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 (443) which totals 3,507 hectares straddling the township lines 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.  The ground cover consists of a mixture of muskeg swamp with peripheral zones of tag alders and elsewhere, large patches of second/third generation trees including poplar, birch, balsam fir and black spruce.

These claims are wholly owned by Globex and are not subject to any underlying royalties or third party interest except for a portion of the Lyndhurst mining concession which is jointed ventured with local entrepreneur Agregat 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 metre 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 non NI 43-101 compliant 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 do not confirm to current NI 43-101 criteria or to CIM Standards and Definitions.  Following this limited mining activity, surface exploration including trenching and mostly shallow drilling, was carried out by various companies until 1988.  Minnova Inc. in 1988 completed an airborne EM (INPUT) survey and follow up with DEEP-EM ground electromagnetic surveys, geological and lithogeochemical sampling, stripping and some diamond drilling.  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

In 1997 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.  This ground geophysics outlined three gravity anomalies located within highly altered felsic volcanics 1,500 metres west and along strike of the original Lyndhurst copper deposit as well as 500 metres north of the Lyndhurst deposit.  The 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 lead to the discovery of the deep seated (1,150 metres 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/ 1.2m, 3.7% Zn/ 1.9m and  5.7% Zn/3.6m (discovery hole LY-98-05); 3.6% Cu, 2.9% Zn, 159.3 gpt Ag/ 2.6m (hole LY-98-05A, a 110m undercut to hole LY-98-05).  Two subsequent deeper holes encountered wider massive sulphide intercepts grading respectively 3.9% Cu, 34.9 gpt Ag/6.4m  and 2.6% Zn, 13.7 gpt Ag/ 8.4m (hole LY-98-06, a 90 metre undercut to hole LY-98-05A) suggesting 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 in massive sulphides including 6.8% Zn,33.0 gpt Ag/ 0.5m and 5.2% Zn,35.6 gpt Ag/2.9m (hole L00-8B).  Shallow drilling in 2001 and 2004 by Globex in the No.1 (250 metres 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 g/t Ag/ 7.38m at a vertical depth of 35 metres in a brecciated high silica sulphide stringer flood zone hosted in rhyolite within a larger envelope of mineralization grading 0.825% Cu, 16.42 gpt Ag/ 17.2m.  Continued drilling of the No. 1 Zone in 2007 totaling 2,000m in this shallow copper mineralization 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, magnetotellurics, an airborne gravity survey in the vicinity of the Lyndhurst deposit, the #1 Copper –Silica Zone and Moses Zone, all of which culminated with an eight (8) hole relatively shallow drill program of 2,942 metres without encountering any significant new VMS mineralization.

In 2011, a 56.5 ln-km dipole-dipole IP survey at 100 metre line separating was completed over the western half of the property covering a strike length of approximately 4.5 km extending westward immediately 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 (>200m) of the disseminated and stringers sulphides found at surface at both the main Beattie Zinc showing and Beattie North zinc stinger zone, thus identifying a priority drill target.

In 2012, from November 26 to December 9, a single deep, 997 metre 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 referred to as the Beattie Zinc Showing and Beattie North Stringers at vertical depths of respectively 325 metres and 650 metres.  No significant zones of copper/zinc bearing massive sulphides were encountered although intermittent and wide (75-100 metre core length) haloes of weak chalcopyrite or sphalerite, pyrite-quartz stringers, with local intense black chlorite alteration were intersected at both anticipated down dip projections of the surface sulphide occurrences within the thick sequence of hydrothermally altered quartz phyric rhyolite flows and pyroclastic units.  A subsequent 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 any significantly sized conductive massive sulphide lens within an estimated 100 metre of the drill hole.

Exploration and Development

In 2013 a review of all available exploration data along with punctual selective surface mapping were undertaken and it was concluded that the property scale exploration potential for blind, potentially large VMS deposits within the extensively hydrothermally altered Lyndhurst felsic volcanic complex, decidedly lies below a minimum vertical depth of 800 metres.  In November, 2013, 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 the conductive, deeply buried sulphides. 

In the light of these findings, it is concluded that any meaningful further deep exploration work would require or essentially be restricted to stratigraphic drilling.  Several deep targets have yet to be fully assessed and these will be given further consideration in 2014.  Scrutinization of the exploration data in the less explored eastern portion of the volcanic complex will be undertaken to assess whether any deep drill targets can be identified in the context of Globex’s continuing efforts to locate, yet undiscovered large, deep seated high grade VMS Cu/Zn/Ag/Au deposits in this persistently enticing volcanogenic setting.

Elsewhere approximately $100,000 was expended in 2013 on the continuing reclamation work in the immediate vicinity of the old mine workings.  Work included permanent securement with cement caps, of the mine shaft and ventilation raise openings as well as the relocation into one consolidated depository of all mine waste material accumulated on surface.  This work is in preparation of the final restoration phase scheduled for completion prior to year end 2014.
