect any off-hole conductor suggestive of the presence of a larger conductive massive sulphide lens within an estimated 100 m radius of the drill hole. 

In 2013 a review of all available exploration data along with targeted surface mapping were undertaken and it was concluded that the property scale exploration potential for blind, potentially large VMS deposits within the extensive hydrothermally altered Lyndhurst felsic volcanic complex  lies below a minimum vertical depth of 800 m.  An experimental ambient frequency surface geophysical survey was conducted over the deep seated Moses sulphide zone however this test failed to definitively demonstrate its ability to detect the presence of deeply buried conductive sulphides. 

In the light of these findings, it is concluded that any meaningful further deep exploration work would require a focus on stratigraphic drilling.  Several deep targets have yet to be fully assessed. 

In 2014, work to re-evaluate deep stratigraphic drilling at the Moses VMS zone and the under-explored eastern sector of the property continued.  Rehabilitation work in connection with the exploration program on the Lyndhurst property continued at the old Lyndhurst mine site and will be completed in 2015 with re-vegetation of closed areas.  Surface water tests will then be taken twice a year to monitor local water quality at the site. New exploration work will be considered based on 2015 budget priorities.
